Abstract: The Hell Canyon Ranger District of the Black Hills National Forest has prepared a Final 

Environmental Impact Statement (FEIS) in compliance with the National Environmental Policy Act

(NEPA), the Healthy Forest Restoration Act (HFRA) and other relevant Federal and State laws and 

regulations. The Hell Canyon Ranger District proposes to implement multiple resource management 

actions within the Vestal project area on National Forest lands as guided by the Black Hills National 

Forest Land and Resource Management Plan as amended. The focus of the proposed action is to 

reduce mountain pine beetle risk and fire hazard on National Forest lands surrounding the City of 

Custer, SD. Two alternatives are considered in detail. Alternative 1 is the No Action Alternative. 

Alternative 2 is the proposed action and includes vegetation treatments designed primarily to reduce 

the potential for mountain pine beetle caused mortality within the Vestal project area. Proposed 

treatments are also designed to reduce fire hazard. This FEIS discloses the direct, indirect and 

cumulative effects resulting from these two alternatives. The preferred alternative is Alternative 2, 

with minor modification to proposed treatments on four units.

Vestal Final Environmental Impact Statement Summary

SUMMARY

The Hell Canyon Ranger District of the Black Hills National Forest proposes to 

implement multiple resource management actions within the Vestal project area as 

guided by the Black Hills National Forest Land and Resource Management Plan and 

Phase II Amendment (Forest Plan). Due to the existing epidemic of mountain pine 

beetles (MPB) in the project area (see Appendix H), the Vestal project was developed 

under the authorities of the Healthy Forest Restoration Act (HFRA). The proposed action 

includes commercial and non-commercial vegetation treatments and prescribed burning 

to reduce mountain pine beetle risk and fire hazard on National Forest lands surrounding 

the City of Custer, SD. Proposed resource management actions apply only to National 

Forest lands. 

The Vestal project area surrounds the city of Custer, South Dakota within Custer County 

(see Map 1 in Appendix A). The project area includes approximately 43,516 acres;

25,823 (60%) of which are National Forest System lands and 17,693 (40%) which are 

private lands (including City or County properties). Given the project location around the 

City of Custer, there are extensive private dwellings, businesses, and government offices 

in this project area. The Hell Canyon Ranger District office and shop, as well as the 

Black Hills National Forest Supervisor’s Office, are also located within the project area.

High use developed recreation sites occur on private, State and Federal lands within or 

adjacent to the project area. Sites within the project boundary include; approximately 

eight miles of the Mickelson trail, Bismarck Lake campground, Crazy Horse Mountain, 

and numerous private campgrounds. Other recreation areas adjacent to the project area 

include Custer State Park. 

All state and county roads which access the City of Custer are within the project area for 

at least a portion of their length. Therefore, all visitors to Custer will travel through the 

project area.

The focus of the proposed action is to treat vegetation on a broad landscape scale to 

reduce the threat to ecosystem components from the existing MPB epidemic. The 

proposed action would also reduce fire hazard and consequently, the potential for highintensity, large-scale wildfire. Implications of continued spread of this MPB epidemic 

include increased tree mortality across the landscape, on both National Forest and private 

lands. Consequently, the further accumulation of hazardous fuels would increase the 

potential for severe large-scale wildfires threatening forest resources and other values

within the area including major changes in scenery and alteration of wildlife habitat. 

Schmid et al. 2007, states “the most important aspect of managing mature ponderosa pine 

stands on the Black Hills National Forest is minimizing MPB-caused mortality.” 

This action is needed because the Vestal project area is within an expanding mountain 

pine beetle epidemic. The Black Hills National Forest, Forest Supervisor, Craig Bobzien, 

has determined that a MPB epidemic is occurring in the project area (Appendix H). Over 

the past 3-4 years there has been a rapidly growing amount of MPB caused mortality in 

the southern Black Hills around the City of Custer. All measures of MPB activity 

indicate a rapidly growing MPB epidemic with a substantial increase in tree mortality 

over the past 3 years. Approximately 61% of ponderosa pine stands on National Forest 

lands in the project area are at high risk for MPB caused mortality. 
Vestal Final Environmental Impact Statement Summary 

ii

At this time, there are larger pockets of MPB activity in the northern and western parts of 

the project area. The southern parts of the project are less impacted at this time, but 

beetle activity is occurring there at a rapidly growing rate on both National Forest and 

private lands. Approximately 17,693 acres (40%) of the project area is private land with 

over 7,000 of those acres being forested. Private landowners are experiencing MPB 

caused mortality on their property and many are taking actions such as thinning, 

sanitation, cut and chunk, and individual tree spraying. Many private landowners are 

worried about the potential spread of MPB from National Forest lands to their own. This 

project would reduce MPB risk on National forest lands and would reduce the potential 

for MPB spread onto private lands. 

The Hell Canyon Ranger District held a public meeting to discuss the Vestal project on 

Wednesday, May 11, 2011 at the Custer High School, Custer, SD. The proposed action 

was described in a scoping document (April 20, 2011) and mailed to approximately 149 

individuals, tribal representatives, groups, government entities and other interested 

members of the public. The proposed action includes vegetation treatments, prescribed 

fire, and fuel treatments on National Forest lands only. 

The Forest Service evaluated the following alternatives:

Alternative 1 – No Action: The National Environmental Policy Act

(NEPA) requires the study of the ‘No Action’ alternative as a basis 

for comparing effects of the proposed action and other alternatives. 

The ‘No Action’ alternative assumes no implementation of any 

elements of the proposed action or other action alternatives would 

take place within the Vestal project area. This alternative represents 

no attempt to actively respond to the purpose and need for action or 

the issues identified during scoping. For example, there would be no 

effort to modify existing vegetation or related fuels conditions in the 

project area; current timber sales, fire suppression efforts, noxious 

weeds treatments and regular system road maintenance would 

continue on National Forest lands. 

Alternative 2 – Proposed Action: The proposed action is designed to 

address the purpose of and need for action. Strategies proposed to 

reduce mountain pine beetle caused mortality include, mechanical 

thinning to reduce density, and sanitation which removes green trees 

that have live beetle brood in them. This alternative would be most 

effective if implemented immediately. In the Black Hills, stands that 

are less than 80 ft2

/acre basal area are at a reduced risk. Therefore, 

reducing stand basal area is a preventative treatment. Sanitation is 

considered a suppression strategy because it directly removes beetle 

larvae from the forest, directly reducing beetle populations. A total of 

up to 25,449 acres, which includes pine encroachment, hardwood 

release, hardwood conversion, and sanitation, of the project area 

would receive vegetation treatments under this alternative. Fuel 

treatments, including thinning, deadfall (mechanical treatment of 

down logs and branches), and prescribed burning, would occur on up 

to 25,634 acres. The proposed action includes the following 
Vestal Final Environmental Impact Statement Summary 

 iii

modifications to the transportation system in the project area: 0.6 

miles of unauthorized road is needed for access and would be 

converted to a system road then closed following use; and 0.9 miles of 

system road would be closed to protect resources either with physical 

closures or gates. Refer to Appendix A for proposed action maps for 

both vegetation treatments and fuels treatments, as well as the 

transportation map noting proposed adjustments to the transportation 

system.

The deciding official will review the environmental analysis, all supporting documents 

and public input in order to make the following decisions: 

(1) Whether or not active management is appropriate in the Vestal project area at this 

time and if so, what actions should occur. 

(2) Whether the information in this analysis is sufficient to make a reasoned decision.

CHAPTER 1: INTRODUCTION

Document Structure

The Forest Service has prepared this Final Environmental Impact Statement (FEIS) in 

compliance with the National Environmental Policy Act (NEPA), the Healthy Forest 

restoration Act (HFRA) and other relevant Federal and State laws and regulations. This 

Draft Environmental Impact Statement discloses the direct, indirect, and cumulative 

environmental impacts that would result from the proposed action and no action 

alternatives. All numbers and figures are approximate measures based on known project 

conditions. The document is organized into five chapters: 

• Chapter 1: Introduction: The section 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 section provides a 

more detailed description of the agency’s proposed action. A summary comparison 

of the proposed action and no action alternatives is also provided in this chapter. 

• Chapter 3: Affected Environment and Environmental Consequences: This section 

describes the environmental effects of implementing the proposed action and no 

action alternatives. This analysis is organized by resource area (i.e. Silviculture, 

Wildlife, Recreation). The effects of the No Action alternative provide a baseline for 

evaluating and comparing to the proposed action alternative. 

• Chapter 4: Consultation and Coordination: This section provides a list of preparers, 

and also a list of agencies, groups and persons consulted during the development of 

the Vestal Final Environmental Impact Statement (FEIS).

• Chapter 5: Literature Cited and Glossary

• Index

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

analyses presented in the environmental assessment.

Additional documentation, including more detailed analyses of project-area resources, 

may be found in the project planning record located at the Hell Canyon Ranger District 

Office in Custer, South Dakota. 

Background 

The Vestal project area surrounds the city of Custer, South Dakota, encompassing a large 

amount (40%) of private land. The private, or non-Forest Service, lands are concentrated 

within the city limits, but occur as scattered parcels throughout the whole project area 

(see maps in Appendix A). There are extensive private dwellings, businesses, and 

government offices within the project area. These structures also occur throughout the 

project area (see Maps 6 and 7 in Appendix A). There are many high-use developed

recreational sites that occur on private, state, and federal lands within or adjacent to the 

project area. All visitors to the City of Custer will travel through the project area. 

The Black Hills National Forest, Forest Supervisor, Craig Bobzien, has determined that a 

MPB epidemic is occurring in the project area (Appendix H). Over the past 3-4 years 

there has been a rapidly growing amount of beetle caused mortality in the southern Black 

Hills around the City of Custer, on both National Forest and private lands. All measures 

of MPB activity indicate a rapidly growing MPB epidemic with a substantial increase in 

tree mortality over the past 3 years. Approximately 61% of ponderosa pine stands, on 

National Forest lands in the project area are at high risk for MPB caused mortality. 
Vestal Final Environmental Impact Statement Chapter 1

At this time, there are larger pockets of beetle activity in the northern and western parts 

of the project area. The southern parts of the project are less impacted at this time, but 

beetle activity is occurring there at a rapidly growing rate. The primary management tool 

for reducing MPB-caused mortality is to remove the infested trees and to reduce the 

overall density of the remaining trees through mechanical thinning. 

Private land is also being impacted by the MPB epidemic. Approximately 7,000 acres of 

private forested land occurs within the Vestal project area. Many land owners are taking 

steps to protect their properties by thinning stands, removing trees infested with beetles 

(sanitation), cutting and chunking of infested trees, and spraying individual trees to 

protect them against the MPB epidemic. Land owners have voiced their concern about 

adjacent National Forest lands infested with MPB and the continuing spread onto their 

own land. Mountain pine beetles are moving across all ownerships within this project 

area. 

Fire hazard is currently high to very high on approximately 84% of National Forest lands 

in the project area. This signifies substantial potential for large-scale, high-intensity 

wildfires to occur. Such fires could threaten lives and property, as well as, resource 

values. 

Custer County prepared a Community Wildfire Protection Plan (CWPP) which was 

approved by resolution in 2011 (resolution 2011-7). The CWPP identified the City of 

Custer at-risk community (ARC) as an urban interface environment with a high density of 

structures and infrastructure. In many areas the structures lack defensible fire protection 

space. There is a community watershed for municipal water source at high risk of fire 

impacts. Also there is a high potential for economic loss, and likelihood for loss of 

housing and businesses in the event of a wildfire. The Custer County CWPP identifies a 

3 mile radius from the city limits of the City of Custer as a Community at Risk boundary. 

This 3 mile ARC radius of the city limits is the Wildland Urban Interface (WUI). 

Healthy Forest Restoration Act (HFRA)

The Healthy Forest Restoration Act (HFRA) was signed by President Bush in 2003 (H.R. 

1904) for the purpose of expediting hazardous fuels reduction and forest restoration 

projects on Federal lands at risk of wildland fire or insect and disease epidemics. 

The HFRA is comprised of a variety of provisions to expedite hazardous fuels reductions 

on specific types of National Forest land. The Vestal Project is an authorized hazardous 

fuels reduction project under Section 102(a)(4). The project area meets the qualifications 

because of the existing MPB epidemic occurring within and adjacent to the project area, 

which poses a significant threat to resource values on National Forest and private lands 

(see Appendix H). The Vestal project will be analyzed under the provisions of the 

HFRA, Section 102(a)(4). 

The HFRA provided expedited procedures for complying with National Environmental 

Policy Act (NEPA) requirements. Section 104 of HFRA provides guidance on the range 

of alternatives studied and disclosed in the NEPA document. All authorized hazardous 

fuel reduction projects must be consistent with Forest Plan direction.

Location 

The Vestal project area is located surrounding the city of Custer, South Dakota within 

Custer County (see Map 1, Appendix A). The project area includes approximately 43,516 

acres; 25,823 (60%) of which are National Forest System lands and 17,693 (40%) which 

are private lands (including City or County properties). Given the project location around 

the City of Custer, there are extensive private dwellings, businesses, and government 

offices in this project area. The Hell Canyon Ranger District office and shop, as well as 

the Black Hills National Forest Supervisor’s Office, are also located within the project 

area. 

All state and county roads which access the City of Custer are within the project area for 

at least a portion of their length. Therefore, all visitors to Custer will travel through the 

project area.

The project area includes all or portions of lands with the following legal descriptions, 

Black Hills Meridian.

Management Direction

The Revised Land and Resource Management Plan (Forest Plan), as amended (2006), 

provides direction for the management of the forest. The Forest Plan contains 

management goals and objectives, management area direction, and identifies desired 

future conditions for the forest. Resource specialists reviewed the current condition of the 

project area and compared these conditions with the desired conditions identified in the 

Forest Plan including applicable goals and objectives. Opportunities for improvement 

were identified.

Management Areas

The Forest Plan assigns a management emphasis to each portion of the Forest to meet 

multiple-use objectives. For each designated management area (MA), Chapter 3 of the

Forest Plan includes a description of desired future conditions, goals, objectives, 

standards, and guidelines. Specific direction is provided for management of mountain 

pine beetle outbreaks and fuels. There are four management areas within the Vestal 

project area (Map 2, Appendix A). Table 2 displays the management area designations 

and acreage within the Vestal project area.

Forest Plan Goals and Objectives 

The Forest Plan establishes eleven multiple use goals and associated objectives for 

management of the Forest. The goals and objectives, applicable to specific resource 

management issues needing resolution, provide the basic direction for defining the 

purpose and need and subsequently developing the project proposal. The eleven Forest 

Plan goals are discussed in Chapter I of the Forest Plan. The Responsible Official for the 

Vestal Project has chosen to propose resource management actions that respond to Forest 

Plan Goals 2, 4, and 10. 

Goal 2: Provide for a variety of life through management of biologically diverse 

ecosystems.

Objective 201: Manage for a minimum of 92,000 acres of aspen, and 

16,000 acres of bur oak during the life of the Plan. The highest priority 

for hardwood restoration is where conifers (e.g., spruce and pine) have 

out-competed aspen adjacent to riparian systems that once supported 

beaver.

• Opportunity exists to increase/maintain hardwood communities by 

reducing pine competition within these stands. In addition, 

opportunities exist to enhance and expand hardwood inclusions by 

opening stand canopies and removing conifers. 
Vestal Final Environmental Impact Statement Chapter 1

6 

Objective 205: Manage for 122,000 acres of prairie grassland and 3,600 

acres of meadow during the life of the Plan. 

• Opportunity exists to maintain existing meadows within the project 

area. Most of these meadows are currently experiencing 

encroachment by pine. Meadows act as natural fuelbreaks. 

Goal 4: Provide for scenic quality, a range of recreational opportunities, and protection 

of heritage resources in response to the needs of the Black Hills National Forest visitors 

and local communities.

Objective 402: Provide natural appearing landscapes with diverse scenery 

and enhance opportunities to enjoy attractive settings... 

• Opportunity exists to enhance/maintain landscapes in and around 

existing recreation sites and throughout the project area, by 

removing MPB infested trees and thinning stands to reduce insect 

damage and wildfire hazard. In addition, removal of MPB infested 

trees would enhance public safety in these areas. 

Goal 10: Establish and maintain a mosaic of vegetation conditions to reduce occurrences 

of catastrophic fire, insect, and disease events, and facilitate insect and disease 

management and firefighting capability. 

Objective 10-01: Manage for 50 to 75 percent moderate-to-low fire 

hazard in the wildland-urban interface and reduce fire hazard within 

proximity of structures to current NFPA standards... 

• Opportunity exists to reduce existing fire hazard within WUI that 

currently exceeds objectives on National Forest System lands 

within the project area. 

Objective 10-04: Reduce or otherwise treat fuels commensurate with risks 

(fire occurrence), hazard (fuel flammability), and land and resource values 

common to the area, using the criteria in Forest-wide Guideline 4110. 

• Opportunity exists to treat fuels and reduce hazards within the 

project area. 

Objective 10-05: Manage wildfires using the appropriate response based 

on management area emphasis, existing values, risk of ignition, and fuel 

hazards within a given area. 

• Opportunity exists to reduce existing and activity fuels to a 

manageable level, facilitating a proactive and effective response to 

wildfire. 

Objective 10-06: Develop fuel management and protection strategies for 

intermixed land ownerships in partnership with private, state, and other 

federal agencies. 

• Opportunity exists to coordinate with the State and County based 

on goals established in the Custer County Community Wildfire 

Protection Plan (CWPP) to reduce fuels on both public and private 
Vestal Final Environmental Impact Statement Chapter 1

7 

lands in order to reduce the potential for large wildfires that could 

affect homes, infrastructure, and other ecosystem values. 

Objective 10-07: Where outbreaks of mountain pine beetle could present 

risks to management objectives for ponderosa pine, reduce acreage of 

ponderosa pine stands that are in medium or high risk for infestation. 

• Opportunity exists to reduce the acreage of pine stands at high risk 

of MPB infestations by removing infested trees and reducing the 

overall stand density. 

Forest-wide standards and guidelines related to insects and disease: 

Guideline 4201a: Plan management activities with consideration for 

potential insect or disease outbreaks. Use integrated pest management 

strategies where insect or disease outbreaks may adversely affect 

management objectives. Utilize preventive vegetation management 

practices, including silvicultural treatments, to protect forest stands from 

insect and disease epidemics. 

Standard 4201b: During scheduled management activities, minimize 

susceptibility to mountain-pine-beetle epidemics by reducing average 

basal area to 70 or less in pine stands, except where denser stands are 

needed to meet other management objectives. 

Standard 4201c: Use the following insect-and-disease protection measures: 

Manage vegetation in and adjacent to high-use recreation areas to improve forest 

conditions, as needed to maintain or improve the desired recreation settings(s) or 

to conserve R2 sensitive or species of local concern and snails. In and adjacent to 

developed recreation sites actively treat insect and diseases to reduce pest 

populations. 

Standard 4201d: Consider spatial array of stand conditions when planning 

harvests to reduce their potential for mountain pine beetle epidemics. For 

example, silvicultural treatments may be appropriate within or adjacent to dense 

mature stands.

Guideline 4205: Consider applying preventive silvicultural treatments or other 

integrated pest management strategies to National Forest System land adjoining 

other land ownerships to reduce the likelihood of insect and disease epidemics 

and spread. Plan suppression strategies to reduce mountain pine beetle 

populations in pine stands during epidemics. Prioritize according to values, risk 

and management objectives. Priority should be given to areas in which values to 

be protected exceed the cost of protection. 

Guideline 4206: Project plans should consider existing infestations of insects or 

disease within a project area. Activities should be designed to minimize the risks 

of spreading the infestation while still providing habitat for those wildlife species 

dependent upon the presence of insects and disease. 
Vestal Final Environmental Impact Statement Chapter 1

Management Area-specific Goals and Objectives

In addition to the Forest‐wide goals and objectives outlined in Chapter 1 of the Forest 

Plan, each management area (MA) has goals and objectives specific to that area (see 

Chapter 3 of the Forest Plan). In the event that a Forest‐wide goal or objective conflicts 

with a MA‐specific goal or objective, the more restrictive goal or objective will take 

precedent. Below is a summary of the needs and opportunities associated with the MAspecific goals and objectives in the Vestal project area.

Other Direction

The Healthy Forests Restoration Act (HFRA) of 2003 (H.R. 1904) provides improved 

statutory processes for hazardous fuel (including insect/disease) reduction projects and 

healthy forest restoration on National Forest System lands. Other supporting policy 

includes the Healthy Forest Initiative, intended to reduce administrative process delays 

related to implementation of fuels (and insect/disease) reduction projects; National Fire 

Plan, and The Federal Wildland Fire Management Policy. The main focus of this 

National guidance is an emphasis on reducing the probability and occurrence of largescale wildfire in fire adapted ecosystems, especially near at-risk communities and the 

wildland-urban interface (WUI); and to reduce the levels of insect infestations and 

disease which threaten forest resources on public and private lands. 

The HFRA contains a variety of provisions to expedite hazardous fuel reductions on 

specific types of National Forest land. The Vestal Project is an authorized hazardous fuel 

reduction project under Section 102(a)(4) of the Healthy Forests Restoration Act of 2003. 

The area qualifies under section 102(a)(4) because there is an existing mountain pine 

beetle epidemic occurring within and adjacent to the project area which poses a 

significant risk to resource values on National Forest and private lands (see 

Determination of Insect Epidemic letter, Appendix H).

Another provision of the HFRA regards the encouragement of communities to prepare a 

Community Wildfire Protection Plan (CWPP). Custer County has completed a CWPP

which was adopted by resolution in 2011. The plan discusses a 3 mile zone around 

Custer. This 3-mile zone is the WUI. The ‘at-risk’-community of Custer lies within the 

project area. Figure 1 displays the 3 mile WUI surrounding the ARC of Custer, as well 

as Keystone, Hill City and Pringle outside of the project area. In total, there are 17,693 

acres (40%) of private lands and approximately 3,200 structures including homes and 

businesses contained within this project area.

The following demonstrates the Vestal project’s consistency with applicable portions of 

the HFRA: 

• The proposed action is consistent with the Forest Plan 

• The proposed action does not include treatments within designated 

wilderness, wilderness study areas or other Federal land where timber 

harvest is prohibited. 
Vestal Final Environmental Impact Statement Chapter 1

12

• Collaboration with local governments, tribes and fire departments was 

conducted. 

• The proposed action is on land determined to contain a MPB epidemic 

with imminent risk to ecosystem components.

• The primary objective of the project’s purpose and need is to reduce MPB 

risk. 

Purpose and Need for Action

The primary purpose for action in the Vestal project area is to reduce the threat to forest 

resources from the existing MPB epidemic. This action is needed because there is a 

rapidly increasing MPB outbreak occurring within the project area, on National Forest 

and private lands, which is resulting in substantial levels of pine mortality. The MPB are 

infesting trees across all ownerships. Many landowners have experienced MPB caused 

mortality on their land and are taking action to reduce the potential for further mortality 

Existing stand conditions across the project area are largely at high risk for MPB caused 

mortality. 

A secondary purpose of this project is to protect local communities and watersheds from 

large-scale, high intensity wildfire. This action is needed because the project area is 

located within and surrounding the City of Custer, SD and approximately 84% of 

National Forest lands within the project area have a fire hazard rating of high to very 

high. This is due to dense stand conditions and dead, dry fuels resulting from MPB 

caused mortality. Approximately 40% of lands in the project area are privately owned, 

with an estimated 3,194 private structures. 

Proposed Action

The action proposed by the Forest Service is designed to address the purpose and need 

for action described above. All proposed activities would occur on National Forest lands. 

Refer to proposed action maps 6, 7, and 8 in Appendix A for both vegetation treatments 

and fuels treatments, as well as the transportation map noting proposed adjustments to the 

transportation system. The proposed action and no action alternatives are presented in 

more detail in Chapter 2. 

Strategies proposed to reduce mountain pine beetle caused mortality include, mechanical 

thinning to reduce stand density to reduce risk, and sanitation which removes green trees 

that have live beetle brood in them. It is recommended that treatments be implemented as 

soon as possible to be most effective. In the Black Hills, stands that are less than 80 

ft2

/acre basal area are at a reduced risk. Further lowering densities would further lower 

the MPB risk. Therefore, reducing stand basal area is a preventative treatment. 

Sanitation is considered a suppression strategy because it directly removes beetle larvae 

from the forest, directly reducing beetle populations. 

Proposed activities include vegetation treatments on approximately 25,449 acres. This 

acreage includes all potential treatments. Vegetation treatments would consist of 

commercial thinning, free selection, group shelterwood, hardwood conversion, hardwood 

release, overstory removal, pine encroachment, sanitation, shelterwood seedcut, variable 

density thinning, precommercial thinning, and products other than logs (POL) thinning. 
Vestal Final Environmental Impact Statement Chapter 1

13

Not including possible sanitation treatments, there are 19,779 acres of treatments 

proposed in pine stands. This is 84% of pine stands within the project area. Table 3 in 

Chapter 2 provides a more detailed description of treatments and acres. Other fuels 

treatments that focus on further reducing fire hazard within the project area include 

approximately 180 acres of fuelbreaks adjacent to some private property boundaries, 

1,761 acres of prescribed burning and up to 23,693 acres of deadfall treatment. All 

proposed treatments are described in detail in Chapter 2. 

There are approximately 125 miles of Forest Service system roads in the project area. Of 

these roads, 48 miles are closed yearlong, 35 miles are open seasonally (May 15 to 

December 15), and 42 miles are open yearlong. In addition to Forest Service system 

roads, there are approximately 28 miles of County roads. The 2010 Forest Travel 

Management decision and associated Motorized Vehicle Use Map (MVUM) 

administratively closed all unauthorized roads in the project area (approximately 39 

miles) and prohibited all off-road motorized travel. 

The proposed action includes the following modifications to the transportation system in 

the project area: 0.6 miles of unauthorized road is needed for access and would be 

converted to system road then closed following use; 0.1 mile of new road construction to 

avoid private land-this is behind a yearlong closure gate and would not be open; and 0.9 

miles of system road would be closed to protect resources either with physical closures or 

gates (see Map 8, Appendix A).

Decision Framework

The deciding official will review the environmental analysis, all supporting documents 

and public input, in order to make the following decisions: 

• Whether or not active management is appropriate in the Vestal project area at this 

time and if so, what actions should occur, and 

• Whether the information in this analysis is sufficient to make a reasoned decision. 

If the proposed action is selected, project activities could begin as early as spring 2012. 

Public Involvement

The following public involvement and collaboration efforts have occurred: 

• A Notice of Intent (NOI) to prepare an EIS was published in the Federal Register

on April 22, 2011. The NOI requested public comment on the proposal and 

included the date and place of the scheduled public meeting. 

• A detailed scoping document was mailed to approximately 150 individuals, tribal 

representatives, groups, government agencies and other interested members of the 

public. This document also noted the time and place of the public meeting. 

• All scoping documents were posted to the Black Hills National Forest website and 

Schedule of Proposed Actions. 

• The proposal was discussed at the Custer Rotary Club meeting on April 25, 2011. 

• The proposal had been discussed at several of the Custer County Commissioners 

meetings, as well as at the City of Custer meetings. 
Vestal Final Environmental Impact Statement Chapter 1

14

• The proposal was presented as a topic at the Custer Volunteer Fire Department 

meeting on 5-3-11. 

• A News Release was sent to media outlets on April 28, 2011, announcing the 

Vestal project, requesting comments on the proposal and noting the time and 

place for the public meeting. Articles appeared in both the Custer Chronicle and 

the Rapid City Journal. 

• A public meeting was held at the Custer High School on May 11, 2011. Two 

South Dakota State employees participated in this meeting to provide information 

to private landowners on how to protect their property from MPB and wildfire. 

• The project was presented at the Tribal consultation meeting on June 22, 2011. 

In addition to the specific meetings listed above, the Forest Service has actively worked 

with the City, County, State and others in an informal manner to address MPB risk and 

fuel hazard. 

Using the comments from the public, other government agencies, groups, and tribal 

representatives the interdisciplinary team (IDT) identified issues that warranted further 

design criteria and determined whether additional alternatives or measures were needed. 

Issues

Comments received during the scoping process are used to help define issues, determine 

whether additional action alternatives or mitigation measures are necessary, and frame 

the analysis of environmental issues. A total of 27 parties provided feedback via letters,

fax, public meeting transcripts, hand delivery, or email during the formal scoping 

process. Comments received and the agency ‘response to comments’ are summarized in 

the Vestal project record located at the Hell Canyon Ranger District office, Custer, SD. 

The majority of the concerns raised during the scoping period were relatively minor 

issues that would be addressed through the application of Forest Plan standards and 

guidelines or other design criteria. None of the issues raised merited the development of 

additional action alternatives. 

A description of the two key issues, with measurement indicators, follows below: 

1. Mountain Pine Beetle Epidemic

Some commentors are concerned that the risk of MPB caused mortality will 

continue to be too high in the project area after proposed treatments are 

completed, either because some sites would be deferred or because the proposed 

treatments are not aggressive enough. Other commentors question whether an 

epidemic is occurring throughout the project area and suggest that proposed 

treatments are too aggressive and unnecessary. 

Measurement indicators: 

• Acres of Low MPB Risk 

• Acres of High MPB Risk

2. Wildfires and Fire Hazard

There is internal and external concern that the current MPB epidemic is creating 

and increasing fuel loadings in the project area. Fire hazard is high or very high 
Vestal Final Environmental Impact Statement Chapter 1

15

over a substantially large portion of the project area (84%). The City of Custer is 

entirely within the project area boundary and would be threatened if a wildfire 

were to occur under such fire hazard conditions. 

Measurement indicators: 

• Acres of Fire Hazard Rating 

• Mechanical Treatments

• Fuel break Construction 

• Natural fuel break maintenance or enhancement (aspen and meadow)

• Acres of Prescribed burning 

These issues lead the IDT to clarify components of the proposed action that were not 

made explicit during the scoping phase of the project. No issues raised merited the 

development of additional action alternatives. Documentation of each comment received, 

the issues identified in the comments and the rationale for identifying them as nonsignificant are located in the Vestal project record.

CHAPTER 2: COMPARISON OF ALTERNATIVES, 

INCLUDING THE PROPOSED ACTION

This chapter describes and compares the alternatives considered in detail for the Vestal

project, including the No Action alternative (Alternative 1) and the Proposed Action 

(Alternative 2). It also briefly describes alternatives not considered in detail and provides 

rationale for why they are not considered in detail. The alternatives are also presented in 

comparative form, defining the differences between each alternative and providing a clear 

basis for choice among options by the decision maker and the public. 

Alternatives Considered in Detail

The Forest Service developed two alternatives: a no action and a proposed action 

alternative. The alternatives considered in detail by the IDT are discussed below. This 

section provides the summary of activities proposed to occur during implementation of 

the action alternative. Exact figures, such as acres, miles, or other numerical units of any 

particular activity, may vary slightly. These figures, which are based on inventory and 

survey estimates, may vary during preparation of a timber sale, prescribed burn, or other 

project based upon various site factors such as topography, non-uniform site structure, 

fuels, refinement of the standard of road needed, etc. 

The Vestal project is an authorized hazardous fuels project pursuant to Section 102 (a)(4) 

of the HFRA. Section 104 of the HFRA provides guidance on the range of alternatives 

studied in detail and disclosed in the NEPA document. 

Alternative 1 – No Action

National Environmental Policy Act (NEPA) requires the study of the ‘No Action’ 

alternative as a basis for comparing effects of the proposed action and other alternatives. 

Under the No Action alternative, current management plans would continue to guide 

management of the project area. This alternative represents no attempt to actively 

respond to the purpose and need for action or the issues presented during scoping. No 

effort would be made to modify existing vegetation or related fuel conditions within the 

project area. No vegetation treatments, fuels treatments, or prescribed burning would be 

implemented.

Alternative 2 – Proposed Action

This alternative was developed to meet the purpose and need for action. It would also 

move conditions within the project area toward desired future conditions as described in 

the Forest Plan. The proposed action would treat vegetation within the project area on a 

broad landscape scale to reduce the threat to ecosystem components, including forest 

resources, from the existing insect and disease (mountain pine beetle) epidemic and 

reduce the potential for large-scale, high intensity wildfire.

Strategies proposed to reduce mountain pine beetle (MPB) caused mortality include, 

mechanical thinning to reduce basal area, and sanitation which removes green trees that 

have live beetle brood in them. Reducing stand basal area is a preventative treatment and 
Vestal Final Environmental Impact Statement Chapter 2

17

Commercial Thinning (60 BA)

Commercial Thinning (60 BA)

Commercial Thinning (50 BA)

would be most effective if implemented as soon as possible. Sanitation is considered a 

suppression strategy because it directly removes MPB larvae from the forest, reducing 

MPB populations. The use of silvicultural means to control stand conditions is effective 

as a long-term strategy to minimize MPB caused mortality and risk. The actions 

proposed in this alternative are as recommended by project Entomologist. According to 

Schmid et al. 2007, the most important aspect of managing mature ponderosa pine stands 

in the Black Hills National Forest is minimizing MPB-caused mortality. 

Proposed vegetation treatments for Alternative 2 include both commercial and 

noncommercial treatments. All treatments would occur on National Forest lands only 

and all forested acres would include sanitation treatment. Treatments are summarized 

below and displayed on Maps 6 and 7 in Appendix A. 

Commercial Thinning (CT)

3,626 acres 

CT50

1,831 acres

Thinning of trees generally 5-15” dbh. 

The objective is to reduce susceptibility 

to mountain pine beetle (MPB) 

infestation by reducing basal area within 

sites. 

The thinning would reduce MPB risk in these stands to Low and would also reduce fire 

hazard, improve health, tree vigor, and future growth capacity of the site. 

Sites would be thinned from below, which means that trees would, in general, be 

removed from the lower crown classes.

Typical target basal area (BA) is 60 ft2/ac. Some sites would be thinned to a BA of 50 

ft2/ac to further reduce fire hazard adjacent to private lands, and are noted as CT50. 

Post-treatment stands would be in a structural stage 4A condition. 
Vestal Final Environmental Impact Statement Chapter 2

18

Overstory Removal-would remove mature trees from 

stands which are regenerated

Would reduce MPB risk in these 

stands to Low and would also reduce 

fire hazard by reducing stand density 

to a basal area of 30-50 ft2/ac. 

This is an even-aged regeneration 

harvest used in mature sites, in 

which the most desirable seed trees 

are retained. 

Overstory Removal (OR)

1,255 acres

Removal of mature to overmature trees in the overstory of 

sites which have successfully 

regenerated. This treatment 

releases the established 

regeneration, which would also 

be thinned to a POL or PCT, 

unless deferred for wildlife 

cover. This would also result 

in Low MPB risk of stands and 

reduces fire hazard. 

Shelterwood Seedcut

Shelterwood Seedcut (SWSC)

226 acres 

Free Selection (FS)

1,054 acres 

Would reduce susceptibility of stands to MPB infestation by 

reducing overall basal area within sites. The thinning would not 

result in a low MPB risk in these stands, but the reduction in density 

is a benefit to MPB susceptibility and would also reduce fire hazard. 

This treatment reduces overall density of the site to an average 80 

ft2/ac basal area by interspersing dense groups with interlocking 

crowns of 3 trees up to 2 acres with openings, hardwoods and 

thinned areas. Within stand densities will vary from 0 to 120 ft2

/ac 

basal area.
Vestal Final Environmental Impact Statement Chapter 2

19

Aspen/Conifer Stand

Group Shelterwood (GSH)

10,044 acres

Would reduce susceptibility of stands to MPB infestation by reducing overall basal 

area within sites. Would reduce overall MPB risk in these stands to Low and also 

reduces fire hazard and maintain stand diversity. 

This treatment represents the shelterwood silviculture system and is proposed within 

pine sites which are not homogenous, but rather have two or more patches or groups 

of trees of various age classes throughout the stand. The shelterwood system is a 

common silvicultural treatment system which begins with a commercial thinning of 

smaller diameter trees to increase the size and vigor of residual trees, followed by a 

seedcut which is done to encourage regeneration; then completed with an overstory 

removal which releases the established regeneration. 

This prescription is proposed in sites with stand conditions which represent at least 

two phases of a shelterwood system such as a commercial thin, seedcut or overstory. 

