Abstract: This Draft Environmental Impact Statement (EIS) describes the effects of 

implementing five alternatives to manage fuels and vegetation in the Spears Project Area. The 

project area is located about 20 miles northeast of Prineville, Oregon within the Marks Creek 

Watershed and Veazie Creek Subwatershed. The project area encompasses nearly 39,200 acres. 

Alternative 4 is the preferred alternative and would treat fuels and vegetation on approximately 

16,740 acres, including 4,935 acres of commercial harvest. An estimated 12.3 million board feet 

(MMBF) would be harvested. Alternative 1 is the no action alternative and does not treat any 

acres. Implementation of any action alternative would necessitate amending the Forest Plan. 

Alternative 2 is the proposed action and would treat approximately 17,000 acres and harvest 

approximately 15.4 MMBF. Alternative 3 does not include any commercial timber harvest and 

would treat approximately 15,500 acres. Alternative 4 was developed in response to concerns 

related to road construction. Alternative 5 was developed in response to concerns related to 

wildlife habitats. Alternative 5 would treat approximately 15,850 acres and harvest 

approximately 8.9 MMBF. 

Reviewers should provide the Forest Service with their comments during the review period of 

the draft environmental impact statement. This will enable the Forest Service to analyze and 

respond to the comments at one time and to use information acquired in the preparation of the 

final environmental impact statement, thus avoiding undue delay in the decision-making process. 

Reviewers have an obligation to structure their participation in the National Environmental 

Policy Act process so that it is meaningful and alerts the agency to the reviewers’ position and 

contentions. Vermont Yankee Nuclear Power Corp. v. NRDC, 435 U.S. 519, 553 (1978). 

Environmental objections that could have been raised at the draft stage may be waived if not 

raised until after completion of the final environmental impact statement. City of Angoon v. 

Hodel (9th Circuit, l986) and Wisconsin Heritages, Inc. v. Harris, 490 F. Supp. 1334, 1338 (E.D. 

Wis. 1980). Comments on the draft environmental impact statement should be specific and 

should address the adequacy of the statement and the merits of the alternatives discussed (40 

CFR 1503.3).

CHAPTER 1. PURPOSE OF AND NEED FOR 

ACTION 

Document Structure 

The Forest Service has prepared this Environmental Impact Statement (EIS) in compliance with 

the National Environmental Policy Act (NEPA) and other relevant Federal and State laws and 

regulations. This EIS discloses the direct, indirect, and cumulative environmental impacts that 

would result from the proposed action and alternatives. The document is organized into four 

chapters: 

Chapter 1. Purpose and Need for Action: The chapter includes information on the history of the 

project proposal, the purpose of and need for the project, and the agency’s proposal for achieving 

that purpose and need. This section also details how the Forest Service informed the public of 

the proposal and how the public responded. 

Chapter 2. Alternatives, including the Proposed Action: This chapter provides a more detailed 

description of the agency’s proposed action as well as alternative methods for achieving the 

stated purpose. These alternatives were developed based on significant issues raised by the 

public and other agencies. This discussion also includes mitigation measures. Finally, this 

section provides a summary table of the environmental consequences associated with each 

alternative. 

Chapter 3. Affected Environment and Environmental Consequences: This chapter describes the 

environmental effects of implementing the proposed action and other alternatives. This analysis 

is organized by resource. 

Chapter 4. Consultation and Coordination: This chapter provides a list of preparers and 

agencies consulted during the development of the EIS. 

Index: The index provides page numbers by document topic. 

Appendices: The appendices provide more detailed information to support the analyses 

presented in the environmental impact statement. 

Additional documentation, including more detailed analyses of project area resources, may be 

found in the project record located at the Lookout Mountain Ranger District office in Prineville, 

Oregon. 

Purpose and Need for Action 

The purpose and need for this proposal was derived from evaluating current planning direction 

identified in the Forest Plan, identifying desired future conditions, and comparing them to the 

existing conditions in the project area. The 1998 Marks Creek Watershed Analysis, the May 
Chapter 1 - Purpose of and Need for Action 

Spears Vegetation Management Project Draft EIS ♦ Page 2 

2002 Addendum to the Marks Creek Watershed Analysis, and the December 2002 Bandit II 

Environmental Assessment were used as a basis for the existing condition. The purposes of this 

proposal are to: 

 1. Maintain and increase the abundance of late and old structure (LOS). 

 2. Reduce fuels and the potential for high-intensity wildfires. 

 3. Maintain conditions that would currently support low-intensity fires. 

 4. Reduce the susceptibility of the landscape to large-scale infestation by insects and 

disease. 

 5. Enhance hardwood communities, such as aspen and cottonwood. 

 6. Increase riparian vegetation and large tree structure in RHCAs. 

 7. Increase early-seral species composition. 

This action responds to the goals and objectives outlined in the Ochoco National Forest Land and 

Resource Management Plan as amended (Forest Plan), and helps move the project area towards 

desired conditions described in that plan. 

Late and Old Structure (LOS), Early-seral Species Composition, and 

Infestations by Insects and Disease 

The Forest Plan (p. 4-12) identifies a goal of maintaining forest health for present and future 

uses. The Forest Plan (p. 4-3) also has a goal to “maintain or enhance ecosystem functions to 

provide long-term productivity of forest resources and biological communities.” The objective 

associated with this goal is to provide for all seral stages of plant associations, with a distribution 

that is ecologically sound. The Interim Ecosystem Standard in the Eastside Screens (Appendix 

B, p. 4) states “characterize ... [the] watershed for patterns of stand structure ... and compare to 

the historic range of variability.” The Ochoco National Forest Viable Ecosystems Management 

Guide (Simpson et al. 1994) is a tool for analyzing each seral/structural stage for the plant 

associations found on the Ochoco National Forest. Managing an ecosystem within its range of 

natural (or historic) variability is a scientifically defensible way to maintain diverse, resilient, 

productive, and healthy systems (Swanson et al. 1994). 

The vegetative conditions in the Spears project area were characterized with the Viable 

Ecosystems Model (Simpson et al. 1994). This model was used to compare existing seral 

structural conditions to the historic range of variability (HRV). The model focuses on 

relationships between combinations of vegetation structure and species composition. Based on 

the comparison of seral structural conditions, there are too many areas dominated by trees from 5 

to 20.9 inches in diameter at breast height (dbh) and not enough areas dominated by large trees 

(greater than 21 inches dbh). Many areas have dense tree stocking in the understory and the 

abundance of species such as Douglas-fir and grand fir (late-seral species) has increased. 

Late and old structure (LOS) is the vegetative stage in which large trees are common. Large 

trees are 21 inches dbh or larger. Historically, the amount of LOS within the project area would 

have ranged from approximately 10,600 to 20,200 acres. Today, the amount of area classified as 

LOS is approximately 5,650 acres, which is well below the HRV. 
Chapter 1 - Purpose of and Need for Action 

Spears Vegetation Management Project Draft EIS ♦ Page 3 

LOS is classified into two types, multi or single strata. Multi-strata LOS has several strata of 

trees present. Single-strata LOS is more open and has a single stratum of large trees and young 

trees are absent or only a few exist in the understory. Historically, the single strata condition was

the most common type of LOS in the project area, ranging from approximately 8,000 to 15,000 

acres in abundance. Approximately 1,900 acres of single-strata LOS exists within the project 

area. Historically, multi-strata LOS ranged from 2,600 to 5,300 acres in the project area. 

Currently, there are approximately 3,700 acres classified as multi-strata LOS in the project area. 

Today, about 65 percent of the existing LOS is multi-strata compared to about 25 percent 

historically. 

The current departure from historic LOS conditions is primarily a result of past timber harvest 

(which removed large trees from the landscape), the Hash Rock Fire of 2000 (in which an 

estimated 940 acres of LOS were lost), and fire exclusion. Fire exclusion over the past 90 years 

has encouraged the establishment and development of late-seral, shade-tolerant understory trees 

such as grand fir within what were once open stands of primarily early-seral large trees. 

Historically, stands were less dense, contained a higher percentage of fire-tolerant species such 

as ponderosa pine and western larch, and had more open understory conditions. When stands 

become denser, additional competitive stress is placed on the remaining large trees. Trees under 

competitive stress are less vigorous, grow slower, and are more prone to being killed by insects 

and disease. Dense multi-strata stands are also more prone to stand replacement wildfire due to 

the presence of ladder fuels and increased canopy density. 

Given the relatively low amount of large trees and the time and growth needed to develop large 

trees, it is important to take action now to increase the resiliency of large trees and increase 

growth rates in smaller trees by reducing competition. Competition from intermediate and 

suppressed trees in ponderosa pine stands reduces growth of the large dominant and codominant 

trees (Cochran 1993). Removing small and medium sized trees (trees less than 21 inches dbh) 

will reduce competitive stress and reduce the amount of area with overstocked stands. 

Overstocked stands are slow growing because of competition and are less resistant to insects and 

disease. Removing trees less than 21 inches dbh would reduce stand density and move multicanopied (multi-strata) stands towards single canopied (single-strata) stands. This would 

maintain these stands longer into the future. Based on the low levels of LOS in the project area, 

there is a need for (1) increasing the abundance of LOS within the Spears Project Area, 

especially single-strata LOS; (2) maintaining the existing amount of LOS; (3) maintaining 

existing large trees and encouraging the development of additional large trees; and (4) reducing 

competition among trees and reducing susceptibility to infestations by insects and disease. 

Removing smaller, understory trees would: 

 1. Maintain and increase the future abundance of LOS by reducing competition. 

Precommercial and commercial thinning would reduce stand densities to recommended stocking 

levels. This would encourage increased growth rates on the remaining trees allowing them to 

become large trees more rapidly. Precommercial and commercial thinning would also remove 

trees with damage or disease and those weakest trees unlikely to ever become large trees. 

Reducing stand densities, removing ladder fuels, and reducing fuel loadings would also improve 

the likelihood of younger/smaller trees reaching large tree size without being killed in a wildfire. 
Chapter 1 - Purpose of and Need for Action 

Spears Vegetation Management Project Draft EIS ♦ Page 4 

Precommercial and commercial thinning would remove understories which have developed in 

the absence of frequent, low-intensity wildfire, moving stands from multi towards single strata. 

Precommercial thinning and underburning will maintain stands which are currently single strata 

by removing small trees before they develop into a full canopy stratum. 

 2. Maintain LOS by reducing the likelihood of a stand replacement wildfire. Removing 

ladder fuels and reducing crown densities through precommercial and commercial thinning 

would raise canopy base height, reduce canopy bulk density, and reduce the potential for a highintensity wildfire. Treatment of activity-generated and natural fuels would reduce surface fire 

intensity, lower flame heights, and reduce the potential for large trees to be killed. 

 3. Improve stand health by increasing vigor and reducing susceptibility to insect and 

disease related mortality. Reducing competition would allow the large trees to maintain or 

increase vigor, thus reducing their susceptibility to being killed by insects and disease. 

Precommercial and commercial thinning would reduce the number of smaller trees, thus 

increasing the growing space available for the remaining large trees. Underburning would also 

reduce the number of small trees, although it is mostly effective on only the smallest trees or fireintolerant species, such as grand fir. 

 (4) Increase early-seral species composition. Precommercial and commercial thinning, as 

well as underburning, will favor the retention of species which were more abundant historically. 

Fire-tolerant, early-seral species such as ponderosa pine and western larch would be favored for 

retention while fire-intolerant species such as grand fir would be targeted for removal. Stands of 

predominately fire-tolerant species would be more likely to survive a future wildfire.

The Forest Plan (p. 4-9) identifies a goal to “Provide for the ecologically sound use of prescribed 

fire as a cost-effective management tool for achieving resource management objectives.” The 

Forest Plan (p. 4-10) also identifies objectives related to prescribed burning. These objectives 

relate to reducing wildfire intensities to support a cost-efficient fire protection organization, and 

emulating the natural role of fire in maintaining environmental diversity and site productivity. 

Since the Forest Plan was developed, there have been several efforts that stress the importance of 

reducing hazardous fuels and restoring healthy ecosystems. In April 1999, the General 

Accounting Office (GAO) in a report to Congress concluded that “the most extensive and serious 

problem related to the health of national forests in the interior West is the over-accumulation of 

vegetation.” The GAO report criticized the Forest Service for not having “clear goals, 

objectives, direction, and budgets that adequately address ecosystem restoration and maintenance 

needs.” 

In April 2000, the Forest Service responded with “A Cohesive Strategy for Protecting People and 

Sustaining Resources in Fire-Adapted Ecosystems” (Cohesive Strategy). This strategy addresses 

the hazards and risks from unnatural over-accumulations of fuels in high-frequency, lowintensity fire regimes, and the wildfires in these regimes which burn at high levels of severity. 

The purpose of the Cohesive Strategy (p. 10) is to restore and maintain health in fire-adapted 

ecosystems across the interior West. The Cohesive Strategy outlines prescribed fire and 

mechanical fuels treatments to reduce the hazards and risks. 
Chapter 1 - Purpose of and Need for Action 

Spears Vegetation Management Project Draft EIS ♦ Page 5 

Later that same year, the National Fire Plan was developed with the intent of actively responding 

to severe wildland fires and their impacts to communities. The National Fire Plan recognizes 

that wildland fires play an integral role in many forest and rangeland ecosystems; however, 

decades of fire exclusion efforts have disrupted the natural fire regimes. 

In August 2001, a 10-Year Comprehensive Strategy for reducing wildland fire risks was issued. 

The Comprehensive Strategy outlines an approach to “reduce the risks of wildfire to 

communities and the environment.” 

In August 2002, the President announced the Healthy Forests Initiative (HFI). The HFI 

recognized that “forest and rangelands of the West have become unnaturally dense, and 

ecosystem health has suffered” and that “these unhealthy forests, overloaded with fuels, are 

vulnerable to unnaturally severe wildfires.” Congress responded in part to the HFI by passing 

the Healthy Forest Restoration Act to help reduce hazardous fuels and restore healthy forest and 

rangeland conditions. 

In July 2005, the Crook County Community Wildfire Protection Plan (CWPP) was approved. 

This plan designated a large portion (more than half) of the Spears project area as Wildland 

Urban Interface (WUI). In the Crook County CWPP, this area was identified as an area to 

expedite WUI hazardous fuels treatments. This WUI area includes all land in the project area 

southeast of U.S. Highway 26, all private property, and lands northwest of U.S. Highway 26 for 

its entire length. U.S. Highway 26 is a major egress and ingress route for the Marks Creek 

watershed. Unplanned ignitions have the potential to affect private property, recreation users, 

and the electronic equipment at Viewpoint communication site. In November 2006, the Wheeler 

County CWPP was approved. The Wheeler County CWPP also identified WUI in the northeast 

portion of the Spears project area. 

Historically, the dominant disturbance factor in the project area was frequent, low-intensity fire 

that eliminated the majority of seedlings and saplings. Most of the Spears project area had a 

short fire return interval, typically returning every 5 to 25 years. Frequent, low-intensity fires 

helped to maintain open stands of large trees, dominated by ponderosa pine. These frequent fires 

resulted in low levels of surface fuels. In the absence of frequent, low-intensity fires, forest 

stands in the project area have developed multi-canopy conditions, stocking levels have 

increased, ladder fuels have increased, surface fuels have increased, and the abundance of lateseral, fire-intolerant species (such as grand fir) has increased. These changes from historic 

conditions have left forested stands susceptible to high-intensity wildfire, with an increased 

potential for the unwanted loss of trees, water quality, soil productivity, wildlife habitat, and 

other forest resources. High-intensity wildfires caused by these conditions also limit the 

suppression options available to firefighters, decreasing the safety, efficiency, and economy of 

fire suppression. 

Hardwood Plant Communities 

The Forest Plan (p. 4-3) identifies a goal of maintaining “native, historic, and desirable introduced 

plant and animal species and communities.” The Forest Plan (p. 4-32) identifies a desired future 

condition where hardwoods such as cottonwood, aspen, alder, and willow will be more common 
Chapter 1 - Purpose of and Need for Action 

Spears Vegetation Management Project Draft EIS ♦ Page 6 

along streams, meadows, and wet areas. In other words, the desired future conditions is to have 

well distributed and vigorous hardwood communities across the project area. The Forest Plan 

standards and guidelines (p. 4-121) state “manage aspen stands to produce a vigorous population, 

forest-wide.” The 1998 Marks Creek Watershed Analysis (p. 114) recommends that aspen and 

cottonwood stands be re-invigorated by thinning conifers within and adjacent to clones. 

Both cottonwood and aspen grow in self-perpetuating clones in areas of locally high moisture such 

as meadows, seeps, and adjacent to streams. Conifer trees are encroaching into aspen and 

cottonwood stands in the project area. These conifers compete with the hardwood trees for light, 

moisture, and growing space. Since the hardwood trees are not shade tolerant, they can be 

shaded out by the encroaching conifers, which results in loss of vigor for the hardwoods in the 

short term, and can lead to loss of the clone(s) in the long term. There is a need for more 

vigorous aspen and cottonwood stands. 

Removing conifer trees within and adjacent to aspen and cottonwood stands would reduce 

competition for light, moisture, and growing space. Reducing competition would also improve 

the vigor of hardwood stands and prevent a decline in the abundance, distribution, and extent of 

hardwood communities within the project area. 

Riparian Habitat Conservation Areas (RHCAs) 

In 1995, the Decision Notice for the Inland Native Fish Strategy (INFISH) was signed and 

amended the Ochoco Forest Plan. The INFISH established Interim Riparian Management 

Objectives for several fish habitat features. 

The Forest Plan emphasis for riparian areas is to manage streamside vegetation and habitat to 

maintain or improve water quality. Forest Plan goals for riparian vegetation includes providing 

“an amount and distribution of large woody debris characteristic of natural aquatic and riparian 

ecosystems; and habitat to support populations of well-distributed native and desired non-native 

plant, vertebrate, and invertebrate populations that contribute to the viability of ripariandependent communities” (INFISH, pp. A-1 to 2). 

The amount and type of vegetation in riparian areas plays an important role in the maintaining 

and improving both water quality and fish habitat. The increasing amount of conifers in RHCAs 

prevents woody vegetation such as alder, willow, aspen, and shrubs from expanding. Conifers 

within RHCAs compete with these species for nutrients. Many of these broadleaf species are 

shade-intolerant; throughout the project area conifers are shading these brushy, shrubby species, 

and they are losing vigor. The roots of woody vegetation helps to stabilize streambanks and the 

stems act as a roughness element that reduces the velocity and erosive energy of over bank flow 

during high water events. Conifers do not provide the same bank stabilizing function as these 

brushy, shrubby species. 

Based on stream surveys, the project area is deficient in the amount of large woody material in 

streams. Large woody material provides aquatic habitats and shade for streams. Redband trout, 

like many other salmonids, have evolved in stream systems in which large woody material helps 

retain organic and inorganic particulate matter that is important for channel stability, biological 
Chapter 1 - Purpose of and Need for Action 

Spears Vegetation Management Project Draft EIS ♦ Page 7 

diversity, and productivity (Nakamura and Swanson 1993). Large wood influences habitat for 

fish and other aquatic organisms by serving as energy dissipaters, flow deflectors, and dams. 

Large woody material in streams and the adjacent flood plain provides streambank stability, 

decreases flow velocities, increases storage time (decreases downstream flood risk), and stores 

sediment. Large trees are needed in RHCAs because they become large woody material when 

they fall. 

There is a need for fewer conifers within RHCAs. Reducing the amount of conifers within 

RHCAs would (1) encourage alder, willow, aspen, and other broadleaf species to expand, and (2) 

increase the growth rates of remaining conifers in RHCAs so they grow larger and can 

eventually provide future large wood to streams. 

Proposed Action 

The Lookout Mountain Ranger District is proposing to manage vegetation through commercial 

timber harvest, precommercial thinning, and fuel reduction activities to meet the purpose and 

need. The proposed action includes approximately 6,172 acres of commercial harvest, 11,160 

acres of precommercial thinning, and 196 acres of thinning in hardwood stands. Fuel reduction 

activities include approximately 15,464 acres of prescribed fire, and 3,015 acres of grapple and 

718 acres of hand piling. Commercial harvest includes tractor, skyline, and helicopter logging 

systems. Areas identified as tractor logging are areas where heavy equipment, such as logging 

tractors/skidders, will be used to remove a commercial product. Road construction activities 

include 18.0 miles of new road construction, and 12.0 miles of reconstructing roads on an 

existing road bed. Newly constructed roads and roads that are reopened would be closed after 

harvest activities are complete. A complete description of the proposed action (Alternative 2) is 

contained in Chapter 2. 

Project Area 

The project area is located about 20 miles northeast of Prineville, Oregon. U.S. Highway 26 

bisects the project area. The project area lies within portions of T. 12 S., R. 19 E.; T. 12 S., R. 20 

E.; T. 13 S., R. 18 E.; T. 13 S., R. 19 E.; T. 13 S., R. 20 E.; T. 14 S., R. 18 E.; T. 14 S., R. 19 E.; 

Willamette Meridian. Map 1 (vicinity map) displays the project area. 

The project area is comprised of approximately 39,200 acres primarily within the Marks Creek 

watershed. Marks Creek flows into Ochoco Creek, approximately 6 miles above Ochoco 

Reservoir, and is a part of the Deschutes/Crooked River Basin. Elevations range from 5,985 feet 

above sea level on Wildcat Mountain on the western edge of project area to 3,360 feet where 

Marks Creek joins Ochoco Creek. 

There are several tracts of private land (2,325 acres) within the project area boundary. 
Chapter 1 - Purpose of and Need for Action 

Spears Vegetation Management Project Draft EIS ♦ Page 8 

Forest Plan Direction 

This project is tiered to the 1989 Final Environmental Impact Statement (FEIS) for the Ochoco 

National Forest Land and Resource Management Plan (Forest Plan), as amended by the 1995 

Revised Continuation of Interim Management Direction Establishing Riparian, Ecosystem, and 

Wildlife Standards for Timber Sales (Eastside Screens), the 1995 Inland Native Fish Strategy 

(INFISH), and the 2006 Pacific Northwest Region Invasive Plant Program EIS. The Forest Plan 

direction, including standards and guidelines, are based on these documents and were used in 

developing the proposed activities. 

There are 13 Forest Plan management areas in the project area. A management area is 

“composed of lands with similar capabilities or characteristics” (Forest Plan, p. 4-45). Each 

management area has specific goals, desired future conditions, and standards and guidelines. 

The location of these management areas is depicted on Map 2. The emphasis for each of the 

management areas is briefly described below. 

MA-F3 Mill Creek Wilderness - Protect the Wilderness ecosystem. Manage use to maintain a 

natural setting and preserve solitude (Forest Plan, p. 4-52). The project area includes 

approximately 3,650 acres of the Mill Creek Wilderness. No activities are proposed within this 

management area. 

MA-F5 Research Natural Area - Allow natural processes to occur for research purposes 

(Forest Plan, p. 4-56). The project area includes approximately 1,000 acres of the Ochoco 

Divide RNA. No activities are proposed within this management area. 

MA-F6 Old Growth - Habitat will be provided for wildlife species dependent upon old-growth 

stands (Forest Plan, p. 4-58). The project area contains an estimated 821 acres of allocated old 

growth. 

MA-F7 Summit Historic Trail - Protect the existing integrity of the Summit Trail. Enhance 

and interpret significant segments for public enjoyment and education. Pristine segments will be 

managed to protect, interpret, and preserve their historic qualities (Forest Plan p. 4-60). The 

project area includes an estimated 972 acres of the Summit Historic Trail management area. 

MA-F13 Developed Recreation - Provide safe, healthful, and aesthetic facilities for people to 

utilize while they are pursuing a variety of recreational experiences within a relatively natural 

outdoor setting (Forest Plan, p. 4-71). The project area includes 69 acres within the developed 

recreation management area. 

MA-F14 Dispersed Recreation - Provide and maintain a near-natural setting for people to 

utilize while pursuing outdoor recreation experiences (Forest Plan, p. 4-72). The project area 

includes 52 sites that were identified in the Forest Plan as dispersed recreation sites. 

MA-F15 Riparian and RHCA - Manage streamside vegetation and habitat to maintain or 

improve water quality. The INFISH delineated Riparian Habitat Conservation Areas (RHCAs) 
Chapter 1 - Purpose of and Need for Action 

Spears Vegetation Management Project Draft EIS ♦ Page 9 

where riparian-dependent resources receive primary emphasis. These RHCAs include traditional 

riparian corridors, wetlands, intermittent streams, and other areas that help maintain the integrity 

of aquatic ecosystems. RHCAs encompass the MA-F15 management area and are overlaid on 

other management areas. RHCAs are shown on the Fish Distribution Map (Map 3 located at the 

end of this EIS). There are an estimated 4,546 acres within RHCAs. 

MA-F16 Bandit Springs Recreational Area - Provide dispersed, nonmotorized recreational 

opportunities within a setting where most management activities are generally not evident to the 

casual observer. Periodic manipulation of vegetation to meet recreation and visual objectives for 

the area will be apparent to the user. Timber stands will be managed to develop and maintain 

resistance to catastrophic events that would detract from the recreational experience (Forest Plan, 

pp. 4-76 and 4-77). The Bandit Springs Recreation Area is 1,580 acres. 

MA-F20 Winter Range - Manage for big game winter range habitat (Forest Plan, p. 4-82). The 

project area includes an estimated 3,824 acres of winter range. 

MA-F21 General Forest Winter Range - Manage for timber production with management 

activities designed and implemented to recognize big game habitat needs (Forest Plan, p. 4-84). 

The project area includes an estimated 2,428 acres within this management area. 

MA-F22 General Forest - Produce timber and forage while meeting the Forest-wide standards 

and guidelines for all resources. In ponderosa pine stands, management will emphasize 

production of high value (quality) timber (Forest Plan, p. 4-86). There are an estimated 16,792 

acres of general forest within the project area. 

MA-F25 U.S. Highway 26 Visual Corridor - Maintain and enhance the scenery for travelers 

along U.S. Highway 26 (Forest Plan, p. 4-93). The project area includes 5,586 acres within the 

U.S. Highway 26 Visual Corridor. 

MA-F26 Visual Management Corridors - Maintain the natural-appearing character of the 

Forest along major travel routes, where management activities are usually not evident or are 

visually subordinate to the surrounding landscape (Forest Plan, p. 4-95). The project area 

includes approximately 400 acres in visual management corridors outside the U.S. Highway 26 

corridor. 

Decision Framework 

The responsible sfficial for this proposal is the Forest Supervisor of the Ochoco National Forest. 

The responsible oOfficial will decide whether to: 

 1. Select the proposed action, or 

 2. Select an action alternative that has been considered in detail, or 

 3. Modify an action alternative, or 

 4. Select the no-action alternative, and 

 5. Identify what mitigation measures and monitoring will apply. 
Chapter 1 - Purpose of and Need for Action 

Spears Vegetation Management Project Draft EIS ♦ Page 10 

The responsible official will decide whether to conduct commercial timber harvest, 

precommercial thinning, hardwood thinning, and fuels reduction activities in the Spears project 

area. The decision will be determined by how well each alternative provides the best mix of 

prospective results in regard to the purpose and need, the issues, types and levels of effects, and 

public comments. The responsible official will consider: 

 1. Would LOS be maintained and increased? Would the amount of single-strata LOS be 

increased? Would stand density be reduced to remove competitive stress on large trees? Would 

the management activities result in more large trees being maintained over time, as well as 

encourage the development of additional large trees? 

 2. Would the density and species composition of forested stands be modified towards a 

balance of seral/structural stages as described by the historic range of variability? Would the 

susceptibility of the landscape to large-scale infestation by insects and disease be reduced? 

Would forested stands shift toward dominance by early-seral, fire-tolerant species such as 

ponderosa pine and western larch? 

 3. Would surface fuels, ladder fuels, and stand density be reduced to decrease the 

susceptibility to high-intensity wildfire? Would the abundance of late-seral, fire-intolerant 

species (such as grand fir) be reduced? Would fire regimes move toward those that occurred 

historically? 

 4. Would maintenance underburning occur to maintain conditions that currently support 

low-intensity fires? 

 5. Would the vigor of hardwood stands be improved? Would the competition with 

conifers be reduced? Would the abundance, distribution, and extent of hardwood communities 

within the project area be maintained or increased? 

 6. Would the proposed activities contribute toward meeting the interim Riparian 

Management Objectives contained in INFISH? Would the proposed activities in RHCAs 

encourage alder, willow, aspen, and other broadleaf species to expand? Would the proposed 

activities accelerate the development of large trees so they provide future large wood to streams? 

Public Involvement 

The Notice of Intent (NOI) was published in the Federal Register on June 2, 2006. The NOI 

requested public comment on the proposal by June 26, 2006. On May 23, 2006, as part of the 

public involvement process, the agency mailed letters to 63 individuals, organizations, adjacent 

landowners, and other potentially interested organizations, including tribal agencies. 

Forest Service staff also met with members of the Crook County Natural Resources Planning 

Committee to discuss the Spears Project on three occasions (March 27, 2006, June 6, 2006, and 

January 4, 2007). Two field trips to the project area were held. The first field trip was on June 

6, 2006, and the second was on August 30, 2006. 
Chapter 1 - Purpose of and Need for Action 

Spears Vegetation Management Project Draft EIS ♦ Page 11 

The Spears Project has also been listed in the Ochoco National Forest Schedule of Proposed 

Actions since the Spring 2006 edition. 

In response to public involvement efforts, the Forest Service received comments from nine 

individuals, organizations, groups, and tribes. Using these comments from the public, the 

interdisciplinary team developed a list of issues to address. 

Issues 

The Forest Service separated the issues into three groups: significant, other, and non-significant 

issues. Significant issues were defined as points of discussion, debate, or dispute about 

environmental effects that may occur as a result of the proposed action. Significant issues were 

used to develop alternatives and design elements or resource protection measures. Other issues 

were defined as concerns related to the proposed action. Non-significant issues were identified 

as those: (1) outside the scope of the proposed action; (2) already decided by law, regulation, 

Forest Plan, or other higher level decision; (3) irrelevant to the decision to be made; or (4) 

conjectural and not supported by scientific or factual evidence. The Council on Environmental 

Quality regulations explain this delineation in Sec. 1501.7, “...identify and eliminate from 

detailed study the issues which are not significant or which have been covered by prior 

environmental review (Sec. 1506.3).” 

Significant Issues 

The Forest Service identified two issues from the scoping comments that led to alternative 

development. The first issue related to road construction. Comments suggested that the 

proposed action included too much road construction. Other comments suggested that the road 

density in the project area was too high and should be reduced. Some comments indicated that 

roads cause fragmentation and affect water quality. Alternative 4 was developed with an 

emphasis on using existing roads and minimizing new road construction. Alternative 4 does 

include some new road construction; new road segments are generally less than 0.25 miles. 

Other comments related to roads suggested that additional roads should be closed. All of the 

newly constructed roads in Alternatives 2, 4, and 5 will be closed after use. In addition, some 

currently open roads will be closed and other roads will be decommissioned. The amount of 

road construction, reconstruction, closure, and decommissioning varies by alternative. The 

alternative descriptions in Chapter 2 provide information on road work included in each 

alternative. The differences between alternatives are measured by the amount of road 

construction, reconstruction, and decommissioning. 

The second issue that led to developing an alternative was related to wildlife. Comments related 

to wildlife included concerns about habitat for goshawks, pileated woodpeckers, elk, cavitynesting birds, and neotropical migratory birds. Alternative 5 was developed by comparing the 

proposed action to a variety of wildlife habitats such as pileated woodpecker feeding habitat 

(pfh), goshawk post-fledging areas (PFA), elk satisfactory cover (70% canopy closure) in winter 

range, connective corridors (Eastside Screens), and special habitats such as aspen and 

cottonwood stands. Alternative 5 was developed to include a greater emphasis on variable 
Chapter 1 - Purpose of and Need for Action 

Spears Vegetation Management Project Draft EIS ♦ Page 12 

density thinning and retention of dense patches of vegetation within these wildlife habitats. The 

differences between alternatives are measured by the activities within and changes to goshawk 

and pileated woodpecker habitat. For elk, the differences between alternatives are measured by 

the change in the Habitat Effectiveness Index (HEI). 

One commenter suggested that the project should establish conditions for effective winter range 

use by deer and elk. All of the alternatives were designed to meet Forest Plan standards for 

winter range. Alternative 5 was developed with an added emphasis on wildlife habitat including 

habitat in winter range. The effects of each of the alternatives on winter range are disclosed in 

Chapter 3 under the elk section. 

One commenter stated that they supported variable density thinning that allows young forests to 

develop into more complex and resilient forests. All of the action alternatives include variable 

density thinning. Alternative 5 was developed with an emphasis on wildlife habitat and includes 

a greater emphasis on variable density thinning and retention of dense patches of vegetation in 

certain wildlife habitats. 

In the scoping letter and the Notice of Intent to prepare an EIS, the Forest Service indicated that 

it was considering an alternative that included only precommercial thinning and prescribed fire 

activities. Several comments suggested that an alternative should be considered that did not 

include commercial harvest or road construction. Other comments suggested that an alternative 

should be considered that included a diameter limit of 10 or 14 inches dbh. Alternative 3 does 

not include any commercial harvest, road construction, and limits thinning to trees less than 12 

inches dbh. 

Some commenters suggested that snags should be harvested, while others suggested that snags 

should be retained and additional snags should be created. The level of snags across the project 

area varies. In the Hash Rock Fire area, there are many snags. Over the last 30-35 years, about 

7,500 acres have been harvested. These areas are deficient in snags. Across the project area, the 

number of snags is estimated to average about 65 percent of the maximum potential population. 

The Eastside Screens indicates that snags should be maintained at 100 percent of potential 

population levels. Because the amount of snags is less than 100 percent of potential population 

levels, none of the alternatives include harvesting snags with the exception of snags that pose a 

safety hazard. 

Other Issues 

Some comments indicated that commercial harvest and precommercial thinning should only be 

allowed in RHCAs where these actions would benefit riparian management objectives. Part of 

the Purpose and Need for this project is to encourage vegetative diversity in RHCAs and increase 

the future availability of large wood. All of the activities in RHCAs in the action alternatives 

have been proposed to promote attainment of riparian management objectives. 

One commenter stated that the proposed action should not create or leave excessive levels of 

untreated slash. All of the action alternatives include activity-fuels treatments, such as 
Chapter 1 - Purpose of and Need for Action 

Spears Vegetation Management Project Draft EIS ♦ Page 13 

underburning, grapple piling, and hand piling. In addition, where precommercial thinning is 

proposed in some plantations, slash will be lopped. 

A few comments expressed concerns related to effects on soils. Chapter 3 includes a discussion 

of the expected effects on soils. Appendix B includes a unit-by-unit analysis of soil conditions. 

Two commenters suggested that the effects of OHV use needed to be considered and that 

targeted mitigation to reduce OHV use needed to be included in the EIS. Where appropriate, the 

effects of OHV use are discussed under the cumulative effects sections in Chapter 3. Targeted 

mitigation to reduce OHV use was not considered in detail in this EIS because it is outside the 

scope of this project. However, the Deschutes and Ochoco National Forests are beginning a 

Travel Management project that will result in identifying roads, trails, and areas where motorized 

use, including OHVs, will be allowed. 

One commenter suggested that the primary cause of decline in hardwood communities is 

excessive livestock grazing. There are several causes for hardwood decline including 

competition with conifers, stream down cutting, excessive vegetation upslope of hardwoods, 

road diversions, and browse by both livestock and wildlife. All action alternatives include 

reducing conifer competition in several aspen and cottonwood stands. In conjunction with 

thinning conifers, fencing would be constructed around many of these stands to reduce browse 

pressure. 

One commenter suggested that the hydrologic impacts of roads should be analyzed. The Water 

Quality discussion in Chapter 3 includes a discussion of the hydrologic impacts of roads. 

One commenter stated that the project area contained unroaded areas adjacent to the Mill Creek 

Wilderness and the Ochoco Divide Research Natural Area (RNA) and that the EIS should fully 

analyze any effects to roadless areas and values. The Draft EIS does not analyze effects to 

roadless areas and values because there are no inventoried roadless areas within the project area. 

The areas identified as “unroaded” by the commenter are generally small. Several of these small 

areas are in the Bandit Springs Recreation Area, which is adjacent to the Mill Creek Wilderness. 

As mentioned previously, the emphasis in this area is to provide dispersed, nonmotorized 

recreational opportunities within a setting where most management activities are generally not 

evident to the casual observer. None of the alternatives include any road construction in the 

small areas within the Bandit Springs Recreation Area that the commenter identified as 

unroaded. The Bandit Springs Recreation Area would continue to be managed for nonmotorized recreation. Southwest of the Bandit Springs Recreation Area, the commenter 

identified an area primarily in Sections 18 and 19, between the Mill Creek Wilderness and U.S. 

Highway 26. This area has already been developed and includes several roads and evidence of 

past logging activities. Roads in this area include U.S. Highway 26, 3350, 3350-100, 3350-102, 

3350-103, 3350-209, and unclassified roads that are not numbered. Another area the commenter 

identified as unroaded encompasses the Ochoco Divide RNA and straddles the watershed 

boundary. This area is only partially within the project area. None of the alternatives proposed 

any road construction in this area, with the exception of a short spur road to access Unit 887 in 

Alternative 2. This short spur road would come off the 2630-013 in Section 36. This area has 

already been developed and contains several roads including the 2630-015, 2630-016, the 450 
Chapter 1 - Purpose of and Need for Action 

Spears Vegetation Management Project Draft EIS ♦ Page 14 

and 452 roads, and an “unclassified” road between the 2630-013 road and the 452 road. None of 

the areas identified by the commenter, with the possible exception of the area around the Ochoco 

Divide RNA, are undeveloped. Management emphasis within the Ochoco Divide RNA is to 

allow natural processes to occur for research purposes and education. None of the alternatives 

would alter the character of the Ochoco Divide RNA. 

Several commenters stated that the Agency must prioritize fuel treatment in areas that protect 

homes and communities. During the development of the proposed action, the interdisciplinary 

team identified several fuel treatment emphasis areas, including areas within the WUI. Fuel 

reduction activities were proposed in these areas to tie into treatment areas from past activities. 

These areas were labeled as fuel compartments and are displayed on Map 15 along with the 

Crook County identified WUI. Lands identified by Wheeler County have not yet been included 

in the Ochoco GIS system and are not displayed on Map 15. The following paragraphs describe 

the fuel compartments with an explanation of the areas to protect, past activities, and units 

identified in the Spears proposal that would reduce fire hazard. 

Fuel Compartment A: This emphasis area runs along Road 27, U.S. Highway 26, and access to 

private property. Within this area, maintenance burning and thinning along Highway 26 would 

occur. Within plantations slash would be lopped. Spears units (718, 719, 722, 723, 727, 729, 

and 401) have been interlinked with previously treated areas such as those from the McGinnis 

and Harpo timber sales and the Cougar underburn project. Spears units, combined with the Hash 

Rock fire and previous activities are designed to provide a buffer to the private property in this 

fuel compartment. 

Fuel Compartment B: This emphasis area partially surrounds the Ochoco Divide RNA, and runs 

along U.S. Highway 26 and Roads 2630 and 2210. These roads have been identified as 

ingress/egress routes. Within this area, maintenance burning and thinning along Highway 26 

would occur. Within plantations slash would be hand piled or lopped. The combination of 

treatments in this area is to increase the probability of a successful suppression action should an 

unplanned ignition occur in or near the RNA. 

Fuel Compartment C: This emphasis area includes NFS lands adjacent to private property and 

U.S. Highway 26. Within this area, maintenance burning and thinning along U.S. Highway 26 

would occur. This area includes Hamilton Butte. Underburning on and near Hamilton Butte 

occurred in the 1980s, 1990s, and in 2004. Activities in this area would tie the proposed Spears 

units with previous underburning and with thinning that occurred under the Harpo Timber Sale. 

Spears units in this area include 559, 560, 562, 876, 878, and 925. Spears units, combined with 

the previous activities, are designed to provide a buffer to the private property in this fuel 

compartment and increase the probability of successful suppression should an unplanned ignition 

occur. 

Fuel Compartment D: This emphasis area includes NFS lands adjacent to private property and 

U.S. Highway 26. Within this area, maintenance burning and thinning in previously treated units 

along U.S. Highway 26 would occur. Units will be grapple piled and/or underburned. There has 

been little management activity in the areas bordering private property to the south and west 

during the past 20 years. A high percentage of the area along private property contains 
Chapter 1 - Purpose of and Need for Action 

Spears Vegetation Management Project Draft EIS ♦ Page 15 

hazardous conditions. Activities in this area are designed to reduce surface and ladder fuels and 

reduce the hazardous conditions. Fuel reduction in this area would reduce the likelihood that an 

unplanned ignition will spread from NFS lands to private lands or vice versa. At this time, the 

private property adjacent to the National Forest is largely undeveloped and is used for livestock 

grazing and some timber production. 

Fuel Compartment E: This emphasis area includes areas along Road 3350 and U.S. Highway 26. 

These roads have been identified as ingress/egress routes. Within this area, maintenance burning 

and thinning of previously treated areas would occur. Thinning units will be grapple piled and/or 

underburned. This area also includes the Jim Elliott Old Growth Management Area (OGMA). 

Previous treatments along the west and southwest side of the OGMA occurred as part of the 

Thunder Project (timber sale and underburning). The east-northeast side of the OGMA has had 

little activity in the past 20 years. It is possible that an unplanned ignition on the east-northeast

side could enter the OGMA and render it unsuitable for pileated woodpeckers. If an unplanned 

ignition were to occur on a 97th percentile day, most of the OGMA would be expected to burn at 

high intensity because of the existing fuel loading and vegetation in the OGMA block. Spears 

units 109, 110, 163, 171, 174, 212, 814, 816, 818, 828, 832, 833, 935, 940, and 941 would 

reduce fuels near the OGMA and reduce the likelihood of an unplanned ignition spreading into 

the OGMA. 

Fuel Compartment F: This emphasis area includes areas along Road 3350 and the Mill Creek 

Wilderness. Within this area, maintenance burning and thinning of regeneration in previously 

treated units would occur. Regeneration units will be grapple piled and/or underburned. Spears 

units within this area are interlocked with previous treatments of the Felix and Harpo Timber 

Sales and Felix and Jackson Creek underburn projects. 

Fuel Compartment G: This emphasis area includes areas along the Mill Creek Wilderness 

boundary. Within this area, maintenance burning and thinning of previously treated areas would 

occur. Thinning units will be grapple piled and/or underburned. The Spears units would provide 

protection from unplanned ignitions entering the Mill Creek Wilderness and the Highway 26 

corridor from unplanned ignitions in adjacent forested areas. 

Fuel Compartment H: This emphasis area includes areas along Roads 2620, 2610, and 2610-

150. These roads have been identified as ingress/egress routes. Within this area, maintenance 

burning and thinning of previously treated areas would occur. Thinning units will be grapple 

piled and/or underburned. This area includes a goshawk nest site and post-fledging area. During 

the past 20 years, several underburning and timber harvest activities have occurred. Spears units 

306, 858, 860, 862, 863, and 946 would link with previously treated areas and provide a measure 

of protection to the ingress/egress routes and the goshawk nesting area.

Non-significant Issues 

Comments that were determined to be non-significant included statements such as reduce or 

remove livestock grazing or develop a long-term management strategy for the entire Lookout 

Mountain Ranger District. Other comments suggested that the purpose and need for action 

should be redefined to include restoration and wildlife were also determined to be nonsignificant. 

Some commenters suggested that trees greater than 21 inches dbh should be harvested to allow 

younger stands room to grow. This comment was not considered in detail because the amount of 

LOS across the landscape is deficient (see the Purpose and Need for Action). In addition, the 

Eastside Screens (part of the Forest Plan) already decided that all live trees greater than or equal 

to 21 inches dbh be maintained, unless the amount of LOS is above the HRV. 

One commenter stated that the project area contains many openings from past activities that have 

not successfully regenerated. The commenter suggested that the alternatives include 

reforestation activities in these areas. The available data for the project area indicates that in the 

last 3 decades there have been 112 units which were harvested with a regeneration prescription. 

With a regeneration prescription, reforestation is usually needed to restock the area following 

harvest. The Forest Plan (p. 4-205) indicates that stocking standards require a minimum of 50 

trees at least 4-1/2 feet tall be present before a stand can be certified as stocked. Out of 112 

units, there are 10 units which have not been certified as stocked. Of those, five units (totaling 

38 acres) were not planted because they were specifically harvested to provide telemark ski 

opportunities in the Bandit Springs Recreation Area; there are no plans to stock these five units. 

In the other five units, planting occurred in 2003. The number of trees per acre in these units 

range between 258 and 285 trees per acre; however, the trees are not yet taller than 4-1/2 feet.

CHAPTER 2. ALTERNATIVES, INCLUDING THE 

PROPOSED ACTION 

Introduction 

This chapter describes and compares the alternatives considered for the Spears Vegetation 

Management Project. It includes a description of each alternative considered. Maps of each 

alternative are located in Appendix C. This section also presents the alternatives in comparative 

form, sharply defining the differences between each alternative and providing a clear basis for 

choice among options by the decision maker and the public. 

Alternatives Considered but Eliminated from Detailed Study 

Federal agencies are required by NEPA to rigorously explore and objectively evaluate all 

reasonable alternatives and to briefly discuss the reasons for eliminating any alternatives that 

were not developed in detail (40 CFR 1502.14). Public comments received in response to the 

proposed action provided suggestions for alternative methods for achieving the purpose and 

need. Some of these alternatives may have been already decided by other decisions, duplicative 

of the alternatives considered in detail, or determined to be components that would cause 

unnecessary environmental harm. One alternative was briefly considered, but dismissed from 

detailed consideration. An alternative that would include harvesting trees greater than 21 inches 

dbh was eliminated from detailed study because it was inconsistent with the purpose and need. 

Alternatives Considered in Detail 

The Forest Service developed five alternatives in detail, including the no action and proposed 

action alternatives. Alternatives 4 and 5 were developed directly in response to issues raised by 

the public. 

Alternative 1 (No Action) 

Alternative 1 is the no action alternative. This alternative serves as a baseline for comparison of 

the effects of all of the alternatives. Under the no action alternative, no activities would be 

implemented to accomplish the stated purpose and need for the Spears Vegetation Management 

Project. 

Routine activities such as road maintenance and suppression of unplanned fires would continue. 

Activities authorized under separate decisions would also continue. These activities include 

livestock grazing and noxious weed treatments. Recreational use of the area, including camping, 

hunting, and motorized and non-motorized uses, would also continue. 
Chapter 2 - Alternatives 

Spears Vegetation Management Project Draft EIS ♦ Page 18 

Alternative 2 (Proposed Action) 

Alternative 2 is the proposed action. This alternative was developed to respond to the purpose 

and need. The proposed action includes approximately 6,172 acres of commercial harvest, 

11,160 acres of precommercial thinning, and 196 acres of thinning in hardwood stands. Fuel 

reduction activities include approximately 15,464 acres of prescribed fire, and 3,015 acres of 

grapple piling, and 718 acres of hand piling. Commercial harvest includes tractor, skyline, and 

helicopter logging systems. Areas identified as tractor logging are areas where heavy equipment, 

such as logging tractors/skidders, will be used to remove a commercial product. 

No trees greater than 21 inches dbh, live or dead, would be cut except those necessary to be 

removed for safety reasons or road construction. 

Stands selected for commercial and precommercial thinning have a large component of pole and 

small sized (less than 21 inches dbh) trees with dense stocking conditions. The objective of 

these treatments is to move stands towards late and old structural stage conditions in a more 

rapid timeframe than would occur with no treatment. Maps 4, 5, and 6 display the commercial 

harvest and road work, precommercial thinning and hardwood treatments, and fuels treatments 

for Alternative 2. 

Commercial harvest on slopes less than 35 percent would be implemented with ground-based 

harvest systems and the activity fuels will either be treated with prescribed fire, grapple piling, or

hand piling. Where there are short, steep pitches in tractor logging units, these areas may be 

harvested by methods such as pulling cable. On steeper slopes, such as those over 35 percent, a 

skyline or helicopter harvest system would be employed for soil protection. Helicopter harvest 

systems are also designated for areas with concerns about using ground-based systems. Map 4 

displays the logging systems associated with commercial harvest. 

Stands selected for fuels reduction activities are (1) stands with either commercial timber harvest 

or precommercial thinning where fuels are present as a result (activity fuels), (2) stands that 

exhibit a high level of fuels resulting from the natural accumulations of material, or (3) stands 

that currently exhibit low-intensity fire conditions and require periodic treatment to maintain that 

condition. The objective of these fuel reduction activities are to move stands towards or 

maintain conditions with lower fuel loadings to approximate conditions when fire occurred at 

lower intensities and higher frequencies. 

Stands selected for hardwood thinning contain aspen or cottonwood clones where conifers are 

encroaching and competing with the hardwoods. After thinning is complete in these stands, 

slash will be treated with a combination of methods including lop and scatter, arranging slash to 

protect sprouts, and/or hand piling. Temporary exclosures will be constructed to protect sprouts 

in fourteen hardwood stands. Caging of individual sprouts will occur in five hardwood stands. 

Appendix A includes a description of the proposed treatments and a table showing the 

prescriptions for each unit included in Alternative 2.

Road construction activities include 18.0 miles of new road construction, and 12.0 miles of 

reconstructing roads on an existing road bed. Newly constructed roads and roads that are 

reopened would be closed after harvest activities are complete. 

The Roads Analysis Report for the Bandit II Project Area was updated for the Spears project and 

is contained in the project record. The following is a list of roads that will be constructed; these 

roads will be closed after harvest activities are complete.

Group (PAG). The Douglas-fir PAG is currently within the Historic Range of Variability (HRV) 

for multi-strata LOS and below the HRV for single-strata LOS. Timber harvest would occur in 

multi-strata LOS within the Douglas-fir PAG to reduce competition and maintain large trees in 

this area; these stands would be converted to single-strata LOS. Following treatment, multistrata LOS would be below HRV. The second amendment would allow commercial timber 

harvest within connective corridors. This activity is designed to maintain existing large trees and 

promote development of additional large trees within corridors; however, commercial harvest 

would reduce the canopy closure to less than two-thirds of site potential. The third amendment 

would allow precommercial thinning, hand piling, and underburning in the Stewart Springs Old 

Growth Management Area (OGMA). These activities are proposed to improve the longevity of 

large ponderosa pine on south and west facing slopes. The activities are consistent with the 

objectives for OGMAs, but are not consistent with the standard and guideline that indicates 

vegetative management is not allowed.

Alternative 3 
Chapter 2 - Alternatives 

Spears Vegetation Management Project Draft EIS ♦ Page 21 

This alternative was developed to address the purpose and need without the use of commercial 

timber harvest. This alternative focuses on activities that reduce hazardous fuels and the risk of 

stand loss due to high fuel loadings, maintain existing desired fuel levels, increase forested 

stands’ resiliency to insects and disease, and increase growth rates in smaller diameter stands. 

Generally, trees greater than 9 inches dbh would not be cut, except juniper. In isolated cases of 

damaged or diseased trees, trees up to 12 inches dbh would be cut. Maps 7 and 8 display the 

activities proposed in this alternative. 

Appendix A includes a description of the proposed treatments and a table showing the 

prescriptions for each unit included in Alternative 3. 

One Forest Plan amendment is needed to implement this alternative. The plan amendment 

would allow precommercial thinning, hand piling, and underburning in the Stewart Springs 

OGMA. These activities are proposed to improve the longevity of large ponderosa pine on south 

and west facing slopes. The activities are consistent with the objectives for OGMAs, but are not 

consistent with the standard and guideline that indicates vegetative management is not allowed.

Alternative 4 

Alternative 4 was developed based on the road issue discussed in Chapter 1. Alternative 4 

included the objective of minimizing the amount of new road construction. This alternative 

focuses on using existing roads whether open or closed and includes reconstruction. Even 

though this alternative emphasizes use of existing roads, it does include some new road 

construction.

Alternative 5 

Alternative 5 was developed based on the wildlife issue discussed in Chapter 1. This alternative 

includes variable density thinning within some wildlife habitats, and leaving higher densities in 

moister areas such as draw bottoms and RHCAs. Timber harvest and precommercial thinning is 

designed to maintain clumpiness and old tree cohorts within some wildlife habitats. 

This alternative focused on habitats for pileated woodpecker, goshawk, white-headed 

woodpecker, and elk. To address wildlife issues, prescriptions were adjusted to retain habitat 

features for the identified species. Examples of adjusting prescriptions include things such as 

retaining some clumps and defective trees.

Design Elements Common to All Alternatives 

The Forest Service developed the following design elements to be used as part of all of the action 

alternatives. These design elements were developed to reduce the environmental effects of the 

proposed activities or to comply with standards and guidelines in the Forest Plan. Many of the 

design elements for RHCAs and Water Quality/Fisheries are intended to meet the requirements 

for protection of water quality in the State of Oregon through planning, application, and 

monitoring of Best Management Practices (BMPs). 

Air Quality/Private Land Interface 

 Use signing and public notice when burning during hunting season or other times when 

public use of the area is high. To help ensure public safety during burning operations, signs or 
Chapter 2 - Alternatives 

Spears Vegetation Management Project Draft EIS ♦ Page 26 

other traffic control measures would be used in accordance with Oregon Department of 

Transportation permit requirements. 

 All prescribed burning operations would be coordinated with the Oregon State 

Department of Environmental Quality and the Oregon State Department of Forestry through 

FASTRACS, the State of Oregon smoke management program. Anticipated weather conditions 

would be favorable for smoke dispersion. 

 Burn areas adjacent to private land will be patrolled before leaving the site following 

ignition and daily thereafter until the unit fire management officer determines there is no further 

threat to private land. 

 Hazard trees along private land boundaries, created by underburning activities, will be 

felled and left on site. 

 Private landowners within the project area will be notified approximately 14 days in 

advance of any burning activities adjacent to their lands. 

Cultural Resources 

 If a cultural/heritage resource site were discovered or disturbed during implementation, 

efforts would be made to avoid any further disturbance. Site-specific mitigation would be 

determined if sites may not be avoided, and consultation with the Oregon State Historic 

Preservation Office (SHPO) would occur prior to resuming activities. 

Summit Historic Trail 

 Protect the existing historic qualities and features, such as blazed trees, along the Summit 

Historic Trail and Road 27. These areas will be managed within a general border of 600 feet 

either side of the edge of the road or trail and provide a natural setting within the foreground 

area. Unit 751 is within Summit Trail visual partial retention and visual retention designation. 

Unit 752 is within visual retention designation. Units 748 and 742 are adjacent to the Summit 

Trail visual retention corridor boundary. The District Archaeologist will assist with layout of 

Units 738, 740, 751, 752, and 776. 

 Do not post boundary tags on Road 27 and Road 2630 within the Summit Historic Trail 

Management Area. This includes boundary tags for commercial harvest and precommercial 

thinning units. Within retention and partial retention areas (600 feet either side of the Roads 27 

and 2630) in Units 502, 508, 510, 514, 544, 552, 745, 751, 752, 893, 904, and 905 remove 

boundary tags when the contract is completed. 

 In Units 751 and 752, consider yarding tops attached to landings outside visual corridor 

and foreground area to reduce fuel loadings. Use slash to cover/disguise stumps within 75 feet 

of Road 27. 
Chapter 2 - Alternatives 

Spears Vegetation Management Project Draft EIS ♦ Page 27 

 Paint trees for removal in Units 742, 748, 751, and 752. If trees are not harvested, repaint trees so blue marking paint is not visible. 

 Do not use or construct landings within 600 feet either side of Road 27 and Road 2630 

within the Summit Historic Trail Management Area. Exceptions can be made on a case-by-case 

basis, if landings would not be visible in the foreground area because of natural topographic 

features. This applies to Units 742, 748, 751, and 752. 

 Hand pile slash in foreground retention areas along Road 27. This applies to Units 742, 

748, 751, and 752. 

 Do not skid or land along trail route in Units 751 and 752. 

 Minimize new road construction off Road 27. Any newly constructed roads would be 

closed after use. Road closure activities would include activities to conceal locations such as 

covering with vegetation or woody debris. This applies to Units 742, 748, 751, and 752. 

 During precommercial thinning activities in Units 751 and 752, transition thinning to 

blend with adjacent stand conditions. Leave clumps of small trees. 

 For precommercial thinning activities, stumps would not exceed 8 inches in height. Slash 

may be lopped and scattered or piled. Where slash is piled, piles would be small (2-3 feet tall by 

4-feet wide). Burn slash or piles within 1 year if possible. This applies to precommercial thin 

Units 508, 510, 514, 544, and 893 and aspen Units 502, 552, and 745. Retain clumps in 

foreground areas to reduce visual impacts and blend treatments with adjacent areas. 

 Hazard trees will be felled along Road 27. If hazard trees contain blazes, the tree would 

be cut above the blaze. This applies to Unit 751 and 752. 

 Protect historic qualities in and adjacent to Units 738, 740, and 776 which are along the 

stock driveway segment (alternate route for Summit Trail). Minimize the number of skid trails 

that cross the stock driveway segment to no more than three per mile. Do not use or create 

landings within 150 feet of stock driveway segment. Do not post boundary within 25 feet of 

stock driveway segment. 

 Retain carved aspen and protect log troughs. Carved aspen is known to occur Units 104, 

402, 403, 407, 409, 502, 533, 745, 905, and 908. 
Chapter 2 - Alternatives 

Spears Vegetation Management Project Draft EIS ♦ Page 28 

Noxious Weeds 

 Conduct a weed identification workshop for Forest Service personnel who would be 

preparing, implementing, and/or administering the proposed activities. 

 Re-use of landings infested with noxious weeds would not occur, shade would be 

retained, and burning would be avoided within 100 feet of the infestation. Use timber sale 

contract provision CT5.12 (use of roads by purchaser) and CT6.315 (sale operation schedule). 

Units associated with infestations include 110, 306, 317, 542, 544, 559, 707, 803, 819, 841, 844, 

859, 894, 895, 896, 897, 899, 941, 945, and 961. Exceptions may be made through coordination 

with the district weed coordinator. 

 Avoid or minimize disturbance within or adjacent to existing noxious weed infestations 

or develop a control plan to prevent their expansion. For example, avoid using weed-infested 

areas for camps, staging areas, landings, or parking areas. Exceptions may be made through 

coordination with the district weed coordinator. 

 Avoid grapple or hand piling of slash within 200 feet of U.S. Highway 26 and the first 

1/4-mile from the junction of roads connected to U.S. Highway 26. Along Forest Road 2610 this 

criteria extends for the first 1/2-mile. This applies to Units 107, 108, 110, 211, 306, 502, 520, 

567, 568, 700, 707, 708, 722, 734, 740, 741, 814, 815, 818, 819, 828, 832, 833, 838, 840, 841, 

842, 844, 850, 874, 886, 900, 921, 922, and 967. This does not apply to the thinning of conifers 

in Unit 507, an aspen treatment unit. Exceptions proposed to address risk adjacent to private 

land will be coordinated through the District Botanist. 

 Water for prescribed fire control, watering roads, or other activities would be obtained 

from weed-free sites. 

 To reduce the potential for weed spread through mineral material (i.e. gravel and rock) 

used on roads and landings, Ochoco NF material sources will be inspected to ensure materials 

are weed free. Additionally, the sale contract would include provisions requiring any material 

from other sources is weed free. 

 To reduce the potential for transport or spread of noxious weeds by road construction or 

logging equipment, the timber sale contract would include CT6.343 (Opt.2) provision. This 

provision requires: (1) certification that equipment be clean of all plant or soil material that may 

result in the establishment or spread of noxious weeds; and (2) Notification of location where 

equipment was most recently used. The Forest Service Timber Sale Administrator would certify 

that equipment is clean of plant and soil material before the equipment enters the project area. 

 Revegetate roads that will be closed or decommissioned, primary skid trails, and log 

landing areas as part of the final sale contract work. Seeds that are used to revegetate areas 

would be certified as “All States Noxious Weed Free” by an approved testing laboratory, such as 

the Oregon State University Seed Lab. If available, use source-identified, locally-collected 

native grass species including pinegrass (Calamagrostis rubescens), squirreltail (Elymus 

elymoides), Sandberg bluegrass (Poa secunda), basin wildrye (Leymus cinereus), blue wildrye 
Chapter 2 - Alternatives 

Spears Vegetation Management Project Draft EIS ♦ Page 29 

(Elymus glaucus), or native cultivars such as red fescue (Festuca rubra) and big bluegrass (Poa 

ampla). Seed mixture would be applied at approximately 10 lbs/acre. 

 Document all noxious weed infestations identified during implementation by notifying 

the district noxious weed coordinator. 

 Include a noxious weed locator map in the project file to assist in avoidance and 

monitoring. 

 Conduct pre-project surveys to document existing infestations of noxious weeds. 

 Road closures would be coordinated with the district noxious weed coordinator to ensure 

that noxious weed sites are inventoried. 

 Where feasible, retain desirable vegetation on road shoulders, cuts, fills, ditches, and 

drainages. 

 Straw materials that are used in sediment traps will be certified weed-free or be acquired 

from certified fields that produce weed-free seed for the grain or grass seed industry. 

Range/Minerals 

 Livestock fences, cattle guards, and other structural range improvements would be 

protected and/or returned to their pre-activity condition if damaged during thinning or burning 

operations. 

 Logging, burning, and road closure activities would be coordinated with 

permittees/mining claimants as needed. Efforts will be made to minimize conflicts between 

livestock use/mining activities and logging, thinning, and burning activities. 

Recreation 

 Restrict commercial timber haul on holiday weekends (i.e., Memorial Day, 4th of July, 

Labor Day) and during the weekends of deer and elk rifle hunting season. Restrict use from 

Thursday noon through Monday noon. Also restrict commercial timber haul on the day before 

opening of deer rifle season. 

 Activities adjacent to management allocated dispersed recreation sites will be designed to 

retain visual screening. Also activity-generated slash within 25 feet of dispersed sites that is 

useable as firewood will be stacked. This applies to Units 137, 184, 210, 306, 401, 512, 707, 

718, 719, 723, 737, 751, 752, 812, 821, 850, 851, 863, 867, 873, 901, 922, 947, 949, and 972. 

 Avoid utilizing management allocated dispersed recreation sites for log decks, piling 

slash, storing road rock, or dumping borrow material. This applies to Units 179, 184, 210, 306, 

524, 707, 718, 751, 752, 821, 851, and 863. 
Chapter 2 - Alternatives 

Spears Vegetation Management Project Draft EIS ♦ Page 30 

 Avoid allowing industrial (contractor) camps at management allocated dispersed 

campsites. This applies to Units 137, 179, 184, 210, 306, 307, 501, 512, 538, 550, 552, 700, 707, 

718, 719, 723, 812, 821, 851, 860, 862, 863, 867, 873, 876, 893, 901, 922, 947, and 949. 

 After timber harvest activities are complete, disturbed sections of system trails would be 

reconstructed to the existing (pre-harvest) condition within 2 months of activity or funds would 

be collected for reconstruction. This includes replacing any trail markers that are removed as a 

result of timber harvest activities and roads that are reopened. 

 Commercial harvest, thinning, and burning activities would be coordinated with special 

use permit holders or their representatives, as needed. Efforts would be made to minimize 

conflicts between recreation permittees and commercial harvest, thinning, and burning activities. 

 Along trails, where the trail is the boundary, avoid “straight line” burning by using 

methods such as discontinuous ignition. The objective is to have mosaic burns with low scorch 

height on trees. This restriction applies to Units 172, 199, 200, 201, 214, 738, 739, 740, 741, 

743, 744, 772, and 776. 

Bandit Springs Nordic Trail System

 Commercial timber harvest activities would be restricted between December 1 and March 

30. Activity-generated slash would be cleared prior to the ski season for a minimum of 10 feet 

on each side of trails (for a minimum width of 20 feet). This restriction applies to Units 738, 

740, 742, 748, 751, 752, and 776. 

 Noncommercial activities adjacent to trails would be restricted and trails cleared of 

activity-generated slash between December 1 and March 30. Slash would be cleared prior to the 

ski season for a minimum of 10 feet on each side of trails (for a minimum width of 20 feet). 

Clear slash as soon as activity is finished or at least prior to the ski season. This restriction 

applies to Units 739, 743, 744, 747, 772, and 885. 

 Landings would not be located on system trails. This applies to Units 738, 740, 742, 751, 

752, and 776. 

 Avoid locating grapple piles within 100 feet of system trails. This applies to Units 738, 

740, 742, 748, 751, 752, and 776. 

 To reduce the time that management activities in Unit 740 are apparent, grapple piles will 

be removed or burned by December 1 of the year following the piling activity. 

 To minimize the intensity of underburning, perform a spring burn on Unit 741. 

 Prescribed fire would not be ignited within 50 feet of each side of system trails when the 

trail is inside a burn unit. This applies to Units 738, 739, 740, 741, 742, 747, 751, 752, and 900. 
Chapter 2 - Alternatives 

Spears Vegetation Management Project Draft EIS ♦ Page 31 

 Along system trails, if trees containing blue or orange diamond or other trail markers are 

marked to be cut, the trail markers would be moved to a nearby tree at the time the tree is marked 

for removal. System trails occur in Units 736, 739, 740, 742, 743, 751, 752, 772, and 776. 

 Boundary tags, markers, and flagging would be removed after completion of post-sale 

activities along all system trails. 

 Feather edges around ski trails and trail corridors. Avoid geometric shapes and lines not 

in character with the existing landscape. Activities are designed to appear as a natural 

occurrence when viewed in the Foreground. This applies to Units 738, 739, 740, 742, 743, 751, 

752, 772, and 776. 

 Informative signs will be posted at Bandit Springs Rest Area, trailheads, and access 

points prior to activities occurring in this area. 

Ochoco Divide Sno-Park, Road 27, and Road 2630 snowmobile routes 

 Commercial timber harvest activities would be restricted on weekends (Friday noon to 

Monday noon) between December 1 and March 30. The sale administrator may waive this 

seasonal restriction only when there is no snow. 

 Restrict commercial timber haul on the Snow Park Tie Trail and the Marks CreekIndependence Mine Snowmobile Trails (Roads 2630 and 2630-013) on weekends (Friday noon 

to Monday noon) between December 1 and March 30. The sale administrator may waive this 

seasonal restriction only when there is no snow. 

 Landings would not be located on system trails. This applies to Units 509 and 888. 

 Informative signs will be posted at Ochoco Divide Campground, Ochoco Sno-Park, 

Marks Creek Sno-Park, and Walton Lake Sno-Park prior to activity. 

Corral Flat Dispersed Camping Area 

 All slash would be removed from the permitted horse trails 2 weeks prior to the annual 

endurance ride. The annual endurance ride usually occurs during the third weekend in July. 

This activity applies to Units 303, 304, 514, 524, 530, 531, 532, 550, 560, and 893. 

 Commercial harvest operations would be restricted for 3 weeks (end of June-July) each 

year during the annual endurance ride. There would be a commercial harvest restriction within 

1/4-mile of the endurance ride trail that begins the Wednesday before each endurance ride and 

continues until the Tuesday following the event. This seasonal restriction applies to Units 303, 

304, 524, 530, 531, 532, 550, and 560. 
Chapter 2 - Alternatives 

Spears Vegetation Management Project Draft EIS ♦ Page 32 

Walton Lake Nordic Ski Trail System 

 Activities adjacent to trails would be restricted between December 1 and March 30. 

Slash would be cleared prior to the ski season for a minimum of 10 feet on each side of trails (for 

a minimum of 20 feet). Clear slash as soon as activity is finished or at least prior to the ski 

season. This restriction applies to Units 544 and 546. 

 Landings would not be located on system trails. This applies to Unit 546. 

Wildcat Trail # 833 

 After timber harvest activities are complete, disturbed sections of system trails would be 

reconstructed to the existing (pre-harvest) condition within 2 months of activity or funds would 

be collected for reconstruction. This includes replacing any trail markers that are removed as a 

result of management activities. Slash would be cleared from the trail for a minimum of 10 feet 

on each side. Prohibit grapple piling within 100 feet of trails. This applies to Units 172, 199, 

200, 201, and 214. 

 Landings would not be located on system trails. This applies to Units 166, 172, 199, 200, 

and 201. 

RHCAs 

 No machine (i.e. bulldozer) fire lines would be constructed within RHCAs. 

 Hand fire lines would not be constructed within 10 feet of a Class IV stream or within 20 

feet of Class I, II, or III streams. Hand fire line would not be constructed through seeps, bogs, 

springs, meadows, and any other wet area. 

 Fire prescriptions for RHCAs would provide for a mosaic of burned and unburned 

material to retain vegetation for infiltration. 

 To meet mosaic and intensity objectives, fire may be purposely ignited within RHCAs. 

Prescribed fires would not be ignited within 50 feet of a stream. 

 Avoid locating industrial camps in RHCAs. 

 Precommercial thinning would not cause a reduction in shade on perennial streams (Class 

I, II, and III) with the exception of thinning to promote deciduous trees and shrubs. Thinning 

around hardwoods would be coordinated with the fisheries biologist or hydrologist. 

 Thinning and burning activities would not remove vegetation that is contributing to bank 

stability, especially in those areas adjacent to dormant or active landslide terrain. 
Chapter 2 - Alternatives 

Spears Vegetation Management Project Draft EIS ♦ Page 33 

 Within RHCAs, effective ground cover would be established on landings and skid trails 

used for logging operations and on decommissioned and temporary roads. When consistent with 

other management actions, slash would be used on skid trails, temporary roads, and roads 

proposed to be closed. This would be done in conjunction with post-haul treatments when 

timber harvest is completed. 

 Hazard trees within RHCAs, which are required to be felled, would be left on site or 

managed for the attainment of RMOs for in-stream large wood recruitment. 

 There will be no new landings within RHCAs and ephemeral draws. Existing landings 

may be reused. Reuse of existing landings within RHCAs will be coordinated with the fisheries 

biologist or hydrologist. 

 To reduce ground-disturbance within RHCAs, ground-based machinery for logging or 

slash piling operations would not be used within RHCAs, including areas around springs, except 

on existing roads. Other exceptions would be evaluated on a case-by-case basis with the 

hydrologist or fisheries biologist. Exceptions include: 

 1. Pulling cable (winch lining) from an existing road in an RHCA.

 2. Using existing roads as landings in RHCAs, such as in Units 104, 117 and 559. 

 3. Constructing spur roads to access landings within units, such as Units 112 and 118. 

Landings will be located outside RHCA. 

 Within Class IV RHCAs, no commercial harvest would occur within 25 feet of the 

stream bank to reduce potential sediment delivery 

 To maintain shade and stream bank stability, commercial harvest within Class I, II, and 

III RHCAs would only occur in the outer 100 feet of the RHCAs. 

 To reduce ground-disturbance within RHCAs during precommercial thinning and 

burning operations, off-highway or all-terrain vehicles would not be operated within RHCAs or 

on closed roads within RHCAs. 

Sensitive Plants 

 Areas would be designated to protect habitat for yellow lady’s slipper orchid 

(Cypripedium parviflorum). Slash piling and underburning would be avoided in these areas. 

Units that contain potential yellow lady’s slipper (moist grand fir) habitat would be reviewed 

prior to implementation. Potential yellow lady’s slipper habitat occurs in Units 163, 199, 515, 

526, 542, 546, 707, 738, 748, 751, 823, 824, 845, 846, 869, 870, 872, 889, 932, 942, 959, and 

982. 

 To protect sensitive species associated with riparian areas, no ground-based equipment, 

including grapple pilers, would be used within 100 feet of areas identified as containing Peck’s 

lily (Calochortus longebarbatus var. peckii) populations or habitat. Exceptions can occur on 

existing roads and crossings, or other areas that have been reviewed by the botanist. Potential 
Chapter 2 - Alternatives 

Spears Vegetation Management Project Draft EIS ♦ Page 34 

habitat for Peck’s lily occurs in or near Units 120, 148, 302, 303, 407, 408, 409, 501, 502, 503, 

512, 513, 514, 521, 524, 532, 538, 552, 560, 562, 565, 567, 568, 569, 704, 741, 744, 734, 742, 

747, 748, 867, 888, 907, 913, 914, 921, 922, 923, 925, 980, and 981. 

 Vehicles, including off-highway or all-terrain vehicles, will not be operated within areas 

identified as Peck’s lily habitat, except on existing roads. 

 To reduce impacts to scabland habitat (lithosol soils), and associated sensitive ricegrass 

(Achnatherum hendersonii and A. wallowaensis) habitat, construction of temporary roads or 

landings on scabland habitats would not occur. Scabland habitats occur within Units 111, 112, 

117, and 806. 

 Avoid ground-disturbing activities, including piling of slash, on scablands. Vehicles, 

including off-highway or all-terrain vehicles, will not be operated on scablands. Exceptions can 

occur on existing roads, or other areas that have been reviewed by the botanist. 

Soils 

 For tractor logging units, the leading end of logs would be suspended where practical 

during skidding to limit soil displacement. Ground-based equipment would not be operated on 

slopes greater than 35 percent in tractor units. Winch lining will be required on slopes greater 

than 35 percent to minimize detrimental impacts. 

 Skid trails would be designated and approved prior to logging and would be located on 

already disturbed areas where possible. Where practical, skid trails would avoid ephemeral 

draws and scablands. Where not practical, skidding would be perpendicular to ephemeral draws. 

Skid trails, landings, and roads would be designed to limit the cumulative extent of activities. 

 After harvest and grapple piling activities are completed, soil monitoring will evaluate 

the need for soil rehabilitation, such as tilling. Soil rehabilitation is expected to occur in Units 

107, 111, 114, 120, 125, 127, 139, 143, 160, 162, 163, 166, 173, 176, 181, 198, 300, 301, 302, 

310, 311, 317, 509, 515, 524, 531, 532, 550, 559, 560, 563, 565, 569, 570, 572, 700, 705, 707, 

711, 718, 729, 734, 738, 740, 742, 751, 752, 811, 815, 821, 824, 825, 831, 836, 846, 848, 858, 

859, 863, 865, 869, 878, 888, 891, 986, and 988. 

 Grapple pilers would be limited to operating on existing compacted/displaced areas to 

limit the amount of detrimental soil conditions. In undisturbed areas, grapple pile equipment 

would be allowed to make 1-2 passes to move between skid trails and other detrimentally 

disturbed areas. Grapple pilers would be limited to slopes less than 35 percent. 

 In units where detrimental soil conditions occur on less than 20 percent of the area, 

design activities so that detrimental soil conditions do not exceed 20 percent. This includes 

designating skid trails, landings, and roads. 

 In units where detrimental soil conditions exceed 20 percent of the area, if tillable, allow 

no more than 5 percent increase over existing conditions and then till so that there is no net 
Chapter 2 - Alternatives 

Spears Vegetation Management Project Draft EIS ♦ Page 35 

increase in the percentage of detrimental soil conditions. If tillage is not feasible, stay on 

existing disturbed areas and allow no increase in detrimental soil conditions. 

Visual/Scenic Resources 

 Boundary tags, flagging, and markers would be removed from harvest units in foreground 

retention areas after completion of activities to minimize visibility. Foreground retention areas 

include the U.S. Highway 26 corridor, corridors along Roads 27 and 2630, and portions of Road 

2210, and the Bandit Springs Recreation Area. This applies to Units 108, 110, 148, 509, 542, 

550, 559, 564, 700, 707, 734, 740, 742, 748, 751, 752, 814, 815, 817, 841, 851, 887, and 888. 

 In Foreground retention areas, trees within 75 feet of the primary travel corridor would be 

cut to minimize stump heights. For commercial timber harvest, stumps would not exceed 6 

inches in height. For precommercial thinning activities, stumps would not exceed 8 inches in 

height. Primary travel corridors include U.S. Highway 26, Road 27, Road 2630, and portions of 

Road 2210, and designated trails (including trails in the Bandit Springs Recreation Area). This 

applies to Units 108, 110, 148, 211, 509, 510, 514, 542, 550, 555, 559, 564, 567, 568, 700, 707, 

708, 722, 734, 740, 742, 748, 751, 752, 814, 815, 817, 818, 819, 828, 840, 841, 844, 851, 874, 

887, 888, 893, 896, and 981. Along Road 27 which is the Summit Historic Trail, minimize 

stump heights within 300 feet of road; this applies to Units 751 and 752. 

 In Foreground retention areas, where practical, design and locate new skid trails and 

landings at least 300 feet from primary travel corridors. Landings would be revegetated within 1 

year of use. Primary travel corridors include U.S. Highway 26, Roads 27 and 2630, and portions 

of Road 2210. This applies to Units 108, 110, 148, 509, 542, 550, 559, 564, 700, 707, 734, 740, 

742, 748, 751, 752, 814, 815, 817, 841, 851, 887, and 888. 

 To reduce long-term visual effects in Visual Corridors, tree marking paint would be used 

to designate trees to be harvested, rather than trees to be retained. This applies to Units 108, 110,

148, 509, 542, 550, 559, 564, 700, 707, 734, 740, 742, 748, 751, 752, 814, 815, 817, 841, 851, 

887, and 888. 

 Underburning activities in the Foreground retention areas would be designed to avoid 

scorching more than 1/3 of the live crown of dominant and codominant trees. Activities such as 

pruning of lower branches may be used to guard against high crown fire if necessary. 

Foreground retention areas include primary travel corridors along U.S. Highway 26, Roads 27 

and 2630, and portions of Road 2210. This applies to Units 501, 512, 520, 538, 741, 747, 833, 

838, 842, 886, 900, 901, 921, 922, and 923. 

Water Quality/Fisheries 

 New roads will be closed or decommissioned in accordance with District written 

guidelines for “Road Closure and Decommissioning” when harvest operations are completed, 

except when otherwise designated. The purpose of closing and/or decommissioning roads is to 

eliminate motorized travel, provide long-term drainage, and reduce erosion potential to speed 

recovery. 
Chapter 2 - Alternatives 

Spears Vegetation Management Project Draft EIS ♦ Page 36 

 Newly constructed roads within RHCAs would not parallel streams. 

 Seeps, springs, and landslide areas would be managed using Class III and IV RHCAs as 

specified in INFISH. 

 Skid trails and temporary roads within 50 feet of the scab-conifer interface, that are used 

during harvest operations, would be designed to reduce the concentration of flows and to 

encourage the flow of water off of them. This applies to Unit 111.

 Streams requiring classification or reclassification would be coordinated through the 

hydrologist or fisheries biologist prior to marking. 

 To maintain ground cover and reduce potential sediment delivery, natural fuels 

(underburning) activities in the Wildcat and Salmon Creek subdrainages would occur at least 1 

year before or 3 years after commercial timber harvest. This applies to Units 137, 804, 805, 823, 

928, and 961. 

 Landings used in harvest operations would be scarified and seeded to increase infiltration 

and prevent surface erosion. Landings that are located on a gravel road or at turnouts that will 

remain open to traffic use would be exempt from the scarification and seeding requirements. 

 Dust abatement on haul roads would occur to reduce sediment (i.e. dust) entering 

streams. Generally, this means haul roads within RHCAs. Water used for dust abatement would 

be obtained from sources identified in the May 1996 Ochoco National Forest Water 

Conservation Plan. 

 Newly constructed and reconstructed roads with stream crossings would have adequate 

relief drainage installed prior to runoff reaching the stream channel. Filter strips below drainage 

structures would be of sufficient size to catch sediment before runoff enters streams. If adequate 

filter strips are not available, slash, straw material, rock aprons, or other filtering structures 

would be installed. Stream crossings structures (culverts and fords) on Class IV streams would 

be installed when the channel is dry. 

 In channel work on Class I-III streams would be accomplished in accordance with 

“Oregon Guidelines for Timing of in-Water Work to protect Fish and Wildlife Resources, June 

2000.” For the Spears project area, the timing for in-water work is July 1 to October 31. 

 Relief drainage/erosion control devices, such as straw material or sediment traps, would 

be placed at designated road/stream crossings to reduce sediment delivery to streams. The 

fisheries biologist or hydrologist will coordinate specifications and locations. 

 During wet periods, commercial road use will not contribute to siltation outside the 

roadway. For example, suspension of use may occur when road use is contributing to sediment 

detachment and transport, i.e. rutting 1 - 2 inches deep, muddy ditch water.

Wildlife 

Goshawk 

 A 400-acre post fledging area (PFA) has been established around each known nest site. 

Commercial harvest operations, precommercial thinning, and underburning within PFAs would 

occur during the period September 1 through February 28. No management activities, including 

underburning activities, would occur inside the 30-acre nest stand. 

 There would be a seasonal restriction (March 1 to August 31) on commercial harvest, 

precommercial thinning, and underburning within approximately 1/2-mile of an active nest. This 

may also be applied to hauling operations if nests are within the immediate proximity of the haul 

route. This seasonal restriction may be waived on an annual basis if a nest inventory determines 

that breeding is not active. This restriction applies to Units 302, 303, 401, 722, 723, 727, 729, 

734, 815, 816, 818, 819, 858, 860, 861, 867, 903, 919, 934, 949, and 984. 

Other Raptors 

 Nest Sites - For the primary zone within 330 feet of nest site, maintain existing habitat 

characteristics. For the secondary zone (between 330 and 660 feet) around a nest site, modified 

treatments are permitted. Modified treatments are intermediate treatments between that required 

in the primary zone and that normally prescribed outside the whole protection zone. Operations 

would be restricted for both primary and secondary zones between March 1 and August 1. 

Underburning would not be allowed within 330 feet of the nest site. This seasonal restriction 

may be waived on an annual basis if a nest inventory determines that breeding is not active. This 

seasonal restriction applies to Units 148, 177, 211, 212, 303, 304, 401, 402, 559, 560, 719, 722, 

723, 729, 874, 875, 934, 952, 955, and 962. 

Osprey: There would be a seasonal restriction (March 1 to August 1) on commercial 

harvest, precommercial thinning, and underburning within 1/4-mile of osprey nests. This 

seasonal restriction may be waived on an annual basis if a nest inventory determines that 

breeding is not active. This restriction applies to Units 401, 559, 719, 722, 723, 729, 874, 875, 

and 955. 

Deer and Elk 

 Activities involving heavy/power equipment would not be allowed within big game 

winter range areas from December 1 through May 1, unless coordinated through the wildlife 

biologist. This seasonal restriction applies to Units 100, 101, 104, 105, 106, 111, 112, 115, 117, 

139, 142, 143, 148, 155, 202, 207, 212, 311, 315, 806, 809, 814, 820, 825, 826, 831, 834, 836,

Snags/Down Logs 

 Snags that pose a safety hazard would be felled. Within RHCAs, they would be left on 

site or managed for in-stream large wood. 

 Harvest activities would not remove existing down logs. Fuel reduction activities would 

be designed to minimize loss of large down wood. This includes no direct ignition of large down 

wood, briefing of burn crews to emphasize burn objectives, and burning under conditions which 

make large fuels unavailable for consumption. Down logs are defined as logs that are 12 inches 

or greater at the small end and greater than 6 feet in length. 

 Burning within goshawk post-fledging areas, pileated feeding habitat, and connective 

corridors would be coordinated with the wildlife biologist. 

Monitoring 

Conduct post-project surveys and monitoring of noxious weed infestations, including mineral 

material sources, to evaluate the effects of the project on noxious weeds. Post-project surveys 

would identify new noxious weed infestations while they are small. 

Temperature monitoring will continue on selected stream reaches such as Marks, Salmon, and 

Little Hay Creeks. 

Pre and post-activity shade monitoring will be accomplished on at least one aspen stand where 

thinning is scheduled. 

Two water quality monitoring stations have been established in the Marks Creek Watershed: 

Marks Creek above Little Hay Creek and Wildcat Creek above U.S. Highway 26. Discharge, 

TSS (total suspended solids), and turbidity will be measured.

CHAPTER 3. AFFECTED ENVIRONMENT AND 

ENVIRONMENTAL CONSEQUENCES 

This chapter summarizes the physical, biological, social, and economic environments of the 

project area and the effects of implementing each alternative on that environment. It also 

presents the scientific and analytical basis for the comparison of alternatives presented in the 

alternatives chapter. 

The information in this chapter summarizes the affected environment, direct, indirect, and 

cumulative effects of the alternatives along with conclusions and supporting rationale. Further 

information on the specifics of the affected resources such as historical conditions, assumptions, 

methodologies, analyses, specific localized information, references, and technical documentation 

can be found in the individual specialists’ reports in the project record. 

Late and Old Structure (LOS) 

Affected Environment 

The upland forest areas within the Spears project area have been characterized using the plant 

association concept. Plant associations are a method of land classification which is based on the 

probable, or projected, plant community which will occupy a site given enough time and an 

absence of disturbance influences. The plant associations for the entire Ochoco National Forest 

have been mapped using the classifications described in “Plant Associations of the Blue and 

Ochoco Mountains” (Johnson and Clausnitzer 1992). The mapping was based on 1:12000 aerial 

photography and intensive fieldwork. In 1998, the adjacent private lands within the Marks Creek 

watershed were mapped using 1:16000 aerial photos. 

The Ochoco National Forest has defined eight plant association groups (PAGs) for upland forest 

and woodland sites. These groups contain plant associations of similar biophysical 

environments, productivity, and disturbance regimes. Six PAGs occur within the Spears project 

area. There are approximately 4,600 acres of nonforest area within the project area.

Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 45 

The Ochoco National Forest’s Viable Ecosystem Management Guide (Simpson et al. 1994) 

describes a seral/structural matrix for characterizing forest vegetation within each of the PAGs. 

The Ochoco NF matrix has three seral stages based on species composition (early, mid, late), and 

each of these is subdivided into five size/structural conditions (grass/forb/shrub, seedling/sapling, 

pole, small trees, large trees). Thus, the matrix can accommodate up to fifteen cells. The 

grass/forb/shrub condition is only reflected in the early seral condition. Matrix cells are further 

subdivided to reflect relative differences in tree density, subscripts “a” and “b” are used to denote 

high and low density, respectively. For example, L4a describes a late-seral species composition, 

small-sized trees, at a high-density level. An example matrix is shown below: 

Table 7. Viable Ecosystem seral/structural matrix.

Structure Class Species Composition 

Early Mid Late 

Grass, forb, shrub (trees may be present but not dominant) E1 -- -- 

Seedling, sapling (less than 4.9 inches dbh) E2 M2 L2 

Pole (between 5 and 8.9 inches dbh), high density E3a M3a L3a 

Pole, low density E3b M3b L3b 

Small (between 9 and 20.9 inches dbh), high density E4a M4a L4a 

Small, low density E4b M4b L4b 

Medium/large (21 inches dbh and larger), high density E5a M5a L5a 

Medium/large, low density E5b M5b L5b 

Satellite imagery from 1999, updated to 2004 through change detection analysis, has been used 

to determine the current distribution of seral structural stages. The resolution of the satellite 

imagery is approximately 1/6th of an acre. Each 1/6 acre is assigned to one of the VEMG matrix 

classifications depending upon species composition, structure, and density. Stand growth and 

disturbance since 2004 that changed vegetative stages has not been included. These changes 

would include slightly increased canopy closure due to ingrowth and expanded conifer 

dominance on sites identified as grass, shrub, and forb (E1). They would also include mortality 

due to insects and disease, resulting in an increase in the E1 condition. The amount of change 

since 2004 is so small that it would not meaningfully alter the analysis. The effects of past 

harvest, fire, and mortality were incorporated into the 2004 satellite analysis. 

The Viable Ecosystem model has been used to characterize the existing landscape and to provide 

a means of comparison to historical conditions. Five of the six PAGs have been fully analyzed 

for the project area. A range of acres for each stage is given to compare the current conditions to 

conditions found in the area historically. The existing condition of the western juniper PAG is 

displayed but effects on the alternatives on this PAG were not analyzed because the number of 

acres treated is small, and mostly consists of underburning which would have little if any effect 

on the vegetative stages. Tables 8 through 13 display the existing condition and the historic 

range of variability (HRV) for all six PAGs in the project area.

LOS is an important vegetative condition specifically identified in the Regional Forester’s Forest 

Plan Amendment No. 2 (June 1995). This Forest Plan amendment is commonly referred to as 

the Eastside Screens. The Eastside Screens define LOS as vegetative structures in which large 

trees are a common feature. It goes on to identify two different structural conditions, multi and 

single strata. 

Satellite imagery is used as the landscape analysis tool to estimate the existing amount of LOS. 

The Viable Ecosystem size/structure class 5 (21 inch or greater dbh) is used to identify existing 

LOS. Differentiation between multi- and single-strata LOS is based on the “a” and “b” density 

classifications. The amount of each LOS type by PAG was compared to its corresponding HRV. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 48 

Currently, the project area contains an estimated 5,575 acres of LOS. Most of the LOS, about 

3,960 acres, is in a multi-strata condition. Historically, the overall amount of LOS would have 

ranged between 10,569 and 20,205 acres. Historically, most of the LOS would have been single 

strata due to the frequent low-intensity fires which were the dominate disturbance regime in the 

area. Examination of each PAG reveals that all PAGs are within or above the historic range for 

the multi-strata condition. All PAGs except moist grand fir are below the historic range for the 

single-strata condition. The moist grand fir PAG is within the range for the single-strata 

condition. The moist grand fir PAG was historically influenced by more infrequent, higherseverity fires which are reflected in the historic ranges. Across all PAGs, the total amount of 

multi-strata LOS is within the combined historic ranges, while single-strata LOS is below.

The information displayed in Table 14 includes all LOS stages within the project area, regardless 

of patch size. The Ochoco NF has identified a minimum patch size of 5 acres that must be met 

in order to qualify as an LOS “stand” as described in the Eastside Screens. (The April 6, 2007, 

Silvicultural Input for this project includes additional information.) 

Environmental Consequences 

Successional and structural changes as a result of the alternatives and projections through time 

were estimated using the Viable Ecosystem model. This model accounts for multi-directional 

change (multiple pathway succession) through time, but does not include future disturbances. 

The model does include density-dependent growth effects. The fuels reduction activities have 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 49 

not been incorporated into the projections because the effects of these activities are not 

anticipated to create changes in species composition, structure, or density of a magnitude large 

enough to be measured. 

There are two primary processes that affect the movement of one seral structural stage to 

another. Species composition changes due to succession tend to favor shade-tolerant species and 

move stages from early seral to late seral. Growth moves stages from smaller to larger structural 

stages. Although some insects and disease disturbances are species specific and can move early 

seral to mid or late seral, natural disturbance processes (including fire, insects and diseases, and 

flooding) tend to move stages backward from mid or late seral to early seral. The magnitude of 

movement depends on the intensity of the disturbance. Some disturbances, such as low-intensity 

fire, may not affect the dominant stand character, but serve to maintain the existing stage. 

Differing growth rates were applied to the two density categories (“a” and “b”) within the grand 

fir, Douglas-fir, and ponderosa pine PAGs. These growth rates directly correspond to rates of 

change in structure in the Viable Ecosystem seral/structural stages. Less dense “b” stages 

received an average 20 percent growth rate increase over stands which have high “a” densities. 

This estimate corresponds with density and spacing studies (Oliver 1979, Barrett 1982, Cochran 

and Barrett 1993, and Cochran and Barrett 1999b) where growth rate increases from thinning 

varied between 15-25 percent depending on stand density and little gains were realized when 

canopy closure was not reduced below 50-60 percent.

The projected future abundance of each stage is based on stand development assumptions for the 

various seral structural stages. The 20, 30, and 50-year time intervals were chosen to 

demonstrate development over time. These projections indicate that all action alternatives move 

toward the HRV for the first 20 years. Between 20 and 50 years, the results indicate the action 

alternatives move closer to the HRV than the no action alternative. These projections include 

changes from natural growth and succession, as well as endemic levels of disturbance (insects 

and disease). The projections do not include future disturbance events such as widespread insect 

and disease occurrences, fire, or management activities other than continued fire suppression. 

The action alternatives are designed to reduce tree density and improve growth and vigor of the 

residual trees and reduce susceptibility to insects and disease. Thinning will more quickly 

restore historic seral/structural stage conditions and improve growing conditions for larger trees 

than either no action or prescribed fire alone. Thinning also decreases the probability of crown 

fires, reducing the potential area burned by unwanted fires, and decreases potential fire severity 

(Peterson et al. 2005). 

Live trees 21 inches dbh or larger would not be cut in any prescription except when necessary to 

provide safe working conditions. Hazardous trees that are cut down in Riparian Habitat 

Conservation Areas would be left on site. 

Numerous studies have shown increased growth and vigor of remaining trees following thinning 

(Oliver 1979, Barrett 1981, Barrett 1982, Barrett 1989, Larson et al. 1983, Cochran and Barrett 

1999a, and Cochran and Barrett 1999b). Growth response to thinning has been shown to occur 

in all size classes of trees, including large old ponderosa pine (McDowell et al. 2003). Other 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 50 

studies have shown reduced susceptibility to many insect and diseases that are density related 

(Roth and Barrett 1985 and Filip and Schmidt 1990). Further studies show moderated fire 

hazard and lower crown fire potential as a result of thinning and fuel reduction activities (Omi 

and Martinson 2002 and Pollet and Omi 2002). 

Alternative 1 

LOS development within the project area would be determined by existing stocking and species 

composition. Much of the future LOS that develops through natural growth and succession 

would tend towards mid or late-seral species composition and multi-strata characteristics. These 

conditions are already within or above the historic range for all PAGs. Within 20 years, the total 

amount of multi-strata LOS is projected to exceed the overall historic range for the project area. 

The rate at which stands would develop large tree character would be hampered by over stocked 

conditions. On drier sites, such as the ponderosa pine and Douglas-fir PAGs, stand stagnation 

may preclude the attainment of additional large trees. Existing LOS (i.e. large trees) would 

continue to be susceptible to mortality from competition with understory trees and the 

accompanying increase in risk to loss due to insects, disease, and wildfire. 

Tables 15 through 18 and Figures 1, 2, and 3 below display the predicted amounts of LOS that 

would occur under each alternative. 

Alternative 2 

Activities would generally move stands in a multi-strata condition to or towards a single-strata 

condition. Many stands would continue to be in an uneven-aged condition. Reducing stand 

density would reduce competitive stress on the remaining trees (Powell 1999). This would result 

in more large trees being maintained over time, as well as to encourage the development of 

additional large trees (Cochran et al. 1994). The abundance of early-seral species would be 

maintained and enhanced in the long-term; however, late-seral species would continue to be 

present in stands where they exist prior to treatment. Grand fir and Douglas-fir would be 

retained both in the overstory (all trees >21” dbh) as well as in the understory but in lesser 

amounts. 

Activities are also proposed in single-strata conditions but where stocking density is currently 

considered to be too high. Thinning activities would target the smaller diameter and less 

vigorous trees for removal, while maintaining the generally single-strata characteristics. This 

would encourage the development of large structure at an accelerated rate. In addition, reducing 

stocking density would increase tree vigor and reduce insect and disease hazard. 

Activities would remove understory trees to reduce stand density, to maintain existing large 

trees, and to enhance the development of additional large trees. No live trees 21 inches dbh or 

larger, except those trees considered hazardous to the logging/hauling operation, would be cut. 

Primarily fire-intolerant, late-seral species would be targeted for removal although these species 

would not be eliminated. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 51 

Reducing stand densities would reduce competitive stress. This would result in more large trees 

being maintained over time, as well as encourage the development of additional large trees. 

Activities would also reduce the risk of large tree mortality due to disturbance agents. Singlestrata conditions are more likely to be sustained over time than multi-strata conditions since the 

trees are more vigorous and less susceptible to insects, disease, and wildfire. The abundance of 

early-seral species would be maintained and enhanced in the long term. 

The overall amount of LOS would not change immediately due to treatment, although 929 acres 

of multi-strata LOS would be converted to single-strata LOS. The overall amount of multi-strata 

LOS would not be reduced below historic levels; however, the amount of multi-strata LOS 

within the Douglas-fir PAG would drop below the historic range by 222 acres. By year 20, the 

amount of multi-strata LOS in the Douglas-fir PAG would increase to be within the historic 

range. After year 20, the amount of multi-strata LOS remains within or above the historic range 

for all PAGs. This alternative results in the greatest amount of single-strata LOS in both the long 

and short term, although the overall amount of single strata does not reach the historic range 

within the 50-year projection period. Tables 15 through 18 and Figures 1, 2, and 3 below display 

the predicted amounts of LOS that would occur under each alternative. 

Alternative 3 

Precommercial thinning in this alternative would remove smaller diameter trees and reduce some 

competitive stress on the remaining trees. Early-seral species or disease-resistant trees would be 

selected for retention where possible. Because only small trees would be removed, the amount 

of competition among the remaining trees would vary depending on the existing stand density 

and number of trees greater than 9 inches dbh. In some units, it may not be possible to reach 

recommended stocking levels. Disease in trees larger than 12 inches dbh, such as dwarf 

mistletoe, would not be reduced. The ability to change species dominance from late seral to 

early seral would be limited where there is an abundance of late-seral trees 9 inches dbh and 

larger. In addition, the ability to move from multi-strata conditions to single-strata conditions 

would be reduced where trees in the 9 to 20 inch dbh range make up a separate canopy strata. 

Reducing stand densities would reduce competitive stress although not to the extent possible 

with commercial harvest. Density reduction would result in more large trees being maintained 

over time, as well as encourage the development of additional large trees. Activities would also 

reduce the risk of large tree mortality due to disturbance agents. Single-strata conditions are 

more likely to be sustained over time than multi-strata conditions since the trees are more 

vigorous and less susceptible to wildfire. The abundance of early-seral species would be 

maintained and enhanced in the long term. This alternative would not directly move any acres of 

multi-strata LOS to single-strata LOS. 

The overall amount or distribution of LOS would not change immediately due to thinning. 

Precommercial thinning would tend to maintain LOS in its current condition for a longer period 

of time when compared to Alternative 1. In stands that are currently not LOS, thinning trees less 

than 9 inches dbh would accelerate their growth and allow the development of large trees at a 

faster rate than if they were left unthinned. By year 20, there would be an increase in the amount 

of LOS, but the increase is the least of all the action alternatives. This trend continues through 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 52 

the 50-year projection period. Tables 15 through 18 and Figures 1, 2, and 3 below display the 

predicted amounts of LOS that would occur under each alternative. 

Alternative 4 

Activities would generally move stands in a multi-strata condition to or towards a single-strata 

condition similar to Alternative 2; however, fewer acres would be treated. Many stands would 

continue to be in an uneven-aged condition. Reducing stand density would reduce competitive 

stress on the remaining trees (Powell 1999). This would result in more large trees being 

maintained over time, as well as to encourage the development of additional large trees (Cochran 

et al. 1994). The abundance of early-seral species would be maintained and enhanced in the 

long-term; however, late-seral species would continue to be present in stands where they exist 

prior to treatment. Grand fir and Douglas-fir would be retained both in the overstory (all trees 

>21” dbh) as well as in the understory but at lesser amounts. 

Activities are also proposed in single-strata conditions but where stocking density is currently 

considered to be too high. Thinning activities would target the smaller diameter and less 

vigorous trees for removal, while maintaining the generally single-strata characteristics. This 

would encourage the development of large structure at an accelerated rate. In addition, reducing 

stocking density would increase tree vigor and reduce insect and disease hazard. 

The overall amount of LOS would not change immediately due to treatment, although 763 acres 

of multi-strata LOS would be converted to single-strata LOS. The overall amount of multi-strata 

LOS would not be reduced below historic levels; however, the amount of multi-strata LOS 

within the Douglas-fir PAG would drop below the historic range by 129 acres. By year 20, the 

amount of multi-strata LOS in the Douglas-fir PAG would increase to be within the historic 

range. After year 20, the amount of multi-strata LOS remains within or above the historic range 

for all PAGs. This alternative results in more single-strata LOS than Alternative 3, but less than 

Alternative 2. Tables 15 through 18 and Figures 1, 2, and 3 below display the predicted amounts 

of LOS that would occur under each alternative. 

Alternative 5 

Activities would generally move stands in a multi-strata condition to or towards a single-strata 

condition similar to Alternative 2; however, fewer acres would be treated and in several stands 

higher-density levels would be retained. Activities would generally move stands in a multi-strata 

condition to or towards a single-strata condition. Many stands would continue to be in an 

uneven-aged condition. Reducing stand density would reduce competitive stress on the 

remaining trees (Powell 1999). This would result in more large trees being maintained over 

time, as well as to encourage the development of additional large trees (Cochran et al. 1994). 

The abundance of early-seral species would be maintained and enhanced in the long-term; 

however, late-seral species would continue to be present in stands where they exist prior to 

treatment. Grand fir and Douglas-fir would be retained both in the overstory (all trees >21” dbh) 

as well as in the understory but at lesser amounts.
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 53 

Activities are also proposed in single-strata conditions but where stocking density is currently 

considered to be too high. Thinning activities would target the smaller diameter and less 

vigorous trees for removal, while maintaining the generally single-strata characteristics. This 

would encourage the development of large structure at an accelerated rate. In addition, reducing 

stocking density would increase tree vigor and reduce insect and disease hazard. 

The overall amount of LOS would not change immediately due to the proposed activities. The 

overall amount of multi-strata LOS would not be reduced below historic levels; however, the 

amount of multi-strata LOS within the Douglas-fir PAG would drop below the historic range by 

108 acres. By year 20, the amount of multi-strata LOS in the Douglas-fir PAG would increase to 

be within the historic range. After year 20, the amount of multi-strata LOS remains within or 

above the historic range for all PAGs. This alternative results in more single-strata LOS than 

Alternative 3, but less than Alternatives 2 and 4. Treatments in this alternative are similar to 

those in Alternatives 2 and 4, except for the modified prescriptions proposed for certain units 

with wildlife habitat emphasis. Those modifications include leaving portions of units untreated 

and/or retaining higher residual densities than Alternative 2 or 4. Modeling these modifications 

is outside the capabilities of the Viable Ecosystem model. Given the nature of these 

modifications, and the acres involved, it is reasonable to predict that the output of the model will 

overstate changes in vegetative stages by approximately 15 percent. Given that caveat, this 

alternative would move an estimated 685 acres of multi-strata LOS to single-strata LOS. Tables 

15 through 18 and Figures 1, 2, and 3 below display the predicted amounts of LOS that would 

occur under each alternative.

The projections for Alternatives 2, 3, 4, and 5 include only the proposed activities associated 

with each alternative. They do not include any future management such as continued 

underburning, thinning, or other stand-tending activities that may occur in the future. Thus, the 

predicted amounts of multi-strata LOS tend to increase with time as succession and stand growth 

continue without further management activities other than continued fire suppression. 

Cumulative Effects 

There are no active or planned timber sales within the Spears project area that would alter the

have been included in the description of the existing condition. There are no other vegetation 

projects (i.e. precommercial thinning or fuels reduction activities) currently ongoing or planned 

within the area. Approximately 1,500 acres of precommercial thinning from the 2002 Bandit II 

project have been completed within the area. This work was done in 2003 and 2004; fuels

reduction in these units (underburning and pile burning) has not been completed and is included 

in the action alternatives. 

Increased mortality from bark beetles was occurring in the project area following the Hash Rock 

Fire of 2000. It appears that the amount of mortality has decreased to endemic levels in the past 

2 years. No further increase in insect mortality is anticipated related to the Hash Rock Fire. 

Most of the private ownership within the project area is xeric ponderosa pine or juniper. Some 

nonforest land is also associated with homes and meadows. The privately owned forestland 

contains little, if any, LOS. It is foreseeable that land management practices on these lands 

would neither favor the development of additional LOS nor remove existing LOS. 

Early-seral Species Composition 

Affected Environment 

There are two primary processes that affect the movement of one seral structural stage to 

another. Species composition changes due to succession tend to favor shade-tolerant species and 

move stages from early seral to late seral. Growth moves stages from smaller structure to larger 

structural stages. Although some insects and disease disturbances are species specific and can 

move early seral to mid or late seral, natural disturbance processes (including fire, insects and 

diseases, and flooding) tend to move stages backward from mid or late seral to early seral. The 

magnitude of movement depends on the intensity of the disturbance. Some disturbances, such as 

low-intensity fire, may not affect the dominant stand character, but serve to maintain the existing 

stage. 

The projected future abundance of each stage is based on stand development assumptions for the 

various seral structural stages. The 20, 30, and 50-year time intervals were chosen to 

demonstrate development over time. These projections indicate that all alternatives move toward 

the HRV for the first 20 years. Between 20 and 50 years, the treatments proposed in the action 

alternatives provide a landscape which is closer to the HRV than the no action alternative. 

Environmental Consequences 

Alternative 1 

Vegetation would continue to develop within the project area in a manner determined by existing 

stocking and species composition. Many of the future stages, which develop through natural 

growth and succession, would tend towards mid or late-seral species composition and multistrata characteristics. Many of these conditions are already within or above HRV. The rate at 

which many stands develop large tree character would be hampered by overstocked conditions. 

On drier sites, such as ponderosa pine PAGs, stand stagnation would become more common. 

Existing trees would continue to be weakened by competition in overly dense stands. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 58 

Dense structural stages, already above the historic abundance, would continue to increase, 

reaching the highest levels of all alternatives. Acres dominated by grand and Douglas-fir (lateseral species) would steadily increase, while acres dominated by ponderosa pine and western 

larch (early-seral species) would steadily decrease. Tables 19 and 20 and Figures 4 and 5 display 

the effects of the five alternatives on species composition and dense conditions.

Effects Common to all Action Alternatives 

Proposed treatments (commercial harvest and precommercial thinning) are designed to reduce 

tree density and improve growth and vigor of the residual trees and reduce susceptibility to 

insects and disease. These treatments would more quickly restore historic seral/structural stage 

conditions and improve growing conditions for larger trees than either no action or prescribed 

fire alone. Commercial harvest and precommercial thinning would decrease the probability of 

crown fires, reducing the potential area burned by unwanted fires, and would decrease potential 

fire severity (Peterson et al. 2005). 

Alternative 2 

The abundance of early-seral species would be maintained and enhanced in the long-term; 

however, late-seral species would continue to be present in stands where they exist prior to 

treatment. Grand fir and Douglas-fir would be retained both in the overstory (all trees >21” dbh) 

as well as in the understory but at lesser amounts.

Acres dominated by grand and Douglas-fir would be reduced the most of any alternative, yet 

remain with the historic range. Acres dominated by ponderosa pine and western larch would be 

increased by about 650 acres due to treatment, and increase by an additional 700 acres over the 

next 20 years. 

Alternative 3 

Early-seral or disease-resistant species would be selected for retention where possible. Because 

only small trees would be removed, the amount of competition among the remaining trees would 

vary depending on the larger density and it may not be possible to reach recommended stocking 

levels in some units. The ability to change species dominance from late seral to early seral will 

be limited in stands where there is an abundance of late-seral trees 9 inches dbh and larger. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 60 

Acres dominated by grand and Douglas-fir would be reduced by about 300 acres, the least of any 

action alternative. Acres dominated by ponderosa pine and western larch would be increased by 

about 865 acres due to treatment, then increase by 600 acres over the next 20 years, surpassing 

the amount in Alternative 1 at that time. 

Alternative 4 

The abundance of early-seral species would be maintained and enhanced in the long-term; 

however, late-seral species would continue to be present in stands where they exist prior to 

treatment. Grand fir and Douglas-fir would be retained both in the overstory (all trees >21” dbh) 

as well as in the understory but at lesser amounts.

Acres dominated by grand and Douglas-fir would be reduced by more than 800 acres, but stay 

within the historic range. Acres dominated by ponderosa pine and western larch would be 

increased by about 400 acres due to treatment, and increase by an additional 700 acres over the 

next 20 years. 

Alternative 5 

The abundance of early-seral species would be maintained and enhanced in the long-term; 

however, late-seral species would continue to be present in stands where they exist prior to 

treatment. Grand fir and Douglas-fir would be retained both in the overstory (all trees >21” dbh) 

as well as in the understory but at lesser amounts.

Acres dominated by grand and Douglas-fir would be reduced by about 250 acres, but stay within 

the historic range. Acres dominated by ponderosa pine and western larch would be increased by 

about 425 acres due to treatment, and increase by about 400 additional acres over the next 20 

years. 

Cumulative Effects 

There are no active or planned timber sales within the Spears project area that would alter the 

amount of area dominated by ponderosa pine and western larch. The effects of past harvest and 

other activities have been included in the description of the existing condition as described 

previously. There are no other vegetation projects currently ongoing or planned that would alter 

the amount of area dominated by early-seral species. 

Infestations by Insects and Disease 

Affected Environment 

Past management practices, including fire exclusion and selection harvest, have favored the 

development of stands, which are now considered to be out of balance when compared to their 

historic conditions. Historically (100+ years ago) stands in the project area would have 

commonly had more ponderosa pine and western larch and less grand fir and Douglas-fir. They 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 61 

would have been more open and single storied rather than the multi-storied stands of today. 

These stand conditions were maintained by frequent, low-intensity fires, which prevented them 

from becoming overcrowded. The natural disturbance agents found in the project area, have 

always been present; however, the degree to which they now affect the area can be considered to 

be a reflection of the ecosystem’s health and resiliency. 

Bark Beetles: Aerial insect and disease surveys for years 1996 through 2006 show numerous 

active mortality centers due to bark beetle feeding. Stand exams and field reconnaissance also 

identified bark beetle activity and susceptible stand conditions. Elevated levels of western pine 

beetle occurred in the area following the Hash Rock Fire. At this time, it appears that elevated 

mortality from that event has declined. 

Mountain pine beetle (Dendroctonus ponderosae) and western pine beetle (Dendroctonus 

brevicomis) occur in the project area. Ponderosa pine is a susceptible host in overstocked stands. 

Bark beetle mortality is symptomatic of over-stocked stand conditions that create competition 

stress and reduce tree vigor (Schmid et al.1994 and Graham and Knight 1965). Thinning 

(density reduction) has been shown to be effective in reducing bark beetle susceptibility in stands 

(Fettig et al. 2007). 

Douglas-fir beetle (Dentroctonus pseudotsugae) and the fir engraver (Scolytus ventralis) also 

occur in the project area. Both of these insects are regarded as secondary pests because they 

attack trees that are weakened and stressed. Factors such as drought, defoliation, overstocking, 

and disease can result in outbreaks of these insects that can cause increased mortality within a 

stand. 

Defoliating Insects: From approximately 1987 to 1992, this project area, along with the rest of 

the Ochoco Mountains, experienced an outbreak of western spruce budworm which caused large 

amounts of trees damage and/or mortality in nearly all stands in which grand fir and Douglas-fir 

are major components. Beginning in 1992, the Marks and Harpo timber sales included harvest in 

stands with high levels of mortality and damage from the western spruce budworm. Attributes, 

which contribute to high susceptibility to defoliating insects, are: (1) increased amount of later 

seral host species, (2) increased stand densities, and (3) the development of multi-storied stand 

structures (Carlson and Wulf 1989). The trend without vegetative treatments would be for these 

characteristics to increase until insect population dynamics and climatic conditions combine to 

generate another outbreak of epidemic proportions. 

Dwarf mistletoe: Dwarf mistletoes are present in the project area. Ponderosa pine dwarf 

mistletoe (Arceuthobium campylopodum) decreases tree vigor, reduces growth, and increases 

susceptibility to other pathogens (Hawksworth and Shaw 1987). Infections in trees of the upper 

canopies spread readily to trees in the lower canopies. Douglas-fir dwarf mistletoe 

(Arceuthobium douglasii) causes growth loss, reduced wood quality, topkill, and mortality. 

Dwarf mistletoes are largely specific to one or two host tree species. In other words, Douglas-fir 

dwarf mistletoe would not be expected to infect ponderosa pine (Knutson and Tinnin 1980). 

Dwarf mistletoes accelerate the movement to mid and late-seral species compositions by 

reducing the vigor of infected early-seral species and increasing the competitive edge of later-
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 62 

seral species. Dwarf mistletoes cause branch structure to broom creating nest and hiding sites for 

many animals. Some animals forage on dwarf mistletoe plants. 

Dwarf mistletoes are probably more common at present than historically due to the reduction of 

normal fire events. Dwarf mistletoe spreads from infected trees to adjacent trees that are close 

enough to catch mistletoe seeds as they are released from the plant. Historically more stands in 

the project area were open with fewer understory trees. Frequent, low-intensity fire would have 

scorched lower branches and killed infected branches which would have reduced or prevented 

the spread of mistletoe. As stands have become more dense and multi-strata, dwarf mistletoes 

have been able to spread faster. As height growth slows due to infected branches, dwarf 

mistletoe moves more quickly into the higher tree crown. Brooming branches contribute to 

ladder fuels that allow wildfires to reach tree crowns increasing the risk of crown fire initiation. 

Dwarf mistletoe management can be directed at either prevention or reduction. The most 

effective treatment for dwarf mistletoe control is to remove infected overstory trees; this project 

does not include the removal of large trees over 21 inches dbh. Harvest or precommercial 

thinning in the lower canopies can and does reduce stocking and can effectively reduce some 

growth loss, improve vigor, and reduce re-infection (Roth and Barrett 1985). Favoring an 

immune tree species when performing thinning is also an effective method of dwarf mistletoe 

management (Knutson and Tinnin 1980). 

Root disease: Armillaria root disease and laminated root rot are present in the project area. 

They are most evident within stands of high density and those with a major component of laterseral species. Vigorously growing trees can be infected but can often confine the fungi and limit 

the extent of the infection (Hadfield et al. 1986). Most of the root disease activity in the project 

area can be found in the grand fir PAG, especially in areas where stand conditions combine to 

reduce stand vigor. These diseases can kill trees directly, and often work in conjunction with 

insects and disease to create pockets or patches of mortality (Hagle and Shaw 1991). 

Historically, these disease centers were usually small and contributed to stand diversity. With 

the changes over time in species composition, the incidence of and susceptibility to root disease 

infection is increasing. The tendency, without disturbance, is for infection centers to be 

repopulated with host tree species and for infections to perpetuate and intensify. 

Table 21 displays the seral/structural stages by PAG that are considered to be at high risk of 

damage by insects and diseases.

Chapter 3 - Affected Environment and Environmental Consequences

Environmental Consequences 

Alternative 1 

No actions would be taken to reduce susceptibility to insects and diseases. Vegetative 

development would continue dependent on the conditions and successional trends which 

currently exist. More of the project area would develop conditions such as high density and an 

abundance of later-seral species. High risk stages would become more abundant in the future. In 

20 years the amount of high risk area is projected to increase by an additional 4,600 acres. 

Table 22 and Figure 6 below display the amount of high risk area associated with each 

alternative. 

Effects Common to Alternatives 2, 3, 4, and 5 

The proposed activities would reduce susceptibility to insects and disease by decreasing tree 

density, favoring early-seral species, and moving towards single-strata conditions which were 

more abundant historically. Decreasing tree density would result in increased growing space and 

less competition for the remaining trees. This would increase their vigor and lessen the risk of 

tree mortality caused by bark beetles and root diseases. The susceptibility to western spruce 

budworm would be reduced by (1) favoring early-seral species (ponderosa pine and western 

larch) which are not preferred primary hosts, (2) reducing multilayered canopy conditions which 

support larval survival during dispersal, and (3) improving tree vigor and the ability to withstand 

attack. Susceptibility to dwarf mistletoe would be reduced by (1) favoring non-host tree species, 

(2) reducing dense multilayered canopy conditions favorable to seed dispersal, and (3) improving 

tree vigor which would allow for increased tree height growth. 

Alternative 2 

This alternative reduces the high-risk stages by more than 3,000 acres. This alternative brings 

the amount of area into the range at which it historically occurred. The proposed activities 

would reduce stand densities, increase the relative abundance of early-seral species, and increase 

resistance to disturbance agents. This alternative reduces the acres of high risk condition the 

most of all alternatives. This trend continues through the 50-year projection period. 

Alternative 3 

This alternative reduces the high-risk stages by almost 800 acres, and brings the amount of area 

just into the range at which it historically occurred. This alternative is predicted to have the least 

amount of risk reduction of all the action alternatives. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 64 

Alternative 4 

This alternative reduces the high-risk stages by almost 2,700 acres, and brings the amount of area 

into the range at which it historically occurred. The proposed activities would reduce stand 

densities, increase the relative abundance of early-seral species, and increase resistance to 

disturbance agents. 

Alternative 5 

As discussed previously, the predictions made by the Viable Ecosystem model are not able to 

fully account for the modified prescriptions incorporated into this alternative. It can be 

anticipated that the untreated patches within units, and the areas retaining more than the 

recommended stocking level would continue to be in a high risk stage. The model prediction of 

amount of high risk area reduced is potentially overstated by about 15 percent. The actions 

proposed in this alternative, however, are estimated to reduce the high-risk stages by almost 

2,400 acres, and bring the amount of area into the range at which it historically occurred.

stand-tending activities, which may occur. Thus, the acres of high risk increase with time as 

succession and stand growth continue uninterrupted.

Cumulative Effects 

There are no ongoing or planned activities, other than those described in the action alternatives, 

that would reduce the amount of area in the high risk stages. Therefore, there are no cumulative 

effects that relate to insect and disease susceptibility. 

Fuels 

Affected Environment 

The most common natural disturbance that has had an effect on vegetation in the project area is 

lightning-caused fire. Fire exclusion over the last 90-100 years has reduced the acres burned 

from naturally occurring, low-intensity fires. Frequent, low-intensity fires removed both surface 

and ladder fuels resulting in more open forest stands than what occur today. When fire is kept 

out of forest stands, both surface and ladder fuels increase and stands become denser, which 

increases the likelihood of high-intensity wildfire. As a result of fire exclusion, the amount of 

fuel loadings and the density of forest stands have increased. 

Fire regimes describe the role of fire as a disturbance process for a given landscape. A fire 

regime is defined as the fire frequency or interval as “the average number of years between fires” 

and severity as the “effect of the fire on the dominant over story vegetation” (Hardy et al. 2001 

and Schmidt et al. 2002). The majority of the Spears project area is classified as Fire Regimes I 

and III which correlates with the ponderosa pine PAG at the lower elevations and mixed conifer 

at upper elevations. 

Fire regimes are divided into five levels of historical natural fire occurrences; only three of the 

five regimes occur within the Spears project area. Fire regime is a reflection of the biophysical 

environment that occurs across a landscape, hence none of the alternatives would have any effect 

on fire regime. 

Fire Regime Condition Class (FRCC) is used to describe general landscape fire regime and 

vegetation/fuel characteristics. Estimates of these characteristics are calculated for comparison 

with estimates of natural fire regime reference values and reference condition vegetation/fuel 

characteristics to index FRCC (a classification of the amount current conditions have departed 

from those of historical reference conditions). 

Condition classes are generally equivalent to low, moderate, and high departure from the natural 

or historical range of variability (HRV). 

Table 23 displays the effects of the alternatives on condition class within each fire regime for the 

Spears project area.

Fire Regime I includes the ponderosa pine and Douglas-fir PAGs. Fire Regime I comprises 

about 35 percent of the project area. Currently, areas within this fire regime exhibit a moderate 

amount of departure (43%) from reference conditions, primarily a deficiency of late-seral, open 

vegetation/fuels conditions. Alternatives 2 through 5 reduce the amount of departure. 

Alternatives 2, 4, and 5 move this fire regime into condition class 1. 

Fire Regime II is a minor component in the project area. The juniper woodland PAG is Fire 

Regime II. Within Fire Regime II, there is a lack of open, early-seral condition compared to 

reference conditions. This results in a moderate amount of departure and is classified as 

condition class 2. There is little if any treatment proposed for Fire Regime II under any of the 

alternatives and the condition class remains the same for all alternatives. 

Fire Regime III comprises 61 percent of the project area. Current vegetation and fuels conditions 

are similar to reference conditions, with departure at 16 percent and in condition class 1. 

Alternatives 2 through 5 reduce the amount of departure as shown in the table above. This 

occurs primarily by increasing the amount of late-seral, open vegetation/fuels conditions. 

Environmental Consequences 

Alternative 1 

This is the no action alternative and no fuel reduction activities, including prescribed fire, would 

occur. No fuel reduction activities would occur within the WUI. In the absence of frequent, 

low-intensity fires, forest stands in the project area have developed multi-canopy conditions, 

stocking levels have increased, ladder fuels have increased, surface fuels have increased, and the 

abundance of late-seral, fire-intolerant species (such as grand fir) has increased. These changes 

from historic conditions have left forested stands susceptible to high-intensity wildfire, with an 

increased potential for the unwanted loss of trees, water quality, soil productivity, wildlife 

habitat, and other forest resources. These trends would continue. The amount of the project area 

that is in condition class 1 would decrease over time as both surface and ladder fuels increase. 

The amount of the project area in condition classes 2 and 3 would increase as fuels accumulate 

and departures from reference conditions increase. Over time, the amount of area with the 

potential for high-intensity wildfire would increase while the amount of area that would support 

low-intensity fire would decrease. 

There are no ongoing or reasonably foreseeable activities in the project area that would reduce 

the amount of fuel accumulations and reduce the potential for high-intensity wildfire. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 67 

Alternative 2, 4, and 5 

Direct and Indirect Effects 

These alternatives include several types of fuel reduction activities including activity-fuels 

underburning, natural fuels underburning, piling, and jackpot burning. Precommercial thinning 

and commercial timber harvest are also considered because they would reduce ladder fuels. The 

amount of each fuel reduction activity varies by alternative as displayed in Table 24. Fuel 

reduction activities would occur both within and outside the WUI. In Alternative 2, an estimated 

8,493 acres would be treated in the WUI. In Alternative 4, the amount of treatment in the WUI 

is an estimated 8,474 acres. In Alternative 5, an estimated 8,112 acres would be treated within 

the WUI. 

Fuel reduction activities may be used alone or in combination. For example, most areas where 

precommercial thinning is prescribed also include activity-fuels underburning to reduce the 

amount of surface fuel created by the thinning activity. In all areas where commercial harvest is 

prescribed, there would be a follow-up activity such as grapple piling, hand piling, and/or 

underburning to reduce the activity fuels.

Jackpot burning 219 265 910 

Prescribed fire operations that are conducted after harvest and thinning operations would reduce 

activity fuels (i.e. slash). These fuels are surface fuels and consist of limbs, branches, tree tops,

and small trees. Based on prescribed fires in the Trout, Mill, Yobear, and Sheep Rock areas, 40 

to 70 percent of the surface area of prescribed fire units is burned, thereby removing surface 

fuels. These fire operations would reduce the density of seedlings and saplings (generally less 

than 3 inches dbh) in these stands and may result in small changes in species composition. 

Because ponderosa pine and western larch are fire-tolerant species, small trees of these species 

are more likely to survive while fire would kill many of the small fir trees. In addition to 

removing activity fuels, prescribed fire operations would also reduce some of the natural fuel 

accumulations. Prescribed fire in these stands would also prune the lower branches of larger 

trees, increasing the distance from the forest floor to the crowns of those trees, making them less 

susceptible to high-intensity wildfire. 

Activity fuels created by commercial harvest and precommercial thinning cause a short-term 

increase (up to 6 years) in the potential for high-intensity wildfire because they increase the 

amount of surface fuels. For the first year after thinning, the fuel moisture in green slash makes 

it unavailable to burn, unless a wildfire occurs under extreme conditions (Rothermel et al. 1986). 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 68 

After approximately 1 year, the slash has dried out, needles have turned red, and slash is 

available to burn. Should a wildfire occur during this time, the additional heat generated by the 

increased fuel load has the potential to cause undesired effects to the surrounding stand, soils, 

and other resources. This hazard is mitigated by either lopping (cutting) the slash to reduce the 

height of the fuel bed so that it is under 12 inches, or by piling the slash. Lopping and piling 

both reduce fire intensity by rearranging fuels. In units that have been lopped, after 2 or 3 years 

the slash gets further compacted by winter snows and can be burned with a low-intensity 

underburn. This delay also allows for the redistribution of nutrients from the slash back into the 

soil (Graham et al. 1999). 

In three units (110, 210, and 810), underburning would occur prior to commercial harvest and 

precommercial thinning to reduce the existing amount of fuels in these stands. These prescribed 

fire operations would kill many small trees (generally less than 3 inches dbh). Some medium 

and large trees may also be killed by fire; the trees most likely to be killed by fire operations are 

fire-intolerant species such as fir. Based on past experience, between 1 and 10 percent of the 

medium and large trees may be killed. Fire operations in these three stands would reduce the 

density of the stand by removing trees and would change the species composition by removing 

fire-intolerant trees. However, in these three units underburning alone would not remove enough 

trees. 

Maintenance or natural fuels underburning would occur in many stands. Maintenance 

underburning would remove mostly surface fuels. Some small trees less than 3 inches dbh 

would be killed, but these activities are not expected to change the density of the forested stand 

or the species composition because these stands tend to be more open with relatively low fuel 

levels. Prescribed fire in these stands would also remove some ladder fuels by pruning the lower 

branches of larger trees, increasing the distance from the forest floor to the crowns of those trees, 

making them less susceptible to high-intensity wildfire. 

The number of units that would include jackpot burning varies by alternative. Jackpot burning 

would be completed after commercial harvest and/or precommercial thinning operations to 

remove concentrations of activity fuels prior to underburning. In combination, the prescribed 

fire operations would reduce both surface and ladder fuels. 

In some areas, activity fuels would be piled, either by hand or grapple machines. Where fuels 

are piled, an estimated 60-70 percent of the surface fuels would be piled and burned. Where 

piles are located, there would be small amounts of soil scorching. Hand piles tend to be small (5-

6 feet high by 3-4 feet wide) and burning these piles would not alter the species composition or 

density of surrounding stands. Grapple piles are generally 5-10 feet high and 10-15 feet wide. 

Radiant heat from grapple piles may occasionally kill nearby trees, but not enough to measurably 

change species composition or stand density. Piling allows the fuels to be treated sooner, 

generally within 1-2 years. 

All of the activities described above that reduce ladder and surface fuels also reduce the potential 

for crown fire, crown scorch (which kills trees by scorching their needles with convective heat), 

radiant heat damage to cambium (the inner bark of trees, where diameter growth occurs), and 

radiant heat damage to soils and tree roots (Saveland and Nuenschwander 1989).

Linking Spears units with previous activity areas would increase the likelihood that suppression 

actions would be successful if an unplanned ignition does occur. Activities along ingress/egress 

routes such as U.S. Highway 26 and Roads 27, 2630, 2620, 2610, 2610-150, and 3350 would 

reduce fuels within these road corridors and contribute to safe evacuation routes for both 

homeowners and visitors in the project area. Reducing fuels would increase the likelihood that 

wildfires would be suppressed while they are small and would reduce the risk of wildfires 

spreading between NFS lands and private lands. Finally, unplanned ignitions in or near OGMA, 

the Mill Creek Wilderness, and the Ochoco Divide RNA may be more successfully suppressed. 

All of these fuel reduction activities would reduce the amount of departure from reference 

conditions and would move fire regime I into condition class 1. Table 23 displays the changes in 

percent departure from reference conditions. 

Alternative 3 

Direct and Indirect Effects 

This alternative includes activity fuels underburning, natural fuels underburning, hand piling, and 

jackpot burning. Precommercial thinning is considered a fuel reduction activity because it 

reduces ladder fuels. The amount of each fuel reduction activity is displayed in Table 25. Fuel 

reduction activities would occur both within and outside the WUI. This alternative includes an 

estimated 7,722 acres of fuel reduction activities within the WUI. These activities may be used 

alone or in combination. For example, most areas where precommercial thinning is prescribed 

also include activity-fuels underburning to reduce the amount of surface fuel created by the 

thinning activity. 

Prescribed fire operations would be conducted after thinning operations to reduce activity fuels. 

These fuels are surface fuels and consist of limbs, branches, tree tops, and small trees. Based on 

prescribed fires in the Trout, Mill, Yobear, and Sheep Rock areas, 40 to 70 percent of the surface 

area of prescribed fire units is burned, thereby removing surface fuels. These fire operations 

would reduce the density of seedlings and saplings (generally less than 3 inches dbh) in these 

stands and may result in small changes in species composition. Because ponderosa pine and 

western larch are fire-tolerant species, small trees of these species are more likely to survive 

while fire would kill most of the small fir trees. In addition to removing activity fuels, 

prescribed fire operations would also reduce some of the natural fuel accumulations. Prescribed 

fire in these stands would also prune the lower branches of larger trees, increasing the distance 

from the forest floor to the crowns of those trees, making them less susceptible to high-intensity 

wildfire.

Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 70 

Precommercial thinning would cause a short-term increase (up to 5 years) in the potential for 

high-intensity fire because they increase the amount of surface fuels. For the first year after 

thinning, the fuel moisture in green slash makes it unavailable to burn, unless a wildfire occurs 

under extreme conditions (Rothermel et al. 1986). After approximately 1 year, the slash has 

dried out, needles have turned red, and the slash is available to burn. Should a wildfire occur 

during this time, the additional heat generated by the increased fuel load has the potential to 

cause undesired effects to the surrounding stand, soils, and other resources. This hazard is 

mitigated by either lopping (cutting) the slash to reduce the height of the fuel bed so that it is 

under 12 inches, or by piling the slash. Lopping and piling both reduce fire intensity by 

rearranging fuels. In units that have been lopped, after 2 or 3 years the slash gets further 

compacted by winter snows and can be burned with a low-intensity underburn. This delay also 

allows for the redistribution of nutrients from the slash back into the soil (Graham et al. 1999). 

Maintenance or natural fuels underburning would occur in many stands. Maintenance 

underburning would remove mostly surface fuels. Some small trees would be killed, but these 

activities are not expect to change the density of the forested stand or the species composition 

because these stands tend to be more open with relatively low fuel levels. Prescribed fire in 

these stands would also remove some ladder fuels by pruning the lower branches of larger trees, 

increasing the distance from the forest floor to the crowns of those trees, making them less 

susceptible to high-intensity wildfire. 

In some areas, activity fuels would be hand piled. Where fuels are piled, an estimated 60-70 

percent of the surface fuels would be piled and burned. Where piles are located, there would be 

a small amount of soil scorching. Hand piles tend to be small (5-6 feet high by 3-4 feet wide) 

and burning these piles would not alter the species composition or density of surrounding stands. 

Piling allows the fuels to be treated sooner, generally within 1-2 years. 

Linking Spears units with previous activity areas would increase the likelihood that suppression 

actions would be successful if an unplanned ignition does occur. Activities along ingress/egress 

routes such as U.S. Highway 26 and Roads 27, 2630, 2620, 2610, 2610-150, and 3350 would 

reduce fuels within these road corridors and contribute to safe evacuation routes for both 

homeowners and visitors in the project area. Reducing fuels would also increase the likelihood 

that wildfires would be suppressed while they are small and would reduce the risk of wildfires 

transitioning between NFS lands and private lands. Finally, unplanned ignitions in or near 

OGMA, the Mill Creek Wilderness, and the Ochoco Divide RNA boundaries may be more 

successfully suppressed. 

All of the activities described above that reduce ladder and surface fuels also reduce the potential 

for crown fire, crown scorch, radiant heat damage to cambium, and radiant heat damage to soils 

and tree roots (Saveland and Nuenschwander 1989). Even though these activities would reduce 

the amount of departure from references conditions, they do not change condition class. Table 

23 displays the changes in percent departure from reference conditions. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 71 

Cumulative Effects 

Past activities such as the Hash Rock Fire and the Marks Creek Burn reduced fuel loading in the 

project area. Prescribed fire activities that were completed before the Bandit II decision was 

withdrawn reduced the fuel loading on 1,726 acres. In some areas, the amount of surface fuels 

increased as a result of precommercial thinning activities authorized under the Bandit II decision. 

In many cases, such as in Unit 535, no activity fuel treatment was completed because the 

decision was withdrawn. The action alternatives in the Spears project include follow-up fuels 

treatments in these areas. The effects of these and other past activities such as timber harvest 

were taken into account when describing the affected environment and the number of acres in 

each condition class. 

There are no other activities in the project area that would reduce fuels and result in changes in 

condition class. 

Potential Fire Behavior and Probability 

Affected Environment 

Potential fire behavior and probability for the Spears project area was analyzed utilizing 

FlamMap, Version 3 (Finney et al. n.d.) and ArcFuels (Ager 2005). Modeling was used to 

predict various fire behavior characteristics and probabilities of occurrence for Alternative 1 (no 

action) to assess the affected environment as well as the four action alternatives to assess 

changes as a result of proposed treatments. All assessments used the same weather and fuel 

condition scenario so that the effects of different alternatives could be consistently compared. 

Scenarios were modeled under hot dry conditions with a 10 mile per hour northwesterly wind 

across the project area. Fire behavior attributes assessed include flame length, rate of spread, and 

potential crown fire activity. 

Flame length is the distance between the flame tip and the midpoint of the flame depth at the 

base of the flame (generally the ground surface); flame length is an indicator of fire intensity. 

Flame lengths less than 4 feet are generally of low enough intensity that suppression crews can 

directly attack the fire, while flame lengths more than 4 feet require that control lines be built 

using heavy equipment. Flame lengths more than 8 feet generally require indirect suppression 

tactics and in many cases indicate intensities high enough to result in stand replacement events.

5 55% 13% 9% 22% 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 72 

Rate of spread is measured in chains (66 feet) per hour and is used to determine the type and 

number of resources that would be needed to suppress a fire. Faster rates of spread generally 

result in larger fires which are more difficult to control. 

Table 27. Rate of spread by alternative.

3 46% 16% 16% 22% 

4 49% 15% 15% 21% 

5 47% 16% 16% 22% 

Crown Fire Activity - Two types of potential fires were predicted; surface fire (no crown fire) 

and crown fire (both passive and active). Crown fire activity can be used as an indicator of 

potential stand effects with surface fire generally having the least effect on stand structure, 

density, and composition while crown fire generally indicates a fire behavior resulting in at least 

partial stand replacement. 

Table 28. Crown fire activity (percent of project area) by alternative.

1 20% 80% 

2 53% 47% 

3 49% 51% 

4 53% 47% 

5 51% 49% 

Burn Probability - To asses the overall susceptibility of the landscape to burning, 1,000 random 

ignitions were used to assess changes for each alternative. High burn probabilities are directly 

correlated to fire sizes that occur on a landscape under similar conditions. Large fires produce 

higher probabilities than small fires since each fire burns a larger fraction of the landscape. 

Since fire size is a function of the gross spread rate and duration of the fire, activities or 

conditions that reduce the spread rate also lower burn probabilities.

Environmental Consequences 

Alternative 1 

There would be no activities that would result in modifying fire behavior or burn probabilities 

across the project area other than continued fire suppression efforts for unplanned wildfires. 

Fuel conditions within the area currently support potentially high fire intensities, high rates of 

spread, and a large amount of potential crown fire behavior (80%). See Tables 26 to 29. Fortyone percent of the project area has a low-burn probability, while 59 percent has a moderate or 

high probability. Continued stand growth, successional changes, and continued fire exclusion 

would result in these indicators increasing over time. 