The overall density of these stands would not exceed 60 ft2/ac basal area.

Variable Density Thinning (VDT)

1,072 acres 

Would reduce overall MPB risk in stands to Low and would also reduce fire hazard, 

by reducing overall stand density to a basal area of 60-80 ft2/ac. This thinning 

maintains or creates diversity within the stand by varying residual density from 30-90 

ft2/ac to avoid even residual tree spacing. Sites would be thinned from below, which 

means that trees would, in general, be removed from the lower crown classes.

Hardwood Release (HR)

431 acres

The objective is to maintain 

natural fuelbreaks by removing 

all conifers from existing 

hardwood habitat. Hinging of 

non-commercial-sized conifers 

would follow commercial 

removal.
Vestal Final Environmental Impact Statement Chapter 2

20

Aspen/Conifer Stand

POL Thinning

Hardwood Conversion (HC)

126 acres

The objective is to increase natural 

fuelbreaks by converting mixed 

conifer/hardwood stands to 

hardwood cover type. It would be 

accomplished by removing all 

conifers from the stand. Hinging 

of non-commercial-sized conifers 

would follow commercial 

removal.

Products Other than Logs 

(POL) 

617* acres

* Acres shown are those where PCT or 

POL are proposed as individual 

treatments. Both PCT and POL would 

also occur following other treatments as 

noted. 

A thinning of pine sites to reduce MPB risk and fire hazard by reducing stand density. This 

treatment is proposed in sites generally made up of trees 1-9” dbh that do not contain enough 

9” + trees to make sawtimber removal economically viable, or as a follow-up treatment to 

commercial thinning, variable density thinning, free selection, or the commercial thinning 

component group shelterwood, when the target basal area cannot be obtained by removal of 

sawtimber only. 

Overall stand density will not exceed 60 ft2/ac except in the VDT and FS sites where density 

will not exceed 80 ft2/ac basal area. 

The target residual tree spacing varies as follows: 

POL only – 18 x 18 feet

CT60 – 20 x 20 feet

CT50 – 22 x 22 feet

VDT and FS - variable spacing
Vestal Final Environmental Impact Statement Chapter 2

Maintained Meadow

MPB Infested Tree

MPB PItch Tube

Precommercial Thinning 

(PCT)

54* acres 

*Acres shown are those where PCT or POL 

are proposed as individual treatments. Both 

PCT and POL would also occur following

other treatments as noted. 

Understory thinning of trees that are 

less than 5” dbh to a spacing of 12 x 

12 feet. 

Pine Encroachment (PE)

1,458 acres

The objective is to maintain natural 

fuelbreaks by removing all conifers 

from existing meadows.

Sanitation (Sani)

3,655* acres 

*The acreage noted here pertains to pine stands 

deferred from other treatments. Pine stands 

deferred from other treatments include those 

already at a low risk for MPB, those which area 

important for wildlife cover or nesting habitat, and 

those which are too steep and rocky. 

Removal of green trees currently 

infested with MPB. This is a 

suppression method which directly 

removes MPBs from the forest. This 

treatment is included on all pine 

stands in the project area. 

Sanitation may occur for up to five 

consecutive years.
Vestal Final Environmental Impact Statement Chapter 2

22

Dead Fall-After

Dead Fall-Before

The vegetation treatments described above contribute to reducing fire hazard within the 

project area. Additional treatments that focus specifically on reducing fuels are also 

proposed and summarized below. Besides reducing fuels, prescribed fire would also be 

used to maintain openings near Buckhorn Mountain that were previously created under a 

separate project for mountain goat forage. 

Dead Fall (DF)

23,693* acres

*Deadfall is included on all pine sites in the 

project area. Actual acres would be dependent 

upon extent of MPB killed trees. 

Mechanical treatment of existing 

slash, resulting from MPB caused 

mortality, to a target height of 18” 

where possible, but no more than 24” 

from the ground. 

May include various methods but not 

limited to lopping, chipping, crushing, 

piling and burning, or mastication. 

No standing dead would be cut as part 

of this treatment. The objective of 

this treatment is to reduce the dead 

ladder fuels within these stands, thus 

reducing the potential for a wildfire to 

move into the crowns. 
Vestal Final Environmental Impact Statement Chapter 2

23

Fuel Break-Before

Fuel Break-After

Prescribed Burning-Before

Prescribed Burning-After

Fuelbreak (FB)

180 acres

Thinning of pine sites to reduce fire 

hazard adjacent to private lands by 

reducing stand density. 

Fuelbreak treatment would occur up to 

300 feet from private land boundaries. 

Trees up to 9” dbh would be cut to a 

residual tree spacing of 24’ x 24’. 

Residual slash would either be piled for 

burning, or include mastication of slash 

rather than piling and burning. This 

treatment is utilized in areas where no 

other treatment is proposed, or when 

proposed treatment does not sufficiently 

reduce fire hazard adjacent to private 

lands. 

Prescribed Burning (RX)

1,761 acres

Controlled application of fire to wildland 

fuels in either their natural or modified 

state under specific environmental 

conditions. Fire is confined to a 

predetermined area and produces the fire 

behavior required to achieve planned 

resource management objectives. 

Prescribed burning would establish and 

maintain a mosaic of vegetation conditions 

to reduce occurrences of catastrophic fire, 

and facilitate firefighting capability. 

Objective of this treatment is to reduce fire 

hazard by reducing surface fuels. In 

addition, RX would be used to maintain a 

total of approximately 35 acres of 

openings which provide forage for 

mountain goats on Buckhorn mountain. 

Prescribed burning would occur after 

mechanical treatments and following the 

MPB epidemic.
Vestal Final Environmental Impact Statement Chapter 2

24

Alternative 2 would produce approximately 85,750 hundred cubic feet (CCF) of 

commercial sawlog volume (42.875 MMBF) and approximately 33,054 cunits of POL as 

a byproduct of the mechanical treatments. Table 7 (page 32) summarizes Alternative 2 

treatments.

There are approximately 125 miles of Forest Service system roads in the project area. Of 

these roads, 48 miles are closed yearlong, 35 miles are open seasonally (May 15 to 

December 15), and 42 miles are open yearlong. In addition to Forest Service system 

roads, there are approximately 28 miles of County roads. The 2010 Forest Travel 

Management decision and associated Motorized Vehicle Use Map (MVUM) 

administratively closed all unauthorized roads in the project area (approximately 39 

miles) and prohibited all off-road motorized travel. 

The proposed action includes the following modifications to the transportation system in 

the project area: 0.6 miles of unauthorized road is needed for access and would be 

converted to system road then closed following use; 0.1 mile of new road construction is 

required to avoid private property; and 0.9 miles of system road would be closed to 

protect resources either with physical closures or gates (Map 8, Appendix A).

The law generally prohibits the harvest of even-aged stands before they reach their 

maximum growth rate [National Forest Management Act (NFMA), 16 U.S.C. 

1604(m)]. Exceptions in the law allow the harvest of individual trees, or even parts or 

whole stands of trees, before this time to thin and improve timber stands, and salvage 

damaged stands of trees (part m1 of the law). Further exceptions are allowed in order to 

achieve multiple-use objectives other than timber management (part m2). 

The proposed action would harvest some trees before the maximum potential growth rate 

of some stands in the project area have been reached. These harvest treatments are 

consistent with the exceptions provided in part m2 of the law, and include the 

following: precommercial thinning, commercial thinning, hardwood conversion or 

fuelbreak treatments. These treatments are proposed to meet the Forest Plan multiple-use 

objectives stated earlier in this analysis. Appendix E contains silviculture findings. 

Design Criteria

Design criteria include Forest Plan standards and guidelines, USFS Region 2 Watershed 

Conservation Practices (WCPs), Best Management Practices, and site specific design to 

avoid resource impacts. They are applicable and to be implemented as a matter of 

standard operating procedure for the proposed action. Design criteria are applied to 

protect resources and forest users. All activities proposed in this project, including any 

post-sale activities or monitoring, must implement these design criteria. A list of project 

design criteria is available in Appendix B.

Monitoring 

The Hell Canyon Ranger District is responsible for monitoring results and effects of the 

selected actions. The District would ensure that EIS and Record of Decision (ROD) 

direction including design criteria and any necessary mitigation measures are applied and 

carried out appropriately. Project and contract administrators would perform much of the 

project monitoring during project implementation. Other resource specialists would 
Vestal Final Environmental Impact Statement Chapter 2

25

monitor specific progress including application of design criteria and mitigation measures 

related to their resource of concern (See Appendix C). 

Alternatives Not Considered in Detail

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

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

were not developed in detail (40 CFR 1502.14). The HFRA Sec. 104(c)(1)(C)(i)(ii) 

specifies consideration of additional alternative(s) meets the purpose and need of the 

project. 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 outside the scope of the project, duplicative of the alternatives 

considered in detail, or determined to be components that would cause unnecessary 

environmental harm. Therefore, the following alternatives were considered, but 

dismissed from detailed consideration for reasons summarized below. 

• An alternative that includes a 1⁄2 mile portion of FSR 284.1E to be eliminated and 

a new road be constructed to connect FSR 284 to FSR 284.1E (within T3S, R3E, 

Sec 12). 

- The existing FSR 284.1E provides adequate access for project 

implementation and other access needs. There is an existing Right-OfWay (ROW) granted to the Forest Service on FSR 284.1E. Therefore it is 

not necessary to construct a new road and abandon the ROW to achieve 

project objectives and to provide access. This alternative would not 

contribute toward meeting the purpose and need for action. 

• An alternative that includes Free Selection treatment that retains an overall basal 

area that would be no higher than 60 BA. Including ‘islands’ within the sites that 

would be cut to no less than an 80 BA. Also, Sanitation treatments would occur 

in these ‘islands’ to treat MPB infested trees on an annual basis or until the 

current epidemic ends. 

- The Free Selection treatment is only proposed on approximately 4% of all 

treated pine stands in the project area. Other proposed treatments would 

reduce pine stand densities to 60 BA or less. Sanitation is included within 

sites proposed for Free Selection and other commercial treatments. 

Sanitation may occur for up to 5 years. Sites where Free Selection is 

proposed are those which have particular wildlife habitat elements. The 

proposed action reduces MPB risk to low on 87% of the project area. This 

landscape reduction of risk is expected to provide some protection to more 

dense stands identified as important to wildlife which are therefore, 

expected to withstand the MPB epidemic. 

• An alternative that treats sites 030303-01 & 030303-04 with Sanitation only. 

These sites are adjacent to Calamity Peak, a well-known landmark which holds 

high value for hiking and climbing. 

- The value of Calamity Peak as a hiking and climbing area is well known. 

The 2 noted sites are fairly large in size and occur on or adjacent to this 

Peak. Site 030303-04 is proposed as a Commercial Thin and site 030303-
Vestal Final Environmental Impact Statement Chapter 2

26

01 is on the north side of Calamity Peak and is proposed as a Group 

Shelterwood. Limitations to harvest capabilities, such as access, soils, and 

slopes, will dictate where activities may occur in these sites. Very small 

portions of these two sites will be accessible and feasible to treat, based on 

project design for soils and slopes. It is expected that only the periphery 

of these sites would be treated. Due to the very active MPB outbreak, and 

the location of these sites near private lands, reducing stand density and 

MPB risk is a main goal. 

• An alternative that includes non-conventional logging systems, such as tractor or 

skyline systems. These systems would allow for areas with slopes in excess of 

50% to be treated. 

- Generally, the inaccessible areas within the project area are due to large 

granite outcrops and peaks. Tractor logging may occur under the 

proposed action, although, the area is not conducive to skyline harvest 

systems due to the granite rock outcrops. 

• An alternative that includes: Individual Tree Selection, Group Selection, Group 

Retention, Hardwood Enhancement, Meadow Enhancement, Old Growth. 

- The proposed action includes treatments which maintain or enhance stand 

or landscape level diversity, including Free Selection, Variable Density 

Thinning, and Group Shelterwood. Hardwood enhancement (hardwood 

release) is included on all existing hardwood stands which contain 

conifers. Meadow enhancement (pine encroachment) is also included on 

all meadows that have conifers. The group retention treatment vastly 

opens stands and is not prescribed in this area due to the MPB epidemic 

which is actively reducing stand densities. Old growth is not a treatment 

type. There are currently 107 acres (<1%) of structural stage 5 (late 

succession) within the project area. Impacts to late succession are 

discussed in the EIS. 

• An alternative that treats all acres considered ‘high risk’ or ‘at-risk’ of being 

infested with MPB. An alternative that includes additional commercial treatment,

- Sanitation is included for all pine sites within the project area, either as a 

stand-alone treatment or in conjunction with other treatments. Sanitation 

only treatments are included in some stands where MPB risk is low or 

other resource concerns exist. Not all stands with high risk are proposed 

for treatments to low risk due to other resource concerns. 

• An alternative that includes increased Free Selection and Variable Density 

Thinning, and decreased Commercial Thinning, in order to reduce MPB risk and 

fire hazard while providing more vegetative and visual diversity. 

- Due to the existing conditions in this area, and the vast amount of private 

lands, reducing MPB susceptibility is a main goal. Experience has shown 
Vestal Final Environmental Impact Statement Chapter 2

27

that reducing the BA to 60 or less is an effective method of treatment. 

Free Selection and Variable Density Thinning is proposed in certain areas 

with specific wildlife habitat concerns. While these treatments would 

have a positive effect by reducing the overall BA, they are not as effective 

as standard Commercial Thins in reducing MPB susceptibility. 

• An alternative that includes harvest restrictions of the oldest and largest trees. 

With a main goal of saving these trees, as well as recruit replacements. 

- The purpose and need of this project would not be achieved is all old or 

large trees were restricted from harvest. The proposed action reduces 

susceptibility to MPB caused mortality and therefore, improves the 

potential for old and large trees to remain on the landscape. Each 

proposed treatment would retain some large trees. Overstory Removal, 

which generally is a removal of all overstory, includes design criteria to 

retain at least one large tree per acre. 

• An alternative that retains spruce within the following meadow sites: 030305-07, 

50, 70, 71, 72. 

- The proposed action includes Pine Encroachment treatment on these sites. 

Design criteria have been added to not remove any spruce from these sites. 

• An alternative that would include Variable Density Thinning in site 030305-38, 

rather than Commercial Thinning, to manage for stand diversity for goshawks. 

- The proposed action includes treatments which maintain or enhance stand 

or landscape level diversity, including Free Selection, Variable Density 

Thinning, and Group Shelterwood. Site specific design criteria are 

included in the proposed action to manage for goshawk habitat. Field 

survey for goshawk were conducted in the noted site and surrounding 

sites. 

• An alternative which would split the project into two separate projects, removing 

a portion of the project area which has been proposed by an interest group as the 

Okawita Paha National Monument and International Peace Park. 

- There is no National Monument in the project area. There is no indication 

that any portion of the project area is being considered by the President for 

designation as a National Monument under the Antiquities Act. 

Therefore, such as designation is not reasonably foreseeable. 

Comparison of Alternatives

This section provides a comparison of the two alternatives analyzed in this EIS. The 

alternatives are described and compared in terms of the effects each has on the project 

area. Appendix A, Maps 6-7 show vegetation treatments. The environmental 

consequences of the alternatives are described in detail in Chapter 3 of this EIS. 

The existing condition acreages used in the tables below represent conditions in year 

2011. Alternative conditions are projected to year 2018 because that is when project 
Vestal Final Environmental Impact Statement Chapter 2

28

actions are expected to be substantially complete and when the MPB epidemic is 

predicted to have run its course in the project area.

Table 3 shows the changes in cover types between the existing condition and the two 

alternatives. The only differences are in acres of aspen and ponderosa pine, as 126 acres 

of hardwood conversion are proposed. All other cover types would remain unchanged.

Fire Hazard is defined as a combination of fire risk, fuel condition, weather, and 

topography. Fire risk is based on the potential for a fire to start in a given area. Fuel 

conditions are based on quantity, arrangement, and sometimes live to dead ratios. The 

Forest Plan bases fire hazard ratings for the Black Hills on ponderosa pine structural 

stages. Table 6 compares fire hazard rating between alternatives. Structural stages (SS) 

used to determine fire hazard ratings are as follows:

Low = SS1 

Moderate = SS2, SS3A, SS4A (>9”avg. diameter)

High = SS3B, SS4B (>9”avg. diameter) 

Very High Risk = SS3C, SS4A (<9”avg. diameter), SS4B (<9”avg. diameter), SS4C,

CHAPTER 3: AFFECTED ENVIRONMENT AND 

ENVIRONMENTAL CONSEQUENCES

This section summarizes the environment of the affected project area and the potential 

changes to those environments due to implementation of the alternatives. It also presents 

the scientific and analytical basis for comparison of alternatives presented in Chapter 2. 

The information presented here is based on analysis prepared by resource specialists from 

the interdisciplinary team (IDT) and pertains to National Forest lands only, unless 

otherwise noted. Analysis was accomplished by field observations and surveys, past 

experience and professional recommendations, aerial photography, resource modeling, 

literature review, information obtained through monitoring, Forest Plan direction and 

associated analysis, and public participation. The specialist reports are included in the 

project file, which is located at the Black Hills National Forest, Hell Canyon Ranger 

District, 330 Mount Rushmore Road, Custer, South Dakota. All resource specialists used 

the best available science in completing their analysis, in accordance with Forest Service 

Manual (FSM) 1920. 

Past, Present, and Reasonably Foreseeable Actions 

Analysis of cumulative effects include past, present, and reasonably foreseeable future 

activities that could affect the biological or social environments. See Appendix F for a 

listing of past, present, and future activities considered in the Vestal project cumulative 

effects analysis. The project area boundary was used to address cumulative impacts, 

unless otherwise noted in the resource discussions. Rationale for cumulative effects 

boundaries is noted in the cumulative effects discussions by resource. 

Forest Vegetation

Affected Environment

Cover Types

Vegetation in the Vestal project area is dominated by ponderosa pine cover type (92%), 

but also includes aspen (2%) and spruce (<1%) forested types. Aspen also occurs as 

small inclusions within some pine stands. The project area also contains a minor amount 

of non-forested cover types. Non-forest cover types currently occupy approximately six 

percent of the project area. These areas are mostly grasslands, but include rock and water. 

Table 11 displays acres and percentages of cover types in the project area.

Ponderosa Pine

Ninety-two percent of the project area is vegetated by the ponderosa pine cover type 

(Table 11). The majority of the project area is densely-stocked mature ponderosa pine. 

Much of the current tree cover originated with the beginning of extensive fire 

suppression. As a result of past management activities, natural disturbances such as 

wildfire and endemic mountain pine beetle activity, some structural stage diversity and 

vegetation diversity exists. The current mountain pine beetle infestation in the project 

area threatens to transform much of the area into structural stages 1 and 2 (Allen 2011).

Management Areas 4.1, 5.1 and 5.4 have structural stage objectives (Objectives 4.1-203, 

5.1-204, and 5.4-206 respectively) within the ponderosa pine cover type. The objective 

percentages are the same for each management area and are displayed in Table 13. This 

objective applies to the entire management area, not the project level.

Very Large Sized Trees

These same MA objectives also state: “10% of the structural stage 4 ponderosa pine 

acreage in the management area will have an average tree size of very large. Again, this 

applies to the whole management area, not the project area. Table 17 displays current 

percentage of SS4 pine acreage with an average tree size of very large within each

management area, per the 2009 Black Hills Monitoring and Evaluation Report (USDA 

Forest Service 2010). Based on this data the objective is currently exceeded in MAs 4.1 

and 5.1 and is near achievement in MA 5.4. 

Table 17. Existing Percentages of Very Large Sized Pine Acres by Management Area

Forest-Wide MA 

Objective MA 4.1 - Existing MA 5.1 - Existing MA 5.4 - Existing

10% 20% 13% 9% 

The Vestal project area contributes to these forest-wide percentages. Currently, there are 

approximately 974 acres of SS4 pine which have an average tree size of very large in the 

Vestal project area. These stands are located in all three of these management areas. 

There are approximately 50, 208 and 716 acres of pine stands with an average tree size of

very large in MAs 4.1, 5.1 and 5.4, respectively. 

Late Succession

Late succession, or structural stage (SS) 5, is defined in the Forest Plan glossary as 

follows: “This structural stage is characterized by very large trees (16+ inches dbh). 

Trees are at least 160 years in age....Late succession ponderosa pine may occur in dense 

stands, but may also grow in the open or in park-like stands” (Mehl 1992). 

Forest Plan direction for SS5 is included in the management area objectives, as discussed 

earlier. The Vestal project area contains approximately 107 acres of identified late 

succession (SS5) pine forest in the project area and contributes to the existing forest-wide 

percentages for MA’s 4.1, 5.1 and 5.4. Late succession forest is at high risk for MPB 

infestation and a very high fire hazard rating. 

Currently there are approximately 10,267 acres of SS4B and approximately 2,700 acres 

of 4C in the project area; these stands would be available to grow into older, denser late 

successional stands. These stands would also be susceptible to morality from MPB 

infestation and wildfire. An additional 1,270 acres of SS3B (low MPB risk) would also 

be available to grow into SS5 stands in the future as additional replacement stands. 

Mountain Pine Beetle

There is currently a mountain pine beetle epidemic occurring within the project area 

(USDA Forest Service 2011b, also Appendix H). All measures of beetle activity indicate 

a rapidly exploding beetle situation with a significant increase in tree mortality over the 

past three years (Allen 2011a). Stand conditions across the project area are largely (61%) 

at high risk to increasing mountain pine beetle caused mortality (Table 18). Combine the 

high stand hazard with the high risk of a large resident beetle population in place would 

indicate that tree mortality is going to keep increasing and likely increase at a rapid level.

For a dramatic depiction of how quickly MPB caused mortality is occurring in this 

project area refer to the two pictures on page 2, Chapter 1, which dramatically display 

changes over a two year period. 

Tree mortality from mountain pine beetle is most evident in the northern and western 

portions of the project area, at this time. Field surveys completed in the fall of 2011 

indicate that approximately six trees were infested by MPB in 2011 for every single tree 
Vestal Final Environmental Impact Statement Chapter 3

37

attacked by MPB in 2010. These conditions signify a rapidly growing outbreak in this 

area (Allen 2011a). Refer to Map 11 in Appendix A for a depiction of the progression of 

this epidemic since 2005. Map 11 was generated from aerial surveying. 

The risk of mountain pine beetle infestation is predicted from pine structural stages. The 

Black Hills National Forest Insect Rating Guide (revised August, 2011) identifies risk as 

either High or Low, as summarized in Table 20. 

Table 18. MPB Risk Rating by Pine Structural Stage

Structural

Stage

Insect

Rating

1 Low

2 Low

3A Low

3B Low

3C High

4A Low

4B High

4C High

5 High

Based on this guide, currently, there are approximately 14,373 acres of ponderosa pine at 

high risk for mountain pine beetle infestation in the Vestal project area (See Map 12 in 

Appendix A). This is about 61% of the pine stands in the project area. High-risk pine 

stands are at a greater potential for increased MPB activity. Most of the mortality is in 

trees that are greater than 7-inches in diameter, with lesser amounts in smaller trees. 

Mortality is also typically concentrated in stands where tree density is highest, typically 

over 100 basal area (Allen 2011a). Stands above 60 ft2/ac of basal area or higher 

(generally SS 3C, 4B, 4C and higher density 4A stands) are considered to be at high risk. 

Table 19 displays existing MPB risk ratings. 

Table 19. Current MPB Risk Rating for Ponderosa Pine in Vestal

Mountain Pine 

Beetle Risk Acres Percentage

Low 9,320 39%

High 14,373 61%

Hardwoods

There are 431 acres (~2%) of designated aspen stands within the analysis area. These 

stands are scattered throughout the project area, but mainly occur in the northern and 

eastern portions (see Map 3 in Appendix A). Hardwoods, mainly aspen, can also be 

found growing as inclusions within some conifer stands in the project area. Aspen is 

often out competed by intruding conifers. 

Spruce

White spruce is shade tolerant; enabling regeneration and growth under closed forest 

canopies and grows slower than ponderosa pine (Sheppard & Battaglia 2002). In the 

absence of stand replacing events (e.g., fire, insects) and vegetative treatment, there is 

potential for spruce communities to increase. However, due to its thin bark and low 
Vestal Final Environmental Impact Statement Chapter 3

38

branches, it is susceptible to fire mortality. Currently there are 42 acres of designated 

spruce stands in the project area. These areas are generally located along north facing 

slopes and on moist micro-sites. Mixed spruce and pine stands occur in the project area as 

well. Stringers of spruce also occur within some meadow sites. 

Meadows 

There are 1,482 acres (6%) of meadows in the Vestal area. Many of these meadow sites 

have been encroached by conifers. Grassland and meadows have increased from 2008 to 

2009 forest-wide (USDA Forest Service 2010).

Environmental Consequences

This section compares the two alternatives at year 2018, when all management activities 

are expected to be completed and the mountain pine beetle infestation is expected to have 

run its course in the project area. 

Alternative 1- No Action

This No Action alternative is predicted to result in changes on the landscape due to the 

effects of MPB. Therefore, all predicted effects noted here under Alternative 1 are a 

result of MPB caused tree mortality. 

Cover Types

The acreage and percent of cover types within the project area are not predicted to change 

under this alternative by year 2018. In the long term, there could be an increase in 

hardwoods as overstory pine is killed by MPB, in areas where aspen is present in the 

understory. 

Ponderosa Pine

Under this alternative, no new forest vegetation activities would occur in the project area. 

However, the project area would still experience change through other processes. The 

most prevalent process affecting the project area is the current MPB infestation. The 

distribution of ponderosa pine structural stages within the project area would experience 

great change due to the current MPB infestation (Table 20). This change would move the 

project area away from Objectives 4.1-203, 5.1-201, and 5.4-206 by creating large areas 

of ponderosa pine structural stages 1 & 2, and by eliminating most of SS4B and virtually 

all of SS4C.

Estimates of MPB caused mortality were projected by the Forest entomologist (Allen

2011a) based on existing conditions in the project area, high populations of beetles and 

predominantly high (61%) MPB risk ratings. Field surveys of MPB activity in the fall of 

2011 confirm a rapidly increasing MPB outbreak in this area (Allen 2011a). The specific 

sites on where these structural stages would occur is speculative. Therefore, the total 

acres and percentages of projected structural stages are presented for comparison. 

The population of mountain pine beetles would increase at a greater rate because high 

risk stands would continue to exist and be available for infestation. As the population 

continues to increase at an epidemic rate more trees in low risk stands would also be 

attacked. Landscape scale changes in forest structure would occur with vast areas reduced 

to SS 1, 2, and 3A. These changes have been seen in previous outbreaks across the forest. 

Infested trees would undergo the effects of blue stain fungus which would lower the 

commercial value of the wood. Wood borers and weather checking would render much of 

the wood useless for commercial purposes within one year. Vast areas would be reduced 

to a level below the timber management zone (Stocking charts in Appendix H of the 

Forest Plan-see Guideline 2409). Structural stage 1 and other low density stands would 

take decades to reforest due to long distances between residual trees. Stands designated 

for goshawk and late successional habitat would likely be lost as tree mortality alters their 

structural stages and thus destroys the characteristics they have been designated for. 

Trees killed by MPB tend to fall or break within 3-5 years. Standing dead and fallen dead 

trees would create heavy concentrations of fuels causing large areas to be at high hazard 

for large scale high intensity wildland fires which could threaten other forest resource 

values. Private forest lands mixed in the project area would be subject to the same threat 

and loss of resource and habitat values. 

This alternative would not treat any acres to a low insect rating. The percentage of the 

ponderosa pine stands in the analysis area in SS 3B, 3C, 4B, and 4C would go from 66% 

to 10% (Table 21). The high population of MPB attacks and resulting mortality not only 

affects the largest trees, but also smaller trees down to 3-inches dbh. In general, the more 

dense stands would be changed to less dense and early successional stands. 

Approximately half of these sites would change to SS1 and SS2. Single-storied sites 

lacking advanced regeneration would change to SS1, while multi-storied sites with 

advance regeneration would change to SS2 (Table 21). The unpredictable nature of MPB 

caused mortality at a small scale prevents predicting the site specific location of structural 

stage changes. 

Structural stage changes projected to occur with Management Areas 4.1, 5.1 and 5.4 are 

presented below in Tables 21-23.

Very Large Sized Trees

Due to MPB caused mortality the No Action alternative would reduce the acres of SS4 

with an average tree size of very large within the project area by approximately 67% 

from 974 acres to 324 acres (Table 24). This change in acres would not result in a 

change to the Forest-wide management area percentages (Table 25). Objectives 4.1-203 

and 5.1-204 would continue to be exceeded. Objective 5.4-206 would retain its 

percentage, but actually moves away from the objective based on acres.

Late Succession

Total acres of late succession are expected to be reduced in this alternative due to MPB 

caused mortality. Approximately ten acres of late succession (SS5) are projected to 

remain within the project area at year 2018 (Allen 2011). The remaining SS4A and SS4B 

stands could eventually grow into SS5; however this would take several decades or 

longer to achieve. With the current MPB infestation it is highly likely that the 

development of SS5 would be delayed due to an increase in MPB caused tree mortality. 

Hardwoods

Aspen would benefit from the mountain pine beetle-caused mortality of overstory 

ponderosa pine, which decreases competition for sunlight and nutrients. However, 

ponderosa pine less than 3” dbh would escape mortality and remain to compete with 

quaking aspen. The pine would eventually shade out the aspen within the subsequent 50 

years. Increased sunlight warming the ground would immediately stimulate aspen 

regeneration through root suckering, expanding existing clones outward a distance up to 

1 to 1.5 tree heights (Shepperd & Battaglia 2002). The flush of new aspen suckers 

increases browsing damage, however, the large amount of ponderosa pine snags falling 

down mitigate the browsing pressure by physically blocking deer and elk from the 

suckers. This alternative would move toward Forest Objective 201. 

Spruce

This alternative would not have any direct effects on spruce. Indirectly spruce may 

increase in time due to dense canopy conditions (stands not affected by MPB) and fire 

suppression. Dense mixed conifer stands would likely lose the ponderosa pine 

component to MPB caused mortality. The loss of ponderosa pine could affect the 

structure of spruce stands by increasing wind-throw (spruce are highly susceptible to 

wind throw), coarse woody debris, and subsequent ladder fuels. . 

Meadows 

Meadow sites in the project area would continue to experience encroachment from 

ponderosa pine. The ponderosa pine encroaching on meadow sites is either not large 

enough or dense enough to experience heavy mountain pine beetle-caused mortality. 

Meadows are not expected to increase as their extent is limited by soil characteristics. 

This alternative would not impact achievement of Objective 205. 

Alternative 2

Cover Types

The proposed action includes 126 acres of hardwood conversion. These stands were 

identified as past aspen sites which had been encroached by pine over time. 

This treatment would result in an increase of 126 acres in aspen and a corresponding 

decrease in ponderosa pine cover types. No other changes to cover types are anticipated 

in the proposed action. 
Vestal Final Environmental Impact Statement Chapter 3

43

Ponderosa Pine

Effects to pine structural stages from vegetation treatments would be expected to move 

away from the Forest Objectives for structural stages by management area, but not as 

much as in Alternative 1. Conifer sites treated to SS3A and SS4A or those already in 

SS3A or SS4A can be expected to survive the MPB infestation and grow into SS3B and 

SS4B within 20 to 30 years.

This alternative would create more SS4A than Alternative 1, but would also retain more 

dense stands and mature stands as SS3C, 4B, 4C and 5 (Table 26).

*Pine acres are reduced in Alternative 2 as 126 acres are converted to aspen.

The MPB epidemic is currently threatening forest resources in the project area. 

Vegetation treatments in Alternative 2 are designed to reduce MPB susceptibility thereby 

reducing the potential for MPB caused mortality. Reducing the density of high-risk 

stands to a basal area of 60ft2/acre or less would reduce the risk of MPB susceptibility to 

Low. In areas where there are ongoing beetle epidemics, lowering stand densities to 

60ft2/acre provides a higher level of prevention (Allen 2011a). Approximately 20,000 

acres of treatments are proposed within pine stands. A follow up Products Other than 

Logs (POL) thinning of trees under 9” dbh to a 20’ by 20’ spacing would also be done 

where the commercial sawtimber harvest (selected trees over 9” dbh) does not remove 

enough trees to reach the 60ft2/ac. objective.

Some stands adjacent to private lands would be thinned to 50ft2/acre for crown fire 

hazard reduction. A follow up POL thinning of trees under 9” dbh to a 22’ by 22’ spacing 

would also be done where the commercial sawtimber harvest (selected trees over 9” dbh) 

does not remove enough trees to reach the 50ft2/ac objective. 

Conversely, some stands would be left at higher density for wildlife habitat needs or as a 

result of slope and access concerns. These stands are proposed for sanitation cutting only 

(3,655 acres). Such stands would be at a high risk of infestation but reducing risk around 

these stands would provide some protection, and these stands are projected to remain on 

the landscape. Sanitation, removal of trees currently infested with MPB, is a suppression 

action and would be applied to all forested stands. It would generally be accomplished at 

the same time as other stated mechanical treatments. Sanitation cuts would effectively 

remove insect broods from the forest and destroy the insects. This treatment would 
Vestal Final Environmental Impact Statement Chapter 3

44

reduce the potential spread of MPB to forested stands on private land as well as National 

Forest. Sanitation cuts would be done for up to five years in each stand if necessary to 

remove newly infested trees. The proposed action acknowledges the fact that no amount 

of treatment would completely eliminate the threat of MPB infestation, however 

treatments such as those in the proposed action, would reduce that threat more than the 

No Action alternative. 

All commercial entries would be limited by operability and access limitations resulting in 

something less than the total acres planned being actually treated with commercial 

harvest. This would amount to no more than 12% of the planned commercial treatment 

acres.

The result of this alternative is a lowered risk level and a decreasing level of MPB caused 

mortality relative to the current epidemic (Table 29). The landscape is expected to 

encompass thinned stands, some very open stands, and some openings as a result of the 

varying levels and concentrations of infested trees. Aspen clones would increase in size 

and viability as conifers are removed in and around them. As the infestation is slowed in 

the treated stands, areas left at higher densities for wildlife habitat would be more likely 

to avoid levels of mortality that reduce their structural stage condition. 

Prescribed burning has little effect on the site structure following mechanical treatments 

that create SS 3A or 4A. However, prescribed burning in combination with drought can 

stress residual trees in mechanically-treated areas and leave them susceptible to mountain 

pine beetle-caused mortality. Therefore prescribed burning would be delayed until after 

mechanical treatments are completed and following the passing of the mountain pine 

beetle epidemic.

Thinning treatments would increase growth on remaining trees and improve the overall 

health of the stands because there would be more water, nutrients and sunlight for each 

tree. Thinning can put stands at risk to windthrow and breakage, particularly where 

drastic changes in density result. The potential for windthrow and breakage would be 

minimized by thinning from below, i.e. harvesting mostly the smaller, shorter trees and 

leaving the tallest trees that have had more wind exposure and developed more 

sturdiness. This alternative would not be expected to result in a marked increase in 

windthrow or breakage and it would be less than in Alternative 1. 

Managed healthy stands would maintain options for future forest management. Some 

reproduction of seedlings can be expected over time after thinning. This change in forest 

structure may be treated in future entries with prescribed burns or mechanical treatments 

to eliminate seedlings. Conversely, overstory removals, regeneration cuts or uneven-aged 

treatments may be prescribed to enhance or maintain the diversity in structure that is 

developed.

the project area, by approximately 21% from 974 acres to 767 acres (Table 31), which is 

less of a change than in Alternative 1. This change in acres however would not result in a

Late Succession

The proposed action alternative would not treat any late succession stands. Sanitation is 

included, if needed, but this would not alter the structural stage. Therefore, there would 

be no direct effects to late succession. Indirectly, this alternative would retain more 

mature and dense stands (SS3C, 4A, 4B and 4C) that could eventually grow into SS5 

over several decades or longer. The potential to develop SS5 is improved over the No 

Action alternative. Reducing the risk for MPB caused mortality in the surrounding 

landscape would improve the potential for these late succession stands to remain. 