Alternatives 2, 3, 4, and 5 

All action alternatives include activities that would modify fire behavior by reducing ground 

fuels, reducing ladder fuels (small understory trees), and removing activity-generated fuels 

following commercial harvest and precommercial thinning. All action alternatives would result 

in reducing areas that support higher flame lengths and faster rates of spread. All action 

alternatives reduce the amount of area which could potentially support crown fire by 

approximately 30 percent. Under all action alternatives, there is approximately a 50 percent 

increase in the amount of low-burn probability over that predicted for Alternative 1. 

Although the FlamMap predictions for fire behavior and burn probability show slight differences 

between Alternatives 2, 3, 4, and 5, these differences are not meaningful because they fall within 

the uncertainty and randomness associated with the model. All action alternatives produce 

essentially the same result because there are only small differences between the total amount of 

treatment and the arrangement of treatments within the project area. All activities in all action 

alternatives are designed to reduce surface and ladder fuels, which are the primary factors 

associated with fire behavior. 

Cumulative Effects 

There are no other actions proposed on NFS lands within the project area which would modify 

potential fire behavior. It is foreseeable that activities on private lands would be undertaken to 

reduce potential fire behavior and fire effects. Oregon Department of Forestry has recently 

acquired a grant from the National Fire Plan to perform fuel reduction activities adjacent to 

private homes inside the Spears project area. These activities would lessen potential fire effects 

on private lands and would probably be geared towards providing defensible space around 

structures. There are approximately 2,300 acres of private land within the area. It is unknown 

how much of this area might be treated to lessen potential fire behavior but given that the total 

amount of private land is a relatively small amount of the project area (less than 6%), it is 

unlikely that these activities would have a measurable effect on the potential fire behavior and 

probability across the landscape. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 74 

Hardwood Plant Communities 

Affected Environment 

Quaking aspen and cottonwood provide unique and special habitats. The project area contains 

numerous small aspen stands usually associated with riparian areas. Aspen develop as clones 

where individual trees are short-lived and are replaced by sprouts from the root system. Aspen is 

sensitive to conifer encroachment and accompanying shading, browsing by livestock and big 

game, and reduced water tables. 

Both cottonwood and aspen grow in self-perpetuating clones in areas of locally high moisture such 

as meadows, seeps, and adjacent to streams. Conifer trees are encroaching into aspen and 

cottonwood stands in the project area. These conifers compete with the hardwood trees for light, 

moisture, and growing space. Since the hardwood trees are not shade tolerant, they can be 

shaded out by the encroaching conifers, which results in loss of vigor for the hardwoods in the 

short term, and can lead to loss of the clone(s) in the long term. 

Environmental Consequences 

Alternative 1 

No thinning activities would occur. Conifer trees would continue to encroach into aspen and 

cottonwood stands in the project area. These conifers compete with the hardwood trees for light, 

moisture, and growing space. Since the hardwood trees are not shade tolerant, they would 

continue to be shaded out by the encroaching conifers. Aspen and cottonwood trees would 

continue to lose vigor and, in the long-term, clones may shrink or die out. 

Alternatives 2, 3, 4, and 5 

Thinning would occur in 196 acres of hardwood stands. These thinning activities would result in 

cutting or girdling conifer trees. Removing conifer trees within and adjacent to aspen and 

cottonwood stands would reduce competition for light, moisture, and other nutrients and 

maintain hardwood plant communities. Cottonwood and aspen would become more vigorous, 

increasing sprouting and the longevity of mature trees. 

Thinning would occur in 196 acres of hardwood stands under each of the action alternatives. 

These thinning activities would involve cutting or girdling conifer trees up to 12 inches dbh. 

Removing conifer trees within and adjacent to aspen and cottonwood stands would reduce 

competition for light, moisture, and other nutrients. Slash arrangement, individual cages, and 

fencing would protect developing sprouts from being browsed. An exclosure fence is proposed 

to be constructed within one of the two cottonwood stands on Peterson Creek, unit 145. In unit 

145 half of the stand would be fenced with a big game exclosure, while the other half would 

have a livestock exclosure with individual cages within it. Slash would be lopped and scattered. 

In the other cottonwood stand on Peterson Creek, unit 916, no fence would be constructed. Most 

slash would be lopped and scattered; however, some individual trees would be felled to provide 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 75 

protection to streambanks and to protect individual sprouts. In aspen stands, most slash would 

be lopped and scattered while some individual trees would be arranged to provide protection to 

sprouts. Aspen exclosure fences would be constructed, as follows: Sears Creek unit 915, two big 

game exclosures; Marks Creek units 507 and 908, two big game exclosures; Coyle Butte units 

525 and 910, two big game exclosures; Rush Creek unit 533, one livestock exclosure with 

individual cages; Crystal Creek units 407, 408, 552, 577 and 909, three big game exclosures and 

two livestock exclosures with individual cages within them; McGinnis Creek unit 737, one big 

game exclosure. Small cages would be constructed to protect aspen sprouts in other stands, as 

follows: Crystal Creek units 409, 410, and 411; Coyle Butte units 403, 404, and 405; Cornez 

Creek unit 401; Deadman Creek unit 914; Little Hay Creek unit 402; Grant Meadows units 406, 

911, 912, and 913. This would allow small sprouts to develop into sapling and pole sized stems, 

that would provide future replacements for larger overstory trees. Sprout protection would be 

limited to strategic arrangement of slash in units 502, 745, 904, and 905 in order to meet visual 

objectives at the sno-park and along Road 27. Cottonwood and aspen would become more 

vigorous, increasing sprouting and the longevity of mature trees. Aspen and cottonwood clones 

would be expected to be maintained or increased in extent and vigor as a result. 

Cumulative Effects 

Past, present, and reasonably foreseeable actions with effects that could combine with effects of 

the proposed action, and which would result in effects to hardwood communities include riparian 

planting, construction of exclosure fences and individual cages, the repair of headcuts, road 

construction, ongoing road maintenance, and livestock grazing. 

In the last several years, riparian planting has occurred along Marks, Reilly, McGinnis, Rush, 

Deadman, Little Hay, E. Fork Hamilton, and W. Fork Hamilton Creeks. Riparian planting and 

the protection of riparian vegetation with exclosures and cages have contributed to increased 

extent and development of riparian hardwood habitat. Livestock grazing in riparian areas 

generally has reduced the stature and abundance of hardwood sprouts because livestock consume 

leaves and small branches and trample sprouts. However, the development of upland watering 

sites and salt stations, and the use of riders associated with livestock management would have 

helped distribute cattle out of the riparian areas, thus partially compensating for past browsing 

and trampling damage. Livestock are expected to continue grazing in the four allotments that 

overlap the project area. Livestock browsing and trampling are expected to continue; however, 

constructing big game and livestock exclosures and individual cages around sprouts would 

reduce the amount of damage to hardwoods. 

Repair of headcuts with step-pool structures improved channel stability and maintained water 

tables above the structures which maintains potential to support riparian vegetation. In 2002 and 

2003, headcuts were repaired on Little Hay and McGinnis Creek. Though road construction has 

in some areas intercepted natural drainage and concentrated flow along ditches, road 

maintenance would generally promote cross draining of water to ensure continued down slope 

hydrology which is vital to maintenance of riparian vegetation. Since 2000, nine culverts have 

been replaced, one culvert was removed, and road decommissioning occurred on Roads 2600-

021, 2600-022, 2600-253, 2600-301, 2610-012, and 3300-550. These activities have all 

increased stream drainage to ensure continued down slope hydrology. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 76 

The effects of restorative activities (planting, protection, headcut repair, road work, off-site 

salt/water) when combined with the effects of this project on hardwood stands complement each 

other in promoting riparian hardwood habitat. The effects of browsing, trampling, and 

hydrologic interception are at least partially compensated for by the beneficial effects of the 

proposed activities on riparian hardwoods. Considering past, present, and reasonably foreseeable 

activities, aspen and cottonwood clones would be expected to be maintained or increased in 

extent and vigor. 

Riparian Habitat Conservation Areas 

Affected Environment 

Riparian Habitat Conservation Areas (RHCAs) are portions of watersheds where riparian 

dependent resources receive primary emphasis, and management activities are subject to specific 

standards and guidelines contained in INFISH. 

For streams, the width of RHCAs are determined by whether it is fish-bearing and whether it is 

perennial or intermittent. There are an estimated 4,546 acres of RHCAs in the project area. In 

addition to streams, RHCAs also occur around ponds, lakes, reservoirs, wetlands, landslides, and 

landslide-prone areas. RHCAs for these areas have not been mapped and are not included in the 

estimated acres of RHCAs within the project area. As noted in the design criteria in Chapter 2, 

seeps, springs, and landslides would have RHCAs around them. There are no ponds, lakes, 

reservoirs, or wetlands greater than 1 acre in size on NFS lands within the project area. 

Class I and II streams are fish-bearing and RHCAs extend 300 feet slope distance from the 

stream channel. Class I and II RHCAs are 600 feet wide, including both sides of the stream 

channel. There are approximately 45 miles of Class I and II streams in the Spears project area. 

The RHCAs for these streams encompass 3,273 acres. 

Class III streams are perennial, non-fish-bearing streams and RHCAs extend 150 feet slope 

distance from the stream channel. Class III RHCAs are 300 feet wide including both sides of the 

stream channel. There are approximately 14 miles of Class III streams in the Spears project area. 

The RHCAs for these streams encompass 509 acres. 

Class IV streams are seasonally flowing, or intermittent and RHCAs extend 50 feet slope 

distance. There are approximately 63 miles of Class IV streams and Class IV RHCAs 

encompass approximately 764 acres in the project area. 

The amount and type of vegetation in riparian areas plays an important role in the maintaining 

and improving both water quality and fish habitat. The increasing amount of conifers in RHCAs 

prevents woody vegetation such as alder, willow, aspen, and shrubs from expanding. Conifers 

within RHCAs compete with these species for nutrients. Many of these broadleaf species are 

shade-intolerant; throughout the project area conifers are competing with and shading these 

brushy, shrubby species, and they are losing vigor. The roots of woody vegetation help to 

stabilize streambanks and the stems act as a roughness element that reduces the velocity and 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 77 

erosive energy of over bank flow during high water events. Conifers do not provide the same 

bank stabilizing function as these brushy, shrubby species. 

INFISH established landscape-scale interim Riparian Management Objectives (RMOs) that 

would be applied to watersheds with inland native fish. INFISH states that the interim RMOs 

would not be met instantaneously, but would be achieved over time. INFISH also recognized 

that all RMOs may not occur on a specific segment of stream within a watershed, but all should 

generally occur at the watershed scale for stream systems of moderate to large size (3rd to 6th 

order streams). There are no RMOs that specifically address riparian vegetation; however, 

riparian vegetation does affect pool frequency, water temperature, large woody debris, width-todepth ratios, and bank stability. All of the habitat features described in the interim RMOs are 

inter-related. 

The interim RMOs that apply to the Spears project area include pool frequency, water 

temperature, large woody debris, and width-to-depth ratios. The interim RMOs for bank stability 

and lower bank angle only apply to non-forested systems; the Spears project area is a forested 

system and these RMOs do not apply. Additional discussion is contained in the January 2007 

Spears Resource Report and Biological Evaluation for Aquatic Species. 

Pool Frequency 

The frequency and area of pools is dependent on stream gradient and drainage area, generally as 

stream size (order) increases, pools become larger but more infrequent. In smaller order 

channels, large wood in the stream channel increases pool frequency (Montgomery and 

Buffington 1993). Pool depth and complexity is also a function of the abundance of woody 

debris and sediment routing. Large pulses of sediment moving through a stream system can 

restrict pool depth and ultimately limit habitat capability. The bankfull width-to-depth ratio, a 

primary indicator of channel dimension, is also directly related to both pool quantity and quality. 

An inverse relationship between stream width and pool spacing has been well documented by 

Rosgen (1996). The number of pools per mile increases as the stream channel narrows as shown 

in Table 30. 

Table 30. Interim objectives for pool frequency in INFISH. 

Wetted width (feet) 10 20 25 50 75 100 125 150 200 

Pools per mile 96 56 47 26 23 18 14 12 9 

Marks Creek is lacking pool structure. Level II steam surveys completed in 1999 in Marks 

Creek indicated that pools averaged 20.01 per mile. Average number of pools for 25 feet wetted 

width from INFISH is 47 pools per mile. On Nature Creek, there were 42.24 pools per mile. 

Nature Creek is moving towards meeting the objective of 47 as described in INFISH. Because 

similar conditions have been observed on other streams within the project area, the findings from 

these stream surveys are assumed to apply throughout the project area. Therefore, the streams in 

the project area are assumed to have fewer pools than indicated by the INFISH interim RMOs. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 78 

Water Temperature 

The interim objective for water temperature is to not increase the maximum water temperature 

based on a 7-day average and to have maximum water temperatures below 59 degrees Fahrenheit 

in adult holding habitat and 48 degrees Fahrenheit within spawning and rearing habitats. 

Currently, water temperature monitoring in the project area indicates that the 7-day average 

temperatures exceeds the RMO for water temperature. Water temperatures are discussed later in 

this chapter in the section on water quality. 

Large Woody Debris 

Large woody material in streams and the adjacent flood plain provides streambank stability, 

decreases flow velocities, increases storage time (decreases downstream flood risk), cools water 

temperature, and stores sediment. Large woody debris (i.e. down trees) also appears to reduce 

grazing and browsing impacts on bank stability by reducing accessibility to the riparian 

vegetation. Large wood helps to form pools in the stream channel. 

Based on stream surveys, the project area is deficient in the amount of large woody material in 

streams. Large woody material provides aquatic habitats and shade for streams. Redband trout, 

like many other salmonids, have evolved in stream systems in which large woody material helps 

retain organic and inorganic particulate matter that is important for channel stability, biological 

diversity, and productivity (Nakamura and Swanson 1993). Large wood influences habitat for 

fish and other aquatic organisms by serving as energy dissipaters, flow deflectors, and dams. 

Large trees are needed in RHCAs because they become large woody material when they fall. In 

the Spears project area, there is less large woody debris than the amount indicated by the RMO. 

Table 31 displays the desired amounts of large woody debris, by size, and the existing amounts 

based on the 1997 Level II stream survey. Desired amounts were determined from INFISH and 

a study of unmanaged, mixed conifer, Blue Mountain streams (Cordova 1995). 

Table 31. Existing amount of large woody debris compared to objective.

>12 inches dbh, >35 feet long 1.3 - 1.7 1.49 

>6 inches dbh, >35 feet long 3.4 - 4.5 2.32 

Width-to-depth Ratio 

The width-to-depth ratio is often used as an index of cross-sectional shape, where both width and 

depth are usually measured at the bankfull level. Both depth and width can respond rapidly to 

changes in sediment load and/or discharge. Whether a stream erodes downward or outward is 

influenced by both local shear stresses and whether the bed or banks are the most easily eroded. 

Bank vegetation increases the resistance to erosion through its binding effects on banks, with 

erosion decreasing as the percentage of roots in the soil increases, and this leads to narrower 
Chapter 3 - Affected Environment and Environmental Consequences

channels than would otherwise be expected. The effect of vegetation on channel shape is more 

pronounced in smaller streams (Gordon et al. 1992).

Changes in width-to-depth ratios are a result of wood recruitment within RHCAs, sediment 

delivery, and bank stability. Wood embedded in the stream channel and streambanks narrows 

the channel, slows velocity, catches sediment, and creates pools. Showing an improvement in 

large wood recruitment will result in improvement in width-to-depth ratios. Narrower deeper 

stream channels result in cooler water temperatures improving habitat for fish. 

The interim RMOs for width-to-depth ratios are less than 10. Bottom Line Stream surveys 

indicate that the width-to-depth ratio for Marks Creek is 13.63. 

Environmental Consequences 

Alternative 1 

No activities would occur in RHCAs. In many places, high densities of conifers within the 

RHCAs would continue to inhibit the growth of deciduous, broadleaf species such as alder, 

willow, aspen, and cottonwood. The existing conifers in RHCAs would continue to compete for 

nutrients with broadleaf species and other conifers. Because of competition, conifers would 

grow at slower rates and trees (future large woody debris) would be smaller in diameter than 

would be expected in less dense stands. 

Since the Forest Plan was signed in 1989 and again when INFISH was signed in 1995, the 

Ochoco National Forest has been managing riparian areas to maintain or improve riparian 

conditions. Because of protection of streams, meadows, seeps, springs, and riparian areas over 

the last 15+ years, pools have been improving. Large woody material increased as a result of 

budworm mortality in the late 1980’s and early 1990’s. Wood recruitment inside the Hash Rock 

Fire (2000) perimeter will improve the pool structure as some of the dead trees fall into the 

creeks from weather events such as wind. Recruitment of large wood outside the fire area as a 

result of beetle-killed trees is also expected to improve pool numbers when dead trees inside 

RHCAs begin to fall in the next 5 to 10 years. Over time, pool numbers are expected to increase 

and width-to-depth ratios are expected to decrease, providing cooler water and cover. Large 

wood from logs would also catch sediment. Riparian vegetation that has been planted along 

streams in the fire perimeter would help stabilize pools, increase cover, decrease width-to-depth 

ratios, and reduce water temperatures. 

Alternatives 2, 3, 4, and 5 

Several activities have been proposed within RHCAs to increase the vigor of riparian vegetation 

and contribute to recruitment of future large woody material. Table 32 summarizes the proposed 

activities within RHCAs. Tables 33 through 38 provide a breakdown of activities within RHCAs 

by stream, stream class, and alternative. Streams identified as “trib” are unnamed tributaries to 

the named stream.

Alternative 3 is not displayed in Table 33 because no commercial harvest would occur in that

Commercial harvest is proposed in the outer portions of RHCAs in Alternatives 2, 4, and 5. In 

Class I and II RHCAs, no harvest would occur within 200 feet of the stream channel. In Class 

III RHCAs, no harvest would occur within 50 feet of the stream channel. In Class IV RHCAs, 

no harvest would occur within 25 feet of the stream channel. Because of the distance to the 

stream, commercial harvest by itself in Class I and II RHCAs would have negligible effects to 

the RMOs. However, commercial harvest is combined with precommercial thinning and 

underburning to promote attainment of RMOs for pool frequency, water temperature, large 

woody debris, and width-to-depth ratios. Commercial harvest in the outer portions of the 

RHCAs would reduce tree densities and increase the growth of the residual trees. When 

combined with precommercial thinning, increased tree growth is also expected in the inner 

portion of the Class I and II RHCAs. Larger trees that become large wood in the outer portions 

of Class I and II RHCAs are unlikely to reach the stream channel, but large trees within the inner 

portions of these RHCAs would increase future recruitment of large woody material. In Class III 

and IV RHCAs, larger trees in the outer portion of the RHCAs are more likely to reach stream 

channels because larger trees may be as tall as 100 feet and could fall directly into the stream 

channel. Within RHCAs, commercial harvest would promote the development of larger trees 

and future large wood recruitment. 

Commercial harvest in Class III and IV RHCAs would benefit riparian-associated trees and 

shrubs such as cottonwood, aspen, alder, and willow by reducing competition for nutrients and 

growing space. These treatments would contribute to future large woody debris recruitment, 

pools, decreased width-to-depth ratios, and reduced water temperature. In the future, when large 

trees fall into streams they would improve pool numbers which would reduce stream 

temperatures. Increases in riparian vegetation would contribute to bank stability and capture 

sediments, contributing to narrower streams and decreased width-to-depth ratios.

No heavy machinery or off road vehicles would be used in the RHCAs for commercial harvest, 

except on existing roads. Design elements to reduce ground disturbance within RHCAs such as 

winch lining, and locating landings outside of RHCAs would minimize sediment. Residual slash 

and the unharvested areas are expected to filter sediment before it reaches the streams. 

Alternative 3 would have no effect from commercial harvest activities. 

Precommercial thinning is proposed in RHCAs in all action alternatives. Precommercial 

thinning would occur to within 5 feet of stream channels. No heavy machinery or off road 

vehicles would be used in the RHCAs to implement this activity. Understory trees (typically less 

than 9 inches dbh) would be thinned to approximately 16 to 18 foot spacing. The heights of trees 

at various slopes and distances that provide shade during the period when peak temperatures 

occur were calculated. Only trees less than the height indicated would be removed so that the 

existing amount of stream shade is maintained. Removing these conifers would result in more 

sunlight to deciduous vegetation which, in turn, would result in more vigorous deciduous 

vegetation. This activity would have similar effects as commercial harvest by reducing 

understory tree density and reducing competition. The growth rate of residual trees would 

increase, promoting future large woody debris. Thinning would reduce the competition between 

riparian-associated species and conifers resulting in more woody, shrubby species. 

Precommercial thinning would result in increased growth rates for both conifers and riparian 

vegetation. Precommercial thinning would promote attainment of RMOs in RHCAs (Class IIV). In the future, when large trees fall into streams they would increase pool numbers and help 

reduce stream temperatures. Increases in riparian vegetation would contribute to bank stability 

and capture sediments, contributing to narrower streams and decreased width-to-depth ratios. 

Prescribed underburning is proposed within RHCAs in all action alternatives. Ignition would not 

occur within 50 feet of the streams; however, fire would be allowed to burn within 50 feet of the 

stream. Prescribed fires are expected to burn in a mosaic pattern in the RHCAs with an objective 

of burning about 20 percent of the area at a low-intensity level. Project design criteria have been 

established to retain large woody debris and for the construction of firelines in RHCAs. Burning 

within the RHCAs would reduce stand density and remove ladder fuels by killing small seedling 

and sapling sized trees. Burning is also expected to consume surface fuels such as leaves, 

needles, limbs, and branches that have fallen. Like the other activities, the reduced competition 

is expected to rejuvenate riparian-associated species, increasing riparian species composition and 

abundance. Increased riparian species would improve bank stability and shade which would 

promote attainment of RMOs in the future, particularly the RMOs for width-to-depth ratio and 

stream temperature. Some large woody debris is expected to be consumed during burning 

activities; however, burning activities would be designed to minimize consumption of large 

down wood. While some large wood may be consumed, fire is expect to kill some standing trees 

that over time would fall and become large woody debris. Reducing competition promotes the 

growth of residual trees that will be future large woody debris. 

Hardwood thinning activities are proposed within RHCAs in all action alternatives. Conifers 

would be cut and left on the ground or lopped and scattered. These thinning activities would 

occur in aspen and cottonwood stands and reduce the amount of conifers that are competing with 

these hardwood species. As a result, aspen and cottonwood clones would be expected to be 

maintained or increased in extent and vigor. Shade is expected to increase in these stands as the 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 85 

hardwood species increase in size as a result of reduced competition. Increased levels of shade 

would contribute to lower stream temperatures. 

Hand piling of thinning slash with RHCAs is planned in all action alternatives. This treatment 

would have no effects on RMOs for pool frequency, water temperature, large woody debris, or 

width-to-depth ratio. The hand piled material is small diameter slash that would not provide 

large woody debris to the stream and therefore would have no effect on pool formation and 

reduced water temperatures resulting from pools. 

Road work is proposed in RHCAs in Alternatives 2, 4, and 5. Table 37 displays the amount of 

road construction by alternative. Table 38 displays the amount of road reconstruction, closures, 

and decommissioning. Alternative 3 does not propose any road work and is not included in 

Tables 37 and 38. Under Alternative 3, roads within RHCAs are expected to continue to 

transport sediment to streams, particularly to Crystal, Marks, Peterson, Rush, Salmon, and 

Wildcat Creeks. 

Road work, including constructing, reconstructing, closing, and decommissioning, affects 

sediment delivery to streams. The construction of new road within RHCAs would increase the 

potential for sediment delivery to streams. New roads would provide additional soil disturbance 

and potential for sediment transport. Construction of roads in the Salmon Creek RHCA would 

not increase sedimentation to Salmon Creek because the new construction would be above an 

existing road that effectively blocks sediment from entering Salmon Creek. 

Closing and decommissioning roads within RHCAs would reduce compaction, increase 

infiltration, and improve road drainage which would reduce concentrated flows and sediment 

transport. Reconstruction of roads within RHCAs would improve drainage and reduce 

sedimentation from the existing condition. Existing roads within RHCAs known to be chronic 

sources of sediment include road 3300-504 along Salmon Creek and road 2630-013 near Crystal 

Creek. Both of these roads would be reconstructed which would reduce the amount of sediment 

entering these streams. Additionally, two culverts would be removed on Rush Creek and 

portions of Road 2620-030 would be decommissioned. These actions would eliminate the 

chronic sediment production from the two undersized culverts.

The net result is that Alternatives 2, 4, and 5 would result in a reduction of open roads in RHCAs 

and an improvement over current conditions by reducing compaction, improving road drainage, 

and reducing the amount of sediment produced by roads. During the short term, prior to 

vegetation becoming established on scarified road surfaces, there may be an increase in sediment 

production from road closure, decommission, and reconstruction activities. However, with 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 86 

drainage and outsloping, sediment reaching the streams is expected to be minimal. Work would 

normally occur during the summer months when stream flows are low. However, small pulses 

of sediment may occur if a rain event immediately followed road work. The rain event would 

increase flow in the stream and sediment would be dispersed throughout the system.

None of the proposed activities would immediately result in meeting RMOs for pool frequency, 

water temperature, large woody debris, or width-to-depth ratio. However, these activities would 

promote attainment of RMOs in the future. 

Cumulative Effects 

The cumulative effect of past, present, and reasonably foreseeable actions is expected to be 

improved RHCA function and condition. RHCAs in which the proposed activities overlap with 

past, present, or reasonably foreseeable actions include Cornez, Jim Elliott, Little Hay, Marks, 

McGinnis, Reilly, and Rush Creeks. 

The Hash Rock Fire burned the upper reaches of Cornez, Hamilton, McGinnis, and Reilly 

Creeks in the summer of 2000. The fire removed ground cover, riparian vegetation, and large 

woody debris. Immediately after the fire, there was a high risk of bank erosion and channel 

widening. Since that time, vegetation has reestablished. Large wood recruitment is now 

occurring as fire-killed trees fall into streams. Precommercial thinning and prescribed burning 

activities within the RHCAs of these streams by the action alternatives would contribute towards 

the development of future large woody debris by increasing the growth rates of residual trees. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 87 

As a result, these activities promote future recruitment of large woody debris. Hardwood 

thinning in the RHCAs of Cornez and McGinnis Creeks would promote increased riparian 

vegetation and increased shade. Post-fire work in these areas to stabilize stream systems 

included both riparian planting and replacing undersized culverts on McGinnis Creek, Reilly 

Creek, and the east and west forks of Hamilton Creek; replacing two undersized culverts on 

Cornez Creek, and decommissioning approximately 0.4 miles of road on McGinnis Creek. 

Precommercial thinning and prescribed burning along these streams would complement riparian 

planting that has already occurred, contributing to increased hardwood species composition and 

abundance. Road closure and decommission on Cornez Creek, Reilly Creek, and tributaries to 

McGinnis Creek would complement previous road decommission and culvert replacements 

along these streams. Sediment production from roads and culverts is expected to decrease along 

these streams. The cumulative effect of these treatments is to promote attainment of RMOs for 

pool frequency, water temperature, large woody debris, and width-to-depth ratios. 

Activities that have occurred in the RHCAs of Jim Elliott, Little Hay, Marks, and Rush Creeks 

include road decommissioning along Jim Elliott Creek; headcut stabilization, riparian planting, 

and fencing on Little Hay Creek; riparian planting, stream channel restoration, and road 

decommissioning along Marks Creek; and riparian planting along Rush Creek. Commercial 

harvest, precommercial thinning, prescribed burning, hardwood thinning, and road work along 

these streams would also contribute toward the attainment of RMOs for pool frequency, water 

temperature, large woody debris, and width-to-depth ratios. 

Livestock grazing would continue. The Marks Creek, Wildcat, Burn, and Crystal Springs 

allotments overlap the Spears project area. Historic grazing contributed to the removal of 

deciduous woody vegetation and compaction of alluvial terraces. Livestock grazing levels have 

been reduced from historic and riparian vegetation has since improved. Activities within 

RHCAs would likely attract livestock because removing small trees and surface and ladder fuels 

would remove barriers to livestock movement. Increasing sunlight to the ground by removing 

conifers would also increase growth of grasses and shrubs. This would increase the amount of 

forage available which would also attract livestock. Livestock are expected to continue to use 

riparian areas and are expected to consume some of the increased forage. Livestock use of 

riparian areas is not expected to increase because activities in the uplands are expected to 

increase forage and remove barriers to livestock movement similar to the activities in the 

RHCAs. Also, livestock grazing permits include provisions for distributing livestock or moving 

livestock from pastures when certain triggers are reached. Triggers include bank trampling and a 

switch to preference for woody species. Livestock are expected to be moved when triggers are 

reached. Where hardwood thinning activities occur in RHCAs, livestock are not expected to 

utilize these areas because some fences and cages would be constructed and slash would be 

arranged to discourage livestock use. 

Aquatic Species 

Essential Fish Habitat 

The Pacific Fishery Management Council designated Essential Fish Habitat (EFH) for Chinook 

salmon on September 27, 2000. This designation included current and some historic habitat in 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 88 

the Deschutes Basin. Historical habitat above Pelton Round Butte Dam was included. Historical 

habitat located above Ochoco Reservoir Dam was not included because the dam does not allow 

fish passage. The Spears project area is upstream from Ochoco Reservoir Dam and is not 

considered EFH. Therefore, this project would have no effect on EFH. 

Management Indicator Species 

The Forest Plan identified Management Indicator Species (MIS) to determine the effects of 

management activities on fish and wildlife habitat. Management indicator species are species 

whose presence in a certain location or situation at a given population level indicates a particular 

environmental condition. Population changes are believed to indicate effects of management 

activities on a number of other species. 

Rainbow trout (Oncorhynchus mykiss) and brook trout (Salvelinus fontinalis) were picked as 

indicators of riparian and aquatic habitat. In the past, these fish were stocked by the Oregon 

Department of Fish and Wildlife. They are no longer stocked in the streams in the project area, 

but naturally reproduce in many streams. These trout species can be found in the same streams 

where redband trout are found. Effects to brook and rainbow trout habitat would be the same as 

the effects described for redband trout habitat in the section on threatened, endangered, and 

sensitive species. 

Threatened, Endangered, and Sensitive Species 

Affected Environment 

Two aquatic species federally listed as threatened are known to occur on the Ochoco National 

Forest. These species are: bull trout (Salvelinus confluentus) and Mid-Columbia River steelhead 

trout (Oncorhynchus mykiss ssp.). There are no endangered aquatic species on the Ochoco 

National Forest. Several species from the R-6 Regional Forester’s sensitive species list are 

known to occur on the Ochoco National Forest and include: redband trout (Oncorhynchus 

mykiss ssp.), Malheur mottled sculpin (Cottus bairdi), west slope cutthroat trout (Oncorhynchus 

clarki lewisi), Columbia spotted frog (Rana luteiventris), and Mid-Columbia River spring 

Chinook salmon (Oncorhynchus tshawytscha). 

This project would have no effect to the Mid-Columbia River steelhead trout or Mid-Columbia 

spring chinook salmon because dams constructed downstream of the project area on the Crooked 

and Deschutes Rivers, and Ochoco Dam on Ochoco Creek prevent anadromous fish from 

accessing streams in the project area. There would be no effect to the bull trout, Malheur 

mottled sculpin, or west slope cutthroat trout because they are not known to exist in the project 

area or there is no habitat for the species in the project area. The January 2007 Resource Report 

and Biological Evaluation for Aquatic Species contains additional information on threatened, 

endangered, and sensitive aquatic species. 
Chapter 3 - Affected Environment and Environmental Consequences

Redband Trout 

The redband trout is known to occur throughout the project area. There are 45 miles of fishbearing streams (Class I or II) in the project area: 36 miles are on National Forest System lands 

and 9 miles are on private lands. Map 3 displays the streams that are occupied by redband trout. 

The redband trout is a stream spawner, normally spawning in the spring (March through June). 

The eggs usually hatch in 4-7 weeks and alevins (pre-emerging fish) take an additional 3-7 days 

to absorb the yolk before becoming free-swimming. The average age at first spawning is 2-3 

years, but some wild populations do not spawn until they are age 5. Gravel embeddedness of 

less than 20 percent is essential to maintain healthy salmonid population, especially in those 

areas identified as potential or existing spawning areas (Bjorn and Reiser 1991). 

Redband trout populations are currently depressed. However, existing populations are generally 

in fair condition, based on age distribution and condition factor (ODFW 1991). The combination 

of habitat modification, low summer flows, high summer stream temperatures, lack of suitable 

riparian vegetation (due to roads in RHCAs, stream down cutting, conifers shading hardwood 

species, and livestock browse), and increase in sediment (due to roads built within RHCAs) has 

affected redband trout populations in the project area. Sediment has been found to fill spawning 

gravels resulting in lower numbers of fry emergence, lower oxygen levels, and change in food 

sources and habitat features. 

Redband trout have evolved in stream systems in which large woody debris helps retain organic 

and inorganic particulate matter that is important for channel stability, biological diversity, and 

productivity (Nakamura and Swanson 1993). Large woody debris influences habitat for fish and 

other aquatic organisms by serving as energy dissipaters, flow deflectors, and dams. As large 

wood accumulates it forms pools in the stream channel. The deep water of the pools lowers 

water temperature. Fish use pools for hiding cover, to seek refuge in cooler water during the 

summer months, and as resting areas while feeding. 

Temperatures of 60 degrees F are considered ideal for rapid growth of rainbow trout (Leitritz and 

Lewis 1980). In the Spears project area, temperatures are likely below 56 degrees F for the 

months of October to March prior to spawning. Females are most productive when they are in 

water where temperatures do not exceed 56 degrees F for 6 months before spawning (Leitritz and 

Lewis 1980). Water temperatures in the high 70’s, except under otherwise ideal conditions, may 

cause stress, which predisposes disease or in some cases, death for all age classes. Redband trout 

are most successful in habitats with temperatures of 70 degrees or slightly lower, but can survive 

if there is cooler, well-oxygenated water into which they can retreat as the surface waters warm 

over 70 degrees F. The 7-day maximum average temperatures in Marks Creek average as high 

as 75.6 degrees F. Naturally occurring temperatures in some tributaries also exceeded State 

standards. In the summer, stream temperatures often reach levels that retard the growth of and 

stress redband trout. Streamside vegetation such as willow, alder, and aspen is important for 

providing shade in the summer and insulation in the winter. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 90 

Streams in the project area have a low number of pools. In a channel with a low number of 

pools, the ratio of surface area to volume of water is high, and water in the channel tends to heat 

and cool rapidly. This causes variations in daily temperatures as much as 15 to 20 degrees F. 

Large pulses of sediment moving through a stream system can restrict pool depth and ultimately 

limit habitat capability. Fine sediments degrade spawning gravels and spawning success by 

filling the spaces between rocks, reducing the oxygenation and survival of eggs. 

Erosion from previous activities in the project area such as timber harvest, road construction, and 

grazing have caused sediment input into streams and has also reduced the reproductive success 

of redband populations. The Hash Rock Fire in 2000 removed ground cover and riparian 

vegetation in the upper reaches of Hamilton, Cornez, Reilly, and McGinnis Creeks. Since then, 

vegetation has been reestablished in the fire area as a result of sprouting and planting. Increases 

in vegetation help stabilize streambanks, filter sediment, reduce water temperature, provide 

hiding cover, and improve width-to-depth ratio. 

Habitat features of the redband trout that may be directly affected by the proposed activities 

include large woody debris (LWD), stream shade, and sediment delivery to streams. Effects to 

these features, in turn, affect pool frequency and depth, water temperature, and width-to-depth 

ratios. 

Columbia Spotted Frog 

Columbia spotted frogs inhabit a variety of vegetation communities, including coniferous or 

mixed forests, grasslands, and riparian areas of sage-juniper brush lands. Historically, Columbia 

spotted frogs were found at elevations ranging from near sea level to 7,370 feet. Although no 

formal surveys have been conducted, Columbia spotted frogs are known to occur in the project 

area. 

Dumas (1966) reported that relative humidity of less than 65 percent is lethal to adult spotted 

frogs in approximately 2 hours, a factor which would restrict spotted frogs to higher elevations or 

moist riparian zones in arid western landscapes. Because both breeding and over-wintering 

occur at aquatic sites, populations are located in the general vicinity of ponds, lakes, springs, 

and/or streams. A study in arid southwestern Idaho (Munger et al. 1998) found adult spotted 

frogs were associated with palustrine, shrub-scrub, intermittent riverine, streambed, or seasonally 

flooded sites. Frogs were also associated with vegetation indicating permanent water sources 

(i.e., willows and submerged aquatic plants rather than with emergent vegetation such as sedges) 

and vegetation providing hiding and thermal cover (e.g., willows). Spotted frogs are located in 

similar habitats in the project area. 

Summer foraging may occur at the same water body used for breeding and over wintering, but in 

many cases frogs move to other areas. Spotted frogs move to other sites in summer for a variety 

of reasons including predator avoidance and the attractions of more abundant food and less 

competition (Bull and Hayes 2001). Foraging sites include ephemeral pools in forests and 

meadows, streams (permanent and intermittent), river edges, riparian zones, temporary and 

permanent ponds, lake margins, and marshes. Sites used for summer foraging only in the Idaho 

mountains included all types of wetland habitats and were on average smaller and shallower than 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 91 

wetlands used for breeding and wintering, with less forest or shrub cover along shorelines 

(Pilliod et al. 2002). Patla (1997) found that “spotted frogs demonstrate considerable plasticity 

in summer foraging habitat, making use of small wet or damp areas in forest and meadows, 

including water-filled tire tracks, stream edges, and marshes.” 

Wintering habitat includes ponds, streams, under stream banks, springs, beaver dams, and 

underground areas (associated with water bodies), but all such sites must have above freezing 

temperatures, be moist or wet, and be well oxygenated. Columbia spotted frogs winter in or 

immediately adjacent to aquatic sites, where they can avoid the threat of freezing or oxygen 

depletion (Bull and Hayes 2002). 

Environmental Consequences 

Redband Trout 

The definition for adverse effects in INFISH (1995) was utilized in the fisheries analysis. This 

definition states “adverse effects include short- or long-term, direct or indirect management 

related impacts of an individual or cumulative nature, such as mortality, reduced growth, or other 

adverse physiological changes; harassment of fish; physical disturbance of redds; reduced 

reproductive success; delayed or premature migration; or other adverse behavioral changes.” 

Management related impacts to large woody debris, stream shade provided by vegetation, and 

sediment delivery resulting from the proposed activities were evaluated to determine the degree 

of effects to redband trout. Evaluation of these variables also indicates the effects to the RMOs 

describing good fish habitat, including pool frequency, large woody debris, and width-to-depth 

ratios. Bank stability and lower bank angle are not further discussed because these RMOs apply 

to non-forest systems. The Spears project area is a forested system. 

Alternative 1 

There are no activities proposed in Alternative 1 that would directly alter redband trout habitat. 

In many places, high densities of conifers within the RHCAs would continue to inhibit the 

growth of deciduous, broadleaf species such as alder, willow, aspen, and cottonwood. Conifers 

in RHCAs would continue to compete for nutrients with broadleaf species, as well as other 

conifers. Because of competition, conifers would grow at slower rates and trees (future large 

woody debris) would be smaller diameter than less dense stands. In open canopy areas where 

woody vegetation is present along streambanks, shade would increase. Increasing shade over 

streams contributes to reducing water temperature and acts as hiding cover for redband trout. 

Large woody material has been increasing as a result of budworm mortality in the late 1980’s 

and early 1990’s. Wood recruitment inside the Hash Rock Fire (2000) perimeter will improve 

the pool structure as some of the dead trees fall into the creeks from weather events such as 

wind. Recruitment of large wood outside the fire area as a result of beetle-killed trees is also 

expected to improve pool numbers when dead trees inside RHCAs begin to fall in the next 5 to 

10 years. Over time, pool numbers are expected to increase and width-to-depth ratios are 

expected to decrease, providing cooler water and cover. Large wood is also expected to catch 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 92 

sediment. Riparian vegetation that has been planted along streams in the fire perimeter will help 

stabilize pools, increase cover, decrease width-to-depth ratios, and reduce water temperatures. 

Road 3300-504 along Salmon Creek would continue to be a chronic sediment source. Two 

culverts on Rush Creek would also continue to be a chronic sediment source. Gravel 

embeddedness of less than 20 percent is essential to maintain healthy salmonid population, 

especially in those areas identified as potential or existing spawning areas (Bjorn and Reiser 

1991). If sediment exceeds 20 percent, the spaces between the rocks in the substrate are filled 

and oxygenation of eggs is reduced. Reduced oxygenation results in reduced success of fish and 

frog eggs surviving. Salmon Creek along Forest Road 3300-504 and the undersized culverts on 

Rush Creek would continue to contribute sediment into Salmon Creek and Rush Creek, which 

would reduce the suitability of spawning habitat in these areas. 

This alternative would have no impact on redband trout or its habitat. 

Alternatives 2, 3, 4, and 5 

The analysis for redband trout focused on activities within Class I and II RHCAs because 

redband trout are found within Class I and II streams. Activities proposed in the action 

alternatives that occur outside of RHCAs would have negligible effects to the redband trout. The 

RHCA buffers would protect streams from sediment inputs and provide for other riparian 

functions including the delivery of organic matter and woody debris, stream shading, and bank 

stability (INFISH pp. A-4). Sedimentation that may result from activities in the uplands, such as 

timber harvest, precommercial thinning, fuels treatments, and road work would be filtered by 

ground vegetation and slash in both the treated areas and RHCA. Activities occurring within the 

RHCAs of Class III and IV streams would also have negligible effects to the redband trout, 

because these streams are non-fish bearing or intermittent. While Class III and IV streams 

provide water to fish-bearing streams and could transport sediment downstream, the no harvest 

areas within RHCAs would minimize sediment delivery to streams. Precommercial thinning and 

underburning activities are not expected to result in more than background levels of sediment 

because slash and ground vegetation would help filter sediment and underburning activities 

would occur during spring and fall when vegetation is more moist and less likely to burn. 

Commercial harvest would occur in the outer 100 feet of Class I and II RHCAs in Alternatives 2, 

4, and 5. The amount of commercial harvest ranges from a high of 101 acres in Alternative 2, to 

87 acres in Alternative 4, and a low of 67 acres in Alternative 5. Table 33 displays the amount of 

commercial harvest by stream name and stream class. With a few exceptions, ground-based 

machinery for harvest would not occur in RHCAs. No grapple piling would occur in RHCAs. 

Units 104 (Salmon Creek) and 559 (Marks Creek) have existing roads within the RHCAs that 

would be reused during harvest operations. These roads effectively block sediment from the 

harvest activity from entering Salmon Creek or Marks Creek. There would be negligible effects 

to the redband trout from commercial harvest in the outer 100 feet of Class I and II RHCAs, 

because harvest would not occur within 200 feet of the stream channels. Stream shade and water 

temperature would be unaffected by commercial harvest because none of the trees removed from 

the outer portion of the RHCAs provide shade. Sediment from commercial harvest would be 

filtered by existing ground vegetation in the 200-foot non-treated area. Reshin et al. (2006) 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 93 

found that a 32.8-foot (10 meter) setback of felling and yarding activities prevented sediment 

delivery to streams from about 95 percent of harvest-related erosion. Large wood from the outer 

portions of these RHCAs would not be expected to reach the stream channel. Pool frequency 

would be unaffected. 

Precommercial thinning would occur within 5 feet of the stream channel in Class I and II 

RHCAs. The amount of precommercial thinning in Class I and II RHCAs ranges between 534 

and 582 acres in the action alternatives. Table 35 identifies the amount of precommercial 

thinning by alternative and by stream class. Understory trees (typically less than 9 inches dbh) 

would be thinned to approximately 16 to 18-foot spacing which would promote growth of the 

remaining trees; increasing the diameter and number of trees that may reach sizes for future large 

wood (>21 inches dbh). Future large wood recruitment would improve fish habitat by creating 

pools and hiding cover. Water temperatures would decrease from increased numbers of pools. 

Competition between conifers and riparian-associated species would be decreased, increasing 

hardwood species composition and abundance. Increased abundance of riparian species would 

increase bank stability and reduce erosion because of the deeper root systems of these species. 

They would also provide increased stream shade. Thinning trees within RHCAs would 

contribute to improved redband trout habitat in the future by increasing riparian shrubs which 

provide cover, bank stability, and stream shade. No heavy equipment or OHVs would be used 

during precommercial thinning activities so there would be minimal ground disturbance from 

this activity. Ground vegetation, as well as the slash resulting from precommercial thinning 

would filter any sediment from the thinning activity. There would be little or no disturbance to 

fish or fish habitat during implementation of this activity. Fish would move to another part of 

the stream and/or seek hiding cover if some activity in the RCHA was a minor disturbance just 

as they would when deer cross the stream or feeds in the RHCA. 

Prescribed underburning would occur within RHCAs. Within Class I and II RHCAs, the amount 

of burning by alternative varies between 950 and 1,040 acres. Table 36 displays the amount of 

burning by stream, stream class, and alternative. Burning within the RHCAs would reduce 

ladder fuels by killing small seedling and sapling sized trees. Like the other activities, the 

reduced competition is expected to increase growth of residual trees and rejuvenate riparianassociated species, increasing riparian species composition and abundance. Large woody debris 

may be consumed during burning; however, design criteria have been developed to minimize 

consumption of large down wood. While some large wood is expected to be consumed, fire is 

also expected to kill some standing trees that over time would fall and become large woody 

debris. Reducing competition also promotes the growth of residual trees that will be future large 

woody debris. Prescribed burning activities are expected to result in minimal amounts of 

sediment because (1) burning would occur during spring and fall when conditions are moist and 

burn intensity would be light, (2) consumption of live vegetation and large diameter wood would 

be minimal, (3) not all units in a single drainage would be burned in the same year, and (4) 

burning activities would occur over a 10-year period. 

Hand piling of some thinning slash would occur within RHCAs. Piling would occur after 

thinning, usually before the fuels dry out. The piles would be burned in the late fall or early 

winter usually within 2 to 4 years. This sequence of activities retains ground cover to filter 

sediment. Slash piles can act as filters for sediment into streams immediately after treatment. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 94 

Large woody debris would be unaffected by this activity. The material that is piled is small 

diameter slash. Pool frequency and formation would be unaffected since large woody debris 

would not be affected. Water temperature would also be unaffected. 

Approximately 100 acres of hardwood thinning would occur within Class I and II RHCAs. In 

areas where hardwood thinning would occur, conifers are competing with aspen and cottonwood 

for nutrients, light, and growing space. Thinning conifers in these areas would improve the vigor 

of aspen and cottonwood. These species are expected to be maintained and increase in extent. 

Shade would increase with expansion of stream side hardwoods. Increased shade contributes to 

lower temperatures in streams. The felled conifers would be left for downed wood or would be 

lopped and scattered leaving slash on the ground. Some slash would be manipulated to protect 

seedlings from grazing and trampling. There would be no underburning in these areas. Some of 

the larger conifers would be girdled and would be retained as snags. This activity is expected to 

result in increasing numbers of aspen and cottonwood trees, which would increase shade within 

the RHCAs. Retaining slash would add filtering vegetation from upland sediment during rain 

events. 

Road work, including closing, decommissioning, reconstructing, and constructing, affect 

sediment delivery to streams. Alternatives 2, 4, and 5 would each construct approximately 300 

feet (0.06 miles) of new road in the RHCA of Salmon Creek. This is the only new road 

construction in Class I or II RHCAs. Construction of this road would provide additional soil 

disturbance and potential for sediment transport; however, the new construction would be above 

an existing road that effectively blocks sediment from entering Salmon Creek. Construction of 

this road would not affect habitat and spawning success of the redband trout. 

Alternatives 2, 4, and 5 propose to close, decommission, and reconstruct roads within Class I and 

II RHCAs. Table 39 displays the amount of road work within Class I and II RHCAs by 

alternative. Closing and decommissioning roads would reduce compaction and improve road 

drainage, reducing concentrated flows and sediment transport. Reconstruction of roads would 

improve road drainage and reduce sedimentation from the existing condition. Existing roads 

within Class I and II RHCAs known to be chronic sources of sediment include road 3300-504 

along Salmon Creek and road 2630-013 near Crystal Creek. Both of these roads would be 

reconstructed which would reduce the amount of sediment entering these streams. Additionally, 

two culverts would be removed on Rush Creek and portions of Road 2620-030 would be 

decommissioned. These actions would eliminate the chronic sediment production from the two 

undersized culverts. Reducing chronic sediment sources along Salmon, Rush, and Crystal 

Creeks would reduce sediment in these areas and improve spawning habitats for the redband 

trout. 

Prior to vegetation becoming established on scarified road surfaces, there may be an increase in 

sediment production from road closure and decommissioning activities. However, with proper 

drainage and outsloping, sediment reaching the streams is expected to be minimal. Work would 

generally occur during the summer months when stream flows are low and eggs produced during 

spawning (ranging from May to June) have hatched. During road work, fish can move to other 

parts of the stream and avoid any sediment. Small pulses of sediment may occur if a rain event 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 95 

immediately followed road work. The rain event would increase flow in the stream and sediment 

would be dispersed throughout the system and is not expected to adversely affect redband trout. 

Alternative 3 does not include any road work and would maintain the current conditions. Under 

Alternative 3, roads within the RHCAs of Class I and II streams are expected to continue to 

transport sediment to streams, particularly to Crystal, Marks, Peterson, Rush, Salmon, and 

Wildcat Creeks. Spawning habitat would continue to be degraded by sediment delivery from 

roads.

The determination for redband trout for Alternatives 2, 3, 4, and 5 is may impact individuals or 

habitat but would not cause a trend toward federal listing. The proposed activities would result 

in small amounts of sediment delivery to streams. However, fish would move out of the area of 

disturbance. Over time, sediment would be reduced as a result of increase in riparian vegetation 

from thinning and underburning in RHCAs. Fish habitat would be improved and fish 

populations would increase in the long term as a result of pool formation from large wood 

recruitment. 

Cumulative Effects 

Class I and II streams in which the effects of past, present, and reasonably foreseeable actions 

overlap in time and space include Cornez, Jim Elliott, Little Hay, Marks, McGinnis, Reilly, and 

Rush Creeks. Past actions including riparian planting, headcut stabilization, stream restoration, 

road closure and decommission, and culvert replacements have all contributed to improved 

riparian function and condition, including improvements in stream shade and sediment reduction. 

The difference in cumulative effects between the action alternatives is negligible. The 

cumulative effects of Alternatives 2, 3, 4, and 5 are the same for Jim Elliott, McGinnis, and 

Reilly Creeks. Cumulative effects are very near the same on Cornez, Little Hay, and Marks 

Creek (+/- 15 acres between alternatives). In all cases, the cumulative effects are expected to be 

beneficial to the redband trout. Closing, decommissioning, and reconstructing roads in the 

RHCAs of Jim Elliott, Marks, Reilly, and Rush Creeks is expected to reduce sediment transport 

to these streams. Hardwood thinning, precommercial thinning, and prescribed burning within 

the RHCAs of Marks, McGinnis, Reilly, and Rush Creeks would complement riparian planting 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 96 

that previously occurred along these streams, contributing to increased stream shade. These 

activities would also promote the growth of residual trees which would be a source of future 

large wood recruitment that would contribute to the development of pools, further adding to 

reduced water temperatures and sediment reduction. 

The livestock grazing within Class I and II RHCAs is expected to continue at the current levels. 

Precommercial thinning and underburning activities would remove barriers to livestock 

movement and are likely to increase forage as a result of increased sunlight and nutrients. 

Livestock use of riparian areas is not expected to increase because activities in the uplands are 

expected to increase forage and remove barriers to livestock movement similar to the activities in 

the RHCAs. Also, livestock grazing permits include provisions for distributing livestock or 

moving livestock from pastures when certain triggers are reached. Triggers include bank 

trampling and a switch to preference for woody species. Livestock are expected to be moved 

when triggers are reached. Where hardwood thinning activities occur in RHCAs, livestock use 

in these areas would be small because some fences would be constructed and slash would be 

arranged to discourage livestock use. 

Columbia Spotted Frog 

Alternative 1 

There are no activities proposed in Alternative 1 that would directly alter spotted frog habitat. 

In open canopy areas where woody vegetation is present along streambanks, shade would 

increase. Increasing shade over streams contributes to reducing water temperature and acts as 

hiding cover for Columbia spotted frogs. 

This alternative would have no impact on Columbia spotted frog or its habitat. 

Alternative 2, 4, and 5 

Harvesting trees would not contribute to changes in frog habitat. Ponds, seeps, and wet areas 

that may be used by frogs are included within RHCAs (INFISH 1995) and harvest would not 

occur within 25 feet. 

Precommercial thinning would occur on up to 900 acres within RHCAs. The amount varies by 

alternative and is displayed in Table 32. No heavy equipment or OHVs would be used in 

RHCAs for implementing this activity. There would be little disturbance to spotted frogs during 

implementation of this activity. Since workers would be walking through the area and using 

chainsaws to cut trees generally less than 9 inches dbh, frogs could move to other areas during 

this activity. 

Reconstructing roads within RHCAs (up to 3.5 miles) on Salmon, Crystal, and Rush Creeks, 

reduces sedimentation from the existing condition by improving road surfaces and drainage. 

Activities would occur when the flows of streams are low and frog eggs have hatched. 

Precipitation is low during the summer months in the project area. Frogs make use of summer 

foraging in small wet or damp areas in forest and meadows, including water-filled tracks, stream 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 97 

edges, and marshes. Frogs that use water-filled tracks from vehicles may be affected by 

reconstruction of existing roads in RHCAs. Current visitor traffic that disturbs frogs using 

water-filled tracks would no longer affect these frog sites because these sites would be destroyed. 

Road work would occur after eggs have hatched. 

Road closure work includes adding drainage structures. Long term the closed roads would have 

fewer puddles that would be used by frogs which may affect foraging frog numbers. Using small 

spur roads within RHCAs prevents building new parallel roads or opening longer segments of 

roads that would increase sedimentation to the stream and reducing vegetation. Keeping existing 

vegetation by reusing roads can be used by frogs for cover and foraging instead of building new 

parallel roads to existing roads in RHCAs. 

An estimated 124 acres of hardwood thinning would occur in RHCAs. Vegetation for summer 

and winter habitat would be improved by implementing hardwood thinning activities. Increased 

riparian vegetation would increase cover and close areas for increased humidity needed by frogs. 

Fuels treatments would occur in the spring and fall. Hand piles would be burned later in the year 

after the first snow. Egg deposition occurs for frogs soon after snowmelt. Eggs are normally 

deposited in water at temperatures of approximately 57.2 degrees F. Fire generally does not 

creep through seeps, bogs, springs, meadows, or other wet areas. Fire line would not be 

constructed in these areas. Foraging that takes place in the summer would not be affected by 

fuels treatments that take place in the spring and fall. Therefore, it is unlikely that fuel 

treatments would affect frogs or their habitat. 

These alternatives would result in a may impact individuals or habitat determination for 

Columbia spotted frog because road work within RHCAs may occur while frogs are present. 

Frogs would be expected to move to other areas. Road reconstruction would reduce the amount 

of water-filled tracks that might be used by frogs and other road work and could affect individual 

frogs. During precommercial and hardwood thinning activities, individual frogs could be 

disturbed by workers in RHCAs; frogs would be expected to move to other areas during these 

activities. 

Alternative 3 

Precommercial thinning would occur on approximately 835 acres within RHCAs. No heavy 

equipment or OHVs would be used in RHCAs for implementing this activity. There would be 

little disturbance to spotted frogs during implementation of this activity. Since workers would be 

walking through the area and using chainsaws to cut trees generally less than 9 inches dbh, frogs 

could move to other areas during this activity. 

An estimated 124 acres of hardwood thinning would occur in RHCAs. Vegetation for summer 

and winter habitat would be improved by implementing hardwood thinning activities. Increased 

riparian vegetation would increase cover and close areas for increased humidity needed by frogs. 

Fuels treatments would occur in the spring and fall. Hand piles would be burned later in the year 

after the first snow. Egg deposition occurs for frogs soon after snowmelt. Eggs are normally

deposited in water at temperatures of approximately 57.2 degrees F. Fire generally does not 

creep through seeps, bogs, springs, meadows, or other wet areas. Fire line would not be 

constructed in these areas. Foraging that takes place in the summer would not be affected by 

fuels treatments that take place in the spring and fall. Therefore, it is unlikely that fuel 

treatments would affect frogs or their habitat. 

This alternative would result in a may impact individuals or habitat determination for Columbia 

spotted frog because workers could disturb individual frogs during precommercial and hardwood 

thinning activities. Frogs are expected to move away from these areas while thinning activities 

are occurring. 

Cumulative Effects 

The cumulative effects for spotted frogs are similar to those described for RHCAs. Where the 

Hash Rock Fire burned the upper reaches of Cornez, Hamilton, McGinnis, and Reilly Creeks in 

the summer of 2000 it reduced spotted frog habitat by removing vegetation. Planting in these 

areas and natural regrowth of vegetation has increased spotted frog habitat since the Hash Rock 

fire. Large wood recruitment is now occurring as fire-killed trees fall into and near streams. 

This large wood helps to provide hiding cover for frogs. Post-fire work in the fire area has 

increased streambank stability as a result of both riparian planting and replacing undersized 

culverts on McGinnis Creek, Reilly Creek, and the east and west forks of Hamilton Creek; 

replacing two undersized culverts on Cornez Creek, and decommissioning approximately 0.4 

miles of road on McGinnis Creek. Precommercial thinning and prescribed burning along these 

streams would complement riparian planting that has already occurred, contributing to increased 

hardwood species composition and abundance. Road closure and decommission on Cornez 

Creek, Reilly Creek, and tributaries to McGinnis Creek would complement previous road 

decommission and culvert replacements along these streams. 

Activities that have occurred in the RHCAs of Jim Elliott, Little Hay, Marks, and Rush Creeks 

include road decommissioning along Jim Elliott Creek; headcut stabilization, riparian planting, 

and fencing on Little Hay Creek; riparian planting, stream channel restoration, and road 

decommissioning along Marks Creek; and riparian planting along Rush Creek. Commercial 

harvest, precommercial thinning, prescribed burning, hardwood thinning, and road work along 

these streams would also contribute toward the attainment of RMOs for pool frequency, water 

temperature, large woody debris, and width-to-depth ratios. 

Air Quality 

Affected Environment 

Air quality can be affected by both wildfire and activity fuels burning. National Ambient Air 

Quality Standards have been developed and include standards for total suspended particulates 

(solid material contained in smoke). The Oregon Department of Environmental Quality (DEQ) 

is responsible for assuring compliance with the Clean Air Act. In 1994, the Forest Service, in 

cooperation with the Oregon DEQ, the Oregon Department of Forestry, and the Bureau of Land 

Management (BLM), signed a Memorandum of Understanding (MOU) to establish a framework 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 99 

for implementing an air quality program in northeast Oregon. The MOU includes a prescribed 

fire emission limit of 15,000 tons of PM 10 per year for the national forests of the Blue 

Mountains (Malheur, Ochoco, Umatilla, and Wallowa-Whitman). PM 10 are particulate matter 

that measure 10 microns in diameter or less, and are small enough to enter the human respiratory 

system. All prescribed burning on these forests is coordinated with the Oregon DEQ and 

Department of Forestry through the State of Oregon smoke management program. 

Winds in the Spears project area are typically from the southwest-to-northwest during the spring 

and fall prescribed fire seasons. Inversions are common at night in the fall in the Marks Creek 

valley, but tend to dissipate by mid-morning. Populated areas that may be affected by smoke 

from underburning are primarily the private lands along Marks Creek. 

The nearest Class I airshed is the Strawberry Mountain Wilderness, 75 miles to the east. The 

nearest special protection sone is Bend, 50 miles to the west, into the prevailing winds. 

Environmental Consequences 

Alternative 1 

Activity fuels and natural fuels underburning activities would not occur. There would be no 

emissions produced as a result of implementing this alternative. Because Alternative 1 would 

not result in any emissions, there are no cumulative effects associated with this alternative. 

However, because the amount of fuels in the project area would not be reduced and fuels would 

continue to accumulate, the intensity of any wildfire within the project area and the amount of 

emissions it would produce would be higher than if fuels were reduced. 

Alternatives 2, 3, 4, and 5 

Direct and Indirect Effects 

Due to the location of the project area and local weather patterns, smoke from prescribed fire 

would not affect Class I airsheds or urban special protection zones. 

Burning activities would be conducted under the State of Oregon Smoke Management System to 

track smoke produced and would be coordinated with adjacent National Forests to meet smoke 

management objectives for total emissions. 

Prescribed fire operations would be conducted under favorable smoke dispersal conditions and 

would be suspended during persistent inversion conditions. Burning during inversion conditions 

increases the potential for smoke pooling in the Marks Creek valley. Residents and visitors to 

the area would encounter smoke as long as the inversion conditions persist, which can be 

anywhere from a few days to a few weeks. Residents in the area are also likely to encounter 

dust, noise, and increased traffic from prescribed burning operations. 

Underburning activities would be implemented over a period of about 10 years. The amount of 

natural fuels and activity fuels underburning would vary by alternative and the amount of 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 100 

emissions produced would vary by alternative. Table 40 displays the estimated total annual 

emissions over the 10-year implementation period for underburning activities included in each of 

the alternatives.

Alternative 2 includes the highest level of prescribed fire operations and would produce the most 

emissions. Alternative 2 would produce an estimated 2,440 tons of PM 10 particulates over the 

10-year implementation period. Alternative 4 would produce the second highest level of 

emissions and would produce an estimated 2,342 tons of PM 10 particulates. Alternatives 5 and 

3 would produce 2,240 and 1,950 tons, respectively. The highest estimated annual emission of 

PM 10 is 366 tons, which is less than 3 percent of the annual emission limit for the Blue 

Mountains. 

Prescribed fire operations would reduce the amount of fuel in the project area. With a reduction 

in fuel levels, the intensity of wildfires and the amount of emissions they produce would be 

reduced. 

Cumulative Effects 

During the summer months, there are occasional smoke intrusions into the Prineville area from 

agricultural burning in Crook and Jefferson Counties. Prescribed burning in the Spears project 

area would occur during the spring and fall, and would not coincide with those intrusions. 

In June 2006, the Ochoco Valley Fuels Reduction project was authorized. This project includes 

the use of prescribed fire on approximately 2,700 acres in the Upper Ochoco Creek Watershed 

which lies due east of the project area. This project is expected to be implemented over 2-3 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 101 

years beginning in 2007. This project is expected to produce a total of 293 tons of PM 10 

emissions over the 2-3 year implementation period. 

The Lookout Mountain Ranger District is in the process of developing the Snowshoe Fuels 

Reduction project. The purpose of the Snowshoe project is to develop a fuel break along U.S. 

Highway 26. This project is in the Bridge Creek Watershed which is adjacent to the project area 

on the north. This project is expected to include up to 200 acres of prescribed fire. The earliest 

implementation of this project would begin is fall 2007. This project is expected to produce a 

total of 22 tons of PM 10. 

Both of these fuel reduction projects will result in some smoke emissions that may overlap with 

emissions from the Spears Project. The amount of emissions from these two fuel reduction 

project would be small (less than 2% of the annual emission limit) and combined with the 

emissions from the Spears project would be less than 5% of the annual emission limit. All of 

these projects will be coordinated with the Oregon DEQ and the other National Forests in the 

Blue Mountains to ensure that the annual emission limit is not exceeded. 

Botanical Species 

Affected Environment 

There are no known proposed, endangered, or threatened plant species known or expected to 

occur on the Ochoco National Forest. Therefore, there would be no effect to threatened or 

endangered botanical species as a result of any of the alternatives. 

There are 28 plant species on the 2004 Regional Forester's Sensitive Species List documented or 

suspected to occur on the Ochoco National Forest; 13 of these species do not have potential 

habitat within the Spears project area. These species are: Estes wormwood, South Fork John 

Day milkvetch, Peck’s milkvetch, Deschutes milkvetch, long-bearded mariposa lily, dwarf 

suncup, narrow-leaved sedge, Ochoco lomatium, disappearing monkeyflower, Peck’s 

penstemon, Columbia cress, arrow-leaf thelypody, and Howell’s thelypody. There would be no 

impact to any of these species from any of the alternatives. (More information is contained in 

the January 12, 2007, botany report.) 

The 15 sensitive species that have potential habitat, or are known to occur in the project area, 

have been grouped where they occupy similar habitats, and anticipated effects of the alternatives 

are similar. The habitat groups are riparian, moist forest, and non-forest scabland. The 

following species are those that have either been documented in or near the project area, or have 

a higher potential for occurrence in the area. The groupings are as follows: 

 1. riparian species: ascending moonwort, crenulate moonwort, Mingan’s moonwort, 

mountain moonwort, twin-spike moonwort, pinnate moonwort, Peck’s mariposa lily, porcupine 

sedge, interior sedge, silverskin lichen, and margined streamside moss. 

 2. moist forest species: yellow-lady’s slipper orchid and Back’s sedge. 

 3. scabland species: Henderson’s needlegrass and Wallowa needlegrass. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 102 

Surveys were conducted for sensitive plants in the project area in 1990-1993, 2000, 2001, and 

2006. Records of these surveys can be found in the Lookout Mountain Ranger District office. 

Most of these surveys were completed as intuitive control and in areas with the highest potential 

for Peck’s lily and needlegrass species. Peck’s mariposa lily and interior sedge have been 

documented to occur in the project area. 

Riparian Species 

Moonworts (Botrychium spp.) 

The six species of sensitive moonworts known to occur on the Ochoco NF occupy similar 

riparian habitats and are discussed here as one group. This group includes ascending moonwort 

(Botrychium ascendens), crenulate moonwort (B. crenulatum), Mingan’s moonwort (B. 

minganense), mountain moonwort (B. montanum), twin-spike moonwort (B. paradoxum), and 

pinnate moonwort (B. pinnatum). Because Mingan’s moonwort has been determined to be more 

common than originally believed, it may be removed from the Regional Forester’s sensitive 

species list. The six moonwort species are considered rare and local species, meaning there are 

only a few known populations and the populations are usually small. 

These are small, primitive plants closely related to ferns. They reproduce by spores, and are 

associated with mycorrhizal fungi. Habitat for the six moonwort species is primarily moist 

ground sedge/forb communities associated with seeps, drainages, and the edges of wet meadows 

at relatively high elevations, generally over 5,000 feet. Moonwort sites are found within or 

adjacent to coniferous forest, especially grand fir (Abies grandis) communities. Though several 

surveys have been completed, none of these species have been documented in the Spears project 

area. Where these species have been found on other portions of the Ochoco National Forest, 

they occupy sites that are partially shaded to fully open at the edges of clearcuts. When found, 

more individual plants have been located at intact sites versus altered sites. At least one 

population is in a natural wet meadow. Habitat and populations appear to be stable (Ianni et al. 

1996, pers. comm. and Lesko, personal observation). Moonworts may be dependent on some 

level of natural disturbance, such as flooding or other natural processes that occasionally create 

small openings for spores to become established. 

Peck’s Mariposa Lily (Calochortus longebarbatus var. peckii) 

Peck’s mariposa lily is a local endemic, known only from the Ochoco Mountains of eastern and 

central Oregon. Most populations occur along drainages associated with Big Summit Prairie and 

Little Summit Prairie. Other populations have been recorded on McKay Creek, Marks Creek, in 

the Maury Mountains, and on the former Snow Mountain Ranger District. 

Peck’s mariposa lily occurs in vernally moist areas, along intermittent drainages and meadow 

margins. This species is a sterile triploid, reproducing asexually through the production of 

bulblets in the axil of its single leaf or flower bracts (Kagan 1996). With no genetic transfer and 

limited ability to expand into suitable habitat, maintaining existing populations is essential for 

continued species viability. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 103 

In the Spears project area, populations are primarily along meadows and low-gradient drainages 

in the lower elevations. Compared with other portions of the Ochoco National Forest, the Spears 

project area contains a moderate amount of potential habitat. The majority of plants are in the 

Grant Meadows area. Monitoring indicates populations of this species are stable (Halvorson 

2000 and 2003, pers. comm.). Proposed units with potential to affect habitat include 120, 148, 

302, 303, 407, 408, 409, 501, 502, 503, 512, 513, 514, 521, 524, 532, 538, 552, 560, 565, 734, 

742, 747, 748, 867, 888, 896, and 980. 

Non-native plants have likely contributed to a decline in Peck’s mariposa lily. Sensitive plant 

site records indicate non-native grasses such as timothy and Kentucky bluegrass are ubiquitous 

in Peck’s mariposa lily sites. These non-native grasses have been present for several decades, 

and do not appear to threaten the viability of Peck’s mariposa lily. Teasel and Canada thistle 

have begun to dominate some areas of suitable habitat for this sensitive species. Within the 

project area, it appears teasel invasion into Peck’s mariposa lily habitat has resulted in 

extirpation of one sub-population. 

Past management activities are also likely to have contributed to a decline in Peck’s mariposa 

lily. Road construction and timber harvest with heavy machinery resulted in soil disturbance that 

impacted individual plants because of their shallow root system. Soil compaction and erosion 

changed hydrological patterns and reduced potential future recruitment in some areas. Other 

activities, such as slash piling and burning, resulted in scorched soils which damaged plants and 

their habitat. Piling and burning activities also increased the risk for introduction and spread of 

non-native invasive plants that may displace Peck’s mariposa lily. 

Earlier interpretations of survey data suggest that occurrences of this species are so small in 

number, with the exception of Grant Meadows, that this species may be at risk of extirpation 

from the majority of the Marks Creek watershed. However, this species is often inconsistent in 

its flowering patterns. This can affect survey data interpretations. The 1990-1992 surveys may 

have been completed during years of relatively low flowering. Informal monitoring and field 

review since these surveys indicate populations are larger and more widespread within the 

project area (Lesko, personal observation). 

Porcupine Sedge (Carex hystericina) and Interior Sedge (Carex interior) 

These species are associated with very wet riparian habitats, usually in association with perennial 

water. On the Ochoco National Forest, porcupine sedge has been found along Black Canyon 

Creek and other creeks on the Paulina Ranger District. It also occurs in the Bridge Creek 

watershed on public lands administered by the BLM. Though surveys of potential habitat have 

been completed, this species has not been documented in the project area. It appears to be more 

often associated with non-forested lower elevations, and may not occur in the Spears project 

area. Interior sedge has been documented within the Spears project area, and in other places on 

the Ochoco National Forest. Because interior sedge is more common than had been earlier 

believed, it may be removed from the Regional Forester’s sensitive species list. Both species 

appear to be tolerant of moderate grazing disturbance (Lesko, personal observation). In Oregon, 

habitat for these species appears stable (Halvorson 2001, pers. comm., Helliwell 2001, and Yates 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 104 

2001, pers. comm.). Few areas of potential habitat in the project area presently appear to be 

threatened by non-native invasive plants. 

Silverskin Lichen (Dermatocarpon luridum) and Margined Streamside Moss (Scouleria 

marginata ) 

Silverskin lichen has been documented in a variety of aquatic habitats in Washington, Oregon, 

and California. It has been found on rocks or bedrock in streams, rivers, or seeps that are usually 

submerged or inundated for most of the year. Surveys have occurred on other portions of the 

Ochoco National Forest, and this species was documented. Because perennial streams occur in 

the project areas, habitat is assumed to be present. Habitat does not appear to be threatened by 

invasive species. Livestock use that results in physical damage by hooves may impact this 

species, but maintaining habitat for this species appears to be more related to maintaining water 

quality. 

Margined streamside moss species is endemic to the Pacific Northwest, found in southern British 

Columbia, Washington, Idaho, western Oregon, and northern California. It often forms dark 

mats on exposed to shaded rocks in streams; seasonally submerged or emergent. Surveys have 

occurred on portions of the Ochoco National Forest and this species was not found. However, 

because perennial streams occur in the project area, habitat is assumed to be present. Habitat 

does not appear to be threatened by invasive species. Livestock use may result in physical 

damage to plants by hooves. However, closely-related species appear to occupy rocky, steep 

stream habitats that are not usually associated with high livestock use. Maintaining habitat for 

this species appears to be more related to maintaining water quality. 

Moist Forest Species 

Yellow Lady's-Slipper Orchid (Cypripedium parviflorum) 

This species typically occupies very moist upland sites and riparian zones. This habitat is moist 

grand fir (Abies grandis)/twinflower (Linnaea borealis) and grand fir/beadlily (Clintonia 

uniflora) plant associations. This orchid is also known as Cypripedium calceolus var. 

parviflorum. A population of Cypripedium orchids with yellow flowers, tentatively identified as 

Cypripedium parviflorum, occurs in an old harvest unit in the Trout Creek watershed in the 

western portion of the Ochoco National Forest. This site was partially cut in the early to mid 

1970’s using an overstory removal prescription. The unit did not have any slash disposal 

following the 1970’s harvest. The population appears to be stable. It appears to be associated 

with the decomposing large woody debris left on site after the harvest and areas with partial 

shade. 

In the Spears project area, the highest-probability habitat for this species would occur on 

northerly aspects in higher-elevation western and northern portions of the area. Proposed units 

with potential to affect habitat include 163, 199, 515, 526, 542, 546, 707, 738, 748, 751, 823, 

824, 845, 846, 869, 870, 872, 889, 932, 942, 959, and 982. No populations or plants of yellow 

lady’s-slipper orchid have been documented in the project area, despite surveys for this and other 

projects, including limited-focus surveys for this species in 2000 and 2001. Other surveys in and 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 105 

near the Spears project area have documented a similar species, mountain lady’s-slipper orchid 

(Cypripedium montanum). 

While this species appears to be somewhat tolerant of moderate disturbance, heavy ground 

disturbance such as road construction or log skidding may destroy plants or habitat. Burning 

may remove large woody debris on which this species may depend. Design elements have been 

incorporated into all the action alternatives to maintain habitat for yellow lady’s-slipper orchid. 

These elements include maintaining partial shade and no slash piling or underburning on areas 

identified as yellow lady’s-slipper orchid habitat, unless reviewed by the district botanist. 

Back’s Sedge (Carex backii) 

Back’s sedge occurs across much of the western United States and Canada, though it is less 

common in the Pacific Northwest (Wood 2002). Recent information suggests occurrences of this 

species in Oregon have been misidentified, and are actually Carex cordillerana, a “new” species 

yet to be described (formally published). In central Oregon, this species was last documented in 

1916 on private land along Ochoco Creek at Cabin Station Pasture which is adjacent to the 

Ochoco National Forest. 

Back’s sedge occupies riparian areas and moist meadows, but also has been documented in moist 

woods and thickets in eastern Oregon (Wood 2003, pers. comm.). This species also occurs in 

rocky, often steep areas. These sites are less susceptible to livestock grazing, indicating this 

species may be more likely to occur in areas with little or no grazing (Lytjen 2003, pers. comm.). 

Back’s sedge is not rhizomatous and reproduces only by seed. It is not considered a fire-adapted 

species, but because it is most often found on moist sites, only high-intensity wildfire is likely to 

affect it (Wood 2002). 

Though surveys have been completed on a variety of sites throughout the Ochoco National 

Forest, including within the Spears project area, this species has not been documented on the 

Ochoco National Forest or in central Oregon. These and earlier surveys indicate this species is 

likely not present in the Spears project area. It appears likely that this species has been 

extirpated from central Oregon. The closest known populations are approximately 100 miles 

east of the project area. Populations of this species on the Umatilla, Malheur, and WallowaWhitman National Forests appear to be stable (Wood 2003, pers. comm.). It is also known to 

occur on lands managed by the Burns District of the BLM (Lytjen 2003, pers. comm.). 

Scabland Species 

Needlegrass Species (Achnatherum hendersonii and A. wallowaensis) 

These perennial grasses are regional endemic species. They are associated with residual, clay 

soils known as lithosols. This habitat is commonly referred to as non-forest balds or scablands. 

These species are uncommon but widely scattered on the Ochoco National Forest. These species 

occur sporadically in central and northeastern Oregon on rocky, scabland ridges, often in 

association with rigid sagebrush, Sandberg bluegrass, onespike oatgrass, and buckwheat species. 

Dry, heavy clay to gravelly, droughty, shallow soil is common, with aspect mostly south to 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 106 

southwest, with gentle to moderate slopes. Stone circles, stripes, and nets are common signs of 

frost heaving in these sites (Virlakas 1990 and Maze and Robson 1996). Known sites are at 

elevations of 3,400 to 5,400 feet. The closest documented populations are on land managed by 

the BLM within the North Fork Crooked River watershed. No populations of these species have 

been documented within the project area, though few areas of suitable habitat have been 

surveyed. There are two units (704 and 806) with potential to affect habitat; this includes the 

roads used to access these units. 

Studies indicate that where scabland soils occur on slopes exceeding 15 percent, measurable 

erosion has occurred over the last 100 years. As a result of these changes, productivity and plant 

community composition has also likely changed due to the loss of surface soil, grazing, and 

invasion by exotic species. Monitoring indicates the majority of this change occurred several 

decades ago. Though this species occurs on these altered sites, it is difficult to estimate effects 

of these changes on sensitive needlegrass populations. Where scablands occur on flatter slopes, 

less erosion has occurred, indicating little change in productivity and plant communities (David 

2001, pers. comm.). On the Ochoco National Forest, the majority of this habitat appears to be 

stable and is expected to remain suitable for these species. 

Monitoring of this species has not been extensive. However, scabland habitat associated with 

this species presently appears to be stable, and, except for road construction and some damage by 

OHV traffic, has changed little over the last few decades. Because scabland habitat does not 

recover from disturbance, protection is emphasized under the Ochoco National Forest Plan. 

Environmental Consequences 

Riparian Species 

Alternative 1 

This alternative includes no disturbance, such as road construction, timber harvest, burning or 

other activities that may affect viability of these species. Habitat would be maintained. 

Therefore, there would be no impact to Peck’s mariposa lily, the six moonworts, porcupine 

sedge, interior sedge, silverskin lichen, or margined streamside moss. Monitoring indicates 

populations or habitats for these species are currently stable; therefore short-term (less than 10 

years) effects are unlikely. Because Peck’s mariposa lily appears to decline if competition is not 

set back due to fire or other disturbance, the continued policy of wildfire suppression and lack of 

management practices, such as tree thinning and prescribed burning, may lead to a long-term 

decline of Peck’s mariposa lily (Kagan 1996 and Halvorson 2003, pers. comm.). 

Alternative 3 

This alternative includes no disturbance from road construction, timber harvest, or grapple 

piling. However, other activities, including thinning and hand piling and burning of slash, may 

potentially affect these species. Heavy thinning slash and piling can bury plants, and burning 

these higher fuel loads can scorch soils, damaging plants and their habitat, and increasing risk for 

introduction and spread of non-native invasive plants that may displace sensitive plants. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 107 

However, the majority of habitat would be maintained. Therefore, anticipated short-term effects 

would be that some individuals or habitat may be affected, but would not be likely to contribute 

to a trend towards federal listing or a loss of viability Peck’s mariposa lily, the six moonworts, 

porcupine sedge, interior sedge, silverskin lichen, or margined streamside moss. 

Where precommercial thinning and prescribed burning would occur along forest/meadow 

interface that contains habitat for Peck’s mariposa lily, the expected long-term effects (>10 

years) would be enhanced habitat resulting from the reduction of shade and the expansion of 

meadow habitat. This may result in expansion of populations. 

Alternatives 2, 4, and 5 

Soil disturbance from heavy machinery can directly impact individual plants. Soil compaction or 

erosion can impact future recruitment by changing hydrological patterns in riparian habitat. 

Heavy thinning slash and piling can bury plants, and burning these higher fuel loads can scorch 

soils, damaging plants and their habitat, and increasing risk for introduction and spread of nonnative invasive plants that may displace sensitive plants. 

In the long term (more than 10 years), management activities such as thinning and burning may 

improve habitat for Peck’s mariposa lily by reducing competition from conifers and other 

competing vegetation (Ianni et al. 1996, pers. comm.). 

All of the action alternatives avoid mechanical disturbance of known populations and high 

probability habitat for Peck’s mariposa lily, the six moonworts, porcupine sedge, interior sedge, 

silverskin lichen, or margined streamside moss. Ground-based equipment would be restricted in 

most Riparian Habitat Conservation Areas (RHCAs) and in areas identified as habitat for these 

species. 

Seeding of native or native cultivar grasses and forbs would take place during rehabilitation of 

log landings and portions of closed and decommissioned roads, including those in riparian areas, 

to reduce potential for erosion and introduction and spread of noxious weeds. Additional seeded 

grasses and forbs may move into Peck’s mariposa lily habitat. Observations indicate Peck’s 

mariposa lily populations and habitat are stable. Populations of native and non-native grasses 

and non-noxious forbs appear to have shared habitat with Peck’s mariposa lily for decades. 

Therefore, seeding is not expected to increase the risk to Peck’s mariposa lily. On highly 

disturbed sites such as roads, seeded grass and forbs can colonize these sites and reduce risk of 

some noxious weeds, such as teasel, which appears to be a greater threat to Peck’s mariposa lily. 

Habitat for the six moonworts, porcupine sedge, and interior sedge is very moist. Seeding 

upland grasses and forbs of the species proposed is not likely to expand into this habitat and 

affect these species. Though some localized impacts due to non-native invasive plants, such as 

teasel, are apparent in Peck’s mariposa lily habitat, they presently do not appear to threaten the 

viability of this or other sensitive species on the Ochoco National Forest. 

The riparian habitat for these species is typically excluded from timber harvest. Moist habitat is 

unlikely to burn during prescribed burning. However, other actions including road maintenance, 

reconstruction, and decommissioning, precommercial thinning, and fuels treatments that would 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 108 

occur within the RHCAs may damage some individual Peck’s mariposa lily, moonworts, 

porcupine sedge, interior sedge, silverskin lichen, and margined streamside moss plants or their 

habitats. However, these activities: (1) are expected to only affect the periphery of such habitat 

(e.g. thinning along a meadow edge); (2) are not expected to burn with high intensity; (3) would 

affect areas already heavily disturbed (e.g. road decommissioning); or (4) would occur primarily 

in marginal habitat or other areas unlikely to affect viability of populations. Therefore, 

anticipated short-term effects (less than 10 years) would be that some individuals or habitat may 

be affected, but would not be likely to contribute to a trend towards federal listing or a loss of 

viability to sensitive plant species associated with riparian areas, wet meadows, or seeps and 

springs. 

Where precommercial thinning and prescribed burning would occur along forest/meadow 

interface that contains habitat for Peck’s mariposa lily, the expected long-term effects (more than 

10 years) would be enhanced habitat resulting from the reduction of shade and the expansion of 

meadow habitat. This may result in expansion of populations. Road decommissioning may 

result in less vehicle use in riparian areas, which may also further protect, and may enhance 

habitat. 

Cumulative Effects 

Habitat quality for the majority of sensitive plant species has likely declined since historic 

conditions. Road construction, livestock grazing, fire exclusion, logging, vehicle use, stream 

channelization, introduction and spread of non-native invasive plants (noxious weeds), and other 

factors have resulted in changes to meadow and riparian habitat. 

Observations and monitoring over the last decade indicate habitats for these sensitive species are 

generally stable, despite continuing influences from livestock, noxious weeds, and recreation use 

(Lesko, pers. observation, and Halvorson 2003, pers. comm). In some areas, riparian 

improvement projects, such as planting, and headcut (stream channel) repair appear to have 

enhanced or expanded habitat for sensitive species associated with riparian areas. Where conifer 

thinning (and follow-up burning) has occurred, forest stands have moved towards conditions 

more closely approximating historic conditions. This is expected to benefit sensitive plant 

species that favor open conditions. An example is where thinning and prescribed burning 

occurred along a forest/meadow interface where fire exclusion has resulted in conifer expansion 

into meadow habitat (Arno 2000). Meadow habitat associated with Peck’s mariposa lily has 

increased, reversing the trend of shrinking meadows. 

Noxious weeds are expected to continue to be introduced by vehicles and livestock, but control

measures are occurring under the 1998 Integrated Weed Management Plan, and are expected to 

continue. The Deschutes and Ochoco National Forests are currently completing an EIS for sitespecific management of noxious weed infestations. This is expected to result in additional 

treatment areas on the Ochoco National Forest and in the Spears project area. Implementation of 

additional weed management is expected to have little short-term effect on sensitive plant 

species, and may have long-term beneficial effects. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 109 

Existing untreated infestations of non-native invasive plants are expected to spread, and threaten 

plant communities by directly displacing native vegetation, including sensitive plant species. 

Though teasel appears to have impacted at least one sensitive plant subpopulation, and Canada 

thistle also occurs in sensitive plant habitats, they currently do not appear to have a measurable 

effect on the overall viability of sensitive plant populations. Though Canada thistle is expected 

to expand, impacts to viability of sensitive plants are presently not foreseen. Spread of 

biological control agents on the Ochoco National Forest may ultimately result in a decline of 

Canada thistle. 

Assuming noxious weed control continues, weeds are less likely to affect sensitive plant habitats. 

Therefore, no cumulative effects are expected on sensitive plant species that would add to the 

direct and indirect effects described in the previous section. Noxious weeds may pose a longterm threat (>10 years), but due to variables that are hard to predict, long-term assessment of 

weed effects on sensitive plants would be speculative. 

The sensitive plant species associated with riparian areas are not expected to be affected by 

wildfire. These species occur in areas that are generally moist year-round, or in the case of 

Peck’s mariposa lily, are dormant during wildfire season. 

Monitoring indicates where livestock have been fenced out of Peck’s mariposa lily habitat, 

densities of this species appear to be decreasing, possibly due to increased competition from 

grasses (Halvorson 2003, pers. comm.). Where thinning and burning activities improve forage 

production and palatability, there may be some increased use by livestock. This improved forage 

may help to distribute livestock and its impacts over a larger area. This is not expected to result 

in cumulative effects to sensitive plant populations. 

Moist Forest Species 

Alternative 1 

This alternative does not include road construction, road decommissioning, timber harvest, 

hardwood thinning, seeding, burning, or other activities that may affect viability of these species. 

Habitat would be maintained. Therefore, no impact is expected that would likely contribute to a 

trend towards federal listing or a loss of viability to populations of yellow lady’s-slipper orchid 

or Back’s sedge. 

Alternative 3 

This alternative includes no disturbance from road construction, timber harvest, or grapple 

piling. However, other activities, including thinning and hand piling and burning of slash, may 

potentially affect these species. Heavy thinning slash can bury plants, and burning these higher 

fuel loads can scorch soils, damaging plants and their habitat, and increasing risk for introduction 

and spread of non-native invasive plants that may displace sensitive plants. However, the 

majority of habitat would be maintained. Therefore, anticipated short-term effects (less than 10 

years) would be that some individuals or habitat may be affected, but would not be likely to 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 110 

contribute to a trend towards federal listing or a loss of viability of yellow lady’s-slipper orchid 

or Back’s sedge. 

Alternatives 2, 4, and 5 

Most of the suitable habitat for these species is associated with moist grand fir habitat and upland 

portions within RHCAs. Specific measures to protect habitat were incorporated into each of 

these alternatives. 

While yellow lady’s-slipper orchid appears to be somewhat tolerant of moderate disturbance, 

heavy ground disturbance such as road construction or log skidding may destroy plants or 

habitat. Burning may remove large woody debris on which this species may depend. In yellow 

lady’s-slipper orchid these alternatives would maintain partial shade and would not pile slash or 

burn areas identified as yellow lady’s-slipper orchid habitat, unless reviewed by the district 

botanist. Additionally, harvest unit layout, activity fuels burning, and post-sale tilling in these 

areas would be reviewed by the district botanist to avoid loss of suitable habitat. 

Though surveys indicate Back’s sedge is not likely to occur in the project area, and may no 

longer occur in central Oregon, potential habitat does exist in the project area. The moist sites 

associated with this species are primarily in RHCAs. With a few exceptions, timber harvest 

within RHCAs would be completed without the use of ground-based machinery. In addition, 

large wood would be maintained in moist grand fir habitats. Weather and fuels moisture 

conditions associated with natural fuels underburning generally result in little to no fuels 

consumption in the moist forest habitats associated with these species. Therefore, this activity is 

not expected to affect viability of these species. 

Seeding of upland grasses and forbs would occur on portions of decommissioned or closed 

roads, log landings, and skid trails, including those in habitats associated with yellow lady’sslipper orchid and Back’s sedge, to stabilize soils and reduce potential for noxious weed 

introduction or spread. If available, native seed produced from local collections of pinegrass, 

blue wildrye, and bottlebrush squirreltail would be used. Otherwise, native cultivars would be 

used. They include red fescue and big bluegrass. These grasses are already present in many 

areas of the Ochoco National Forest, and primarily occur on heavily disturbed areas such as road 

shoulders and log landings. In general, they do not appear to be aggressive in displacing existing 

native vegetation (Lesko, pers. observation). Seeding these cultivars is not expected to colonize 

undisturbed areas and affect the viability of yellow lady’s-slipper orchid or Back’s sedge. Even 

less risk would be expected with the seeding of locally collected native grasses and forbs. 

Activities such as road maintenance and road decommissioning may in the short-term affect 

some habitat, but are expected to result in long-term enhancement of associated habitat by 

reducing impacts from vehicles. Aspen thinning would include removing conifers and piling 

slash that may impact habitat, but this activity is limited to less than 200 acres. Therefore, some 

individuals or habitat may be impacted by implementation of these alternatives, but is not 

expected to lead to a trend towards federal listing or affect viability of yellow lady’s-slipper 

orchid or Back’s sedge.

Cumulative Effects 

Habitat quality for the majority of sensitive plant species has likely declined since historic 

conditions. Road construction, livestock grazing, fire exclusion, logging, vehicle use, stream 

channelization, introduction and spread of non-native invasive plants (noxious weeds), and other 

factors have resulted in changes to forest habitat.

Observations and monitoring over the last decade indicate habitats for Ochoco National Forest 

sensitive species are generally stable, despite continuing influences from livestock, noxious 

weeds, and recreation use. (Lesko, pers. observation, and Halvorson 2003, pers. comm). On 

upland forest sites, prescribed burning has resulted in increased exposed soils, which have 

increased susceptibility to noxious weed introduction and spread. This risk increases when 

prescribed fire exceeds normal intensities, such as occurs during unanticipated weather changes 

during burning activity. Burning has improved forage production and palatability, and in some 

areas resulted in increased livestock use. Where areas burn too hot or where livestock grazing 

occurred before sufficient recovery of vegetation and the soil organic layer, grazing has affected 

these areas by compacting and displacing soil. This increases the risk of erosion, riparian 

degradation, and serves as vectors for introduction and spread of noxious weeds (DeClerk 1997, 

DiTomaso 1997, Arno 2000, Asher et al. 2001, and Zimmerman et al. 2002). This may affect 

long-term (>10 years) viability of sensitive plants and habitat. However, large-scale burning can 

also help distribute livestock, and its impacts, over a wider area. Grazing has occurred on what 

is now the Ochoco National Forest for a century, and a 20-year history of prescribed burning and 

successive livestock use. Sensitive plant populations presently appear stable following these 

activities (Lesko, pers. observation). 

Noxious weeds are expected to continue to be introduced by vehicles and livestock, but control 

measures are occurring under the 1998 Integrated Weed Management Plan, and are expected to 

continue. The Deschutes and Ochoco National Forests are currently completing an EIS for sitespecific management of noxious weed infestations. This is expected to result in additional 

treatment areas on the Ochoco National Forest for integrated noxious weed management. 

Implementation of additional weed management is expected to have little short-term effect on 

sensitive plant species, and may have long-term beneficial effects. 

Existing untreated infestations of non-native invasive plants are expected to spread, and threaten 

plant communities by directly displacing native vegetation, including sensitive plant species. 

Teasel and Canada thistle currently do not appear to have a measurable effect on the overall 

viability of sensitive plant populations. Though Canada thistle is expected to expand, impacts to 

viability of sensitive plants are presently not foreseen. Spread of biological control agents on the 

Ochoco National Forest may ultimately result in a decline of Canada thistle. 

Assuming noxious weed control continues, weeds are less likely to affect sensitive plant habitats. 

Therefore, no cumulative effects are expected on sensitive plant species that would add to the 

direct and indirect effects described in the previous section.

Scabland Species 

Alternative 1 

Alternative 1 avoids ground-disturbing activities on scablands that provide the primary habitat 

for both of the sensitive needlegrass species. Therefore, this alternative is expected to result in 

no impact to these species. 

Alternative 3 

Alternative 3 avoids ground-disturbing activities on scablands that provide the primary habitat 

for Henderson’s and Wallowa needlegrass. Observations indicate that scabland habitats are 

affected little, if at all, by prescribed burning activities, because these areas have very low fuel 

levels. Therefore, this alternative is expected to result in no impact to these species. 

Alternatives 2, 4, and 5 

Project design includes measures to avoid disturbance of primary habitats for sensitive plant 

species. Other actions including road maintenance, reconstruction and decommission, 

precommercial thinning, and fuels reduction activities may damage some individual Henderson’s 

and Wallowa needlegrass plants or their habitats. These activities are expected to only affect the 

periphery of such habitat (e.g. thinning along a scabland edge) or would affect areas already 

heavily disturbed (e.g. road decommissioning). Therefore, the anticipated effects would be that 

some individuals or habitat may be affected, but would not be likely to contribute to a trend 

towards federal listing or a loss of viability to sensitive plant species associated with scabland 

habitats. 

Cumulative Effects 

Habitat quality for the majority of sensitive plant species, including those mentioned above, has 

likely declined since historic conditions. Road construction, livestock grazing, fire exclusion, 

logging, vehicle use, introduction and spread of non-native invasive plants (noxious weeds), and 

other factors have resulted in changes to scabland habitat. 

Observations and monitoring over the last decade indicate habitats for Ochoco National Forest 

sensitive species are generally stable, despite continuing influences from livestock, noxious 

weeds, and recreation use (Lesko, pers. observation, and Halvorson 2003, pers. comm). 

Sensitive species associated with scablands, or non-forest balds, have changed little in the last 

few decades, and are expected to remain in their current condition. 

Species associated with scabland occur on areas with relatively low fuel levels. Because of low 

fuel levels on scablands, these sites only burn during extreme conditions, such as during high 

winds on hot summer days. This is the time when associated species are dormant, and less 

susceptible to damage by fire. These species are likely to be adapted to, and remain viable with 

periodic wildfire. Observations indicate these sites are also generally less susceptible to noxious 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 113 

weeds. Therefore, sensitive species associated with scablands are expected to be unaffected by 

wildfire or noxious weeds. 

Forest Wood Products and Jobs 

Affected Environment 

For the purposes of describing socio-economics effects on the economy, the economy was 

considered central and southeastern Oregon. The effects to the local economies are based on the 

estimated number of jobs created. 

The bulk of the area and communities potentially influenced by actions on the Ochoco National 

Forest lie within Deschutes, Crook, and Jefferson, the southern most part of Wheeler, eastern 

most part of Grant, and the northern most sections of Harney and Lake Counties (zone of 

influence or zone). The major population centers within the zone and their population figures 

based on the 2000 census are: Prineville (7,356), Bend (52,029), Redmond (13,481), Madras 

(5,078), John Day (1,821) Prairie City (1,080) and Burns/Hines (3,490) (U.S Department of 

Commerce 2001a). Populations and change for the region and by each individual county are 

displayed in Table 41.

Table 41. Central Oregon population growth.

Totals 126,216 178,089 51,873 40%

Sources: US Bureau of the Census, Vital Records, Oregon Health Division. 

Future population projections mimic that of the past decade. Deschutes, Crook, and Jefferson 

Counties are expected to continue with aggressive growth, whereas the more rural counties, 

Wheeler, Grant, Harney, and Lake are projected to grow slowly, if at all. 

According to the 2000 Census, estimated civilian labor force was: Crook, 7,525, up 12 percent 

since the 1990 census; Deschutes, 57,614, up 40 percent since the 1990 census; Jefferson, 8,570, 

up 31 percent since the 1990 census; Wheeler, 598, up 14 percent since the 1990 census; Harney, 

3,110, up 16 percent since the 1990 census; Grant, 4,051, down 4 percent since the 1990 census; 

and Lake, 3,371, down 9 percent since the 1990 census. The labor force in Oregon as a whole 

increased 18 percent. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 114 

In Crook County, the three largest sectors were trade (1,640), lumber and wood products (1,510), 

and government (1,180). Since 2000, with the closure of the remaining sawmills, employment in 

the lumber and wood products has decreased. In August 2006 there were 1,110 people employed 

in this sector. In Deschutes County the three largest sectors were Finance/Insurance/Real-estate 

(14,170), trade (13,080), and government (6,900). In Jefferson County the three largest sectors 

were government (2,460), trade (1250), and lumber and wood products (1,150). In Wheeler 

County the three largest sectors were government (200), trade (50), and finance/insurance/realestate (20). In Harney County, the three largest sectors were manufacturing (590), trade (600), 

and government (1,060). In Grant County the three largest sectors were government (1,101), 

trade (500), and finance/insurance/real-estate (430). In Lake County the three largest sectors 

were government (940), trade (500), and lumber and wood products (290) (U.S Department of 

Commerce 2001c, and Labor Trends 2006). 

Unemployment rates in the individual counties were: Crook, 9.1 percent; Deschutes, 6.4 

percent; Jefferson, 6.5 percent; Wheeler, 10 percent; Harney, 8.8 percent; Grant, 12.1 percent; 

and Lake, 10.1 percent. The unemployment rate in Oregon as a whole was 5.7 percent (U.S 

Department of Commerce 2001a). 

Since then the economies have had both better and worse years. However, in Grant, Harney, and 

Lake Counties the unemployment rate has not dipped below the 2000 unemployment rate. As of 

February 2006 unemployment rates in the individual counties were: Crook, 7.7 percent; 

Deschutes, 6.1 percent; Jefferson, 8.5 percent; Wheeler, 8.3 percent; Harney, 12.3 percent; 

Grant, 12.7 percent; and Lake, 10.7 percent. The unemployment rate in Oregon as a whole was 

6.5 percent (Labor Trends 2006) 

The economies of Deschutes and Jefferson Counties, followed by Crook, are the most robust in 

the zone. In Deschutes County, although there has been an increase in the number of jobs 

created, the huge increase in the labor force (up 40%) has negated much of this success, at least 

in terms of the unemployment rate. Crook County’s overall economic diversity which is 

dominated by one manufacturing sector industry (lumber and wood products) and one wholesale 

trade sector company (Les Schwab) is lower than the other two. However, because of the 

diversity of all three, their economies are expected to remain strong. Future projections call for 

continued growth and diversification of these economies. Even in Crook County, with the 

announcement by Les Schwab that they are going to move their corporate headquarters to Bend, 

economic expansion is expected to out pace the impact of this move. Wheeler (small agricultural 

based economy), Grant (heavy reliance on lumber and wood products and government), Harney 

(government and agriculture), and Lake (heavy reliance on lumber and wood products, 

government, and agriculture) Counties’ economies, due to their small size and lack of diversity, 

have had their economies lag substantially behind Crook, Deschutes, and Jefferson and Oregon 

as a whole. Future projections also call for continued slow growth in these three economies (U.S 

Department of Commerce 2001b, Oregon Employment Department 1992, and Yohannan 2006, 

pers. comm.). In fact Grant and Harney Counties had the highest and second highest 

unemployment rates in the state in 2005. 

Although the past decade (1990-2000) has seen a significant reduction in employment within the 

lumber and wood products industry, the lumber and wood products industry is still an important 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 115 

contributor to the local economies. In Crook County (2000), 1,510 people were employed in the 

lumber and wood products industry. This accounted for 25 percent of all wage and salary 

employment in the county, and represented the third highest paying job in the county. Since 

then, with the closure of additional sawmills, employment in the lumber and wood products has 

decreased. In August 2006 there were 1,110 people employed in this sector. Most of these jobs 

are located in the logging and secondary wood products sectors. In Deschutes County, 4,770 

people were employed in the lumber and wood products industry. This accounted for 10 percent 

of all wage and salary employment, and represented the seventh highest paying job in the county. 

In Jefferson County, 1,150 people were employed in the lumber and wood products industry. 

This accounted for 19 percent of all wage and salary employment, and represented the third 

highest paying job in the county. As of February 2006, 1,080 individuals were employed in this 

sector. In Harney County, 204 people were employed in the lumber and wood products industry. 

This accounted for 11 percent of all wage and salary employment, and represented the highest 

paying job in the county. Today, only a handful of people still work in this sector. In Grant 

County, 370 people were employed in the manufacturing sector. This accounted for 14 percent 

of all wage and salary employment (the State does not separate out the lumber and wood 

products from the other manufacturing employment), and represented the third highest paying 

job in the county. As of February 2006, 250 individuals were still employed. Of all the counties 

in the zone, Grant is the only local economy remaining with a significant dependency on logging 

and primary manufacturing (sawmills). In Lake County, 290 people were employed in the 

lumber and wood products industry, and other manufacturing. This accounted for 13 percent of 

all wage and salary employment, and represented the third highest paying job in the county. 

Today, 260 people are employed in this sector. Wheeler County has no manufacturing sector 

industries (U.S Department of Commerce 2001c and Labor Trends 2006). 

Environmental Consequences 

Timber harvest (lumber and wood products) and road work (road construction, reconstruction, 

and decommissioning) would affect employment and income in three ways: (1) direct effects 

attributable to employment associated with the harvesting, transportation, and manufacturing, (2) 

indirect effects attributable to industries that supply materials, equipment, and services to these 

activities, and (3) induced effects attributable to personal spending by the owners, employees, 

families, and related industries. Employment and personal income impacts were made from 

estimates derived from Gebert et al. (2002) and Phillips (2004 pers. comm.). The jobs associated 

with prescribed fire and precommercial thinning are based on local observations and do not 

include indirect and induced jobs. 

Table 42 shows the annual estimated job and income impacts by alternative. These estimates are 

for commercial forest products, precommercial thinning, piling of small woody debris (slash), 

road construction, road reconstruction, road decommissioning, and prescribed fire. No attempt 

has been made to value what has been termed ecosystem service values. This type of analysis, if 

done at all, is more appropriate at the Forest Plan level, not at the project level (Bartuska 2000).

Timber harvest jobs and income shown in Table 42 are based on State-wide relationships and are 

not necessarily the expected impact in any one county. Because of this, the estimated jobs and 

income figures in Table 42 are likely to be higher than what one would expect in a less 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 116 

developed rural economy. For example, the indirect and induced jobs described above would be 

less in a rural economy such as Crook’s as money “leaks” out of the local economy to Redmond, 

Bend, and the Willamette Valley. The jobs and income associated with the road work are 

directly tied to Crook County’s economy (Phillips 2005). However, they are based on all road 

work within the County. Because the road work on the Ochoco National Forest is generally less 

intensive, the number of jobs portrayed in Table 42 is likely overstated. 

Over half of the timber jobs displayed in Table 42 are associated with primary manufacturing 

(sawmills), and since there is no certainty on where this manufacturing would occur (may not be 

processed even within the zone); it is not possible to predict where many of these jobs would 

exist.

Alternative 1 

Direct and Indirect Effects 

There would not be any activities implemented; therefore, no jobs would be created. As a result 

there would be no direct benefits to the local, regional, or State economies. This alternative 

would not contribute to maintaining forest product jobs. The ability to substitute this material 

from another source is questionable given the current availability of timber, especially from 

Federal lands. As noted in the affected environment section, Crook County no longer has any 

primary manufacturing capacity and more than half of the direct jobs supported by the 

harvesting, transporting, and processing of timber are associated with primary manufacturing. It 

is unlikely that many of these local logging jobs would be supported by another harvest activity 

on the Ochoco National Forest or within the zone. This would result in some downward 

pressures on all facets of Crook County’s economy. 

The economic activity associated with road work, and vegetation and fuel treatments would not 

occur under this alternative. Except for the prescribed fire treatments (these are usually 

accomplished with local Forest resources), many of the jobs associated with these activities, 

especially the precommercial thinning and slash piling, are accomplished through the use of 

contracting and many of the resources needed, including workers, are from outside the zone. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 117 

Alternative 3 

Direct and Indirect Effects 

Alternative 3 is similar to Alternative 1 because it does not include any commercial harvest 

activities. Since most of the economic activity associated with the action alternatives is tied 

directly to commercial harvest activities, the economic effects would be similar to the No Action 

Alternative. 

Alternatives 2, 4, and 5 

Direct and Indirect Effects 

Alternatives 2, 4, and 5 propose commercial harvest activities and would contribute to the local, 

regional, and State economies. Table 42 displays the expected level of harvest in million board 

feet and the number of timber and related jobs that would be created or maintained by each 

alternative. The estimated jobs would occur over several (3-7) years as timber is harvested and 

processed. Given the major restructuring of the wood product industries over the past 10 to 15 

years, it is likely that these would not be new jobs but jobs needed to maintain current levels of 

employment in the forest products industry. As noted in the affected environment section, Crook 

County no longer has any primary manufacturing capacity. Over half of the direct jobs 

supported by the harvesting, transporting, and processing of timber are associated with the 

primary manufacturing. Although many of the logging activities may be associated with Crook 

County, the most likely location for processing is in either Grant or southern Deschutes County. 

In addition to the employment and income figures from harvesting and manufacturing of wood 

products, the vegetation, fuel treatments, and road work, would also generate jobs and income 

over the next 3 to 10 years. 

It is reasonable to expect a good proportion of the precommercial thinning work would go to 

minority-based small businesses, as they have in the past. The vast majority of these businesses 

and their employees are based along the I-5 corridor, so most of the disposable income from 

these activities would not flow into local communities. There would be some local economic 

activity generated from these activities but it may be outside the area. The primary services 

needed by the workers would be food and shelter. Local businesses that can supply food 

(grocery stores and restaurants) and other services would capture most of the money being spent 

by the workers in the area. Some businesses may increase their employment, either by 

temporarily adding employees, or giving present employees more hours. This would likely 

result in increased local household incomes during implementation of project activities. Since 

these businesses have supported similar workforces in the past, capitol expansion would 

probably not be required. 

Within the social context presented above, the action alternatives have the potential to bring in 

workers from the outside to perform logging and related activities. While the outside workforce 

is more likely to be racially diverse than the local resident population, the residents have worked 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 118 

effectively with and supported anticipated fluctuations in the workforce expected with the 

implementation of an action-based alternative. 

Cumulative Effects 

Overall, the economic influence from implementation of any of the alternatives is likely to be 

small within the economic context of the zone as a whole. Trends in employment indicate 

increased employment, primarily in construction, services, and trade. This would help 

ameliorate any adverse economic impacts under Alternatives 1 and 3. Alternatives 2, 4, and 5 

which provide commercial wood products in addition to economic activities associated with the 

other management activities, along with these same overall economic trends, will help strengthen 

local, particularly Crook’s, and regional economies. In the context of larger economies, regional 

or State-wide scales, the amount lost under Alternatives 1 and 3, or the amount provided in 

Alternatives 2, 4, and 5 would not be measurable. 

Heritage Resources and Plants of Cultural Value 

Affected Environment 

Central Oregon and the Ochoco Mountains are within the ancestral domain of several tribes 

including The Confederated Tribes of the Warm Springs Reservation, The Burns Paiute, The 

Klamath Tribes, and The Confederated Tribes of the Umatilla Indian Reservation. The Ochoco 

National Forest is within lands ceded to the government through the 1855 Treaty with the Tribes 

of Middle Oregon, or The Confederated Tribes of The Warm Springs Reservation. 

All tribes took advantage of root crops, fruits, berries, and a variety of plant life. Although the 

availability of resources fluctuated over the millennia, the archaeological record suggests the 

native inhabitants followed life ways similar to those documented through ethnographic studies 

during the late 1800’s and early 1900’s. The Northern Paiute, Wasco, Walla Walla (later called 

Warm Springs), Cayuse, Umatilla, Klamath, Modoc, and Yahooskin were present when Lewis 

and Clark arrived and each tribe has its own unique history and heritage. Archaeological sites 

today are recognized through the remaining stone tools and features. Site patterns in the Ochoco 

Mountains show a broad distribution of upland use with preferences for south facing slopes, 

major drainages, and high elevation spring sites. The environment, available resources, travel 

routes and corridors, and traditional use areas also contributed to site location preferences. 

Prior to European contact, expected site types would include lithic scatters, plant processing 

sites, habitation or residential sites, resource procurement, or quarry sites. The most common 

site type in this early time period are lithic scatter sites which include flaked stone debitage and 

flaked stone tools. 

Historic sites represent several themes including exploration, settlement, mining, trapping, 

transportation routes, livestock grazing, and ranching. Historic sites often involve wooden 

structures or cabins, carved trees, blazed trees, fence lines, trails, roads, and log watering troughs

which may be adversely affected by fire, heavy equipment, and tree falling. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 119 

Hanging black moss (Bryoria fremotii) is the most abundant culturally significant plant in the 

Spears project area. It primarily grows on the lower branches of conifers. Decades of fire 

exclusion has likely resulted in an increase of this plant. Bitterroot (Lewisia rediviva) and 

several Lomatium species occupy non-forested habitats often called scabland. Soils associated 

with scabland or lithosols are shallow with high clay content. There are small amounts of these 

roots in the Spears project area. Gathering areas are more common in the North Fork of the 

Crooked River drainage to the east of the project area. Camas (Camassia quamash), generally 

found in moist meadows, is not abundant in the Spears project area. Yampa (Perideridia 

gairdneri) generally found in forested areas is not abundant in the Spears project area. 

The project area has a variety of archaeological and historic period sites. Known sites would be 

managed to protect and retain features that make these sites eligible to the National Register of 

Historic Places (NRHP). In general, the project area is viewed as a moderate use area for early 

inhabitants. Archaeological sites tend to concentrate along the main stem of Marks Creek. 

Historic period sites are most representative of the livestock grazing theme. The historic Summit 

Trail corridor represents a travel corridor for moving livestock and a transportation route along 

the high elevation summit of the Ochoco Mountains. The route has been determined eligible to 

the NRHP and is managed to retain physical features and the natural setting along the route. 

Segments are rated by their integrity and the setting is managed through preservation, retention, 

or partial retention objectives. The corridor corresponds to existing travel routes known as Road 

27 and Road 2630. 

Environmental Consequences 

The effects analysis is based on the potential for damage to artifacts, features, environmental 

settings, and alteration of the surface and subsurface arrangement by machinery, fuel loadings, 

potential fire temperatures, and duration of fire activities. Portions of the Spears Project Area 

was surveyed during planning efforts for several small projects; then, in 1993 the entire Marks 

Creek watershed was surveyed as a whole (Maercklein 1993). During planning efforts for the 

Bandit II project, additional surveys and consultation with the Oregon State Historic Preservation 

Office was completed. During the past 10 years, no new sites have been identified. 

Direct and Indirect Effects 

Alternative 1 

Levels of natural fuels would continue to accumulate. Densely stocked understory trees would 

not be treated and thinning of larger trees would not occur. Untreated fuels under this alternative 

would increase the potential for high-intensity wildland fire. Catastrophic stand replacement fire 

may have a negative affect on physical materials, historic features, and natural setting. 

There would be no change to the natural setting along Road 27. Fuel loadings along the Summit 

Trail corridor (Road 27 and Road 2630) would continue to increase. No new roads would be 

constructed and closed roads would not be opened for use. High fuel loadings would increase 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 120 

the risk for wildfire and the subsequent fire suppression activities. Uncontrolled fire and fire 

suppression activities may lead to damage of historic features and loss of natural setting. 

The no action alternative would not modify the availability of plants of cultural value in the 

project area. 

Alternatives 2, 4, and 5 

These three action alternatives include commercial harvest activities, thinning of small trees (less 

than 9 inches dbh), and treatment of slash through piling and burning. Implementation would 

likely occur within a 10-year period. The area has been surveyed for heritage resources and 

known sites sensitive to disturbance would be avoided or qualities which make them eligible to 

the NRHP would be protected. 

Design elements were created specifically for the action alternatives in the Spears project area to 

manage cultural resources, protect heritage values, and avoid ground-disturbing activities on 

sensitive sites (see the design elements for heritage resources in Chapter 2). These design 

elements would be applied to all the action alternatives. 

Layout and marking of several units would be coordinated with the archaeologist to ensure 

cultural objectives are met. In some units, heritage sites would be avoided during unit layout and 

design. In other units, features like trails, blazes, or signs on mature trees would be retained 

within the proposed treatment unit. 

Alternatives 2, 4, and 5 propose a sequence of activities including commercial harvest, followed 

by precommercial thinning of small trees (less than 9 inches dbh), hand or grapple piling of 

slash, jackpot burning, and underburning based on stand need. The sequence of activities are 

displayed by alternative and by unit in Appendix A. These activities often include multiple 

contracts, such as one for the commercial harvest, one for thinning, and one for grapple piling. 

There is a greater risk for damage to heritage sites when multiple activities are identified under 

separate contracts, handled by a variety of specialists, and implemented over an estimated 10-

year period. 

Commercial harvest and precommercial thinning both increase the amount of surface fuels. 

Heritage sites that are sensitive to underburning and heat from burning are at risk of damage 

from the fuel reduction activities. Design elements would be applied to 20 units to reduce the 

risk of damage. Reducing stand density and removing ladder fuels through these thinning 

activities has a long-term benefit of reducing the potential for high-intensity wildfires. Grapple 

piling is also included in some units to reduce the risk by rearranging surface fuels and 

increasing the window when burning can occur. 

Grapple piling is proposed on an estimated 3,000 acres followed by pile burning. Grapple piling 

on 10 units overlaps with heritage sites where design elements would be applied to protect 

heritage values and features. Grapple piling has the potential to damage sites on the surface and 

subsurface. The grapple piles are likely to burn hotter than if the fuels were not piled, which has 

the potential to scorch the soil and alter lithic artifacts. Grapple piles along the Summit Trail 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 121 

corridor would alter the natural setting for 2-3 years until the piles are burned. Grapple piles 

would not be placed in the foreground area so that a more natural setting adjacent to Road 27 is 

retained. 

The historic Summit Trail corridor (MA-F7) is managed to retain the natural setting as well as 

physical features. This early transportation corridor includes Road 27, Road 2630, and segments 

of trails or stock driveways designated in the early 1900’s to move livestock across the forest. 

Design elements were developed with emphasis on the natural setting and foreground area 

(varies from 100 to 300 feet depending on terrain). Harvest in the foreground area would be 

minimized and low stump heights required. Skid trails, log decks, and landings would be 

restricted from the foreground area. Hand piles would be allowed and grapple piling would be 

restricted. The project identified the need for fuels reduction along Road 27 to provide for 

vehicle safety. These design elements help to ensure that the natural setting is retained along the 

Summit Trail corridor. 

Proposed treatments would reduce fuels and stand density along 1.5 miles of Road 27 Summit 

Trail corridor using a variety of methods. The activity units along the Summit Trail corridor 

include hardwood thinning (units 502, 745, 904, and 905 ); underburning (units 741, 747, and 

900); a combination of tractor harvest, precommercial thin, grapple pile, and underburn (units 

742, 748, 751, and 752); and a combination of precommercial thin, hand pile, and underburn in 

unit 743. The natural setting would be altered with the construction of one new road to access 

unit 748 (road 2700-748) and re-use of several roads (2700-655, 2700-554, and 2700-402). 

These roads would be closed when project activities have been completed. Tractor harvest 

activities would primarily treat areas adjacent to the foreground to reduce stand density and in 

some cases remove trees within the foreground area. Log decks and landings would be restricted 

from the foreground areas to retain more natural conditions adjacent to Road 27. 

Thinning of young trees and underburning would be used to reduce ladder fuels and slash in the 

foreground areas adjacent to Road 27. Stand density would be reduced and clumps of young 

trees would be left to retain a more natural setting. Thinning slash in the foreground areas would 

be lopped or hand piled. Thinning of small trees in several aspen stands (units 502, 745, 904, 

905) would emphasize aspen trees and slash would be lopped or hand piled to protect young 

aspen. 

Approximately 3 miles along Road 2630 Summit Trail corridor would be treated using 

underburning (508, 510, 514, and 555), precommercial thinning (520 and 893), and thinning in 

aspen stands (552, 909, and 407). Thinning slash would be lopped or hand piled and burned 

within 1-2 years. These activities would retain the natural setting while reducing the risk for 

wildland fire. 

The features, integrity, and natural setting of the historic Summit Trail would benefit from these 

activities in the long term (more than 10 years). Fuels would be reduced and the potential for 

high-intensity wildfires would decrease. There would be short-term (up to 10 years) effect to the 

natural setting with the increase and use of spur roads. The natural setting would be affected in 

the short-term because management activities would be visible. The casual forest visitor may 

see the removal of young trees, hand piles, scorched bark, and black or yellow needles from 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 122 

underburning in the short-term (1 to 3 years) but would not see evidence of logging or groundbased equipment. Alternatives 2, 4, and 5 would result in reducing fuels and stand density and 

maintaining the natural setting and features of the historic Summit Trail. 

The dominant culturally significant plant in the project area is hanging black moss. Proposed 

activities may reduce the density of trees that provide habitat for the hanging black moss and 

current levels would be maintained on untreated acres. Habitat and populations of the hanging 

black moss would continue to exist throughout the project area. Less than 1 percent of scabland 

habitat would be disturbed by proposed activities in the action alternatives. Populations and the 

abundance of culturally significant root crops would be expected to remain the same although 

individual plants may be affected. These species occur in open rocky areas with shallow soils. 

Such areas are sparse in the Spears project area but have been identified in rocky areas along 

Marks Creek near the Oregon Department of Transportation rock pit. 

Alternative 3 

Alternative 3 proposes prescribed fire and thinning of young trees using chainsaws. Design 

elements would be applied to protect and retain features sensitive to fire and to retain the natural 

setting along Road 27 (6 thinning units) and stock driveway segments of the historic Summit 

Trail (4 thinning units). Alternative 3 may take an estimated 10 years to complete. Heritage 

sites overlap with 26 precommercial thinning units, 14 underburn units, and 9 hardwood thinning 

units. Design elements would be applied to manage and protect the qualities which make these 

sites eligible to the NRHP. 

Alternative 3 would reduce the risk of potential stand replacement fire through understory 

thinning and underburning on 1.5 miles along Road 27 and 3 miles along Road 2630. Fuel 

loadings and stand density would be reduced. The natural setting along Road 27 would be 

retained while reducing young trees using precommercial thinning methods, lopping or hand 

piling slash, and subsequent burning of slash. There would be no new road construction or 

reconstruction on closed road systems and no use of ground based equipment. Activities along 

the Historic Summit Trail on Road 2630 would retain the natural setting, although some 

evidence of thinning and underburning activities would be evident. Alternative 3 would result in 

reducing fuels and stand density and maintaining the natural setting and features of the historic 

Summit Trail. 

Proposed activities may reduce the density of trees that provide habitat for the hanging black 

moss and current levels would be maintained on untreated acres. Habitat and populations of the 

hanging black moss would continue to exist throughout the project area. Less than 1 percent of 

scabland habitat would be disturbed by proposed activities. Populations and the abundance of 

culturally significant root crops would be expected to remain the same although individual plants 

may be affected. These species occur in open rocky areas with shallow soils. Such areas are 

sparse in the Spears project area but have been identified in rocky areas along Marks Creek near 

the Oregon Department of Transportation rock pit. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 123 

Cumulative Effects 

Ongoing activities include livestock grazing, recreation events, wildfire suppression, firewood 

cutting, mining (agate and thunder egg claims), and road maintenance. Livestock grazing in the 

Marks Creek, Wildcat, Burn, and Crystal Springs Allotments would continue. Cattle tend to 

graze and damage artifacts near water sources, spring developments, salting grounds, and along 

fences. Artifact breakage and surface disturbance is most likely to occur where cattle trail or 

concentrate. Recreation activities like camping, off road vehicle use, and unauthorized artifact 

collecting are most damaging to heritage sites. Disturbance to sites results from human use, 

vehicle use, fire rings, temporary outhouses, and vandalism. In general increased recreation use 

correlates to increased vandalism and damage to heritage sites through removal of artifacts or 

disturbance to features. Recreation use is expected to continue at the current rate and disturbance 

to sites would also continue. 

Tribal access, gathering, and collection activities would continue. 

Past projects in the vicinity of the Spears project include the Hash Rock Fire and restoration 

activities. These projects have been completed and heritage issues were addressed under a caseby-case review with the Oregon State Historic Preservation Office. There was a loss of integrity 

on a portion of the Summit Trail (Road 27) from the Hash Rock Fire and suppression activities. 

The Crystal Springs Organizational Camp permit has expired and there are no plans to renew the 

special use permit. At this time, it is likely that the structures will be removed. Any effort to 

remove these structures would be coordinated with the Oregon SHPO on a separate case-by-case 

review. 

At this time, the Forest Service is developing a proposal to modify grazing in the Burn and 

Crystal Springs Allotments. The proposal for the Burn Allotment is to change to an earlier 

grazing season. The proposal for the Crystal Springs Allotment is to change to an earlier grazing 

season with a slight reduction in AUMs (animal unit months). Proposed activities may include 

fence construction or water developments. These projects would address effects to heritage 

resources under a separate case-by-case review with the Oregon SHPO. 

The Forest Service is also developing the Snowshoe Fuels Reduction Project adjacent to the 

north boundary of the Spears project. The Snowshoe proposal is to reduce fuels by underburning 

and precommercial thinning young trees. As part of the planning efforts for the Snowshoe 

proposal, effects to heritage resource would be addressed under a separate case-by-case review 

with the Oregon SHPO. 

The Oregon Department of Transportation will continue their efforts to replace bridges on 

Highway 26 and expand the Sears Rock Pit. Both of these projects have addressed heritage 

resources under a separate case-by-case review with the Oregon SHPO. 

Relative to heritage resources and plants of cultural value, the effects of these projects and the 

Spears project area do not overlap spatially with the exception of livestock grazing. The action 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 124 

alternatives would result in more open stands and more grass and forb species which would 

increase forage availability for livestock. Livestock may use these areas, but concentrated 

livestock use in these areas is not expected. If undiscovered heritage sites exist in these areas, 

livestock use may result in some artifact breakage.

Non-native Invasive Plants (Noxious Weeds) 

Affected Environment 

Non-native invasive plants are aggressive plants capable of degrading environmental quality or 

causing economic harm. Noxious weeds are a subset of these plants and are designated 

“noxious” by the Secretary of Agriculture or state agencies. Because some non-native species 

that are known to be aggressive have not been officially designated as “noxious,” the term “nonnative invasive plants” is becoming more common. Many use the term “noxious weeds” for all 

non-native invasive plants (Sheley et al. 1999c). Both terms are used interchangeably in this 

EIS. 

Noxious weeds have many characteristics, such as rapid growth rates, high seed production, and 

extended growing periods that give them advantages over native plants (Sheley and Larson 

1994a, DeClerck 1997, Sheley et al. 1999b, and Roche and Roche 1998). 

In 2000-2003, pre-project noxious weed surveys were completed along both open and closed 

roads within the project area. The surveys focused on roads because that is where noxious weeds 

are most commonly found. Additional weed surveys occurred in 2006. Common weed species, 

such as teasel and Canada thistle, have not been completely documented, especially where 

scattered individual plants occur along road shoulders. However, along the road system, at least 

95 percent of infestations of these common weed species have been documented. 

At least 60 noxious weed infestations have been documented within the Spears project area. 

Most weeds have been present in the area for at least a decade. Noxious weed inventories 

indicate most infestations begin on disturbed areas, such as road shoulders, old log landings, and 

recreation sites. With most infestations along roads, primary introduction of noxious weeds 

appears to be through vehicles. Other vectors include water (e.g. streams), wind, livestock, 

wildlife, and mineral material and heavy equipment used for road maintenance and construction 

projects. 

Noxious weeds that are known to occur in the project area include: 

bull thistle (Cirsium vulgare) Russian knapweed (Centaurea repens) 

Canada thistle (Cirsium arvense) Scotch thistle (Onopordum acanthium) 

Dalmatian toadflax (Linaria dalmatica) spotted knapweed (Centaurea maculosa) 

diffuse knapweed (Centaurea diffusa) St. John’s wort (Hypericum perforatum) 

hound’s-tongue (Cynoglossum officinale) sulfur cinquefoil (Potentilla recta) 

leafy spurge (Euphorbia esula) teasel (Dipsacus sylvestris) 

Mediterranean sage (Salvia aethiopis) whitetop (Cardaria draba) 

medusahead (Taeniatherum caput-medusae) yellow starthistle (Centaurea solstitialis) 

morning glory (Convolvulus arvensis) 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 125 

Teasel is not listed as noxious by the State of Oregon, but is considered a non-native invasive 

plant on the Ochoco National Forest because of its potential for displacing native vegetation. 

The Ochoco National Forest is currently managing noxious weeds under the 1998 Integrated 

Weed Management Plan Decision Notice. Weed management includes a variety of strategies, 

depending on the species, size of infestation, and location. Included are chemical, cultural, 

mechanical, and biological controls. The aggressiveness of the treatment strategy varies by weed 

species. For the more aggressive species such as spotted knapweed and medusahead, the 

threshold for control is one plant. Monitoring of treated infestations has shown that weed control 

has been effective, and herbicide use has declined where treatment has occurred. However, 

noxious weeds are continuing to spread and new infestations are being discovered. The 

continued spread of noxious weeds is likely. 

For species such as knapweed, controls are being implemented, and density of weeds is 

decreasing, though on the majority of sites, some seed production still occurs from plants that 

germinate after treatment, re-sprout after incomplete pulling, or otherwise escape the control. As 

long as seed production continues, eradication is difficult. This situation is complicated by the 

persistence of viable seed in the soil for many years (Eddleman 1996, pers. comm.). 

Canada thistle may be the most common noxious weed on the Ochoco National Forest. It can be 

found on a variety of sites, including rock pits, roadsides, dispersed camping areas, meadows, 

and old harvest units. In susceptible areas, numerous, small infestations of this plant are often 

followed by rapid expansion (Sheley 2004). This perennial plant has a deep root system which 

makes hand pulling infeasible. Because Canada thistle is so common, management has focused 

on biological controls; some biological controls have become established in some areas of the 

Ochoco National Forest. Ongoing research and monitoring has shown some success in reducing 

weed densities in central Oregon. Within the Spears project area, the effectiveness of biological 

controls has been limited and Canada thistle infestations continue to expand. 

Common, widespread species, such as bull thistle, Canada thistle, and teasel have not all been 

documented, and are not receiving herbicide or mechanical treatments. Though bull thistle 

quickly establishes the first few years following burning or timber harvest, its density decreases 

over time as other vegetation becomes re-established. Teasel is common, especially in riparian 

areas along U.S. Highway 26. 

New infestations of a variety of species have been documented within the project area over the 

last several years. These new infestations were not included in the 1998 integrated weed 

management decision. Currently, treatment of these infestations is limited to hand pulling. 

Individual noxious weed plants are occasionally found by field-going personnel; many of these 

weeds are hand pulled and removed when encountered.

The Deschutes and Ochoco National Forests are in the process of completing an EIS that 

analyzes a proposal for site-specific treatment of specific noxious weed infestations. This 

planning effort will expand noxious weed treatments. The EIS includes a proposal to use new 

herbicides and methods. Noxious weed management on the Ochoco National Forest will be 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 126 

modified and will depend on the upcoming decision that results from the Deschutes and Ochoco 

National Forest Invasive Plant Treatment EIS. The upcoming decision is expected to increase 

weed treatments in the Spears project area. 

The degree of environmental impact due to noxious weeds is relative to weed density. Although 

more than 60 infestations occur within the project area, infestations are generally limited to road 

corridors. Due to ongoing weed management, these infestations are typically small, less than 

1/10 acre, and collectively they occupy less than 1 percent of the project area. At this time, 

environmental effects related to noxious weeds is low. With current control measures, weed 

densities are not expected to increase substantially in the next 10 years. 

Environmental Consequences 

The Forest Service is required to determine factors that would increase the risk for introduction 

and spread of noxious weeds, and design projects to reduce these risks, especially for ground 

disturbing and site altering activities (FSM 2081). Proposed commercial harvest activities would 

remove vegetation and disturb the soil organic layer, increasing potential for introduction and 

spread of noxious weeds. Though prescribed burning is normally low intensity, burning slash 

piles or intense burning that results in scorched soils can increase risk by increasing the time 

needed for vegetation to re-establish. Chapter 2 includes design elements that are incorporated 

into all the action alternatives to reduce the risk of introducing and spreading noxious weeds. 

Direct and Indirect Effects 

Alternative 1 

Alternative 1 does not create any additional ground disturbance. Alternative 1 does not include 

any road construction, timber harvest, slash piling, or burning that would result in exposed soils. 

This alternative would have no potential for increasing the risk for introduction and spread of 

noxious weeds. The present level of risk would continue from existing infestations. New weed 

infestations are likely to become established within the project area as a result of ongoing 

activities, such as vehicle use by the public and livestock grazing. Compared with the other 

alternatives, Alternative 1 offers the lowest risk for introduction and spread of noxious weeds. 

Alternatives 2, 4, and 5 

Alternatives 2, 4, and 5 would create additional ground disturbance and exposed soils from road 

construction, timber harvest, grapple and hand piling of slash, and underburning. Alternative 2 

would create an estimated 4,994 acres of ground disturbance, the highest amount among the 

action alternatives. Alternative 4 would create 4,577 acres, and Alternative 5 would result in an 

estimated 4,157 acres of new ground disturbance. 

Though risk would increase due to additional ground disturbance, these alternatives also include 

prevention measures, such as minimizing exposed soils and requiring “certified clean” 

equipment. Measures to reduce these risks have been incorporated in all action alternatives, 

either as project design elements, such as requiring clean equipment, or site-specific, such as the 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 127 

omission of commercial harvest from Units 501 and 503. Following project activities, road 

closures and seeding would reduce risk of weed introduction and spread. Increased risk from 

ground disturbance would be partially offset by reduced vehicle use. Post-project weed 

monitoring would occur and is expected to detect infestations while they are relatively small. 

Alternatives 5, and then 4 have progressively higher risk, with Alternative 2 creating the most 

exposed soils and having the highest risk of introducing and spreading noxious weeds. 

Alternatives 3 

Alternative 3 does not include any ground disturbance resulting from road construction or timber 

harvest. However, hand piling of slash and underburning would result in exposed soils and 

increase the risk for introduction and spread of noxious weeds. Hand piling and burning of slash 

would create an estimated 2,956 acres of exposed soils. Alternative 3 has the least amount of 

increased risk when compared to the other action alternatives. 

Cumulative Effects 

The exact source of non-native invasive plant infestations is unknown, but they are expected to 

have originated from several areas. The location pattern shows concentrated sites along roads. 

Other infestations are associated with recreation sites and mineral material sites, indicating the 

primary vector for noxious weeds appears to be vehicles. Vehicle use and other activities will 

continue in the Spears project area, regardless of the alternative chosen, including no action. 

Additional introduction and spread of noxious weeds, especially hound’s-tongue, appears to be 

through livestock and wildlife (Lesko, pers. observation, and DeClerck 1997). Some infestation 

in the project area have been documented on sites that have had relatively little disturbance. 

There is an inherent risk of new infestations (such as from windblown seed) in all alternatives, 

regardless of other activities. 

The cumulative effects of present and reasonably foreseeable activities indicate a high risk for 

introduction and spread of noxious weeds. Weeds will continue to be introduced and spread by 

vehicles, livestock, fence maintenance, the recreating public (horseback riders, hikers, and 

campers), water, windborne seed, wildlife, and other sources. 

Prevention techniques for weed risk associated with reasonably foreseeable activities, such as 

requiring clean equipment for road maintenance are expected to be effective in reducing weed 

risk. The majority of other activities, including legal recreational driving and illegal off-road 

vehicle use, are more difficult to control. Wet season illegal off-road use and legal road use can 

be conducive to weed spread because mud can contain weed seeds and can cling to tires. The 

current weed treatment activities are reducing the cumulative effects related to weed risk. 

Wildfire and fire suppression can result in introduction or spread of weeds by equipment brought 

in from different areas that may contain weed seed or plant parts. Because of the emergency 

nature of wildfire, prevention measures including equipment cleaning are not always 

implemented or feasible. Dozer lines, hand lines, drop points, safety zones, and staging areas, all 

result in exposed soils which increase the risk of spread of noxious weeds. These sites are all 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 128 

heavily traveled which again increases the risk of introducing and spreading noxious weeds. 

Vehicle traffic during and after suppression activities can introduce weeds to highly susceptible 

soils. Therefore, introduction and spread from wildfire suppression activities is possible. Use of 

natural fire control lines, such as rocky ridges and existing roads, can reduce the risk of weed 

spread. Fire rehabilitation efforts are normally implemented that can mitigate many of the 

effects of the suppression activities. 

Human use of the National Forest is increasing and is expected to continue to increase in the 

future as populations in nearby towns continue to grow. Increased human use and expanding 

non-native noxious weed infestations outside the Spears project area will likely increase the 

potential for new noxious plant infestations. 

Where controls have been implemented, weed infestations have generally decreased. 

Management of weed infestations included in the 1998 Integrated Weed Management Plan is 

expected to continue until a new management plan is adopted. The remaining untreated 

infestations would continue to spread, displacing native and desirable non-native vegetation and 

reducing biodiversity. 

The Deschutes and Ochoco National Forests are currently completing an EIS for integrated 

noxious weed management. Integrated weed management on the Ochoco National Forest will be 

modified based on upcoming decisions resulting from this EIS process. A decision on this EIS is 

expected to occur in 2007. 

The degree of environmental impact due to noxious weeds is relative to the acres infested. 

Collectively, noxious weeds occupy less than 1 percent of the project area. Therefore, at present, 

environmental effects due to noxious weeds is considered low. Assuming noxious weed control 

continues, anticipated effects resulting from introduction and spread of noxious weeds is 

expected to remain relatively low. 

Recreation 

Recreation use in the project area includes wildlife viewing, hunting, fishing, driving for 

pleasure, camping, hiking, mountain biking, rock hounding, geo-caching, off-highway vehicle 

driving, horseback riding, cross-country skiing, snowshoeing, sledding, dog sledding, and 

snowmobiling. The project area includes a small portion of the Mill Creek Wilderness. 

There are several developed recreation sites within the project area: Ochoco Divide 

Campground, White Rock Campground, White Fir Springs, Bandit Springs Recreation Area, 

Ochoco Divide Snow Park, and Marks Creek Snow Park. There are also numerous dispersed 

campsites, such as the Corral Flat area. 

This section has been divided into five topics including Bandit Springs Recreation Area, 

Developed and Dispersed Camping Areas, Snow Parks, Trails, and Wilderness. Changes to the 

visual character of the scenery are described in the Visual Quality section later in this chapter. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 129 

Bandit Springs Recreation Area 

Affected Environment 

The Bandit Springs Recreation Area consists of 1,580 acres and is located near Ochoco Divide 

between the Mill Creek Wilderness and U.S. Highway 26. The area is a popular cross-country 

ski area and contains approximately 14 miles of designated ski trails. The Forest Plan emphasis 

for the area is to provide a variety of dispersed, non-motorized recreational opportunities within 

a setting where most management activities are generally not evident to the casual observer. 