Hardwoods

In this alternative, acres of aspen would be increased from an existing 431 to 557 acres. 

All conifers would be removed from existing hardwood stands and an additional 126 

acres of ponderosa pine cover type would be converted to a quaking aspen cover type 

following treatment. The intolerant hardwoods cannot compete with the more tolerant 

conifers. Removing all conifers from a hardwood stand would ensure that hardwoods 

would not become shaded out and the stand eventually taken over by conifers. This is 

consistent with forest plan standard 2205. In addition, scattered inclusions of aspen 

within pine stands would be released from competition by having conifers removed. A 33 

foot buffer around each aspen inclusion would also have conifers removed to allow 

sunlight to the aspen and enhance further expansion of the aspen inclusion. Conifers less 

than 9” dbh would be hinged and left on site to protect aspen suckers from browsing. 

Hinging is an effective method to deter browsing in the Black Hills (Kota & Bartos 

2005). This alternative better moves toward Objective 201, than Alternative 1. 

Spruce

There are 107 acres of white spruce in the project area within three of the four 

management areas. White spruce is rare on this landscape and in healthy condition at this 

time. No treatment within the spruce stands would occur with this entry except for 

Sanitation as needed to remove MPB infested pine trees.

Meadows 

Approximately 1,458 acres of pine encroachment treatments would occur in historic 

meadow sites. These historic meadow sites have been encroached upon by pine. They 

would be restored by removal of conifers of all sizes. As a result, increased grass and 
Vestal Final Environmental Impact Statement Chapter 3

48

forage production would occur. This alternative better moves toward Objective 205, than 

Alternative 1.

Cumulative Effects

The time boundary used to analyze cumulative effects is 1980-2018. Harvesting and 

noncommercial treatments in the 1980s are the earliest known activities that still 

significantly affect the landscape today. The timber sales from this analysis are 

scheduled to sell in 2012 and 2013. Allowing two years for the sales to be harvested and 

three years for post-sale activities to be accomplished all activities should be completed 

by approximately 2018. Predicted changes in structural stages from mountain pine beetles 

would also be expected to occur by 2018. 

The spatial boundary used to analyze cumulative effects is the project area boundary for 

all resource elements discussed in this section except for mountain pine beetle. The 

direct and indirect effects for most elements are contained within the project area 

boundary. The cumulative effects boundary for mountain pine beetle is the project area 

and the Wabash Resale Timber Sale area immediately adjacent to the southwest boundary 

of the project area. This boundary was selected because beetle populations are known to 

be at a high level in the Wabash area and could affect ponderosa pine within one mile of 

this sale area. Beetles generally move less than one-tenth of a mile per year but might 

travel up to several miles on rare occasions.

Much of the Vestal analysis area has been harvested in the past. At least 25 timber sales 

have taken place in portions of the project area since 1980. The effect of past treatments 

has been an increase of merchantable volume growth and improvement in the quality of 

timber. There has also been an improvement in the quality of timber through removal of 

damaged, diseased, and poorly formed trees. Precommercial thinning and weed & 

release have occurred and improved stand health by removing damaged, diseased, and 

poor quality trees. Past treatments have contributed to the current structural stage 

conditions. 

Some timber harvesting is occurring on private land within the project area, mostly in 

conjunction with MPB and fuels reduction. Since private land comprises approximately 

40% of the project area (17,693 acres) and over 7,000 acres of that is forested land, the 

effects of treatment on private land for fire hazard reduction and MPB would contribute 

to a reduction in both fire hazard and MPB risk. 

Late Succession and Very Large Sized Trees

Past timber harvest has had both positive and negative impacts on late succession and 

very large sized trees. It has allowed some mature trees to grow into the very large tree 

size (greater than 16+ inches dbh) by increasing diameter growth as a result of less 

competition. In addition, MPB risk to mature stands has been reduced due to harvest. 

Past harvest has also removed old trees from stands that may have had the potential to 

become late succession.

The proposed action alternative would have a beneficial cumulative effect by increasing 

the potential for retention of very large and old trees on the landscape because of reduced 
Vestal Final Environmental Impact Statement Chapter 3

49

MPB risk on both National Forest and private lands. The No Action alternative would 

not reduce MPB risk and therefore would not have a beneficial cumulative effect.

Mountain Pine Beetle Risk

The Black Hills, including the Vestal analysis area, has recently emerged from a 10 year 

on-going drought condition. While MPB does not depend on drought conditions for the 

insect to continuously increase their population, the drought has aided the MPB by 

increasing stress in healthy trees thus making the trees more vulnerable to a successful 

insect attack.

With the No Action alternative, lack of vegetation treatment within pine sites would 

increase the potential for MPB populations to increase within the project area. Pine sites 

near the most highly infested areas to the north and east and the Wabash Resale Timber 

Sale would be expected to become affected first. Sites to the south have numerous small 

infested patches and are probably a year behind in intensity of infestation. The No Action 

alternative would therefore have an adverse cumulative effect on ponderosa pine as 

related to MPB infestation.

There would be positive cumulative effects to MPB risk under the proposed action 

alternative. Treatment of pine stands to a lower stand density reduces the susceptibility 

of a stand to MPB infestation. Sanitation reduces beetle populations by removing infested 

trees. These actions have occurred on National Forest lands within the project area in 

small sales such as Atlantic Bug, Tenderfoot Bug, and Quincy Bug and also on adjoining 

lands. These effects would not only benefit National Forest lands but privately owned 

land as well. Treatments to reduce MPB risk on private lands are occurring including 

thinning, sanitation and cutting and chunking of infested trees. Treatments to reduce 

MPB risk are also occurring on other lands adjacent to the project area (State, other 

Federal). Cutting and chunking is occurring throughout the project area. All of these 

actions would have a positive cumulative effect to MPB risk when added to the 

treatments proposed in Alternative 2. Past and present activities combined with the 

proposed activities would result in a decreased potential for mountain pine beetle-caused 

mortality on all ownerships. 

With an increasing interest from private land owners to treat their forested land and 

protect it from MPB infestation and fire hazards, and clearing land for home sites, it is

anticipated that future treatments would occur. Treatments on private land for MPB 

infestation and fire hazard reduction would contribute to the overall reduction of both fire 

and MPB risk throughout the project area. 

Hardwoods

Past treatments have removed conifers from almost all hardwood stands. This action has 

prevented hardwoods from becoming shaded out and the stands eventually being taken 

over by conifers. 

Under No Action, the aspen stands and scattered inclusions of aspen within pine stands 

would not be released from competition by having conifers removed. However, MPB 

caused mortality is expected to reduce pine overstory and would release aspen where they 

occur in the understory of stands. The proposed action alternative would release aspen 

stands and inclusions from conifers. Trees killed by MPB typically break or fall within 
Vestal Final Environmental Impact Statement Chapter 3

50

3-5 years and would provide a hindrance to grazing of aspen. Mountain pine beetle 

caused mortality on other ownerships would have a similar effect. A positive cumulative 

effect is expected for aspen under either alternative. 

Spruce

The MPB epidemic may benefit spruce over time by reducing competition from pine. . 

No treatments for spruce are proposed in the alternatives and none are known on private 

lands either.

Meadows 

Some meadows have been successfully released from pine competition in the past on 

both National forest and private lands. Grazing occurs on many private meadows as well 

as Forest service meadows and contributes to meadow maintenance. Approximately 

1,458 acres of pine encroachment removal would occur in the proposed action 

alternative. These are historic meadow sites which have been encroached upon by pine. 

They would be maintained by removing conifers of all sizes. As a result, increased grass 

and forage production would occur. 

Mountain pine beetle may reduce pine in meadows, generally trees >7” dbh. The smaller 

trees are not expected to be killed by MPB. The cumulative effect under No Action 

would be that pine would remain in these meadows and seed more trees further into the 

meadows. Grass and forage production would continue to decrease. 

Wildlife and Fish

Affected Environment

Existing vegetation habitat conditions are discussed under the ‘Forest Vegetation’ section 

in this document. Additional discussion of some specific habitat components, snags and 

down woody material is presented below. Riparian ecosystems are discussed in the 

Hydrology section. 

Snags and Down Woody Material

The MPB outbreak that has been occurring for the last 3-4 years has created snag habitat 

in the Vestal Project Area, especially in the northern and western portion of the project 

area. However, trees killed by MPB are only expected to remain intact on the landscape 

for about 5 years (Schmid et al. 2009). 

Currently, cutting snags for fuelwood is allowed within 300’ of roads where dispersed 

camping is permitted as shown on the Forest Motorized Vehicle Use Map (MVUM). The 

majority of the Vestal project area is included. No other snag cutting areas occur within 

the project area. 

Down woody material amounts vary across the project area. Most of the project area 

currently contains down woody material at levels noted in Objective 212. 

Management Indicator Species (MIS) 

The Phase II Amendment to the 1997 Forest Plan-FEIS (USDA Forest Service 2005a) 

lists MIS to be considered during project-level planning. The MIS species which have

Beaver (MIS)

The beaver was selected as a Forest MIS to evaluate the effects of Forest Plan

implementation and natural change on the ability of the Forest to support species that rely 

on a variety of riparian and hardwood forest conditions to meet their needs (USDA Forest 

Service 2005a). 

In the project area, there is an active colony at Bismarck Lake; another active colony is 

close to the project area up Sylvan Lake Road. 

Baseline beaver surveys were conducted on the Forest in the fall of 2004. The species 

was most commonly found in the Bearlodge Mountains and central Black Hills (USDA 

Forest Service 2005b). Forest-wide, long-term beaver population trend has increased 

since heavy trapping has decreased, but it is less than its potential. The current 

distribution of beaver is reduced based on the number of inactive beaver sites that were 

observed (during monitoring efforts in 2007), especially in headwater streams, where 

water and/or a suitable food supply is lacking (USDA Forest Service 2008). In addition, 

Forest-wide, the long-term trend in beaver habitat is one of decline. The reduction in 

beaver activity that occurred from heavy trapping likely caused a lowering of water tables 

and a subsequent loss of willows and other riparian vegetation (Parrish et al. 1996). This, 

in conjunction with other factors, has reduced the quality and quantity of riparian willow 

habitat in the Black Hills following European settlement. The amount of aspen and other 

hardwoods on the Forest has also declined (USDA Forest Service 2005b). 

White-tailed Deer (MIS)

White-tailed deer were selected as a Forest MIS to evaluate the effects of Forest Plan

implementation and natural change on the ability of the Forest to support species that rely 

on a variety of forest conditions, including the presence of understory shrubs, to meet 

their needs (USDA Forest Service 2005a). 

White-tailed deer in the Black Hills require a diversity of habitat types. Juxtaposition 

between cover and forage is crucial year-round. Hardwood stands, which provide 

abundant forage combined with screening cover, were best predictors of white-tailed deer 

diurnal, summer use (Stefanich 1995). Peak use of dense aspen habitats with dense, tall 

shrub cover indicated importance as fawning habitat in the northern and central Black 

Hills (DePerno et al. 2002). Summer nocturnal habitat use is significantly different with 

use of open habitat types of meadows, riparian areas, and/or open pine relative to 

proximity of dense cover (Stefanich 1995). Wet meadows, riparian areas, and open 

stands of ponderosa pine also provide quality forage. Management actions that increase 

habitat and structural diversity across the Forest would better meet necessary forage and 

cover requirements for deer. The primary limiting factor for white-tailed deer in the 

Black Hills may be a lack of desirable shrubs for food and cover (DePerno et al. 2002). 

Another factor that can affect deer habitat is road construction and road density (SAIC 

2003). 

Habitat trend at the Forest-level suggests that summer habitat trend is increasing, and 

winter habitat trend is stable to slightly decreasing (USDA Forest Service 2005b). The 

Forest is meeting Objective 238a, with regard to summer habitat, but the Forest may not 

be maintaining winter habitat, although the decline might not be significant (USDA 

Forest Service 2009). 
Vestal Final Environmental Impact Statement Chapter 3

53

During field surveys, deer were often observed throughout the project area. The high 

amount of meadows (mostly on private land) and SS4A pine stands have provided areas 

for foraging, although shrubs are lacking in Vestal. Also, much (42%) of the project area 

is in big game winter range, which contains seasonal motorized use closure areas. The 

project area contains approximately 2.2 mi/mi2 of roads (includes Forest Service and 

county roads), with open road density at approximately 1.5 mi/mi2. In Management Area 

5.4 (Big Game Winter Range) only, road density is higher at approximately 5 mi/mi2. 

However, seasonal road closures from December 15-May 15 reduce open road density 

during this time to approximately 2.2 mi/mi2

. 

Big Game Screening 

Hiding or Screening cover is defined as: being able to hide 90% of an adult deer or elk 

from human view at a distance of 200 feet or less. There are 12 collector and arterial 

roads in the Vestal project area where the screening cover guideline (Guideline 3203) 

applies. Currently adequate screening cover is provided by vegetation or topography on 

all collector and arterial roads (Table 34).

Golden-crowned Kinglet (MIS)

The golden-crowned kinglet was selected as a Forest MIS to evaluate the effects of Forest 

Plan implementation and natural change on the ability of the Forest to support species 

that rely on a variety of conditions in spruce habitat to meet their needs (USDA Forest 

Service 2005a). 

Habitat for the golden-crowned kinglet has increased over the long-term and is exceeding 

the Forest-wide target of 20,000 acres (Objective 239) (USDA Forest Service 2010). 

Forest monitoring results show that kinglet relative densities were highest in 2005 (white 

spruce) and showed the lowest densities in 2007. Relative densities rebounded in 2009 in 

both late successional and white spruce habitats (USDA Forest Service 2010). Goldencrowned kinglets were also found in northern ponderosa pine, montane riparian and 

foothill riparian habitats; however, white spruce was present at some level within each 

one of these (Beason et al. 2006). 
Vestal Final Environmental Impact Statement Chapter 3

54

There are currently only 42 acres of designated spruce stands in the project area. Spruce 

also occurs within some pine and meadow sites, which would also be used by this 

species.

Black-backed Woodpecker (R2 Sensitive Species and MIS)

Black-backed woodpeckers were selected as an MIS to evaluate the effects of Forest Plan

implementation and natural change on the ability of the Forest to support species that rely 

on mature and late successional forest, burned forest, insects, and snags to meet their 

needs. The black-backed woodpecker is also a Region 2 (R2) sensitive species. The 

effects to this species are evaluated in the Biological Evaluation. 

Overall, habitat for this species is being provided consistent with Objectives 221 and 

238b. The “aging” of large burned areas into habitat less suitable for black-backed 

woodpeckers is likely being offset by the increasing acreage of insect-infested timber 

stands. Although ponderosa pine is the typical nest tree in the Black Hills, Bonnot et al. 

2009 also reported black-backed woodpecker nests in live and dead aspen. 

Black-backed woodpecker relative densities (birds/km2

) in burned habitat reached a high 

in 2002 and declined thereafter until 2009 when it reached the highest density. The jump 

in relative density in 2009 could be from the abundance of insect activity occurring 

across the Forest (USDA Forest Service 2010). The Forest-wide relative density for this 

species is probably higher than “normal” given the current habitat conditions. Blackbacked woodpecker populations are “eruptive” as reflected in their densities in burned 

habitat. This pattern of rapid colonization and subsequent decline is consistent with 

findings of other studies (Anderson 2003). The overall condition on the Forest is still for 

a high beetle infestation. This translates into a short-term favorable habitat condition for 

the black-backed woodpecker (USDA Forest Service 2010). This species’ Forest-wide 

population trend is likely to decline in the future as vegetation management efforts to 

reduce the fire-hazard and insect-risk continue (USDA Forest Service 2010). 

Additionally, SS4C and 5 (habitat needed when no burned or MPB areas are available) 

combined declined in 2009. 

Potential suitable habitat is present in the project area. Late succession stands containing 

large diameter dead trees (snags) created by natural events (wind, lightning), and areas of 

MPB activity are currently present within or adjacent to the Vestal project area. 

Observations have occurred within the project area. 

Brown Creeper (MIS)

The brown creeper is selected as an MIS to evaluate the effects of Forest Plan

implementation and natural change on the ability of the Forest to support species that rely 

on a variety of spruce, late-successional and dense mature pine conditions to meet their 

needs. 

This small forest bird occurs in low abundance throughout the Black Hills and is 

associated with mature and late succession forest (SS4C and 5) conditions and spruce 

forests. The preferred nesting habitat for this species is mature, old growth forest (SS5)

that is undisturbed and contains a closed canopy (Hejl et al. 2002, Wiggins 2005). 

Results from monitoring data identify white spruce and late successional pine as the most 

important habitat type for this species (Panjabi 2001, 2003, 2005). Other important 
Vestal Final Environmental Impact Statement Chapter 3

55

habitat requirements are areas of large trees (i.e., >10” dbh), loose bark, areas infested 

with bark beetles and snags (DeGraaf et al. 1991, Wiggins 2005). Dead or decaying trees 

and snags provide substrate for nests and foraging. Nesting habitat generally contains 

trees that are >9” dbh (Hejl et al. 2002). Evidence also suggests that this species is 

sensitive to the effects of forest fragmentation (Wiggins 2005). It is considered an 

uncommon permanent resident of the Black Hills (Tallman et al. 2002), largely tied to 

late successional pine and white-spruce habitats (Panjabi 2003, 2005). 

In 2009, brown creeper relative densities continued to decline in northern pine habitat, 

rebounded slightly in white spruce habitat and rebounded considerably in southern pine 

and late successional habitat (SS 4C and 5). Blakesly et al. (2008) determined it may 

take 25 years to detect a 3% annual decline for this species in pine-north, late 

successional and white spruce habitats and 30 years in pine-south habitat. However, in 

the short-term, relative densities declined in 2007 compared to previous years, but 

rebounded in 2009 in most habitats sampled (USDA Forest Service 2010). 

Observation data for the brown creeper reveals a short-term downward Forest-wide 

population trend. It appears that Objective 238a is being met, although short-term 

activities to meet the SS 4C objective may be affecting the Forest’s ability to provide 

very large trees in SS 4C. Continued effort and additional time is needed to increase the 

acres of SS 5 (USDA Forest Service 2008, 2009). 

The species was observed in low numbers but scattered throughout the project area in SS

4B and 4C ponderosa pine sites. Currently, there are a total of about 13,000 acres of SS

4B, 4C and 5 ponderosa pine, and 42 acres of white spruce in those same structural 

stages. However, the preferred large diameter trees are only found occasionally. 

Additionally, there are pockets of MPB that have opened up some of these stands. 

Ruffed Grouse (MIS)

The ruffed grouse is selected as a Forest MIS to be an indicator of aspen quantity and 

vigor in pure and mixed stands. It was selected to evaluate the effects of Forest Plan

implementation and natural change on the ability of the Forest to support species that rely 

on a variety of conditions in aspen to meet their needs (USDA Forest Service 2005a). 

Ruffed grouse prefer young to medium -aged aspen stands (Tallman et al. 2002) but have 

been observed in other habitat types in the Black Hills, including open pine forests 

(Panjabi 2001, 2003). Ruffed grouse can survive on a diverse diet in the spring, summer 

and fall (Bolen & Robinson 2003), which may explain the range of habitat types the 

species has been recorded in from RMBO monitoring data (Panjabi 2001, 2003). 

However, ruffed grouse feed on tree buds in the winter and are almost completely 

dependent on aspen for food, shelter and escape cover. Ideal ruffed grouse habitat 

consists of plentiful aspens in all age-classes (i.e., sapling, pole-sized and mature; Bolen 

& Robinson 2003). 

Ruffed grouse are a resident species where found and range from central Alaska to 

northwestern California, Idaho, Utah, Wyoming and Montana. They extend east through 

Minnesota, Ohio and the Appalachian Mountains from Virginia to northeastern Georgia 

(DeGraaf et al. 1991). It is considered an uncommon permanent resident in the Black 

Hills (Tallman et al. 2002) with greatest abundance in the northern Hills (Panjabi 2003). 
Vestal Final Environmental Impact Statement Chapter 3

56

The long-term habitat trend for ruffed grouse is one of decline. Aspen acreage has been 

reduced from the historic condition overall. However, there has been a slight increase in 

aspen acres during the past five years. More time and effort would be needed to increase 

aspen acreage in the future. Implementation of a ruffed grouse monitoring protocol 

should allow for the detection of a long-term population trend (USDA Forest Service 

2010). 

Aspen acreage in the project area currently totals 431 acres. This does not include 

scattered hardwood clones within conifer dominated sites. The hardwood sites represent 

all of the structural stages. This species has been observed within the project area. 

Song Sparrow (MIS) 

This species is an indicator of riparian habitat condition. The song sparrow was selected 

as a Forest MIS to evaluate the effects of Forest Plan implementation and natural change 

on the ability of the Forest to support characteristic riparian species that rely on a variety 

of riparian conditions to meet their needs (USDA Forest Service 2005a).

The song sparrow can be found throughout the Black Hills but is primarily dependent on 

riparian habitat with streamside thickets and willows. Highest densities were recorded in 

montane riparian habitat and to a lesser extent foothill riparian and white spruce habitat 

types. The spruce habitat the species was observed in usually occurred adjacent to 

riparian areas (Panjabi 2003). The latest estimate of riparian habitat on the Forest is 

about 64,000 acres. This includes riparian areas with an overstory of hardwoods or 

conifers. Of this acreage, about 12,000 acres have a shrub (willow) component. No 

Forest-wide data on riparian resource condition was collected in FY 2008 (USDA Forest 

Service 2009). 

Data from the Monitoring the Birds of the Black Hills (MBBH) program show that the 

song sparrow is well-distributed throughout the northern Black Hills and Bearlodge 

Mountains, with a more localized distribution in the central and southern Hills (USDA 

Forest Service 2009). Further monitoring and analysis is required to clarify the 

population trend. Because the quality of riparian habitat has decreased since preEuropean settlement, this would indicate a long-term declining habitat trend. However, 

in the short-term, small riparian habitat enhancement projects that have improved riparian 

conditions in some areas contribute to habitat enhancement and to achievement of 

Objective 238a. More monitoring and habitat restoration projects are warranted for a 

better assessment of the song sparrow trends (USDA Forest Service 2006a).

Song sparrows have been reported within the Vestal project area. Habitat exists along 

most perennial streams and even some ephemeral and intermittent streams.

Mountain Sucker (MIS and R2 Sensitive) 

The mountain sucker was designated as a Management Indicator Species (MIS) to 

evaluate the quality and connectivity of stream habitat on the Black Hills National Forest. 

The mountain sucker is also a R2 sensitive species. The effects to the mountain sucker 

are evaluated in the Biological Evaluation.

The Forest-wide trend for this species is one of decline (USDA Forest Service 2005b, 

2010). The mountain sucker historically occurred in French Creek. The first recorded 

occurrence was in 1893 at Custer, SD (Evermann & Cox 1896). Stream surveys in French 
Vestal Final Environmental Impact Statement Chapter 3

57

Creek in 1960 found mountain suckers downstream of Stockade Lake/Dam (Stewart & 

Thilenius 1964). French Creek upstream of Stockade Lake was not surveyed. Surveys in 

1984 and 1992-93 captured mountain suckers in French Creek downstream of Stockade 

Lake, but not upstream of the lake (Ford 1988, SDGFP 2009). SDGFP fisheries surveys 

in 2009 in streams within the Vestal project area did not collect any mountain suckers. 

Species of Local Concern (SOLC) 

Black Hills Supplement “r2_bh_2600-2011-1” to Forest Service Manual 2600 became 

effective September 6, 2011 and provides direction for the management of SOLC (USDA 

Forest Service 2011). As defined by this supplement, a species of local concern is a 

plant, fish or wildlife species (including subspecies or varieties) that does not meet the 

criteria for sensitive status. These could include species with declining trends in only a 

portion of R2, or those that are important components of diversity in a local area. The 

local area is defined as Forest Service lands within the Black Hills National Forest. This 

supplement also provides a detailed explanation of the evaluation criteria used to select 

species of local concern and a current list for the Black Hills National Forest (USDA 

Forest Service 2011).

Atlantis Fritillary (SOLC) 

The Atlantis fritillary is an endemic butterfly of the Black Hills and is restricted to 

Custer, Lawrence, and Pennington counties. It prefers wet meadows and moist canyons 

(Marrone 2002). Recent surveys indicate species presence appears to be correlated with 

spruce, flowing water and relatively high elevation (Reiser & Spomer 2005). 

Due to the restricted nature of the Atlantis fritillary’s distribution in the Black Hills,

development or management activities within suitable habitats pose a risk to long-term 

persistence. Much of the fritillary’s habitat is privately owned. Surveys conducted in 

2005 throughout the forest identified 20 sites with Atlantis fritillary. Of these 20 sites, 

only three were known to have Atlantis fritillary presence prior to this survey. Although 

the species may be more common than previously thought, it still has a limited range and 

appears tied to permanent montane wetlands in the Black Hills. Habitat consisted of a 

wet area along the riparian corridor with some spruce present (Reiser & Spomer 2005). 

No surveys were conducted within the project area; however, there were observations of 

this species within the project area (French Creek and Tenderfoot). 

Tawny Crescent (SOLC) 

The tawny crescent is found in open meadows, stream bottoms, roads, trails, and riparian 

woodlands (Stefanich 2001). It is also found in mesic forest corridors across an ecotone 

between mixed-grass meadows or prairie grasslands to adjacent woodlands (Royer & 
Vestal Final Environmental Impact Statement Chapter 3

59

Marrone 1992). Elsewhere in the Dakotas, adults are known to forage for nectar from a 

variety of floral species, including dogbane, leafy spurge and various composite flowers. 

Tawny crescent larvae appear dependent on asters as a food source although the specific 

host species and their relationship remain unclear (Stefanich 2001). 

In South Dakota, the tawny crescent is restricted in its distribution to the Black Hills. 

The populations inhabiting the Black Hills of South Dakota and Wyoming are considered 

genetically isolated and disjunct from crescents elsewhere (Royer & Marrone 1992). 

Tawny crescents were observed at two of 20 monitoring sites on the Mystic Ranger 

District in 2002 (USDA Forest Service 2004). However, there continue to be no reliable 

estimates of local abundance or population estimates for the Black Hills (Stefanich 2001). 

Stefanich (2001) hypothesized that the only limiting factor in the Black Hills is the 

destruction of this butterfly’s habitat or isolation of colonies to the extent that populations 

are unable to disperse. This species was observed several times just outside the project 

area. 

Callused Vertigo (SOLC) 

In 2002, the Forest received the final report for a contract to inventory and/or monitor 

357 sites for land snails (Frest & Johannes 2002). Callused vertigo was found sparingly 

in 63 of the 357 sites inventoried/monitored. The sites where callused vertigo was found 

were wet, relatively undisturbed forest, most often closed canopied white spruce or 

ponderosa pine with a varied understory containing relatively diverse floras and deep 

litter, generally on shaded north-facing slopes and often at the slope base or extending 

slightly onto the adjacent floodplain. The most common substrate was limestone, but 

callused vertigo also occurred occasionally on schist-derived soils. Down woody 

material that helps maintain moist soil conditions and lessens sun exposure is an 

important habitat element. Foraging substrate appears to consist of decayed deciduous 

leaves and herbaceous plants. 

Callused vertigo has been found at one site in (Site 112) the project area and sites near 

the area, indicating that the species may be found throughout the Project Area in similar 

habitat (refer to Frest & Johannes 2002 for exact location of that site). The narrowly 

restricted geographical range of the callused vertigo includes South Dakota (51 sites), 

Wyoming (12 sites in the Bear Lodge Mountains), North Dakota, Minnesota, and Alberta 

(Frest & Johannes 2002). The callused vertigo is currently ranked secure globally but 

imperiled in South Dakota (NatureServe 2011). 

The monitoring protocol for snails was not funded in 2005 - 2008 (USDA Forest Service 

2006a, 2007, 2008, 2009); therefore data to assess the status of SOLC snails is not 

available for then. Tronstad and Anderson (2011) modeled potential habitat in the Black 

Hills for these snails, and monitored some of the Frest and Johannes (2002) sites, but 

none were monitored in the project area. Avoidance of known sites is currently the best 

available option for conserving and/or enhancing habitat at known snail colonies. 

Mystery Vertigo (SOLC) 

In 2002, the Forest received the final report for a contract to inventory and/or monitor 

357 sites for land snails (Frest & Johannes 2002). Mystery vertigo was found in 23 of the 

357 sites inventoried/monitored. They were not generally abundant at any site. Mystery 
Vestal Final Environmental Impact Statement Chapter 3

60

vertigo is generally restricted to rich lowland wooded sites, quite often in the white 

spruce community, but occasionally in the ponderosa pine community. The forest 

canopy is generally closed or nearly so, with well-developed litter and a rich understory. 

Sites are usually in leaf litter at the base of a wooded, north-facing slope on limestone or 

schist substrates. Down woody material that helps maintain moist soil conditions and 

lessens sun exposure is an important habitat element. Mystery vertigo was not common 

in taluses but could be found crawling on rock surfaces in moist weather and appears to 

feed on the organic coating of rock surfaces and partially decayed leaves. All sites with 

mystery vertigo were in the central or northern Black Hills or the Bear Lodge Mountains. 

This species was not found within the project area, but it was found relatively close to the 

project area, indicating it could be present. 

The mystery vertigo is rare in the United States and occurs only in South Dakota (21 

sites); Wyoming (2 sites in the Bear Lodge Mountains); Michigan (1 site); Maine (2 

counties); and a few northern Wisconsin, Michigan, and Minnesota sites (Frest & 

Johannes 2002). The species appears to be more common in adjoining areas of southern 

Canada, generally from the Great Lakes eastward. Mystery vertigo is currently ranked 

“apparently secure” globally and critically imperiled in South Dakota (NatureServe 

2011). 

Frigid Ambersnail (SOLC) 

Nekola (2003) considered this species a “duff-specialist.” Duff specialists were strongly 

affected by human activities, suggesting that protecting soil and surface characteristics 

are important in their conservation. In 2002, the Forest received the final report for a 

contract to inventory and/or monitor 357 sites for land snails (Frest & Johannes 2002). 

The frigid ambersnail was found in 12 of the 357 sites inventoried/monitored. The frigid 

ambersnail was rare at all locations, and very few live adults were observed during the 

early 1990s surveys. Live specimens were identified at one site close to the Project Area 

(Site 349), indicating that the species may be found throughout the project area in similar 

habitat (refer to Frest & Johannes 2002 for exact location of this site). Locations are 

widely distributed geographically across the Forest at varying elevations (3,800 to 6,800 

feet). The species was usually found on limestone but also on schist soils, and colonies 

were often found in somewhat dry wooded limestone talus, generally near the slope base. 

They were most often found in rather open ponderosa pine forest, often with a secondary 

deciduous tree and shrub component, although white spruce was a minor component at a 

few sites. According to Frest and Johannes (2002), the family of land mollusks that 

includes the frigid ambersnail is associated not only with rather moist forest sites but also 

with quite dry and open settings in much of the western United States. 

The frigid ambersnail is currently found only in Iowa (14 sites), South Dakota (12 sites), 

and Wisconsin (Frest & Johannes 2002). The frigid ambersnail is currently ranked as 

critically imperiled globally and in South Dakota (NatureServe 2011). 

Striate Disc (SOLC) 

In 2002, the Forest received the final report for a contract to inventory and/or monitor 

357 sites for land snails (Frest & Johannes 2002). The striate disc was found live in only 

18 of the 357 sites inventoried/monitored. Striate disc was most often found in litter in 

rich mesic forest, generally on shaded, north-facing slope bases, often bordering or 
Vestal Final Environmental Impact Statement Chapter 3

61

ranging slightly onto stream floodplains. They were most frequently in white spruce 

communities but also aspen and riparian habitats at the base of slopes where deciduous 

trees and shrubs were often common. Most sites had soils derived from weathered 

limestone, although four sites were on schist substrate. Foraging substrate consists of 

decayed deciduous leaves and herbaceous plants. Down woody material that helps 

maintain moist soil conditions and lessens sun exposure is an important habitat element. 

Sites where the striate disc occurs appear restricted to the higher elevations of the 

limestone plateau of the west-central and north-central portions of the Black Hills. No 

specimens were found within or near the project area.

The range of the striate disc includes Wyoming (2 sites), Montana (1), Colorado (perhaps 

26 sites), South Dakota, Oregon (1), California (2), Utah (5), Arizona (3), and New 

Mexico (7) (Frest & Johannes 2002). NatureServe (2009) also lists 5 records in Montana. 

Live sites have also been reported from several Canadian provinces. The striate disc is 

currently ranked globally as G5 (secure), and S2 (imperiled) in South Dakota 

(NatureServe 2011). 

Sharp-shinned Hawk (SOLC) 

Sharp-shinned hawks nest almost exclusively in conifers, with the exception of some 

densely leafed deciduous trees that also provide nest concealment (Platt 1976, Reynolds 

et al. 1982, Joy 1990). On the Forest, nests occur in white spruce (Stephens & Anderson 

2002) and in pine forest. Sharp-shinned hawks have also recently been detected in 

ponderosa pine, riparian, aspen, and burned habitats on the Forest, but these were not 

observations of nest sites (Panjabi 2001, 2003 and 2005). 

The association between nesting habitat and young seral stage has been noted by several 

authors (Bildstein & Meyer 2000, Bosakowski & Smith 2002, Stephens & Anderson 

2002), but they have been found nesting in mature sites. On the Black Hills National 

Forest, one of the two documented sharp-shinned hawk nests was located in a 42-acre 

stand of white spruce sapling/pole-sized trees. Young stands with mid-to-high canopy 

cover levels for nesting correspond most closely with structural stages 3B (sapling-pole 

stands with 40 percent to 70 percent canopy closure) and 3C (sapling-pole stands with 

greater than 70 percent canopy closure). Canopy closure ranged from 30 to 70 percent, 

but previous studies have tended to find high canopy closure (i.e., ≥68 percent) 

characterizing nesting habitat (Bildstein & Meyer 2000, Bosakowski & Smith 2002). 

Habitat loss or alteration resulting in a loss of suitable nesting habitat as well as a 

decrease in prey abundance and availability are thought to be the most significant threats 

to accipiter species’ persistence (Reynolds 1983, Stephens & Anderson 2002). Habitat 

loss may also occur as forests mature beyond early seral stages. 

The sharp-shinned hawk breeds from Alaska to Newfoundland, south throughout much of 

North America, Mexico, and into Central and South America wherever suitable habitat 

occurs (Stephens & Anderson 2002). The species is considered a partial to long-distance 

migrant, with northern-most individuals wholly abandoning their breeding ranges and 

wintering in the southern United States. Other birds may remain on their breeding ranges 

throughout the winter. In South Dakota, the sharp-shinned hawk is considered 

“uncommon,” with the only recorded occurrences in the western part of the state 

(Peterson 1995). In the Black Hills, they have been observed at all elevations (Peterson 

1995), but estimates of local abundance are not available due to their low numbers 
Vestal Final Environmental Impact Statement Chapter 3

62

(Panjabi 2003). The species has been observed an average of three times per year since 

bird monitoring began in 2001 (Panjabi 2005). In 2011, an active sharp-shinned nest was 

found in site 030905-10 in the project area. Additionally, sharp-shinned hawks have 

been observed within the town of Custer (personal observation). 

Currently, the amount of potential nesting habitat (SS 3B and 3C pine) in the project area 

is 2,565 acres or 10% of the project area.

Cooper’s Hawk (SOLC) 

The Cooper’s hawk has been observed in a variety of habitats in the Black Hills, 

including ponderosa pine, white spruce, riparian, shrublands, and burned areas (Panjabi 

2001, 2003 and 2005; Peterson 1995). The species appears to be widespread but 

uncommon on the Forest. Bird monitoring over the past three years has yielded an 

average of about five sightings per year (Giroir et al. 2007). 

The Cooper’s hawk is considered a habitat generalist but typically requires wooded areas 

for nesting. The most common forest type in the Black Hills, ponderosa pine, is used for 

nesting in other areas of the species range (Stephens & Anderson 2002). The bird is 

known to nest in riparian, conifer, and aspen forests (Stephens & Anderson 2002). 

Stephens and Anderson (2002) analyzed the likely habitat preferences of the Cooper’s 

hawk on the Forest based on information from nearby regions. Range-wide, most pairs 

nest in patches of mature forest with moderate-to-high (i.e., 60 to 90 percent) canopy 

closure near openings (Stephens & Anderson 2002). Nest tree diameters are usually 

larger than what is randomly available. The Cooper’s hawk forages opportunistically 

across a diversity of habitats and preys on a variety of mid-sized birds and mammals 

(Stephens & Anderson 2002). 

In ponderosa pine, SS 4B (mature stands with 40 to 70 percent canopy closure) and SS 

4C (mature stands with >70 percent canopy closure) correspond most closely to the 

nesting habitat preferences of the Cooper’s hawk. The Cooper’s hawk often nests near, 

and hunts, along forest edges and clearings. Riparian-woodland communities also 

provide potentially important habitat for the Cooper’s hawk. 

The Cooper’s hawk breeds throughout the United States, southern Canada, and northern 

Mexico. Some birds may remain on their breeding ranges throughout the winter. In 

South Dakota, the Cooper’s hawk is considered “uncommon,” with the only recorded 

occurrences in the western part of the state (Peterson 1995). In Wyoming, it is regarded 

as a “common summer resident” (Luce et al. 1999). 

Active Cooper’s hawk nests (2) were discovered within the project area. 

Broad-winged Hawk (SOLC) 

The broad-winged hawk is one of eastern North America’s most common woodland 

hawks. It is generally associated with dry to wet deciduous, mixed, or occasionally 

coniferous forests (Johnsgard 1990). Broad-winged hawks forage in mature to oldgrowth forests, along forest streams, roads, and openings (Stephens & Anderson 2003). 

In the Black Hills, the broad-winged hawk nests primarily in ponderosa pine in mixed 

pine and deciduous habitats, occasionally with a white spruce component (Powder River 

Eagle Studies 2000). Although considered rare in both Wyoming (Luce et al. 1999) and 
Vestal Final Environmental Impact Statement Chapter 3

63

South Dakota (Peterson 1995), the species was the second most frequently encountered 

raptor during surveys in 1996 and 1997 (Powder River Eagle Studies 2000). Of 27 

broad-winged hawk nests found on the Forest, 25 were in ponderosa pine while one was 

in an aspen and one was in a paper birch. Nest trees had an average dbh of about 16 

inches; canopy closure in nest stands averaged 66% with a range of 45 to 96% (Stephens 

& Anderson 2003). These nest-stand characteristics equate to SS 4B, 4C and 5. Nest 

sites typically were in areas with slopes <10%. No association between nest sites and 

forest openings or wetlands was detected on the Forest (Stephens & Anderson 2003). 

There were 24 broad-winged hawks identified along transects in 2004, mainly in the 

northern Black Hills and Bear Lodge mountains. Fourteen of these were located in 

aspen, eight in late-successional pine and two in the Jasper Burn Area (Panjabi 2005). 

Nineteen were detected in 2005. Only two were detected in 2009 (USDA Forest Service 

2010), and in 2010, a nesting pair were found within Norbeck Wildlife Preserve (personal 

observation). The species was not observed in the Project Area during field 

reconnaissance.

The broad-winged hawk breeds from Nova Scotia to central Alberta, south to Texas, and 

east to the Atlantic coast (Johnsgard 1990). These hawks are complete migrants, best 

known for their migratory congregations of thousands of individuals as they head south 

into Central and South America (Johnsgard 1990, Stephens & Anderson 2003). 

Northern Saw-whet Owl (SOLC) 

The northern saw-whet owl is a habitat generalist found at lower to middle elevations in 

forested habitat, particularly in riparian areas. The highest densities of this species tend 

to be found in coniferous forests (Cannings 1993). This species nests in cavities in snags

excavated by flickers (Collaptes auratus) and other large woodpeckers. Nests tend to be 

in mature forest, while dense, sapling-pole-sized stands are preferred for roosting 

(Johnson & Anderson 2003). Saw-whet owls also utilize dense riparian woodlands for 

roosting. This species often forages along forest edges, preying on small mammals 

(Cannings 1993). 

Structural stages 4C and 5 most closely resemble the preferred breeding and nesting 

habitat for the saw-whet owl. These structural stages contain mature and old growth 

forest with at least 70% canopy cover in SS 4C. Snags are an integral part of nesting 

habitat. Snags do not occur evenly across the landscape. There would likely be some 

areas with higher snag densities that will allow the species to persist. Large trees are also 

important for this species because they provide future large snags, if not killed by MPB. 

Saw-whet owls occur from the southern boundary of Alaska, across most of Canada and 

into the northern tier of states from Maine to Minnesota (Johnson & Anderson 2003). 

The Rocky Mountains, the Cascade Range, Coastal Range and the Sierra Nevada 

Mountains all support year-round populations. In the Black Hills, seasonal migration is 

likely among high- and low-elevation habitat (Johnson & Anderson 2003). In South 

Dakota, the northern saw-whet owl is considered an uncommon resident (Tallman et al. 

2002). The saw-whet owl was determined to be widely distributed and common in the 

Black Hills (Fauna West Wildlife Consultants 2003, Drilling 2010). The northern sawwhet owl is tracked by the South Dakota Natural Heritage Program (SDNHP) as a rare 

species and is ranked three on a rarity scale of one to five, with one being critically 
Vestal Final Environmental Impact Statement Chapter 3

64

imperiled and five being secure (SDNHP 2007). This species has been observed within 

the project area.

Pygmy Nuthatch (SOLC) 

The pygmy nuthatch is a primary cavity nester that also uses secondary cavities 

(Ghalambor 2003, Kingery & Ghalambor 2001) found in mature yellow-pine 

communities throughout the West (Ghalambor 2003). Pygmy nuthatches prefer old or 

mature undisturbed forests, but are also known to use open, park-like stands of ponderosa 

pine (Kingery & Ghalambor 2001). This presents a challenge in the Black Hills where 

ponderosa pines typically grow very densely in the absence of disturbance. Roosting 

habitat for the pygmy nuthatch varies seasonally. Foraging habitat is primarily in pine 

stands with high canopy closure (Ghalambor 2003). Pygmy nuthatches likely need 

heterogeneous forests with a mixture of well-spaced old trees and trees of intermediate 

age (Kingery & Ghalambor 2001). 

The preference for undisturbed forests may relate to the availability of large snags. The 

nuthatch is a weak cavity excavator, requiring soft, large snags for nesting and communal 

winter roost sites (USDA Forest Service 1996, Appendix H). Dead or decaying 

coniferous trees and snags provide substrate for nest cavities. Nesting habitat generally 

includes trees that average 15 to 27 inches in diameter (Ghalambor 2003, Kingery & 

Ghalambor 2001). Suggested practices include managing for at least three to five snags 

(19 inches in diameter) per acre (Kingery & Ghalambor 2001). 

Structural stages 4C and 5 most closely resemble one component of preferred habitat (old 

or mature undisturbed forest). Structural stage 4A most closely resembles open, parklike, mature forest conditions. Phase II structural stage objectives are designed to 

manage for the various structural stages across the landscape in a diversity of sizes and 

shapes. Snags that are greater than 15 inches in diameter are an integral part of pygmy 

nuthatch nesting and roosting habitat. Snags do not occur evenly across the landscape. 

There would likely be some areas with higher snag densities that would allow the species 

to persist. Large trees are also important for this species because they provide foraging 

habitat, and because they are source for future large snags used for roosting and nesting. 

The pygmy nuthatch subspecies of the Black Hills (Sitta pygmaea melanotis) is found 

from southern interior British Columbia and south throughout the forests of the Rocky 

Mountain West into Mexico and western Texas (DeGraaf et al. 1991). It is considered an 

uncommon resident in both Wyoming (Luce et al. 1999) and South Dakota (Peterson 

1995). There are no reliable estimates of pygmy nuthatch abundance for the Black Hills 

(Ghalambor 2003). 

On the Black Hills, as elsewhere, identified limiting factors are thought to be the 

availability of snags for nesting sites and winter roosting habitat and the availability of 

productive foraging habitat (Ghalambor 2003). Estimates of local abundance are 

unavailable due to the scarcity of this species and its unpredictable distribution (Panjabi 

2003). Three pygmy nuthatches were recorded by RMBO in 2009 (USDA Forest Service 

2010). Pygmy nuthatches have been observed within the project area.

Northern Long-eared Myotis (SOLC) 

At the western edge of its range, the northern myotis is found in the wooded riparian zone 

in badlands and prairies to higher elevation coniferous and deciduous woodlands 

(Schmidt 2003a). In the Black Hills region, this species has been captured at elevations 

ranging from 4,000 to 6,500 feet (Schmidt 2003a). Luce et al. (1999) listed habitat 

associations as dense ponderosa pine and mixed coniferous/deciduous forest. 

Hibernacula include caves and mines. Individuals tend to wedge into crevices and are 

not easily detected or counted (Schmidt 2003a). During the summer, non-reproductive 

bats roost singly or in small groups of fewer than 10 individuals. Day roosts of males and 

non-reproductive females have been reported in buildings; under shingles; behind 

shutters of buildings; underneath exfoliating tree bark; inside cavities or crevices of trees; 

and in caves, mines, and quarries (Schmidt 2003a). Maternity roosts have been reported 

in buildings, under loose bark, and in crevices and cavities of deciduous trees and 

ponderosa pines. Northern myotis have been documented using ponderosa pine snags as 

summer/maternity roosts in the Black Hills (Cryan et al. 2001) and in other regions (Rabe 

et al. 1998). Rabe et al. (1998) summarize some key snag characteristics for the northern 

myotis and four other Myotis species in Arizona; roost snags were generally larger in 

diameter, had more loose bark, and were found at higher densities. Cryan et al. (2001) 

reported the average snag size for roosts in the Black Hills was about 15.6 inches. 

Maternity roosts are typically small and comprise 5 to 65 individuals (Schmidt 2003a). A 

single offspring is born in late July (Higgins et al. 2000). 

Foraging areas may include hillsides, ridge tops, and riparian woodlands (Luce et at.

1999, Schmidt 2003a). The availability of suitable hibernacula, maternity roosting sites, 

and foraging areas all represent potential risk factors for this species (Schmidt 2003a). 

The northern myotis ranges across most of eastern North America, extending from 

central Quebec, Ontario, and the southern half of Manitoba, south through all of the 

Dakotas, eastern Nebraska, Kansas, and Oklahoma, and then east to the Atlantic coast. 

Turner (1974) reported northern myotis from Pennington and Custer counties in South 

Dakota and Weston County in Wyoming. The South Dakota Natural Heritage Program 

reported records of this species from Meade, Lawrence, Jackson, and Harding counties as 

well. Luce et al. (1999) reported records of northern myotis from latitude 7 and longitude 

21, which includes Crook and Weston Counties, Wyoming and one historical record from 

the western part of the state. 

Suitable roosting habitat exists within the project area. 

Small-footed Myotis (SOLC) 

The small-footed myotis is found in a variety of habitats ranging from arid desert and 

badland habitats to riparian zones and grasslands. It is usually associated with rocky 

areas like bluffs, dissected breaks, ridges, cliffs, and major rock outcroppings within 

these habitats. In the Black Hills region, this species has been captured at elevations 

ranging from 3,800 to 6,000 feet (Schmidt 2003b). 

Hibernacula for this species include mines and caves. Relatively warmer areas of caves 

with the least climatic fluctuations seem to be the preferred microsite. Mine hibernacula 

are also documented (Turner 1974). Maternity and summer roosts are usually associated 
Vestal Final Environmental Impact Statement Chapter 3

66

with rock features (e.g., bluffs, ridges, cliffs, boulders, and major outcroppings) within a 

variety of habitats (Schmidt 2003b). The small-footed myotis is one of the few bat 

species that actually roosts in cavities at ground level. Day roosts include buildings, 

behind the bark of pine trees, in rock crevices, under rocks on the ground, in holes in 

banks and hillsides, and in abandoned swallow nests. The availability of suitable 

hibernacula, maternity roosting sites, and foraging areas all represent potential risk 

factors for this species (Schmidt 2003b). 

The small-footed myotis ranges across most of western North America, extending from 

central British Columbia, southern Alberta and southwestern Saskatchewan, south to the 

central States of Mexico (Schmidt 2003b). It has been reported from all five South 

Dakota counties of the Black Hills (Turner 1974). Luce et al. (1999) reported records 

from latitude 7, and longitude 21 and 28 in Wyoming, which is most of the area 

bordering South Dakota with the possible exception of Weston County. However, Turner 

(1974) reported seven records from Weston County, Wyoming and recorded this species 

as widespread but not abundant in the Black Hills. 

Suitable roosting habitat exists within the project area.

Long-eared Myotis (SOLC) 

The only records of long-eared myotis in the Black Hills come from unpublished reports 

(Schmidt 2003c). It is unknown whether the Black Hills supports a self-sustaining 

population (Schmidt 2003c). This species is associated with coniferous montane habitats 

and has been reported foraging among trees and over woodland ponds (Schmidt 2003c). 

Limited data suggest that the long-eared myotis uses ponderosa pine snags as summer 

and maternity roosts in other regions (Rabe et al. 1998, Vonhof & Barclay 1997). Rabe 

et al. (1998) summarize some key snag characteristics for the long-eared myotis and four 

other bat species in Arizona: roost snags were generally in larger dbh, had more loose 

bark, and were found at higher densities. Stumps, also of large diameter, have been 

documented as summer roost sites for the long-eared myotis in British Columbia (Vonhof 

& Barclay 1997). 

Although relatively little is known about this bat’s specific hibernation needs, hibernation 

sites include caves and mines (Higgins et al. 2000), but there are no known reports of 

them hibernating in the Black Hills (Schmidt 2003c). Reproductive females have been 

found in buildings, rock crevices, and hollow trees. Reported day roosts for this species 

include buildings (often abandoned), under loose tree bark, in hollow trees, among 

timbers of an unused railroad trestle, in caves and mines, in cliff fissures, and in portable 

latrines (Schmidt 2003c). This bat often uses caves and mine tunnels as nightly roosts 

(Higgins et al. 2000, Schmidt 2003c). 

The long-eared myotis ranges across much of montane western North America, extending 

from central British Columbia; the southern half of Alberta and the southwestern corner 

of Saskatchewan; south to Baja California along the Pacific coast; along the western

edges of the Dakotas; and most of Wyoming and Colorado to northwestern New Mexico 

and northeastern Arizona (Schmidt 2003c). 

Suitable roosting habitat exists within the project area.

Long-legged Myotis (SOLC) 

The long-legged myotis is primarily associated with montane forest. In the Black Hills, 

this species occurs primarily at elevations between 4,500 and 6,500 feet (Turner 1974). 

This species has been documented using ponderosa pine snags as summer/maternity 

roosts in the Black Hills (Cryan et al. 2001) and in other regions (Rabe et al. 1998). 

Cryan et al. (2001) found the long-legged myotis roosting in rock crevices in the Black 

Hills where they may be subject to disturbance by rock climbing activities. Snags used 

for roosting in the Black Hills were larger in diameter, in a greater state of decay, and 

were in higher densities when compared to random snags (Cryan et al. 2001). Roosts 

were generally on south-facing slopes within late-successional pine forests. Day roosts 

are usually under the bark of ponderosa pine and in snags. These bats prefer dead snags 

characterized by reduced needles and twigs, loose bark, broken tops, hard-to-spongy 

heartwood, and spongy-to-soft sapwood. Roost snags are generally taller than 

surrounding trees, close to other available trees, and surrounded by a relatively open 

canopy. Reproductive females have been found roosting in buildings, rock crevices, 

under the bark of trees, and in hollow trees (Schmidt 2003d). Hibernating individuals are 

known to use caves in the Black Hills, including Bush’s and Jewel Caves (Schmidt 

2003d, Luce et al. 1999, Turner 1974). 

The long-legged myotis forages over meadows, ponds, streams, and open mesic habitats 

of the Black Hills where it feeds on flying insects, particularly moths (Luce et al. 1999, 

Turner 1974). Although this species is the most common and widely distributed bat in 

the Black Hills (Turner 1974), general limits to persistence include availability of roost 

sites, hibernacula, and foraging areas. The reported preference of this bat for roosting in 

snags suggests that the availability of mature forests with abundant snags may be a 

limiting factor (Schmidt 2003d).

The long-legged myotis is common across the western United States. Its range extends 

across most of western North America, from southeastern Alaska through the western 

and southern half of British Columbia and the southern half of Alberta, down the western 

edge of the Great Plains states and into central Mexico (Schmidt 2003d). This species is 

considered the most common and widely distributed member of the genus Myotis in the 

Black Hills region and has been reported from all counties occupied by the Black Hills in 

both South Dakota and Wyoming (Schmidt 2003d, Luce et al. 1999, Clark & Stromberg 

1987, Turner 1974). Suitable roosting habitat occurs within the project area.

Northern Flying Squirrel (SOLC) 

Throughout their range, northern flying squirrels inhabit a wide variety of woodland 

habitats, typically dominated by conifers or mixed coniferous/deciduous forests (WellsGosling & Heaney 1984). Recent studies have indicated northern flying squirrels occupy 

a variety of forest types and are not necessarily old growth dependent (Cotton & Parker 

2000). Turner (1974) noted that the highest densities are likely found in white-spruce 

forests in moist canyons of the northern Black Hills. In the Black Hills National Forest, 

northern flying squirrels are associated with cavities in live, quaking aspen and paper 

birch trees and aspen, birch and ponderosa pine snags, as well as nests in large, live 

ponderosa pine and white spruce trees (Hough 2009). Duckwitz (2001) found flying 

squirrels in Wind Cave National Park in ponderosa pine types that had an open canopy 

allowing understory grasses to prosper. Open pine types may provide the “openness” 
Vestal Final Environmental Impact Statement Chapter 3

68

necessary for gliding. Locations where flying squirrels were found in Wind Cave 

National Park did have large pines. Stands of dense doghair pine were avoided (Duckwitz 

2001). 

Hough (2009) found that ponderosa pine is the most important foraging habitat in the 

Black Hills. Flying squirrels selected areas with larger trees and more canopy cover. 

Structural stages 1, 2 and 3B were avoided, SS 3C and 4B were selected for, and SS 3A, 

4A and 4C were used in proportion to availability. Aspen and birch were avoided for 

foraging because flying squirrels are associated with mixed conifer-hardwood forests, 

feeding primarily on truffles associated with conifers; however, aspen and birch are 

important for den sites (Hough 2009). Grass and shrub areas do not provide good 

foraging habitat due to the lack of fungus growth and seed production (Hough 2009). 

Structural stages 3A, 3C, 4A, 4B, 4C and 5 all provide suitable habitat on the Forest. 

Standing snags and downed logs are also habitat components. Northern flying squirrels 

typically nest in tree cavities or abandoned woodpeckers holes in winter and summer. 

They may also build nests of twigs, bark, and roots and use abandoned bird nest 

platforms in summer (Wells-Gosling & Heaney 1984). 

Although flying squirrels are thought to prefer mesic, mature, spruce forests in the Black 

Hills, mature and late-successional stage pine forests (SS 4C and 5) on more mesic sites 

may also contain the snag resource northern flying squirrels appear to require. The 

Forest is conserving habitat for the northern flying squirrel in regards to spruce habitat, 

but progress towards increasing the acres of structural stage 5 and the very large tree 

component in Management Areas 5.4 and 5.43 is still needed to enhance habitat (USDA 

Forest Service 2010). 

This nocturnal mammal is a resident of the mountainous areas of the western United 

States and boreal forests of North America. The northern flying squirrel in the Black 

Hills is an isolated population with the nearest population located in the forests of 

western Wyoming (Clark & Stromberg 1987, Wells-Gosling & Heaney 1984). 

Meadow Jumping Mouse (SOLC) 

This species is strongly associated with riparian habitats along small streams in meadows 

and habitats beneath forests with an understory of deciduous shrubs, grasses, forbs and 

fallen logs; it is presumed to disperse primarily along stream corridors (Luce et al. 1999). 

The meadow jumping mouse is a profound and continuous hibernator, retreating to 

burrows in dry ground from October to May. Burrows are also used for nests (Luce et al. 

1999). 

Domestic animal overgrazing, which consistently removes dense vegetation along eastern 

creeks in Wyoming, is thought to have contributed to this species’ scarcity (WYNDD 

2002). However, there is little evidence that the mouse is scarce relative to historic 

abundance. Zapus in general tend to occur at relatively low abundance and it is uncertain 

whether the current abundance is different than the past. Limits to abundance and 

distribution include reduction of understory shrubs, grasses and forbs in low-to-mid 

elevation riparian areas (Luce et al. 1999, WYNDD 2002). Fragmentation of appropriate 

riparian habitat may limit this species’ ability to disperse.

Meadow jumping mice range across Alaska through Canada, the northern and eastern 

United States, and across the Great Plains to the eastern foothills of the Rocky Mountains 
Vestal Final Environmental Impact Statement Chapter 3

69

(WYNDD 2002, Whitaker 1972). The Bear Lodge meadow jumping mouse (Zapus 

hudsonius campestris) is a separate subspecies that occurs in the Black Hills region 

(Beauvais 2001) and is listed as rare in Wyoming (Luce et al. 1999). There are seven 

recorded occurrences of this species on the Bearlodge Mountains of the Black Hills, 

including the type specimen collected in 1864 (WYNDD 2002). Turner (1974) collected 

a total of 207 specimens from across the Black Hills and Bear Lodge Mountains in South 

Dakota and Wyoming. He collected the species as far south as Wind Cave National Park 

and characterized it as common throughout the study area (Black Hills and Bear Lodge 

Mountains). Cryan and Ellison (2005) found the species still occurs throughout the Black 

Hills area. An observation of this species occurred within the Vestal project area along 

Upper French Creek. 

Mountain Goat (SOLC) 

This species inhabits rugged terrain including cliffs, rock faces, ledges, and talus slopes, 

typically above timberline. The mountain goat is found most abundantly on rock 

outcrops and high elevation meadows. The range of the mountain goat extends from the 

northern United States Rocky Mountains to southeast Alaska (Clark & Stromberg 1987). 

Mountain goats are characteristically found in sub-alpine and alpine tundra areas in the 

Northern Rockies and coastal mountain ranges of western North America (Higgins et al. 

2000). Foraging habitat is alpine meadow, grassland, and montane shrubland (Benzon & 

Rice 1987). Recommendations for improving habitat for the species consist of thinning 

dense stands of ponderosa pine, maintaining meadows and placing clear-cuts next to or 

interspersed between granite outcroppings (Ted Benzon, Big Game Biologist, SDGFP, 

Division of Wildlife, personal communication). 

Mountain goats feed throughout the morning, rest at midday, and resume feeding in the 

late afternoon, continuing into the evening. A wide range of forage is utilized including 

chokecherry, Russian buffaloberry, grasses and sedges, quaking aspen, serviceberry, wild 

rose, willow, and hazel (Richardson 1971). Usually the most available forage rather than 

the most palatable forage is consumed (Richardson 1971). 

Primary range and habitat of the mountain goat in the Black Hills covers about 2,000 

acres and is centered around Harney Peak and the Needles (Richardson 1971). Mountain 

goat populations appear to be trending downward from an estimated population of 168 

animals in 2002 (USDA Forest Service 2004) to 80 animals in 2009 (Huxoll 2010). 

However, in 2010, population increased little to 90 animals (Huxoll 2011). The cause of 

the mountain goat population decline is unknown. Possible causes include high predator 

(mountain lion) numbers, genetics (all descendants from a small number of goats in 

1924), and/or loss of or lack of habitat. The Forest will continue to coordinate with the 

South Dakota Department of Game, Fish and Parks to determine if more specific habitat 

management actions are needed to conserve/enhance habitat for this species (USDA 

Forest Service 2010). Since 2007, no hunting licenses have been issued for this species. 

The Black Hills mountain goat population occurs largely within the Black Elk Wilderness 

(MA 1.1A), somewhat in the Norbeck Wildlife Preserve (MA 5.4A), Buckhorn Mountain 

(MA 4.1) where patch clearcuts have been created to provide for forage, and within 

Crazy Horse boundary.

Threatened and Endangered Species

A list of federally threatened, endangered and proposed species has been provided by the 

U.S. Fish and Wildlife Service (USFWS), South Dakota State Office, and last verified on 

September 1, 2011 (USFWS 2011a). The USFWS lists the following endangered and/or 

threatened species for Custer County, South Dakota: whooping crane, sprague’s pipit, 

and black-footed ferret. 

The whooping crane and least tern have been removed from the list of species considered 

on the Black Hills National Forest under Section 7 consultation (letter of concurrence 

from D. Gober, Field Supervisor, USFWS, Pierre, South Dakota, dated August 8, 2003). 

It was determined that management activities on the Forest would have ‘no effect’ on

these species because the Black Hills National Forest lacks suitable habitat.

The U.S. Fish and Wildlife Service reviewed the conservation status of Sprague’s Pipit to 

determine whether the species warrants protection under the Endangered Species Act. 

The status review found that listing Sprague’s Pipit as threatened or endangered is 

warranted, but that listing the species at this time is precluded by the need to complete 

other listing actions of a higher priority. To ensure this review was comprehensive, the 

Service solicited information from state and federal natural resource agencies and all 

interested parties regarding the Sprague’s pipit and its habitat.

Refer to Appendix G which contains a summary of the BA/BE completed for this project. 

Region 2 (R2) Sensitive Species

The current sensitive species list for the Rocky Mountain Region (R2) was renewed on 

June 10, 2011. Sensitive species for the Black Hills National Forest are listed on the R2 

threatened, endangered, and sensitive species home webpage (USDA Forest Service 

2011). 

The pre-field review of R2 Sensitive Species was completed using survey results, district 

records, literature reviews, on-line databases, and the South Dakota Natural Heritage 

Database. There are fourteen R2 sensitive species which occur or could potentially occur 

(habitat may be present) in the Vestal project area. 

Species Presence Confirmed & Habitat Present:

• Bald eagle

• Northern goshawk

• Black-backed woodpecker 

• Northern leopard frog 

• Black Hills redbelly snake

• Fringed myotis

• Townsend’s big-eared bat

• Black-tailed prairie dog

• Mountain sucker 

Species Presence Expected and Habitat Present:

• Hoary bat

• American marten
Vestal Final Environmental Impact Statement Chapter 3

71

• Flammulated owl

• Cooper’s mountain snail 

• Regal fritillary butterfly

These sensitive species were analyzed in the Vestal Wildlife BA/BE due to the species 

presence and/or presence of potential habitat in the project area. Two of the species 

listed, the black-backed woodpecker and mountain sucker, are also designated as MIS

species. 

Bald Eagle (R2 Sensitive Species) 

Bald Eagles have been documented in all counties in the Black Hills. In South Dakota, 

approximately 300 bald eagles winter in the Black Hills and along the Missouri River 

(USFWS 2011d). This species population is a rare breeder in South Dakota, although the 

nesting population is slowly expanding (South Dakota Game, Fish and Parks [SDGFP] 

2011a). South Dakota trends based on mid-winter surveys are reported by the SDGFP 

(2011b). One eagle successfully fledged in 2008 (USDA Forest Service 2010) and again 

in 2011 (Patti Lynch, 2011, BHNF, Mystic RD, personal communication). 

Bald eagles may roost near Bismarck Lake. This species has been observed within the 

project area. 

Northern Goshawk (R2 Sensitive Species) 

In the Black Hills, this species is usually found in ponderosa pine, especially in more 

closed canopy with multiple vegetation structure. Goshawks typically nest in relatively 

dense (dependent on forest type) forest areas and use a mosaic of structural stages for 

foraging within their home range (Kennedy 2003). 

In the Black Hills, this species is considered a rare permanent resident and has been 

found nesting in all the counties in the Black Hills (Tallman et al. 2002). 

There are two known goshawk territories that are monitored within the project area. 

Each has been active within five years. There is potential over-wintering habitat in the 

Vestal project area. Goshawk surveys were conducted June-July of 2006 through 2011 

within the area. In 2011, only one goshawk territory was active; however, sightings of 

goshawks have occurred within the project area. 

Black-backed Woodpecker (R2 Sensitive Species, MIS) 

This species existing condition is discussed under MIS, earlier in this document. 

Northern Leopard Frog (R2 Sensitive Species) 

This species requires three types of habitat. Winter habitat, usually lakes, streams or 

ponds, is needed for winter torpor. High oxygen saturation is best in the winter waters. 

Summer habitat for this insectivorous frog is considered upland forage ground often near 

the breeding ponds. The third habitat is breeding/tadpole habitat. This is usually shallow 

bodies of water with little to no current, aquatic vegetation, good water quality, and little 

overhead canopy. Warmth from the sun is needed for proper development of the 

tadpoles. Larval development becomes an issue if water is too cold. This could explain 

why frogs are not breeding at springs in the Black Hills (Smith & Keinath 2007). 
Vestal Final Environmental Impact Statement Chapter 3

72

In the Black Hills, this species’ current distribution is considered high where suitable 

habitat is available (USDA Forest Service 2004). This species is vulnerable to habitat 

alteration/loss, introduced predaceous fish, susceptible to overgrazing, low water quality 

and wetland loss (Smith & Keinath 2007). 

Suitable habitat exists in the Vestal project area. This species has been observed along 

streams and at one pond. 

Black Hills Redbelly Snake (R2 Sensitive Species)

The Black Hills subspecies is an isolated population; the next nearest population is 

located in the eastern part of South Dakota, some 300 miles away. Suitable habitat may 

be broadly distributed or abundant in the Black Hills. The snake is not rare in good 

habitat and is considered quite common in the Black Hills (USDA Forest Service 2000, 

SDGFP 2011c). The biggest threat appears to be removal of large, downed woody 

material and logging in wet areas. Predation, wildfire and road use can impact this 

species. 

Suitable habitat exists in the Vestal project area. Observations have occurred within the 

project area.

Fringed Myotis (R2 Sensitive Species)

This subspecies only occurs in the Black Hills and possibly northwest Nebraska. This 

species is considered a rare to uncommon year-round resident. Known locations are 

found in Lawrence, Meade, Pennington and Custer Counties of South Dakota and 

possibly Crook and Weston Counties in Wyoming (Luce et al. 1997, Tigner & Stukel 

2003). Factors that affect this species are human disturbance of roosting and hibernation 

sites, low reproductive rate and habitat loss. Disturbance by humans, especially in 

hibernacula and maternity roosts, can be a threat to survival of these animals (Keinath 

2004). 

No known caves that serve as bat hibernacula were identified in the project area; 

however, there are abandoned mine sites (Ventling) adjacent to and within the project 

area where this species has been detected hibernating (B. Phillips, District Wildlife 

Biologist, Black Hills National Forest, 2011). This site most likely serves as a day/night 

roost site for this species. The entire project area contains many rock outcrops, as well as 

snags and large trees that may be used as roost sites for many species of bats. There are 

other mine sites in and around the Project Area that could have potential bat habitat. 

Townsend’s Big-eared Bat (R2 Sensitive Species)

Within the Black Hills, the species has been recorded in Fall River, Meade, Pennington, 

Custer and Lawrence counties (Higgins et al. 2000). Population trends appear to be 

declining in the Black Hills as well as throughout their range. Loss of habitat is the main 

contributor to lower numbers, which is attributed to the loss of large caves and 

dilapidation of mines. These bats are extremely sensitive to disturbances in the vicinity 

of their roosts, including loud noises such as those produced by motorized off-road 

vehicles, discharging of firearms, and other such activities (Gruver & Keinath 2006). 

There are abandoned mine sites within and around the Project Area. There are also manmade structures, rock outcrops, and cliff-face crevices and fissures. This species was 
Vestal Final Environmental Impact Statement Chapter 3

73

detected hibernating at the Ventling mine. This site most likely serves as a day/night 

roost site for this species. Other abandoned mine sites within or around the project area

most likely also provide hibernation and roosting habitat. 

Black-tailed Prairie Dog (R2 Sensitive Species) 

Suitable prairie dog habitat on the Black Hills National Forest is limited to non-rocky 

grassland soils on the Hell Canyon RD. In 2005, there were approximately 400 acres of 

prairie dog towns on the Forest consisting of about 10 active colonies (USDA Forest 

Service 2009). The colonies are comparatively small and disjunct from adjacent known 

colonies. Prairie dog towns on the Forest have remained stable or have increased despite 

recreational shooting and disease. All of the prairie dog towns occur within grazing 

allotments (District records). Black-tailed prairie dogs are found to be more abundant in 

heavily grazed areas than in un-grazed areas in the Black Hills of southwestern South 

Dakota. 

In South Dakota the black-tailed prairie dog’s range includes most all western counties 

(Higgins et al. 2000). 

There is an active, small prairie dog town (031303-36; Glen Erin) in the project area. 

This area was mapped in 2011, and is 9.3 acres. 

Mountain Sucker (R2 Sensitive Species, MIS)

The mountain sucker occurs most often in cool, clear mountain streams with moderate 

water velocities. Stream substrate associated with mountain sucker habitat varies widely 

and ranges from mud to sand, gravel and boulders, although cobbles are most common. 

This species is found on the stream bottom and is closely associated with cover (exposed 

roots, undercut banks, log jams and boulders). Mountain suckers are benthic feeders and 

their diet is primarily simple plants like diatoms and green algae, but small invertebrates 

are also ingested. Spawning occurs in the spring, but the exact timing varies by elevation 

and water temperature. In the Black Hills, the spawning period for mountain suckers is 

probably June and maybe early July (Shearer personal communication, 2006). This 

species is an open substrate spawner (broadcast spawner), meaning it does not build or 

defend a nest or redd. The incubation period of mountain sucker embryos is thought to be 

short, around 8 to 14 days (Belica & Nibbelink 2006). 

The status of the mountain sucker in the Rocky Mountain Region and the Black Hills was 

assessed by Belica and Nibbelink (2006) and Isaak et al. (2003), respectively. Mountain 

suckers are native to the Black Hills and comprise the eastern-most range of the species. 

Recent surveys suggest mountain suckers occur in many of its historic drainages 

throughout the Black Hills (Isaak et al. 2003), but localized population reductions or 

absence at selected sites has occurred (USDA Forest Service 2010).

The mountain sucker historically occurred in French Creek. The first recorded occurrence 

was in 1893 at Custer, SD (Evermann & Cox 1896). Stream surveys in French Creek in 

1960 found mountain suckers downstream of Stockade Lake/Dam (Stewart & Thilenius 

1964). French Creek upstream of Stockade Lake was not surveyed. Surveys in 1984 and 

1992-93 captured mountain suckers in French Creek downstream of Stockade Lake, but 

not upstream of the lake (Ford 1988, SDGFP 2009). SDGFP fisheries surveys in 2009 in 

streams within the Vestal project area did not collect any mountain suckers. 
Vestal Final Environmental Impact Statement Chapter 3

74

Hoary Bat (R2 Sensitive Species)

The hoary bat is a solitary species, roosting primarily among foliage in deciduous and 

coniferous trees, often along the edges of clearings. They have been observed in 

numerous forested cover types, including mixed conifer, lodgepole pine, ponderosa pine, 

pinyon-juniper, and riparian areas with cottonwood and willow. Hoary bats forage on a 

wide variety of insects, especially moths (Shump & Shump 1982, Valdez & Cryan 2009). 

They are long-distance, seasonal migrants (Cryan et al. 2004). 

Because hoary bats are not known to use caves or abandoned mines or go into a 

prolonged hibernation, they are not thought to be vulnerable to the disease referred to as 

‘white-nose syndrome’ (WNS), as are some cave hibernating bat species.

In South Dakota this species is considered state-wide in distribution (Higgins et al. 2000), 

and the hoary bat is known to occur throughout the Black Hills region. 

Data on hoary bat population trends are scarce; however, even in the absence of these 

data, there is evidence that this species is experiencing a downward population trend. 

The bark beetle epidemic in R2 has killed more than 3 million acres of pine forests, 

decreasing the quality and quantity of this vital roosting habitat. 

This species is new to the R2 Sensitive Species list as of June 10, 2011. Therefore, this 

species has not been tracked in the project area, or there are no known 

observations/recordings of this species. However, it is expected that suitable habitat is 

present within the project area. 