Forest Plan direction specifies that periodic manipulation of the vegetation, including timber 

harvest, will occur to develop and maintain resistance to catastrophic events which would detract 

from the recreational experience. Management activities would be apparent in the area. 

Many of the forest stands in the area feature large diameter ponderosa pine with developing 

understories of fir, pine, and larch. The Forest Plan notes that ponderosa pine areas should be 

managed for a combination of multi-storied stands and open, park-like stands. Mixed conifer 

areas should be managed to maintain a mix of species with an emphasis on maintaining western 

larch. 

Approximately 975 acres of the Bandit Springs Recreation Area and 6.2 miles of trail in the 

recreation area were burned in the Hash Rock Fire. Intensities varied from high-intensity stand 

replacement fire to low-intensity underburning. Most of the high-intensity fire occurred adjacent 

to and south of McGinnis Creek. 

Environmental Consequences 

Alternative 1 

This alternative does not include any vegetative treatments. The recreational experience would 

not be directly affected by harvest or non-harvest activities. Understories would continue to 

develop and increase the amount of multi-storied conditions. The amount of open, park-like 

stands of ponderosa pine would continue to decrease. Stand densities would continue to increase 

placing additional stress on older overstory trees. Shade-tolerant grand fir would continue to 

become more abundant, while ponderosa pine and larch dominance would decrease. Fuel 

loadings, including small understory trees, would continue to increase. Susceptibility to wildfire 

and/or insects and disease would continue increasing over time. Dense, multi-storied stands are 

susceptible to disturbance and, as these conditions increase over time, additional high-intensity 

wildfires would be expected to occur. In the long term, scenic quality would be degraded as 

open stands of large diameter ponderosa pine become less abundant. Riparian and upland 

vegetation along McGinnis Creek would recover from the Hash Rock Fire. Riparian vegetation 

would recover unaided by aspen improvement projects.

Alternative 2 

Within the Bandit Springs Recreation Area, this alternative includes 327 acres of commercial 

harvest and 278 acres of precommercial thinning designed to develop or maintain resilience to 

natural disturbance events. (The prescriptions for commercial activities also include 

precommercial thinning and activity fuels underburning; the prescriptions for precommercial 

thinning also include activity fuels underburning). Forest stands would move toward conditions 

that are more sustainable and resistant to high-intensity wildfire or large-scale insect and disease 

outbreaks. Commercial harvest and precommercial thinning activities would focus on removing 

small tress from the understory. Large trees would be retained. Stand densities would be 

decreased, single-storied open conditions would become more abundant, and fire-tolerant 

ponderosa pine and larch would be maintained. Competitive stress within stands would be 

reduced which would increase growth rates and encourage the development of more large trees 

over time. More of the older, larger diameter trees would be maintained over time. Stand 

resiliency would be increased and the likelihood of disturbances, like the Hash Rock Fire, would 

be reduced. A variety of stand conditions, including both ponderosa pine and mixed conifer, 

would be retained in the Bandit Springs Recreation Area. 

Natural fuels underburning (39 acres) would be used to maintain or reduce fuel loadings and 

reduce the abundance of small understory trees. Reducing or maintaining low fuel loadings 

would increase the resistance to catastrophic wildfire events. This was demonstrated during the 

Hash Rock Fire when the fire essentially stopped at the boundary of the 1995 Mill Creek 

Prescribed Natural Fire (PNF). The Mill Creek PNF effectively reduced the intensity and rate of 

spread of the Hash Rock Fire (Owens 2001). Table 43 displays the acres of activities within the 

Bandit Springs Recreation Area for all alternatives. 

Commercial harvest, precommercial thinning, and underburning activities would create short 

term (3-5 years) and long term (10-15 years) effects that would be evident to the casual visitor. 

Such effects include impacts to visual quality, recreational experiences, and trails. In the short 

term (up to 10 years), the visual quality may be affected as visitors would see stumps, slash piles 

(grapple and hand piles), bare soil, skid trails, smoke, and boundary tags. There would be 

decreased stand densities and fewer small trees which would open up the views of surrounding 

areas and natural features. In the long term (more than 10 years), the visual quality would be 

enhanced as more large ponderosa pines develop and views of open, park-like stands become 

more frequent. 

Summer users may encounter noise, dust, smoke and logging-related traffic if they are present 

when these activities occur. As a result, the natural recreation experience may be altered due to 

short term disturbance of solitude and primitiveness. Precommercial thinning would leave small 

diameter (9 inches dbh) trees on the ground after they have been cut. Thus, traveling off of trails 

and roads would be more difficult for 3-8 years until slash from logging and precommercial 

thinning is burned. Mountain bikers would have a difficult time if riding off trails and roads, but 

hikers and horseback riders would still be able to step over the small trees. Users may be 

temporarily displaced during harvest activity due to area closures for safety reasons. Cross-
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 131 

country skiers and other winter users would not be displaced or disturbed because commercial 

timber harvest activities would be restricted between Thanksgiving and March 30. 

Some of the cross-country ski trails are on existing roads which would be reopened during 

harvest activities. The trails may appear wider because they would be cleared and used for 

logging traffic. There would be approximately 2.4 miles of road work within the Bandit Springs 

Recreation Area. This includes approximately 0.3 mile of new road construction and closing the 

roads after timber hauling and 0.2 mile of new road construction and decommissioning the roads 

after timber hauling. 0.2 mile of existing roads would be decommissioned and 1 mile of existing 

roads would be closed following timber haul. Visuals may be affected as road beds would be 

evident in the long run but would eventually become overgrown with vegetation. 

Decommissioned roads would be torn up, seeded, and water barred after use. These roadbeds 

may provide cross-country skiers more trail opportunities. 

Out of the 14 miles of designated ski trails within Bandit Springs Recreation Area, 7.1 miles are 

either within or adjacent to units. Bike Tie Trail is not in any units. 0.7 miles of Easy Trail, 0.4

miles of McGinnis Creek Trail, and 0.2 miles of Woodpecker Trail are in or adjacent to 

precommercial units. 0.1 miles of McGinnis Creek Trail, 1.4 miles of Ponderosa Loop Trail, and 

0.4 miles of Ochoco Way Trail are in or adjacent to underburn units. 1.9 miles of McGinnis 

Creek Trail, 0.1 miles of Ponderosa Loop Trail, 0.2 miles of Ridge Climb Trail, 0.7 miles of 

Woodpecker Trail, and 0.7 miles of Ochoco Way Trail are in or adjacent to commercial harvest 

units. Table 44 displays a summary of miles of trail within units for all alternatives. 

Design elements (see Chapter 2) have been incorporated to reduce impacts to recreational users. 

These include timing of activities to avoid the high-use winter season, minimizing stump heights 

so stumps are less visible, placing boundary tags and marking paint on the back side of trees or 

removing them after treatment to reduce the visibility, and clearing ski trails of slash prior to the 

winter season. 

Alternative 3 

This alternative includes 536 acres of precommercial thinning and activity fuels underburning 

designed with similar objectives as described for Alternative 2. Activities would focus in stands 

which have abundant numbers of small (less than 9 inches dbh) trees. Small tree densities would 

be decreased, single-storied open conditions would become more abundant, and fire-tolerant 

ponderosa pine and larch would be maintained. Stand resiliency would be increased where 

treatment occurs and the likelihood of disturbances like the Hash Rock Fire would be reduced, 

although not to the same extent as Alternatives 2, 4, and 5. Precommercial thinning alone would 

not remove enough competitive stress to achieve objectives for increasing the amount of late and 

old structure. 

Natural fuels underburning (39 acres) would occur as discussed in Alternative 2 to maintain or 

reduce fuel loadings and reduce the abundance of small understory trees. Reducing or 

maintaining low fuel loadings would increase the resistance to catastrophic wildfire events. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 132 

Precommercial thinning and fuels activities would create short term (3-5 years) and long term 

(10-15 years) effects that would be evident to the casual visitor. Such effects include impacts to 

visual quality, recreational experiences, and trails. In the short term, the visual quality may be 

affected as visitors would see stumps, hand piles, bare soil, smoke, and boundary tags. The 

exposed stumps would be smaller and, therefore, would deteriorate faster. There would be 

decreased stand densities and fewer small trees which would open up the views of surrounding 

areas and natural features. There would be reduced screening along the trails due to the decrease 

in small diameter trees. In the long term, the visual quality would be enhanced as more large 

ponderosa pines develop and views of open, park-like stands become more frequent. 

This alternative includes using existing roads and no new roads would be constructed. As a 

result, the natural recreation experience may be better retained than Alternatives 2, 4, and 5. The 

scatter/lop fuel treatment would leave more small trees scattered on the ground. Traveling off of 

trails and roads would be more difficult for 3-8 years until slash from precommercial thinning is 

burned. Thus, mountain bikers would have a difficult time if riding off trails and roads, but 

hikers and horseback riders would still be able to step over the small trees. The activity area 

would not be closed and summer users would not be temporarily displaced. There would be no 

conflicts between recreation users and logging traffic. 

Out of the 14 miles of designated ski trails within Bandit Springs Recreation Area, 7.1 miles are 

either within or adjacent to units. Bike Tie Trail is not in any units. 0.7 miles of Easy Trail, 2.3

miles of McGinnis Creek Trail, 0.1 miles of Ponderosa Loop Trail, 0.2 miles of Ridge Climb 

Trail, 0.7 miles of Woodpecker Trail, and 0.7 miles of Ochoco Way Trail are in or adjacent to 

precommercial units. 0.1 miles of McGinnis Creek Trail, 1.4 miles of Ponderosa Loop Trail, 0.2 

miles of Woodpecker Trail, and 0.4 miles of Ochoco Way Trail are in or adjacent to underburn 

units. 

Alternative 4 

This alternative includes 327 acres of commercial harvest and 278 acres of precommercial 

thinning. Precommercial thinning would focus on stands which have abundant numbers of small 

(less than 9 inch dbh) trees. Small tree densities would be decreased, single-storied open 

conditions would become more abundant, and fire-tolerant ponderosa pine and larch would be 

maintained. Stand resiliency would be increased where treatment occurs and the likelihood of 

disturbances like the Hash Rock Fire would be reduced. 

Natural fuels underburning (113 acres) would occur as discussed in Alternative 2 to maintain or 

reduce fuel loadings and reduce the abundance of small understory trees. Reducing or 

maintaining low fuel loadings would increase the resistance to catastrophic wildfire events. 

Commercial harvest, precommercial thinning, and underburning activities would create short 

term (3-5 years) and long term (10-15 years) effects that would be evident to the casual visitor. 

Such effects include impacts to visual quality, recreational experiences, and trails. In the short 

term, the visual quality may be affected as visitors would see exposed stumps, slash piles 

(grapple and hand piles), bare soil, skid trails, smoke, and boundary tags. There would be 

decreased stand densities and fewer small trees which would open up the views of surrounding

areas and natural features. In the long term, the visual quality would be enhanced as more large 

ponderosa pines develop and views of open, park-like stands become more frequent. 

This alternative focused on using existing roads. There would be approximately 2.1 miles of 

road work within the Bandit Springs Recreation Area. This includes approximately 0.2 mile of 

new road construction and decommissioning the road after timber hauling. 0.2 mile of existing 

road would be decommissioned and 1 mile of existing road would be closed following timber 

haul. Visuals may be affected as road beds would be evident in the long run but would 

eventually become overgrown with vegetation. Decommissioned roads may be torn up and 

water barred after use. The roads may provide cross-country skiers more trail opportunities. 

Summer users may encounter noise, dust, smoke and logging-related traffic if they are present 

during these activities. The natural recreation experience may be altered due to short term 

disturbance of solitude and primitiveness. Precommercial thinning would leave small diameter 

(9 inches dbh) trees on the ground after they have been cut. Thus, mountain bikers would have a 

difficult time if riding cross-country. Hikers and horseback riders would be able to step over the 

small trees. Summer users may be temporarily displaced during harvest activity due to area 

closures for safety reasons. Cross-country skiers and other winter users would not be displaced 

or disturbed because commercial timber harvest activities would be restricted between 

Thanksgiving and March 30. 

Out of the 14 miles of designated ski trails within Bandit Springs Recreation Area, 8.2 miles are 

either within or adjacent to units. 0.7 miles of Easy Trail, 0.4 miles of McGinnis Creek Trail, 

and 0.2 miles of Woodpecker Trail are in or adjacent to precommercial units. 0.5 miles of Bike 

Tie Trail, 0.2 miles of Easy Trail, 0.2 miles of McGinnis Creek Trail, 1.4 miles of Ponderosa

are in or adjacent to commercial harvest units. 

Alternative 5 

This alternative includes 197 acres of commercial harvest and 315 acres of precommercial 

thinning. Precommercial thinning would focus on stands which have abundant numbers of small 

(less than 9 inch dbh) trees. Small tree densities would be decreased, single-storied open 

conditions would become more abundant, and fire-tolerant ponderosa pine and larch would be 

maintained. Stand resiliency would be increased where treatment occurs and the likelihood of 

disturbances like the Hash Rock Fire would be reduced, although not to the same extent as 

Alternative 2. 

Natural fuels underburning (115 acres) would occur as discussed in Alternative 2 to maintain or 

reduce fuel loadings and reduce the abundance of small understory trees. Reducing or 

maintaining low fuel loadings would increase the resistance to catastrophic wildfire events. 

Commercial harvest, precommercial, and fuels activities would create short term (3-5 years) and 

long term (10-15 years) effects that would be evident to the casual visitor. Such effects include 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 134 

impacts to visual quality, recreational experiences, and trails. In the short term, the visual quality 

may be affected as visitors would see exposed stumps, slash piles, bare soil, skid trails, smoke, 

and boundary tags. There would be decreased stand densities and fewer small trees which would 

open up the views of surrounding areas and natural features. The prescriptions in this alternative 

include variable density thinning, leaving clumpier stand structures, and leaving higher densities 

in moist areas. In the long term, the visual quality would be enhanced as more large ponderosa 

pines develop and views of open, park-like stands become more frequent. 

Summer users may encounter noise, dust, smoke and logging-related traffic if they are present 

when these activities occur. As a result, the natural recreation experience may be altered due to 

short term disturbance of solitude and primitiveness. Precommercial thinning would leave small 

diameter (9 inches dbh) trees on the ground after they have been cut. Thus, mountain bikers 

would have a difficult time if riding cross-country. Hikers and horseback riders would be able to

activities due to area closures for safety reasons. Cross-country skiers and other winter users 

would not be displaced or disturbed because commercial timber harvest activities would be 

restricted between Thanksgiving and March 30. 

Some of the trails are on existing roads which would be reopened during harvest activities. The 

trails may appear wider due to clearing and use during harvest activities. There would be 

approximately 1.7 miles of road work within the Bandit Springs Recreation Area. This includes 

approximately 0.3 mile of new road construction and closing the road after timber hauling and 

0.2 mile of new road construction and decommissioning the road after timber hauling. 0.1 mile 

of existing road would be decommissioned and 0.4 mile of existing road would be closed 

following timber haul. Visuals may be affected as road beds would be evident in the long run

Cumulative Effects 

In 2005, the Forest Service published a new rule for providing motor vehicle access to the 

national forests and grasslands. When implemented, the rule prohibits use of motor vehicles 

outside or off designated roads, trails, and areas. Some trails, roads, and areas will be closed in 

the future and others will be designated for motorized travel. The implementation date is 

expected to be in 2009. The Ochoco National Forest is in the preliminary process of developing 

a proposed action. This effort is not expected to alter recreational use in the Bandit Springs 

Recreation Area because the emphasis for this area is non-motorized recreational opportunities. 

There are no other planned or reasonable foreseeable activities that are expected to alter 

recreational use in the Bandit Springs Recreation Area. 

Developed and Dispersed Camping Areas 

Affected Environment 

Developed recreation areas include sites that are currently developed for camping, trailhead 

parking, and other recreational activities. The campgrounds within the project area include 

Ochoco Divide and White Rock Campgrounds. Dispersed recreation areas include user-created 

sites generally along roads and riparian areas, such as White Fir Springs and Corral Flat. Within 

the project area boundary, there are approximately 52 Forest Plan identified dispersed sites. 

Ochoco Divide Campground is a popular, heavily used site within a mature stand of 

predominantly ponderosa pine just off U.S. Highway 26. It is located 30 miles northeast of 

Prineville at the summit of Ochoco Pass. This concessionaire-operated campground provides 28 

campsites with potable water and garbage service. The primary use season is May 1 through 

September 15. Most visitors arrive late in the evening and continue on their trip in the morning, 

so the area is generally quiet and vacant during the day. 

White Rock Campground is a primitive camp within a stand of mostly grand fir. It is located at 

the eastern boundary of Mill Creek Wilderness, approximately 31 miles east of Prineville at the 

end of Forest Road 3350-300. There are two campsites with tables, fire rings, and a toilet. This 

campground also serves as the trailhead for the Wildcat Trail. Most use at this site is by people 

accessing the Wildcat Trail. The primary season of use is from late May through early 

November. Hunters usually occupy this area during the latter months of the use season. There is 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 136 

also a popular rockhounding area near this campground. Fire line construction during the Hash 

Rock Fire increased potential rockhounding activities in the area. Ground-disturbing activities 

generally bring thundereggs and agates closer to the surface. 

White Fir Springs is a primitive site used primarily by rockhounders during early spring and 

summer and by hunters during late fall. This site is located off Forest Road 3350. There are two 

popular rockhounding sites near this camp. 

Corral Flat is a dispersed camping site that is primarily used by equestrian enthusiasts. Annual 

Special Use Permit (SUP) events, such as Endurance Rides, are staged at this area. The 

Prineville Ridge Riders have a 5-year endurance ride SUP that authorizes use of non-system 

trails that connect to the camping area. The trails consist of a 12, 20, and 30-mile loop. On 

average, 90 riders participate in this ride. This dispersed site is located approximately 27 miles 

east of Prineville off Forest Road 2630. The open meadows and large ponderosa pine stands 

draw visitors to the area. There are no units near or adjacent to the Corral Flat dispersed camp 

site. Campers at this area would not be affected. 

Environmental Consequences 

Alternative 1 

There would be no direct effect on camping sites within the project area. Use of these sites is not 

expected to change. Over time, the visual character of the areas would change as understory 

trees grow and stands become denser. Large diameter ponderosa pine trees would become less 

common. 

Alternative 2 

Treatments would improve the long-term health of timber stands adjacent to the above camping 

areas (developed and dispersed sites), thus creating a more appealing natural setting. Visitors 

would be able to see the ‘before and after’ effects of vegetation treatments if they visit the sites 

frequently. Commercial harvest, precommercial thinning, and fuels activities would create short 

term (3-5 years) and long term (10-15 years) effects that would be evident to the casual visitor. 

Short-term impacts would be evident near some of the camping areas. Effects from commercial 

harvest activities would include increased noise and dust from logging operations, increased 

traffic from timber hauling, reduced visual quality due to logging slash, stumps, exposed dirt, 

smoke, and blackened ground and vegetation from underburning activities. In the long term, the 

visual quality would be enhanced as more large ponderosa pines develop and views of open, 

park-like stands become more frequent. 

There are no units adjacent to Ochoco Divide Campground, but underburning (approximately 88 

acres total) within one-quarter of a mile of the campground would occur. Smoke would be 

present during burning. Visitors would not be displaced, but may encounter smoke. There are 

no units adjacent to White Rock Campground, but within one-quarter of a mile, units 

(approximately 36 acres total) would be commercially harvested and impacts from logging 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 137 

activities would be apparent to visitors. Table 45 displays the acres of treatment within 0.25 

miles of campgrounds for all alternatives. 

Ground disturbance associated with tractor logging systems and road construction activities may 

increase the potential for rockhounding because agates and thundereggs would be more exposed. 

The amount of rockhounding activities near White Rock Campground and White Fir Springs 

may increase. 

Vegetation treatments would be evident in and around dispersed campsites. Some users may be 

temporarily displaced due to loss of access during harvest activities. This may increase camping 

at other dispersed sites. See Table 46 for number of dispersed sites within treatment units for all 

alternatives. 

Alternative 3 

Precommercial thinning and underburning activities would have short-term impacts on users, 

such as noise from thinning activities and smoke during underburning. Blackened ground and 

vegetation, and slash and small stumps would be visible. Visual evidence of activities may be 

apparent to the casual forest visitor at or near some camping areas. Over time, large ponderosa 

pine trees would be more apparent. This alternative has no commercial harvest or road building. 

There are no units directly adjacent to Ochoco Divide Campground, but within one-quarter of a 

mile, units (approximately 24 acres total) would be precommercial thinned, and approximately 

40 acres would be underburned. Smoke would be present during burning. Visitors would not be 

displaced. There are no units directly adjacent to White Rock Campground, but within onequarter of a mile, units (approximately 21 acres total) would be precommercial thinned. 

Vegetation treatments would be evident in and around dispersed campsites. Some users may be 

temporarily displaced while thinning activities occurred. This may increase camping at other 

dispersed sites. 

Alternative 4 

Treatments would improve the long-term health of timber stands adjacent to the above camping 

areas (developed and dispersed sites), thus creating a more appealing natural setting. Visitors 

would be able to see the ‘before and after’ effects of vegetation treatments if they visit the sites 

frequently. Commercial harvest, precommercial thinning, and fuels activities would create short 

term (3-5 years) and long term (10-15 years) effects that would be evident to the casual visitor. 

Short-term impacts to the camping areas would be evident near some of the areas. Effects from 

commercial harvest activities would include increased noise and dust from logging operations, 

increased traffic from timber hauling, reduced visual quality due to logging slash, stumps, 

exposed dirt, smoke, and blackened ground and vegetation from underburning activities. In the 

long term, the visual quality would be enhanced as more large ponderosa pines develop and 

views of open, park-like stands become more frequent. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 138 

There are no units adjacent to Ochoco Divide Campground, but within one-quarter mile, units 

(approximately 88 acres total) would be underburned. Smoke would be present during burning. 

Visitors would not be displaced, but may encounter smoke. There are no units adjacent to White 

Rock Campground, but within one-quarter mile, units (approximately 29 acres total) would be 

commercially harvested and impacts from logging activities would be apparent to visitors. 

Ground disturbance associated with tractor logging systems and road construction activities may 

increase the potential for rockhounding because agates and thundereggs would be more exposed. 

The amount of rockhounding activities near White Rock Campground and White Fir Springs 

may increase. 

Vegetation treatments would be evident in and around dispersed campsites. Some users may be 

temporarily displaced due to loss of access during harvest activities. This may increase camping 

at other dispersed sites. 

Alternative 5 

Commercial harvest, precommercial thinning, and fuels activities would create short term (3-5 

years) and long term (10-15 years) effects that would be evident to the casual visitor. In the 

short term, there would be effects to visual quality, recreational experiences, and trails. The 

visual quality may be affected as visitors would see stumps, slash piles, bare soil, skid trails, 

smoke, and boundary tags. There would be decreased stand densities and fewer small trees 

which would open up the views of surrounding areas and natural features. In the long term, the 

visual quality would be enhanced as more large ponderosa pines develop and views of open, 

park-like stands become more frequent. 

The prescriptions in this alternative include leaving clumpier stand structures and leaving higher 

densities in moist areas. Treatments would improve the long-term health of timber stands 

adjacent to camping areas (developed and dispersed sites), thus creating a more appealing natural 

setting. 

There are no units adjacent to Ochoco Divide Campground, but within one-quarter of a mile, 

units (approximately 88 acres total) would be underburned. Smoke would be present during 

burning. Visitors would not be displaced. There are no units adjacent to White Rock 

Campground, but within one-quarter of a mile, units (approximately 36 acres total) would be 

commercially harvested and impacts from logging activities would be apparent to visitors. 

Ground disturbance associated with tractor logging systems and road construction activities may 

increase the potential for rockhounding because agates and thundereggs would be more exposed. 

The amount of rockhounding activities near White Rock Campground and White Fir Springs 

may increase. 

Vegetation treatments would be evident in and around dispersed campsites. Some users may be 

temporarily displaced due to loss of access during harvest activities. This may increase camping 

at other dispersed sites.

a proposed action. This effort may alter recreational use at developed and dispersed camping 

sites because motorized vehicle use would be restricted to designated roads, trails, and areas. 

However, until a proposed action is developed it is not possible to disclose the expected effects 

because the roads, trails, and areas that will be designated for motorized use is uncertain. 

There are no other planned or reasonable foreseeable activities that are expected to alter 

recreational use in dispersed and developed camping areas. 

Snow Parks 

Affected Environment 

Ochoco Divide, Bandit Springs, and Marks Creek Snow Parks are within the project area and are 

near or adjacent to Bandit Springs Recreation Area. The snow parks are located off of U.S. 

Highway 26, 25-30 miles northeast of Prineville. These parks require Sno-Park permits 

(between November 15 and April 30), are paved, and have toilets. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 140 

Environmental Consequences 

Alternative 1 

There would be no direct or indirect effects to the snow parks. Use at these sites is expected to 

continue. 

Alternatives 2, 4, and 5 

Ochoco Divide Snow Park is closed in the off-season; therefore, there would be no direct effect 

to visitors. The primary use period is from December 1 to March 15. Management activities 

would be conducted outside of the primary use season. Unit 502 (hardwood thinning in an aspen 

stand) is adjacent to the snow park. Within 0.25 miles of Ochoco Divide Snow Park, about 95 

acres would be underburned. Activities would be visible, such as scorched trees, smoke, slash 

piles, and stumps. Visual evidence of activities may be apparent to the casual forest visitor at or 

near these areas. Over time, large ponderosa pine trees would be more apparent. 

Bandit Springs and Marks Creek Snow Parks are accessible year round. Within 0.25 miles of 

Bandit Springs Snow Park, approximately 40 acres would be commercially harvested, 16 acres 

would be precommercial thinned, and 20 acres would be underburned. Within 0.25 miles of 

Marks Creek Snow Park, approximately 40 acres would be commercially harvested, 20 would be 

precommercial thinned, and 38 would be underburned. Activities would be visible, such as 

scorched trees, stumps, slash piles, and exposed dirt. There would be log haul traffic on Roads 

2630 and 2630-113; however, haul would be restricted on weekends. See Table 47 for the 

amounts of activities by alternative within 0.25 mile of these snow parks.

Precommercial thinning and underburning activities would have short-term impacts on users, 

such as noise from thinning activities and smoke during underburning. Blackened ground and 

vegetation, and slash and small stumps would be visible. Visual evidence of activities may be 

apparent to the casual forest visitor at or near these snow parks. Over time, large ponderosa pine 

trees would be more apparent. 

Within 0.25 miles of Ochoco Divide Snow Park, approximately 60 acres would be 

precommercial thinned and 41 would be underburned. Within 0.25 miles of Bandit Springs 
Chapter 3 - Affected Environment and Environmental Consequences

Snow Park, approximately 58 acres would be precommercial thinned and 17 acres would be 

underburned. Within 0.25 miles of Marks Creek Snow Park, approximately 34 acres would be 

precommercial thinned and 38 acres would be underburned. Activities would be visible, such as 

scorched trees, exposed stumps, slash piles, and exposed dirt. 

Cumulative Effects 

In 2005, the Forest Service published a rule (36 CFR 212) for providing motor vehicle access to 

the national forests and grasslands. When implemented, the rule prohibits use of motor vehicles 

outside or off designated roads, trails, and areas. Some trails, roads, and areas will be closed in 

the future and others will be designated for motorized travel. The implementation date is 

expected to be in 2009. The Ochoco National Forest is in the preliminary process of developing 

a proposed action. This effort is not expected to alter recreational use of these snow parks 

because the use of over-snow vehicles is exempted from the requirement to designate roads, 

trails, and areas for motor vehicle use. 

There are no other planned or reasonable foreseeable activities that are expected to alter use of 

these snow parks. 

Trails 

Affected Environment 

There are approximately 24.5 miles of designated trails within the project area. This includes the 

14 miles of cross-country ski trails in Bandit Springs Recreation Area (already discussed in the 

above section), 2.5 miles of cross-country ski trails from the Walton Lake area (Butterfield, 

Corral Loop, and Drop-Off Trails), 6 miles of the Wildcat Trail in Mill Creek Wilderness, and 

4.5 miles of designated snowmobile trails. The Snow Park Tie Trail is a 2.5-mile long 

snowmobile trail that connects Ochoco Divide Snow Park with the Marks Creek-Independent 

Trail. Two miles of the Marks Creek-Independent Mine snowmobile trail is within the project 

area boundary. 

User-created trails exist in and around the project area. The endurance ride trail includes three 

loop trails that go in and out of treatment units. The Mustang Loop is approximately 20 miles, 

the High Loop is 30 miles, and the Pony Loop is 12 miles. 

Environmental Consequences 

Alternative 1 

There would be no effects to the trails or trail use in the project area. Trail maintenance 

activities would continue. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 142 

Alternatives 2, 4, and 5 

All of the action alternatives include activities near or adjacent to trails. Commercial harvest, 

precommercial thinning, and fuels activities would create short term (3-5 years) and long term 

(10-15 years) effects that would be evident to the casual visitor. Visitors would see stumps, 

piles, bare soil, smoke, and boundary tags. Trails that lie within or adjacent to commercial 

harvest units would be impacted directly from logging operations and post-harvest activities 

including noise, dust, logging traffic, altered scenery from slash or thinning, timber falling, and 

skid trails. As a result, the natural recreation experience may be altered due to short term 

disturbance of solitude and primitiveness. In the long term, the visual quality would be enhanced 

as more large ponderosa pines develop and views of open, park-like stands become more 

frequent. 

Precommercial thinning activities would leave small diameter (9 inches dbh) trees on the ground 

after they have been cut. Thus, traveling off of trails and roads would be more difficult for 3-8 

years until slash from logging and precommercial thinning is burned. Mountain bikers would 

have a difficult time if riding off trails and roads, but hikers and horseback riders would still be 

able to step over the small trees. To lessen the impacts to designated cross-country ski trails, 

there would be limited times to conduct logging operations. Prior to the use season, any logging 

slash on designated trails would be removed. Landings would not be located on designated 

trails. To lessen the impacts on the endurance ride held the third weekend in July, the portions of 

the permitted trail that are within the project area would have all slash pulled back from the trail 

2 weeks prior to the event. See Tables 48 and 49 for the amount of trails and snowmobile trails 

within/adjacent to units by alternative. 

Alternative 3 

Activities would focus in stands which have abundant numbers of small (less than 9 inches dbh) 

trees. Small tree densities would be decreased, single-storied open conditions would become 

more abundant, and fire-tolerant ponderosa pine and larch would be maintained. Precommercial 

thinning and fuels activities would create short term (3-5 years) and long term (10-15 years) 

effects that would be evident to the casual visitor. In the short term, the visual quality may be 

affected as visitors would see exposed stumps, piles, bare soil, smoke, and boundary tags. The 

visible stumps would be smaller and, therefore, would deteriorate faster. There would be 

decreased stand densities and fewer small trees which would open up the views of surrounding 

areas and natural features. There would be reduced screening along the trails due to the decrease 

in small diameter trees. In the long term, the visual quality would be enhanced as more large 

ponderosa pines develop and views of open, park-like stands become more frequent. 

The scatter/lop fuel treatment would leave more small trees scattered on the ground. Traveling 

off of trails and roads would be more difficult for 3-8 years until slash from precommercial 

thinning is burned. Thus, mountain bikers would have a difficult time if riding off trails and 

roads, but hikers and horseback riders would still be able to step over the small trees. The 

activity area would not be closed and summer users would not be temporarily displaced. There 

would be no conflicts between recreation users and logging traffic.

In 2005, the Forest Service published a rule for providing motor vehicle access to the national 

forests and grasslands. When implemented, the rule prohibits use of motor vehicles outside or 

off designated roads, trails, and areas. Some trails, roads, and areas will be closed in the future 

and others will be designated for motorized travel. The implementation date is expected to be in 

2009. The Ochoco National Forest is in the preliminary process of developing a proposed 

action. This effort is expected to alter trail use. However, until a proposed action is developed it

is not possible to describe the expected effects because the roads, trails, and areas that will be 

designated for motorized use is uncertain. 

There are no other planned or reasonable foreseeable activities that are expected to alter trail use 

in the project area. 

Wilderness 

Affected Environment 

The Mill Creek Wilderness encompasses 17,400 acres; 3,668 acres are within the project area. 

The Mill Creek Wilderness is the largest wilderness on the Ochoco National Forest and is the 

most heavily used. Use is primarily due to easy access and proximity to the city of Prineville. 

Elevations range from 3,725 to 6,640 feet above sea level. The terrain varies from the rugged, 

rocky cliffs of Desolation Canyon to the flat meadows of Bingham Prairie. Spectacular rock 

outcrops are present at Twin Pillars and Whistler Point. Many users accessing the eastern third 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 144 

of the wilderness camp or park at White Rock Campground and hike or ride horseback on the 

Wildcat Trail. There are also several dispersed campsites along the eastern boundary that 

receive heavy use during the fall hunting months. Other dispersed campsites exist within the 

wilderness area and are primarily located at springs, along streams, adjacent to meadows, or 

other attractive and accessible features. Management emphasis for this area is to protect the 

wilderness ecosystem and to maintain a natural setting and preserve solitude. 

In August and September 2000, the Hash Rock Fire burned 14,236 acres of the Mill Creek 

Wilderness, including 2,846 acres within the Marks Creek Watershed. The Hash Rock Fire 

damaged approximately 15.5 miles of trail in the Mill Creek Wilderness. These trails have been 

repaired. These trails are scheduled to be maintained annually. 

Environmental Consequences 

Alternative 1 

There would be no direct or indirect effects to the wilderness area. Recreation users would 

continue to access and enjoy the wilderness. 

Alternative 2 

There would be no direct effects to the Mill Creek Wilderness. Where commercial harvest units 

border the wilderness, users may encounter evidence of logging operations and post-logging 

treatments such as noise, stumps, slash piles, smoke, and blackened vegetation. Similar evidence 

of thinning and underburning activities would also be apparent. Over time, the health of 

remaining trees would be improved, which in turn, would improve scenic quality. 

Roads that are reconstructed within 0.25 miles of the wilderness boundary would be closed to 

minimize illegal motorized access in the wilderness. Within 0.25 miles of the wilderness 

boundary, there would be approximately 0.2 miles of new road construction and 0.4 miles of 

road reconstruction. After commercial harvest activities, the new road would be 

decommissioned. Decommissioned roads would be scarified, seeded, and water barred after use. 

The reconstructed road would be closed when done using it. Visuals may be affected as road 

beds would be evident in the long run but would eventually become overgrown with vegetation. 

Recreation users would continue to access the wilderness. Approximately 1.3 miles of the 

Wildcat Trail are within or adjacent to units. Users may encounter noise, dust, and smoke if they 

are present when these activities occur. As a result, the natural recreation experience may be 

altered due to short term disturbance of solitude and primitiveness. See Table 50 for number of 

miles of the Wildcat Trail within/adjacent to units for all alternatives. 

Alternative 3 

There would be no direct effects to the wilderness area. Where precommercial thinning units 

border the wilderness, indirect effects include noise and visual evidence from thinning and 

underburning activities such as chainsaw noise, smoke, and blackened vegetation. Over time, 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 145 

the health of remaining trees would be improved, which in turn, would improve the scenic 

quality. No road construction or commercial harvest would occur. Recreation users would 

continue to access the wilderness. Approximately 0.8 miles of the Wildcat Trail are within or 

adjacent to units. Users may encounter noise, dust, and smoke if they are present when these 

activities occur. As a result, the natural recreation experience may be altered due to short term 

disturbance of solitude and primitiveness. 

Alternative 4 

There would be no direct effects to the Mill Creek Wilderness. Where commercial harvest units 

border the wilderness, users may encounter evidence of logging operations and post-logging 

treatments such as noise, stumps, slash piles, smoke, and blackened vegetation. Similar evidence 

of thinning and underburning activities would also be apparent. Over time, the health of 

remaining trees would be improved, which in turn, would improve scenic quality. There would 

be no road construction or reconstruction within 0.25 miles of the wilderness boundary. 

Recreation users would continue to access the wilderness. Approximately 1.1 miles of the 

Wildcat Trail are within or adjacent to units. Users may encounter noise, dust, and smoke if they 

are present when these activities occur. As a result, the natural recreation experience may be 

altered due to short term disturbance of solitude and primitiveness. 

Alternative 5 

There would be no direct effects to the Mill Creek Wilderness. Where commercial harvest units 

border the wilderness, users may encounter evidence of logging operations and post-logging 

activities such as noise, stumps, slash piles, smoke, and blackened vegetation. The prescriptions 

in this alternative include leaving clumpier stand structures and leaving higher densities in moist 

areas. In the long term, the visual quality would be enhanced as more large ponderosa pines 

develop and views of open, park-like stands become more frequent. Treatments would improve 

the long-term health of timber stands, thus creating a more appealing natural setting. There 

would be no road construction or reconstruction within 0.25 miles of the wilderness boundary. 

Recreation users would continue to access the wilderness. Approximately 1.3 miles of the 

Wildcat Trail are within or adjacent to units. Users may encounter noise, dust, and smoke if they 

are present when these activities occur. As a result, the natural recreation experience may be 

altered due to short term disturbance of solitude and primitiveness

the wilderness. 

Soils 

Compaction and Displacement 

Affected Environment 

The project area contains a wide variety of soils. Soils in the project area may be affected by 

erosion, compaction, and/or displacement. The potential for effects to soils is directly related to 

the number of acres of each activity proposed. 

To maintain site productivity, the Forest Plan includes a standard for soil compaction and 

displacement. At a minimum, at least 80 percent of the activity area should be in a noncompacted/non-displaced condition within 1 year of any management activity. The standard is 

applied at an individual scale such as a unit of a timber sale. The January 10, 2007, Soils Report 

for this project more fully describes the soil standard and can be found in the project record. 

Detrimental soil conditions result from compaction, displacement, and charring. Compaction is 

the packing together of soil particles by exerting force at the soil surface and a resulting increase 

in soil density. Roads, log landings, and skid trails are typically areas that are detrimentally 

compacted during commercial timber harvest activities. Displacement is the movement or 

rearrangement of the soil so that normal processes are affected. Displaced soils are often 

loosened and are more susceptible to erosion. Roads, log landings, and skid trails are typically 

areas that are detrimentally displaced during commercial timber harvest activities. Soil charring 

can occur when concentrations of fuels are burned and the soil becomes superheated. This 

causes loss of organic matter and hydrophobic soil conditions can result from the cooked waxes 

and resins in the surface ash layer. Typically, charring occurs on landings where large piles 

(concentrations) of slash are burned. Burning of hand and grapple piles does not typically result 

in detrimental charring because of the small pile size. 

The existing condition of the soils resource was determined by the Forest soil scientist and other 

members of the interdisciplinary team. A combination of local knowledge, walk-through 

transecting, and aerial photo interpretation was used to determine existing soil disturbance for 

each unit. This unit-by-unit evaluation of existing soils condition was completed and is 

contained in Appendix B to this EIS. This unit-by-unit evaluation includes an assessment of 

harvest units and grapple piling units. Other non-harvest activities were not included because 

they are not expected to cause detrimental soil disturbance. Existing disturbance was quantified 

to the nearest ten percent bracket (0-10, 10-20, etc.), estimates were made as to tilling potential 

based on soil type and slope, and unit-specific mitigations identified where needed to ensure 

compliance with the soil standard. The evaluation of existing conditions reveals that more than 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 147 

half of the acres included in commercial harvest units currently exceed 20 percent detrimental 

soil conditions. 

Environmental Consequences 

Tractor (ground-based) logging systems can cause the highest amount of soil impacts and can 

result in exceeding the soil standard if not carefully designed and actively monitored. Classic, 

rubber-tired skidders and skidding crawler-type tractors are used on an average 100-foot skid 

trail spacing to skid logs to the landings which are accessed by roads. The main skid trails 

comprise the majority of the detrimental disturbance, which is largely compaction and 

displacement. Skid trails on an average of 100-foot spacing contribute roughly 10-15 percent 

detrimental disturbance in an average unit with landings and roads making up an additional 5 and 

2 percent, respectively. Overall, potential for detrimental soil conditions is 17-22 percent per 

entry; this does not include any mitigation or other measures to reduce potential impacts, nor 

does it include existing levels of detrimental disturbance. Past harvest practices have often led to 

unacceptable amounts of detrimental soil conditions. Current practices confine disturbance 

largely to existing skid trails and landings from prior entries. 

Helicopter logging systems are used on steeper slopes, in areas where road building is difficult or 

expensive, and/or in areas where tractor logging would cause unacceptable resource effects. The 

economic costs are higher for this type of logging and the impact to the soil resource are lower. 

Detrimental disturbance averages 2 to 5 percent per entry, primarily on roads and landings. 

Skyline logging systems are used largely on steeper slopes where there is sufficient deflection for 

the use of cable operations. They usually have an access road at the top of the unit or drainage 

with landings along the roads. Detrimental disturbance averages 6 to 12 percent per entry, 

primarily on roads, skyline corridors, and landings. 

Grapple piling of slash is used to reduce fuel loadings in harvest units. The objective is to lessen 

fuel loading and break up fuel continuity, not remove all fuel from a site. Grapple piling is 

achieved using boomed equipment that is required to stay on previously disturbed areas. Fuels 

objectives can be achieved with little or no additional soil impacts. 

Yarding with tops attached (YTA) is another treatment to reduce fuel loadings in harvest units. 

This treatment results in lower fuel amounts inside the harvest unit by concentrating slash at the 

log landings. This requires larger landings and more intense heat results when the landing piles 

are burned, producing more charred soil. Since the landings are situated most often on top of old 

landings and disturbed areas from prior activities, this usually does not result in a net increase in 

detrimental soil conditions. For tractor harvest units, YTA skid trails are somewhat wider due to 

the sweeping action of the limbs. 

Recent monitoring results on the Ochoco National Forest (Blackbear Timber Sale) show that 

detrimental soil conditions can be kept within acceptable levels using tractor logging systems. 

This requires that design elements be followed and that the need for tilling be evaluated after 

harvest activities. Reuse of existing detrimentally disturbed areas can result in little or no 

additional impacts to soils. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 148 

Several other types of treatments are also proposed which generally do not result in detrimental 

soil impacts. These treatments include: precommercial and hardwood thinning, underburning, 

and activity-fuels hand piling and burning. Soil disturbance that may result from these activities 

is limited in scale, and of such a light intensity, that no detrimental compaction, displacement, or 

charring is expected. These activities do not involve the use of heavy equipment such as 

bulldozers. No measurable detrimental effects to the soil resource are expected from these 

activities under any alternative. 

Soil tilling is proposed to alleviate detrimental compaction. It is feasible in deeper ash soils on 

slopes of 30 percent or less. Heavy equipment is used and tilling would be focused on skid trails 

and landings which are excess to current and future management needs.

*The actual amount of tilling would be based on post-harvest monitoring. These acres are the minimum acres that 

are estimated to be required to meet the soil standards on a unit-by-unit basis (see Appendix B). 

Alternative 1 

This alternative is the no action alternative and would not affect soils. Existing natural processes 

would continue. No soil tilling would be performed. Recovery of existing soil compaction 

would occur through natural processes. These processes include frost heaving in the top 4 to 6 

inches of soil and biopedoturbation (soil disturbance by organisms such as rodents, insects, 

arthropods, and worms). This natural process can take hundreds of years to fully restore 

damaged soils. Fire intensities would potentially be more severe resulting in more detrimental 

charring and hydrophobic soil conditions. 

Fuels reductions would not occur thereby increasing the risk of increased oxidation and 

mineralization of nutrients such as nitrogen and potassium. This may result in increased fire 

severity which can reduce site productivity (Harvey et al. 1991). 

This alternative would comply with the regional and Forest Plan soil standards. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 149 

Alternative 2 

This alternative includes the most timber harvest, as well as the most ground-based harvest. This 

alternative has the greatest potential to increase the amount of detrimental soil compaction, 

displacement, and charring. This alternative has unit specific mitigations and practices identified 

which would ensure that activity units meet the soil standards (see unit-by-unit soils analysis in 

Appendix B and Chapter 2, design elements). These include design of logging systems, 

avoidance of specific areas, and soil tilling. This alternative creates approximately 30 acres of 

detrimental soil compaction and displacement due to construction of new roads. This alternative 

would result in approximately 120 acres of tilling to alleviate detrimental soil compaction. 

Some detrimental soil charring is expected to occur under the grapple piles and at landings where 

YTA occurs. This detrimental charring would be of a low percentage (estimated to be 5 to 6 

piles per acre at 100 square feet/pile which yields 1.1 to 1.3 percent impacts which are mostly on 

existing trails and landings). Underburning would result in a very small amount of detrimental 

charring in areas where existing fuel loadings are high. This is estimated to occur only on a 

fraction of 1 percent. 

This alternative would comply with the regional and Forest Plan soil standards. 

Alternative 3 

This alternative has the least potential to increase the amount of detrimental soil disturbance. No 

soil tilling would be performed. Existing natural processes would continue. Recovery of 

existing soil compaction would proceed at a natural rate. Some small areas of charring may 

occur under fuel concentrations, but would be limited in scope and expected to be less than 5 

percent of the treated acres. This alternative would result in no net increase in the amount of 

area which exceeds the 20 percent detrimental soil condition standard. 

This alternative does not include grapple piling or commercial harvest. Underburning would 

result in a small amount of charring in areas where existing fuel loadings are high. This is 

estimated to occur only on a fraction of 1 percent of the area burned. There would be no net 

increase of detrimental soil conditions. The failure to thin young sawtimber component (from 9 

to 14 inches dbh) would increase per acre standing fuel loadings which would increase fire 

intensity and severity in the future especially in reburn conditions (Shank 2004). 

This alternative would comply with the regional and Forest Plan soil standards. 

Alternative 4 

This alternative proposes less harvest and less tractor harvest than Alternative 2. This alternative 

has unit specific mitigations and practices identified which would ensure that all activity units 

meet the soil standards (see Appendix B). These include design of logging systems, avoidance 

of specific areas, and soil tilling. Implementation of this alternative would result in 

approximately 95 acres of tilling to alleviate detrimental soil compaction, both existing and new. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 150 

This alternative includes approximately 8 additional acres of detrimental soil impact due to 

construction of roads. 

Some detrimental soil charring is expected to occur under grapple piles and at landings where 

YTA occurs. This detrimental charring would be of a low percentage (estimated to be 5 to 6 

piles per acre at 100 square feet/pile which yields 1.1 to 1.3 percent impacts which are mostly on 

existing trails and landings). Underburning would result in a very small amount of detrimental 

charring in areas where existing fuel loadings are high. This is estimated to occur only on a 

fraction of 1 percent. 

This alternative would comply with the regional and Forest Plan soil standards. 

Alternative 5 

This alternative proposes less harvest and less tractor harvest than Alternatives 2 and 4. This 

alternative has unit specific mitigations and practices identified which would ensure that all 

activity units meet the soil standards (see Appendix B). Implementation of this alternative would 

result in approximately 88 acres of tilling to alleviate detrimental soil compaction, both existing 

and new. This alternative includes approximately 6 acres of detrimental soil impact due to 

construction of roads. 

Some detrimental soil charring is expected to occur under the grapple piles and at landings where 

YTA occurs. This detrimental charring would be of a low percentage (estimated to be 5 to 6 

piles per acre at 100 square feet/pile which yields 1.1 to 1.3 percent impacts which are mostly on 

existing trails and landings). Underburning would result in a very small amount of detrimental 

charring in areas where existing fuel loadings are high. This is estimated to occur only on a 

fraction of 1 percent. 

This alternative would comply with the regional and Forest Plan soil standards. 

Cumulative Effects 

Analysis of the entire project area indicates that approximately 15 percent of the area has 

detrimental soil conditions. Existing detrimental soil conditions are primarily related to past 

harvest activities, road building, and activities on private land. There was a slight increase (10 

acres) in detrimental soil conditions due to fire lines built during the suppression of the Hash 

Rock Fire. Rehabilitation of all fire lines has been completed. Detrimental soil conditions 

related to the fire itself were low and limited to localized charring. Post-fire monitoring within 

Harpo Timber Sale units that were burned indicates little soil damage caused by the fire and 

vegetative recovery of 75 to 80 percent has occurred. Other rehabilitation efforts associated with 

the Hash Rock Fire include culvert removal, road closure, and riparian/hardwood planting. None 

of these activities increased the amount of detrimental soil conditions across the project area. 

The most recently logged sales in the project area, Marks and Harpo, have had the harvest 

activities complete for several years. Post-harvest monitoring indicated that soil tilling was not 

needed to decrease detrimental soil conditions as a result of the harvest activities. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 151 

The Pick-Up Salvage Sale (completed in 2002) removed already downed trees utilizing existing 

roads, skid trails, and landings. It did not contribute additional detrimental effects on the soil 

resource in the project area. The Cougar Salvage Sale (completed in 2006) removed dead trees 

and did not contribute additional detrimental effects on the soil resource. 

Mass Wasting 

Affected Environment 

Massive rotational slump and earth flow landslides were the predominant land forming processes 

in the past. The dormant deep landslides, which shape the project area, were probably active 

throughout the past 1 million years. They were probably triggered by a combination of tectonic 

activity and high precipitation. They naturally adjust as the streams cut the toes of the landslide 

debris and as natural fires, insect and disease infestations removed vegetation, allowing increased 

precipitation to saturate the soils. Numerous seeps and springs are present all across the project 

area, confirming the scrambled nature of the landform. 

Based on an air photo interpretation, the project area has a series of dormant and active landslide 

terrain composed of scarps and debris lobes. Seven small active landslides (2.5 to 4 acres in 

size) are located on midslopes, within larger dormant landslide terrain, on the Clarno Formation. 

One active landslide (4 acres) is contained within a small draw on Road 3350-230, which crosses 

the active landslide midslope. A rock blanket has been constructed on the cutslope adjacent to a 

more recent fill failure, which occurred during the winter of 1997. The culvert in the draw 

failed, causing a new translational slide on the already active slope. This site has been 

reconstructed. Road 3350-230 is currently under a year-round wildlife closure and has a locked 

gate at the junction with Road 3350-200. A 1.5-acre rotational landslide is adjacent to Road 

3300-503 in the headwaters of Salmon Creek; this landslide was reactivated in 1998. One debris 

flow is in T. 13 S., R. 18 E., Section 13 near the Mill Creek Wilderness trail. The fourth debris 

flow is in a Harpo Timber Sale unit. The debris flow occurred in 1998. The fluid debris blocked 

Road 3350-200, flowing across the road and down the slope toward Road 3350-230. The fifth 

landslide is a road-related rotational slide on Road 2610-050 on the east side of Marks Creek (T. 

13 S., R. 19 E., Section 31). The fill has been repaired. The sixth active landslide is on Road 

2600-012 (T. 13 S., R. 19 E., Section 16) in the Shamrock area. This landslide terrain 

reactivated in 1998. The subsequent road failure was repaired in 2001. The draw has active 

tension cracks, jackstraw trees, and a sag pond. The seventh landslide (3.3 acres) is located in T. 

13 S., R. 18 E., Section 13, between Units 119 and 120. 

The majority of the project area (87%) is at a low to moderate risk for reactivation by 

management activities such as road construction or harvest, or by the continued weather pattern 

of higher precipitation. Eighteen acres are active landslide terrain. Approximately 13 percent of 

the project area is within mapped dormant landslide terrain. The dormant landslide terrain 

extends across the length of the project area and is considered to be at moderate risk for 

reactivation by management activities such as road construction or harvest, or by the continued 

weather pattern of higher precipitation. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 152 

The majority of the dormant landslide originates on Clarno Formation within the project area. 

Perched ponds and springs are located along the benches nestled within the landslide scarps. 

When the dormant landslides were more active, they contributed a portion of the existing 

sediment currently occupying the flood plains of the stream courses. Based on limited stream 

surveys, there is evidence that the stretches of Jim Elliott and Sears Creeks with greater than 20 

percent cutbank erosion are adjacent to the toes of dormant landslides in the upper reaches. 

History has shown the land to be responsive to rain-on-snow events, especially below the 4,500-

foot elevation. When the landslide debris and the shallow ash soils are saturated, there is 

potential for an increase in slope movement, which has resulted in debris flows and small 

rotational landslides within the project area. Above 4,500 feet elevation, the ground is generally 

still frozen and snow covered. Fewer debris flows and rotational slides occur in this region. 

Construction of roads across landslide debris has the potential to compact the debris, creating a 

dam-like feature, which may collect water upslope, increasing pore water pressure to the point of 

failure. Minimizing the height of cuts and fills and maintaining adequate drainage help to reduce 

potential sediment delivery. The construction methods and design criteria which incorporate 

geotextile, filter rock, reinforced rolling dips, adequately sized pipes, placement frequency, and 

surface aggregate will reduce the risk of road-related failures. When the unconsolidated 

landslide debris is saturated, there is a potential for movement with subsurface water flow down 

slope. Construction of roads and trails on active and dormant landslides may accelerate erosion 

by changing the subsurface flow patterns, causing increases in pore water pressure, and 

subsequent reactivation of slope movement. Portions of the existing road system were 

constructed on dormant and active landslides. 

Management activities have the ability to affect the stability of the land. When there is a change 

in the ground water flow through the unstable terrain, the potential is increased for slope 

movement. Rapid shallow debris flows and deeper rotational slides can result, altering the 

vegetation potential and potentially releasing sediment into the stream systems, depending on 

proximity to the riparian areas. Careful alignment of trails and roads, in addition to streamside 

protection will help to reduce sedimentation. Changes in precipitation patterns and climate will 

have their own effects on the erosion rates. 

Although central Oregon is no longer affected by the past moist climate, which contributed to the 

generation of the landslide features shaping the mountains today, there is the potential to 

reactivate the dormant landslides. Soil compaction due to management activities across 

landslide debris may change the water flow through the soil pores, potentially affecting the 

stability of the slope. When the toe slopes of the deep seated landslides abut live streams, they 

are prone to active erosion. Through time, the landslide debris has reached an equilibrium on the 

hill slopes. As the stream erodes the toe slopes, the natural balance is upset. Accelerated erosion 

can occur, causing a decrease in water quality as additional sediment is introduced into the 

system. The goal is to not increase the pace of mass wasting events beyond the natural 

background. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 153 

Environmental Consequences 

Alternative 1 

Under this alternative, no timber harvest, road construction, or other activities that would affect 

dormant and active landslide terrain would occur. The natural process of erosion under the 

current precipitation pattern would continue. There would be no direct, indirect, or cumulative 

effects. 

Alternative 3 

The proposed treatments of precommercial thinning and underburning would have no direct 

effects on increasing slope instability. Indirectly, the activities would encourage increased 

growth of the vegetation, which would increase the evapotranspiration and increase slope 

stability. 

Alternatives 2, 4, and 5 

The intensity and style of management activity on landslide terrain, in the vicinity of seeps and 

springs, may potentially change the drainage pattern which increases the risk for instability. 

Generally, commercial harvest does not measurably alter groundwater movement, except in the 

vicinity of seeps and springs. Commercial harvest is not expected to substantially reduce the 

amount of water taken up by the trees through evapotranspiration. Reducing the amount of 

evapotranspiration would leave more groundwater in the slope, which has the potential to change 

slope stability. 

The acres of dormant and active landslide terrain are spread across the project area. Alternative 

2 proposes management on more acres in dormant landslide terrain than Alternatives 4 or 5. 

Alternative 2 includes 1,423 acres of commercial harvest on dormant landslide terrain. 

Alternative 4 includes 1,062 acres of commercial harvest on dormant landslide terrain. 

Alternative 5 proposes the least amount of harvest on dormant landslide terrain; it includes 904 

acres. Helicopter and skyline logging systems are less likely to increase instability than a tractor 

logging system which tends to compact the soil, changing groundwater flow patterns, and 

potentially altering slope stability. 

Units located on the upper slopes of dormant landslide scarps have a slightly increased potential 

for reactivating the landslide debris on the lower slopes when combined with higher precipitation 

or a rain-on-snow event like those that occurred in 1997, due to the potential increase flow of 

groundwater to the lower slopes. Alternative 5 would have slightly less of an effect than 

Alternative 4 and definitely less than Alternative 2. 

There are areas of active landslides on or near Roads 3350-200, 3350-230, 2610-050 and 3300-

503. The use of these roads for haul is not expected to increase the potential for mass wasting. 

Road 3300-503 is expected to self-close, as the landslide scarp retreats into the roadbed. Under 

all the alternatives, Road 3300-503 and 3350-200 are proposed for reconstruction, which would 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 154 

reduce the potential for future failures by replacing culverts, modifying cross drains, and 

ensuring proper drainage is maintained. 

Cumulative Effects 

Potential risk for an increase in sediment transport due to mass wasting is low to moderate for all 

the action alternatives. There are no past, ongoing, or reasonably foreseeable activities that 

would reduce slope stability and increase mass wasting. 

Visual Quality 

Affected Environment 

The Forest Plan allocated some areas to visual management, including corridors along U.S. 

Highway 26, Forest Roads 27, 2630, and 2210, and recreation sites such as Bandit Springs 

Recreation Area. The Visual Quality Objectives for these areas are retention or partial retention 

which means that the general emphasis in these areas is to maintain the natural-appearing 

character of the forest. There is an estimated 7,564 acres in the project area that are included in 

these visual management allocations. Approximately 5,586 acres are included in the U.S. 

Highway 26 Scenic Corridor, 1,580 acres in the Bandit Springs Recreation Area, 55 acres in the 

Forest Road 27 corridor, 292 acres in the Forest Road 2630 corridor, and 51 acres in the Forest 

Road 2210 corridor. 

The existing scenery has a variety of disturbed and undisturbed areas. Human-caused activities 

have altered the natural-appearing landscape. Diverse vegetation stands and species (with 

various age, size classes, and health conditions) can be found throughout the project area. These 

vegetation stands include: ponderosa pine, lodgepole pine, western larch, Douglas-fir, grand fir, 

white fir, and riparian species. They provide strong diverse lines and textural and color patterns 

broken up only by occasional filtered-view openings into the foreground landscape. 

Although the existing forest conditions may appear natural to a casual visitor, the forest 

conditions are not natural. Older trees are being suppressed by the densely stocked understory 

due to the change in fire regime caused by fire exclusion. Densely stocked forest and canopy 

closure, due to fire exclusion, has led to the loss of the open, park-like ponderosa pine stands 

historically found within the area. Overstocked and dense stands in parts of the project area have 

led to serious fire risk. The natural processes can no longer function as they did historically 

because of these dense stand conditions. 

The competition for available space, nutrients, and the encroachment from shade-tolerant 

understories is prevalent, especially along the travel and scenic corridors (within 0.25 miles). 

The depth-of-field view deep into the forest is restricted to mostly the immediate foreground area 

of the landscape due to the high level of vegetation. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 155 

Environmental Consequences 

Alternative 1 

Under this alternative, the existing vegetation within the project area would not be altered or 

changed by any management activity. Scenery would remain essentially the same during the 

short-term duration (0-5 years) and may be adversely altered through time (5 years and longer) 

as multi-strata conditions continue to increase. Encroachment by shade-tolerant species would 

continue and stand densities would continue to increase. Views of open, park-like stands of 

older and larger ponderosa pine would become less frequent. 

Alternative 2 

Approximately 4,576 acres within visual corridors would be treated to enhance long-term scenic 

quality through commercial thinning, precommercial thinning, and underburning activities. 

After implementation, the proposed activities within visual management corridors would have 

short-term (0 to 5 years) effects on scenery. Stumps, slash, and smoke during burning activities 

would be evident. However, in the long-term, scenery would be enhanced and the vegetation 

would be moved to more sustainable conditions. Sufficient levels of residual trees would remain 

on site to meet desired conditions. Table 52 displays the amount of activities within visual 

corridors for all alternatives. 

Management activities would occur within the U.S. Highway 26 Scenic Corridor, Bandit Springs 

Recreation Area, and travel corridors along Forest Roads 27, 2630, and 2210 within retention 

and partial retention visual management allocations. Commercial harvest and precommercial 

thinning would occur within densely stocked stands. Treatments would enhance and maintain 

scenery by removing understory trees. This would allow the development of more large 

ponderosa pine and views of large ponderosa pine would become more frequent. 

There would be approximately 11.2 miles total of road work within the visual corridors. This 

includes approximately 3 miles of new road construction and closing the roads after timber 

hauling and 0.4 miles of new road construction and decommissioning the roads after timber 

hauling. 1.3 miles of existing roads would be decommissioned and 2.8 miles of existing roads 

would be closed following timber haul. Newly constructed road beds would be evident in the 

long run but would eventually become overgrown with vegetation. Decommissioned roads 

would be scarified, seeded, and water barred after use. However, only 0.2 miles of a newly 

constructed road would take off directly from the visual corridor on Forest Road 27. This new 

road would be apparent to the visitor, but it would be decommissioned following commercial 

harvest activities. The other proposed new roads would not take off directly from the visual 

corridors so new road construction would not be apparent to the casual visitor. 

“Filtered views” deep into the forested landscape, including views into the gentle rolling hills, 

would be created. This would enhance the existing scenery. Open, park-like stands of older 

structure ponderosa pine stands would be more readily seen along travel corridors. The “tunnel” 

effects currently found throughout the project area would be reduced and would become 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 156 

diversified with more openings in treated areas. After the short-term effects of treatment 

activities (disturbed soil, slash, scorched vegetation) have recovered, the diverse scenic views are 

expected to enhance a visitor’s experience along these corridors. 

Forest Plan direction would be met with the retention of residual trees, post-treatment clean up 

activities, and implementation of design elements. This alternative would better enhance the 

visual quality than the other alternatives. 

Alternative 3 

Approximately 4,414 acres within visual corridors would be treated to enhance long-term 

scenery through precommercial thinning and underburning activities. Under this alternative, the 

effect on scenery is expected to be less than the other alternatives since only small understory 

trees would be removed. 

Precommercial thinning and underburning would have short term effects on scenery, such as 

stumps, slash, scorched vegetation, and smoke. However, in the long-term, scenery would be 

enhanced and the vegetation would be moved toward more sustainable conditions. Sufficient 

levels of residual trees would remain on site to meet desired conditions. 

Management activities would occur within the U.S. Highway 26 Scenic Corridor, Bandit Springs 

Recreation Area, and travel corridors along Forest Roads 27, 2630, and 2210 within rRetention 

and partial retention visual management allocations. The long term (20 years and longer) scenic 

quality within the treatment areas may improve slightly or would remain the same as the existing 

condition. Less alteration to the scenery would occur due to the removal of smaller, understory 

trees. 

There would be no new road construction. 

“Filtered” views would only be created in two-storied stands which do not have a mid-canopy 

layer. Fewer views of open ponderosa pine would be visible than in the other action alternatives. 

The retention of green trees following treatment would maintain scenery. 

The Forest Plan direction would be met through retention of residual trees, post-treatment clean 

up activities, and implementation of design elements. This alternative would move less of the 

area toward the desired future condition for scenic resources than the other action alternatives. 

Alternative 4 

Approximately 4,657 acres within visual corridors would be managed to enhance long-term 

scenic quality through commercial thinning, precommercial thinning, and underburning 

activities. Management activities within the visual corridors would have a short-term effect on 

scenery due to slash, stumps, blackened vegetation, and smoke. However, in the long-term, 

scenery would be enhanced and the vegetation would be moved to more sustainable conditions. 
Chapter 3 - Affected Environment and Environmental Consequences

Management activities would occur within the U.S. Highway 26 Scenic Corridor, Bandit Springs 

Recreation Area, and travel corridors along Forest Roads 27, 2630, and 2210 within visual 

management allocations. Commercial harvest and precommercial thinning would occur within 

densely stocked stands and would remove understory trees. Treatments would enhance and 

maintain scenery. This would allow the development of more large ponderosa pine and views of 

large ponderosa pine would become more frequent. 

There would be approximately 8.2 miles total of road work within the visual corridors. This 

includes approximately 0.8 miles of new road construction and closing the roads after timber 

hauling and 0.2 miles of new road construction and decommissioning the roads after timber 

hauling. 1.0 mile of existing roads would be decommissioned and 2.8 miles of existing roads 

would be closed following timber haul. Newly constructed road beds would be visible in the 

long run but would eventually become overgrown with vegetation. Decommissioned roads 

would be scarified, seeded, and water barred after use. One of the proposed new roads would 

take off directly from the visual corridor along Road 27; this road would be decommissioned 

following commercial harvest activities and would be apparent to the casual visitor for a period 

of time. 

“Filtered views” deep into the forested landscape, including views into the gentle rolling hills,

enhance the visual quality of the project area. 

Alternative 5 

Approximately 4,572 acres within visual corridors would be managed to enhance long-term 

scenic quality through commercial thinning, precommercial thinning, and underburning 

activities. Management activities within the visual corridors would have a short-term effect on 

scenery due to slash, stumps, blackened vegetation, and smoke. However, in the long-term, 

scenery would be enhanced and the vegetation would be moved to more sustainable conditions.

Water Quality 

Temperature and 303(d) list 

Affected Environment 

Marks, Little Hay, and Hamilton Creeks are on the 2004/2006 state 303(d) list of Water Quality 

Limited Water Bodies for summer water temperature. The 2004/2006 Oregon 303(d) list was 

approved by EPA on February 26, 2007. Table 53 displays the 7-day average, maximum water 

temperatures for stations on Marks Creek and its tributaries measured from 1997 through 2006. 

Water temperatures over threshold are indicated in bold. Water temperatures from 1994 through 

1996 are on file at the Lookout Mountain Ranger District. The state standard (Oregon Water 

Quality Standards (OAR) 340-041-0002(56) and 340-041-0004(5)(a)) indicates the 7-dayaverage maximum temperature of streams identified as having salmon and trout rearing and 

migration should not exceed 18.0 degrees C (64.4 degrees F). 

U.S. Highway 26 is immediately adjacent to a number of reaches on Marks Creek. The loss of 

shade and channelization resulting from the highway is a major contributor to higher 

temperatures in Marks Creek. The 2004/2006 303(d) list references 2002 data from Marks 1 

(below Peterson Creek) and Marks 2 (above Little Hay Creek). The 1997 data, shown in Table 

53 for Marks 3 (below Buck Creek) and Marks 4 (below Cornez Creek), support the extension of 

the listing to the upper reaches of this creek. Monitoring indicates that the floating 7-day 

maximum average water temperatures in most of Marks Creek range from the low to mid 70's. 

Decreases in base flows due to evaporation from Marks Pond, irrigation withdrawals in lower 

Marks Creek, and shallow groundwater use by homeowners are probably also contributing to 

higher summer water temperatures. Maximum 7-day floating average water temperatures in 

Marks Creek tributaries range from the high 60’s to mid 70’s in Crystal and Peterson Creeks to 

meeting state and INFISH standards in Hamilton and McGinnis Creeks. 

Monitoring of Hamilton Creek started in 2001, the year after the Hash Rock Fire, to evaluate the 

effects of the fire above the 2600-200 road. By 2003, the water temperatures had fallen back 

below threshold. Based on recent water temperature monitoring, Hamilton Creek should not be 

on the 303(d) list because the high temperatures were a temporary effect of the Hash Rock Fire. 