American Marten (R2 Sensitive Species) 

Recent research on the Black Hills National Forest indicates that high quality marten 

habitat consists of mature spruce stands with canopy cover >50% near riparian areas at 

elevations >5,200 feet (Fecske et al. 2002). However, spruce stands that are too small, 

have little canopy cover and/or located long distances from water provide little suitable 

habitat (Fecske & Jenks 2002). Ponderosa pine is not considered optimum habitat, 

although there is evidence that martens use pine habitat in the Black Hills.

According to a recent marten study (Fecske 2003), the greatest marten concentrations 

appear to be in the northern part of the Forest southwest of Deadwood, SD (northern 

subpopulation) and in and around the Norbeck Wildlife Preserve (Norbeck 

subpopulation), (Fecske 2003). These two dominant subpopulations are likely very 

important in maintaining species persistence in the Black Hills. The Black Hills supports 

an isolated population, with the nearest neighboring population in the Bighorn Mountains 

of Wyoming (Buskirk 2002). 

Track-plate boxes for detection of marten were set up in Vestal in the Tenderfoot area. 

No marten were detected or observed at the track-plate boxes or within project area. 

However, a small amount of suitable habitat does exist.

Flammulated Owl (R2 Sensitive Species)

There have been two reports of flammulated owls in the past 10 years that could be valid 

sightings. These could represent periodic use by transient individuals, or the beginning 

of a range expansion. In 2002 at least two and maybe three flammulated owls were 

observed in the northern Black Hills (Panjabi 2003). 
Vestal Final Environmental Impact Statement Chapter 3

75

Migration in this species is still poorly understood but recent review of the data suggests 

that this species may be a long distance, north-south, migrant. Experiments have found 

that this owl does not become torpid in cold temperatures. It is likely that prey 

availability also plays a large role in the migratory behavior of this species (McCallum 

1994). 

There are no records for this species in the project area, but based on published 

information, and Black Hills sightings, it is reasonable to expect that suitable habitat for 

flammulated owls is currently present in the Vestal project area. The ponderosa pine 

structural stages corresponding most closely to potential flammulated owl nesting and 

foraging habitat on the Forest are SS 4A, 4B, and 5 (USDA Forest Service 2005a). 

Cooper’s Mountain Snail (R2 Sensitive Species)

In the Black Hills, the Cooper’s mountain snail is mostly found in the higher elevations 

of the Limestone Plateau, along limestone outcrops, talus, and isolated exposed 

limestone. Sites range from open to closed canopy coniferous overstory to mixedconiferous to deciduous tree overstory with well developed litter layer (Anderson 2005). 

Dead and down woody debris is important characteristic at the micro-site level. Risk 

factors for the Cooper’s mountain snail are loss of moist habitat conditions through 

drought, fire, vegetation management, trampling, overgrazing, development, road 

construction, and habitat fragmentation. 

Distribution data for the United States and Canadian provinces is known to be 

incomplete. Current identified distribution is in the Black Hills of South Dakota and 

Wyoming. Populations are limited in the Black Hills to suitable habitat mostly in 

Spearfish Creek, upper reaches of Rapid Creek, Higgins Gulch, Prospect Gulch and 

Grand Canyon near Deadwood, SD. This species could also be found in other drainages 

in the northwest region of the Black Hills. According to Frest and Johannes (2002), 

others cited a wider range. 

There are two Frest snail survey sites that occur within the project area: 030906-9 (#112) 

and 030904-8 (#67). This species was not found at either site (refer to Frest & Johannes 

2002 for details on site location, species found and habitat). Snail surveys were 

conducted during summers, but no snails were found. 

Regal Fritillary Butterfly (R2 Sensitive Species)

Suitable habitat is limited to larger native meadows in the Black Hills where native 

violets exist (Royer & Marrone 1992, Marrone 2002). 

Historically, this species ranged from New England to the Great Plains. The Black Hills 

is at the western edge of this species’ range. Distribution within the Black Hills may be 

related to moisture gradient (USDA Forest Service 2000). Threats to the species include: 

overgrazing, herbicide/pesticide use, fire, cultivation of prairie, loss of meadows to trees, 

and invasion of non-native plants (Royer & Marrone 1992, USDA Forest Service 2000). 

The regal fritillary has not been documented within the Vestal project area. Potential

suitable habitat occurs in wet meadows and riparian areas. 
Vestal Final Environmental Impact Statement Chapter 3

76

Demand Species

Demand species are important local game animals which are not included in other 

emphasis groups above. The Rocky Mountain elk (Cercus elaphus nelson) and 

Merriam’s wild turkey (Meleagris gallapavo merriami) are demand species which occur 

in the project area. 

Rocky Mountain Elk (Demand Species) 

Elk use a wide variety of vegetation types on the Forest but show a preference for 

forested riparian areas, forested stringers in meadows, and deciduous stands of birch or 

aspen (SAIC 2003). Elk find cover (thermal, hiding or both) on the Forest in the denser 

stands (SS 3C, 4C and 5) of conifers (summer and winter) and hardwoods (summer only). 

For forage, however, they rely on more open stands and meadows and prairies, all of 

which may provide an abundance of grasses, forbs, and/or shrubs (SAIC 2003). The 

summer range typically provides a mixture of open brushy and grassy areas, water 

sources, and areas of dense forest cover. During winter, most elk move to winter ranges. 

Some mature bulls stay on summer ranges where the snow depths can reach 4 feet. The 

fall diet is primarily grasses, forbs and some browse. In winter the diet shifts to mostly 

browse and some grasses (Higgins et al. 2000). 

The elk population of the Black Hills is difficult to estimate in part because of interstate 

movements of the species. However, the 2007 estimate placed the population level at 

3,800 elk in the South Dakota Black Hills (Huxoll 2008). The 2010 estimate decreased 

to 3,100 elk (Huxoll 2011). No population estimates are available for the Wyoming 

portion of the Black Hills. The Forest has committed (through Objective 217) to 

managing habitat for a total of 4,350 elk, which was the combined population objective 

established by the two state game agencies in 1996 (USDA Forest Service 2005a). 

Elk are sometimes seen in the Vestal project area. The project area is within MA 5.1 

(resource production emphasis), which includes management for a diversity of wildlife 

species, and MA 5.4 (Big Game Winter Range Emphasis), which is managed to provide 

high-quality winter and transitional habitat for deer and elk, along with other wildlife 

needs. The Rocky Mountain Elk Foundation (2002) considers part of the project area as 

crucial annual range for elk and part of the area as summer range and winter range (small 

portion). 

Hiding cover is important during the fall hunting season (SAIC 2003). Roads negatively 

affect elk because roads degrade habitat and contribute to animal displacement and stress. 

Elk selected against grassland habitat and for dense (i.e., >70 percent canopy cover) 

conifer stands during the big game hunting season (i.e., 1 September to 30 November) in 

the Black Hills (Rumble et al. 2005). Additionally, Rumble et al. (2005) found that elk 

generally avoid areas within 1 km of primary and secondary roads during this time 

period. Currently, open road density within the project area is 1.5 mi/mi2

 (this includes 

Forest System roads and County roads). Management Area 5.4 contains 5 mi/mi2 of 

roads, FSR and County roads. However, during seasonal closures from December 15 – 

May 15, annually, open road density is 2.2 mi/mi2. 
Vestal Final Environmental Impact Statement Chapter 3

77

Merriam’s Wild Turkey (Demand Species) 

The wild turkey is a non-migratory species. Merriam’s turkeys use many of the 

vegetation types occurring on the Forest. Open areas (structural stages 1, 2, 3A, 4A) are 

important for foraging during the summer, though meadows are seldom selected for 

(Rumble & Anderson 1996). Dense mature ponderosa pine (structural stages 4C and 5) 

serves as winter cover and a source of mast (Rumble and Anderson 1996). Roost sites 

are typically on top of slopes or ridges in trees >9” dbh with layered horizontal branches 

(Rumble 1992). Winter diets consist mainly of ponderosa pine seeds and summer diets 

are of grass seed and foliage (Rumble and Anderson 1996). In the southern Black Hills, 

successful nest sites were located in pine stands with 41-70 percent canopy cover on 

steep slopes, cliff faces and in areas with greater visual obstruction, vegetation height and 

shrub cover (Lehman 2005). Primary nest predators consist of coyotes (Canis latrans), 

ravens (Corvus corax), magpies (Pica pica), and American crows (Corvus 

brachyrhynchos) (Rumble et al. 2003). 

The Merriam’s turkey is common and widespread on the Forest, with an estimated 

population of 35,000 birds in 2008 in the South Dakota portion of the Black Hills (Huxoll 

2009), which has increased to 38,000 in 2010 (Huxoll 2011). The species occurs in a 

wide variety of vegetation types, including foothill and montane riparian associations, 

pine-juniper shrubland, mixed grass prairie, and ponderosa pine, white spruce, and aspen 

forest stands (Panjabi 2003). Turkeys are common in and around the project area.

Migratory Birds

Many species of migratory birds are of international concern due to naturally small 

ranges, loss of habitat, observed population declines and other factors. Species of 

concern applicable to project-level conservation are identified by many sources, 

including the Endangered Species Act, the Regional Forester’s sensitive species list, the 

Black Hills National Forest MIS and Species of Local Concern list, internal and public 

scoping efforts, and the USFWS Birds of Conservation Concern (BCC) (USFWS 2008). 

BCC 2008 publication partitions North America into 37 Bird Conservation Regions 

(BCRs, Fig. I). The Black Hills is included in BCR 17 – Badlands and Prairies, and this 

table has changed since the existing condition report was written. Of the 28 bird species 

found in BCR 17, 15 are duplicated on the Regional Forester’s sensitive species list, and 

are evaluated in the BA/BE if they have potential to occur in the Black Hills. Six species

are not expected to occur in the Black Hills due to lack of habitat. There are 7 remaining 

species that could potentially occur in the Black Hills: golden eagle, prairie falcon, 

upland sandpiper, black-billed cuckoo, red-headed woodpecker, pinyon jay, and 

dickcissel. Of these seven species, only the golden eagle has the potential to occur within 

the project area. The prairie falcon, upland sandpiper, black-billed cuckoo, red-headed 

woodpecker, pinyon jay, and dickcissel will not be analyzed because suitable habitat is 

not present in the Vestal project area.

Golden Eagle (Migratory Bird)

The golden eagle is typically found in open country from desert grasslands to above 

timberline. It usually avoids densely forested areas. Typical habitat is grass-shrub, 

shrub-sapling and/or open coniferous forests (Johnsgard 1990). This species prefers large 

trees and cliffs for nesting, roosting and perching. Additionally, cliffs overlooking 
Vestal Final Environmental Impact Statement Chapter 3

78

grasslands serve as typical nest sites. They may use the same nest or alternate nests 

between years (DeGraaf et al. 1991). Golden eagles hunt by soaring-searching and using 

perch sites to identify prey (Johnsgard 1990). Typical food items include: marmots 

(Marmota flaviventris), prairie dogs (Cynomys ludovicianus), ground squirrels 

(Spermophilus spp.), weasels (Mustela spp.), lagomorphs (Sylvilagus and Lepus spp.), 

rattlesnakes (Crotalus viridis), and most medium-sized birds (DeGraaf et al. 1991). 

Golden eagles breed from western Alaska east through Canada, south to Baja California, 

northern Mexico, west-central Texas, western Oklahoma, Nebraska and the Dakotas. 

The species winters from south-central Alaska, southern Canada and throughout the 

western breeding range (Johnsgard 1990). They are considered uncommon permanent 

residents in western South Dakota (Tallman et al. 2002) and only ten have been detected 

during recent bird monitoring efforts (Giroir et al. 2007). Golden eagles were observed 

in the project area during 2008 surveys. Golden eagles are commonly seen feeding on 

carrion along roads in the Black Hills during winter. 

Environmental Consequences

Snags and Down Woody Material

Alternative 1

The No Action alternative would provide the greatest opportunity for increased snag 

numbers, in the short-term (approximately 15-20 years) and down woody material. This 

alternative allows forested stands that are denser and more mature to become more 

stressed and vulnerable to MPB attack and wildfire – variables that can significantly 

increase snag densities and downed wood in an area. Mountain pine beetle activity in the 

project area is increasing, and infestations are spreading across the project area, with 

most tree mortality currently occurring in the northern part of the project area. It is 

expected that snag densities would increase as a result of MPB caused mortality in the 

area. However, these snags are expected to break or fall in about 5 years, contributing to 

an excess of downed woody material. Species that utilize snags and the provided habitat 

will benefit with this snag increase in the short-term. 

Alternative 2 

This Alternative is expected to increase snags and down woody material in the project 

area, but not as much as Alternative 1 does in the short-term. Design criteria is included 

with this alternative to protect existing snags. No snags would be cut unless they are 

deemed a safety hazard during operations, consistent with Standard 2301. 

Vegetation treatments, both commercial and non-commercial, have the potential to 

reduce snags and downed wood. Proposed fuel treatments including mechanical 

thinning, prescribed burning and deadfall treatment, also have the potential to reduce 

snags and downed wood. Snags created by fire may stand longer than those created by 

insect attacks. 

This alternative also proposes sanitation treatment on all pine stands within the project 

area. Sanitation removes trees which are infested with MPB and which would provide 

short-term snag habitat, if left on site. However, MPB are expected to create a large 
Vestal Final Environmental Impact Statement Chapter 3

79

number of snags, which generally break and fall within five years. Down woody material 

would subsequently increase throughout the project area, as these trees fall. 

This alternative increases opportunities for future large snags in this area. The proposed 

treatments are expected to retain more mature, live trees on the landscape which may 

become future snags, because it would reduce potential MPB caused mortality. Because 

snag densities are currently increasing, and snags would be retained, unless a safety 

hazard, this alternative would meet or even exceed, in the short-term, Forest Plan

Objectives 211 and 212. 

Cumulative Effects 

Past firewood cutting, timber harvest, wildfires and fuels management activities have 

contributed to the loss of snag and downed wood habitat. Fire, insects and other causes 

of tree mortality continue to create snag/downed wood habitat. Mountain pine beetle 

activity and potential wildfires would likely increase snags, although MPB-killed trees 

may only remain on the landscape for five years. Conversely, the current fuelwood 

cutting policy which allows snags to be removed within 300 feet of many roads in the 

project area, may cause a decrease in snag numbers, although it would most likely be 

negligible.

Summary of Effects on MIS

The following is a summary of effects to wildlife MIS. A detailed analysis can be found 

in both the Wildlife and Fisheries Specialist Reports in the project record. 

Table 36. Summary of Effects on MIS 

Summary of Effects on MIS

Alternative 1

No Action

Alternative 2

Proposed Action

Beaver

(Caster canandensis)

Direct and Indirect Effects

No direct effects. Habitat would 

remain intact due to riparian

protection at Bismarck Lake. Pine 

may continue to encroach into 

riparian habitat. If current MPB 

activity continues, pine would die 

and hardwoods may increase, 

resulting in increased, quality 

habitat and food sources for beaver. 

No direct effects are expected. Treatments 

would result in an expected increase in 

hardwoods, which would benefit beaver 

habitat. Treatments are expected to increase 

the amount of hardwoods along riparian 

corridors. Long term effects could result in 

improved habitat/food sources and possible 

population increase.

Cumulative Effects

Would not have adverse cumulative 

effects. 

Would not have adverse cumulative effects.

Summary

Neither alternative would negatively impact beaver habitat at Bismarck Lake. 

Proposed harvest and post-harvest treatments that would benefit hardwoods may be 

beneficial for beaver. Treatment activities would meet Forest Plan Objective 238a. 

Population viability for this species was evaluated during the Phase II Amendment 

to the 1997 Black Hills National Forest Land and Resource Management Plan 

(USDA Forest Service 2005a). The Forest Plan Phase II Amendment determined 

that population viability across the Planning Area would be maintained for this

Summary of Effects on MIS

species if pertinent Forest standards and guidelines are followed. The proposed 

action would meet these standards and guidelines. Therefore, this species is likely to 

persist on the Forest. Under both alternatives, there would be adequate habitat for 

maintaining populations for beaver. 

Alternative 1

No Action

Alternative 2

Proposed Action

White-tailed Deer

(Odocoileus 

virginianus)

Direct and Indirect Effects

In time pine seedlings may provide 

additional hiding cover along some

roads. If existing MPB activity 

continues foraging habitat would be 

expected to increase significantly, 

however thermal cover would 

decrease. Screening/hiding cover 

would remain adequate.

Fawning cover would be expected 

to increase as a result of increased 

downed material (eg. logs, shrubs, 

forest floor debris) from MPB killed 

trees. Potential for shrubs and 

hardwoods to increase, but the 

presence of livestock would 

increase forage competition with 

big game. 

No change to existing open road 

density would occur.

Short term disturbance and displacement 

expected from vegetation treatments. 

Screening cover may be reduced along some 

roads, however much of the screening cover 

is due to topography rather than vegetation. 

Design criteria are included to retain at least 

20% screening cover along all arterial and 

collector roads, resulting in Guideline 3203

being met. 

Hiding/thermal cover would be expected to 

decrease from existing condition due to MPB 

activity. However, proposed activities are 

expected to retain more hiding/thermal cover 

than the No Action. 

Open road density would remain similar to 

No Action. Total road miles would be 

increased by one mile; however this road 

would remain closed to the public.

Foraging habitat would be expected to 

increase as a result of proposed activities and 

expected MPB activities. Shrubs, hardwoods 

and meadows may improve habitat enough 

that deer population may increase in number 

within the project area, but may move 

outside of the project area to seek denser pine 

stands. 

Cumulative Effects

Adverse cumulative effects may 

occur. Forage is expected to 

increase, but MPB activities may 

decrease hiding and thermal cover. 

Activities from recreational use and 

private land management would 

also reduce habitat.

Would add to positive effects of past 

prescribed burns and timber harvests by 

increasing diversity of forage, and increasing 

early successional vegetative stages. May 

slightly reduce screening cover, and would 

greatly reduce thermal cover. Potential to 

decrease winter habitat for big game species. 

Expected to add to disturbance by OHV and 

recreation use. Activities from recreational 

use and private land management would also 

reduce habitat.

Summary

Screening cover would be provided at levels noted in Guideline 3203 on all arterial 

and collector roads within the project area. Monitoring data suggests habitat is not 

limiting population growth of deer and the Forest is meeting Objective 238a. 

Neither of the alternatives would contribute to a Forest-wide loss of summer habitat,

therefore, the alternatives would contribute to attainment of Objective 238a. 

However, because of the current MPB infestation along with treatment, the proposed 

action is expected to lessen cover habitat, which is important during hunting season 

and winter for deer and other big game. Adequate habitat across the Forest would

Summary of Effects on MIS

allow for the attainment of Forest Plan Objective 217 (USDA Forest Service 2005a 

and 2006a). Population viability for this species was evaluated during the Phase II 

Amendment to the 1997 Black Hills National Forest Land and Resource 

Management Plan (USDA Forest Service 2005a). The Forest Plan Phase II 

Amendment determined that population viability across the Planning Area would be 

maintained for this species if pertinent Forest standards and guidelines are followed. 

The proposed action would meet these standards and guidelines. Therefore, this 

species is likely to persist on the Forest.

Alternative 1

No Action

Alternative 2

Proposed Action

Golden-crowned 

kinglet 

(Regulus satrapa)

Direct and Indirect Effects

Existing spruce would remain. 

Mountain pine beetle activity is 

expected to continue throughout the 

project area, which may result in an 

increase in spruce. 

No direct effects are expected from project 

activities. No project activities are proposed 

in spruce habitat; some sanitation may occur. 

Vegetation treatments adjacent to spruce 

sites or skid trails running through spruce 

may temporarily disturb/displace individuals. 

Cumulative Effects

No adverse cumulative effects 

expected. No adverse cumulative effects expected.

Summary

The potential habitat available in the project area is on a small scale when compared 

to Forest-wide potential habitat. This would mean that the Forest-wide habitat trend, 

population trend and Objective 238c would not be influenced by the Vestal 

proposed action. As a result, golden-crowned kinglets are likely to persist on the 

Forest. Adequate habitat across the Forest would maintain a viable population of 

golden-crowned kinglets (USDA Forest Service 2005a, p. lll-263).

Population viability for this species was evaluated during the Phase II Amendment 

to the 1997 Black Hills National Forest Land and Resource Management Plan 

(USDA Forest Service 2005a). The Forest Plan Phase II Amendment determined 

that population viability across the Planning Area would be maintained for this 

species if pertinent Forest standards and guidelines are followed. The proposed 

action would meet these standards and guidelines. Therefore, this species is likely to 

persist on the Forest.

Alternative 1

No Action

Alternative 2

Proposed Action

Black-backed 

Woodpecker

(Picoides articus) 

Note: Also R2 

Sensitive Species

Direct and Indirect Effects

Expected MPB activity would 

provide for an increase in habitat in 

the short-term. The risk of standreplacing fire would remain very 

high. Wildfire would provide more 

habitat in the short-term. This 

alternative would provide the 

greatest potential for increase in 

woodpecker habitat, short-term. 

However, it would also result in the 

greatest decrease in dense habitat 

types that are used when no burned 

or MPB habitat is available. It 

would be expected that structural 

stages would transition to earlier 

successional stands (SS1, 2, 3A)

In the short-term, habitat would be provided 

as MPB caused mortality continues in the 

project area. However, actions to reduce 

MPB risk are expected to result in less 

mortality than Alternative 1, No Action. The 

potential for large-scale fire is reduced in this 

alternative. 

This alternative is expected to retain more 

mature, dense stands (SS4B, 4C and 5) and 

more SS4A, which would become future 

dense stands more quickly than the No 

Action alternative. Treatments would be 

expected to retain more large trees for future 

snags versus the No Action alternative. 

Short-term impacts include: abundance of 

snags, potential for accidental loss of 
Vestal Final Environmental Impact Statement Chapter 3

82

Summary of Effects on MIS

Snags would increase and be 

abundant due to natural mortality. 

 

snags/cavities by proposed fuel or harvest 

treatments, prescribed burning may destroy 

some snags and may create some snags, 

disturbance of nesting woodpeckers if 

harvest occurs during nesting season. This 

alternative has the greatest potential to create 

snags for the long-term. 

Cumulative Effects

Past wildfires and past and existing 

MPB infestations have created 

habitat throughout the Forest and 

project area. 

Continued MPB activity throughout the 

forest and project area would continue to 

provide habitat for this species. Fuel (fire) 

management treatments would reduce habitat 

potential for this species. 

Privately owned lands within and adjacent to 

the project area may also provide suitable 

habitat for the black-backed woodpecker. 

Fire-hazard and MPB reduction activities are 

likely to increase on some of these lands in 

effort to prevent loss from wildfire. Cutting 

of snags for fuelwood may reduce the 

number of snags. This could result in a loss 

of habitat, but the amount of area within 

these private lands is relatively small 

compared to what is on the forest (USDA 

Forest Service 2008). The indirect effects 

mentioned above would be an incremental 

impact additional to those on private lands. 

Summary

Alternative 1 has the greatest potential for increasing woodpecker habitat. 

Alternative 2 may decrease preferred and/or potential habitat, but would not affect 

the habitat or population trend Forest wide because of providing for Objective 211

(snags). Snags are not allowed to be cut unless deemed a safety hazard or within 

designated firewood cutting areas. The project area is only a small portion of the 

currently available habitat, new habitat acres are currently being created across the 

Forest. Both alternatives ‘may adversely impact individuals, but not likely to 

result in a loss of viability in the Planning Area, nor cause a trend toward 

federal listing’.

Habitat conditions would be provided, consistent with Objective 238b. The 

proposed action alternatives would meet Forest Plan standards and guidelines; 

therefore this species is likely to persist on the Forest. 

Alternative 1

No Action

Alternative 2

Proposed Action

Brown Creeper

(Certhia Americana) 

Direct and Indirect Effects

Spruce habitat would remain at 42 

acres. Mountain pine beetle caused 

mortality would substantially reduce 

preferred habitat in pine (SS 4B, 4C 

and 5) throughout the project area. 

This change in habitat is expected to 

impact the brown creeper by causing 

displacement of individuals to more 

suitable habitat, which may be 

outside of the project area. In 

addition, the high fire hazard is a 

Timber harvest and prescribed burning may 

destroy nests. Vegetation treatments may 

temporarily disturb individuals. Expected 

MPB activity may reduce habitat resulting 

in displacement of individuals to more 

suitable habitat. 

Risk of MPB infestation would be reduced. 

More preferred habitat would remain than in 

Alternative 1, as pine SS 4B, 4C and 5.

alternative is expected to increase the 

risk of habitat fragmentation and loss

species.

the long-term. 

Fire hazard is also substantially reduced, 

increasing the potential for retention of 

preferred habitat. 

Cumulative Effects

MPB activity would decrease habitat. 

Additionally, vegetation treatments 

on private land may also reduce 

habitat for this species. Habitat 

fragmentation is expected.

Would add to preferred habitat reduction 

within the project area, however with lack 

of treatment habitat may be lost to fire or 

MPB. Additionally, vegetation treatments 

on private land may also reduce habitat for 

this species. Habitat fragmentation is 

expected.

Summary

Both alternatives retain 42 acres of preferred spruce habitat. However, Alternative 2 

would retain more mature and late successional stands and therefore, results in the 

most potential for preferred habitat for the brown creeper. Both action alternatives 

would reduce SS4B from the existing condition; however treatment would reduce 

MPB risk and fire hazard. Habitat would be maintained and the project meets 

Objective 238a. 

The proposed action would meet Forest Plan standards and guidelines; therefore this 

species is likely to persist on the Forest. 

Alternative 1

No Action

Alternative 2

Proposed Action

Ruffed Grouse

(Bonasa umbellus) 

Direct and Indirect Effects

Existing 431 aspen acres would be 

expected to remain. Habitat may 

improve due to expected MPB 

activity resulting in an increase in 

hardwoods due to pine mortality. 

Fallen dead trees may provide 

increased cover. 

Potential for individual mortality from 

vegetation treatments. Short-term 

displacement, but individuals are expected 

to return after implementation. 

Hardwood treatments would increase and 

enhance habitat, with potential to increase 

population. Other vegetation treatments 

would benefit habitat by removing pine. 

Fallen or hinged trees may provide an 

increase in cover for this species and for 

suckering hardwoods. Prescribed burning 

could cause mortality in aspen, negatively 

affecting habitat; conversely, it may 

stimulate aspen regeneration, positively 

affecting habitat. Mountain pine beetle 

caused mortality in pine stands could 

benefit this species by opening up hardwood 

stands and slowing down pine 

encroachment. 

Cumulative Effects

Would not have adverse cumulative 

effects. 

Would help offset negative impacts from 

past activities. Future hardwood treatments 

would continue to improve habitat. 

Summary

Because of proposed hardwood release and hardwood conversion treatments, the 

proposed action is expected to be more beneficial to ruffed grouse than the No 

Action alternative. However, because of MPB activity killing pine, hardwoods may

Summary of Effects on MIS

increase in both alternatives. 

This project is contributing to Objective 238a because the proposed action increases 

the amount of habitat available for ruffed grouse. The proposed action would meet 

all standards and guidelines. Therefore, this species is likely to persist on the Forest. 

Alternative 1

No Action

Alternative 2

Proposed Action

Song sparrow

(Melospiza 

melodia)

Direct and Indirect Effects

Ponderosa pine may continue to 

become denser and encroach into 

hardwood stands and shrubs. 

However, the predicted MPB

effects to conifers would result in 

an increase in hardwoods and 

shrubs, providing improved habitat 

along riparian corridors for this 

species. This alternative would be 

expected to benefit the song 

sparrow.

Direct effects are possible, but it is expected 

that individuals would leave the area before 

that occurs. Vegetation treatments may 

disturb individuals temporarily, but song 

sparrows are expected to return to the area.

Proposed treatments would increase and 

enhance habitat. Some meadows and aspen 

stands near or adjacent to riparian areas 

would be released from pine encroachment. 

Mountain pine beetle caused mortality may 

also benefit this species by killing overstory 

pine along riparian areas. 

Because of vegetation treatments and MPB

activity, hardwoods would increase. 

Additionally, pine habitat would become 

more open causing the potential for shrubs to 

increase in the understory. The additional 

habitat may increase enough for a population 

increase of song sparrow. 

Cumulative Effects

Adverse cumulative effects may 

occur because of livestock grazing.

Adverse cumulative effects may occur 

because of livestock grazing. Project 

activities are expected to outweigh effects.

Summary

The proposed action is expected to have more beneficial impacts to song sparrows 

because of treatments within meadows and hardwood stands that may include 

riparian habitat. Additionally, because of MPB activity, both alternatives have the 

potential for an increase in hardwoods and shrubs.

This project is contributing to Objective 238a because all alternatives increase the 

amount of habitat available for song sparrows. The proposed action would meet 

these standards and guidelines. Therefore, this species is likely to persist on the 

Forest.

Direct and Indirect Effects

the seasonal in-water work restriction to 

avoid the mountain sucker spawning, 

incubation and emergence period. Indirect 

effects to aquatic/riparian habitat are 

predicted to be negligible.

Summary of Effects on MIS

Lake. This may have short-term adverse 

effects resulting from some streambank 

disturbance and additional sediment input 

into the stream. The use of vegetative buffers 

to trap sediment and other techniques that 

minimize ground disturbance, protect 

streambank stability and maintain overhead 

tree canopy to shade streams would mitigate 

adverse impacts to fisheries habitat.

Cumulative Effects

Past, present and reasonably foreseeable actions, such as recreational fishing, nonnative fish stocking, livestock grazing, road use/maintenance and water 

impoundment would continue to directly or indirectly affect fish populations and/or 

their habitat. Existing instream structures that are barriers to fish passage, such as 

dams and “perched” culverts, would continue to fragment the stream network and 

affect fish distribution. These conditions and activities may have either a positive or 

negative effect depending on the fishery resource (native vs. non-native fish) or the 

type of activity (habitat restoration vs. degradation) being considered. Most of these 

effects are long-term because of their chronic, ongoing nature though their 

magnitude and intensity may vary over time.

Summary

This project would have a neutral effect on the Forest-wide population trend of the 

mountain sucker because of the minimal amount of occupied habitat (lower French 

Creek) in the project area and the minor degree of adverse effects to that habitat. The 

implementation of resource conservation measures would meet the intent of Forest 

Plan Objective 238d to maintain stream quality and connectivity. Mountain sucker 

viability is not at risk due to the minor amount of aquatic habitat affected and the 

low magnitude of potential direct and indirect adverse effects anticipated under the 

proposed action. 

The implementation of Forest Plan standards and guidelines (Standards 1106, 1109, 

1113, 1201, 1203 and Guidelines 1115 and 3212), regional watershed conservation 

practices and project-specific design criteria would avoid and minimize long-term 

negative indirect effects to fisheries consistent with Forest Plan Objectives 103, 217 

and 219. Potential adverse effects to aquatic habitat and control nonpoint surface 

water pollution are mitigated consistent with Objective 221 of the Forest Plan. The proposed action ‘may adversely impact individuals, but not likely to result 

in a loss of viability in the Planning Area, nor cause a trend toward federal 

listing’. The No Action alternative may adversely impact individuals as well, 

primarily due to the negative interaction from ongoing non-native fish management 

to provide for recreational fishing opportunities.

any mechanical treatments, spruce, 

hardwoods and open, grassy areas may 

increase because of MPB killing encroaching 

conifers. This increase may improve habitat 

enough to provide the opportunity for a 

population increase. 

Noxious weed treatments would positively 

impact these species by aiding in native plant 

restoration, however there is potential to 

harm the species by treating nectar or larval 

host plants. Rx burning & vegetative 

treatments have potential for direct mortality 

to individuals; however positive impacts 

would be created through pine encroachment 

by opening up meadows/grasslands. 

Cumulative Effects

Would not have adverse cumulative 

effects. MPB activity could 

contribute to enhanced butterfly 

habitat. 

Would have beneficial cumulative effects. 

Improvement of current habitat conditions 

would offset negative effects from livestock 

grazing. Would benefit species due to 

habitat enhancement from past grazing and 

timber harvest. 

Summary

Both alternatives would improve habitat for these butterflies. Alternative 2 would 

result in a greater benefit by further enhancing habitat, in particular by removing 

encroaching pine from hardwoods and meadows, which may be adjacent to riparian 

areas. 

The proposed action would meet these objectives, standards and guidelines. The 

proposed action alternative would contribute toward meeting Forest Objective 221. 

Both species are likely to persist on the Forest. 

Alternative 1

No Action

Alternative 2

Proposed Action

Callused Vertigo

(Vertigo arthuri)

Mystery Veritgo

(Vertigo paradoxa)

Frigid Ambersnail

(Catinella gelida)

Striate Disc 

(Discus shimekii)

Direct and Indirect Effects

Existing forested stands would be 

expected to become denser as fire 

suppression continues. However, 

because of the current MPB

epidemic, dense pine stands (SS 3B, 

3C, 4B, 4C, and 5) are expected to 

decrease from existing condition. 

Canopy would decrease as well as 

moisture levels for these snail 

species. MPB risk and wildfire risk 

would remain or increase. Conifer

encroachment would continue in

hardwood stands, decreasing 

deciduous litter. Conversely, 

hardwoods may increase with MPB

activity, which would increase 

deciduous litter.

The proposed action would allow for more 

riparian and hardwood enhancement and may 

provide better habitat conditions for these 

snail species through post-harvest activities. 

An overall decrease in stand replacing 

wildfires is expected with this alternative. 

This alternative retains more acres of dense 

habitat and increases hardwood acres through 

treatment. Therefore more habitat for the 

callused vertigo, mystery vertigo and striate 

disc snail species would be provided.

Rx burning and vegetation treatments would 

have potential to cause direct mortality to 

individual snails & potential to impact 

habitat, negatively. However, opening up 

forested sites would create more potential 

habitat for the frigid ambersnail. These same 

treatments may decrease available habitat for 

the callused vertigo, mystery vertigo and 

striate disc snails. MPB & wildfire risk 
Vestal Final Environmental Impact Statement Chapter 3

would be reduced. 

Cumulative Effects

Would not have adverse cumulative 

effects. 

The trend of forest succession and fire 

suppression has decreased available water to 

riparian and mesic hardwood habitat and thus 

negatively impacted snail habitat. The recent 

precipitation (past 3 years) may improve this 

situation. Past and current removal of pine 

has had beneficial impacts to water yield, 

hardwood and riparian habitat. Activities 

such as harvest and prescribed fire may have 

also negatively impacted snail habitat 

through eliminating the overstory resulting in 

drying out of wet sites used by snails. These 

impacts are site-specific. Timber sales and 

fuels reduction projects have contributed 

cumulatively to both the beneficial and 

negative impacts to snails. Past activities 

have reduced the area of dense conifer stands 

while fire suppression has allowed natural 

succession to occur which has developed 

dense stands. 

Past and current off-road motorized traffic 

has negatively impacted some snail habitat 

(primarily in riparian areas) through 

removing plants and cover and compacting 

soil. Motorized traffic can also cause 

mortality to snails directly. 

Livestock grazing and recreational use both 

have potential for negative impacts to snails 

and their habitat. These activities would be 

expected to continue within the project area. 

Summary

The proposed action is expected to increase hardwood acres through hardwood 

conversion and release treatments and retains more SS 4A. Therefore, all snail 

species’ habitat would benefit from this alternative. However, this alternative also 

has the potential to cause the most impact to the snail species and their habitat due to 

vegetative treatment as well as prescribed burning. 

The proposed action alternatives would meet Forest Plan standards and guidelines. 

Therefore the alternatives would contribute toward meeting Objective 221. These 

species are likely to persist on the Forest. 

The proposed action would maintain more dense forest conditions than No Action 

due to MPB caused mortality. Both action alternatives would create a more open 

pine forest condition. These actions would have potential for both positive and 

negative impacts on individual snails and habitat. The frigid ambersnail would 

benefit from opening stands. Vegetative treatments along with prescribed burning 

would follow Forest Plan Standard 3103, and would not result in cumulative 

impacts to known snail colonies.

would be expected to continue, 

changing the existing structural 

stages, with the majority of pine 

sites transitioning to SS1, 2, and

in decreased nesting habitat and 

may cause displacement. The threat

may cause short-term displacement of 

individuals. Unknown nests may be 

disturbed during harvest activities. Provides 

for habitat diversity. Would decrease existing 

MPB and wildfire risk. Spruce would not 

change from Alternative 1. 

Cumulative Effects

Would have adverse cumulative 

effects to habitat. Potential for 

long-term adverse cumulative 

effects due to stand replacing 

events. 

Past, present, and future activities are 

expected to continue in the project area, as 

well as on private lands. Alternative 2 would 

be expected to incrementally offset some of 

the effects of past fire suppression by 

reducing pine encroachment in spruce, 

meadow, and hardwood habitat through 

vegetation treatment activities. Treatment 

activities are expected to temporarily 

produce disturbance impacts to sharpshinned hawks. Mountain pine beetle is also 

expected to incrementally offset some of the 

above effects naturally by reducing pine 

encroachment into spruce, meadow, and 

hardwood habitat. However, because of the 

effects of MPB, there is expected to be 

adverse cumulative effects to sharp-shinned 

hawks because of loss of suitable nesting 

habitat. 

Private lands may continue to be developed, 

some of which may include roads. All may 

affect sharp-shinned hawks through direct 

mortality, modification of behavior, habitat 

alteration, spread of exotics, or disturbance. 

There are no known future activities which 

would affect spruce habitat. 

Summary

The No Action alternative retains the most suitable nesting habitat, with the most 

potential for more future nesting habitat than the proposed alternative. However, no 

SS3C is left because of MPB effects. The same amount of spruce is available in 

both alternatives. The proposed action is expected to increase hardwood acreage 

because of hardwood conversion treatments, although this habitat type for nesting is 

not significant. This alternative would contribute toward meeting Forest Objective 

221. This species is likely to persist on the Forest.

Would have adverse cumulative effects to 

nesting habitat, but to a lesser degree than No 

Action. Positive cumulative effects to other 

habitat components, including meadows, and 

hardwood stands. Short-term cumulative 

effects of disturbance. 

Summary

Both alternatives would reduce preferred nesting habitat, although Alternative 2

would provide the most acres of preferred nesting habitat, current and future. The 

potential for loss of habitat to fire or MPB is high in No Action, but reduced in 

Alternative 2. Known nests would be protected through Standard 3204. The 

alternatives would meet Forest Plan standards and guidelines and would contribute 

toward meeting Objective 221. Therefore this species is likely to persist on the 

Forest. 

Alternative 1

No Action

Alternative 2

Proposed Action

Broad-winged 

Hawk

(Buteo platypterus

Direct and Indirect Effects

The threat of stand replacing wildfire 

would increase. Pine stands may 

become denser. Conifers would 

continue to encroach into meadows 

and hardwoods. Expected MPB 

activity would cause most pines sites 

to transition to SS1, 2, and 3A, 

causing a decline in nesting habitat. 

Spruce and hardwoods may increase 

because of the effects of MPB on 

conifers.

Retains more preferred nesting habitat than 

No Action. Spruce acreage would remain 

the same as Alternative 1. Treatments 

would increase hardwood habitat. May 

cause temporary disturbance of unknown 

nests and displacement of individuals. 

Cumulative Effects

Would have adverse cumulative 

effects to nesting habitat. Potential 

for long-term adverse cumulative 

effects due to stand replacing events.

Cumulative effects to nesting habitat are 

offset by reduced potential for loss of 

habitat to fire and MPB. 

The action alternative is expected to 

incrementally offset some of the effects of 

past fire suppression by reducing pine 

encroachment into spruce, meadow, and 

hardwood habitat through vegetation 

treatment activities. Treatment activities are 

expected to temporarily produce disturbance 

impacts to broad-winged hawks, if present, 

but the impacts are expected to cease once 

the project is complete. Mountain pine 

beetle is also expected to incrementally 

offset some of the above effects naturally by 

reducing pine encroachment into spruce, 

meadow, and hardwood habitat. However, 

because of the effects of MPB, there is 

expected to be adverse cumulative effects to

Summary of Effects to SOLC

broad-winged hawks because of loss of 

suitable nesting habitat. 

Private lands would likely continue to be 

developed, some of which may include 

roads. All may affect broad-winged hawks 

through direct mortality, modification of 

behavior, habitat alteration, spread of 

exotics, or disturbance. Additionally, 

private lands most likely would continue to 

be thinned to reduce the threat of MPB.

Summary

Nesting habitat is probably the most important factor for long-term persistence of 

the broad-winged hawk. The proposed action proposes treatments that could

decrease the chances of stand replacement wildfire or MPB activity that may 

negatively impact the habitat desired by this species. The proposed action provides 

more acres of nesting habitat, although small in scale, for the broad-winged hawk. It 

also provides treatments in hardwoods that may increase nesting habitat within 

hardwood communities because of conifer removal treatments.

The proposed action would meet Forest Plan standards and guidelines, but because 

of MPB activity within the project area, little preferred nesting habitat would 

remain. The proposed action would contribute toward meeting Forest Objective 

221. This species is likely to persist on the Forest.

Alternative 1

No Action

Alternative 2

Proposed Action

Northern Sawwhet Owl

(Aegolius acadicus

Direct and Indirect Effects

Increased roosting habitat, but little 

to no nesting habitat would remain. 

High risk for loss of habitat to MPB

and fire. 

Preferred nesting habitat would be reduced, 

although more would remain than the No 

Action. Higher potential for future nesting 

habitat as more mature stands remain than 

No Action. Preferred roosting habitat would 

decrease substantially. Hardwood habitat 

would increase. 

Potential for short-term disturbance and 

displacement of individuals. 

Cumulative Effects

Adverse cumulative effects to 

nesting habitat. Potential for longterm adverse cumulative effects due 

to stand replacing events.

Cumulative effects to nesting habitat are 

offset by reduced potential for loss of 

habitat to fire and MPB. 

The action alternative is expected to 

incrementally offset some of the effects of 

past fire suppression by reducing pine 

encroachment into spruce, meadow, and 

hardwood habitat through vegetation 

treatment activities. Treatment activities are 

expected to temporarily produce disturbance 

impacts to northern saw-whet owls, but the 

impacts are expected to cease once the 

project is complete. Mountain pine beetle is 

also expected to incrementally offset some 

of the above effects naturally by reducing 

pine encroachment into spruce, meadow, 

and hardwood habitat. However, because of 

the effects of MPB, there is expected to be 

adverse cumulative effects under both 

alternatives to northern saw-whet owls

because of loss of suitable nesting habitat. 

Private lands would likely continue to be 

developed, some of which may include 

roads. All may affect northern saw-whet 

owls through direct mortality, although 

unlikely, modification of behavior, habitat 

alteration, spread of exotics, or disturbance. 

Additionally, private lands would continue 

to be thinned to reduce the threat of MPB.

Summary

Alternative 2 retains more nesting habitat, but less roosting habitat than No Action. 

Alternative 2 also increases the potential for retention and development of nesting 

habitat into the future. 

The proposed action would meet Forest Plan standards and guidelines. The 

proposed action would contribute toward meeting Forest Objective 221. This 

species is likely to persist on the Forest. 

Alternative 1

No Action

Alternative 2

Proposed Action

Pygmy Nuthatch

(Sitta pygmaea 

melanotis) 

Direct and Indirect Effects

Preferred nesting habitat would 

decrease substantially. Highest 

potential for snag habitat in the 

short-term, 5 years. Lowest 

potential for snag habitat long-term. 

The threat of loss of nesting habitat 

to wildfire would increase. 

Preferred nesting habitat would decrease, but 

less than No Action. Increased snag habitat, 

although less than No Action. Improved 

potential for development of preferred 

habitat. 

Potential for short-term disturbance and 

displacement.

Cumulative Effects

Greatest potential for adverse 

cumulative effects due to stand 

replacing events, MPB and fire. 

Adverse cumulative effects may occur 

because treatments, MPB, or both are 

expected to significantly decrease nesting 

habitat, although the proposed action would 

retain more nesting habitat than No Action. 

Potential for short-term disturbance 

cumulative effect. Mountain pine beetle is 

also expected to incrementally offset. 

However, because of the effects of MPB, 

there is expected to be adverse cumulative 

effects to pygmy nuthatches because of loss 

of suitable canopy cover in both alternatives. 

Cumulative benefit to snag habitat in short 

and long term. 

Summary

Alternative 2 provides more nesting habitat for the pygmy nuthatch than the No 

Action alternative. It also would decrease potential loss of habitat to wildfire. More 

mature trees would be expected to remain for replacement snags in the future in 

Alternative 2.

The proposed action would meet Forest Plan standards and guidelines and would 

contribute toward meeting Forest Objective 221. This species is likely to persist on 

the Forest.

Long-legged

Direct and Indirect Effects

Pine stands may become denser and 

provide larger future snags. 

Wildfire and MPB risk would be 

expected to increase. Conifers 

encroachment would continue in 

meadows and riparian zones. 

Current MPB activity would create

large pockets of snags; however, 

MPB-caused snags are expected to 

only remain standing for 5 years. 

Mature structural stages are 

expected to decrease significantly. 

Hardwoods, shrubs, and grasses 

may increase because of the MPB

killing conifers, potentially 

increasing prey species.

Potential impact to snag roosting habitat, but 

less than in the No Action. Higher potential 

for future large snag roosting habitat than No 

Action. May disturb/displace individual 

roosting bats in the short-term. Foraging 

habitat expected to increase.

Activities may decrease/slow-down snag 

recruitment because thinning units would be 

less susceptible to wildfire and insect 

outbreaks; however, MPB activity is 

expected to increase the amount of snags, in 

the short-term. 

Cumulative Effects

Foraging habitat may have both 

beneficial and adverse cumulative 

effects. 

The proposed action for this project is not 

expected to influence spread of white-nosed 

syndrome. There is only one known 

abandoned mine, which is gated to prohibit 

unauthorized entry. 

Possible cumulative impact of disturbance, 

short-term. 

Positive cumulative impact to foraging 

habitat. 

Possible adverse cumulative impact to snag 

roosting habitat, but less than in No Action. 

Summary

The proposed action is expected to provide the most habitat for bats and prey and the 

most potential for future large snags remaining on the landscape. Suitable roosting 

snags would also be available. There are abandoned mines within the project area, 

but standards, guidelines and design criteria would be implemented to protect the 

known mines used for roosting/hibernating. Therefore, impacts from the proposed 

action on these bat species should be minimal. 

The proposed action would meet Forest Plan standards and guidelines. Therefore, 

would contribute toward meeting Forest Objective 221. The northern long-eared, 

small-footed, long-eared and long-legged myotis bat species are likely to persist on 

the Forest.

habitat remains high. 

Habitat fragmentation is expected to 

occur.

Snag habitat would be increased

Direct mortality, although unlikely, from 

treatment activities may occur. Possible 

short-term disturbance. Possible long-term

with MPB activity, are expected to cause

Long term snag potential is improved over 

No Action.
Vestal Final Environmental Impact Statement Chapter 3

93

Summary of Effects to SOLC

decreased potential in the long term. Would reduce MPB and wildfire risk. 

Cumulative Effects

Activities such as vegetation management, fuels management, livestock grazing, 

recreational activities and other management activities have and are expected to 

continue within the project area. These activities would likely occur on private 

lands as well. Private lands would likely continue to be developed, some of which 

may include roads. All may affect flying squirrels through direct mortality, 

modification of behavior, habitat alteration, spread of exotics, or disturbance. 

Additionally, private lands would continue to be thinned to reduce the threat of 

MPB. Northern flying squirrels have relatively small ranges, generally less than 42 

acres (Cotton & Parker 2000), and are non-migratory. Privately-owned lands within 

and adjacent to the project boundary may also provide suitable northern flying 

squirrel habitat, but resource management and conservation by private citizens and 

companies depend on a number of factors (e.g., desired goals, market prices, 

development potential). Private lands managed for timber harvest may tend toward 

fewer acres in the late-successional stage forest and fewer snags. Potential northern 

flying squirrel habitat is assumed to occur on private lands across the project area; 

however, the extent and persistence of such habitat is uncertain.

Summary

Both alternatives affect habitat for the flying squirrel. However, the proposed action 

treats stands to mostly SS4A, and more acreage of SS 4B, 4C, and 5 would remain 

within the project area, providing little more habitat for this species. More future 

replacement snags would also be expected to remain on the landscape.

The proposed action would meet Forest Plan standards and guidelines. Therefore, 

the alternatives would contribute toward meeting Forest Objective 221. This 

species is likely to persist on the Forest.

Alternative 1

No Action

Alternative 2

Proposed Action

Meadow Jumping 

Mouse

(Zapus hudsonius 

campestris) 

Direct and Indirect Effects

No treatments in riparian areas 

would occur. Livestock grazing 

would continue and riparian grasses 

may continue to receive high 

seasonal use. Expected MPB

activity would increase hardwoods 

and meadows by killing more pine. 

This may increase quality habitat 

for this mouse species.

Possible direct effects from proposed 

activities. 

Treatments would enhance meadow and 

riparian hardwood habitat. 

Cumulative Effects

Activities such as vegetation management, fire suppression, livestock grazing, 

recreational activities and natural events such as drought and flooding have caused 

impacts to riparian areas within the project area. Fire suppression has resulted in an 

increase of pine trees which may lead to a change in water tables. Other 

management activities have and will continue in and adjacent to the project area. 

These activities would likely occur on private lands as well. Private lands would

likely continue to be developed, some of which may include roads. All may affect 

jumping mice through direct mortality, modification of behavior, habitat alteration, 

spread of exotics, or disturbance. 

Private lands occur frequently within riparian areas. These private lands provide 

suitable habitat, but conditions may have been altered by private land management 

activities such as livestock grazing or draining to convert to drier site conditions for 

subsequent haying. 
Vestal Final Environmental Impact Statement Chapter 3

94

Summary of Effects to SOLC

Summary

Neither of the alternatives is expected to cause detrimental impacts to riparian areas 

within the project area. The proposed action proposes timber treatments to enhance 

hardwoods and meadows next to riparian streams, which is expected to benefit this 

species. Therefore, the proposed action would move the riparian areas to better 

condition overall in the project area. 

The proposed action would meet Forest Plan standards and guidelines. Therefore, 

the alternatives would contribute toward meeting Forest Objective 221. This species 

is likely to persist on the Forest.

Alternative 1

No Action

Alternative 2

Proposed Action

Mountain Goat

(Oreamnos 

americanus)

Direct and Indirect Effects

Due to expected MPB activity pine 

stands would become more open 

increasing forage habitat, travel 

corridors and cover. The increased 

forage and decrease in dense pine 

sites, especially on Buckhorn 

Mountain, may improve habitat 

enough to provide the opportunity 

for a population increase.

No direct effects are expected to occur due to 

project activities. However, vegetation 

treatments may disturb individuals in the 

short-term. The increased forage and 

decrease in dense pine sites, especially on 

Buckhorn Mountain, may improve habitat 

enough to provide the opportunity for a 

population increase.

Cumulative Effects

Treatment activities are expected to temporarily produce disturbance impacts to this 

species in addition to those from recreation activities, but the impacts are expected 

to lessen once the project is complete; however, recreational disturbance is expected 

to continue. The proposed action could incrementally lead to additional invasive 

weeds, but include control activities to mitigate these impacts. Both alternatives are 

expected to increase forage (grasses/forbs and browse) for these species, which may 

incrementally reduce conflicts and competition with grazing livestock. However, 

the proposed action includes vegetation treatments that are expected to further 

enhance forage. Although there could be short-term adverse indirect effects to this 

species from the proposed action, adverse cumulative effects are not expected. 

Because of current MPB activity, spruce stands and dense stands of pine are 

expected to be greatly reduced. This is expected to benefit this species. 

Summary

Both alternatives increase foraging habitat. However, the proposed action also 

includes prescribed burning to maintain clearcuts created for mountain goat forage. 

The proposed action would meet Forest Plan standards and guidelines. Therefore, 

this project would be consistent with Forest Plan Objective 221 for mountain goat. 

This species is likely to persist on the Forest.

Region 2 (R2) Sensitive Species

Summary of Effects on Sensitive Species

The following is a summary of effects to wildlife Sensitive Species. A detailed analysis 

can be found in the Wildlife and Fisheries Biological Assessment/Biological Evaluation

in the project record. 

Region 2 has implemented a closure order, as of July 2010, for all caves and abandoned 

mines in an attempt to prevent spread of white-nosed syndrome, a fungal disease that has 

caused the death of over one million bats in the northeastern United States. This is not a 

concern in the Vestal project area because there is only one known abandoned mine, 

which had a bat gate installed in 2008 to inhibit unauthorized entry. The proposed action 

for this project is not expected to influence spread in the area.

Fringed Myotis

(Myotis

Direct and Indirect Effects

Fire hazard and MPB risk would 

remain high. Short-term increase in 

snags used for roosting, but 

substantial decrease in mature pine 

as roosting habitat. Potential 

increase in foraging habitat 

(riparian areas, meadows). 

Increase in snag roosting habitat, but less 

than in Alternative 1. Reduced MPB risk 

and fire hazard increases potential for 

maintaining roosting habitat long-term. 

Foraging habitat is expected to improve. 

Potential for disturbance of roosting bats. 

Cumulative Effects

Incremental impacts to roosting 

habitat are expected as MPB

continues to reduce mature habitat, 

but create snags, on both National 

Forest and private lands. 

The proposed action for this project is not 

expected to influence spread of white-nosed 

syndrome. There is only one known 

abandoned mine, which is gated to prohibit 

unauthorized entry.

Incremental impacts to habitat quantity are 

expected to be minimal because direct and 

indirect impacts are expected to be minimal. 

The incremental impacts of disturbance are 

expected to be minimal because bats are 

normally active during the night when 

project activities would be minimal.

Summary

The alternatives ‘may adversely impact individuals, but not likely to result in a 

loss of viability in the Planning Area, nor cause a trend toward federal listing’.

The proposed alternative would be consistent with these standards and guidelines. 

The Forest is conserving and enhancing habitat (Objective 221) for this species 

through cave, mine and snag management. This species is likely to persist on the

prey for bats. 

Possible long-term loss of roosting

Potential for direct impacts and disturbance. 

Reduced fire hazard. Possible long-term 

loss of roosting habitat due to MPB activity, 

but to a lesser degree than No Action. 

Prescribed burning could affect air quality in

the loss of existing snag roost habitat. Fire is 

known to affect insect populations which 

could reduce prey items for bats foraging in 

the area. 

Cumulative Effects

Incremental impacts to habitat 

quantity are expected to be 

minimal. 

The proposed action for this project is not 

expected to influence spread of white-nosed 

syndrome. There is only one known 

abandoned mine, which is gated to prohibit 

unauthorized entry.

Incremental impacts to habitat quantity are 

expected to be minimal for both alternatives 

because direct and indirect impacts are 

expected to be minimal. The effects of 

disturbance are expected to be minimal since 

bats are normally active during the night 

when project activities would be minimal.

Summary

The alternatives ‘may adversely impact individuals, but not likely to result in a 

loss of viability in the Planning Area, nor cause a trend toward federal listing’.

The proposed action would likely have the more impact on the bat species due to the 

larger acreage of treatment, but it is also expected to retain more live trees into the 

future. The proposed action would meet Forest Plan standards and guidelines. The 

Forest is conserving and enhancing habitat for this species through cave and mine 

management therefore, both alternatives contribute to conservation of bat habitat

would reduce prey for bats. 

MPB activity is expected to 

continue and may result in longterm loss of roosting habitat. 

Potential for direct impacts and disturbance. 

Reduced fire hazard. Short-term decrease in

Prescribed burning could affect air quality in 

cave and mine roosts, and may contribute to

Summary of Effects on R2 Sensitive Species

Cumulative Effects

Mountain pine beetle activity will 

continue in the project area. 

Increased pine beetle activity and 

wildfire would create additional 

dead trees (potential for roosting) 

and grass/forb structural stage 

which could increase prey base for 

this species; however roosting 

habitat would be lost. These 

activities would likely occur on 

private lands as well. Private lands 

would likely continue to be 

developed, some of which may 

include roads. All may affect bats 

through direct mortality, 

modification of behavior, habitat 

alteration, spread of exotics, or 

disturbance.

The proposed action for this project is not 

expected to influence spread of white-nosed 

syndrome. There is only one known 

abandoned mine, which is gated to prohibit 

unauthorized entry.

Activities such as vegetation management, 

fuels management, livestock grazing, 

recreational activities and other management 

activities have and will continue. Mountain 

pine beetle activity will continue in the 

project area. Increased pine beetle activity 

and wildfire would create additional dead 

trees (potential for roosting) and grass/forb 

structural stage which could increase prey 

base for this species; however roosting 

habitat would be lost. These activities would

likely occur on private lands as well. Private 

lands would likely continue to be developed, 

some of which may include roads. All may 

affect bats through direct mortality, 

modification of behavior, habitat alteration, 

spread of exotics, or disturbance.

Summary

The alternatives ‘may adversely impact individuals, but not likely to result in a 

loss of viability in the Planning Area, nor cause a trend toward federal listing’.

The proposed action may limit individual use of treated areas but would not be 

expected to affect species viability throughout the planning area. Habitat for this 

species is expected to remain because both live coniferous and deciduous trees are

expected to remain on the landscape. The Forest is conserving and enhancing habitat 

and this project contributes to Objective 221.

Direct and Indirect Effects

No direct or indirect effects. Potential direct effects on individuals. 

Potential short-term disturbance. Habitat is 

expected to improve with removal of pine 

within the known colony. Preferred habitat 

may increase for this species.

Cumulative Effects

No cumulative effects Livestock grazing does occur and could lead 

to expansion of black-tailed prairie dog 

habitat. Recreational shooting does occur 

within the prairie dog town. There is always 

a risk of disease (sylvatic plague) that can 

eliminate local prairie dog populations. 

Wildfires may occur, creating openings and, 

thus, increasing the quantity and quality of 

grassland forage available to livestock and 

wildlife. Development on private lands 

within the project area could occur, 

decreasing acreage for this dogtown. 

Additionally, human intolerance of the 

species is expected to continue, decreasing

numbers.

Summary

The determination of ‘may adversely impact individuals, but not likely to result 

in a loss of viability in the Planning Area, nor cause a trend toward federal 

listing’. The No Action alternative would have ‘no impact’. The Forest is meeting 

Objective 237 which prompts the Forest to manage for 200-300 acres of prairie dog 

towns in at least 3 different towns (USDA Forest Service 2009).

The proposed action would meet Forest Plan standards and guidelines. The Forest is 

conserving and enhancing habitat for this species and is contributing to Objective 

221. Therefore, this species is likely to persist on the Forest.

Alternative 1

No Action

Alternative 2

Proposed Action

American marten

(Martes 

americana)

Direct and Indirect Effects

No direct effects. MPB activity 

would reduce preferred dense mature 

habitat, but may also increase down 

woody material. Preferred spruce 

habitat would remain. 

Possible direct effects on individuals. 

Impacts to marten from any logging 

activities would mainly be in stands 

adjacent to occupied habitat. Potential for 

short-term displacement. No change to 

spruce stands. Treatments and MPB caused 

mortality would reduce the amount of dense 

pine stands and could reduce prey habitat 

and future downed woody material desired 

by marten. However, it is expected that 

downed woody material already present 

would not be moved and would remain in 

those areas, and MPB-killed trees would 

fall, creating sufficient downed material. In 

addition, treatment to pine adjacent to 

spruce stands is expected to reduce, in the 

long-term, the wildfire risk to spruce 

habitat. 

Cumulative Effects

Cumulative effects from MPB

caused mortality on private lands. 

Vegetation treatments and 

development on private lands may 

also add to impacts. 

Very little marten habitat occurs on forest. 

Cumulative effects from vegetation 

management actions that remove spruce, 

drastically reduce forest canopy, or remove 

large down woody debris would reduce 

available habitat for the species. Recreation 

in suitable habitat may have and may 

continue to impact the American marten.

Where private lands include high quality 

habitat, it could be subject to low-density 

development (e.g., rural residences). 

Landowners may be conducting thinning 

activities to protect their homes and viewshed from MPB and/or high fuel loading. 

Furthermore, they would not likely apply 

any mitigation to minimize effects to 

marten. Due to the combination of these 

factors, habitat on the Forest would likely 

become more important.

Summary

The both alternatives ‘may adversely impact individuals, but not likely to result 

in a loss of viability in the Planning Area, nor cause a trend toward federal 

listing’.
Vestal Final Environmental Impact Statement Chapter 3

Summary of Effects on R2 Sensitive Species

Little preferred spruce habitat is contained within the project area. The proposed 

action would retain more dense, mature habitat than the No Action alternative. 

However, the proposed action proposes treatments to improve stand health and 

reduce the risk of wildfire, thus, retaining more acres of dense, mature trees for 

connectivity. The proposed action contributes to conservation of marten habitat 

(Forest Plan Objective 221).

The proposed action would meet these standards and guidelines. Fire suppression

during the last century has allowed spruce to increase in abundance and density in 

the Black Hills. The Forest is conserving habitat for the American marten (USDA 

Forest Service 2010). Therefore, this species is likely to persist on the Forest.

Alternative 1

No Action

Alternative 2

Proposed Action

Bald Eagle

(Haliaeetus 

leucocephalus)

Direct and Indirect Effects

Expected MPB activity would create 

snags for roosting by killing large 

trees; these snags are expected to 

remain for only five years. Potential 

long-term future roosting trees would 

be reduced due to MPB caused

mortality of large trees. 

No direct effects are expected. Individuals 

may be displaced temporarily. 

Mountain pine beetle are expected to kill 

large trees creating snags for roosting, but to 

a lesser degree than No Action. Therefore, 

the potential to maintain large trees for 

future roosting sites is improved over No 

Action. 

Cumulative Effects

Cumulative effects expected MPB 

caused mortality continues on private 

lands. Treatments to reduce MPB

risk on private lands would also 

remove roosting trees. 

Incremental impacts to habitat quantity are 

expected to be minimal because direct and 

indirect impacts are expected to be minimal; 

however, there may be some incremental 

impacts from disturbance and from MPB

activity killing roosting trees.

Summary

Both alternatives would have ‘no impact’ on the bald eagle.

This project would be implemented consistent with any of the relevant standards, 

guidelines that protect bald eagles or provide for eagle habitat, and contributes to 

Objective 221.

Alternative 1

No Action

Alternative 2

Proposed Action

Northern 

goshawk

(Accipiter gentilis)

Direct and Indirect Effects

No direct effects. Expected MPB 

activity would reduce nesting 

habitat, but increase foraging 

habitat. High fire hazard remain 

and is a threat to suitable nesting 

habitat. Some prey species would 

benefit by increasing grasses and 

forbs (cover and food source) or 

young-forest conditions, while other 

prey species that favor a mature 

over-story may decrease.

No direct effects to known nests, potential 

for direct effects to unknown nests. Would 

enhance and protect goshawk nesting areas 

by reducing MPB risk and fire hazard. 

Would retain more suitable nesting habitat 

than No Action. Increase in foraging habitat. 

Some prey species could be adversely 

affected as well by removing canopy, snags, 

down woody material and ground cover. 

Similar impacts to prey species as No Action. 

Cumulative Effects

Past timber harvest has contributed 

to the loss of large mature trees, and 

blocks of mature, dense forested 

stands have been reduced in size so 

that they are no longer considered 

Past timber harvest has contributed to the 

loss of large mature trees, and blocks of

large enough to meet the nesting 

requirements for the goshawk. 

Wildfires and MPB have also 

contributed to the loss of large 

mature pine trees in the area. 

requirements for the goshawk. Wildfires and

MPB have also contributed to the loss of 

large mature pine trees in the area. The 

proposed action would continue to remove 

potential nest trees, but would provide 

protection around the existing nest territory. 

The possibility of future large-scale, high

intensity wildfires does exist for this project 

area. Development and vegetation treatment 

of private lands is expected to continue. Any 

changes to this acreage are not expected to 

contribute to habitat loss. Incremental 

impacts from the proposed action are 

expected to offset some of the potential 

effects of large wildfires and insect 

epidemics that result from past, present and 

future fire suppression. However, because of 

MPB activity that is already occurring and 

expected to occur throughout the entire 

project area, large trees are expected to 

significantly decrease. 

Summary

Both alternatives ‘may adversely impact individuals, but not likely to result in a 

loss of viability in the Planning Area, nor cause a trend toward federal listing’.

Alternative 2 would provide more dense habitat, and SS4A habitat that may increase 

more quickly to become suitable nesting habitat, than No Action. The proposed 

action would meet Forest Plan standards and guidelines, and meet Objectives 221. 

Mountain pine beetle is expected to reduce habitat, but the effects would be lessened 

in Alternative 2, because more suitable habitat would remain. Therefore, this 

species is likely to persist on the Forest. 

Alternative 1

No Action

Alternative 2

Proposed Action

Flammulated owl

(Otus flammeolus)

Direct and Indirect Effects

High potential for loss of large tree 

habitat from MPB mortality and 

wildfire. Reduction of preferred 

habitat due to expected MPB caused 

mortality. 

Potential direct effects. Potential short-term 

disturbance. Potential reduction of preferred 

habitat by removing large over-story trees, 

and possibly removing snags (if within snag 

cutting areas or if safety hazards to harvest 

operations). Would retain more preferred 

habitat than the No Action. Structural stage 

4A, open park-like pine forest, would

increase greatly. Increase in prey population 

may occur from activities that release 

understory vegetation, thus improving insect 

and small mammal habitat. Sufficient 

downed woody material would be expected 

to remain because of snags falling. Would 

increase potential for maintaining mature 

pine habitat long-term by reducing MPB

susceptibility and fire hazard.

Cumulative Effects

Large areas of snag habitat have been made available from insect outbreaks in the 

Black Hills and the Vestal project area, and large expanses of MPB-killed trees are 
Vestal Final Environmental Impact Statement Chapter 3

101

Summary of Effects on R2 Sensitive Species

expected to cover the landscape. However, these ‘open areas’ are not considered 

preferred flammulated owl nesting habitat. They may improve prey species 

abundance on a general scale. Mature trees, relatively open, park-like, stands are

considered more suitable habitat. Timber harvesting, on public or private lands, that 

removes mature overstory, and a loss of snags would reduce potentially suitable 

habitat.

Summary

Both alternatives ‘may adversely impact individuals, but not likely to result in a 

loss of viability in the Planning Area, nor cause a trend toward federal listing’.

This project is consistent with pertinent standards and guidelines and contributes to 

Objective 221. However, due to the low occurrence of this species on the Forest in 

relation to the amount of potentially suitable habitat, no alternative is likely to affect 

the colonization by or establishment of flammulated owls on the Forest. 

Alternative 1

No Action

Alternative 2

Proposed Action

Black-backed 

woodpecker

(Picoides arcticus)

Note: is also a 

Forest MIS

Direct and Indirect Effects

Increased habitat in the short-term 

due to expected MPB activity. 

MPB risk and wildfire risk is very 

high. If wildfire were to occur, 

more habitat in the short-term 

would be available because of their 

association with burned areas. Has 

greatest potential for increase in 

woodpecker habitat in the shortterm, but has greatest decrease in 

dense habitat types that are used 

when no burned or MPB habitat is 

available. 

Snags would increase due to natural 

mortality. 

In the short-term, habitat would be provided 

as MPB caused mortality continues. 

Treatments to reduce MPB risk are expected 

to result in less mortality than No Action. 

Reduced fire hazard. Proposed actions are 

expected to retain more mature, dense stands 

(SS4B, 4C and 5) than the No Action. 

Snags would be plentiful in the short-term. 

Potential for accidental removal of 

snags/cavities being used by woodpeckers. 

Prescribed burning may destroy snags, but 

may also create snags. Greatest potential to 

create future (long-term) nest snags for this 

species. 

May disturb nesting woodpeckers if harvest 

occurs during nesting season, expected to be 

a short-term impact. 

Cumulative Effects

Past wildfires and past and existing 

MPB infestations have created habitat 

throughout the Forest and project area. 

Continued MPB activity throughout the 

forest and project area would continue to 

provide habitat for this species. Fuel 

(fire) management treatments would 

reduce habitat potential for this species. 

Privately owned lands within and 

adjacent to the project area may also 

provide suitable habitat for the blackbacked woodpecker. Fire-hazard and 

MPB reduction activities are likely to 

increase on some of these lands in effort 

to prevent loss from wildfire. Cutting of 

snags for fuelwood may reduce the 

number of snags. This could result in a 

loss of habitat, but the amount of area 

within these private lands is relatively 

small compared to what is on the forest 

(USDA Forest Service 2008). The 

indirect effects mentioned above would 
Vestal Final Environmental Impact Statement Chapter 3

102

Summary of Effects on R2 Sensitive Species

be an incremental impact additional to 

those on private lands. 

Summary

The alternatives ‘may adversely impact individuals, but not likely to result in a 

loss of viability in the Planning Area, nor cause a trend toward federal listing’.

Alternative 1 has the greatest potential for increasing woodpecker habitat. 

Alternative 2 may decrease preferred and/or potential habitat, but would not affect 

the habitat or population trend Forest wide because of providing for Objective 211

(snags). Snags are not allowed to be cut unless deemed a safety hazard or within 

designated firewood cutting areas. The project area is only a small portion of the 

currently available habitat, new habitat acres are currently being created across the 

Forest. 

Habitat conditions would be provided, consistent with Objective 238b. The 

proposed action alternatives would meet Forest Plan standards and guidelines; 

therefore this species is likely to persist on the Forest. 

Alternative 1

No Action

Alternative 2

Proposed Action

Northern leopard 

frog

(Rana pipiens)

Direct and Indirect Effects

Reductions in canopy density may 

cause surface temperature and soil 

moisture (drying) changes that 

would not favor this species.

Potential direct effects. Potential for habitat 

disturbance or loss. Reductions in canopy 

density may cause surface temperature and 

soil moisture (drying) changes that would not 

favor this species. Noxious weed treatment 

may potentially affect water quality and plant 

species diversity. Risk of MPB and wildfire

would be expected to decrease, which is 

expected to reduce the risk of post-fire flood, 

erosion and sedimentation in riparian habitat. 

Cumulative Effects

Livestock grazing at breeding sites (streams) is expected to negatively impact this 

species. Recreational activities that use and/or impact streams (e.g., horse and OHV

trails through streams) are occurring and will continue to occur. Available habitat 

could be supplemented if harvests increase spring/seep water yields, new 

springs/seeps surface, or if soil moisture levels are maintained. Decreasing soil 

moisture through timber harvest, slash/fuels disposal projects, and the disposal of 

existing down woody material (fuel treatments) is expected to continue to reduce 

adult foraging habitat and adversely affect dispersal. Wildfires have removed 

canopy which can unfortunately increase ground temperatures, and may limit 

distribution of this species the Forest. At sites where there are introduced predatory 

fish, leopard frog productivity has been adversely affected (Smith & Keinath 2007). 

Incremental impacts to habitat quantity are expected to be minimal because direct 

and indirect impacts are expected to be minimal. 

Summary

The alternatives ‘may adversely impact individuals, but not likely to result in a 

loss of viability in the Planning Area, nor cause a trend toward federal listing’.

The proposed action would meet Forest Plan standards and guidelines. The 

proposed action would meet the intent of Objectives 213 and 221, and continue to 

provide habitat for the northern leopard frog. Therefore, this species is likely to 

persist on the Forest.

Direct and Indirect Effects

Potential direct impacts. Potential habitat 

disturbance or loss may occur from road 

reconstruction. Reductions in canopy density 

may cause surface temperature and soil 

moisture (drying) changes that would not 

favor this species. Noxious weed treatments

may potentially affect water quality and plant 

species diversity. Expected to enhance 

habitat by providing protection to riparian

areas. 

Cumulative Effects

May be directly impacted by livestock grazing and recreationists in suitable habitat. 

Timber harvesting, fuel treatments, and thinning where this species is present (den 

sites) may adversely alter site conditions (e.g. warming, drying, soil compaction, and 

den disturbance). Recreation is expected to continue and would negatively impact 

this species. Livestock overgrazing in riparian areas degrades potential suitable 

habitats through trampling, sedimentation, loss of vegetation, and effects to water 

quality, chemistry, and temperature. Additional levels of these impacts to riparian 

areas are not expected from the proposed action. The proposed action is expected to 

offset some of the adverse effects of past and present fire suppression by reducing 

the potential risk of fire and insects. 