Other streams in the project area were monitored that are not on the 2004/2006 303(d) list. The 

station on McGinnis Creek was established to evaluate the effects of the Hash Rock Fire. The 

fire intensity in this area was lower than in Hamilton Creek and the water temperatures never 

exceeded the threshold. However, McGinnis Creek shows the same 3-year water temperature 

recovery observed on Hamilton Creek. The stations on Salmon Creek were established to 

evaluate the effects of conifer removal from aspen. The conifer trees have since died from a bark 

beetle infestation. Salmon Creek appears to be over threshold. The temperature monitoring site 

on Crystal Creek is between 0.1-0.2 miles above it’s confluence with Marks Creek. Monitoring 

data indicates it is above threshold. Rush Creek was over threshold in 1997, but only had a 7-

day average daily maximum water temperature of 63.83 degrees F in 1996.

No measurable increase in water temperatures, except in accordance with water quality 

standards, may result from management practices in the Spears project area on streams over the 

state water temperature standard threshold. The INFISH RMOs indicate there should be no 

measurable increase in the 7-day maximum average water temperature for the project area. 

Hamilton Creek water temperatures have recovered from the Hash Rock Fire and fell back below 

threshold in 2003. Little Hay Creek was under threshold during more than half of the years 

monitored. The 2003 temperature data does not look consistent with the temperature pattern of 

earlier and later years. This was probably due to a sampling error. The 2003 data should not 

have been used for determining impairment. Hamilton and Little Hay Creeks should not be on 

the 303(d) list based on temperature monitoring data. 

Reductions in solar input resulting from shading are a primary factor affecting stream 

temperature. Shade functions generally occur within 100-200 feet of the channel (Beschta et al. 

1987). 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 161 

The February 12, 2007, Spears Vegetation Project Hydrology Report contains additional 

information on 303(d) listed streams, stream shading, and temperature. 

Environmental Consequences 

Alternative 1 

There would be no activities within the RHCAs for streams on the 303(d) list. No reduction in 

shading would result from this alternative. There would be no increase in water temperatures. 

The temperature of streams that are on the 303(d) list as described above would not change. 

Alternative 2 

There would be about 147 acres of commercial harvest in Class I, II, and III RHCAs. These 

activities would not reduce shade on fish-bearing streams or non-fish-bearing perennial streams. 

The only commercial harvest within an RHCA on a 303(d) listed stream is in Unit 841 along 

Marks Creek. Commercial harvest in this unit would be accomplished using a helicopter logging 

system. Commercial harvest would only occur in the outer 100 feet of the 300-foot RHCA and 

would not reduce shade on Marks Creek. 

There would be about 723 acres of precommercial and hardwood thinning in Class I, II, and III 

RHCAs. Precommercial thinning within RHCAs occurs in RHCAs for 303(d) listed streams. In 

the Hamilton Creek RHCA, precommercial thinning would occur in Units 708 and 873. In the 

Little Hay Creek RHCA, thinning would occur in Unit 402 which is an aspen unit. In the Marks 

Creek RHCA, precommercial thinning would occur in Units 567, 840, and 841, and hardwood 

thinning would occur in Units 502 and 507. The height of trees, at various slopes and distances 

that provide shade during the period when peak temperatures occur, were calculated. Only trees 

less than this height would be thinned from units along perennial streams. Shade was not a 

consideration along intermittent streams since they should not affect peak water temperatures; 

however, some shade would be maintained in Class IV RHCAs to contribute toward meeting 

Riparian Management Objectives (RMOs). Shade monitoring of precommercial thinning within 

Class I and II RHCAs in 1998 found less than a one (1) percent change in shade readings when 

compared to shade readings taken prior to thinning (Fontaine 1998). Precommercial thinning 

would not reduce shade on streams, including 303(d) listed streams. There is a risk of conifer 

thinning in aspen stands reducing shade for a short time (up to 6 months); however, water 

temperatures would still meet state standards. 

There is a risk of prescribed fire reducing shade for a short time (up to 6 months); however, 

water temperatures would still meet state standards. Short-term increases in temperature (up to 6 

months) are allowed even on streams over threshold during activities designed to restore riparian 

vegetation (OAR 340-041-002(56) and 340-041-0004(5)(a)). Prescribed burning would occur 

within the RHCAs for 303(d) listed streams. Along Hamilton Creek, burning would occur in 

Units 708 and 873. Along Little Hay Creek, burning would occur in Units 861, 862, and 867. 

Along Marks Creek, burning would occur in Units 567, 832, 833, 838, 840, 841, 842, 901, 921, 

and 922. Burning would be accomplished when moisture conditions favor a low-intensity burn 

which would result in a mosaic of burned and unburned vegetation. Prescribed fire would not be

ignited within 50 feet of stream channels, although fire would be allowed to burn within this 50-

foot buffer. Approximately 38 percent of the RHCAs on fish-bearing streams and 38 percent on 

perennial non-fish bearing streams are in units with prescribed fire. It is estimated that 20 

percent of the area in the RHCA would burn with most of this being at low intensity and further 

away from the stream. There would not be any measurable increase in water temperatures on 

perennial streams. There is a potential to increase water temperature in intermittent non-fish 

bearing streams (Class IV) when they are flowing, but this should not result in a violation of state 

water quality standards because these streams go dry before peak water temperatures occur in the 

project area. 

There would be no measurable temperature change on any of the Class I-III streams, including 

303(d) listed streams, in the project area under any of the alternatives in the next 10 years. 

Activities proposed in RHCAs, including RHCAs for 303(d) listed streams, are designed to 

promote attainment of RMOs over time. Thinning conifers would increase the growth rates of 

residual conifers and hardwood and broadleaf species such as aspen, cottonwood, alder, and 

willow. Hardwood and broadleaf species are expected to increase in vigor and would provide 

additional shade. Increasing the growth rates of residual conifers would promote development of 

large trees that would become future large wood. As the amount of large woody material in 

streams increases over time, it would result in more pools which would help lower water 

temperatures. 

Alternative 3 

There would be 675 acres of precommercial thinning in Class I, II, and III RHCAs in this 

alternative. Precommercial thinning within RHCAs occurs in RHCAs for 303(d) listed streams. 

In the Hamilton Creek RHCA, precommercial thinning would occur in Units 708 and 873. In the 

Little Hay Creek RHCA, thinning would occur in Unit 402 which is an aspen unit. In the Marks 

Creek RHCA, precommercial thinning would occur in Units 567, 840, and 841, and hardwood 

thinning would occur in Units 502 and 507. The height of trees, at various slopes and distances 

that provide shade during the period when peak temperatures occur, were calculated. Only trees 

less than this height would be thinned from units along perennial streams. This would not reduce 

shading on fish-bearing streams or non-fish bearing perennial streams. Shade was not a 

consideration along intermittent streams since they should not affect peak water temperatures; 

however, some shade would be maintained in Class IV RHCAs to contribute toward meeting 

RMOs. Precommercial thinning would not reduce shade on streams, including 303(d) listed 

streams, based on monitoring that showed this activity resulted in a change of less than one (1) 

percent (Fontaine 1998). There is a risk of conifer thinning in aspen and cottonwood stands 

reducing shade for a short time (up to 6 months); however, water temperatures would still meet 

state standards.

foot buffer. Approximately 36 percent of the RHCAs on fish-bearing streams and 33 percent on 

perennial non-fish bearing streams are in units with prescribed fire. It is estimated that between 

20 percent of the area in the RHCA would burn with most of this being at low intensity and 

further away from the stream. There should not be any measurable increase in water

Alternative 4 

There would be about 127 acres of commercial harvest in Class I, II, and III RHCAs. This 

would not reduce shading on fish-bearing streams or non-fish-bearing perennial streams. The 

only commercial harvest within an RHCA on a 303(d) listed stream is in Unit 841 along Marks 

Creek. Commercial harvest in this unit would be accomplished using a helicopter logging 

system. Commercial harvest would only occur in the outer 100 feet of the 300-foot RHCA and 

would not reduce shade on Marks Creek. 

There will be about 675 acres of precommercial thinning in Class I, II, and III RHCAs. In the 

Hamilton Creek RHCA, precommercial thinning would occur in Units 708 and 873. In the Little 

Hay Creek RHCA, thinning would occur in Unit 402 which is an aspen unit. In the Marks Creek 

RHCA, precommercial thinning would occur in Units 505, 567, 840, and 841, and hardwood

There would be about 94 acres of commercial harvest in Class I, II, and III RHCAs. This would 

not reduce shading on fish-bearing streams or non-fish-bearing perennial streams. The only 

commercial harvest within an RHCA on a 303(d) listed stream is in Unit 841 along Marks Creek. 

Commercial harvest in this unit would be accomplished using a helicopter logging system. 

Commercial harvest would only occur in the outer 100 feet of the 300-foot RHCA and would not

away from the stream. There would not be any measurable increase in water temperatures on 

perennial streams. There is a potential to increase water temperature in intermittent non-fish

Cumulative Effects 

The Hash Rock Fire in 2000 resulted in measurable increases in water temperature in Hamilton 

and McGinnis Creeks and may have resulted in increases in Cornez and Reilly Creeks. Shade 

should have recovered in low-intensity burn areas, but it may take up to 20 years to fully recover 

in the high-intensity burn areas. Monitoring on Hamilton and McGinnis Creeks show water 

temperatures returned to below threshold values in 2003. The streams in the Upper Marks Creek 

subwatershed on the northwest side of U.S. Highway 26 are below the state water temperature 

standard threshold. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 166 

Past logging, road construction, and grazing have reduced shading in the project area. This has 

been offset in some drainages by increased shading from dense overstocked stands of conifers. 

No reduction of shading on fish bearing and perennial non-fish-bearing streams is expected as a 

result of the proposed timber harvest or precommercial thinning based on design criteria. 

Possible short term reductions in shade resulting from conifer thinning in aspen and cottonwood 

stands and prescribed fire are not expected to produce any measurable increases in temperature. 

Past deciduous riparian plantings outside of exclosures in Crystal and Little Hay Creeks are 

being heavily browsed by livestock and wildlife. The allotment management plans for the 

Crystal Springs and Burn Allotment will be analyzed over the next 2 years with the Marks Creek 

and Wildcat Allotments scheduled to start in 2009. The updates to these allotments will not be 

completed until after the decision is made on the Spears Project. It is reasonably foreseeable that 

changes in livestock grazing will result in improved channel condition because of activities such 

as moving water troughs out of riparian zones, fencing or enlarging exclosures at spring source 

areas of water developments, and developing more water sources in the uplands. Changing 

livestock management is outside the scope of this document; however, it is reasonably 

foreseeable that there will be an improvement in riparian condition due to changes in the range 

utilization standards in the Grazing Implementation Monitoring Module (IIT 2000). Studies in 

the intermountain region (Clary 1999) indicate that the height of grasses and forbs that are to be 

left in key riparian areas indicate a level of grazing that allows a corresponding recovery of 

palatable woody vegetation. Bank stability and channel geometry interact with vegetation but 

may respond differently, depending on the extent of continued mechanical disturbance in the 

channel and the current channel condition. 

None of the alternatives are expected to produce measurable increases in the maximum water 

temperature. All alternatives meet state and INFISH water quality temperature standards. State 

Water Quality Rules also indicated that recurring activities, including rotating grazing pastures, 

are not to be considered new or increased discharges which would trigger an anti-degradation 

review as long as they do not increase in frequency, intensity, duration, or geographic extent 

(OAR 340-041-0004(4)(a)). 

There are no reasonably foreseeable activities that would affect stream shade. 

Sediment and Turbidity 

Affected Environment 

It is estimated that between 60 and 75 percent of the sediment in the streams in the Marks Creek 

Watershed and Veazie Creek Subwatershed is coming from in-channel erosion such as bank 

erosion, head cuts, and channel scour. Channel destabilization can result from changes in peak 

flows, sediment load, roads, and livestock impacts. Potential increases from in-channel sources 

resulting from harvest and natural disturbance induced increases in runoff are analyzed by the 

Equivalent Harvest Area (EHA) model. 

In the late summer of 2000, the Hash Rock Fire burned approximately 4,594 acres in the Marks 

Creek Watershed, predominately in the Mill Creek Wilderness. Turbidity and suspended 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 167 

sediment samples were collected in Marks Creek above the Little Hay Bridge between 1998 and 

2005. Samples collected since the fire were compared to samples collected prior to the Hash 

Rock Fire to see if projected increases occurred. Because of the low snow pack and lack of 

severe rainstorms the first few years after the fire, erosion, and sediment delivery to streams was 

less than expected. Peak flows were also substantially less than average. Analysis indicates that 

turbidity in 2001 and 2002 was higher than in samples prior to the fire with that in 2002 being 

lower than that in 2001. However, when the post-fire turbidity for Marks Creek was compared 

with that from Ochoco Creek, which was not affected by the fire, the ratio was found to be 

within the normal range of fluctuation that existed prior to the fire. Dredging in Marks Pond by 

home owners in the spring of 2002 appears to have affected some water quality samples. 

Adequate moisture in the spring and summer of 2001 and the spring of 2002 allowed substantial 

recovery of grasses and forbs in the low to moderate-intensity burn areas and some high-intensity 

burn areas. Needle fall in the high-intensity burn areas without crown fire also continued to 

increase effective ground cover. This combined with the lack of rilling during the first 2 years 

after the fire reduced the risk of higher sediment rates during the remainder of the recovery. 

While the Hash Rock Fire is still affecting flows in the most severely burned drainages, surface 

erosion has returned to pre-fire levels. Fire lines were hydrologically closed and seeded in 2000 

and should also have recovered. There is still a risk of sediment delivery from landslides 

occurring in the high-intensity burn areas on dormant landslide terrain, especially in Hamilton 

Creek, the West Fork Cornez Creek, and McGinnis Creek. Total reinforcement from live and 

dead roots reaches the low point 7 years after the fire (2007) and recovers as live root 

reinforcement increases (Ziemer 1981). These landslides should be fairly small and localized 

due to the drier climate in the project area. 

State water quality standards direct that turbidity levels should not exceed background levels by 

more than 10 percent. The Forest Plan indicates that this will be accomplished by maintaining 

stream bank stability and implementing Best Management Practices (BMPs). 

Turbidity is the degree to which suspended material in the water impedes light penetration. 

There is normally a close correlation between turbidity and suspended sediment in a given 

stream, but this correlation can change as organic material increases over the summer or if the 

percent of sediment from different sources in the drainage changes. Turbidity does not measure 

the amount of sediment being transported as bedload. 

From field observations, it can be seen that the further a sediment source is from a stream, the 

smaller the percentage that gets delivered to the channel. This is due to infiltration of the water 

carrying the sediment, deposition at slope breaks, and deposition in depressions, behind surface 

debris, and in vegetation. Delivery bands derived from Leven (1978) were used for this analysis. 

Sediment from the uplands, direct and cumulative effects to water quality from accelerated 

sediment delivery related to timber harvest practices, fire, and road construction and use were 

evaluated by comparing the relative erosion and sediment delivery rates of the alternatives based 

on the Relative Erosion Rate (RER) model. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 168 

The RER procedure evaluates sediment delivery. It evaluates direct changes to sediment load 

from current management practices and average rates that reflect previous practices and recovery 

rates. Only management activities within 600 feet of mapped streams are evaluated. Soil 

erosivity is based on the Forest Soil Resource Inventory; slopes are derived from the GIS Digital 

Elevation Model; delivery potential is calculated from a technique derived from PSWHA I 

(Leven 1978); and potential sediment yield and recovery are calculated using the “Guide for 

Producing Sediment Yield from Forested Watersheds” (Forest Service 1981), and WATSED 

(Forest Service 1992). Based on the low average annual precipitation in the project area, low 

volume per acre, and not operating in the rainy season, haul delivered sediment should be low 

(less than 10 percent of the road delivered sediment). Because of the amount and period of haul 

on individual roads, annual precipitation, and the low sediment delivery, haul delivered sediment 

was not calculated because of the low level. The RER does not calculate the actual sediment 

load but calculates a Relative Erosion Rate that is used to compare alternatives. 

The RER depicts potential sediment delivery based on the amount and type of ground 

disturbance, slope/erosion class (based on soil erosivity and slope), and distance to stream 

channels. The actual sediment delivery may be higher or lower than predicted depending on the 

amount of vegetative recovery before storm events and storm intensity. Elevated sediment 

delivery may occur even if no additional activities are accomplished if a large runoff event 

occurs such as that in January 1997. The first timber sale is to be offered in 2007. RER 

calculations assume all harvest activities, in Alternatives 2, 4, and 5, will take place between 

2008 and 2011. In the project area, a sixth of the harvest is assumed to occur in 2008, a third in 

2009 and 2010, and a sixth in 2011. Precommercial and hardwood thinning activities are 

assumed to be completed by 2013. Fuels treatments were modeled as being finished in 2015. 

Environmental Consequences 

Alternative 1 

Sediment and turbidity levels would not change. Over time, without disturbance, fuel loading in 

stands would continue to progress toward Condition Class 3, which has a higher risk of highintensity fire. In the long term, there is a potential for indirect effects associated with fuel 

loading that would carry high-intensity wildfire. If a large-scale, high-intensity fire was to occur,

there is a high probability of increased sediment delivery resulting in adverse effects to aquatic 

habitats. It is difficult to predict the time or the scale and intensity at which such an event might

occur, but it is highly probable that it would be larger and more intense than what happened 

historically due to increased ladder fuels and higher fuel loadings. Roads in the stream influence 

zone would not be inactivated (closed) or decommissioned. 

Alternative 2 

Alternative 2 proposes harvest on 16.7 percent of the project area (14.4% tractor, 0.2% skyline, 

and 2.1% helicopter). It is estimated that 90 percent of the sediment delivered to streams from 

surface erosion comes from within 400 feet of the channel. This alternative proposes harvest on 

approximately 11.3 percent (1,421 acres) of total NFS lands in the project area within 400 feet of 

streams (8.3% tractor, 0.3% skyline, and 2.7% helicopter). Approximately 1,051 acres of tractor 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 169 

harvest, 38 acres of skyline harvest, and 332 acres of helicopter harvest are proposed within 400 

feet of streams. Megahan (1980) found that tractor harvest produced about 30 percent less 

sediment than clearcutting. Skyline harvest produces about half of that caused by tractor 

logging, and helicopter less than a fifth. Tractor harvest units within 200 feet of streams that 

have the highest potential sediment delivery are shown in Table 54. The RER analysis indicates 

that about 46 percent of the potential new sediment originates from timber harvest. It is 

estimated more than 25 percent of this logging generated sediment would come from five tractor 

harvest units: 108, 139, 148, 163, and 776. Reshin et al. (2006) in a study with samples in both 

eastern and western Washington found that a 10-meter (32.8 foot) setback of felling and yarding 

activities prevented sediment delivery to streams from about 95 percent of harvest-related

erosion features and said a wider setback may be advisable on portions of units where steep inner 

gorges extend beyond 10 meters. Lynch et al. (1985) determined that a 30 meter (98.4 foot) 

buffer from logging operations removed an average of 75-80 percent of the suspended sediment 

in storm water. This is consistent with post-harvest observations by the project hydrologist on 

the Ochoco National Forest, but suspended sediment delivery appears to be lower because of the 

lower precipitation rates east of the Cascades and higher infiltration rates in the project area. 

This alternative includes underburn activities on 40 percent (5,047 acres) of the project area 

within 400 feet of streams. Planned ignitions are designed to produce a mosaic burn. About 20 

percent of the units within RHCAs are expected to burn. Burning would not be accomplished all 

at one time, but is expected to take up to 10 years to complete depending on when thinning 

activities occur and when suitable weather conditions for fire ignition occur. Commercial 

harvest and precommercial thinning would reduce ladder fuels and reduce the number of stands 

at high risk from insects and disease. Commercial harvest, precommercial thinning, and fuels 

treatments overlay about 50 percent of the forested plant associations in the project area. Fuels 

treatments would be accomplished on about 51 percent of the area in forested plant associations 

outside the Mill Creek Wilderness. The reduction of surface and ladder fuels would reduce the 

amount of area susceptible to high-intensity wildfire. About 2,937 acres of activities (harvest 

and PCT) and 2,111 acres of natural fuels treatments are proposed within 400 feet of streams. 

About 28 percent of the new potential sediment originates from fuels treatments. 

This alternative constructs 3.3 mile of road within 400 feet of streams (0.16 mi/mi2). New and 

reopened roads would be closed or decommissioned after use. Stream crossings are a major 

sediment delivery site. Under this alternative, there would be two crossings on Class II streams, 

four crossings on Class III streams, and 28 crossings on Class IV streams. Road construction 

would result in 10 new crossings, one on a Class II and the other nine on Class IV streams. They 

can concentrate runoff and transport sediment down ditch lines, down the surface of the road, 

and can generate sediment on the approaches and at the crossing. Several miles of road (7.3 

miles) within 400 feet of streams would be decommissioned after use. In addition, this 

alternative would close 3.9 miles of road within 400 feet of streams after completion of the sale. 

The RER analysis indicates that about 28 percent of the potential new sediment originates from 

roads. Most sediment delivered to streams would come from stream crossings, road drainage 

close to streams, and harvest and fuels treatments adjacent to Class IV streams. 

Field observation and monitoring of the Trout Creek timber sale and the Hash Rock Fire have 

shown that intact RHCAs are effective at filtering sediment. Design elements prevent 

mechanical disturbance of stream channels and generally preclude placing landings and using 

ground-based equipment in RHCAs (see Chapter 2 for exceptions). This alternative proposes 48 

acres or about 4 miles of tractor harvest in Class 4 RHCAs (Class IV streams) by pulling cable 

from outside the RHCA. Based on past monitoring, design elements to protect stream channels 

from mechanical disturbance and maintain filtering in fuels units, and delayed burning in 

RHCAs with precommercial thinning slash, this alternative has a moderate risk of sediment 

delivery, but would still meet state water quality turbidity standards because filtering vegetation 

would be maintained in RHCAs. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 171 

Alternative 3 

No timber harvest or road work is proposed in this alternative. All new potential sediment 

originates from fuels treatments. 

This alternative includes underburning activities on 37 percent (4,628 acres) of the project area 

within 400 feet of streams. Planned ignitions are designed to produce a mosaic burn. About 20 

percent of RHCAs are expected to burn. Burning would not be accomplished all at one time, but 

may take up to 10 years to complete. Precommercial thinning would reduce ladder fuels and 

reduce the number of stands at high risk from insects and disease. Precommercial thinning and 

fuels treatments overlay about 46 percent of the forested plant associations in the project area. 

Fuels treatments would be accomplished on about 47 percent of the area in forested plant 

associations outside the Mill Creek Wilderness. The reduction of surface and ladder fuels would 

reduce the amount of area susceptible to high-intensity wildfire. About 10 percent less new 

potential sediment originates from fuels treatments in this alternative than in Alternative 2. Most 

sediment delivered by this alternative to streams would come from fuels treatments adjacent to 

Class IV streams. The RER analysis indicates that Alternative 3 generates 74 percent less 

potential new sediment than Alternative 2. 

Based on the lack of mechanical disturbance in RHCAs and design elements to maintain 

filtration in RHCAs, Alternative 3 would meet state water quality turbidity standards. 

Alternative 4 

Alternative 4 proposes harvest on 13.4 percent of the project area (11.2% tractor and 2.2% 

helicopter). It is estimated that 90 percent of the sediment delivered to streams from surface 

erosion comes from within 400 feet of the channel. This alternative proposes harvest on 

approximately 9.6 percent (1,201 acres) of the NFS lands in the project area within 400 feet of 

streams (7.0% tractor & 2.6% helicopter). Approximately 879 acres of tractor harvest and 322 

acres of helicopter harvest are proposed within 400 feet of streams under this alternative. Tractor 

harvest units within 200 feet of streams that have higher potential sediment delivery are shown in 

Table 55. About 19 percent less new potential sediment originates from harvest treatments in 

this alternative than in Alternative 2. It is estimated more than 25 percent of logging generated 

sediment would come from four tractor harvest units: 108, 148, 163, and 776. 

This alternative proposes underburn activities on 40 percent (4,982 acres) of the project area 

within 400 feet of streams. Planned ignitions are designed to produce a mosaic burn. Only 

about 20 percent of the units within RHCAs are expected to burn. Burning would not be 

accomplished all at one time, but may take up to 10 years to complete. Commercial harvest and 

precommercial thinning would reduce ladder fuels and reduce the number of stands at high risk 

from insects and disease. Commercial harvest, precommercial thinning, and fuels treatments 

overlay about 49 percent of the forested plant associations in the project area. Fuels treatments 

would be accomplished on about 50 percent of the area in forested plant associations outside the 

Mill Creek Wilderness. The reduction of surface and ladder fuels would reduce the amount of 

area susceptible to high-intensity wildfire. New potential sediment originating from fuels 

treatments in this alternative are about the same as those in Alternative 2.

 There is no harvest in Class IV RHCAs in these units. 

This alternative constructs 1.3 mile of road within 400 feet of streams (0.07 mi/mi2). New and 

reopened roads would be closed ore decommissioned after use. Several miles of road (6.5 miles) 

within 400 feet of streams, would be decommissioned. In addition, 3.8 miles of road within 400 

feet of streams would be closed after completion of commercial timber harvest. Stream 

crossings are a major sediment delivery site. Under this alternative, there would be one crossing 

on a Class II stream, four crossings on Class III streams, and 23 crossings on Class IV streams. 

Road construction would result in five new crossings on Class IV streams. They can concentrate 

runoff and transport sediment down ditch lines, down the road surface, and can generate 

sediment on the approaches and at the crossing. About 62 percent less new potential sediment 

originates from roads in this alternative than in Alternative 2.

about 3 miles of tractor harvest in Class IV RHCAs by pulling cable from outside the RHCA. 

Based on past monitoring, design elements to protect stream channels from mechanical 

disturbance, maintain filtering in fuels units, and delayed burning in RHCAs with precommercial

Alternative 5 

Alternative 5 proposes harvest on 10.7 percent of the project area (8.9% tractor and 1.8% 

helicopter). This alternative proposes harvest on approximately 7.4 percent (931 acres) of the 

NFS lands in the project area within 400 feet of streams (5.5% tractor and 1.9% helicopter). 

Approximately 703 acres of tractor harvest and 228 acres of helicopter harvest are proposed 

within 400 feet of streams. Tractor harvest units within 200 feet of streams that have higher 

potential sediment delivery are shown in Table 56. The RER analysis indicates that this 

alternative generates 33 percent less potential new harvest generated sediment than Alternative 2. 

Three tractor units (108, 139, and 163) account for more than 20 percent of the projected harvest 

generated sediment delivery in Alternative 5. 

This alternative proposes underburn activities on 37 percent (4,685 acres) of the project area 

within 400 feet of streams. Planned ignitions are designed to produce a mosaic burn. About 20 

percent of the area within units in RHCAs are expected to burn. Burning would not be 

accomplished all at one time, but may take up to 10 years to complete. Commercial harvest and 

precommercial thinning would reduce ladder fuels and reduce the number of stands at high risk 

from insects and disease. Commercial harvest, precommercial thinning, and fuels treatments 

overlay about 47 percent of the forested plant associations in the project area. Fuels treatments 

would be accomplished on about 48 percent of the area in forested plant associations outside the 

Mill Creek Wilderness. The reduction of surface and ladder fuels would reduce the amount of 

area susceptible to high-intensity wildfire. About 7 percent less new potential sediment 

originates from fuels treatments in this alternative than in Alternative 2. 

This alternative constructs 1.3 mile of road within 400 feet of streams (0.07 mi/mi2). New and 

reopened roads would be closed or decommissioned after use. Nearly 6 miles of road within 400

within 400 feet of streams. Stream crossings are a major sediment delivery site. Under this 

alternative, there would be one crossing on a Class II stream, three crossings on Class III 

streams, and 21 crossings on Class IV streams. Road construction would result in six new 

crossings on Class IV streams. They can concentrate runoff and transport sediment down ditch

 There is no harvest in Class IV RHCAs in these units. 

Most sediment delivered to streams would come from stream crossings, road drainage close to

Field observation and monitoring of the Trout Creek Timber Sale and the Hash Rock Fire have

proposes 29 acres or about 2.4 miles of tractor harvest in Class IV RHCAs by pulling cable from 

outside the RHCA. Based on monitoring, design elements to protect stream channels from 

mechanical disturbance, maintain filtering in fuels units, and delayed burning in RHCAs with 

precommercial thinning slash, this alternative would meet state water quality turbidity standards. 
Chapter 3 - Affected Environment and Environmental Consequences

Reshin et al. (2006) in a study with samples in both eastern and western Washington found that a 

10-meter (32.8 foot) setback of felling and yarding activities prevented sediment delivery to 

streams from about 95 percent of harvest related erosion features and said a wider setback may 

be advisable on portions of units where steep inner gorges extend beyond 10 meters. Lynch et 

al. (1985) determined that a 30 meter (98.4 foot) buffer from logging operations removed an 

average of 75-80 percent of the suspended sediment in storm water. This is consistent with postharvest observations by the project hydrologist on the Ochoco National Forest, but suspended 

sediment delivery appears to be lower because of the lower precipitation rates east of the 

Cascades and higher infiltration rates in the project area. 

Cumulative Effects 

The Bottom Line Survey indicates that about 3 percent of the stream reaches in the project area 

have greater than 20 percent cutbank and about 17 percent have between 10 and 20 percent 

cutbank. Road alignment on U.S. Highway 26 has resulted in channelization of reaches 2, 3 and 

6 of Marks Creek. After the Hash Rock Fire, headcut work and riparian planting were completed 

on McGinnis Creek and undersized culverts were replaced on Hamilton, Cornez, Reilly, and 

McGinnis Creeks. Headcuts were treated in Little Hay Creek in 2001 and McGinnis Creek in 

2002 which reduced sediment delivery. Riparian planting and exclosure fencing were also 

accomplished on Little Hay Creek in 2002 and 2003. Headcuts were treated and channel 

restoration work accomplished in Marks Creek on private property below the National Forest 

boundary by the Crooked River Watershed Council between 2002 and 2005. Increases in flow 

and loss of stream bank vegetation due to high-intensity burn on the Hash Rock Fire may still be 

resulting in bank erosion and channel widening in the more severely impacted drainages 

impacted by the fire, especially in Hamilton Creek, the unnamed tributary to the west of 

Hamilton Creek, and the west fork of Cornez Creek. 

Ground disturbance associated with trails, off highway ehicle (OHV) use, dispersed recreation, 

and firewood gathering may cause localized sediment delivery but is small on a watershed scale 

and was not included in the analysis. Sediment from routine road maintenance, which is 

included in the model, was overestimated because the model assumes annual maintenance on 

open roads. It is estimated that most of management derived sediment delivered to streams by 

surface erosion on NFS lands in the project area is coming from roads. Open road densities 

within 400 feet of stream channels, the source area of an estimated 90 percent of surface 

sediment delivered sediment, are shown in Table 57. Proposed road closure and 

decommissioning would reduce the cumulative sediment delivery in the long run but ground 

disturbance from ripping and installing drainage structures would increase sediment the first year 

or two. 

While livestock can affect sediment delivery, in the Spears project area their primary impact 

appears to be on riparian vegetation and channel condition. Degraded channel conditions in the 

headwaters of many streams and in spring areas in the project area have resulted from livestock 

concentration. Changing livestock management is outside the scope of this document; however, 

it is reasonably foreseeable that cattle will continue grazing in the allotments. Special grazing 

restrictions implemented in the Viewpoint Pasture after the Hash Rock Fire were successful 

based on monitoring. These special grazing restrictions have been lifted. The allotment

management plans for the Crystal Springs and Burn Allotments will be analyzed over the next 2 

years, with the Marks Creek and Wildcat Allotments scheduled to start in 2009. The updates to 

these allotments will not be completed until after the decision is made on the Spears project area. 

It is reasonably foreseeable that changes will result in improved channel condition. Upward 

trends in riparian condition are expected to continue due to changes in the range utilization 

standards in the Grazing Implementation Monitoring Module (IIT 2000). These utilization 

standards are used to determine when livestock are to be removed from pastures. Studies in the 

intermountain region (Clary 1999) indicate that the height of grasses and forbs that are to be left 

in key riparian areas indicate a level of grazing that allows a corresponding recovery of palatable 

woody vegetation. Bank stability and channel geometry interact with vegetation but may 

respond differently, depending on the extent of continued mechanical disturbance in the channel 

and the current channel condition. State Water Quality Rules indicated that recurring activities, 

including rotating grazing pastures, are not to be considered new or increasing discharges which 

would trigger an anti degradation review as long as they do not increase in frequency, intensity, 

duration, or geographic extent (OAR 340-041-0004(4)(a)). 

Equivalent Harvest Area (EHA) 

Affected Environment 

Peak annual flows resulting from snowmelt normally occur in March through April in the project 

area. However, peak annual flows resulting from rain-on-snow events in early winter have 

produced some of the highest flows in the project area over the last 50 years. High flows can 

result from intensive convective thunderstorms that cause flash floods during the spring and 

summer. Flash flooding is not a major factor in the Marks Creek Watershed due to vegetation, 

ground cover, and the buffering affect of the forest canopy. Peak flows are probably earlier and 

higher than historically due to loss of floodplain storage due to entrenched channels and soil loss, 

compaction, timber harvest, and road construction which cause flashier responses. This has been 

offset somewhat by increased understory canopy cover. 

The Hash Rock Fire burned approximately 4,594 acres in the Marks Creek Watershed in 2000. 

More than half of this was low intensity resulting in less than 10 percent mortality. Since at least 

15 percent of the canopy needs to be removed to increase water yield, the primary effect from the 

fire should result from the 4.2 percent of the watershed that burned at moderate to high intensity 

with most of this coming from the 2.7 percent that burned at high intensity. Less than 1 percent 

of the watershed had crown fire. The fire occurred above 4,500 feet primarily in the Mill Creek 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 177 

Wilderness on steeper ground. Due to the elevation of the area that burned, there was only a 

small effect on peak flows resulting from rain-on-snow events in early winter. The fire affected 

peak flows associated with spring snow melt but, due to the small increase in EHA from the fire, 

are only observable in those drainages directly affected by it. Increased peak flows in Hamilton 

Creek, the unnamed tributary to the west, and the west fork of Cornez Creek, the most severely 

affected drainages, are expected to last for at least 25 to 30 years. Peak flow increases in the 

other drainages directly affected by the fire should be within the normal range of variability. 

Base flows were probably higher prior to alterations which have occurred over the last 100 years. 

Stream entrenchment has reduced storage potential in alluvial aquifers. Upland storage has been 

lost due to road construction, erosion, and compaction. Prior to European settlement, frequent 

fires maintained lower evapotranspiration and interception rates and water storage in wetlands 

and beaver ponds contributed to base flows. Increases in base flow due to removing trees tend to 

be short term (5 to 10 years) and return to pre-disturbance levels as other vegetation utilizes the 

increase. 

The Hash Rock Fire caused increases in base flows in the drainages directly affected by the fire. 

The increases are most pronounced in Hamilton Creek and the next tributary to the west and to a 

lesser extent in the west fork of Cornez Creek, and upper McGinnis Creek. Increases in Reilly 

Creek, Buck Creek and the main stem of Marks Creek were small and within normal annual 

fluctuations. Increases in the base flow are expected to last for 15 to 20 years after tree reestablishment in high-intenstiy burn areas. 

Stream surveys have identified a number of headcuts on tributaries to Marks Creek in the project 

area making these streams susceptible to increased flows. Headcuts were treated and channel 

restoration work accomplished in Marks Creek on private property below the National Forest 

boundary by the Crooked River Watershed Council between 2002 and 2005. The Forest Service 

accomplished headcut work and riparian planting on McGinnis Creek and replaced undersized 

culverts on Hamilton, Cornez, Reilly, and McGinnis Creeks following the Hash Rock Fire. 

Headcut repair, riparian planting, and exclosure fencing were accomplished on Little Hay Creek 

in 2002 and 2003. 

EHA is used to evaluate the risk to water quality and stream bank stability. The Forest Plan 

assigned an EHA threshold of 30 percent to the Marks Creek and Lower Ochoco Creek 

Watersheds (Veazie Creek Subwatershed). The Marks Creek Watershed Analysis (1998) 

recommended the EHA be reduced to 25 percent based on watershed condition and sensitivity. 

The EHA threshold should not be interpreted as a point above which detrimental impacts will 

occur but as a point above which detrimental impacts may occur, should a 10-year or greater 

storm or melt event take place (Anderson 1989). 

The February 12, 2007, Spears Vegetation Project Hydrology Report contains additional 

information on EHA. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 178 

Environmental Consequences 

EHA calculations assume all harvest activities in Alternatives 2, 4, and 5, will take place 

between 2008 and 2011. Within the project area, a sixth of the harvest is assumed to occur in 

2008, a third in 2009 and 2010, and a sixth in 2011. Precommercial and hardwood thinning 

activities would be completed by 2013. The analysis assumed that fuels reduction activities do 

not remove enough canopy to produce a measurable increase in water yield. Table 58 shows the 

expected EHA values from 2007 through 2015. 

Alternative 1 

There would be no direct effects from this alternative. EHA would continue to recover from past 

harvest and the Hash Rock Fire. Increased peak flows in Hamilton Creek, the unnamed tributary 

to the west, and the west fork of Cornez Creek, the drainages most severely affected by the Hash 

Rock Fire, would persist for several years. Table 58 displays the expected EHA values over 

time. 

The majority of the project area is in Fire Regimes I and III, and fuel loadings have moved into 

Condition Classes 2 and 3. Over time, without disturbance, fuel loading would continue the 

progression toward Condition Class 3, which has the highest risk of high-intensity fire. In the 

long term, there is potential for indirect effects associated with fuel loading that would carry a 

high-intensity wildfire. If a large-scale, high-intensity fire did occur, there would be an increase 

in EHA commensurate with the size and intensity of the fire. It is difficult to predict the time, or 

the scale and intensity at which such an event might occur, but it is probable that it would be 

larger and more intense than what happened historically due to increased ladder fuels and higher 

fuel loadings. 

Effects common to Alternatives 2, 3, 4, and 5 

The EHA would continue to recover from past harvest and the Hash Rock Fire. Increased peak 

flows in Hamilton Creek, the unnamed tributary to the west, and the west fork of Cornez Creek 

would persist during the period covered by this analysis. Timber harvest and precommercial 

thinning in the action alternatives would reduce interception and evapotranspiration, increase 

snow accumulation, and change snow melt rate and timing. The percentage of commercial 

timber harvest ranges from 16.7 percent of the project area in Alternative 2, to 13.4 percent in 

Alternative 4, to 10.7 percent in Alternative 5. There is no commercial harvest in Alternative 3. 

Fire would reduce interception by burning fuels and vegetation; reduce evapotranspiration by 

killing or burning back grasses, shrubs and small trees; and change the timing and rate of 

snowmelt. These increases would be partially offset by an increased uptake of water by the 

remaining trees and vegetation. The reduction in interception and evapotranspiration and rate of 

snow melt resulting from prescribed spring and fall burning should not result in any measurable 

increase in flows from areas being treated due to the low intensity of the burn. 

The 196 acres of thinning activities to improve cottonwood and aspen would help improve bank 

stability in stands adjacent to streams in the long term (starting within 5 to 10 years). 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 179 

The EHA model does not measure direct effects but is based on the principal that reduced 

canopy closure would reduce interception and evapotranspiration and would increase snow 

accumulation. Standing dead trees no longer transpire but still would affect interception and 

snow accumulation. In addition based on the aspect and elevation of the project area, reducing 

stand density would accelerate snowmelt. Restated, there would be more snow pack and it 

probably would come off faster. However, the EHA values for all of the alternatives are below 

the Forest Plan threshold of 30 percent and the recommended threshold of 25 percent in the 

watershed analysis. 

The probability of an event (flood) occurring can be increased by increasing the runoff efficiency 

of a drainage by road construction, increasing the snow pack through unit size and distribution, 

increasing snow melt rate by reducing canopy closure, or increasing the amount of water 

available by removing vegetation. Measurable increases in flow should start showing up when 

the EHA reaches about 20 percent (Hibbert 1965) and should be roughly proportional to the 

percentage of the area above that value. None of the alternatives would have a measurable 

increase on stream flows because the EHA value is below 20 percent in all alternatives.

Alternative 2 

Commercial harvest and precommercial thinning would reduce ladder fuels and reduce the 

number of stands at high risk from insects and disease. Commercial harvest, precommercial 

thinning, and fuels treatments overlay about 50 percent of the forested plant associations in the 

project area. Fuels treatments would be accomplished on about 51 percent of the area in forested 

plant associations outside the Mill Creek Wilderness. 

The EHA is below the Forest Plan threshold of 30 percent and the recommended threshold of 25 

percent in the watershed analysis. Harvest and precommercial thinning under Alternative 2 

would not produce any measurable increases in flow (EHA < 20%) in the Marks Creek 

Watershed or the Upper Marks, Lower Marks, and Veazie Creek Subwatersheds. 

Alternative 3 

Precommercial thinning would reduce ladder fuels and reduce the number of stands at high risk 

from insects and disease. Precommercial thinning and fuels treatments overlay about 46 percent 

of the forested plant associations in the project area. Fuels treatments would be accomplished on 

about 47 percent of the area in forested plant associations outside the Mill Creek Wilderness. 

Precommercial thinning proposed under Alternative 3 would not result in measurable increases 

in flow in the Marks Creek Watershed or the Upper Marks, Lower Marks, and Veazie Creek 

Subwatersheds. 

Alternative 4 

Commercial treatments and precommercial thinning would reduce ladder fuels and reduce the 

number of stands at high risk from insects and disease. Commercial harvest, precommercial 

thinning, and fuels treatments overlay about 49 percent of the forested plant associations in the 

project area. Fuels treatments would be accomplished on about 50 percent of the area in forested 

plant associations outside the Mill Creek Wilderness. 

The EHA is below the Forest Plan threshold of 30 percent and the recommended threshold of 25 

percent in the watershed analysis. Harvest and precommercial thinning under Alternative 4 

would not produce any measurable increases in flow (EHA < 20%) in the Marks Creek 

Watershed or the Upper Marks, Lower Marks, and Veazie Creek Subwatersheds. 

Alternative 5 

Commercial harvest and precommercial thinning would reduce ladder fuels and reduce the 

number of stands at high risk from insects and disease. Commercial harvest, precommercial 

thinning, and fuels treatments overlay about 47 percent of the forested plant associations in the 

project area. Fuels treatments would be accomplished on about 48 percent of the area in forest 

plant associations outside the Mill Creek Wilderness.

The EHA is below the Forest Plan threshold of 30 percent and the recommended threshold of 25 

percent in the watershed analysis. Harvest and precommercial thinning under Alternative 5 

would not produce any measurable increases in flow (EHA < 20%) in the Marks Creek 

Watershed or the Upper Marks, Lower Marks, and Veazie Creek Subwatersheds. 

Cumulative Effects 

The level of mortality due to the Hash Rock Fire is not expected to produce a measurable effect 

on peak flows at the watershed or subwatershed level, but it is expected to still be affecting flows 

in Hamilton Creek, the unnamed tributary to the west, and the west fork of Cornez Creek. Flows 

in Buck Creek, the east fork and main stem of Cornez Creek, Reilly Creek, and McGinnis Creek 

are within the normal range of variability. 

The EHA model evaluated water yield effects of past and proposed harvest, precommercial 

thinning, and underburning in the project area. It is estimated that about 90 percent of the 

forested land outside the wilderness and research natural area has been at least lightly harvested 

in the past. The model evaluated all timber harvest over the last 30 years plus the Marks Creek 

Fire (1968) and the Hash Rock Fire (2000). Overstory removal and regeneration harvest prior to 

the last 30 years is still affecting water yield, but has substantially recovered. Roads can reduce 

canopy and leaf area index but the area is small. The Forest Plan maximum recommended open 

road density of 3 miles per square mile results in less than a 1 percent EHA. This is less than the 

accuracy of the model and if roads were included only sections that were in forested plant 

associations may be evaluated. The primary effect of roads is increased runoff efficiency 

resulting from extension of the drainage system and erosion from the road surface and cut and 

fill slopes. Natural fuels underburning primarily kills seedlings and saplings and without 

connected precommercial thinning, does not remove enough of the canopy to affect the EHA. 

Insect, disease, and wind throw can reduce canopy but the concentration and area impacted are 

small and dispersed in the project and were not included in the model. The number and spacing 

of the downed trees removed in Pickup Salvage (2001) and beetle kill trees removed in Cougar 

Salvage and TC Salvage (2006) were so few and far apart that they did not affect EHA. Other 

management activities that remove trees that should not affect EHA are: removing safety trees 

from developed campgrounds, removing safety trees adjacent to system roads, removing conifers 

from aspen stands, juniper thinning in low precipitation zones, and the Christmas tree program. 

Harvest treatments on private lands below the National Forest boundary have been similar to 

those on the National Forest. There is currently no logging occurring on private lands in the 

project area. Based on species composition and past harvest activities, any future logging on 

private lands would probably be selective harvest. Since private land only accounts for about 5 

percent of the area in the project area, potential future timber harvest on private lands would 

have a minimal affect on water yield in the project area. 

Livestock grazing is not expected to affect peak or base flows. Livestock have little effect on 

EHA; their primary influence is on bank conditions which is one of the factors that determine 

what the channel response will be to changes in flow. Upward trends in riparian condition are 

expected to continue due to changes in the range utilization standards in the Grazing 

Implementation Monitoring Module (IIT 2000).

Wildlife 

Goshawk 

Affected Environment 

Goshawks utilize a variety of forest conditions within their territories, but tend to favor stands 

with patches of moderate to high overstory canopy closure, interlocking crowns, mature to old 

structure, presence of canopy gaps and flyways below the overstory, and proximity to water for 

nesting areas (Schommer and Silovsky 1994, Crocker-Bedford 1990, Bull and Hohmann 1992, 

Reich et al. 2004, and Reynolds et al. 1992). 

There are 22,896 acres of primary nesting habitat within the project area. This figure is based on 

the abundance of forested stands with medium to large size trees (size class 4 and 5) in all seral 

stages (E, M and L) in grand fir and Douglas-fir PAGs, and in the late seral (L) stage in 

ponderosa pine. There are six known goshawk territories within the project area. Each of these 

territories include a variety of habitats and forest conditions. Post-fledging areas (PFAs) have 

been mapped around or adjacent to known goshawk nesting sites. PFAs are generally mapped in 

the best available forested stands (moderate to high canopy closure with medium and large sized 

trees common) around or adjacent to known nest areas. Nesting sites are also mapped within 

each territory. There is one nest site mapped where all known alternate nests can be reasonably 

accommodated within one nest site. If alternate nests are in separate locations, then additional 

nest sites are mapped. In this project area, five of the PFAs are associated with a single mapped 

nest site and one is associated with two separate nest sites. The January 29, 2007, Spears 

Wildlife Report contains additional information on goshawk. 

Environmental Consequences 

Alternative 1 

This alternative would not treat forest stands within PFAs or 30-acre nest sites. This alternative 

would not result in modification of existing habitat conditions. It is estimated that the project 

area would retain habitat suitability in the short term, but potentially be exposed to subsequent 

long-term risk of high intensity disturbance and loss of overstory trees due to continued 

competition for moisture and the presence or development of ladder fuels over time. 

Alternative 1 would result in short-term retention of the existing amount and distribution of 

goshawk habitat at the landscape scale. There are 22,896 acres of primary nesting habitat within 

the project area. This alternative would also retain existing amounts and structural conditions 

within all six PFAs in the project area, at least in the short term. Goshawks are expected to 

continue to utilize the PFAs and other suitable habitat. 

Direct and Indirect Effects Common to Alternatives 2, 3, 4, and 5 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 183 

Acres outside the nest areas and within the PFAs that would be treated under any action 

alternative would be thinned from below. These activities are intended to improve forest 

condition by removing understory trees, with the result of enhancing longevity of dominant trees 

and growth of retained co-dominant trees. These activities would result in more open space for 

flight below the overstory canopy which would improve foraging habitat, but would reduce 

nesting and post-fledging hiding cover. All existing snags would be left that are not deemed to 

be a safety hazard. 

Precommercial thinning would be limited to small trees less than 12 inches dbh. However, the 

majority of trees to be cut during precommercial thinning would be less than 9 inches dbh. 

All action alternatives would implement underburning of natural fuels outside of thinning units 

within PFAs. This would occur in three PFAs, but the majority would be in the Crystal Springs 

PFA. Underburning activities within the PFAs would be designed to protect large overstory 

trees and, to the extent practical, snags and large down wood. However, it is predicted that snags 

and down wood that are in advanced stages of decay would be consumed by fire. This would be 

partially offset by the creation of snags and down wood due to fire-killed trees. However, the 

effect of fire on snag retention would likely result in a higher number of hard snags, with a 

concurrent reduction in soft and hollow snag habitat. Burning has the potential to remove large 

snags where they are present prior to treatment, while increasing the relative abundance of 

smaller snags that result from the fire. Prescribed burning would also stimulate production of 

herbaceous vegetation for several years after the fire, and shrubby vegetation 3-15 years after the 

fire. These changes in conditions would provide foraging habitat for some species that would be 

prey for goshawk (such as song birds), while potentially altering nesting habitat for some species 

(such as woodpeckers), which are also prey for goshawk. 

The amount of suitable primary nesting habitat for goshawks within the project area predicted to 

be present after implementation (based on seral structural stage and PAG) is displayed in Table 

59. The rate of development of future habitat can also be accelerated by thinning activities. 

Over time, as canopy closure recovers and trees in the stand attain diameter growth, primary 

nesting habitat would develop or be regained in treated areas, and would develop in other areas 

as well. All alternatives result in goshawk habitat remaining within the HRV both immediately 

after treatment and after 50 years of development post-treatment.

This alternative would commercially harvest timber on 421 acres and precommercial thin trees

outside of harvest units within PFAs on approximately 144 acres. No units are within 30-acre 

nest sites. This alternative would result in modification of existing habitat conditions on a total 

of 678 acres within PFAs. It is estimated that commercially harvested areas and a portion of 

underburned areas within PFAs would have a short-term reduction in habitat suitability, but 

potentially subsequent long-term improvement through overstory maintenance and reduced risk 

of high-intensity disturbance. The remainder of the treated area within PFAs (understory 

thinning and some underburned areas) would likely retain existing habitat suitability or may be 

improved through opening up of understory canopy conditions (more flight paths and improved 

prey visibility). Acres of treatment within each PFA are displayed in Table 60.

This alternative would result in a 376-acre net increase in the amount of goshawk habitat at the 

landscape scale after all activities are complete which would result in 23,272 acres of primary 

nesting habitat within the project area. This alternative would also accelerate the development of 

future habitat, based on forest development projections, leading to a 922-acre net increase in 50 

years compared to no action. This alternative would alter existing amounts and structural 

conditions within all six PFAs in the project area, on a total of 680 acres. Treatments would 

range from less than 1 percent to 47 percent of each PFA. Goshawks may be disturbed by 

activities outside of the nesting season or outside of seasonally restricted areas during operations. 

However, because (1) less than 50 percent of any PFA would be treated, (2) no activities would 

occur within known nest sites, (3) activities are limited to thinning from below and prescribed 

burning, and (4) seasonal restrictions would be applied during the nesting season, all PFAs are 

expected to remain suitable for occupancy by nesting goshawks and their young. 

Alternative 3 

This alternative would thin small trees on 265 acres in PFAs. Alternative 3 would implement 

underburning of natural fuels outside of thinning units within PFAs on approximately 234 acres. 

No activities are proposed within the 30-acre nest sites. This alternative would result in 

modification of existing habitat conditions on a total of 499 acres within PFAs. It is anticipated 

that this alternative would retain habitat suitability in the short term, with a long-term

This alternative would result in a 347-acre net increase in the amount of goshawk habitat at the 

landscape scale after all activities are complete which would result in 23,243 acres of primary 

nesting habitat within the project area. This alternative would also accelerate the development of 

future habitat, based on forest development projections, leading to a 978-acre net increase in 50 

years compared to no action. This alternative would alter existing amounts and structural 

conditions within all six PFAs in the project area, on a total of 499 acres. Activities would range 

from less than 1 percent to 47 percent of each PFA. Goshawks may be disturbed by activities 

outside of the nesting season or outside of seasonally restricted areas during operations. Because 

(1) less than 50 percent of any PFA would be treated, (2) no treatments would occur within

(4) seasonal restrictions would be applied during the nesting season, all PFAs are expected to 

remain suitable for occupancy by nesting goshawks and their young. 

Alternative 4 

This alternative would commercially harvest timber on 245 acres and precommercially thin 

young trees on 218 acres in PFAs. Alternative 4 would implement underburning of natural fuels 

outside of thinning units within PFAs on approximately 144 acres. No units are within the 30-

landscape scale after all activities are complete which would result in 23,243 acres of primary 

nesting habitat within the project area. This alternative would also accelerate the development of 

future habitat, based on forest development projections, leading to a 956-acre net increase in 50 

years compared to no action. This alternative would alter existing amounts and structural

seasonal restrictions would be applied during the nesting season, all PFAs are expected to remain 

suitable for occupancy by nesting goshawks and their young. 

Alternative 5 

This alternative would commercially harvest timber on 111 acres and precommercial thin young 

trees on 326 acres in PFAs. A few harvest units overlap mapped PFAs: 306 and 858 in the 

Little Hay Creek PFA and 302 and 303 in the Claypool Spring PFA. Within these areas, harvest 

would retain clumpy distribution of dominant and co-dominant trees and variable thinning 

density in the understory, with the intent of promoting horizontal diversity in the stand and a 

high degree of interlocking crown structure as described in Management Recommendation for 

the Northern Goshawk in the Southwestern United States (Reynolds et al. 1992). Alternative 5 

would implement underburning of natural fuels outside of harvest units within PFAs on 

approximately 215 acres. No units are within 30-acre nest sites. This alternative would result in 

modification of existing habitat conditions on a total of 652 acres within PFAs. It is anticipated 

that the modified prescription included in this alternative would retain habitat suitability in the 

short-term, with a long-term improvement through overstory maintenance and reduced risk of

This alternative would result in a 454-acre net increase in the amount of goshawk habitat at the 

landscape scale post-treatment, 23,350 acres of primary nesting habitat within the project area. 

This alternative would also accelerate the development of future habitat, based on projections, 

leading to a 979-acre net increase in 50 years compared to no action. This alternative would alter 

existing amounts and structural conditions within all six PFAs in the project area, on a total of 

652 acres. Activities would range from less than 1 percent to 47 percent of each PFA. 

Goshawks may be disturbed by activities outside of the nesting season or outside of seasonally 

restricted areas during operations. Because (1) less than 50 percent of any PFA would be treated, 

(2) no activities would occur within known nest sites, (3) activities are limited to thinning from 

below and prescribed burning, (4) seasonal restrictions would be applied during the nesting 

season, and (5) the prescription includes measures to promote stand diversity, all PFAs are 

expected to remain suitable for occupancy by nesting goshawks and their young. 

Cumulative Effects 

Past harvest activities have occurred on 7,563 acres in the project area in the last 30-35 years. 

The majority of these harvest activities removed most or all of the overstory trees and goshawk 

habitat. These harvest activities occurred on approximately 3,260 acres in Lower Marks Creek, 

2,800 acres in Upper Marks Creek, and 7 acres in Veazie Creek. Some of these areas received 

harvest prescriptions that retained varied levels of abundance of large overstory trees. 

Prescriptions that retain approximately four to six live overstory trees would provide for some 

future large snag and log habitat as the younger stand develops into a mature stand, but would 

have largely eliminated goshawk habitat in the short term. These activities occurred on 

approximately 220 acres in Lower Marks Creek and 300 acres in Upper Marks Creek. 

Shelterwood harvests generally did not retain enough overstory trees to provide goshawk habitat 

in the short term. However, such stands do retain structure that may contribute to both the 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 188 

overstory and the snag and down wood components in the future as the stand develops around 

them. Shelterwood harvests occurred on approximately 260 acres in Lower Marks Creek and 

560 acres in Upper Marks Creek. Thinning, which has occurred on approximately 150 acres in 

the project area would have retained a portion of the overstory and may remain suitable for 

goshawks after treatment depending on residual canopy closure and stand structural diversity. 

The Hash Rock Fire burned approximately 4,594 acres in the Marks Creek Watershed, removing 

foraging and PFA habitat within one goshawk territory (Reilly Creek PFA 9903). The PFA has 

been remapped to include the best available remaining habitat around the nest and historic use 

area. Riparian planting and aspen restoration that has been completed in the project area has 

improved habitat by enhancing habitat for prey (primarily birds), or is likely to contribute to 

improved habitat conditions in the future. At the same time, continued utilization by both big 

game and livestock have likely impacted the development of riparian hardwood habitat and 

habitat for shrub-nesting birds, which may provide prey for goshawks. The removal of snags for 

firewood, for hazard abatement, or under salvage sales (e.g. Cougar Salvage) may have reduced 

habitat for woodpeckers, which also represent prey for goshawks. Road closures that have been 

implemented have reduced the likelihood of snag removal and disturbance to nesting goshawks, 

though continued uncontrolled recreational use by off highway vehicles (OHV) has likely 

contributed to disturbance at one known nest site. Though past management activities have 

altered the amount, quality, and distribution of suitable goshawk habitat, or habitat components 

that contribute to habitat for their prey, the amount of reproductive habitat available to goshawks 

at the landscape scale is within the HRV as shown in Table 59. 

Ongoing and reasonably foreseeable activities would continue to interact with goshawks and 

their habitat as described above. Ongoing firewood cutting, grazing, recreational use, riparian 

improvement and exclosure maintenance activities are not expected to result in altering habitat 

suitability. All six known PFAs are expected to remain suitable for occupancy by nesting 

goshawks and their young. 

Management Indicator Species 

The Forest Plan identified Management Indicator Species (MIS) to determine the effects of 

management activities on fish and wildlife habitat. Management indicator species are species 

whose presence in a certain location or situation at a given population level indicates a particular 

environmental condition. Population changes are believed to indicate effects of management 

activities on a number of other species. 

Pileated woodpecker was identified as an indicator for species that require mature forest and oldgrowth habitat. Primary cavity excavators and the common (northern) flicker were identified to 

represent species that utilize snags and old-growth juniper habitat. 

Pileated Woodpecker 

Affected Environment 

Pileated woodpeckers are an indicator species for dense and more mesic late and old structure 

(LOS) forests. They typically select for multi-strata mixed conifer LOS. LOS stands described 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 189 

in relation to wildlife habitat include forest stands that are at least 5 acres in size and that contain 

sufficient numbers of large trees and total stand density to meet established criteria used to 

describe LOS forest habitat. There are two patch size criteria which are relevant to analysis of 

wildlife habitat. The 5-acre minimum patch size distinguishes groups of large trees of sufficient 

size to provide a LOS forested habitat patch. When LOS stands are described in this document, 

it refers to areas that were determined to meet or exceed the 5-acre patch size, based on nearest 

neighbor analysis in GIS. The other relevant patch size is 100 acres, which responds to LOS 

forest habitat emphasis in the Eastside Screens and triggers the identification of connective 

corridor described in the connective corridor section of this document. The previous section on 

LOS applies to analysis for HRV comparison, and looks at large trees within pixels (1/6 acre), 

regardless of stand size. The acres of LOS stands described in the wildlife section refer to 

treatments within forested environments a minimum of 5 acres in size and meeting the following 

criteria for large tree abundance (trees per acre greater than or equal to 21 inches dbh) and total 

stand density (basal area in square feet per acre): grand fir at least 15 trees per acre, and 60 

square feet of basal area; Douglas-fir at least 12 trees per acre and 40 square feet of basal area; 

mesic pine at least 10 trees per acre and 40 square feet of basal area; xeric pine at least 10 trees 

per acre and 30 square feet of basal area; juniper woodland at least 5 trees per acre and 12 square 

feet of basal area. 

Pileated woodpecker habitat associates prefer dense forest conditions; they include Townsend’s 

warbler, hermit thrush, and red-breasted nuthatch. As dense mixed-conifer stands often contain a 

high density of dead or dying trees, habitat for this species also represents habitat for the blackbacked woodpecker, which is attracted to stands with abundant snags and activity by bark beetles 

and wood boring beetles. The best pileated feeding habitat is within stands dominated by large 

(>20 inch dbh) fir. Current conditions in the project area favor the pileated woodpecker, with 

multi-strata late and old structure forests being within or above the historical range of variability 

in moist and dry grand-fir, and Douglas-fir PAGs. The existing condition for pileated 

woodpecker reproductive habitat within the project area is within the HRV as shown in Table 65. 

Forest Plan designated Old Growth Management Areas (OGMAs) are generally to provide 

reproductive habitat areas, and pileated feeding habitat has been mapped outside of the 

designated old growth. There are three OGMAs in the project area. Two of these have feeding 

habitat designated around them. Though the Jim Elliot Creek OGMA is within 2 miles of the 

Hash Rock Fire perimeter, the fire did not affect the areas designated for management of pileated 

woodpeckers. The third is contained within the Research Natural Area, which provides 

sufficient feeding habitat (exceeds the minimum requirements specified in the Forest Plan) for 

pileated woodpeckers. The pileated woodpecker prefers closed canopy, late to old growth firdominated habitat. They prefer stands with old growth, grand fir, abundant snags, abundant 

down logs, and canopy closure of at least 60 percent. Pileated woodpeckers use other species in 

proportion to their availability as foraging substrate. They use snags of ponderosa pine, 

Douglas-fir, and western larch, and snags at least 15 inches dbh were preferred for foraging. 

Pileated woodpeckers forage on down logs, but avoid lodgepole pine. These birds have been 

observed to glean insects from live Douglas-fir and grand fir in June and July (late instar 

budworms) and from live western larch from November to January (carpenter ants). Pileated 

woodpeckers select large, live, grand fir trees for night roosting, though they will use live larch 

and snags of ponderosa pine, grand fir, and larch (average 28 inches dbh). Hollow interiors of

trees or snags resulting from decay rather than excavation, and the presence of Indian paint 

fungus conks are prevalent in roost trees (Bull et al. 1992). Breeding bird survey data show no 

significant change in population for this species in the western states (Marshall et al. 1997). 

Within the project area, evidence of foraging by pileated woodpeckers has been observed on 

recently dead grand fir and potential roost holes were noted in large diameter, dead topped grand 

fir trees. Probable nest entrances have been observed in large diameter pine snags. The January 

29, 2007, Spears Wildlife Report includes more information on pileated woodpecker. 

Environmental Consequences 

Alternative 1 

This alternative would not treat LOS stands or forest stands within pileated feeding habitat or 

OGMAs. This alternative would maintain the existing acres of fir-dominated understory and 

canopy closure, at least in the short term. Of the approximately 1,400 acres of LOS stands that 

have been identified in the project area, 34 percent is in moist grand fir or Douglas-fir PAGs. 

These relatively more mesic areas are the most likely sites to sustain multi-strata LOS stands in 

the long term. Lack of treatment of the understory in these stands would perpetuate development 

of fir understory conditions which would increase pileated woodpecker habitat abundance and 

quality in the short term. Overtime, however, high stand densities may lead to mortality due to 

insects, disease, or high-intensity fire. The effect of such disturbances on pileated woodpecker 

habitat in the long term is dependent on the type, severity, and extent of the event(s). Extensive 

areas of high mortality that may potentially result from future, large-scale disturbance which 

would likely limit the amount of suitable nesting habitat in affected areas, whereas events 

resulting in mosaics including moderate and low intensity disturbance may continue to provide 

nesting habitat over time. 

This alternative would maintain the suitability of existing habitat for pileated woodpeckers in the 

short term. Over time, the suitability for nesting is expected to decline on sites that cannot 

sustain high densities of conifers. As trees on such sites succumb to insect invasion they would 

provide a foraging substrate for a variety of woodpeckers, including the pileated. If the mortality 

becomes extensive and live canopy closure is lost in large areas of severe insect infestations or 

fire intensity, then affected areas would become less suitable for this species. If the mortality 

remains moderate and patchy, then the affected areas may remain suitable for this species. This 

is most likely to be sustainable on the more mesic PAGs, especially grand fir sites. Projections 

indicate that pileated woodpecker habitat would be above the HRV in 50 years under this 

alternative in the absence of large scale disturbance. 

Direct and Indirect Effects Common to Alternatives 2, 3, 4, and 5 

Within pileated feeding habitat, Alternatives 2 and 4 would reduce canopy closure, which would 

likely reduce the suitability of these areas as foraging habitat for pileated woodpeckers. 

However, within the treatment units that overlap pileated feeding habitat, prescriptions were 

modified to ensure that grand fir and Douglas-fir remain in these stands, while reducing stand 

density so that the development of large trees would be promoted. The reduction in canopy 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 191 

closure is a trade-off for the long-term benefit of providing a greater abundance of large structure 

trees, snags, and logs in the future. At the same time, snags would not be marked for removal; 

although hazard trees (tress that pose a danger to workers within work areas) would be cut down. 

Under Alternatives 3 and 5, stand density would be reduced in stands treated within pileated 

feeding habitat, but to a lesser extent than would occur under Alternatives 2 and 4. Suitability of 

habitat would be retained as the understory thinning is not expected to substantially alter canopy 

closure or the potential for future development of stem rot, and thus future nest/roost sites. 

Underburning of natural fuels can result in varied effects to pileated woodpecker habitat. When 

fire burns under relatively cool conditions with higher fuel moisture the fire may creep around 

leaving unburned and lightly burned patches, and much of the larger woody debris would be 

retained. Some individual trees may be weakened, giving advantage to insects or pathogens that 

result in foraging opportunities for woodpeckers and which set individual trees on a path toward 

developing stem rot that would ultimately make them suitable substrate for the excavation of 

future nest cavities. Burning under this type of scenario would retain sufficient canopy closure 

to maintain habitat for pileated woodpeckers while providing for the development of foraging, 

roosting, and nesting habitat over time. On the other hand, if the burning occurs under warmer 

conditions with lower fuel moisture, the combustion of woody debris (including snags) may be 

more complete, canopy closure may be reduced, crown base height may be substantially raised, 

and resulting tree mortality may be immediate rather than prolonged (less time for development 

of stem rot). Burning under this type of scenario, may reduce suitability for use by pileated 

woodpeckers due to reduced cover and nesting/roosting sites, though a pulse of foraging 

substrate may result immediately after the treatment. Often a prescribed fire will burn under a 

combination of conditions due to variation in aspect, elevation, fuel types, and changing weather 

conditions. The end result is usually a mosaic of post-fire conditions that lead to a variable 

habitat quality for a range of species. 

Thinning of small diameter trees within the Stewart Springs OGMA would release selected large 

diameter trees from understory competition. Resultant slash would be pulled away from the base 

of the trees, hand piled, and burned. This activity would improve the longevity of the selected 

large trees by reducing competitive stress and the development of ladder fuels. Because these 

activities are limited to the drier portions of the OGMA (south and west facing slopes in 

Douglas-fir and dry grand fir PAGs), the areas of the OGMA with the highest potential for 

sustaining pileated woodpecker nesting habitat (north and east facing slopes in moist grand fir 

PAGS) would remain untreated. The low intensity thinning activity would occur in patches 

where large live ponderosa pine and larch trees exist. Unthinned patches would be retained 

where large trees are absent, or where they occur less abundantly. Much of the area would 

remain suitable as foraging habitat for pileated woodpeckers. 

Alternative 2 

This alternative would commercially thin timber on 253 acres in pileated feeding habitat. 

Because the canopy may be reduced to less than 60 percent crown closure after treatment, this 

alternative would reduce the suitability of these stands as foraging or nesting habitat for pileated 

woodpeckers, at least in the short term. Canopy closure is expected to recover to some extent, as 

the retained trees expand their crowns in diameter and depth in response to the release from 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 192 

competition that results from thinning. Thinning of mid-story trees would promote the 

development of large structure trees in the future, ultimately providing a source of recruitment 

for large snags and down logs. Thus, this alternative would facilitate the development of higher 

quality nesting and roosting habitat in the long term. The prescription calls for preferential 

retention of ponderosa pine and larch, but grand fir and Douglas-fir would also be retained as 

individuals or clumps within these stands. In patches where moderate or higher levels of 

mistletoe occur in one species, understory trees of another species would be retained. This 

should promote within stand diversity and limit the impact of mistletoe on stand development. 