Summary

The No Action alternative would have “No Impact”.

The proposed action ‘may adversely impact individuals, but not likely to result 

in a loss of viability in the Planning Area, nor cause a trend toward federal 

listing’. 

The proposed action would meet the intent of Objectives 213 and 221, and continue 

to provide habitat for the redbelly snake.

Proposed Action

Mountain sucker

(Catostomus

NOTE: also a 

Forest MIS

Direct and Indirect Effects

No direct or indirect effects Slight potential for direct effects. 

Indirect effects resulting from changes to 

aquatic/riparian habitat are anticipated to be 

negligible. 

Proposed road crossing on French Creek 

would result in some streambank disturbance 

and sediment input/mobilization. Potential 

adverse indirect effects would largely be 

avoided by installing a temporary bridge 

rather than culverts and fill, to minimize 

sediment input into French Creek. Adverse 

effects are further reduced because of the 

small area of disturbance, approximately 30 

feet of stream length, resulting from the 

crossing.

Cumulative Effects

No cumulative effects The proposed action is likely to have a 

discountable cumulative effect. Inwater 

construction activities at the road-stream 

crossing on French Creek may have a minor 
Vestal Final Environmental Impact Statement Chapter 3

104

Summary of Effects on R2 Sensitive Species

incremental impact regarding sediment input. 

This negative impact would be additive to 

other sediment input resulting from ongoing 

road use/maintenance and livestock grazing 

on public and private land adjacent to French 

Creek. Overall, assigned fisheries beneficial 

uses are likely to be maintained. Non-native 

fish populations would persist that may 

negatively impact the mountain sucker. 

Stream fragmentation remains largely 

unchanged due to Stockade Dam and perched 

culverts on lower French Creek.

Summary

The alternatives ‘may adversely impact individuals, but not likely to result in a 

loss of viability in the Planning Area, nor cause a trend toward federal listing’.

Mountain sucker viability is not at risk due to the minor amount of aquatic habitat 

affected and the low magnitude of potential direct or indirect adverse effects. 

Project is consistent with Objective 221. 

Alternative 1

No Action

Alternative 2

Proposed Action

Cooper’s 

mountain snail

(Oreohelix strigosa 

cooperi)

Direct and Indirect Effects

Beetle caused mortality is expected 

to diminish dense conifer stand 

conditions that would protect these 

snails from environmental 

conditions and desiccation. 

Increased potential for standreplacing wildfires, which could 

eliminate localized colonies and 

reduce suitable habitat both shortterm and long-term

Potential for direct effects. 

Retains more dense canopy than No Action. 

Colonies would likely expand where suitable 

habitat is present.

Sanitation of beetle infested trees within 

Frest sites may cause short-term impacts, but 

would retain more suitable habitat in the 

long-term.

Cumulative Effects

Drought can have negative impacts on this species by reducing moist site 

requirements necessary to sustain colony number. The loss of overstory due to MPB

mortality and the high probability of large-scale wildfire could reduce moist site 

conditions depending on size of openings and severity/intensity of fire. High 

intensity fire may destroy colonies and their habitat, isolate colonies, and reduce 

decay material necessary for their life cycle, which may last long-term. The 

proposed action is expected to reduce the potential for MPB and large wildfires 

which is expected to incrementally offset some of the effects of past fire 

suppression. Forest management activities, including livestock grazing, fuel 

treatments, recreation, and prescribed burning, in Vestal and in adjacent areas can 

increase isolation and increase xeric conditions that would limit snail colony 

expansion or extirpate localized colonies. Effects discussed above would

incrementally increase impacts when added to the impacts of these past and present 

activities. Roads improved or constructed for the proposed action are expected to 

incrementally add to these impacts while the treatments are underway, but these 

additional impacts are expected to cease following project completion as temporary 

roads are closed.

Forest.

Alternative 1

No Action

Alternative 2

Proposed Action

Regal fritillary 

butterfly

(Speyeria idalia)

Direct and Indirect Effects

No direct effect to this species or its 

habitat. MPB infestation would

continue to reduce canopies, 

possibly creating additional habitat 

for the butterfly. High fire hazard

would remain and be a threat to 

habitat. 

Potential direct effects. 

Treatments to maintain grassland habitat may 

improve nectar/host plant species. Indirect 

effects to butterfly habitat may occur from 

prescribed fire, noxious weed treatment, 

placement of landings, road placement and 

crossings, especially if located along the 

margins of streams. These effects would 

likely result in loss of host and nectar species 

short-term. 

Has a higher potential for the spread of 

invasive species that may affect this 

butterfly’s habitat long-term, than No Action. 

Design criteria is included to protect riparian 

habitats, provide down woody material, and 

restore disturbed areas with native species. 

Treatment effects are expected to be minimal 

to riparian diversity and nectar/host plant 

species. 

Cumulative Effects

Fire suppression and increase in conifer cover in grasslands and riparian areas may 

increase over time, negatively affecting this species. Additionally, risk of largescale wildfire or prescribed burning may negatively affect regal fritillary habitat 

short-term. The ‘proposed action’ is expected to offset some of the effects of past 

fire suppression by reducing pine encroachment into meadows and by reducing the 

risk of large-scale wildfires. Livestock grazing in prairies, upland meadows, 

hardwoods, and riparian zones may negatively affect this species. Prescribed 

burning in these areas could further reduce grasses, adding to these effects. 

Chemical use to control noxious weeds would decrease vegetation diversity in 

treated sites. Vegetation treatments may lead to more invasive weed infestations, 

which would lead to additional effects from chemical control. Fragmentation of 

habitat due to roads and trails may increase disturbance. Roads used under the 

proposed action may add to those disturbances temporarily, but the effects are 

expected to cease following project completion. A portion of the meadows and 

grasslands occur on private land. Heavy livestock use, recreation, and development 

on private land could negatively affect butterfly habitat. Under the ‘proposed 

action’, treatments that reduce pine encroachment into meadows may offset some of 

the loss of habitat occurring on private lands. 

Summary

The No Action alternative would have “No Impact”.

The proposed action ‘may adversely impact individuals, but not likely to result 

in a loss of viability in the Planning Area, nor cause a trend toward federal 

listing’. The proposed action contributes to conservation of butterfly habitat, Forest 

plan Objective 221. The proposed alternatives would meet Forest Plan standards 

and guidelines. Therefore, this species is likely to persist on the Forest. 
Vestal Final Environmental Impact Statement Chapter 3

Demand Species

Rocky Mountain Elk (Demand Species)

Alternative Effects Summary

The No Action alternative would increase early successional vegetative stages the most, 

which would provide more forage for elk. The proposed action would provide more SS 

4B, 4C, and 5 (although on a small scale), which is needed for cover. Additionally, more 

SS 4A, which would be expected to become cover in the long-term, would be created and 

would provide for more cover in the long-term. The proposed action implements 

treatments that may conserve larger trees that hopefully remain in groups that could 

provide potential cover, even if it is a 4A stand overall. The proposed action includes 

prescribed burning which may decrease hiding and calving cover, which is limited in 

areas of the project. However, prescribed burning may increase forage quantity and 

quality for elk. Aspen acreage is increased through the proposed action due to hardwood 

conversion. An increase in forage with a similar decrease in cover is expected with both 

alternatives, although the proposed action would retain more dense habitat conditions. 

Screening cover along the arterial and collector roads would be sufficient under either 

alternative because of topography, although the proposed action includes some design 

criteria to retain small trees along certain roads after vegetation treatments have occurred.

Guideline 3203 is currently being met on all arterial and collector roads within the project 

area and would be met following implementation. Miles of open road does not change by

alternative. 

Assuming Forest Plan standards are met, both alternatives would allow the Forest-wide 

elk population to remain stable, and would allow for the attainment of Forest Plan 

Objective 217. 

Cumulative Effects

The No Action alternative would not have adverse cumulative effects on this species as 

no direct or indirect effects would occur. 

Many of the private land in-holdings in the project area are currently used for summer 

livestock grazing and the grass is considered livestock forage. By the end of the grazing 

season, little usable herbaceous cover remains on these private lands. Livestock grazing 

on the Forest lands also affects habitat for elk by decreasing forage in riparian areas and 

meadows, thereby resulting in competition between livestock and wild ungulates. 

Habitat loss or degradation adds cumulatively to other effects influencing elk in the 

project area. Fire suppression and forest succession have increased the amount of pine 

across the landscape and decreased meadows, riparian areas, and hardwood stands over 

the last 100 years. Logging, thinning, pine beetle activity, prescribed burns and wildfires 

have resulted in a general increase in preferred forage habitat over time. These activities 

have opened up the pine overstory creating openings, enhancing and expanding 

hardwood understories and riparian areas. However, these same activities have 

decreased cover.

Roads within the project area are used for multiple uses (e.g. ranchers, allotment 

monitoring, weed control, recreational use, logging, etc.). Disturbance and potential road 
Vestal Final Environmental Impact Statement Chapter 3

107

kills from vehicular traffic may occur on system roads as well as roads through the 

county and private land. Hunting directly affects elk in the project area. Indirect human 

disturbance due to hunting also reduces habitat security for native ungulates. 

There are foreseeable future activities that may impact elk cover and forage within and 

adjacent to the project area. These activities include thinning, prescribed burning, 

hardwood release, hardwood regeneration and pine encroachment treatment. All of these 

activities would be expected to increase the amount and diversity of forage available for 

elk while reducing cover.

Merriam’s Wild Turkey (Demand Species) 

Alternative Effects Summary

Loss of habitat under both alternatives is expected with the MPB reducing cover and 

roosting habitat. Additionally, under the proposed action, there could be direct effects 

from project activities and incremental impacts from disturbance. However, the proposed 

action provides vegetation treatments that are expected to maintain dense habitat (SS 4B, 

4C, and 5) for roosting and winter, although it may not be sufficient to maintain a large 

population of birds. Foraging habitat would be sufficient with both alternatives. The 

proposed action is also expected to retain more mature pine stands in the form of SS 4A 

than the No Action alternative, due to the reduction of MPB susceptibility. These SS 4A 

stands are expected to develop into dense, mature pine stands much more rapidly than 

stands which are converted to SS 1 or SS 2. Design criteria is included to retain turkey 

roost trees as noted in guideline 3205. 

Cumulative Effects

Past timber harvest, wildfires, livestock grazing, recreation and drought have impacted 

the turkey populations in the project area, and these activities would likely continue. 

Spring weather is probably the single most significant factor in determining turkey 

populations. Hunting pressure can also affect population levels. Livestock grazing in 

conjunction with or independent of drought can reduce herbaceous vegetation, which is 

important in maintaining a high quality summer brood habitat (Rumble & Anderson 

1996). These activities would likely occur on private lands as well. Private lands would 

likely continue to be developed, some of which may include roads. All may affect 

turkeys through direct mortality, modification of behavior, habitat alteration, spread of 

exotics, and disturbance. Additionally, private lands would continue to be thinned to 

reduce the threat of MPB. 

No adverse cumulative effects are expected under the No Action alternative.

Migratory Birds

Golden Eagle (Migratory Bird)

Contiguously forested habitats, which currently make up a large portion of the Vestal

project area, are not preferred by golden eagles, but they may be included in a home 

range if suitable nesting or foraging habitat is intermixed. The Vestal project area 

contains limited areas, although present, e.g., Buckhorn Mountain, of rim-rock outcrops 
Vestal Final Environmental Impact Statement Chapter 3

108

and substantial cliffs or rock faces that provide typical nesting substrates. Eagles could 

forage in the forest meadows, or in nearby grasslands and large burned forest areas. 

Pine encroachment, commercial and non-commercial thinning, and prescribed burning 

treatments proposed for the Vestal project may have a positive effect on foraging habitat 

because it may open up the project area. Additionally, MPB activity is expected to kill 

large amounts of pine, opening up the area, potentially providing more foraging or 

nesting opportunities. 

Fire and Fuels

Affected Environment

The ponderosa pine cover type dominates the landscape and as a result of fire exclusion, 

ponderosa pine has encroached on the non-forested communities, contributing to the 

reduction in size of the hardwood cover type, creating dense, closed canopy ponderosa 

pine stands. Surface fuels include duff, small woody debris, dead down logs and long 

needle litter. Isolated areas of storm damage, and slash from past management activities 

exist within the project area.

In light of the recent and projected insect activity within the project area, changes in fuels 

profiles are expected. Insect damage would alter several stand characteristics including 

canopy fuels, down woody fuels, duff, ladder fuels, herbaceous fuels, and microclimate, 

in turn altering the fire hazard and potential fire behavior. 

The project area is located entirely in Custer County, South Dakota, with the City of 

Custer being the center for the project area. According to the 2010 census, the City of 

Custer has a population of just over 2,000. In recent years, several large fires have 

affected Custer County and private property and developed lands adjacent to national 

forest having burned over 100,000 acres in Custer County since 1997. The Vestal project 

area has not been impacted by large fire, but the area remains continually vulnerable. 

The City of Custer has been identified as an At-Risk Community (ARC) as defined from 

the Federal Register (66FR 43384, 7/15/2001). Fire to the ARC and the Wildland Urban 

Interface are a greater concern for an area such as Custer with a high portion of private 

lands and large portion of that private being forested.

Custer Community Wildfire Protection Plan (CWPP) 

The Custer County CWPP identified the City of Custer ARC as an urban interface 

environment with a high density of structures and infrastructure. In many areas the 

structures lack defensible fire protection space. No formally identified Municipal 

Watersheds are located in the project area; however the community of Custer obtains its 

water from ground water within the project area. This water source is at high risk of fire 

impacts. Also there is a high potential for economic loss, and likelihood for loss of 

housing and businesses in the event of a wildfire. The Custer County CWPP identifies a 

three mile radius from the city limits of the City of Custer as a Community at Risk 

boundary, which is the intended Wildland Urban Interface (WUI) area. Approximately 

62% (15,845 acres) of the Vestal project area is within the 3 mile WUI.

Condition Class and Fire Regime

Historically, fires were more frequent and less severe. Fire suppression activities have 

trended the forest outside historic ranges. Currently, there are three general types of fire 

regimes in the Black Hills; Frequent low-severity, Infrequent high severity, and Mixed 

severity (USDA Forest Service 2005a). Fire regimes characterize the role fire plays in an 

ecosystem. The Fire Regime Condition Class rating can be used to describe the degree of 

departure from the historic fire regime (Hann et al. 2003). 

The coarse scale national data characterizes the Black Hills as primarily fire regime 

Condition Class 3, which denotes a high degree of departure from the historic fire regime. 

There is a high relative risk of significantly altering or losing key components of the 

ponderosa pine forest system. (USDA Forest Service 2005a) These conditions 

significantly increase the probability of a surface fire transitioning to a crown fire with 

increased burn severity and tree mortality. Evidence of past fires shows the potential for 

large, high intensity surface fires, and, given the right conditions, stand-replacing fires. 

Recent examples of past large fires include the Jasper, Elk Mountain II, Battle Creek, 

Rico and Alabaugh. 

Fire Risk

Risks are defined as those uses or human activities which have the potential to result in a 

wildfire ignition. Fire history occurrence of both large and point fires were analyzed 

using the project perimeter. The fire history data includes fires occurring from 1950 to 

present. Of the fires identified, 128 are known lightning-caused, 18 equipment-caused, 15 

campfire-caused, 3 smoking-caused, 38 debris burning-caused, 3 railroad-caused, 5 

arson-caused, 14 children-caused and 67 miscellaneous. Both fire history occurrence data 

as well as large fire history, those fires exceeding 20 acres, in and around the project area 

are depicted. In addition, the percent of the project area impacted was analyzed. (Figure 

8, Table 39)

Figure 8. Fire History in and around the Project Area and the Point Fire History within the 

Project Boundary.

The 14,518 acre Cicero Peak fire burned approximately 72 acres within the project area 

(<1% of total fire). 

The number of fires on the entire Black Hills National Forest system lands has remained 

fairly constant at 65-130 starts per year. The number of fires that have escaped initial 

attack has also remained constant. However, these escaped fires have become larger and 

are more difficult to control with an average large fire size increasing from under 1000 

acres per fire in the early 1900’s to over 8000 acres in recent years, having burned over 

250,000 acres since 1980. 

Values at Risk

Values are defined in the Forest Plan EIS (Appendix E-80) as any or all natural resource 

improvements, or other values that may be jeopardized if a fire occurs. There is one AtRisk Community (ARC), the City of Custer, located within the Vestal project and three 

ARC located within six miles of the project boundary. Based on the Custer and 

Pennington County data , it was determined there were approximately 3,194 structures 
Vestal Final Environmental Impact Statement Chapter 3

111

within the project area, and an additional 1,439 more within a three mile radius of the 

project area.

Figure 9. At-Risk Communities (ARC) with 3 Mile WUI, and Structures Located within 

the Project Area.

Many of these structures are homes; others represent businesses, government buildings or 

other community services. Additional values at risk include commercial timber stands, 

power lines, range improvements, such as fences and spring developments, investments 

in timber stand improvement and reforestation, wildlife habitat, including snags, forage, 

riparian areas, security cover, and mid to late seral ponderosa pine stands, sensitive plants 

and animals, recreation sites, as well as water, air and visual quality.

Fire Hazard

Fire hazard is defined as a fuel complex that determines the ease of ignition and the 

resistance to control. Hazard is an expression of what kind of fire may potentially occur 

and how it affects human values. The fire hazard rating increases as the amount and 
Vestal Final Environmental Impact Statement Chapter 3

112

continuity of surface and canopy fuels increases. As the amount of fuel on a given 

landscape increases and fuel profiles become more horizontally and vertically 

continuous, the intensity of a wildfire in that landscape is expected to increase. Areas 

with high fire hazard rating have the potential to exhibit more extreme fire behavior with 

more severe effects than those with a low hazard rating. 

Fire hazard rating is accomplished by reviewing known data regarding the arrangement

of the vegetation, or structural stage. The structural stage gives an indication of the 

current fire hazard and is a stand level rating of crown fire susceptibility. Fire hazard 

specific to this project area was analyzed per BHNF Forest Plan direction (FEIS-III-349 

and associated Fire Rating guide, August 2011). Table 40 and Figure 10 provide a 

summary of current fire hazard rating in the project area. The Table presents fire hazard 

totals for both the entire project area and also within the 3 mile WUI.

*Total includes only vegetated acres. Rocks or water are not included.

A high to very high fire hazard rating currently exists in approximately 84% of the 

project area. It is suspected that much of the non-Forest Service land also follows this 

trend of high to very high fire hazard rating, however to what extent is unknown. On a 

relative comparison, high to very high fire hazard within the 3 mile WUI buffer is similar 

to that within the whole project area at approximately 86%. 

The high to very high fire hazard rating is determined on the availability of fuels to 

sustain a fire. The high fire hazard that exists in the Vestal project area is a result of the 

disruption of the historic fire regime, creating a landscape dominated by large contiguous 

stands of dense ponderosa pine with a high loading of surface and ladder fuels. In 

addition, recent pockets of tree mortality caused by MPB would increase fuel 

concentrations on the ground resulting in an overall increase of fire hazard. 

In an area such as Vestal, where high risk coincides with high hazard, the probability of 

fire with undesirable consequences is more likely. Such a fire could be very detrimental 

to many of the values existing in and around this project area.

Air Quality

Air quality within the Black Hills National Forest is addressed in the Final Environmental 

Impact Statement for the 1997 Revised Forest Plan. Overall, air quality within the Black 

Hills National Forest is very good. Air quality is better than national ambient air quality 

standards (NAAQS) for all pollutants. 

There are two recognized Class 1 Airsheds in the Black Hills area, Wind Cave and 

Badlands National Parks. Wind Cave is located adjacent to the Black Hills National 

Forest to the southeast, and Badlands is located approximately 75 miles east of the Forest. 

A solid working relationship exists between the Black Hills National Forest and the 

South Dakota Department of Environment and Natural Resources. There have been few 

if any problems identified and communicated to the Black Hills National Forest regarding 

negative impacts to air quality relating to prescribed fire activity on the Black Hills 

National Forest in the last 10 years. The only case of known impacts was a short term 

event that lasted less than two hours. 

The Environmental Protection Agency (EPA) has established National Ambient Air 

Quality Standards (NAAQS), in compliance with the Clean Air Act. EPA established 

primary standards to protect public health; and secondary standards to protect public 

welfare. 

EPA established NAAQS primary and secondary standards for six principal pollutants. 

Of these “criteria” pollutants, one, particulate matter less than 2.5 microns in size (PM2.5) 

is a primary component of smoke emissions from wildland fires including prescribed 

fires. The primary standard for PM2.5 is 15.0 micrograms/cubic meter of air (μg/m3

). 

This means that the 3-year average of the weighted annual mean concentration measured 

at established monitoring stations must not exceed this level. EPA established the 

secondary standard as equal to the primary standard.

Data from four monitoring stations in the South Dakota portion of the Black Hills are 

reported for PM2.5 on EPA’s Airtrends website (http://www.epa.gov/airtrends/). One of 

these sites meets minimum trends completeness criteria. This site is located in Jackson 

County, near Badlands National Monument, some 90 miles east of the town of Custer. 

The other three sites record data but do not meet the minimum trends completeness 

criteria. 

Between 2000 and 2009, monitoring stations in Custer, Jackson and Meade Counties in 

South Dakota showed PM2.5 concentrations at or slightly above 5 μg/m3

, based on 

seasonally-weighted annual averages. Measurements in 2001 and 2003 at the Rapid City 

monitoring station showed levels of about 8 μg/m3. No other measurements were 

recorded for that site, and no measurements after 2009 were recorded for any of the four 

sites. These measurements are well below the national average for PM2.5 concentrations, 

and are also well below the primary and secondary standards for this criteria pollutant. 

Air pollution in the form of PM10, particulate matter smaller than 10 microns diameter, 

was at one time an issue in the Rapid City area. The 1996 Forest Plan EIS notes that the 

Rapid City area had been classified as an area not attaining the NAAQS for PM10

particulates. In September 2005, the State of South Dakota, Department of Environment 

and Natural Resources, petitioned the U.S. Environmental Protection Agency (EPA) 

requesting that the Rapid City area be re-designated from unclassifiable to attainment 

status for the PM10 standard. EPA published a proposed rule in the Federal Register on 

December 9, 2005, soliciting public comment on the proposal (70FR73183). On March 

6, 2006, the EPA published a final rule approving the request from the State of South 

Dakota (71FR11162). The approval was based on the State’s demonstration that the 

Rapid City area was in attainment of the PM10 national standard, and commitment to 

continuation of fugitive dust controls. The Rapid City area was officially re-designated 

from unclassified to attainment status for PM10 effective April 5, 2006. 

The Vestal project area is in the vicinity of two Class 1 Airsheds; Badlands National Park 

and Wind Cave National Park and several communities at risk (Figure 9). The project 

area is designated as a Class II area allowing higher concentrations of pollutants than the 

Class I Airsheds. Smoke generated by wildfire is usually greater and cannot be 

mitigated; however, smoke generated under controlled conditions can be mitigated using 

the following means: 

• Limit treatment area size

• Specify wind directions and speed 

• Specify minimum mixing heights 

• Stagger ignitions 

These mitigation techniques in addition to other control methods for smoke management 

minimize the impacts of smoke to visibility and human health.

Environmental Consequences

Alternative 1

The No Action alternative assumes that no change in management would occur within 

the project area. Management actions currently being practiced, including suppression 

would continue to be practiced. The only other changes that would occur on the 
Vestal Final Environmental Impact Statement Chapter 3

115

landscape would be those that occur as a result of natural occurrences, wildfire 

suppression or those resulting from other project decisions.

Direct and Indirect Effects

The current mountain pine beetle outbreak is expected to run its course with much of the 

area expected to be heavily impacted by 2018. Changes to fire hazard within the project 

area are expected resulting in substantial areas of dead trees. Trees that die as a result of 

MPB infestation may break or fall within 1 to 3 years. 

No improvement in condition class is expected to occur with this alternative. The project 

area would continue to possess a high risk of losing key ecosystem components, resulting 

in increased fire size, intensity and severity. The MPB disturbance is not a fire 

disturbance therefore would not improve the existing fuel conditions. The arrangement 

of the fuels would change under post MPB conditions but no treatment of that vegetation

would occur. This trend would continue until a fire disturbance. 

The actions associated with this alternative are not substantial enough to significantly 

alter human activities or usage in the area therefore fire risk is not expected to change 

because the probability of an ignition occurring is not expected to change. 

According to Langowski (2006), research has shown that post-epidemic stands had 

increased rates of surface fire spread, fireline intensity and total heat release. They also 

had increased chances for crown fire initiation but decreased chances for active crown 

fire spread. Chances for crown fire initiation were also greater due to larger amounts of 

dead aerial fuels in the overstory. Observations and theoretical consideration indicate 

that both fire severity and probability of crown fire may increase following outbreaks due 

to increased fuel loading and changed fuel characteristics. 

Crown fire hazard in MPB affected stands can be best described as bi-modal. Crown fire 

hazard is higher than in non-MPB affected stands during the 2-3 years post-epidemic 

while most of the dead needles are retained on the killed trees and again following snag 

fall and stand-re-initiation when surface fire spread and intensity would be higher than in 

non-MPB affected stands due to increased surface fuel loads.

Qualitatively, in the absence of treatments or the use of prescribed fire, the fire hazard is 

expected to worsen across the project area. The only action that could improve the fire 

hazard, in this alternative, is a wildfire and the longevity and improvement of that 

wildfire would be directly associated to the fire intensity. 

Fire behavior in both the moderate and high severity areas would result in an increase in 

resistance to control and a greater likelihood of wildfire escape leading to an increased 

risk of loss of natural forest resources as well as private property, and decreased 

firefighter and public safety. The high intensity would also cause consumption of the 

remaining duff layer and soil heating as well as other resource damage. Without

treatment, the fire hazard would continue to move toward very high. The greatest 

potential for wildland fire growth and severity exists with this alternative. For a 

comparison of fire hazard by alternative please refer to Figure 15. 

The No Action alternative would not reduce fire hazard in the WUI or within the project 

area. It would actually increase fire hazard with approximately 91 percent of the WUI in 

a high to very high fire hazard. This alternative would move away from objective 10-01. 

No fuel reduction treatments would occur within this project area. The substantial values 

would not be protected by reducing hazard or risk. This alternative would move away 

from objective 10-04. 

Air Quality

Although air quality would not be directly impacted under the No Action alternative, 

there would not be any control over the timing or amount of emissions released into 

adjacent airsheds in the event of a wildfire. A large wildfire has the potential to make a 

much greater impact on adjacent communities and Type 1 airsheds, possibly exceeding 

National Air Quality Standards. The EPA addresses smoke from wildland fire under 

their natural events policy at http://www.epa.gov/ttn/caaa/t1/memoranda/nepol.pdf. 

(USDA Forest Service 2005a) 

Very few of the natural fuel breaks and past harvest units within the analysis area are 

large enough to moderate a rapidly spreading high intensity fire. (USDA Forest Service 

2008a) Therefore, it is likely that a large scale stand replacement fire would eventually 

occur within the analysis area. Due to the projected high level of surface fuel loading 

(40-60 tons/acre) these fires could be quite severe resulting in undesirable effects. Under 

the No Action alternative, the Vestal Project would not contribute to the need to protect 

local communities and watersheds from large-scale, high intensity wildfire.

Alternative 2

Alternative 2 focuses on the management of vegetation to maintain and improve forest 

health and reduce the risk of large-scale, high intensity wildfire.

Direct and Indirect Effects

Alternative 2 would decrease the potential for large scale, high intensity fires, allowing 

for characteristic low to mixed severity fires to occur. This alternative also would have a 

significant effect on fire behavior. The chances for successful initial attack under this 

alternative are much greater than No Action and the risk to residential areas, the general 

public, and firefighters is also greatly reduced. If these stands encounter fire, treated 

stands generally burn in a surface fire configuration with isolated and small group 

torching. In addition, an improvement of FRCC can be expected as conditions move 

towards a more natural condition. 

The actions associated with this alternative are not substantial enough to significantly 

alter human activities or usage in the area therefore fire risk is not expected to change 

because the probability of an ignition occurring is not expected to change. 

Fire hazard would be greatly reduced in this alternative (see Figure 14 and Table 43). 

The mechanical treatments and prescribed burning would decrease ladder fuels, reduce 

the surface fuel loading, and break up the continuity of the fuels. Prescribed burning 
Vestal Final Environmental Impact Statement Chapter 3

118

would be used to maintain openings that were created near Buckhorn Mountain for 

mountain goat forage. These openings were created previously under a separate project. 

Prescribed burning would also enhance the mosaic of burned and unburned fuels which 

resulted from past wildfires. The result of these treatments would be a decrease in 

flamelength, intensity, duration, spotting, probability of ignition, and crownfire potential. 

This would create more strategic and tactical firefighting opportunities resulting in 

greater success during initial attack due to the fact that fireline construction rates would 

be enhanced, line placement opportunities would increase, and resistance to control 

would decrease. The reduction in fire behavior would create a safer environment for 

firefighters as well as the public. The break up in fuel continuity would also lead to more 

opportunities for locating safety zones. The risk of MPB outbreaks and the resulting 

accumulation to surface fuels would also be reduced by thinning. For a comparison by 

alternative please refer to Figure 15, on the next page.

This alternative would meet the Forest Plan Goal 10 of establishing and maintaining a 

mosaic of vegetative conditions to reduce occurrences of large-scale, high intensity fire, 

insect, and disease events, and facilitate insect and disease management and firefighting 

capabilities. The proposed action would be consistent with Objective 10-01 by reducing

fire hazard within the 3 mile WUI around the ARC of Custer. Proposed actions would 

manage for 50% - 70% moderate to low fire hazard in the wildland urban interface. In 

the short-term, directly following treatment, the percentage of WUI area with moderate 

and low fire hazard would be approximately 70 and 21 percent, respectively (see Table 

44). Stands in a moderate fire hazard would grow over time and move into a high hazard 

condition. Those in a low hazard condition would grow into moderate hazard.

The proposed action includes design criteria for slash treatments. All proposed actions, 

including mechanical treatments, prescribed fire and slash treatments would reduce 

potential fireline intensity as directed in guideline 4110. The project area has substantial 

risks, hazard and values. The proposed action would treat fuels commensurate with these 

risks, hazard and values and therefore, meets objective 10-04. 

Air Quality

During prescribed burn activities, the main pollutants that would be emitted include: 

PM2.5, PM10, carbon monoxide and volatile organic compounds. PM10 emissions may 

also be present resulting from logging operations, log hauling and road 

construction/reconstruction or rehabilitation activities.

Smoke generated from prescribed fires may affect visibility and air quality, and may be 

noticed by nearby residents, recreational users, adjacent communities and perhaps in 

sensitive areas such as the Class 1 Airsheds in Wind Cave or Badlands National Parks 

depending on transport wind direction and mixing heights. Of the six criteria air 

pollutants identified by the EPA, particulate matter with diameters less than 2.5 microns 

(PM2.5) is the pollutant of greatest concern from prescribed fire activities. Most of the 

mass of wildfire smoke (80-90%) falls into the PM2.5 classification. A 1997 amendment 

to the Clean Air Act established a national goal of prevention of any future and 

remedying of any existing impairment of visibility in mandatory Class 1 federal areas 

where impairments result from human caused pollution. 

Prescribed fire operations would result in short-term emissions to the atmosphere. Dust 

may also be generated through timber harvest activities including log hauling and road 

construction or reconstruction, adding fine particulate emissions locally. Due to the 

generally lower intensity of prescribed fire activities, fuel consumption is expected to be 

lower and overall emissions would be lower than those expected from a high intensity 

wildfire.

Any prescribed burning is subject to prescriptive elements as defined in an approved 

Prescribed Fire Plan. These prescriptive elements may include mixing height, transport 

windspeed and direction as well as the adjective smoke dispersal forecast. Monitoring of 

potential smoke impacts occurs at different levels during a prescribed burn and may 

include on-site air monitoring stations, ocular estimation of visual smoke impacts or 

referencing of air monitoring sites at Wind Cave or Badlands National Parks or the 

monitoring site in Rapid City, SD. Secondly, the prescribed burn planning process itself 

incorporates the Interagency Prescribed Fire Planning and Implementation Procedures 

Guide (July 2008) and undergoes technical review prior to Line Officer review and 

approval. Potential short-term effects would be minimized by project design criteria and 

by following applicable smoke permit conditions identified in the appropriate State 

Implementation plans. Public notification procedures prior to initiating a prescribed fire 

project would be specified in the approved burn plan. 

Pile and broadcast burning would release carbon dioxide and other compounds into the 

atmosphere. Carbon dioxide release may contribute to climate change. However, the 

potential impact at the project level scale would be negligible.
Vestal Final Environmental Impact Statement Chapter 3

121

Cumulative Effects

The cumulative effects in the Vestal project were analyzed using those activities 

occurring within the project boundary. Those effects were analyzed from 2007 thru 2018, 

which captures those treatments which have improved fire hazard in the past and allows 

for mountain pine beetle (MPB) activity, mechanical and prescribed fire activities to be 

complete. The cumulative effects would occur on all types of ownerships that fall within 

the designated area.

In the Vestal project area, past, present and reasonably foreseeable future actions as well 

as the spread of the MPB contribute to changes in fuel conditions. Past management 

activities may have created situations that could have increased as well as decreased the 

risk of large scale, high intensity wildfires. For example, wildfire suppression leads to a 

buildup in down woody material, increased stocking, and increased ladder fuels, which 

all increase fire hazard. These activities have also contributed to an increase in wildland 

fire behavior, tree densities, the presence of ladder fuels, and dense crown closures, again 

all contributing to higher fire hazard. In addition, these dense stands have also 

contributed to the growth of MPB. If fires had been allowed to burn instead of pursuing 

an aggressive fire suppression program over the last 75-100 years, a significant increase 

in the amount of acreage in stands would have burned at a more frequent interval and a 

lower intensity. However, today’s conditions favor wildfires of increased fire intensity at 

longer fire return intervals.

Management activities which have reduced fire hazard in the project area include the 

Quincy Bug and Atlantic Bug sales. Reductions in fire hazard occurred on all of the sites 

treated in these activities.

Various vegetation treatments on private lands within the WUI have contributed to 

reducing fire hazard in the WUI. Some landowners have thinned their property or 

removed dead trees. The City of Custer has accomplished some thinning and cutting of 

dead trees as well. It is expected that such treatments would continue. These actions are 

cumulative when added to fuel reduction proposed in alternative 2 and would contribute 

to reducing overall fire hazard within the WUI. The No Action alternative would 

increase fire hazard within the WUI, and within the project area as a whole, even when 

added to actions on other ownerships to reduce fire hazard. 

Vegetation treatments identified on non-Forest Service lands within the cumulative 

effects area would enhance the cumulative value of both FRCC and fire hazard, both 

within the WUI area as well as within the entire project area. In areas not being treated, 

the potential for sustained crown-fires, as well as fireline intensity would increase. With 

this type of fire behavior, forest suppression objectives would not be met. 

Fire occurring several miles outside of the project area may affect Vestal project area 

under the right conditions. On the Black Hills National Forest, fires in adjacent areas 

have previously had the ability to make large runs of up to 12 miles. Although this event 

is rare and requires extreme conditions, a large scale high intensity fire is more probable 

if no treatment is implemented. A fire start in Vestal (under the right conditions) would 

not only threaten or damage/destroy improvements within the City of Custer, but also has 

the potential to burn into or affect surrounding communities such as Keystone, Hill City, 

and Hayward within one burning period (12 hours). A large scale, high intensity wildfire 
Vestal Final Environmental Impact Statement Chapter 3

122

brings with it numerous risks and effects. Homes in the path of a wildfire are perhaps the 

most immediately recognized value at risk, however, severe wildfires put the numerous 

other important values at risk including: critical infrastructure, critical fish and wildlife 

habitat, firefighter and public health and safety, soil productivity, clean air, and functional 

fire-adapted ecosystems (Graham et al. 2004). Some of these values are also threatened 

by the secondary effects of wildfire, such as landslides, soil erosion, and the spread of 

exotic species (Graham et al. 2004).

The proposed action alternative is expected to have positive long term cumulative effects. 

The proposed treatment combined with foreseeable future projects, including anticipated 

fuel reductions on non-Forest Service lands, would decrease the potential for large-scale, 

high intensity wildfire as well as decrease fuel loading moving the project area to a more 

desirable condition. The proposed treatments would reduce stand density and canopy 

closure bringing the forest back to a more historical type condition. These treatments on 

private lands combined with the treatments proposed in Vestal would decrease the 

hazardous fuels much more efficiently for longer periods of time. 

Air Quality

The smoke and other emissions that may be generated by activities planned under the 

selected alternative may contribute to local and regional pollutant loading. The 

cumulative effect of prescribed fire activities or other planned land management activities 

would be short-lived and once smoke and/or dust has dissipated, the impact is over and 

would have no further overlap in time or space with other pollutants that are generated by 

non-Forest Service activities. As a result, planned land management activities (including 

prescribed fire) are not expected to have long term or significant impacts to National 

Ambient Air Quality Standards throughout all alternatives and should not contribute to 

significant future impairments of visibility in Class 1 Airsheds. 

Approved prescribed burn plans use design criteria approved in NEPA project decisions. 

These design criteria have proven effective over the last ten years in maintaining smoke 

emissions at acceptable levels, as demonstrated by State monitoring which has shown 

only one temporary violation of PM2.5 standards at the monitoring site in Rapid City that 

may have resulted from prescribed fire activity on the Black Hills National Forest. The 

Forest Service believes these design criteria have been shown to be effective and the 

same criteria can be expected to be effective under the selected alternative for this 

project.

Botany, Rangeland, and Noxious Weeds

Affected Environment

Botany

A comprehensive botanical survey was completed in 2006 exclusively for the Vestal 

project area to collect information related to plant communities, identify rare plant 

species habitat, and locate rare species. The term “rare” will be used to describe species 

uncommon in the Black Hills, the State of South Dakota, or the Rocky Mountain Region. 

These species include plant species listed on the Regional Forester’s sensitive list (see 

Vestal Botany Biological Assessment and Evaluation), Black Hills National Forest 
Vestal Final Environmental Impact Statement Chapter 3

123

Species of Local Concern (SOLC), species having insufficient information to make 

listing determinations, as well as species tracked by the South Dakota Natural Heritage 

Program. Subsequent surveys were completed in 2010 and 2011 as a result of long-term 

rangeland monitoring for the livestock grazing program and general plant surveys of the 

area. Surveys would be ongoing in the project area. 

Rare plant species habitats include; riparian areas, moist spruce forests, hardwood forests, 

granite outcrops, grasslands and meadows, open areas. The project area includes all of 

these types of habitats.

South Dakota State Listed Plant Species and Species of Insufficient Information: 

Forest Service Manual 2670.32 directs us to “Assist states in achieving their goals for 

conservation of endemic species”. These species are tracked by the South Dakota Natural 

Heritage Program and have been identified as rare or lack sufficient information in the 

State of South Dakota. The following tracked species are known to occur in the project 

area as a result of plant surveys.

Species of Local Concern (SOLC) 

There are no known occurrences of SOLC within the project area; however, suitable 

habitat is present in the project area for 4 species. Suitable habitat for species not known 

to occur within the project area was based upon general habitat characteristics, proximity 

to known populations, and professional judgment. The project area contains a significant 

amount of habitat that was altered during post-settlement times (e.g. mining, hay fields, 

homesteads, etc.). Species of Local Concern plants which may have habitat in the project 

area include:

• leathery grapefern (Botrychium multifidum)

• southwestern showy sedge (Carex bella) 

• alpine mountainsorrel (Oxyria digyna)

• arrowleaf sweet coltsfoot (Petasites frigidus var. sagittatus)

Region 2 (R2) Sensitive Species 

A pre-field review was conducted of available information to assemble occurrence 

records, describe habitat needs and ecological requirements, and determine whether field 

reconnaissance is needed to complete the analysis. Sources of information included 
Vestal Final Environmental Impact Statement Chapter 3

124

botanical surveys, Forest Service records and files, local professional judgment, and 

published research. Viola selkirkii is the only known R2 Sensitive Plant Species that 

occurs within the project area. Suitable habitat is however present in the area for two 

other species. Suitable habitat for species not known to occur within the project area was 

based upon general habitat characteristics, proximity to known populations, and 

professional judgment. 

R2 Sensitive Species known to occur in the project area: 

• great-spurred violet (Viola selkirkii ) 

R2 Sensitive Species with habitat in the project area: 

• yellow lady’s slipper (Cypripedium parviflorum) 

• large round-leaf orchid (Platanthera orbiculata)

Range

There are currently a total of 13 grazing permits, (2 private land permits, and 11 term 

permits) within the analysis area. Cattle are present in the following allotments from 

June 1st – October 10th. There are numerous structural range improvements on federal 

land within the analysis area, including allotment boundary fences, unit division fences 

and water developments. 

Ponderosa pine encroachment in grassland/meadow areas is problematic in the area. As 

well, numerous areas that had been probable open pine savanna sites now have mostly 

closed canopies leading to reduced forage production. 

Noxious Weeds

There are approximately 1,000 acres of identified noxious weed infestation in the project 

area. Nearly half of this acreage includes Canada thistle, although sixteen different 

weeds species have been identified. 

Previous noxious weed treatments in the Vestal project area includes 111 acres adjacent 

landowners program funded by Custer County RAC, approximately 45 acres of treatment 

of known leafy spurge, dalmatian toadflax, spotted knapweed, and yellow toadflax 

locations. Releases of biological controls to target Canada thistle, common mullein and 

leafy spurge have occurred within and adjacent to the project’s boundary. The majority of 

the perimeter of the Vestal project has been treated in the past five years in association 

with previous timber sales.

Environmental Consequences

Alternative 1

There would be no direct effects to any known or unknown rare plants, noxious weeds or 

range resource since no activities would occur. 

Botany

Hardwood stands provide suitable habitat for; southwestern showy sedge, arrowleaf 

sweet coltsfoot, sweetgrass, least grapefern, musk-root, pale moonwort, bristly muhly, 
Vestal Final Environmental Impact Statement Chapter 3

125

and Michigan moonwort. Hardwood stands are expected to temporarily benefit from the 

projected mountain pine beetle-caused mortality as competition for sunlight and nutrients 

is reduced. However, continued encroachment of the smaller diameter ponderosa pine 

within the hardwood stands would occur. These trees would mature and eventually shade 

out the hardwoods. In addition, increased fire hazard poses a risk for a high intensity fire 

with the potential of being stand-replacing in the hardwood communities, which may 

have a detrimental impact on rare plants and their preferred habitat.

White spruce stands typically contain suitable habitat for: southwestern showy sedge, 

alpine mountainsorrel, arrowleaf sweet coltsfoot, leathery grapefern, least grapefern, pale 

moonwort, musk-root, pale moonwort, bristly muhly, and Michigan moonwort. White 

spruce stands would likely benefit in the short-term somewhat from the mountain pine 

beetle infestation as ponderosa pine within these stands are killed by the beetle. This 

would reduce competition for available nutrients and sunlight. 

Although, like many rare plants, effects of fire on leathery grapefern is not well known, 

range-wide it is often found associated with fire-adapted species (Anderson 2005). 

Anderson also notes that disturbance (such as fire) may play a role in the reproductive 

biology of leathery grapefern. The Forest Plan Phase II Amendment determined leathery 

grapefern is likely to persist on the forest (USDA Forest Service 2005a). This project is 

consistent with the Forest Plan for this species and its habitat. 

Southwestern showy sedge is reported to be fire tolerant (Glisson 2003) and in the project 

area it is found in a moist habitat that would not burn readily under prescription. It is 

uncertain if the shaded conditions at known sites are a habitat requirement, however, if it 

is, the species may be affected by a large-scale wildfire by loss of shade-providing white 

spruce (USDA Forest Service 2005). The Forest Plan Phase II Amendment determined 

southwestern showy sedge is likely to persist on the forest (USDA Forest Service 2005a). 

This project is consistent with the Forest Plan for this species and its habitat. 

There are no known occurrences of alpine mountainsorrel in the project area. The habitat 

that it generally occupies is generally moist and cool and would not readily burn under 

prescription. The Forest Plan Phase II Amendment determined alpine mountainsorrel is 

likely to persist on the forest (USDA Forest Service 2005a). This project is consistent 

with the Forest Plan for this species and its habitat. 

The potential for high intensity fire would increase with mountain pine beetle-caused 

mortality in the surrounding ponderosa pine. High intensity fires have the potential of 

being stand-replacing in the white spruce communities, which may have a detrimental 

impact on plants and their preferred habitat. 

Riparian areas, grasslands and meadows provide habitat for; alpine mountainsorrel, 

arrowleaf sweet coltsfoot, leathery grapefern, least grapefern, pale moonwort, musk-root, 

pale moonwort, bristly muhly, silvery sedge, swollen sedge, sweetgrass, bristly muhly, 

woolgrass, northern bog aster, and Michigan moonwort. With the projected mountain 

pine beetle caused-mortality, these areas are expected to temporarily benefit with the 

removal of the overstory. However, the loss of shade-providing large trees may alter the 

micro-climate of some areas and result in loss of plant habitat. The increased potential 

for large-scale fire in the area presents a risk to riparian habitats, as well as grasslands 

and meadows. Under such conditions, the moist forested sites and riparian areas that do 
Vestal Final Environmental Impact Statement Chapter 3

126

not generally burn could ignite and burn at unusually high temperatures. This could 

result in a loss or degradation of plant habitat. This type of fire oftentimes has effects 

such as deep soil heating and intensities that could also negatively affect suitable habitat. 

Another effect of this alternative could be the eventual decrease of graminoid dominated 

communities in the area as forested stands become denser and ponderosa pine continues 

to encroach upon meadow areas. Pine encroachment into these habitats would continue 

and may result in a loss of habitat for these species.

Noxious weed infestations are a risk for all rare plants, as exotics are often able to outcompete native vegetation for available nutrients. The lack of additional disturbance 

associated with the No Action alternative would reduce the possibility of noxious weed 

infestations in the rare plant habitat. The potential for fire disturbance could impact 

weeds as discussed below. 

The effects to R2 Sensitive Species are discussed in detail in the Vestal Biological 

Assessment/Biological Evaluation. In summary, all alternatives have a determination of 

“May adversely impact individuals, but not likely to result in a loss of viability in the 

Planning Area, nor cause a trend for federal listing.” for the three species which occur 

or may occur in the Vestal project area.

There would be no direct effects to the 3, R2 sensitive plants which occur or which have 

habitat within the project area; Viola selkirkii, Cypripedium parviflorum and Platanthera 

orbiculata. There would be no damage to any unknown individuals from hazardous fuels 

treatments, forestry treatments, or prescribed fire.

The possible indirect effect of Alternative 1 is the increase in the potential for large-scale 

fire in the area as the number of dead and stressed trees increase. By not treating stands 

infested with mountain pine beetle and reducing hazardous fuels, there would likely be an 

increased risk for a large-scale, high intensity wildfire. Under such conditions, the moist 

forested sites and riparian areas that do not generally burn could ignite and burn at 

unusually high temperatures. This could result in a loss of sensitive plant habitat and 

Viola selkirki, Cypripedium parviflorum and Platanthera orbiculata individuals. This 

type of fire oftentimes has effects such as deep soil heating and intensities that could also 

negatively affect suitable habitat.

The lack of additional disturbance associated with the No Action Alternative would 

reduce the possibility of noxious weed infestations in the rare plant habitat. Noxious 

weed infestations are a risk for all rare plants, as exotics are often able to out-compete 

native vegetation for available nutrients and moisture. In addition, the treatment of such 

infestations with herbicides might present a risk to rare plants if unknown occurrences are 

inadvertently sprayed. 

Range

This alternative would eventually decrease grassland communities/ forage production, 

and limit grazing access. As forested ponderosa pine stands become denser and continue 

to encroach upon grassland and meadow areas, the amount of available sunlight that will 

reach the forest floor would decrease, thus decreasing grassland communities and the 

amount of available forage. In addition, as these stands become denser and dead 

mountain pine beetle infested trees fall to the forest floor, access through these stands 

would decrease, which would also decrease the amount of available forage. Decreasing 
Vestal Final Environmental Impact Statement Chapter 3

127

the amount of available forage for livestock and wildlife, may result in an increased level 

of use in those areas that remain accessible. With all of the above, this could make it 

more difficult to meet the Forest Plan Guideline 2505 with the current grazing permits. 

Noxious Weeds

Noxious weed populations would be limited to current infestations unless disturbance 

occurs from natural events, such as large-scale fire. 

Noxious weed infestations are known to increase with large fire events. The lack of 

treatment of hazardous fuels would lead to the potential increase of a large-scale high 

intensity wildfire, thus increasing the potential for a large-scale outbreak of noxious 

weeds. Mature stands of timber are common in the project area and comprise large 

contiguous areas of forest that are similar in structure. This provides the potential for 

wildfire and beetle infestation, both of which could play a role in the spread of noxious 

weeds. An increase in dead and down trees resulting from beetle kill could increase the 

potential for wildfires to spread and burn with increased intensity. This would lead to 

large areas of bare ground on which weeds could become established and compete with 

more desirable species. As trees mature and canopy cover and needle cast increases, 

existing grass/forb communities may decrease in health and vigor as light needed for 

photosynthesis is reduced. This hampers the ability of these communities to recover from 

intense fires. When the canopy cover is opened up due to wildfire or MPB kill, 

grass/forb communities may not be able to out-compete noxious weeds in areas where 

infestations already exist. As a result, these infestations are likely to increase.

Alternative 2

Botany

Rare plant species with suitable habitat occur in similar habitats throughout the project 

area. These habitats are generally areas that receive additional moisture (riparian areas, 

drip lines around rock outcrops, etc.), aspen and/or paper birch stands, or have suitable 

habitat in cool air spruce drainages. The exception to this would be some Botrychium

species that often have a variety of preferred habitat (open meadows, old roadbeds/trails, 

skid trails, etc.) that typically have had some level of disturbance. All species will be 

analyzed by habitat type in the effects analysis below.

Impacts to the rare plant species may be direct impacts (i.e. trampling, mechanical 

damage, etc.), or the impacts may be more indirect such as a change in the microclimate 

from treatments, which may result in a loss of habitat. It is unlikely there would be direct 

effects from mechanical treatments to habitat located in granite outcrops (inaccessible by 

equipment and would unlikely burn), spruce forests (protected by design criteria), or 

riparian areas (protected by design criteria and unlikely to burn intensively). Rare plant 

habitat in granite outcrops, riparian areas, and hardwood stands are expected to benefit 

indirectly from the treatments proposed in Alternative 2 due to the reduction in potential 

for large-scale fire. 

Hardwood (aspen, paper birch) stands are expected to benefit from the proposed 

treatments in this alternative. There are 557 acres of proposed hardwood treatments 

(Hardwood Conversion, Hardwood Release) and likely many acres of hardwood 

inclusions within ponderosa pine stands. Treatment of hardwood stands would remove 
Vestal Final Environmental Impact Statement Chapter 3

128

and/or kill conifer species that have degraded these stands. This would have a long-term 

positive impact on this habitat type. However, short-term negative effects are expected 

from the proposed treatments. Theses impacts include a possible temporary loss of 

habitat from the disturbances associated with the treatments. Negative impacts may 

include increased noxious weed infestations, soil disturbance, trampling of known and/or 

unknown plants, or any other changes in the microclimate.

If hardwood stands are treated with prescribe fire this would likely have positive impacts 

by increasing vegetation diversity, recycling nutrients, and reducing the likelihood of a 

high-intensity wildfire. With prescribed fire treatments, the risk of damage to rare plants 

is typically minimal as hardwood stands, burned under prescription, generally do not burn 

intensively. Most rare plants are normally dormant during times of prescribed fire 

implementation. Rare plant species that have suitable habitat in hardwood stands include, 

but are not limited to: southwestern showy sedge, arrowleaf sweet coltsfoot, sweetgrass, 

least grapefern, musk-root, pale moonwort, bristly muhly, and Michigan moonwort. 

White spruce would have effects to this habitat type from the proposed activities. This 

alternative proposes to reduce the likelihood and the intensity of a large-scale fire that 

would negatively impact this habitat. Rare plant species that have suitable habitat in 

spruce stands include, but are not limited to: southwestern showy sedge, alpine 

mountainsorrel, arrowleaf sweet coltsfoot, leathery grapefern, least grapefern, pale 

moonwort, musk-root, pale moonwort, bristly muhly, and Michigan moonwort. 

Riparian areas, grasslands and meadows would benefit more than in Alternative 1. This 

alternative would remove all conifers from existing meadows and grasslands. With the 

projected mountain pine beetle caused-mortality and the proposed treatments, these areas 

are expected to benefit with the removal of the ponderosa pine that is encroaching into 

this habitat. Conifer encroachment into these areas alters the habitat and long-term 

reduces the quality for rare plant species that are dependent upon this type of habitat. 

However, the loss of shade-providing large trees may alter the micro-climate of some 

areas and result in loss of plant habitat. Riparian areas would receive protection with 

application of the watershed design criteria “All applicable Best Management Practices 

(BMPs) and R2 Watershed Conservation Practices (WCPs) will be implemented” 

Overall riparian vegetation is expected to benefit from the removal of ponderosa pine on 

adjacent sites as more moisture becomes available in treated areas. Most potential for 

direct effects from the implementation of this alternative in riparian areas would come 

from prescribed fire. Rare species that have suitable habitat in riparian, meadow and 

grasslands include, but are not limited to: alpine mountainsorrel, arrowleaf sweet 

coltsfoot, leathery grapefern, least grapefern, pale moonwort, musk-root, pale moonwort, 

bristly muhly, silvery sedge, swollen sedge, sweetgrass, bristly muhly, woolgrass, 

northern bog aster, and Michigan moonwort. 

Although specific data is lacking on the Black Hills National Forest, the earlier 

successional conditions that occur with opening the overstory canopy could produce 

conditions that would be beneficial to site colonization by wind-dispersed, sporeproducing Botrychium species if the associated mycorrhizal species and other microsite 

conditions are present (Farrar 2004). 

Prescribed burning within the project area would help prevent a high intensity wildfire 

that may occur due to the large amount of mountain pine beetle-caused mortality. While 
Vestal Final Environmental Impact Statement Chapter 3

129

effects of prescribed burning are not well known for most rare plants (USDA Forest 

Service 2005a) it is presumed that a large-scale wildfire would be more detrimental to 

individuals and their habitat than would fire burned under specific prescription. There is 

always a possibility of noxious weed infestation when an area burns, but again, effects 

are considered to be lessened when an area is burned under prescription rather than 

wildfire. There are design criteria in place that would require the involvement of the 

district botanist when developing burn plans so that the habitat requirements of rare 

plants in the area would be considered. 

Indirect effects from any of the proposed treatments would be the increased potential for 

noxious weed infestations in disturbed areas. This can be detrimental to rare plant 

species, as noxious weeds and invasive species have the ability to out-compete desired 

native and rare plant species. The herbicides used in noxious weed control can also be 

detrimental to rare species if the individuals are inadvertently exposed to the herbicides. 

While unknown individuals may exist on these sites and may be damaged during 

operations, the overall effect should be neutral to beneficial. 

The effects to R2 Sensitive Species are discussed in detail in the Vestal Biological 

Assessment/Biological Evaluation. In summary, all alternatives have a determination of 

“May adversely impact individuals, but not likely to result in a loss of viability in the 

Planning Area, nor cause a trend for federal listing.” for the three species which occur 

or may occur in the Vestal project area.

There is currently one known location of Viola selkirkii within the project area that may 

be impacted by the treatments. There is a potential for other suitable habitat that contains 

unknown individuals. This known location is however surrounded by rock outcrops and 

is located in a highly inaccessible area. Prescribed fire is proposed in a known occurrence 

of Viola selkirkii. 

It is believed that applying prescribed fire within the project area would help prevent a 

high intensity wildfire that may occur due to the large amount of mountain pine beetlecaused mortality. It may also increase the water and nutrients available to Viola selkirkii,

Cypripedium parviflorum and Platanthera orbiculata habitat, thus enhancing the habitat. 

There is always a possibility of noxious weed infestation when an area burns, but again, 

effects are considered to be lessened when an area is burned under prescription rather 

than wildfire. Because Viola selkirkii, Cypripedium parviflorum and Platanthera 

orbiculata habitat occurs in Picea glauca stands and it is often protected by large granite 

outcrops, it is unlikely the area would carry a fire when burned under prescription. 

However these areas may burn in a large-scale wildfire that is likely to have much more 

severe conditions. In addition, there is design criteria in place that would require the 

involvement of the district botanist when developing burn plans so that the habitat 

requirements of Viola selkirkii would be considered, including the exclusion of small 

areas.

The known occurrence of Viola selkirkii would be protected from any mechanized 

treatment activities under the design criteria for riparian and wetlands. Suitable habitat 

for Viola selkirkii, Cypripedium parviflorum, and Platanthera orbiculata is typically 

avoided by equipment conducting treatment activities due to topography (rock outcrops, 

etc.) and riparian areas. Riparian areas would receive protection with application of the 

watershed design criteria “All applicable Best Management Practices (BMPs) and R2 
Vestal Final Environmental Impact Statement Chapter 3

130

Watershed Conservation Practices (WCPs) will be implemented”. Overall riparian

vegetation is expected to benefit from the removal of ponderosa pine on adjacent sites as 

more moisture becomes available in treated areas. Considering all the above, any 

unknown occurrence will be protected through design criteria and should not have any 

negative effects from the proposed treatments. 

 

Indirect effects from any of the proposed treatments would be the increased potential for 

noxious weed infestations in disturbed areas. This can be detrimental to sensitive plant 

species, as noxious weeds and invasive species have the ability to out-compete desired 

native and sensitive plant species. The herbicides used in noxious weed control can also 

be detrimental to sensitive species if the individuals are inadvertently exposed to the 

herbicides. While unknown individuals may exist on these sites and may be damaged 

during operations, the overall effect should be neutral to beneficial. 

 

In addition to the effects as discussed above, there is the potential for additional, thus-far 

undiscovered occurrences of Viola selkirkii, Cypripedium parviflorum and Platanthera 

orbiculata in the project area. Viola selkirkii habitat (Picea glauca alluvial areas and 

granite outcrops) and Cypripedium parviflorum and Platanthera orbiculata habitat is 

expected to benefit indirectly from the treatments proposed in Alternative 2 due to the 

reduction in potential for large-scale fire and the possible increase in water available due 

to the removal of Pinus ponderosa. It is unlikely there would be direct effects to 

unknown occurrences and Viola selkirkii, Cypripedium parviflorum and Platanthera 

orbiculata habitat in Alternative 2. 

Suitable habitat, such as aspen and spruce stands, would receive beneficial treatments by 

removing conifer encroachment (long-term positive impact). However, short-term 

impacts associated with the disturbance may arise. This alternative would be consistent 

with Objective 221 

With the proposed treatments, this alternative would move reduce fire hazard and would 

be consistent with Objective 234. 

Range

Ponderosa pine encroachment in grassland/meadow areas is problematic in the area. As 

well, numerous areas that had been probable open pine savanna sites now have mostly 

closed canopies leading to reduced forage production. This alternative would increase 

the overall amount of forage available by decreasing ponderosa pine density in the 

grasslands/meadows, uplands, and aspen stands. Decreasing pine density may also open 

areas up that were previously inaccessible to livestock. The treatments may allow for 

more even distribution of livestock throughout the pastures and reduce utilization in more 

critical areas such as meadows and grasslands. Design criteria are in place to protect 

rangeland improvements. However, conflict with permitted uses may occur if water 

system components are damaged, fences are left down or gates are left open.

With the proposed treatments for removing conifer encroachment, this alternative would 

move towards Objectives 301 and 302. 
Vestal Final Environmental Impact Statement Chapter 3

131

Noxious Weeds

Noxious weed infestations are expected to increase under this alternative, in the short 

term. Commercial and non-commercial timber harvest activities and prescribed fire often 

provide mechanisms for the introduction, establishment, and spread of noxious weeds. 

Anywhere there has been some form of soil disturbance, the potential for the 

establishment of noxious weeds exists. The potential for noxious weed establishment is 

even greater in disturbed areas adjacent to existing weed populations. The movement of 

equipment in and out of these areas also facilitates weed establishment. Roads and skid 

trails create a network of corridors through which seed dispersal can occur. 

There is a potential for up to 25,449 acres being disturbed from mechanical vegetation 

treatments, fuels treatments, and prescribed fire. Skid trails, landings, burn piles and 

areas where machinery is working could create conditions in favor of seedbeds for 

noxious weeds. Design criteria is included to minimize bare ground and the potential for 

spread of weeds. The actual amount of disturbance is dependent on the scope and 

amount of acres infested with mountain pine beetle, type of equipment used, and the time 

of year the disturbance occurs. 

A ten-year review of timber sales estimated that between 2.0 and 3.5 percent of the acres 

in a timber sale are likely to develop weed infestations (USDA Forest Service, 1996, 

p.III-192). For the purpose of this analysis, 3.0 percent of all treatment activities with 

the exception of acres of prescribed fire were used to estimate the acres of infestation that 

are likely to result from harvest activities. New road construction and reconstruction 

would result in approximately 0.12 acres of new weed infestation per mile of road 

(USDA Forest Service, 1996 p. III-194). Based on this analysis, Alternative 2 may lead 

to approximately 800 acres of new infestation, in the short term (1 year following 

disturbance). However, treatment of noxious weeds would continue and the total acres 

of infestation would be expected to decrease below current levels within 4-5 years, if 

weed treatments are fully funded each year. 

Additional acres may be infested by noxious weeds as a result of prescribed fire 

activities. Dozer line, hand lines, staging areas, and areas burned so that mineral soil is 

exposed are susceptible to weed infestation. At this time, there is no formula to estimate 

how many acres of infestation might result from such activities. A number of variables 

including soil temperature, fire intensity, and time of year can influence the effect that 

prescribed fire can have on noxious weeds. While beneficial to forest health, fire can 

also be conducive to the spread of noxious weeds. Broadcast burning is proposed to be 

low-intensity, but there would probably be pockets of higher intensity fire that could 

result in exposure of mineral soil and loss of understory herbaceous species. At highest 

risk would be areas containing larger fuel loads and downed timber which create a place 

for past seed accumulation and would burn with much higher intensities. The loss of 

existing grasses and forbs provides an opportunity for weeds to become established. 

Many noxious weed species are very competitive and may prevent re-establishment of 

desirable grasses and forbs. Pre-treatment of weed infestations prior to prescribed fire 

implementation is included as design criteria and would reduce the risk of spread. Again, 

movement of equipment needed during fire operations can contribute to the spread of 

weeds. There is a risk of new species being introduced to the area when equipment is 

brought in from out of the local area. It should be noted that fire managers plan to use 
Vestal Final Environmental Impact Statement Chapter 3

132

existing roads and control lines wherever possible, which should considerably reduce the 

need to construct line on previously undisturbed ground. 

It is critical that the proposed post-harvest activity of using herbicides for noxious weed 

control be implemented to mitigate the spread of invasive plant species. Monitoring of 

the effectiveness of treatment, and retreatment as needed, is essential.

Funding estimates for noxious weed mitigation are based on the Knutson-Vandenburg 

cost guides. Currently, the average cost per acre to treat through conventional herbicide 

application is $194.00 per acre. Monitoring would be required as well, at a cost of $10 

per acre. 

By following the design criteria associated with this alternative, noxious weeds will be 

managed. With the design criteria, this alternative would be consistent with objective 

230 and 231. 

Cumulative Effects

The cumulative impact area for this analysis is the identified project area and areas 

immediately adjacent to the project area. Activities beyond the project area have a 

diminished effect on rangeland and botany resources as well as the noxious weeds within 

the project area. Impacts and effects to vegetation resources are similar to botany, 

rangelands, and noxious weeds. Therefore, any cumulative effects are alike for all three 

resources and will be jointly analyzed. The timing limit for the cumulative effects 

analysis is estimated at 20 years, ten years prior to present and ten years in to the future, 

which allows for an adequate length of time to record vegetative changes. 

Past, present and reasonably foreseeable activities within the Vestal project area include 

timber harvest, timber thinning, limited mining, wildfire, prescribed burning, grazing, 

road construction and maintenance, noxious weed control, wildlife habitat improvement 

projects, and dispersed recreational use on both the public land and private land in the 

area. A list documenting known past and planned future activities for this area is included 

in the project record.

Any past, present or foreseeable future activity that causes soil disturbance has the 

potential to introduce and increase the rate of spread of noxious weeds and other exotic 

plants. This includes, but is not limited to: previous timber sales, fire (both planned and 

unplanned), legal and illegal off-highways vehicle use, and livestock grazing. This can be 

detrimental to rangeland resources and rare plant species, as invasive species have the 

ability to out-compete desired native plants. The herbicides used in noxious weed control 

can also be detrimental to rare plant species if the individuals are inadvertently exposed 

to the herbicides and have low tolerance levels to the specific herbicide. 

There are large weed populations on private lands adjacent to National Forest land within 

the project boundary. Conversely, there are private lands that are weed free which are 

adjacent to National Forest lands which contain weeds. The potential for seed dispersal 

between both private and Forest Service lands exists. This may lead to increased weed 

populations to both the Forest Service and/or the private landowner. Treatment of weeds 

on both National Forest and private lands is occurring and would continue. These 

treatments would be beneficial in reducing weed infestations in the project area. 
Vestal Final Environmental Impact Statement Chapter 3

133

Noxious weed infestations are expected to increase under both alternatives. Commercial 

and non-commercial timber harvest activities, on both Forest Service and on adjacent 

private lands, often provide mechanisms for the introduction, establishment, and spread 

of noxious weeds. Anywhere there has been some form of soil disturbance, the potential 

for the establishment of noxious weeds exists. The potential for noxious weed 

establishment is even greater in disturbed areas adjacent to existing weed populations. 

The movement of vehicles, equipment, and other motorized vehicles in and out of these 

areas also facilitates weed establishment. Roads create a network of corridors through 

which seed dispersal can occur.

Roads and trails would continue to be avenues for spread of noxious weeds. Off highway 

use of vehicles on roads and trails would continue to promote the spread of noxious 

weeds by providing a means of transport. Seeds can collect in wheel-wells and grills of 

off-highway vehicles and may be dispersed as they travel. In areas where bare soil is 

exposed or natural vegetation is diminished, opportunities exist for the establishment of 

new infestations. 

The grazing in the Vestal project area would continue as identified in the Allotment 

Management Plans for the grazing allotments within the project area. Under the action 

alternative, creation of transitory range would have a positive cumulative effect on those 

allotments by reducing the time livestock spend in preferred areas. Broadcast burning 

proposed under the action alternative would work against the cumulative effect of fire 

suppression by killing small trees and setting back succession, though it is expected to 

have limited effects on overstory canopy. All of the effects to rangeland resources 

presented here would be limited in intensity and duration. Any negative impacts would 

be minimal and are directly related to livestock management in the short term as they are 

impacted by treatment activities.

All of the above uses are limited in intensity and duration and therefore when combined 

with the alternatives analyzed, including the No Action alternative, do not result in 

adverse cumulative impacts to the rare plant species or their habitat, the range resource or 

noxious weeds. 

Minerals and Geologic Resources

Affected Environment

The potential for development of mineral commodities within the project area is 

moderate to high. Specifically, potential exists for development of salable mica and 

feldspar resources from numerous schist units and pegmatites, and for locatable gold in 

placer deposits. Carbonates are not widespread in the project area; consequently, cave or 

karst resources have not been identified. Invertebrate and vertebrate fossils are unlikely 

to be present within project area. 

Environmental Consequences

Direct, Indirect, and Cumulative Effects for All Alternatives

Existing transportation conditions within the project area are adequate to facilitate 

activities related to exploration and development for either salable or locatable minerals. 
Vestal Final Environmental Impact Statement Chapter 3

134

The Vestal project would not cause direct, indirect or cumulative effects to mineral 

resources under any alternative.

Lands and Special Uses

Affected Environment

There are 17,693 acres (41%) of private land within the Vestal project area. The private 

in-holdings are located within the city limits of Custer City, a significant amount of large 

residential subdivisions outside of the city limits, as well as larger parcels of raw, unsubdivided private land. Access to private land is provided through system and/or nonsystem, U-unauthorized forest roads and private “drives”. The road system is more than 

adequate for providing access to private land. In some locations there are an excess of 

roads that pose management concerns as it relates to the implementation of travel 

management policies. The excess of roads are contributing to unauthorized access or 

special uses of National Forest System (NFS) land that are not authorized under permit. 

There are numerous utility corridors within the project area both overhead and buried 

providing customers with electrical, telephone and fiber optic services.

There are 9 special use permits, 47 issued easements, and 16 acquired right-of-ways 

(ROW) within the Vestal project area.

Special Use Permits: The special use authorizations within the project area would need 

to be protected. Broken Arrow Campground operates a seasonally open campground and 

is the holder of a Horse Trail Special Use Permit. The permitted area includes the use of 

system, non-system and developed trails on National Forest System land. Additionally, 

there are buried or overhead utility lines and corridors, buried water or sewage 

transmission lines or permitted signs on NFS land.

Easements: The amount of private in-holdings within the Vestal Project area has 

required the need for access on both system and non-system roads. Many residents who 

use NFS roads to access private land would be impacted by vegetation management 

activities including, but not limited to, an increase in the use of the road by timber 

harvesting equipment, log trucks and other administrative traffic. Roads that are under 

easement or special use authorization would need to be maintained to standard to mitigate 

the increased use and traffic.

Private Parcel Access/Right-Of-Way (ROW) Acquisitions: The acquired ROWs vary 

in length from 0.1 to 0.9 miles. Several rights-of-way needs have been identified for the 

Vestal Project, but are not critical for implementation to occur. Acquiring these right-ofways would be pursued as funding and time allows. 

Environmental Consequences

Alternative 1

This alternative would not have short-term effects on the lands resource, but there is 

potential for long-term effects. Due to the increase in mountain pine beetle (MPB) 

infested trees on both public and private land, tree mortality within this planning area is 

imminent. Untreated NFS lands have an increased threat of wildfires due to higher 

stocking densities. This could pose a risk of fire spread to private property. The No 

Action Alternative would also eliminate the ability to reduce potential MPB spread onto 
Vestal Final Environmental Impact Statement Chapter 3

135

private land and subsequent tree mortality by not thinning dense timber stands on NFS 

lands. Overhead utility lines may have an increased risk of damage due to widespread 

tree mortality. Any land use proposals would continue to be considered through the 

Lands and Special Uses programs. Uses such as Small Tracts Act applications, special 

use permit applications, other utility requests, easement applications and opportunities to 

acquire right-of-ways would continue within the project area. 

Alternative 2

This alternative may have long-term effects on the lands resource. The significant 

amount of special uses and right-of-ways within the project area may conflict with access 

to private land, but can be mitigated for the action alternative, provided roads are kept 

open for access to the public. Short-term effects of proposed activities would include 

dust and noise from increased traffic during harvest operations. Increased log hauling 

traffic could impact roads that the public utilizes to access their private property. Smoke 

from prescribed burning and slash pile disposal operations may impact some adjacent 

landowners. Reduction in stand density could reduce fire intensities, should a fire start on 

forest and endanger private property. Social impacts include private landowners’ 

receptivity to more aggressive silvicultural prescriptions, deadfall mechanical fuel 

treatments and their relationship to land values. No critical needs have been identified 

for acquiring right-of-ways for implementation of the action alternative.

Cumulative Effects

The Vestal project area boundary, land exchanges within the last 15 years and special 

uses within the last 20 years were used to evaluate cumulative effects. Activities 

proposed under the action alternative would have little effect on both the current lands 

and special uses and on any foreseeable future lands and/or special uses proposals. 

Heritage Resources

Affected Environment

Prehistoric Context

The Black Hills are part of the greater culture area of the Northwestern Plains with 

human occupation of dating to 11,000 B.P. (Frison 1991). Over this vast period of 

human occupation, the ecology, subsistence patterns, technology, and the cultures of 

Black Hills inhabitants have witnessed notable changes (Frison 1991). These changes are 

grouped into phases of occupation, which are held in the archaeological record. The 

Black Hills National Forest Cultural