Precommercial thinning outside of harvest areas would occur on 67 acres of pileated feeding 

habitat. Thinning of these small trees would help to promote the development of larger trees in 

the stand. Thus, this treatment would facilitate the development of higher quality foraging 

habitat in the long term. The prescription calls for preferential retention of ponderosa pine and 

larch, but grand fir and Douglas-fir would also be retained as individuals or clumps scattered 

within these stands, especially on north and east facing slopes and in draws. 

Under burning (outside of thinning units) within pileated feeding habitat would occur on 94 

acres. This activity may reduce habitat suitability by reducing canopy closure and by altering the 

timing of mortality in grand fir and Douglas-fir. Fire is likely to result in an abundance of fire 

killed fir trees soon after the activity, providing a flush of foraging substrate, but later within 

stand mortality is expected to decline and foraging opportunities would also decline. 

No harvest or natural fuels burning would occur within OGMAs. Thinning of small diameter 

trees to release selected individual large trees would be conducted within portions of one OGMA 

(Stewart Springs) on approximately 70 acres. 

This alternative is expected to reduce the quality of pileated woodpecker feeding habitat on 414 

acres. Alternative 2 is expected to reduce the quantity of primary nesting habitat on 1,182 acres 

(26% of existing) within the project area in the short term. This alternative would result in about 

20 percent less primary nesting habitat for pileated woodpeckers in 50 years compared to no 

action, assuming that large-scale, high-intensity disturbances does not occur. Projections 

indicate that pileated woodpecker habitat would be within the HRV in 50 years under this 

alternative. Pileated woodpeckers generally would not be expected to nest within areas that are 

commercially harvested under this alternative for a period of 25-30 years on more mesic sites 

(grand fir and Douglas-fir PAGs). Precommercial thinning stands on such sites may remain 

suitable after treatment, depending on residual stocking. On xeric sites (ponderosa pine and 

juniper PAGs) primary nesting habitat would not occur whether treated or not. 

Alternative 3 

Alternative 3 has no commercial harvest in pileated feeding habitat. It includes precommercial 

thinning on 125 acres. Thinning of these small trees would promote the development of larger 

trees in the stand. This activity would facilitate the development of higher quality foraging 

habitat in the long term with minimal impact on foraging habitat in the short term. The 

prescription calls for preferential retention of ponderosa pine and larch, but grand fir and 
Chapter 3 - Affected Environment and Environmental Consequences

Douglas-fir would be retained as individuals within these stands, especially on north and east 

facing slopes and in draws. 

Prescribed natural fuels burning within pileated feeding habitat would occur on 125 acres. This 

activity may reduce habitat suitability by reducing canopy closure and by altering the timing of 

mortality in grand fir and Douglas-fir. Fire is likely to result in an abundance of fire killed fir 

trees soon after the treatment, providing a flush of foraging substrate, but later within stand 

mortality is expected to decline and thus foraging opportunities would also decline. 

No harvest or natural fuels burning would occur within OGMAs. Thinning of small diameter 

trees to release selected individual large trees would be conducted within portions of one OGMA 

(Stewart Springs) on approximately 70 acres. 

This alternative is expected to alter forest structure on 250 acres of pileated woodpecker feeding 

habitat, but retain suitability within those acres. This alternative has potential to reduce quantity

at least in the short term on these acres. The amount of primary nesting habitat would be 

reduced by 190 acres (4% of existing) within the project area in the short term. This alternative 

would result in about 4 percent less primary nesting habitat for pileated woodpeckers in 50 years 

compared to no action, assuming that large-scale, high-intensity disturbances do not occur. 

Projections indicate that pileated woodpecker habitat would be above the HRV in 50 years under 

this alternative. Precommercial thinned stands on mesic sites may remain suitable for nesting 

after treatment, depending on residual stocking and degree of crown scorch. On xeric sites 

(ponderosa pine and juniper PAGs) primary nesting habitat would not occur whether treated or 

not. 

Alternative 4 

This alternative would commercially thin timber on 131 acres in pileated feeding habitat. 

Because the canopy may be reduced to less than 60 percent crown closure after harvest, this 

alternative would reduce the suitability of these stands as foraging habitat for pileated 

woodpeckers, at least in the short term. Canopy closure is expected to recover to some extent, as 

the retained trees expand their crowns in diameter and depth in response to the release from 

competition that results from the thinning. Thinning of mid-story trees would promote the 

development of large structure trees in the future, ultimately providing a source of recruitment 

for large snags and down logs. Thus, this activity may facilitate the development of higher 

quality nesting and roosting habitat in the long term. The prescription calls for preferential 

retention of ponderosa pine and larch, but grand fir and Douglas-fir would also be retained as 

individuals or clumps within these stands. In patches where moderate or higher levels of 

mistletoe occur in one species, understory trees of another species would be retained. This 

would promote within stand diversity and limit the impact of mistletoe on stand development. 

Precommercial thinning outside of harvest areas would occur on 155 acres. Thinning of these 

small trees would help to promote the development of larger trees in the stand. Thus, this 

treatment would facilitate the development of higher quality foraging habitat in the long term. 

The prescription calls for preferential retention of ponderosa pine and larch, but grand fir and 
Chapter 3 - Affected Environment and Environmental Consequences

Douglas-fir would also be retained as individuals or clumps scattered within these stands, 

especially on north and east facing slopes and in draws. 

Prescribed natural fuels burning (outside of thinning units) within pileated feeding habitat would 

occur on 74 acres. This activity may reduce habitat suitability by reducing canopy closure and 

by altering the timing of mortality in grand fir and Douglas-fir. Fire is likely to result in an 

abundance of fire killed fir trees soon after the treatment, providing a flush of foraging substrate, 

but later within stand mortality is expected to decline and thus foraging opportunities would also 

decline. 

No harvest or natural fuels burning would occur within OGMAs. Thinning of small diameter 

trees to release selected individual large trees would be conducted within portions of one OGMA 

(Stewart Springs) on approximately 70 acres. 

Alternative 4 is expected to reduce the quality of pileated woodpecker feeding habitat on 360 

acres. This alternative is expected to reduce quantity of primary nesting habitat on 996 acres 

(22% of existing) within the project area in the short term. This alternative would result in about 

17 percent less primary nesting habitat for pileated woodpeckers in 50 years compared to no 

action, assuming that large-scale, high-intensity disturbances do not occur. Projections indicate 

that pileated woodpecker habitat would be within the HRV in 50 years under this alternative 

Pileated woodpeckers generally would not be expected to nest within areas that are commercially 

harvested under this alternative for a period of 25-30 years on more mesic sites (grand fir and 

Douglas-fir PAGs). Precommercial thinned stands on such sites may remain suitable after 

treatment, depending on residual stocking and degree of crown scorch. Primary nesting habitat 

would not occur on xeric sites (ponderosa pine and juniper PAGs). 

Alternative 5 

This alternative would not commercially harvest timber in pileated feeding habitat. The 

suitability of these stands as foraging habitat for pileated woodpeckers, at least in the short term 

would be retained. Development of large structure trees in the future would continue at a slower 

pace than might occur if the stands were thinned. 

Precommercial thinning outside of harvest areas would occur on 264 acres. Thinning of these 

small trees would promote the development of larger trees in the stand. The prescription would 

include retention of dense patches throughout treated stands in order to provide cover and 

foraging substrate. This activity would facilitate the development of higher quality foraging 

habitat in the long term with minimal impact on foraging habitat in the short term. The 

prescription calls for preferential retention of ponderosa pine and larch, but grand fir and 

Douglas-fir would be retained as individuals or clumps scattered within these stands, especially 

on north and east facing slopes and in draws. This activity may reduce habitat suitability by 

reducing canopy closure and by altering the timing of mortality in grand fir and Douglas-fir. 

Prescribed natural fuels burning within pileated feeding habitat would occur on 57 acres. Fire is 

likely to result in an abundance of fire killed fir trees soon after the activity, providing a flush of

foraging substrate, but later within stand mortality is expected to decline and thus foraging 

opportunities would also decline. 

No harvest or natural fuels burning would occur within OGMAs. Thinning of small diameter 

trees to release selected individual large trees would be conducted within portions of one OGMA 

(Stewart Springs) on approximately 70 acres. 

Alternative 5 is expected to alter quality of pileated woodpecker feeding habitat on 320 acres, but 

retain suitability on those acres. This alternative is expected to reduce quantity of primary 

nesting habitat on 1,048 acres (23% of existing) within the project area in the short term. This 

alternative would result in about 18 percent less primary nesting habitat for pileated 

woodpeckers in 50 years compared to no action, assuming that large-scale, high-intensity 

disturbances do not occur. Projections indicate that pileated woodpecker habitat would be within 

the HRV in 50 years under this alternative. Outside of areas with modified prescriptions, 

pileated woodpeckers generally would not be expected to nest within areas that are commercially 

harvested under this alternative for a period of 25-30 years on more mesic sites (grand fir and 

Douglas-fir PAGs). Within areas with modified prescriptions (connective corridors, goshawk 

post-fledging areas, pileated feeding habitat, satisfactory cover, etc.) and within precommercial 

thinned stands on such sites habitat may remain suitable after treatment.

Cumulative Effects 

Harvest activities have occurred on 7,563 acres in the project area. Pileated feeding habitats are 

generally delineated outside of previously harvested areas, though some acres within pileated 

feeding habitat have received some level of hazard tree removal, salvage harvest, or woodcutting 

in the past. The majority of the previous harvest resulted in removal of most or all of the 

overstory trees rendering these areas unsuitable for pileated woodpeckers. This intensity of 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 196 

treatment occurred on approximately 3,263 acres in Lower Marks Creek, 2,799 acres in Upper 

Marks Creek, and 7 acres in Veazie Creek. Prescriptions that retained approximately 4-6 live 

overstory trees would provide for some future large snag and log habitat as the younger stand 

develops into a mature stand, but would have removed pileated woodpecker habitat. This type of 

treatment occurred on approximately 220 acres in Lower Marks Creek and 298 acres in Upper 

Marks Creek. Shelterwood harvests would not have retained enough overstory trees to provide 

pileated woodpecker habitat. However, such stands do retain structure that may contribute to 

both the overstory and the snag and down wood components in the future as the stand develops 

around them. Shelterwood harvests occurred on approximately 261 acres in Lower Marks Creek 

and 562 acres in Upper Marks Creek. Removal of snags for firewood, for hazard abatement, or 

under salvage sales (e.g. Cougar Salvage) would have reduced habitat for woodpeckers. At the 

same time that pileated woodpecker habitat was being reduced within timber harvest units, fire 

suppression activities were being implemented across all plant associations. As a result of this 

fire exclusion, grand fir developed in the understory of many stands that were previously 

dominated by ponderosa pine and larch. In these stands, pileated woodpecker habitat has 

increased compared to historic conditions. 

Implementation of Viable Ecosystems and efforts to reduce hazardous fuel accumulations at the 

watershed and Forest level will continue to remove fir from many forested stands, resulting in 

increased domination of pine and larch, more open forest conditions and single stratum stand 

structure on more acres than is currently present. This will reduce the quality of pileated 

woodpecker habitat in the long term on these areas. At the same time, stands that have 

developed densities and species compositions that are not sustainable due to site capability, 

would be brought closer to a sustainable level. At the watershed scale, the abundance and 

distribution of pileated woodpecker habitat would be closer to the historic level. Habitat for 

pileated woodpeckers would be concentrated on sites that are more likely to sustain such stand 

densities and species distributions, and would be eliminated from sites that are less likely to 

sustain it in the long term. 

Ongoing and reasonably foreseeable activities would continue to interact with pileated 

woodpeckers and their habitat. Ongoing grazing, recreational use, and exclosure maintenance 

activities are not expected to result in effects to this species when combined with effects of this 

project. However, ongoing firewood cutting may combine with this project to further reduce 

habitat for pileated woodpeckers. When implemented within the rules established by the 

firewood synopsis, there should be no net cumulative effect. However, people continue to 

remove large snags illegally, accessing them cross country or on old timber harvest access 

routes. This project proposes to harvest up to 5,366 acres with ground-based equipment and 

proposes to construct/reconstruct up to 30 miles of road. Though all new roads are scheduled to 

be closed and additional existing roads are planned to be closed after project activities are 

completed, some people are likely to utilize these road beds for a period of time before closures 

are implemented (some people may breach closures after they are implemented) in order to 

access firewood. This project may contribute to increased accessibility and thus additional area 

vulnerable to illegal snag removal which would reduce potential nesting habitat for this species 

and other primary cavity excavators. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 197 

Primary Cavity Excavators 

Primary cavity excavators are Management Indicator Species (MIS) listed in the Ochoco Forest 

Plan (FEIS p. 3-21) as wildlife species that consistently excavate their own cavities. 

The primary cavity excavators that occur on Ochoco National Forest are Lewis’ woodpecker, 

red-naped sapsucker, Williamson’s sapsucker, hairy woodpecker, downy woodpecker, whiteheaded woodpecker, black-backed woodpecker, three-toed woodpecker, pileated woodpecker 

and northern flicker. These species excavate cavities in wood that they use to nest in, and which 

may subsequently be used by other species (secondary cavity nesters). Two other groups of 

species, the nuthatches and chickadees sometimes excavate their own cavities and sometimes use 

existing cavities as secondary nesters. In this analysis, the black-capped chickadee and redbreasted nuthatch are represented by primary cavity excavators that use dense forest or riparian 

woodlands, while the mountain chickadee, pygmy nuthatch, and white-breasted nuthatch are 

represented by primary cavity excavators that use xeric open forest habitats. 

The existing condition of habitat for primary excavators in conifer forest focuses on three 

species, the white-headed woodpecker, the pileated woodpecker, and the northern flicker. These 

three species represent the range of forest conditions from open, single-story dry forest to dense 

multiple-story mesic forest. These species are indicators for the range of habitat conditions 

utilized by conifer forest-dwelling primary cavity excavators that would be present in the project 

area. The white-headed and pileated woodpeckers also have higher requirements than the other 

species of primary cavity excavators either in terms of snag numbers, size, or both. Whiteheaded woodpeckers are an indicator for open forest conditions in pine stands, while pileated 

woodpeckers are an indicator for dense forest conditions on more mesic sites. Though the 

northern flicker is a habitat generalist, it was chosen as a species to represent availability of snag

habitat in old-growth juniper woodlands. The discussion on northern flicker has an emphasis 

placed on the discussion of old-growth juniper, though total habitat for the species can occur 

across all forest types within the project area, and the preferred nesting habitat within this project

area is represented by the white-headed woodpecker. Species that select for special habitats such 

as aspen or that are listed as focal species for priority habitats in the Partners in Flight Northern 

Rocky Mountains Bird Conservation Plan are discussed in the section on neotropical birds. 

These include Lewis’ woodpecker and red-naped sapsucker. The aspen loving red-naped 

sapsucker is an indicator of two other primary cavity excavators that select for riparian 

woodlands: Williamson’s sapsucker and black-capped chickadee. The black-backed 

woodpecker is discussed in the neotropical birds section, because it is associated with a priority 

habitat listed there. The analysis of management indicator species and the neotropical birds 

section combined represent the needs and effects to all of the primary cavity excavators found on 

the Ochoco National Forest. The January 29, 2007, Spears Wildlife Report includes more 

information on primary cavity excavators. 

White-headed Woodpecker 

Affected Environment 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 198 

The white-headed woodpecker prefers ponderosa pine habitat that has more open stand 

conditions with large pine for foraging and large snags for nesting habitat. The white-headed 

woodpecker is an indicator of more xeric LOS forests. They typically select for single-strata 

ponderosa pine dominated LOS forests. Its habitat associates are generally called the pine birds, 

including the pygmy and white-breasted nuthatches and the flammulated owl. This habitat type 

is also a preferred habitat for the northern flicker in the Blue Mountains of Oregon (Marshall et 

al. 2003). This habitat is used by all of the other primary cavity excavators with the exception of 

the pileated woodpecker, red-breasted nuthatch, and three-toed woodpecker, which prefer mixed 

conifer habitat with a fir component, and downy woodpecker and black-capped chickadee which 

are largely restricted to riparian woodlands. Open forest conditions are also preferred by Lewis’ 

woodpecker, northern flicker, Williamson’s sapsucker, pygmy and white-breasted nuthatches, 

and mountain chickadee. Current conditions in the Spears project area are limiting for whiteheaded woodpecker, with single-strata LOS forests being below the HRV in dry grand fir, 

Douglas-fir, and ponderosa pine PAGs. The existing condition is currently deficient in whiteheaded woodpecker habitat within the project area when compared to the HRV as shown in 

Table 66.

The white-headed woodpecker prefers open canopy, late to old growth pine-dominated habitat. 

They prefer stands with live old ponderosa pine, abundant snags, and relatively open understory 

conditions. White-headed woodpeckers favor live ponderosa pine as foraging substrate, but have 

been observed in lodgepole pine, sugar pine, Engelmann spruce, and other species. They 

concentrate their foraging activities on live ponderosa pine, but they may also glean insects from 

other tree species. They generally select large diameter ponderosa pine snags as nest sites, 

though they are not always in tall snags (Dixon 1995 and Marshall 1997). Though the 

population has been reported as increasing across the western states (Wisdom et al. 2000), there 

have been local population declines in the Blue Mountains (Csuti et al. 1997) and on Deschutes 

and Winema National Forests (Marshall et al. 1997). Breeding bird survey data show no 

significant change in population for this species in the western states (Marshall et al. 1997). 

Within the project area, white-headed woodpeckers have been observed foraging in open 

forested areas, and potential nest holes have been noted in medium to large diameter pine snags 

and hollow live trees. 

Environmental Consequences 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 199 

Alternative 1 

The current trends in snag and large wood abundance would continue to occur. The amount of 

existing snags present within the project area would not be altered by implementation of this 

alternative, though continued competitive stress would likely result in mortality of trees and thus 

recruitment of snags and down wood. Concurrently, the build up of fuels and canopy conditions 

that favor crown fires and high fire intensity may ultimately facilitate a stand replacing 

disturbance event. Such events yield an abundance of snags in the short term, but may result in 

large areas devoid of snags in 50 to 100 years afterwards (after the majority of the initial pulse of 

snags has fallen down). Large snag recruitment would begin again after the new stand matures 

enough to provide such structure. This may take 150 years or more. 

This alternative would maintain the existing acres of fir-dominated understories and the trend 

toward fir dominated habitats. The no action alternative would favor the species that utilize firdominated habitats, by maintaining this habitat within the HRV. There would be a continued 

decline in white-headed woodpecker habitat which prefers open, pine dominated stands. This 

alternative would not move towards the HRV for the white-headed woodpecker and its 

associates. The trend of decreasing open forest and single-strata LOS would continue in the 

short term as understory trees fill in from below. Of the approximately 1,400 acres of LOS 

forests that have been identified in the project area, 66 percent is in dry grand fir or ponderosa 

pine plant associations. These relatively more xeric areas are the least likely to be able to sustain

multi-strata LOS in the long term. Mortality due to stand densities being above sustainable 

levels would result in loss of foraging habitat for white-headed woodpeckers (live pine) as the 

overstory pine trees succumb to stress from competition in overstocked stands. 

This alternative would not restore habitat for white-headed woodpeckers. This habitat type 

would remain below HRV. Over time, stand conditions area expected to decline on sites that 

cannot sustain high densities of conifers. As trees on such sites succumb to insect invasion they 

would stop producing seeds, sap, and invertebrates associated with foliage. These are listed as 

important food resources for this species (Marshall et al. 2003). If the mortality becomes 

extensive and live canopy closure is lost in large areas of severe insect infestations or fire 

intensity, then affected areas would become less suitable for this species. If the mortality 

remains moderate and patchy, then the affected areas may become more suitable for this species 

which prefers relatively open forest conditions. Projections indicate that white-headed 

woodpecker habitat would remain below the HRV in 50 years in the absence of large scale 

disturbance. 

Direct and Indirect Effects Common to Alternatives 2, 3, 4, and 5 

All existing snags would be left that are not deemed to be a safety hazard. The amount of 

existing snags present within the project area should not be substantially altered by 

implementation of any of the alternatives. Thus, the percent tolerance for species evaluated 

under DecAID would not be affected in the short term. However, the alternatives do set treated 

stands on different courses for rate of large tree development. Snags and down wood may be 

consumed by prescribed fire. This would be partially offset by the creation of down wood due to 

fire-killed trees. The effect of fire on snag retention would likely result in a higher number of 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 200 

hard snags, with a concurrent reduction in soft and hollow snag habitat. Because of anticipated 

low-fire intensity, it is also likely that while large existing snags may be consumed by fire, the 

snags created by fire would tend to be in smaller size classes due to the vulnerability to fire 

mortality of smaller, thin barked trees. 

Reduction of understory tree density within treated areas would reduce the abundance of dense, 

fir-dominated understory conditions, and increase the abundance of more open stand structure 

with ponderosa pine contributing a relatively larger percentage of the species composition. This 

would result in reduced abundance of habitat for species that select for dense multi-layered 

forests, such as the pileated woodpecker and red-breasted nuthatch, while providing an increased 

abundance of habitat for species that prefer more open pine dominated stands, such as the whiteheaded woodpecker and white-breasted nuthatch. 

Alternative 2 

This alternative would treat 6,172 acres with commercial harvest. In these units all existing 

snags would be left that are not deemed to be a safety hazard during timber operations. The 

intent is to have at least the number and sizes of snags and down wood as prescribed in the 

Regional Forester’s Plan Amendment 2. All existing snags and down logs (>12 inches small 

end) are to be retained (with the exception of safety hazards). 

Underburning would occur on 5,511 acres outside of harvest and thinning units and on 9,953 

acres within harvest and thinning units. 

This alternative would help restore white-headed woodpecker habitat on most of the commercial 

harvest area. Where precommercial thinning occurs in two-storied stands with a component of 

large live ponderosa pine and suitable snags for nesting, this activity would help restore whiteheaded woodpecker habitat. Precommercial thinning in young stands promotes the development 

of large pine in the future, and thus habitat for white-headed woodpecker. This alternative treats 

11,356 acres by precommercial or hardwood restoration thinning. This alternative is expected to 

restore white-headed woodpecker habitat on 3,460 acres. This alternative would reduce the 

understory fir component on acres dominated by ponderosa pine and western larch. 

Alternative 2 is expected to restore white-headed woodpecker habitat on 3,460 acres moving this 

habitat type into HRV post-treatment. This alternative would result in about 29 percent more 

primary nesting habitat for white-headed woodpeckers in 50 years compared to no action. 

Projections indicate that white-headed woodpecker habitat would be below the HRV in 50 years 

under this alternative, unless maintained in the future. White-headed woodpeckers would be 

expected to nest within commercially harvested areas for up to 15 years on mesic sites (grand fir 

and Douglas-fir PAGs), or up to 30 years on more xeric sites (ponderosa pine PAGs). 

Precommercial thinned stands on such sites may be suitable after treatment, depending on 

residual stocking and degree of crown scorch. 

Alternative 3 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 201 

Alternative 3 has no commercial harvest, but would still treat forest stands on 9,899 acres with 

precommercial or hardwood restoration thinning. Small trees up to 12 inches dbh would be 

subject to precommercial thinning. Prescribed underburning would occur on 5,603 acres outside 

of thinning units and on 8,323 acres in precommercial thinning units. 

The effects of this alternative would reduce the amount of overstocked stands by thinning 

understory trees. This alternative would not create the open habitats preferred by the pine birds 

except on acres dominated by trees less than 12 inches dbh trees and in two storied stands with 

dense small tree cover under the large tree overstory. It would not reduce fir dominated mid and 

understories as much as the commercial harvest alternatives, as many of these trees are larger 

than 12 inches dbh. 

Where precommercial thinning occurs in two-storied stands with a component of large live 

ponderosa pine and suitable snags for nesting, this activity would help restore white-headed 

woodpecker habitat. However, this activity would not be as effective in multi-storied stands as 

commercial harvest, where the mid-story trees are thinned more aggressively. Thinning of 

young stands would promote development of future white-headed woodpecker habitat on pine 

sites. This alternative would have the least effect of the action alternatives on white-headed 

woodpecker habitat, because treated stands would likely retain a higher canopy closure and true 

fir component than would be present in commercially harvested stands of the other alternatives. 

This alternative is expected to restore white-headed woodpecker habitat on 1,084 acres. 

This alternative is expected to alter forest structure sufficiently enough to restore habitat for 

white-headed woodpeckers on 1,084 acres moving this habitat type into HRV post-treatment. 

This alternative would result in about 10 percent more primary nesting habitat for white-headed 

woodpeckers in 50 years compared to no action. Projections indicate that white-headed 

woodpecker habitat would be below the HRV in 50 years under this alternative. Stands may be 

suitable for nesting after treatment on mesic sites (grand fir and Douglas-fir PAGs) for up to 15 

years, or up to 30 years on xeric sites (ponderosa pine PAGs) depending on residual stocking and 

degree of crown scorch. 

Alternative 4 

This alternative treats 4,935 acres with commercial harvest. In these units all existing snags 

would be left that are not deemed to be a safety hazard. The intent is to have at least the number 

and sizes of snags and down wood as prescribed by the Eastside Screens. All existing snags and 

down logs (>12 inch diameter small end) are to be retained. 

This alternative would help restore white-headed woodpecker habitat on most of the commercial 

harvest area. Where precommercial thinning occurs in two-storied stands with a component of 

large live ponderosa pine and suitable snags for nesting, this treatment would help restore whiteheaded woodpecker habitat. Precommercial thinning in young stands promotes the development 

of large pine in the future, and thus habitat for white-headed woodpecker. This alternative treats 

11,131 acres by precommercial or hardwood restoration thinning. Underburning would occur on 

5,338 acres outside of thinning units and 9,824 acres within thinning units. This alternative is 

expected to restore white-headed woodpecker habitat on 3,132 acres. The effects of this 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 202 

alternative would reduce acres of overstocked stands and reduce the understory fir component on 

acres dominated by ponderosa pine and western larch. 

This alternative is expected to restore white-headed woodpecker habitat on 3,132 acres moving 

this habitat type into HRV post-treatment. This alternative would result in about 26 percent 

more primary nesting habitat for white-headed woodpeckers in 50 years compared to no action. 

Projections indicate that white-headed woodpecker habitat would be below the HRV in 50 years 

under this alternative, unless maintained in the future. White-headed woodpeckers would be 

expected to nest within areas that are treated for up to 15 years on mesic sites (grand fir and 

Douglas-fir PAGS), or up to 30 years on more xeric sites (ponderosa pine PAGs). 

Precommercial thinned stands on such sites may be suitable after treatment, depending on 

residual stocking and degree of crown scorch. 

Alternative 5 

This alternative treats 3,942 acres with commercial harvest. In these units all existing snags 

would be left that are not deemed to be a safety hazard. The intent is to have at least the number 

and sizes of snags and down wood as prescribed by the Regional Forester’s Plan Amendment 2. 

All existing snags and down logs (>12 inch diameter small end) are to be retained (with the 

exception of safety hazards). 

This alternative would help restore white-headed woodpecker habitat on commercial harvest 

units that are not within goshawk PFAs, connective corridors, satisfactory elk cover in winter 

range, or in mesic north or east facing swales. In harvest units within these habitats, the harvest 

prescription is less aggressive, so would not do as well at promoting habitat suitability for whiteheaded woodpeckers, as the more intensive treatments elsewhere under this alternative or under 

Alternatives 2 or 4. Where precommercial thinning occurs in two-storied stands with a 

component of large live ponderosa pine and suitable snags for nesting, this treatment would help 

restore white-headed woodpecker habitat. Precommercial thinning in young stands promotes the 

development of large pine in the future, and thus habitat for white-headed woodpecker. This 

alternative treats 11,270 acres by precommercial or hardwood thinning. Underburning would 

occur on 4,702 acres outside of harvest and thinning units and on 9,503 acres within harvest and 

thinning units. This alternative is expected to restore white-headed woodpecker habitat on 3,220 

acres. The effects of this alternative would reduce acres of overstocked stands and reduce the 

understory fir component on acres dominated by ponderosa pine and western larch. 

This alternative is expected to restore white-headed woodpecker habitat on 3,220 acres posttreatment. This alternative would result in about 29 percent more primary nesting habitat for 

white-headed woodpeckers in 50 years compared to no action. Projections indicate that whiteheaded woodpecker habitat would be below the HRV in 50 years under this alternative, unless 

maintained in the future. White-headed woodpeckers would be expected to nest within areas that 

are commercially harvested under this alternative for up to 15 years on mesic sites (grand fir and 

Douglas-fir PAGs), or up to 30 years on more xeric sites (ponderosa pine PAGs). 

Precommercial thinned stands on such sites may be suitable after treatment, depending on 

residual stocking and degree of crown scorch. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 203 

Cumulative Effects 

Harvest activities have occurred on 7,563 acres in the project area. The majority of the 

previously harvested areas received harvest prescriptions which removed most or all of the 

overstory trees limiting both nesting and foraging habitat in these areas for white-headed 

woodpeckers. This intensity of treatment occurred on approximately 3,263 acres in Lower 

Marks Creek, 2,799 acres in Upper Marks Creek, and 7 acres in Veazie Creek. Prescriptions that 

retain 4-6 live overstory trees may provide suitable habitat for white-headed woodpeckers as 

long as live ponderosa pine and at least 2.25 large snags per acres are present (Thomas et al. 

1979). This intensity of treatment occurred on approximately 220 acres in Lower Marks Creek 

and 298 acres in Upper Marks Creek. Shelterwood harvests may retain enough overstory trees to 

provide suitable white-headed woodpecker nesting habitat. Stands with at least 12 trees per acre 

greater than 21 inches dbh may be comparable to stands that are known to have been used 

successfully by nesting white-headed woodpeckers (Marshall et al. 2003). Such stands provide 

live large tree structure currently and may contribute to both the overstory and the snag and 

down wood components in the future. Shelterwood harvests occurred on approximately 261 

acres in Lower Marks Creek and 562 acres in Upper Marks Creek. Removal of snags for 

firewood, as hazard abatement, or under salvage sales (e.g. Cougar Salvage) would have reduced 

habitat for white-headed woodpeckers (Wisdom et al. 2000). Fire exclusion has resulted in 

grand fir developing in the understory of many stands that were previously dominated by 

ponderosa pine and larch. This has contributed to loss of open forest conditions and potential 

increases in predation (Marshall et al. 2003). As a result of past management practices, whiteheaded woodpecker habitat has decreased compared to historic conditions. 

Implementation of Viable Ecosystems and efforts to reduce hazardous fuel accumulations at the 

watershed and Forest level would continue to restore more open forest conditions in many 

forested stands, resulting in increased dominance of pine and larch and single stratum structure 

on more acres than is currently present. This would improve the quality of white-headed 

woodpecker habitat on these areas. At the watershed scale, the abundance and distribution of 

white-headed woodpecker habitat would become within the historic level in the short-term under 

all action alternatives. Keeping white-headed woodpecker habitat within HRV in the long term 

would require future maintenance. 

Ongoing and reasonably foreseeable activities would continue to interact with white-headed 

woodpeckers and their habitat. Ongoing grazing, recreational use, and exclosure maintenance 

activities are not expected to result in effects to this species when combined with effects of this 

project. However, ongoing firewood cutting may combine with this project to further reduce 

habitat for white-headed woodpeckers. When implemented within the rules established by the 

firewood synopsis, there should be no net cumulative effect. However, people continue to 

remove large snags illegally, accessing them cross country or on old timber harvest access 

routes. This project proposes to harvest up to 5,366 acres with ground-based equipment and 

proposes to construct/reconstruct up to 30 miles of road. Though all new roads are scheduled to 

be closed and additional existing roads are planned to be closed after project activities are 

completed, some people are likely to utilize these road beds for a period of time before closures 

are implemented (some people may breach closures after they are implemented) in order to 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 204 

access firewood. As described above for pileated woodpeckers, this project may contribute to 

increased accessibility and thus additional areas vulnerable to illegal snag removal, which would 

reduce potential nesting habitat for this species and other primary cavity excavators. 

Northern (Common) Flicker 

Affected Environment 

Northern flicker prefers open forests and forest edges, though they can be found in a wide variety 

of terrestrial habitats in Oregon. They tend to avoid very dense forested areas. They will nest in 

a variety of tree species with decay in them. In the Blue Mountains, they are known to nest in 

ponderosa pine, Douglas-fir, western larch, and lodgepole pine. In central Oregon, flickers were 

found to select old-growth juniper over mid-successional juniper (Marshall et al. 2003). The 

most preferred habitat conditions for this species is provided for in open condition ponderosa 

pine and Douglas-fir PAGs which are analyzed above in the section on white-headed 

woodpeckers. The direct, indirect, and cumulative effects described for white-headed 

woodpeckers best represent the effects to northern flickers in the project area. The following 

discussion applies to the old-growth juniper habitat type and the role it may play in providing for 

the northern flicker within the project area, even though it is not necessarily the primary 

preferred habitat for the species within this project area. 

Of the approximately 1,400 acres of LOS stands that have been identified in the project area, a 

negligible amount were in western juniper PAG. However, juniper also occurs in the early-seral 

stages of the ponderosa pine and Douglas-fir PAGs, so individual old-growth juniper trees may 

occur in these sites as well as in the western juniper PAG. 

Environmental Consequences 

Alternative 1 

The current trends in snag and large wood abundance would continue to occur. The amount of 

existing juniper snags and live juniper with hollow spaces present within the project area would 

not be altered by this alternative. The build up of fuels and canopy conditions would continue, 

and would ultimately favor stand replacing fire events. This would not be an atypical fire regime 

in this habitat type. Such events yield an abundance of snags of varying heights and diameters. 

Juniper snags may tend to stand for many years following fire unless they are in a location that 

can be easily accessed by firewood cutters. Snag and cavity tree recruitment would begin again 

after the new stand matures enough to provide such structure. Development of snags and trees 

with stem rot (decay that allows excavation to be possible) of sufficient size to accommodate 

nesting flickers may take 200 years or more after a stand-replacing fire. 

This alternative would maintain the existing acres of juniper stands and dense developing 

understory conditions. This alternative would not move juniper woodland and juniper steppe 

PAGs towards the HRV for open stands of large structure juniper trees, and would not reduce the 

potential for stand replacing fire events. The trend of decreasing open woodland juniper LOS 

would continue in the short term as understory trees fill in from below. This alternative would 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 205 

not remove juniper from the understory of pine, Douglas-fir, or grand fir sites, so potential 

replacement trees for juniper LOS would not be reduced. The growth rate of potential 

replacement trees would not be improved under this alternative. Because old-growth juniper is 

not a an extensive habitat feature within this project area, and because northern flickers are 

expected to select for more favorable nest sites such as large diameter pine, fir, or larch where 

they are available, the effect of this alternative on old-growth juniper is expected to have a 

negligible effect on northern flickers. 

Alternatives 2, 3, 4, and 5 

Under the action alternatives, no old-growth juniper would be removed, except incidentally such 

as in clearing for road construction or landings. Some individual old-growth trees may be killed 

by prescribed burning if ground and ladder fuels are sufficient to carry the fire into them. 

However, the old-growth juniper trees are often on rocky areas that do not sustain fire spread. 

That is why the juniper has developed into old growth on those sites. The amount of existing 

juniper snags and large, live juniper with hollow spaces present within the project area would not 

be altered by implementation of the action alternatives. However, the number of potential 

replacement trees would be reduced, as young and small diameter juniper trees would be targeted 

for removal to achieve stand density objectives. The trees that are retained during thinning 

operations, whether juniper or other species, would benefit from the density reduction in both 

growth rate and reduction of risk of loss to high intensity disturbance (fire, insects, and disease). 

Thus, though there may be fewer small juniper trees retained under the action alternatives, most 

of the larger and older juniper trees would be retained. 

These alternatives would maintain the majority of the existing old-growth juniper trees, but 

would reduce the acres in dense developing understory conditions (including juniper). This 

alternative would move juniper woodland and juniper steppe PAGs towards the HRV for open 

stands of large structure juniper trees, and would reduce the potential for stand replacing fire 

events. The trend of decreasing open woodland juniper LOS would be slowed in treated stands 

as young trees are thinned from below. These alternatives would remove juniper from the 

understory of pine, Douglas-fir ,or grand fir sites, so potential future juniper tree density would 

be reduced, however the growth rate of retained trees (including potential replacement LOS) 

would be improved under these alternatives. Because old-growth juniper is not a an extensive 

habitat feature within this project area, and because northern flickers are expected to select for 

more favorable nest sites such as large diameter pine, fir, or larch where they are available, the 

effect of these alternatives on old-growth juniper is expected to have a negligible effect on 

northern flickers in this project area. 

Cumulative Effects 

There are no present or reasonably foreseeable future activities that would alter old-growth 

juniper habitats within the project area. Therefore, there are no cumulative effects related to oldgrowth juniper habitat. 

Snags and Down Wood 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 206 

The Eastside Screens provide direction on dead wood retention, including both snags and logs. 

The Interim Wildlife Standard, Scenario A, specifies that all sale activities will maintain snags 

and green replacement trees greater than or equal to 21 inches dbh (or the representative 

overstory tree dbh if less than 21 inches), at the 100 percent potential population levels of 

primary cavity excavators. The Eastside Screens state that this should be determined using the 

best available science on species requirements as applied through current snag models or other 

documented procedures. 

Recently, the Decayed Wood Advisor (DecAID) (Mellen et al. 2002) has become available for 

use. This work is an advisory tool to help land managers evaluate effects of forest conditions 

and existing or proposed management activities on organisms that use snags, down wood, and 

other wood decay elements. In this publication, it is possible to relate the abundance of dead 

wood habitat, both snags and logs, to the frequency of occurrence of various wildlife species that 

require dead wood habitat for some part of their life cycle. DecAID shows levels based upon 

“percentage of tolerance.” This tolerance can be viewed as representation of levels of 

“assurance” or confidence of providing habitat for a particular species. However, the data 

displayed in DecAID is merely a summary of the conditions present in research plots that have 

been studied and is dependent on available research data (within each habitat type and for each 

species). DecAID does provide data on snag abundance and distribution in unharvested study 

areas that can be used as a basis of comparison for reference conditions within various habitat 

types. It also provides data on wildlife use observed in studies that have been conducted which 

can be used to help predict species responses to varying snag and down wood levels in various 

habitat types. 

Affected Environment 

The Hash Rock Fire burned approximately 4,600 acres within the Marks Creek Watershed in the 

fall of 2000. The majority of these acres were impacted by low-intensity fire that tended to thin 

young trees from the understory and consume some of the large wood on the forest floor. The 

fire did burn moderate to hot in three locations in the Hamilton, Reilly, and McGinnis Creek 

drainages. In these locations, there were 20 to 30-acre hotspots that killed most of the overstory 

trees. Following the Hash Rock Fire increased mortality began to occur in all diameter classes of 

ponderosa pine. Initially, the mortality occurred within the perimeter of the Hash Rock fire 

although additional mortality began to show up outside the fire perimeter. As a result of the 

increase in snags within the watershed, habitat for primary cavity excavators and other species 

that depend on dead would habitat was increasing. 

Dead wood (standing or down) plays an important role in overall ecosystem health, soil 

productivity, and numerous species’ habitat. Many wildlife species depend on snags and 

downed wood for roosting, denning, or feeding. In the Blue Mountains of Oregon and 

Washington, 62 species of birds and mammals use snags in some portion of their life functions 

(Thomas 1979). Snags come in all sizes and start as standing hard snags and through time begin 

to break down and eventually decay into soil nutrients. Various species utilize snags at various 

stages throughout the decay process. The goal is to manage for a variety of snag sizes, in various 

stages of decay and at various densities across the landscape to maintain viable populations of 

the variety of species that depend on them. Currently, the Ochoco National Forest is using the 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 207 

Viable Ecosystems Management Guide or 2.25 snags per acres (Thomas 1979) to determine the 

number of snags to retain. The minimum number is 2.25 snags per acres, as described in 

Thomas (1979). The Viable Ecosystems Management Guide describes a range of snag densities 

that could historically exist across the landscape in different PAGs. 

Snag management guidelines were developed for the Marks Creek Watershed using a variety of 

information including scientific literature, standards and guidelines in the Forest Plan, local 

knowledge of the area, and information contained in the DecAID advisory tool. 

Snag and down wood levels are best analyzed at scales of subwatersheds or 20 square miles 

(Mellen et al. 2002). Wisdom et al. (1999) recommends a subwatershed scale for sampling 

snags. The recent (2004) Cougar Salvage Project analysis collected information on size, density, 

and distribution for the approximately 38,800-acre Marks Creek Watershed. No information was 

collected for the non-forest portion of the watershed or the juniper woodlands portion. 

The following methods were used to determine existing snag densities for the Marks Creek 

Watershed (from Cougar Salvage analysis). The desire was to conduct a total count of snags for 

the watershed using a conservative method that would not over estimate existing snag densities. 

Comparing survey data with information that was collected on the ground from the same 

locations and considering the survey techniques, indications are that the survey underestimated 

current snag levels by approximately 25 percent. 

First, low-level helicopter flights were flown over the entire watershed. Recently dead trees 

were counted. Recently dead was defined as having the majority of the crown with red needles. 

In general, individual trees were not inventoried and snags with no red needles were also not 

inventoried. Snags were recorded as greater than 20 inches dbh and less than 20 inches dbh. 

Species were recorded for fir and pine. Smaller groups of dead trees were recorded as points and 

when larger areas of scattered dead trees or larger groups of dead trees were surveyed, they were 

recorded as polygons. A district wildlife biologist and the forest wildlife biologist conducted the 

surveys. Ground truthing on selected sites indicated that aerial surveys under estimated snag 

densities when numbers of snags exceeded approximately 50. 

Second, snag densities were obtained from the district silviculturist for that portion of the Hash 

Rock fire that occurred within the Marks Creek Watershed. Snag density estimates for the burn 

area was obtained using stand exam information; CVS plot data, and burn intensities within the 

fire. Even though some survey data points from the helicopter survey occurred within the Hash 

Rock fire perimeter, the survey concentrated outside the Hash Rock fire perimeter. Observations 

that were made during the 2004 helicopter survey indicated that a large amount of mortality has 

occurred in stands within the Hash Rock fire perimeter and on the edges of the perimeter that 

was not initially dead following the fire. 

Finally, in an attempt to capture a portion of the dead trees existing prior to the 2004 helicopter 

survey, data from the Insect and Disease survey, conducted annually by the USDA Forest 

Service and the Oregon Department of Forestry was included. Information was included from 

the years 1999 through 2003. Information from the 2004 insect and disease survey that did not 

overlap with the 2004 helicopter survey was also included. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 208 

The combined survey data provided snag information: (1) to evaluate existing conditions for the 

Marks Creek Watershed,(2) to develop retention guidelines for salvage areas, and (3) for 

comparison of direct and indirect effects of alternatives. Snags will be addressed as they relate 

to size, density, and distribution. 

Tables 67 and 68 summarize all information collected for dead trees within the approximately 

38,800 acre Marks Creek Watershed by PAG. The tables also display the VEMG guidelines and 

the prescribed retention levels by PAG. No information was collected for the juniper woodland 

community and non-forest portion of the project area.

Survey data (Tables 67 and 68) indicate that on the watershed scale the project area is currently 

below the low end of the range for snag density in both size classes in the moist grand fir, 

Douglas-fir, and moist pine PAGs. In the dry grand fir PAG, and in less than 20 inch dbh trees, 

the project area is slightly above the low end of the range for snag density, but slightly below the 

range for snag density in snags greater than or equal to 20 inches dbh. In dry pine PAGs, 

existing snag density is within the VEMG range in both size classes. The purpose of the 

watershed scale look at snag densities is to provide guidance for the management of snags at the 

project or unit scale. As a result of current levels being below or at the low end of the range, the 

prescription within treatment areas is to manage at the higher end of the range. 

Information obtained from DecAID was used to compare how snags may have been historically 

distributed across the landscape with the distribution that currently exists. Table 69 displays 

distribution data from unharvested plots in DecAID for the ponderosa pine/Douglas-fir habitat

dry grand fir PAGs used in this analysis. Data for the moist grand fir PAG was also included. 

The moist grand fir PAG occurs on approximately 1,400 acres within the project area. 

Information is displayed for all snags greater than 10 inches dbh. Alternative 1 displays

DecAID predicts the following species will use ponderosa pine/Douglas-fir large tree vegetation: 

black-backed woodpecker, flammulated owl, northern flicker, white-headed woodpecker, 

pileated woodpecker, pygmy nuthatch, red-naped sapsucker, and Williamson’s sapsucker. 

Available information in DecAID on snag densities by species is limited and shown in Tables 70 

and 71 for the white-headed woodpecker and pileated woodpecker. Refer to the Primary Cavity 

Excavator section above for more information on white-headed and pileated woodpeckers. 

In this project area, the large snags in stands that are included in the dry grand fir PAG provide 

habitat consistent with large snags in the ponderosa pine/Douglas-fir habitat type described in 

DecAID because these stands are relatively dry and tend to have natural fire regimes that favor 

retention of early and mid seral fire tolerant species rather than late seral fire intolerant species. 

On the dry grand fir sites, the largest trees and snags are usually a mix of ponderosa pine, 

Douglas-fir, and larch, while the grand fir on these sites is more commonly present in the 

understory and mid-story layers as small or medium sized trees and snags. For this reason, the

snag counts for snags greater than 20 inches dbh in the dry grand fir PAG listed in Table 68 is 

included in the count for existing snag density in the ponderosa pine/Douglas-fir habitat type. 

The difference between the snag count in Tables 67 and 68 in the dry grand fir PAG is applied 

toward the count for existing snag density in the East Side Mixed Conifer habitat type. The 

tolerance levels for snags greater than 10 inches dbh includes both snags less than 20 inches dbh 

and snags greater than 20inches dbh. 

Using the rationale and methods stated, it has been determined that the existing condition is 

providing habitat at the 50 percent tolerance level in snags greater than 10 inches dbh for the 

white-headed woodpecker. For snags greater than 20 inches dbh, habitat is being provided at the 

30 percent tolerance level. 

For the pileated woodpecker in the ponderosa pine/Douglas-fir habitat type large tree structure 

DecAID data shows a needed snag density of 30.4 snags per acre for the 50 percent tolerance 

level for all snags over 10inches dbh or at 7.6 snags per acre in the greater than 20 inches dbh 

size class. Within this project area neither of these snag densities currently exist, so habitat is not 

being provided at the 50 percent tolerance level. Data is not available in DecAID for a 30 

percent tolerance level for this species within this habitat type. DecAID advises that the data for 

the pileated woodpecker includes plots on mixed conifer sites. 

DecAID predicts the following species would use snags among live eastside mixed conifer 

vegetation: American marten, long-legged myotis, pileated woodpecker, silver-haired bat, and 

white-headed woodpecker. DecAID also predicts that the following species would use snags in 

ponderosa pine/Douglas-fir large tree vegetation type: black-backed woodpecker, flammulated 

owl, northern flicker, white-headed woodpecker, pileated woodpecker, pygmy nuthatch, rednaped sapsucker, and Williamson’s sapsucker. The range of small snag densities used varied 

from a low of 0.3 snags per acre greater than or equal to 9.85 inches dbh at the 30 percent 

tolerance level for the white-headed woodpecker to a high of 56.4 snags per acre greater than or 

equal to 9.85 inches dbh at the 50 percent tolerance level for the silver-haired bat. The range of 

large snag densities used varied from a low of 0.0 snags per acre greater than or equal to 19.7 

inches at the 30 percent tolerance level for the white-headed woodpecker to a high of 16.8 snags 

per acre greater than or equal to 19.7 inches dbh at the 50 percent tolerance level for the silverhaired bat (USDA 2006). 

The Forest Plan standards and guidelines for snags specify that across the Ochoco National 

Forest, snags must meet an average of 47 percent of biological potential. The Eastside Screens 

amendment requires managing snags at 100 percent of maximum potential for primary cavity 

excavators, which is a minimum of 2.25 snags per acre (Thomas 1979). Viable Ecosystem 

Management Guide levels for snags were agreed upon with the Regional Office to meet the 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 211 

amendment standards and guidelines, except that snags would not be managed below a minimum 

of 2.25 snags per acre (USDA Forest Service 1997). The work by Thomas has been challenged 

by Bull and others. Bull et al. (1997) states current direction for providing wildlife habitat on 

public forest lands does not reflect the new information available which suggests that to fully 

meet the needs of wildlife, additional snags and habitat are required for foraging, denning, 

nesting, and roosting. Rose et al. (2001) stated that several major lessons have been learned in 

the period 1979 to 1999 that have tested critical assumptions of earlier management advisory 

models, including some assumptions used to develop Forest Plan standards and guidelines. 

Some assumptions include: (1) calculation of numbers of snags required by woodpeckers based 

on assessing their “biological (population) potential” is a flawed technique, (2) empirical studies 

are suggesting that snag numbers in areas used and selected by some wildlife species are far 

higher than those calculated by this technique, and (3) numbers and sizes (inches dbh) of snags 

used and selected by secondary cavity nesters often exceed those of primary excavators (Rose et 

al. 2001). 

This suggests that managing for 100 percent population levels of primary excavators may not 

represent the most current knowledge of managing for cavity nesters and that these snag levels, 

under certain conditions, may not be adequate for some species. In addition, the current 

direction provides recommendations for green stands only when studies show that cavity-nesting 

birds require higher snag densities in post-fire conditions versus green stands for nesting and 

productivity. This is likely due to cavity nesting birds requiring more snags for foraging, cover, 

and protection from predators in post-fire environments. 

The use of DecAID is a culmination of the most recent science and data available. As stated by 

Rose et al. (2001), DecAID is based on a thorough review of the literature, available research 

and inventory data, and expert judgment. Information in DecAID will be compared to the Viable 

Ecosystem Management Guide guidelines for this project. 

Other research regarding historical snag densities were reviewed to compare with information 

found within DecAID and prescribed retention levels. Harrod et al. (1998) estimated historical 

snag densities in ponderosa pine dominated dry forests. Estimated snag densities greater than 6 

inches dbh ranged from 5.9 to 14.1 per acre in pre-European settlement landscapes. Agee (2002) 

estimated lower snag densities than Harrod et al. for the ponderosa pine/Douglas-fir forest series 

by estimating number of trees in 0.1 hectare clumps of 16 age classes and assuming that the 

oldest patch is killed by insects every 25 years. Agee (2002) assumed fire helped to decompose 

snag patches and after 5 fires at 10-year intervals, snags would be completely consumed. As a 

result, historical snag density was estimated at 2 snags per acre. Results from regional studies in 

eastern Washington and Oregon (all ownerships) by Ohmann and Waddell (2002) suggest there 

are currently 2.025 total snags per acre greater than 10 inches dbh of which 0.405 snags were 

greater than 20 inches dbh. 

Snag densities reported by Harrod et al. are within the 80% tolerance level range, and Agee are 

within the 50% tolerance level range for the wildlife data and below the 30% tolerance level for 

inventory data of those reported in DecAID for ponderosa pine/Douglas-fir habitat types for 

large trees. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 212 

Retention levels were also compared with the Region 6 Interim Old Growth Definitions to 

determine if old-growth characteristics would be retained following harvest. The standard for 

meeting old-growth conditions in this document for the ponderosa pine series was that there 

needed to be 3 snags per acre greater than 14 inches dbh and/or 10 percent of the live trees in the 

stand containing “spire tops” (partially dead tops). For the Douglas-fir series, the standard was 1 

snag per acre 12 inches or greater dbh. 

Logs are an important component on the landscape. They provide organic and inorganic 

nutrients in soil development, provide microhabitats for invertebrates, plants, amphibians, and 

other small vertebrates, and provide structure for riparian associated species in streams and 

ponds. It has been shown that size, distribution, and orientation may be more important than 

tonnage or volume. Small logs provide escape cover or shelter for small species. It is still 

unknown what levels of down woody material are needed to provide quality habitat for 

associated species. Larger sized logs are also used more and by more species than smaller logs. 

(Bull et al. 1997). Log levels are prescribed in the Eastside Screens and are presented in Table 

72.

The project area has had a long history of activities that resulted in the removal of snags and 

logs. Primarily, past timber harvest and firewood cutting have resulted in lower numbers of 

downed logs than what is desired. No specific data was collected for down wood, although 

knowledge of the area indicates that downed wood levels are beginning to increase as a result of 

snags beginning to fall both within and outside the Hash Rock fire perimeter. 

Environmental Consequences 

Alternative 1 

The no action alternative would retain all existing snags in the project area except those that 

would be removed by ongoing programs of work such and recreational site and highway 

maintenance operations. At the watershed scale, snags would be retained at the levels shown in 

Tables 67 and 68. 

Alternatives 2, 4, and 5 

No dead trees would be removed, with the exception of those that are deemed to be hazard trees. 

This project does not propose to harvest snags, so the amount of snags present within the project 

area should not be substantially altered by commercial harvest. Prescribed burning may alter 

snag abundance as described above, but fire effects are not expected to alter snag densities 

enough to affect the percent tolerance for species evaluated under DecAID. The project is not 

expected to reduce the habitat tolerance level for any species for which habitat is currently being 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 213 

provided due to use of Design Elements (see Chapter 2) intended to minimize loss of snags 

during burning operations. At the watershed scale, the percent of the area with no snags will not 

change (Table 69). There would be a negligible reduction in the percent of the area that contains 

greater than 0 snags per acre. This reduction would occur as a result of hazard reduction in areas 

such as around landings and equipment fueling areas. 

No removal of existing down logs are proposed under the action alternatives. However, there is 

potential for incidental effects to species that use down logs, especially in units that are harvested

with ground-based equipment, have grapple piling, include road construction, or include 

underburning. Individual logs may be moved or broken during harvest or road construction 

activities or may be consumed during prescribed burning operations. Existing levels are 

expected to increase in the future across the project area as standing trees and existing snags fall. 

Within the areas proposed for harvest (up to 6,172 acres), green trees would be removed that 

could have otherwise potentially fallen and become downed wood. This has the potential of 

affecting accumulations of down wood in the future, although the prescribed retention levels 

would retain sufficient numbers of trees to provide down wood recruitment in the future (Table 

73). Precommercial thinning would promote the development of larger trees and thus the 

potential for long-term recruitment of large down wood. 

Alternative 3 

No dead trees or down logs would be removed, with the exception of those trees that are deemed 

to be hazard trees. This project does not propose to cut snags, so the amount of snags present 

within the project area should not be substantially altered. There would be no commercial 

harvest operations or road construction, so there would be no direct effects to species that use 

down wood. Prescribed burning may alter snag abundance as described above, but fire effects 

are not expected to alter snag densities enough to affect the percent tolerance for species 

evaluated under DecAID. The project is not expected to reduce the habitat tolerance level for 

any species for which habitat is currently being provided due to use of Design Elements (see 

Chapter 2) intended to minimize loss of snags during burning operations. 

Cumulative Effects 

Refer the cumulative effects discussion for Primary Cavity Excavators for more detailed 

information on past, present, and reasonably foreseeable activities that may affect or continue to 

have effects on species associated with snag habitat. Recently, the Cougar Salvage was 

implemented in the Marks Creek Watershed. That project removed approximately 595 dead 

trees in scattered patches on a total of 52 acres. These patches occurred in 37 locations and 

ranged from 1 to 5 acres each. Snag retention was applied as described above and displayed in 

Table 73.

Actual retention levels varied within harvest locations although all locations met or exceeded 

prescribed retention levels. No retention levels are described for moist grand fir and xeric pine 

PAGs because there was no harvest proposed under the Cougar Salvage Project. The largest 

harvest area is 5 acres with the majority of locations being less than 1 acre. The Forest Plan 

direction of providing snag habitat on a 40-acre area was met on this project. The Spears project 

when considered along with past, present, and reasonably foreseeable actions (including Cougar 

Salvage) meets Forest Plan standards for snags and down wood retention. 

There are not any other timber sales planned for the project area. Firewood gathering is expected 

to continue to reduce snag and downed wood levels in close proximity to open roads. Prescribed 

burning, ground-based timber operations, and grapple piling in the action alternatives may 

combine to increase accessibility for cross country travel which could exacerbate the loss of 

snags to firewood cutting, and may alter the abundance and distribution of down wood. 

Connective Corridors 

Affected Environment 

Connective corridors have been identified to meet the requirements of the Regional Forester’s 

Plan Amendment 2 (see Map 17). There are at least two connective corridors between all 

allocated old-growth areas and LOS stands larger than 100 acres. Connective corridors also link 

to allocated old-growth areas or LOS stands in adjacent watersheds. The connections from east 

to west through the project area cross U.S. Highway 26. 

Alternative 1 

This alternative would not treat within mapped connective corridors. The structural complexity 

and canopy closure within mapped connective corridors would be retained. On mesic sites, the 

abundance of snags and down logs and the development of multiple canopy layers would 

continue on the current trend. On drier sites, large structure ponderosa pine and larch would 

decline in vigor due to competition from the developing understory, resulting in a gradual loss of 

large live tree habitat and an increase in large snag habitat. 

This alternative treats 0 acres in connective corridors. This alternative retains existing structural

character, visual cover, and climatic moderation at least in the short term. 

Alternative 2 

This alternative includes 787 acres of commercial harvest and 535 acres of precommercial 

thinning within connective corridors. Prescribed burning of natural fuels outside of thinning 

units would occur within connective corridors on 645 acres. Within these areas, the structural 

complexity and canopy closure within mapped connective corridors would be reduced in the 

short term. It is anticipated that the level of retention post treatment would still provide adequate

cover and structure to facilitate travel by most species that would use these corridors. Some 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 215 

species that select for open forest conditions may find the habitat more favorable after treatment. 

However, treated habitat within the corridors may be less desirable for species that have limited 

mobility, that are vulnerable to predation, or that are sensitive to climatic conditions, at least in 

the short term. Where these activities occur within young stands, thinning designed to promote 

development of large trees would likely improve habitat conditions within the corridors in the 

long term. 

This alternative treats 1,966 acres in connective corridors. This alternative alters existing 

structural character and canopy cover, but improves resilience on 56 percent of the area within 

mapped connective corridors in the project area. 

Alternative 3 

This alternative includes 1,026 acres of precommercial thinning within connective corridors. 

Prescribed burning of natural fuels outside of thinning units would occur within connective 

corridors on 610 acres. Within these units the canopy closure within mapped connective 

corridors would be reduced in the short term. The level of retention post treatment would still 

provide adequate cover and structure to facilitate travel by most species that would use these 

corridors. These activities occur within young stands or understory trees only. Thinning 

designed to promote development of large trees would likely improve habitat conditions within 

the corridors in the long term. 

This alternative treats 1,636 acres in connective corridors. This alternative alters existing 

structural character and canopy cover, but improves resilience on 47 percent of the area within 

connective corridors in the project area. 

Alternative 4 

This alternative includes 700 acres of commercial harvest and 611 acres of precommercial 

thinning within connective corridors. Prescribed burning of natural fuels outside of thinning 

units would occur within connective corridors on 618 acres. Within these areas the structural 

complexity and canopy closure within mapped connective corridors would be reduced in the 

short term. It is anticipated that the level of retention post treatment would still provide adequate

cover and structure to facilitate travel by most species that would use these corridors. Some 

species that select for open forest conditions may find the habitat more favorable after treatment. 

However, treated habitat within the corridors may be less desirable for species that have limited 

mobility, that are vulnerable to predation, or that are sensitive to climatic conditions, at least in 

the short term. Where these treatments occur within young stands, thinning designed to promote 

development of large trees would likely improve habitat conditions within the corridors in the 

long term. 

This alternative treats 1,929 acres in connective corridors. This alternative alters existing 

structural character, visual cover, and climatic moderation, but improves resilience on 25 percent 

of existing LOS stands and on 55 percent of the area within mapped connective corridors in the 

project area. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 216 

Alternative 5 

This alternative includes 382 acres of commercial harvest and 883 acres of precommercial 

thinning within connective corridors. Prescribed burning of natural fuels outside of thinning 

units would occur within connective corridors on 320 acres. Due to the modified prescription 

included in this alternative for units within mapped connective corridors it is expected that 

although canopy closure would be reduced in the short term, the level of retention post treatment 

should still provide adequate cover and structure to facilitate travel by most species that would 

use these corridors. These treatments occur within young stands or understory trees only. 

Thinning designed to promote development of large trees would likely improve habitat 

conditions within the corridors in the long term. 

This alternative treats 1,585 acres in connective corridors. This alternative alters existing 

structural character and reduces canopy cover, but improves resilience on 45 percent of the 

connective corridors in the project area. 

Cumulative Effects 

There are no ongoing or reasonable foreseeable activities within the project area that would alter 

connective corridors. The effects of past harvest and other activities were considered when 

identifying connective corridors. 

Neotropical Birds 

Affected Environment 

This section addresses the effects of the alternatives on neotropical migratory birds described in 

the Partners In Flight - Northern Rocky Mountains Bird Conservation Plan. This conservation 

plan identifies priority habitats and focal species by subprovince. The Ochoco National Forest is 

within the Blue Mountains Subprovince. Table 74 lists the habitats and species for the Blue 

Mountains Subprovince. The existing condition for neotropical birds is addressed by looking at 

focal species that represent communities of birds that occupy priority habitats. Current 

conditions are described in comparison to estimates of the historic abundance of habitat. 

Table 74. Blue Mountains Subprovince priority habitats and focal species.

Nine of the seventeen species listed were analyzed using the data derived from the Viable 

Ecosystems Model. White-headed woodpecker was analyzed and is described above in the 

Primary Cavity Excavators section. In addition, gray flycatcher was analyzed as a surrogate for 

steppe shrublands (in lieu of vesper sparrow), and black-backed woodpecker was analyzed as an 

indicator for mature true fir forest conditions in Mesic Mixed Conifer priority habitat. The 

existing amount of priority habitat has been compared to the desired range of habitat identified as 

the HRV. This allows a comparison between what exists today compared to the balance of 

conditions that may have existed historically. Of the ten species discussed in this section, seven 

are currently above the minimum amount of habitat abundance and three are below. Generally, 

there is a relative shortage of habitat for those species associated with open forest conditions. 

These trends are primarily the result of past management practices and fire suppression activities. 

Table 75 displays the habitat amounts in the project area. Species whose habitat is currently 

below historic abundance are: chipping sparrow, olive-sided flycatcher, and gray flycatcher. 

Species whose habitat is currently within historic abundance are: flammulated owl, Lewis’ 

woodpecker, varied thrush, MacGillivray’s warbler, hermit thrush, and black-backed 

woodpecker. A species with habitat currently above the historic range is the Townsend’s 

warbler, which favors dense forest conditions with an abundance of fir. 

Species that require specialized habitats such as riparian vegetation, meadows, hollow trees, 

aspen, or alpine cannot be analyzed this way (based on forest structural/seral stages). None of 

the alternatives include reducing shrub or meadow habitat. The action alternatives include 

restoration activities for aspen stands and prescribed burning may result in restoration or 

alteration of upland shrub and grassland habitats.

Environmental Consequences 

Alternative 1 

This alternative would continue to perpetuate the abundance of wildlife species associated with 

dense forests having true fir and Douglas-fir understories. The no action alternative would not 

directly change the existing acres of habitat. Under this alternative there would be a continued 

decline in habitat abundance for all species that select open forest and early seral conditions as 

denser, mid to late seral conditions continue to develop. In the long-term, Alternative 1 results in 

the least amount of habitat for species that select for open forest or early seral conditions. In the

long-term, this alternative would result in the most habitat of all the alternatives for these species

associated with denser, mid to late seral conditions. This alternative does not propose any 

treatments that would directly modify the existing amount of habitat therefore post treatment 

acres equals existing acres. Habitat would compare to HRV as described above and displayed in 

Table 75 in the short term. 

The red-eyed vireo, veery, and willow flycatcher are associated with riparian woodland and 

shrub plant communities. These habitats exist within the project area, but are small in size and 

fragmented. These species may be present and utilizing the habitats as available. The no action 

alternative would retain the current trends in displacement of riparian vegetation due to 

encroachment by young conifers. The red-naped sapsucker is a bird that uses aspen dominated 

vegetation and riparian woodlands almost similar to the vireo, veery, and willow flycatcher. The 

no action alternative does not propose aspen restoration activities involving thinning of conifers 

which are competing with aspen. 

This alternative maintains habitat for species that select for dense forest conditions and continues 

the decline in habitat conditions for species that use open forest conditions until one or more 

disturbance events (insects or fire) create open conditions in the future. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 219 

Direct and Indirect Effects Common to Alternatives 2, 3, 4, and 5 

Of the remaining species listed in Table 74, the upland sandpiper is discussed below in the 

threatened, endangered, and sensitive species section of this report. This Region 6 Regional 

Forester’s Sensitive Species and its habitat are not affected by the project proposals as they 

occupy expansive wetland habitats which do not occur in the project area. The vesper sparrow 

inhabits steppe shrublands found at lower elevations and are not present within forested habitats 

or in the project area. The gray-crowned rosy finch inhabits alpine habitats that do not occur 

within this project area. Therefore, the proposed activities would have no effect to these species 

or their habitats. 

Measures prescribed to restrict activities within nesting seasons for goshawk and other raptors 

would result in reduced disturbance to nesting birds where their home ranges overlap with these 

areas. Some of the harvest, thinning and burning activities would be scheduled outside of the 

nesting season and would not result in disturbance to nesting birds. However, a portion of the 

project work would occur during the nesting season and some individuals would likely be 

impacted by management activities. Since most migratory birds occupy relatively small nesting 

season home ranges and are present in relatively large numbers, it is expected that suitable 

habitat outside of active treatment units will provide alternate cover for birds that are displaced 

during activities. The area outside of active treatment units will also provide source populations 

for reoccupation of areas after treatment activities are completed. Birds that are disturbed early 

in the nesting season may move out of the treatment area during operations and may re-nest later, 

or outside of the area of activity. In some cases, habitat outside of the unit may be limiting or 

fully occupied, in which case the displaced birds may become non-reproductive during the year 

of operation. These are short-term impacts to individual birds or pairs of birds. This is a tradeoff under the action alternatives for (1) the long term benefits of increasing the amount of habitat 

for the focal species (and the communities they represent) that are currently below the HRV, (2) 

the restoration of habitat for species that utilize herbaceous and shrubby vegetation, and (3) the 

protection of habitat against risk of future large scale or high intensity disturbance. The project 

also proposes treatments to promote the longevity, vigor, and extent of riparian hardwood 

habitats and the development or retention of stands of large diameter live pine. These treatments 

are consistent with the goals and objectives for these habitats as listed in the Partners In Flight, 

Landbird Conservation Strategy for the Northern Rocky Mountains (Altman 2000). 

Alternative 2 

This alternative would treat 16,942 acres. Some of this treatment would occur in habitat for 

neotropical birds during the nesting season and potentially impact nesting birds. This alternative 

results in increases in habitat for species that select for open forest and early seral conditions due

to stand density reduction and the favoring of early seral species. The amount of habitat relative 

to HRV changes to within the historic range for chipping sparrow, olive-sided flycatcher, and 

Townsend’s warbler due to increases in open forest and decreases in dense forest conditions. 

However, the amount of habitat moves to below the minimum for MacGillivray’s warblers, due 

to thinning of understory vegetation in moist grand fir sites. This effect on MacGillivray’s 

warblers should be short term as thick patches of understory vegetation should recover relatively 

quickly on these mesic sites, especially in riparian areas and other seasonally moist areas. 
Chapter 3 - Affected Environment and Environmental Consequences

Habitat for gray flycatcher moves further below the low end of the HRV, primarily due to 

reduction in small tree and tall shrub structure on ponderosa pine and western juniper sites. The 

extent and duration of impacts on gray flycatcher nesting habitat will depend on how thoroughly 

small tree and shrub structure (ground fuels) are removed from potential habitat and subsequent 

maintenance treatments, such as repeated underburning. Past experience indicates that 

approximately 40-70 percent of the surface area within prescribed fire units is burned. As shrub 

cover may be reduced by scorch as well as consumption, it is expected that upland shrub habitat 

will be reduced on more than 40-70 percent of the area treated with prescribed burning, at least 

in the short term. There is potential for treatments to promote the development of gray 

flycatcher habitat where upland shrub regeneration is promoted and tall shrubs are allowed to 

develop after the initial treatments on xeric sites (dry pine and western juniper PAGs). In the 

long-term, Alternative 2 results in the greatest amount of habitat for all open forest and upland 

shrub species, as well as those that select for large tree size. Activities would cause a reduction 

in the amount of habitat for species that select for denser forests or late-seral conditions.

This alternative would alter the current trend in displacement of riparian vegetation due to 

encroachment by young conifers in the portions of this habitat type where prescribed fire or 

thinning occur. This would result in a beneficial effect to species associated with riparian 

woodland and shrub plant communities (red-eyed vireo, veery, and willow flycatcher). This 

alternative also proposes aspen restoration activities involving thinning of conifers which are 

competing with aspen clones. This would result in a beneficial effect to species associated with 

aspen dominated vegetation, such as red-naped and Williamson’s sapsuckers. 

This alternative reduces habitat for species that select for dense forest conditions and reverses the 

decline in habitat conditions for species that use open forest conditions, riparian hardwoods, and 

upland shrubs. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 221 

Alternative 3 

This alternative would treat 15,501 acres. Some of this treatment would occur in habitat for 

neotropical birds during the nesting season and potentially impact nesting birds. This alternative 

results in more habitat for species that select for open forest and early-seral conditions due to 

stand density reduction and the favoring of early seral species. As described above for 

Alternative 2, the amount of habitat relative to HRV changes to within the historic range for 

chipping sparrow and olive-sided flycatcher. However, habitat for Townsend’s warbler remains 

above the historic range, and moves to below the minimum for MacGillivray’s warbler. This 

effect on MacGillivray’s warblers should be short term as thick patches of understory vegetation 

should recover rapidly on these mesic sites, especially in riparian areas and other seasonally 

moist areas. Habitat for gray flycatcher moves further below the low end of the HRV, due to 

reduction in small tree and tall shrub structure on ponderosa pine and western juniper sites. In 

the long term, Alternative 3 results in the least (among the action alternatives) acres of habitat for

open forest species. This alternative promotes habitat for open forest species as well as those 

that select for large tree size, but not as much as in alternatives with commercial harvest. 

Proposed treatments would cause a short-term reduction in the amount of habitat for species that 

select for denser forests or later seral conditions, but canopy closure is expected to recover within 

15 to 20 years on relatively mesic sites. 

This alternative would alter the current trend in displacement of riparian vegetation due to

Cumulative Effects 

Regeneration harvest activities have occurred on 7,563 acres in the project area in the last 30 to 

35 years. Much of this harvest history resulted in a reduction of large pine and other LOS stands. 

Since the early 1990’s the emphasis has shifted from removal of large pine to re-establishment of 

large pine and larch, and other single-strata LOS stands. Forested areas would continue to 

managed to increase the abundance of open, single-storied ponderosa pine dominated stands on 

dry sites. This is the type of forest structure thought to be the historic condition on the majority 

of ponderosa pine sites. Forests would continue to managed to increase the abundance of LOS in 

both single and multiple layer structural classes on more mesic sites. This management trend is 

likely to continue until the multi-strata LOS and single-strata LOS is within the HRV that has 

been defined for this project area. This process would reduce the amount of habitat available for 

species that prefer dense forest canopy, while increasing the amount of habitat available for 

species that select more open stands. Thinning of stands with relatively small trees should 

promote the development of large tree habitat in the future. The recruitment of large trees and 

large snags would contribute potential habitat for species that nest high in tall trees, that require 

large branches, or large snags to accommodate appropriately sized cavity nests or colonial roosts. 

Ultimately, all species habitat would move toward an abundance and distribution that is thought 

to be within the historic range of variability based on site potential within the project area. 

Riparian planting and hardwood protection has been implemented at various locations 

throughout the project area. These actions have lead to improved riparian hardwood habitat in 

many areas. At the same time, elk populations have continued to climb and livestock grazing has 

continued to occur. The combined grazing and browsing pressure from wild and domestic 

ungulates has limited the extent and structure of riparian habitat in some areas. 

Threatened, Endangered, and Sensitive Species 

Affected Environment 

There are no endangered species known or expected to occur on the Ochoco National Forest. 

The northern bald eagle, a threatened species, is known to occur within the project area. 

The Canada lynx, a threatened species, is not expected to occur in the project area or on the 

Ochoco National Forest. Canada lynx occupies boreal forests where subalpine fir is common 

and lodgepole pine is a seral species. Their primary prey is snowshoe hare. Based on 

implementation of habitat descriptions contained in the second edition of the Canada Lynx 

Conservation Assessment and Strategy (Ruediger et al. 2000), there is inadequate primary 

vegetation to constitute any Lynx Analysis Units (LAUs) on the Ochoco National Forest. There 

are no other LAUs within 40 kilometers of the Ochoco National Forest; thus, no Key Linkage 

Areas were identified. On May 29, 2001 the Ochoco National Forest received concurrence from 

the U.S. Fish and Wildlife Service that implementation of any activities contained within the 

Ochoco National Forest Land and Resource Management Plan, as amended, is “not likely to 

adversely affect the Canada lynx outside of an existing LAU” (McMaster 2001). Because 

habitat has been determined to not be present on the Forest in a quantity sufficient to apply the 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 225 

standards and guidelines contained in the LCAS, and the completion of informal consultation 

with the U.S. Fish and Wildlife Service is contained in a separate document (McMaster 2001), 

the species will not be discussed further. 

here. 

Of the eight wildlife species on the Regional Forester’s list that are documented or suspected to 

occur on the Ochoco National Forest, four sensitive species have potential or suitable habitat 

within the project area. These species are: California wolverine (Gulo gulo), gray flycatcher 

(Empidonax wrightii), bufflehead (Bucephala albeola), and tricolored blackbird (Agelaius 

tricolor). 

The other four sensitive species do not have potential habitat within the project area and the 

proposed alternatives would have no effects to these species. They are: Peregrine falcon (Falco 

peregrinus anatum), upland sandpiper (Bartramia longicauda), western sage grouse 

(Centrocercus urophasiuanus), and pygmy rabbit (Brachylagus idahoensis). 

Peregrine falcon nests on sheer rock cliffs with horizontal ledges or caves and forages over a 

variety of habitats. Birds are a primary source of prey for this species. The nearest suitable 

nesting habitat for this species is in the adjacent Mill and McKay Creek watersheds and on the 

cliffs that overlook Ochoco Reservoir. These sites are currently occupied by prairie falcons. 

Nesting by peregrine falcons has not been confirmed on the Lookout Mountain Ranger District. 

There is no suitable nesting habitat for this species in the project area; this project would not 

impact nesting habitat and is not expected to affect individual members of this species. For these 

reasons, this project would have no impact on peregrine falcons. 

Upland sandpiper occupies large open wetlands, marshes, and wet meadow habitats. The nearest 

confirmed nesting area is in Big Summit Prairie, approximately 8 miles east of the project area. 

There is no suitable nesting habitat for this species in the project area; this project would not 

impact nesting habitat and is not expected to affect individual members of this species. For these 

reasons, this project would have no impact on upland sandpipers. 

Western sage grouse occupies open arid shrub steppe and grassland habitat in relatively treeless 

environments. They feed on forbs and insects when they are available, but sustain themselves on 

sagebrush leaves in the winter. There is no suitable nesting habitat for this species in the project 

area; this project would not impact nesting habitat and is not expected to affect individual 

members of this species. For these reasons, this project would have no impact on western sage 

grouse. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 226 

Pygmy rabbit occupies sagebrush habitats with deep loose soil conditions suitable for excavation 

and maintenance of burrows. Although they feed on grasses and forbs seasonally, big sagebrush 

is their primary food source. There is no suitable denning habitat for this species in the project 

area; this project would not impact reproductive habitat and is not expected to affect individual 

members of this species. For these reasons, this project would have no impact on pygmy rabbits. 

Northern Bald Eagle 

There are no known nest sites or essential habitat within the project area for bald eagles. The 

nearest known bald eagle nest sites are approximately 5 miles southwest and 6 miles southeast of 

the project boundary. Eagles have been observed foraging along Marks Creek and east of the 

project area along Ochoco Creek. There are large trees in the project area that may serve as 

perch trees, roost sites, or potential future nest sites. Improved nesting success and a population 

increase lead to a 1999 proposal to delist the bald eagle as a threatened species (Marshall et al. 

2003). 

California Wolverine 

There are no known California wolverine dens within the project area. Wolverines have been 

recorded 3 miles north of the project area in 1981, 1983, and 1994. Wolverine have also been 

recorded in and within 2 miles of the south end of the project area in 1979 (three locations) and 

1980. Wolverines are thought to avoid areas with dense young regenerating forest (Csuti et al. 

1997), large open areas, and areas with high road density and human use (Verts and Carraway 

1998 and Rowland et al. 2002). Wolverines are wide ranging and persist at extremely low 

population densities, making detection difficult. It is uncertain whether wolverines occur in 

Oregon as a self-maintaining population, or if the occasional sightings in this area represent long 

distance foraging or dispersal of populations centered farther to the north. The wolverine is a 

U.S. Fish and Wildlife Service Species of Concern and is classified as S2-OR (imperiled in 

Oregon) in the Natural Heritage Program ranking (Csuti et al. 1997). 

Gray Flycatcher 

Gray flycatchers have been documented on Ochoco National Forest with confirmed breeding on 

the Crooked River National Grassland and in the Maury Mountains/Camp Creek area. The 

Oregon Breeding Bird Atlas (Adamus et al. 2001) mapped an area, that includes the Marks 

Creek Watershed, as possible breeding habitat. Gray flycatchers nest in tall shrubs or small trees 

in very open areas or on the edges of shrub steppe and woodland ecotones. Breeding bird survey 

data indicate an increasing trend in gray flycatcher populations in Oregon, and Eastern Oregon 

has some of the highest population densities in the species’ breeding range (Marshall et al. 

2003). The species currently holds a ranking by the Natural Heritage program as N3B - either 

rare throughout its range or found locally in a restricted range. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 227 

Bufflehead 

Bufflehead are a species of cavity nesting ducks that nest along shorelines of mountain lakes. 

Within the project area, buffleheads are most likely to be seen on private lakes or ponds, or in 

stock watering or borrow pit ponds during migration. Bufflehead have been seen on the Lookout 

Mountain Ranger District using ponds as migratory stop over sites. Because the only water-body 

of sufficient size to serve as a potential nesting area in the project area is surrounded by privately

owned residential property, it is unlikely that bufflehead will nest in this project area. There are 

no confirmed nesting records in Crook County, but there have been broods recorded in 

Deschutes County (Marshall et al. 2003). The Oregon breeding population is considered 

sensitive in Oregon because of small breeding population size, limited nesting structure, potential 

for disturbance due to recreational use, and potential for loss of nest sites through snag removal 

(Marshall et al. 2003). The species currently holds rankings in Oregon as SU sensitive 

(undetermined status) and by the Natural Heritage program as S2B-OR Imperiled in Oregon. 

Tricolored Blackbird 

Tricolored blackbirds are a colonial nesting species that prefer to nest in emergent vegetation 

such as cattails or tall sedges or in thickets of willows or other shrubs. Their breeding 

distribution in Oregon is unpredictable from year to year, but is often found in mixed flocks 

along with red-winged blackbirds (Csuti 1997). Very small breeding colonies have been 

confirmed in northwestern Crook County. The Oregon population, which represents only 1% of 

the total population of this species, declined during the 1980’s due to elimination of habitat, 

burning, plowing, loss of food source, pesticides, human disturbance (traffic), small colony size, 

and shifting local populations. The species currently holds rankings in Oregon as SP sensitive 

(peripheral or naturally rare) and by the Natural Heritage program as G3 Vulnerable - either rare 

throughout its range or found locally in a restricted range. 

Environmental Consequences 

Northern Bald Eagle 

Alternative 1 

This alternative would not directly alter habitat for bald eagles in the short term, but may lead to 

increased mortality of large ponderosa pine in the future which may reduce potential future 

nesting habitat. However, the lack of high quality foraging habitat (large water bodies with 

abundant fish and waterfowl resources) limits the potential of this project area to contribute to 

essential habitat for this species. There are no cumulative effects for the no action alternative, as

there are no action related effects to be combined with effects of past, present and reasonably 

foreseeable actions. Because this alternative may contribute to changing conditions which could 

result in future loss of nesting sites, this alternative is determined to be may affect, but not likely 

to adversely affect for bald eagles. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 228 

Alternative 2 

This alternative would improve habitat for bald eagles by creating more open forest conditions 

which would make prey and carrion more accessible. However, this alternative may also have 

some potential to result in disturbance to roosting or foraging eagles. This alternative is expected 

to increase longevity of large, live ponderosa pine which would maintain potential future nesting 

habitat. However, the lack of high quality foraging habitat limits the potential of this project area

to contribute to essential habitat for this species. Because this alternative has potential to 

improve the longevity of potential nest trees and potential to disturb individuals, the effect of this

alternative is may affect, but not likely to adversely affect for bald eagles. 

Alternative 3 

This alternative would improve habitat in the short term by creating slightly more open forest 

conditions which would make prey and carrion more accessible. However, this alternative may 

also have some potential to result in disturbance to roosting or foraging eagles. This alternative 

would lead to increased longevity of large, live ponderosa pine which would maintain potential 

future nesting habitat. However, the lack of high quality foraging habitat limits the potential of 

this project area to contribute to essential habitat for this species. Because this alternative has 

potential to improve the longevity of potential nest trees and potential to disturb individuals, the 

effect of this alternative is may affect, but not likely to adversely affect for bald eagles. 

Alternative 4 

This alternative would improve habitat for bald eagles by creating more open forest conditions 

which would make prey and carrion more accessible, but the project may also have some 

potential to result in disturbance to roosting or foraging eagles. This alternative would lead to 

increased longevity of large, live ponderosa pine in the future which would maintain potential 

future nesting habitat. However, the lack of high quality foraging habitat limits the potential of 

this project area to contribute to essential habitat for this species. Because this alternative has 

potential to improve the longevity of potential nest trees and potential to disturb individuals, the 

effect of this alternative is may affect, but not likely to adversely affect for bald eagles. 

Alternative 5 

This alternative would improve habitat for this species by creating more open forest conditions 

which would make prey and carrion more accessible. However, this alternative may also have 

some potential to result in disturbance to roosting or foraging eagles. This alternative would lead 

to increased longevity of large live ponderosa pine in the future which would maintain potential 

future nesting habitat. However, the lack of high quality foraging habitat limits the potential of 

this project area to contribute to essential habitat for this species. Because this alternative has 

potential to improve the longevity of potential nest trees and potential to disturb individuals, the 

effect of this alternative is may affect, but not likely to adversely affect for bald eagles. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 229 

Cumulative Effects 

Past activities, ongoing projects, and reasonably foreseeable activities that could potentially 

affect bald eagles include past timber harvest, salvage sales, recreational use, agricultural 

practices, and management of fish and game. Effects from these activities are not expected to 

combine with this project to result in cumulative effects. 

The 2006 Joint Aquatic and Terrestrial Programmatic Biological Assessment (BA) for Federal 

Lands within the Deschutes Basin administered by the BLM Prineville Office and the Deschutes 

and Ochoco National Forests addresses program activities that may affect, but are not likely to 

adversely affect listed species. The BA identifies project design criteria (PDC) that should be 

used for bald eagles to streamline consultation. This project meets the PDCs for bald eagle 

nesting and roosting areas because the alternatives were designed to retain all trees greater than 

21 inches dbh and retain potential roost snags. There is no essential habitat for bald eagles 

within the project area, and the project is not inconsistent with any PDCs recommended in the 

Programmatic BA, which is consistent with the Pacific Bald Eagle Recovery Plan. For these 

reasons, the determination for this project is may affect but not likely to adversely affect for all 

action alternatives. 

California Wolverine 

Alternative 1 

This alternative would not directly alter habitat for this species. Densely forested areas would 

remain so, at least in the short term and road density would remain approximately the same as it 

is today. Overtime, patches of forage and accumulations of down wood may develop in 

conjunction with increased insect/disease infestations or fire. These features may contribute to 

future wolverine habitat by increasing food resources for big game (a primary source of carrion) 

and by providing potential denning habitat associated with down woody debris. However, due to 

the lack of remoteness (due to high levels of human activity) and the lack of high potential 

denning sites (north and northeast facing cirque basins with talus slopes), the potential for this 

project area to provide suitable habitat for denning wolverines is very limited. There are no 

cumulative effects because there are no effects from this alternative that would add to the effects 

of past, present, and reasonably foreseeable actions. Because this alternative may contribute to 

changing conditions which could result in changes in the availability of food and sites for 

denning, this alternative may impact individuals or habitat, but will not likely contribute to a 

trend towards federal listing or cause loss of viability to the population or species for wolverine. 

Alternative 2 

This alternative would alter habitat for the California wolverine. Some densely forested areas 

would be made more open, and road density would be reduced upon completion of the project. 

Over time, development of large down wood may be accelerated in stands where it is currently 

lacking. Forage availability would be increased for small mammals and big game. These 

features may contribute to wolverine habitat by increasing food resources and by promoting 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 230 

potential future denning habitat associated with large down woody debris. This alternative may 

disturb wolverines that may be moving through the project area during treatment activities. 

However, due to the lack of remoteness (due to high levels of human activity) and the lack of 

high potential denning sites (north and northeast facing cirque basins with talus slopes), the 

potential for this project area to provide suitable habitat for denning wolverines is very limited. 

Therefore, the effect of this alternative on wolverine is determined to be may impact individuals 

or habitat, but will not likely contribute to a trend towards federal listing or cause loss of viability 

to the population or species. 

Alternative 3 

This alternative would alter habitat for this species. Some densely forested areas would be made 

slightly more open, and road density would remain approximately the same as it is today. Over 

time, development of large down wood may be accelerated in stands where it is currently 

lacking. Forage availability may be increased slightly in treated stands. These features may 

contribute to wolverine habitat by increasing food resources and by promoting potential future 

denning habitat associated with large down woody debris. This alternative may disturb 

wolverines that may be moving through the area. However, due to the lack of remoteness and 

the lack of high potential denning sites, the project area only has limited potential to provide 

suitable habitat for denning wolverines. Therefore, the effect of this alternative on wolverine is 

determined to be may impact individuals or habitat, but will not likely contribute to a trend 

towards federal listing or cause loss of viability to the population or species. 

Alternative 4 

This alternative would alter habitat for the California wolverine. Some densely forested areas 

would be made more open, and road density would be reduced upon completion of the project. 

Over time, development of large down wood may be accelerated in stands where it is currently 

lacking. Forage availability would be increased for small mammals and big game. These 

features may contribute to wolverine habitat by increasing food resources and by promoting 

potential future denning habitat associated with large down woody debris. There is potential for 

project activities to cause disturbance to wolverine that may be moving through the area. 

However, due the lack of remoteness and the lack of high potential denning sites, the potential 

for this project area to provide suitable habitat for denning wolverines is very limited. Therefore, 

the effect of this alternative on wolverine is determined to be may impact individuals or habitat, 

but will not likely contribute to a trend towards federal listing or cause loss of viability to the 

population or species.

activities to cause disturbance to wolverine that may be moving through the area. However, due 

the lack of remoteness and the lack of high potential denning sites, the potential for this project 

area to provide suitable habitat for denning wolverines is very limited. Therefore, the effect of 

this alternative on wolverine is determined to be may impact individuals or habitat, but will not 

likely contribute to a trend towards federal listing or cause loss of viability to the population or 

species. 

Cumulative Effects 

Past activities, ongoing projects, and reasonably foreseeable activities that could impact 

wolverine include livestock grazing, recreational use, and big game management. Impacts from 

these activities are not expected to add to the effects from this project to result in cumulative 

effects. 

For the reasons stated above, the determination for this project is may impact individuals or 

habitat, but will not likely contribute to a trend toward federal listing for all action alternatives. 

Gray Flycatcher 

Alternative 1 

This alternative would not alter habitat for this species. Densely stocked dry forest and 

woodland areas would remain unsuitable for gray flycatchers. Overtime, large scale disturbances 

may develop which would re-set succession to an early seral stage in non-forested, juniper, and 

dry pine sites. Such events may contribute to restoring future gray flycatcher habitat by 

producing open settings and regenerating upland shrubs. However, there is also potential for 

future high intensity disturbance to promote dominance by weedy annuals such as cheat grass. If 

such species become dominant, fire regimes can change in a way which results in frequent 

reburning, which can prevent development of tall shrub structure and thus nesting habitat for 

gray flycatchers. Based on disturbance history within the project area, and vegetative responses 

observed within previous burned areas, future disturbance patterns are not expected to result in 

large scale or prolonged loss of gray flycatcher habitat. There are no cumulative effects for the 

no action alternative. Because this alternative may contribute to changing conditions which 

could result in changes in the availability of habitat for this species, this alternative may impact 

individuals or habitat, but will not likely contribute to a trend towards federal listing or cause 

loss of viability to gray flycatcher. 

Alternative 2 

This alternative would slightly alter habitat for the gray flycatcher. Some densely stocked dry 

forest and woodland areas would be thinned and/or burned. Initially, these activities are 

expected to reduce nesting structure as described in the section on Neotropical Migratory Birds. 

However, nesting habitat may be improved within treated areas on xeric sites (non-forest, 

juniper, and dry ponderosa pine PAGs) if overstory density is reduced sufficiently, and if suitable 

tall shrub nesting cover is retained. Based on previous experience with prescribed fire behavior, 

it is expected that patches of tall shrubs and occasional small trees would be retained in the post-
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 232 

fire mosaic, and that gray flycatcher habitat structure would be retained in patches distributed 

across treated areas. Therefore, the effect of this alternative on gray flycatchers is determined to 

be may impact individuals or habitat, but will not likely contribute to a trend towards federal 

listing or cause loss of viability to the population or species. 

Alternative 3 

This alternative would alter habitat for this species. Some densely stocked dry forest and 

woodland areas would be thinned and/or prescribed burned. Initially these treatments may 

reduce nesting structure as described in the section on Neotropical Migratory Birds. However, 

nesting habitat may be improved within treated areas on xeric sites (non-forest, juniper and dry 

ponderosa pine PAGs) if overstory density is reduced sufficiently, and if suitable tall shrub 

nesting cover is retained. Based on previous experience with prescribed fire behavior it is 

expected that patches of tall shrubs and occasional small trees would be retained in the post-fire 

mosaic, and that gray flycatcher habitat structure would be retained in patches distributed across 

treated areas. Therefore, the effect of this alternative on gray flycatchers is determined to be may 

impact individuals or habitat, but will not likely contribute to a trend towards federal listing or 

cause loss of viability to the population or species.

listing or cause loss of viability to the population or species. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 233 

Cumulative Effects 

Past activities, ongoing projects, and reasonably foreseeable activities that could result in impacts 

to gray flycatchers include grazing and mining. Impacts from these activities are not expected to 

add to the effects from this project and result in cumulative effects to gray flycatcher. 

The Breeding Bird Atlas (Adamus et al. 2001) indicates that this species population is presently 

increasing and that this species is widely distributed across its range. Lower elevation areas, 

below the forest boundary are the core reproductive habitats for this species. For these reasons 

and the considerations described above, the determination is may impact individuals or habitat, 

but will not likely to contribute to a trend toward federal listing for all action alternatives. 

Bufflehead 

All Alternatives 

None of the alternatives would alter habitat for this species. The alternatives would have no 

effect on this species or its habitat. Therefore, the determination for all alternatives is no impact

to bufflehead. 

Cumulative Effects 

Past activities, ongoing projects, and reasonably foreseeable activities that could impact 

bufflehead include lake shore development and recreational use. The proposed alternatives 

would not effect lake shore development and are not expected to change recreational use that 

would have an effect on bufflehead. There would be no cumulative effects to bufflehead. 

Within the project area, habitat is marginal for this species, with low likelihood of occupancy by 

nesting pairs. Project activities would not alter lake or lakeshore habitat and is not likely to 

result in disturbance to nesting pairs. For these reasons, the determination is no impact to 

bufflehead for all action alternatives 

Tricolored Blackbird 

All Alternatives 

None of the alternatives would alter habitat for this species. The alternatives would have no 

effect on this species or its habitat. Therefore, the determination for all alternatives is no impact

to bufflehead. 

Cumulative Effects 

Past activities, ongoing projects, and reasonably foreseeable activities that could impact 

tricolored blackbird include development near wetlands and recreational use. Impacts from these 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 234 

activities are not expected to add to the effects from this project. There would be no cumulative 

effects to tricolored blackbird. 

The project would not alter vegetation that would provide habitat for nesting or migrating 

tricolored blackbirds. This project would have no impact on this species or its habitat. For these 

reasons, the determination is no impact for tricolored blackbird for all alternatives. 

Elk 

Affected Environment 

Long-term records indicate that elk were absent from the Ochoco National Forest in 1936 

(Bailey 1936). This is the oldest written record of elk populations on the Forest. Anecdotal 

information indicates elk did inhabit the Forest in the mid to late 1800’s but were probably 

extirpated by over-hunting and habitat losses due to heavy grazing pressure in the early 1900’s. 

Since that time, elk populations have made steady increases in populations and are now found 

throughout the Ochoco National Forest. 

The Spears project area lies within two Oregon Department of Fish and Wildlife (ODFW) 

management zones, the Ochoco and Grizzly Game Management Units (GMUs). ODFW, in their 

state-wide “Oregon’s Elk Management Plan” established population management objectives 

(MOs) for all GMUs in the state. The population objectives for the Grizzly and Ochoco GMUs 

were 1,500 and 2,600 respectively, both of which were met in 1996 population estimates. 

ODFW population estimates for 2003 for these units were 1,500 and 4,600 respectively. The 

Ochoco GMU population peaked in 2000-2001, but has exceeded management goals each year 

form 1995 through 2003. While trend information is presented, it is important to note that many 

of the population dynamics exhibited on the Forest are affected by hunting scenarios and trends 

are not necessarily a reflection of habitat conditions. Mortality rates due to hunting may be the 

factor limiting total population. Bull/cow ratios are most significantly affected by hunting 

activities and it is hard to determine the effect from Forest management activities on this 

parameter. However, the abundance and distribution of escapement cover, the density of open 

roads, and degree of accessibility by off-highway vehicles are factors that likely affect survival 

of animals during hunting seasons. 

The Habitat Effectiveness Index (HEI) for elk was used to analyze the elk habitat condition and 

the effects of alternatives within the Spears Project Area. HEI is a measure of habitat suitability 

based on cover quality (relative abundance of marginal and satisfactory thermal cover), cover 

quantity (percent of the project area in existing cover), and open road density. The Forest Plan 

specifies goals within each of the management areas: General Forest, General Forest Winter 

Range, and Winter Range. For this analysis, visual corridors were combined into the three 

Management Areas with HEI goals, as they are not biologically distinct (i.e. elk do not know 

when they are in a visual corridor). The analysis also assumed that in General Forest 

commercial harvest in marginal cover (40-69% crown closure) would render the stand non-cover 

at least in the short term, but that precommercial thinning would retain enough canopy closure to 

maintain marginal cover. In General Forest Winter Range and Winter Range it was assumed that 

any treatment in marginal cover would result in taking the stand out of cover. This assumption is 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 235 

applied to these areas due to elevation and the prevalence of relatively dry PAGs within those 

areas (proposed activities will promote more open conditions on juniper, ponderosa pine, and 

Douglas-fir sites). The assumption was also made that any treatment in satisfactory cover (70% 

+ canopy closure) would change the stand to marginal cover at least in the short term in all three 

management areas. Values determined by the analysis, and specified in the Forest Plan are 

displayed in Tables 80-83. Table 80 displays the existing condition and Forest Plan goals. 

Tables 81, 82, and 83 display a summary of the results by alternative for General Forest, General 

Forest Winter Range, and Winter Range areas, post-treatment and after road closures are 

completed. 

The January 29, 2007, Spears Wildlife Report contains additional information on elk. 

Alternative 1 

No satisfactory cover or marginal cover would be treated under this alternative, and no roads 

would be closed. Percent cover and HEI would remain at the current levels for a period of time. 

Habitat effectiveness would continue to follow the current trend, with gradual development of 

additional cover as the canopy of untreated stands continue to close. At the same time the 

development of understory vegetation would gradually increase the risk of future loss of cover to 

fire, insects, and disease. The year-round open road density is expected to remain at 

approximately the current level. The winter open road density is expected to remain at 1.0 

miles/square mile between December 1 and May 1 with continued on-going implementation of 

the seasonal restrictions that are currently in place. 

Goals established in the Forest Plan for overall HEI would be met under this alternative. Open 

road density would remain slightly above the maximum included in the plan standards for 

General Forest. Current trends in cover and forage availability would continue. Satisfactory 

cover would not be impacted and road density would not be reduced. Elk would continue to use 

the area, but forage availability is expected to gradually decrease as the area dominated by dense 

forest cover continues to expand. Forage would return in areas where future disturbances such as 

insects, disease, or fire reduce forest canopy closure. 

Alternative 2 

Within General Forest, this alternative would reduce satisfactory cover by 895 acres, and 

decrease marginal cover by 609 acres. Total cover acres in General Forest would be reduced by 

1,504 acres, resulting in a 7 percent decrease of percent cover and no change to the cover quality 

index (an index included in the HEI analysis which represents the relative quality of cover based 

on canopy closure). Within General Forest Winter Range, this alternative would reduce 

satisfactory cover by 162 acres, and would reduce marginal cover by 742 acres. Total cover 

acres in General Forest Winter Range would be reduced by 904 acres, resulting in a 29 percent 

decrease in percent cover and no change to the cover quality index. Within Winter Range, this 

alternative would reduce satisfactory cover by 337 acres and marginal cover by 1,220 acres. 

Total cover acres in Winter Range would be reduced by 1,557 acres, resulting in a 32 percent 

decrease of percent cover and no change to the cover quality index. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 236 

Seasonal restriction on harvest, thinning, fuels and related activities would be implemented 

between December 1 and May 1 in General Forest Winter Range and in Winter Range 

allocations. 

Alternative 2 would initially increase road density in the short term (during implementation) as 

follows: General Forest 0.1 miles per square mile, General Forest Winter Range 0.2 miles per 

square mile, and Winter Range 1.1 miles per square mile. After timber and follow-up operations 

are complete, road closures would reduce road density by 0.3 mile per square mile in General 

Forest, 0.2 miles per square mile General Forest Winter Range and 0.4 miles per square mile 

Winter Range (compared to existing conditions). Combined with the cover effects described 

above, HEI would be decreased from 39.2 to 33.6 in General Forest, decreased from 45.1 to 17.5 

in General Forest Winter Range, and reduced from 53.8 to 15 in Winter Range. 

Goals established in the Forest Plan for HEI would be met under this alternative. Open road 

density would increase temporarily above standards during implementation, but would then be 

reduced to below the maximum included in the plan standards for General Forest. Current ratios 

in cover and forage availability would be altered, resulting in a shift from 52 to 23 percent cover 

on General Forest Winter Range; from 52 to 20 percent cover on Winter Range and 36 to 29 

percent cover on General Forest. A ratio of 40 percent land in cover to 60 percent land in forage 

is thought to provide optimal deer and elk habitat (Thomas 1979). Satisfactory cover would be 

reduced by 895 acres on General Forest, 162 acres on General Forest Winter Range and 337 

acres on Winter Range, but road density would be reduced when closures are implemented on all 

three of these areas. Elk would continue to use the area, but cover would be limited in the shortterm. Cover availability is expected to increase as forest canopy recovers and road closures are 

expected to partially compensate for loss of cover. 

Tables 81, 82, and 83 display changes in HEI values. Initial decreases are due to reductions in 

cover and increases in road density. Final HEI values reflect partial compensation that results 

from road closures. 

Alternative 3 

Within General Forest, this alternative would reduce satisfactory cover by 801 acres and increase 

marginal cover by 801 acres. Total cover acres in General Forest would not change and there 

would be no change in percent cover and the cover quality index. Within General Forest Winter 

Range, this alternative would reduce satisfactory cover by 141 acres, and would reduce marginal 

cover by 617 acres. Total cover acres in General Forest Winter Range would be reduced by 758 

acres, resulting in a 24 percent reduction in percent cover and no change to the cover quality 

index. Within Winter Range, this alternative would reduce satisfactory cover by 338 acres and 

marginal cover by 1,217 acres. Total cover acres in Winter Range would be reduced by 1,555 

acres, resulting in 32 percent cover and no change to the cover quality index. 

Seasonal restriction on thinning, fuels, and related activities would be implemented between 

December 1 and May 1 in General Forest Winter Range and in Winter Range allocations. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 237 

This alternative would not reduce road densities. HEI would remain at 39.2 in General Forest, 

and would be reduced from 45.1 to 37.6 in General Forest Winter Range, and be reduced from 

53.8 to 14 in Winter Range. 

Goals established in the Forest Plan for HEI would be met under this alternative. Open road 

density would remain slightly above standards for General Forest. Current ratios in cover and 

forage availability would shift from 52 to 28 percent cover on General Forest Winter Range and 

from 52 to 20 percent cover on Winter Range. Cover would stay at 36 percent on General 

Forest. A ratio of 40 percent land in cover to 60 percent land in forage is thought to provide 

optimal deer and elk habitat (Thomas 1979). Satisfactory cover would be reduced by 801 acres 

on General Forest, 141 acres on General Forest Winter Range, and 338 acres on Winter Range. 

Road density would not be changed by this alternative. Elk would continue to use the area, but 

cover would be limited in the short-term. Cover availability is expected to increase as forest 

canopy recovers, which should occur relatively quickly under this alternative. Tables 81, 82, and 

83 display changes in HEI values. Decreases are due to reductions in cover. 

Alternative 4 

Within General Forest, this alternative would reduce satisfactory cover by 870 acres and 

decrease marginal cover by 513 acres. Total cover acres in General Forest would be reduced by 

1,383 acres, resulting in a 6 percent reduction of percent cover and no change to the cover 

quality index. Within General Forest Winter Range, this alternative would reduce satisfactory 

cover by 152 acres, and would reduce marginal cover by 688 acres. Total cover acres in General 

Forest Winter Range would be reduced by 840 acres, resulting in a 26 percent reduction in 

percent cover and no change to the cover quality index. Within Winter Range, this alternative 

would reduce satisfactory cover by 332 acres and marginal cover by 1,201 acres. Total cover 

acres in WR would be reduced by 1,533 acres, resulting in a 32 percent decrease of percent cover 

and no change to the cover quality index. 

Seasonal restriction on harvest, thinning, fuels and related activities would be implemented 

between December 1 and May 1 in General Forest Winter Range and in Winter Range 

allocations. 

Alternative 4 would initially increase road density in the short term (during implementation) as 

follows: Winter Range 0.1 miles per square mile. After timber and follow-up operations are 

complete, road closures would reduce road density by 0.3 miles per square mile in General 

Forest, 0.2 miles per square mile in General Forest Winter Range, and 0.5 miles per square mile 

in Winter Range. Combined with the cover effects described above, HEI would be decreased 

from 39.2 to 33.6 in General Forest, decreased from 45.1 to 40.0 in General Forest Winter 

Range, and reduced from 53.8 to 15.5 in Winter Range. 

Goals established in the Forest Plan for HEI would be met. Open road density would remain 

slightly above standards during implementation, but would then be reduced to below the 

maximum included in the Forest Plan for General Forest. Current ratios in cover and forage 

availability would be altered, resulting in a shift from 52 to 26 percent cover on General Forest 

Winter Range; from 52 to 20 percent cover on Winter Range and 36 to 30 percent cover on 
Chapter 3 - Affected Environment and Environmental Consequences

General Forest. A ratio of 40 percent land in cover to 60 percent land in forage is thought to 

provide optimal deer and elk habitat (Thomas 1979). Satisfactory cover would be reduced by 

870 acres on General Forest,152 acres on General Forest Winter Range and 332 acres on Winter 

Range, but road density would be reduced when closures are implemented in all three of these 

areas. Elk would continue to use the area, but cover would be limited in the short term. Cover 

availability is expected to increase as forest canopy recovers and road closures are expected to 

partially compensate for loss of cover. Tables 81, 82, and 83 display changes in HEI values. 

Initial decreases are due to reductions in cover and increases in road density. Final HEI values 

reflect partial compensation that results from implementation of road closures. 

Alternative 5 

Within General Forest, this alternative would reduce satisfactory cover by 788 acres and 

decrease marginal cover by 246 acres. Total cover acres in General Forest would be reduced by 

1,034 acres, resulting in a 4 percent reduction of percent cover and no change to the cover 

quality index. Within General Forest Winter Range, this alternative would reduce satisfactory 

cover by 155 acres, and would reduce marginal cover by 680 acres. Total cover acres in General 

Forest Winter Range would be reduced by 835 acres, resulting in a 26 percent reduction in 

percent cover and no change to the cover quality index. Within Winter Range, this alternative 

would reduce satisfactory cover by 334 acres and marginal cover by 1,209 acres. Total cover 

acres in Winter Range would be reduced by 1,543 acres, resulting in a 32 percent decrease of 

percent cover and no change to the cover quality index. 

Seasonal restriction on harvest, thinning, fuels and related activities would be implemented 

between December 1 and May 1 in General Forest Winter Range and in Winter Range 

allocations. 

Alternative 5 would initially increase road density in the short term (during implementation) as 

follows: Winter Range 0.1 miles per square mile. After timber and follow-up operations are 

complete, road closures would reduce road density by 0.3 miles per square mile in General 

Forest; 0.2 miles per square mile in General Forest Winter Range; and 0.2 miles per square mile 

in Winter Range (compared to existing conditions). Combined with the cover effects described 

above, HEI would be decreased from 39.2 to 38.5 in General Forest, decreased from 45.1 to 40.0 

in General Forest Winter Range, and reduced from 53.8 to 14.5 in Winter Range. 

Goals established in the Forest Plan for HEI would be met under this alternative. Open road 

density would not change, but would remain slightly above standards during implementation, but 

would then be reduced to below the maximum included in the plan standards for General Forest. 

Current ratios in cover and forage availability would be altered, resulting in a shift from 52 to 26 

percent cover on General Forest Winter Range; from 52 to 20 percent cover on WR and 36 to 32 

percent cover on General Forest. A ratio of 40 percent of land in cover to 60 percent land in 

forage is thought to provide optimal deer and elk habitat (Thomas, 1979). Satisfactory cover 

would be reduced by 788 acres on General Forest, 155 acres on General Forest Winter Range 

and 334 acres on Winter Range, but road density would be reduced when closures are 

implemented on all three of these areas. Elk would continue to use the area, but cover would be 

limited in the short-term. Cover availability is expected to increase as forest canopy recovers,

which should occur quickly under this alternative within treatment units where higher stocking 

levels are to be retained by prescription within PFA, pileated feeding habitat, connective 

corridors, satisfactory cover and mesic swales and drainages. Road closures are expected to 

partially compensate for loss of cover. Tables 81, 82, and 83 display changes in HEI values. 

Initial decreases are due to reductions in cover and increases in road density. Final HEI values 

reflect partial compensation that results from implementation of road closures.

The analysis indicates that the project area meets HEI standards for General Forest, General 

Forest Winter Range, and Winter Range. 

Cumulative Effects 

There were approximately 260 acres of satisfactory and marginal cover reduced by the Hash 

Rock Fire, but the habitat effectiveness values for cover quality and quantity did not change, due 

to the relatively small number of acres in relation to the total number of acres in the project area. 

Therefore, the Habitat Effectiveness Index (HEI) values did not change for the project area as a 

result of the Hash Rock Fire. 

Within the project area 13.5 miles of open road exist in Winter Range (MA-20), resulting in an 

open road density of 1.8 miles/square mile. There are also 12.2 miles of open road in General 

Forest Winter Range (MA-21), resulting in an open road density of 2.5 miles per square mile. 

Ongoing activities are planned that would reduce accessibility of roads in Winter Range (MAF20) between December 1 and May 1 of each year by reinforcement of existing closures. 

Seasonal restrictions would be required for road work within these allocations between 

December 1 and May 1 of each year. All alternatives have seasonal road closures in place to 

meet Forest Plan road density requirements. Monitoring would be conducted to confirm that the 

existing closure program is being effectively implemented to the extent necessary to meet this 

requirement. If this standard is not being met, then modifications will be made to the existing 

closure program to ensure that the seasonal standard is met. 

In the Marks Creek Watershed and Veazie Creek drainage approximately 5,098 acres were 

treated with commercial timber harvest within General Forest in the last 30 years. The majority 

of these treatments were regeneration harvests. These treatments reduced the abundance of both 

satisfactory and marginal cover for elk. At the same time fire exclusion has allowed the 

development of moderate to dense canopy closure (cover) in other areas. The proposed 

alternatives further reduce the percent cover in General Forest. Combined with the proposed 

action the net cumulative effect is that the percent cover will be as displayed in Table 81. 

Within General Forest Winter Range approximately 1,019 acres were treated with commercial 

timber harvest or post fire salvage in the Marks Creek Watershed during the last 35 years. The 

majority of these treatments were regeneration prescriptions. These treatments reduced the 

abundance of both satisfactory and marginal cover for elk. The proposed alternatives reduce the 

percent cover as described above. The net cumulative effect is that the percent cover be as 

displayed in Table 82. 

In Winter Range approximately 414 acres have been treated with commercial timber harvest in 

the Marks Creek Watershed and Veazie Creek drainage during the last 30 years. These 

treatments reduced cover for elk. The percent cover goal for Winter Range is relatively low 

based on site potential and estimated capability to produce cover. All action alternatives would 

further reduce cover within this allocation, the net cumulative effect is that the percent cover will 

be as displayed in Table 83.

Short-term Uses and Long-term Productivity 

NEPA requires consideration of “the relationship between short-term uses of man’s environment 

and the maintenance and enhancement of long-term productivity” (40 CFR 1502.16). As 

declared by the Congress, this includes using all practicable means and measures, including 

financial and technical assistance, in a manner calculated to foster and promote the general 

welfare, to create and maintain conditions under which man and nature can exist in productive 

harmony, and fulfill the social, economic, and other requirements of present and future 

generations of Americans (NEPA Section 101). 

The action alternatives propose short-term harvest of timber, while enhancing the long-term 

health of forested stands. Existing conditions are outside the historic range of variability and 

may not be sustainable over the long term. Proposed activities including prescribed fire move 

conditions toward a balance of sustainable vegetative conditions. Soil and water are two key 

factors in ecosystem productivity and protection of these resources is provided by the design 

elements discussed in Chapter 2. Sustainable levels of timber, wildlife habitat, water quality, and 

other resources depend on maintaining the long-term soil productivity upon which vegetation 

relies. Quality and quantity of water from the project area would fluctuate as described 

previously, but no long-term effects to water resources are anticipated as a result of commercial 

harvest, precommercial thinning, and fuels reduction activities. All alternatives provide fish and 

wildlife habitat at levels necessary to maintain viable populations of the species within the 

project area. The amounts of suitable habitat vary with the level of activities in each alternative. 

Unavoidable Adverse Effects 

All of the action alternatives considered result in some adverse effects. Many of these adverse 

effects can be reduced through implementation of the design elements identified in Chapter 2. 

Even after minimizing these adverse effects, there are still some adverse effects that cannot be 

avoid. Adverse effects that cannot be avoided relate to air quality, noxious weeds, and soils. 

Air quality. All four action alternatives include underburning activities that would produce 

smoke, including particulate matter such as PM 10. Chapter 2 includes design elements, such as 

only burning when anticipated weather conditions would be favorable for smoke dispersion, to 

reduce the adverse effects from burning. However, weather cannot always be predicted and 

unexpected changes in weather conditions during burning may result in smoke pooling in 

inhabited areas. These effects cannot be avoided. Prescribed fire would not be ignited or would 

be suspended during persistent inversion conditions, which would decrease the potential for 

smoke pooling in the Marks Creek area. 

Non-native Invasive Species (noxious weeds). The potential for introduction and spread of 

noxious weeds exists under every alternative considered, including no action, and cannot be 

completely avoided. All of the action alternatives result in some areas that are conducive to the 

introduction and spread of noxious weeds. Design elements have been included in every action 

alternative to reduce these adverse effects. However, proposed activities such as commercial 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 242 

timber harvest, log haul, road construction and reconstruction, grapple piling, and underburning 

still result in conditions conducive to the introduction and spread of noxious weeds. 

Soils. Additional detrimental soil conditions are expected as a result of implementing 

Alternatives 2, 4, and 5. The use of tractor (ground-based) logging equipment would result in 

additional areas with detrimental soil compaction and displacement. Underburning and burning 

both grapple and landing piles would also result in small amounts of detrimental charring. The 

design elements in Chapter 2 and the unit-specific mitigation in Appendix B identify the resource 

protection measures that would minimize the unavoidable adverse effects to soils. Alternatives 

2, 4, and 5 were specifically designed to limit the amount of detrimental soil conditions 

consistent with Regional guidelines for soils. 

Road construction also results in adverse effects to soils that cannot be avoided. Road 

construction results in soil compaction and displacement. On roads that are decommissioned, the 

road surface can and would be revegetated, but soil productivity is still reduced because of 

compaction. These adverse effects to soils cannot be avoided. 

Irreversible and Irretrievable Commitments of Resources 

Irreversible commitments of resources are those that cannot be regained, such as the extinction 

of a species or the removal of mined ore. Irretrievable commitments are those that are lost for a 

period of time such as the temporary loss of timber productivity in forested areas that are kept 

clear for use as a power line right-of-way or road.

Irreversible commitments are decisions affecting nonrenewable resources such as soils, wetlands, 

roadless areas, and cultural resources. Such commitments are considered irreversible because 

the resource has deteriorated to the point that renewal can occur only over a long period of time 

or at great expense or because the resource has been destroyed or removed. 

The construction of roads, to provide access to timber, is an irreversible action because of the 

time it takes for a constructed road to revert to natural conditions. Alternatives 2, 4, and 5 

propose some level of road construction. 

Removing aggregate (gravel) from mineral material sources would result in an irreversible 

commitment of resources. Once aggregate is removed from material source sites and placed on 

roads, it cannot be renewed. 

Irretrievable commitments of natural resources involve the loss of production or use of resources 

for a period of time. This represents opportunities foregone for the period of time that the 

resource cannot be used. 

Timber stands that are not managed at this time present an irretrievable loss of growth potential. 

Although the lost growth is irretrievable, it is not irreversible because the stands may be 

managed at a later date.

Cumulative Effects 

Cumulative effects have been discussed throughout this chapter. As discussed in the June 24, 

2005, Council on Environmental Quality Memorandum on Guidance of the Consideration of 

Past Actions in Cumulative Effects Analysis, past actions that warrant consideration because 

they are continuing to cause identifiable effects in the project area have been considered. For 

example, in the last 30-35 years there has been regeneration harvest on more than 7,000 acres. 

Regeneration harvest reduced the amount of LOS and wildlife habitat in the project area. This 

past harvest was considered in the sections on LOS and wildlife species such as the goshawk and 

pileated woodpecker. Past activities that have changed the environmental baseline have been 

included in the description of the affected environment. For example, in the analysis of effects to 

soils, past harvest activities using ground-based equipment resulted in detrimental soil 

conditions. The unit-by-unit analysis for soils contained in Appendix B describes the existing 

amount of detrimental soil conditions by alternative. Much of the detrimental disturbance was 

caused by past harvest. Other events in the project area such as the Hash Rock Fire of 2000 and 

the Marks Creek Burn in 1968 are also discussed where appropriate. 

Other Required Disclosures 

NEPA at 40 CFR 1502.25(a) directs “to the fullest extent possible, agencies shall prepare draft 

environmental impact statements concurrently with and integrated with ... other environmental 

review laws and executive orders.” 

National Forest Management Act 

To ensure consistency with the National Forest Management Act, the Ochoco National Forest 

Land and Resource Management Plan, as amended, was consulted. The Forest Plan contains 

several standards and guidelines that apply forest-wide or to specific management areas. Both 

forest-wide and management area specific standards and guidelines were reviewed. Table 84 

briefly identifies the applicable standards and guidelines and how the alternatives are consistent. 

If the alternatives are not consistent, a brief description of the needed Forest Plan amendment is 

included. In addition, the requirements at USC (United States Code) 1604(g)(3) were reviewed 

and the proposed activities are consistent. 

Alternative 1 is the no action alternative and is not included in Table 84 because no management 

activities would occur. 

All of the action alternatives are consistent with long-term management objectives as discussed 

in the Forest Plan as amended. However, Alternatives 2 and 4 would require three amendments, 

Alternative 3 would require one amendment, and Alternative 5 would require two amendments. 

These amendments are briefly discussed in the alternative descriptions in Chapter 2 and in Table 

84. 

Amendment 1 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 244 

The Eastside Screens (aka Regional Forester’s Forest Plan Amendment No. 2) contain standards 

that indicate there should be no net loss of LOS if either one or both of the LOS stages are below 

HRV. The eastside screens also indicate that some timber sale activities can occur within LOS 

stages that are within HRV, such as manipulating one type of LOS to move stands into the LOS 

stage that is deficit if it meets historical conditions. Currently, the amount of multi-strata LOS in

the Douglas-fir PAG is within HRV and single-strata LOS is below HRV. Timber harvest in 

multi-strata LOS within the Douglas-fir PAG is designed to reduce competition and maintain 

large trees in this area; these stands would be converted to single-strata LOS. Following 

treatment, multi-strata LOS would be below HRV. A Forest Plan amendment is needed to allow 

this activity in Alternatives 2, 4, and 5 because the Eastside Screens does not allow timber sale 

activities to move multi-strata LOS below HRV. 

These commercial harvest activities are designed to reduce stand density, improve growth of the 

residual trees, and reduce potential mortality resulting from inter-tree competition. Commercial 

harvest would more quickly restore historic seral/structural stage conditions and improve 

growing conditions for larger trees than no action, noncommercial thinning alone, or prescribed 

fire alone. Commercial harvest would also decrease the probability of wildfires and decreases 

the severity of wildfire impacts. No trees greater than 21 inches dbh would be cut and removed 

in any area except in isolated cases for safety reasons or for road construction. 

This amendment is consistent with the Regional Forester’s June 11, 2003, letter on guidance for 

implementing Eastside Screens. In that letter the Regional Forester encouraged Forest 

Supervisor’s to encourage site-specific Forest Plan amendment that would meet LOS objectives 

of increasing the number of large trees and LOS on the landscape. The commercial harvest 

proposed in multi-strata LOS in the Douglas-fir PAG is consistent with the intent of the Eastside 

Screens to maintain and/or enhance LOS. 

Timing – The Forest Plan has been in effect since 1897. This amendment is occurring during the 

second decade of the plan period and is less likely to be significant. The commercial harvest 

treatments in Alternative 2, 4, and 5 are expected to be implemented within the next 5 years. 

Location and Size – In Alternative 2 approximately 309 acres would be treated out of the 988 

acres of multi-strata LOS in the Douglas-fir PAG within the 39,200 acre project area. In 

Alternative 4, approximately 216 acres would be treated. In Alternative 5, approximately 224 

acres would be treated. In all three alternatives, the acres that are treated would remain LOS; it 

would change from multi-strata LOS to single-strata LOS. 

Goals, Objectives, and Outputs – There would be no change in the long-term relationships 

between the levels of goods and services projected by the Forest Plan Final EIS and the impacts 

of implementing any of these alternatives because of the small number of acres treated and the 

objectives of the treatments (to maintain LOS in the long term). 

Management Prescription – The amendment applies only to this project area and would not apply 

to future decisions within the project area. The amendment does not alter the desired future 

condition of the land or resources or the anticipated goods and services to be produced. Only a 

small acreage would be treated and options for future management of LOS would be maintained. 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 245 

Amendment 2 

The Eastside Screens contain standards that indicate timber harvest should be deferred in 

connective corridors when all the criteria for connective corridors cannot be met. A Forest Plan 

amendment is needed to implement Alternatives 2 and 4 to allow commercial harvest within 

connective corridors. Commercial harvest in these alternatives would reduce canopy closure to 

less than two-thirds of site potential. The Eastside Screens indicate that canopy closure should be 

maintained within the top one-third of site potential. Connective corridors within the project area 

represent the best connections given the existing conditions resulting from physical restrictions 

such as ridges, meadows, and previous harvest practices. Timber harvest in Alternatives 2 and 4 

within connective corridors are designed to maintain existing large trees and promote development 

of additional large trees. Alternative 2 includes 787 acres of commercial harvest in connective 

corridors. Alternative 4 includes 700 acres of commercial harvest in connective corridors. This 

activity will help develop LOS in corridors and would improve connectivity in the long term. 

This amendment is consistent with the Regional Forester’s June 11, 2003, letter on guidance for 

implementing Eastside Screens. In that letter the Regional Forester encouraged Forest 

Supervisor’s to encourage site-specific Forest Plan amendment that would meet LOS objectives 

of increasing the number of large trees and LOS on the landscape. The commercial harvest 

proposed in connective corridors is consistent with the intent of the Eastside Screens to maintain 

and/or enhance LOS. 

Timing – The Forest Plan has been in effect since 1989. This amendment is occurring during the 

second decade of the plan period and is less likely to be significant. The commercial harvest in 

Alternatives 2 and 4 are expected to be implemented within the next 5 years. 

Location and Size – The project area contains 3,260 acres of connective corridors. Alternative 2 

includes 787 acres of commercial harvest in connective corridors. Alternative 4 includes 700 

acres of commercial harvest in connective corridors. The commercial harvest retains options for 

future management of connective corridors. Treatments would maintain existing large trees and 

would promote the development of additional large trees. 

Goals, Objectives, and Outputs – There would be no change in the long-term relationships 

between the levels of goods and services projected by the Forest Plan Final EIS and the impacts 

of implementing Alternatives 2 or 4 because of the few acres being treated and the objectives of 

the treatments (to maintain LOS in the long term). 

Management Prescription – The amendment applies only to this project and would not apply to 

future decisions. The amendment does not alter the desired future condition of the land or 

resources or the anticipated goods and services to be produced. Only a small acreage would be 

treated and options for future management of connective corridors would be maintained. 

Amendment 3 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 246 

The Forest Plan (p. 4-251) states that vegetative management (except livestock use) will not be 

allowed within MA-F6 Old Growth, until further research is available on the needs of the 

dependent species. All four action alternatives include precommercial thinning, hand piling, and 

underburning in the Stewart Springs OGMA. These activities are proposed to improve the 

longevity of large ponderosa pine on south and west facing slopes. The activities are consistent 

with the emphasis for the OGMA which is to provide habitat for wildlife species dependent on 

old growth stands. A Forest Plan amendment is needed because the activities are not consistent 

with the standard and guideline that indicates vegetative management is not allowed. 

Timing – The Forest Plan has been in effect since 1989. This amendment is occurring during the 

second decade of the plan period and is less likely to be significant. The proposed activities are 

expected to be implemented within the next 5-7 years. 

Location and Size – The project area contains three OGMAs. The alternatives includes activities 

on 70 acres out of 821 within OGMAs. No activities are proposed in the other two OGMAs 

within the project area. The proposed activities would maintain existing large trees. 

Goals, Objectives, and Outputs – There would be no change in the long-term relationships 

between the levels of goods and services projected by the Forest Plan Final EIS and the impacts 

of implementing any of the action alternatives because of the low number of acres being treated 

and the objectives of maintaining large trees. 

Management Prescription – The amendment applies only to this project and would not apply to 

future decisions. The amendment does not alter the desired future condition of the land or 

resources or the anticipated goods and services to be produced. Only a small acreage would be 

treated and options for future management would be maintained.

Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 258 

Clean Air Act 

The selected alternative is designed to be consistent with the Clean Air Act. The Oregon DEQ is 

responsible for assuring compliance with the Clean Air Act. In 1994, the Forest Service, in 

cooperation with the DEQ, the Oregon Department of Forestry, and the BLM, signed a 

Memorandum of Understanding (MOU) to establish a framework for implementing an air quality 

program in Northeast Oregon. The MOU includes a prescribed fire emission limit of 15,000 tons 

of PM 10 per year for the national forests of the Blue Mountains (Malheur, Ochoco, Umatilla, 

and Wallowa-Whitman). (PM 10 are particulate matter that measure 10 microns in diameter or 

less, and are small enough to enter the human respiratory system.) All prescribed burning on 

these forests is coordinated with the DEQ through the State of Oregon smoke management 

program. All prescribed fire activities proposed in the action alternatives would be conducted in 

compliance with the State of Oregon Smoke Management System and would meet smoke 

management objectives for total emissions. 

Clean Water Act 

The Clean Water Act establishes a non-degradation policy for all federally proposed projects. 

The action alternative meets anti-degradation standards through planning, application, and 

monitoring of Best Management Practices (BMPs). The Environmental Protection Agency has 

certified the Oregon Forest Practices Act and regulations as BMPs. The State of Oregon has 

compared Forest Service practices with the State practices and concluded that Forest Service 

practices meet or exceed State requirements. Site-specific BMPs have been designed to protect 

beneficial uses. Chapter 2 lists the design elements and resource protection measures that are 

common to all action alternatives. A number of these measures are BMPs. 

The Draft EIS documents the analysis of effects to streams listed on the Oregon State 303(d) list 

of Water Quality Limited Water Bodies for summer water temperature. These streams are: 

Marks, Little Hay, and Hamilton Creeks. Implementation of any of the action alternatives would 

not result in any measurable increase in water temperatures in any fish-bearing or non-fish 

bearing perennial stream in the project area. Commercial timber harvest and precommercial 

thinning activities were designed so that they do not reduce shade. There is a potential to 

increase water temperature in intermittent non-fish bearing streams (Class IV) when they are 

flowing, but this would not result in a violation of state water quality standards because these 

streams go dry before peak water temperatures occur in the project area. 

All four of the action alternatives will comply with the Clean Water Act. 

Endangered Species Act 

Biological Evaluations (BEs) have been prepared to document possible effects of proposed 

activities on threatened and endangered species in the project area. There are no endangered 

species known or suspected to occur on the Ochoco National Forest. Threatened species that are 

known or suspected to occur on the Ochoco National Forest include bull trout, mid-Columbia 
Chapter 3 - Affected Environment and Environmental Consequences 

Spears Vegetation Management Project Draft EIS ♦ Page 259 

River steelhead, northern bald eagle, and Canada lynx. Potential effects to these species were 

analyzed and the analysis is summarized in the BEs (February 9, 2007, Wildlife BE and January 

2007 BE for Aquatic Species) and in Chapter 3 of this Draft EIS. The analysis documents that 

there would be no effect to bull trout or mid-Columbia River steelhead. The project may affect, 

but is not likely to adversely affect northern bald eagle and Canada lynx. Consultation with the 

U.S. Fish and Wildlife Service has been completed. Consultation with the National Marine 

Fisheries Service is not needed. 

National Historic Preservation Act 

A cultural resource inventory has been completed for the project area. The activities in the 

preferred alternative have been designed to have either No Effect or No Adverse Effect to 

cultural resource sites through both protection and avoidance. 

Environmental Justice and Civil Rights 

Civil Rights legislations, including the Civil Rights Act (CR) of 1964, Title VI, prohibit 

discrimination in Forest Service program delivery. The underlying principal behind the Civil 

Rights Act is that no activity shall negatively affect minorities, woman, or persons with 

disabilities by virtue of their race, color, sex, national origin, religion, age, disability, or material 

or familial status. Executive Order 12898 directs each Federal agency to make achieving 

Environmental Justice part of its mission by identifying and addressing, as appropriate, 

disproportionately high and adverse human health or environmental effects of its programs, 

policies, and activities on minority populations and low-income populations. 

There is no known potential for disparate or disproportionately high effects from any of the 

alternatives considered in this environmental impact statement to low-income or minority 

populations. None of the alternatives considered would discriminate or negatively impact any 

individual or subset of the population described above.

APPENDIX A 

Description of Proposed Treatments 

Commercial harvest (HIM or HTH): This prescription would be used in overstocked stands 

with a surplus of merchantable sized trees, trees between 9 and 20.9 inches dbh. Most stands 

contain an existing component of large trees (greater than 21 inches dbh). Current stand 

conditions often include multiple canopies and dense stocking and may include all seral stages. 

The stands would be thinned from below to recommended stocking levels in Alternatives 2 and 

4. In Alternative 5, certain stands located within wildlife emphasis areas would have a higher 

residual stocking level and/or retain a portion of the stand in an untreated condition 

(approximately 10 percent untreated in stringers or 1/2 to 1 acre patches). Merchantable trees 

would be sold and removed from the stand. 

Recommended stocking levels vary depending on site quality, tree size, and species. For 

example, the desired density range for an uneven-aged ponderosa pine stand on a grand firpinegrass site is 89 to 133 trees per acre when the average diameter is 10 inches dbh. The basal 

area would be between 49 and 73 square feet per acre. If the average diameter were larger, then 

fewer trees would be retained but the residual basal area would increase. Fewer trees would be 

retained on drier sites relative to moister sites. Recommended stocking levels are derived from 

“Suggested Stocking Levels for Forest Stands in Northeastern Oregon and Southeastern 

Washington: An Implementation Guide for the Umatilla National Forest” (Powell 1999). 

Logging System: This proposal includes Tractor (T), Skyline (S), and Helicopter (H) logging 

systems. Tractor systems include the use of ground-based equipment such as tractors, rubbertired skidders, and feller/bunchers to move the logs to a landing where they can be loaded onto a 

truck. Tractor systems are usually prescribed in areas with slopes that are less than 35 percent. 

On steeper slopes, such as those more than 35 percent, skyline or helicopter systems are 

prescribed. Skyline systems include the use of a cable system to suspend the logs into the air to 

move them to a landing. Helicopter systems use a helicopter to lift logs into the air to move 

them to a landing. Helicopter systems are also used in areas less than 35 percent slope where 

there are concerns about using tractor systems. 

Yard Tops Attached (YTA): This activity includes moving cut trees with the tops still attached 

to a landing. The tops are then cut off at the landing area before the logs are loaded onto a truck. 

This activity is prescribed in areas where leaving the tree tops in the unit is likely to result in fuel 

loadings that are considered too high for activity-fuels underburning. This activity is only 

prescribed in combination with commercial harvest. 

Precommercial thinning (PCT): This activity cut small nonmerchantable trees generally less 

than 9 inches dbh. Diseased or damaged trees and juniper trees up to 12 inches dbh could 

The number of small trees left varies by stand depending on the overall stocking objectives and 

the amount of existing overstory. Where the objective in the stand is to have single-storied LOS 
Appendices 

Spears Vegetation Management Project Draft EIS ♦ Page 278 

and many large diameter trees exist, then few small understory trees would be retained (40 or 

less per acre). Where few overstory trees exist, such as in young plantations, then the 

precommercial thinning may retain 135 or more small trees per acre. Species retained are 

usually ponderosa pine and western larch. Species infected with/or susceptible to insects and 

disease are normally removed. Precommercial thinning can occur in combination with 

commercial harvest. Trees cut during this activity are usually left on site. Slash may be reduced 

by fuels treatments, such as underburning. 

Hardwood thinning (HWD): This activity is prescribed to reduce conifer competition in 

hardwood stands by cutting down and/or girdling conifers (mostly ponderosa pine) that have 

encroached into these areas. Commercial harvest would not occur in these stands. In general, 

conifers up to 15 inches dbh would be cut. Most, if not all, conifers within 50 feet of any aspen 

(including sprouts) or cottonwood tree would be cut down and left in place, or girdled and left 

standing. Slash generated from these activities would be lopped or hand piled. The slash would 

not be burned. To prevent browsing, fencing and/or individual tree cages may be installed. Two 

types of fencing may be used. In some stands, livestock fencing would be installed; livestock 

fencing is four-strand barbed or smooth wire approximately 4 feet in height. In some stands, 

buck and pole fences may be installed to discourage livestock; buck and pole fences will be 

created from slash. In other stands, big game fencing would be installed; big game fencing is 

smooth wire or plastic netting approximately 7 feet in height. Individual tree cages are 

constructed of hard wire mesh 2 to 4 feet in diameter and 3 to 4 feet in height. Cages are placed 

to protect individual or clumps of sprouts. 

Grapple piling (GP): This activity involves the use of a machine such as an excavator with a 

grapple on an articulating arm. The machine operates on existing skid trails and reaches out to 

pick up and pile material. It is estimated that the machine would be able to reach 60 to 70 

percent of the anticipated slash, breaking up its continuity and lowering the overall amount. 

Grapple piles would be located on existing skid trails or landings, be approximately 5 to 10 feet 

high and 10 to 15 feet in diameter. These grapple piles would generally be burned within 2 to 3 

years of piling. Grapple piling will not occur within RHCAs. 

Hand piling (HP): This activity involves the hand piling of material 0-5 inches dbh and stacked 

in line with the slope. Hand piles would be less then 6 feet in diameter and no taller than 4 feet. 

In general, hand piling will be used along private land boundaries and in areas that have too 

much slash to be underburned safely and are too steep for grapple piling. Hand piles would 

generally be burned within 2 to 3 years of piling. 

Jackpot burning (JP): During a jackpot burn, concentrations of fuels are ignited. Jackpot 

burning would result in a mosaic of lightly and moderately burned areas. Jackpot burning is 

expected to kill some trees and create small openings (less than 1/10th of an acre), but is not 

expected to result in changes in species composition. The follow up underburn would remove 

additional surface and ladder fuels. 

Underburning (UB): Prescribed underburning is the application of fire in pre-determined 

patterns under specified conditions to produce a desired average flame length and rate of spread. 

The most common ignition techniques are the strip head fire and the backing fire. A strip head 
Appendices 

Spears Vegetation Management Project Draft EIS ♦ Page 279 

fire involves igniting strips of fire across a slope, or with the wind, until one strip reaches the 

area burned by the strip ahead of it. Fire intensity and rate of spread is controlled by adjusting 

the distance between the strips, and the number of strips ignited at one time. A backing fire 

involves igniting a strip of fire and allowing that strip to “back” into the wind or downhill. Fire 

intensity and rate of spread is controlled by adjusting how often and where fire is ignited to keep 

it moving (Kilgore and Curtis 1987). Usually, prescribed fire units that face south and west are 

in prescription to burn in the spring. Units that face north and east do not usually dry out enough 

to burn in the spring, and are generally burned in the fall. Units that sit at lower elevations are 

generally burned in the spring, while units at higher elevations are generally not in prescription 

to burn until the fall. 

Alternative Specific Activities by Unit 

The following tables identify the specific activities that are prescribed in each unit, by 

alternative. The activities are displayed in sequential order. For example, in Unit 100 

precommercial thinning would occur and then underburning would occur. In Unit 110, the unit 

would be underburned, then commercial harvest would occur followed by precommercial 

thinning and a second underburn.
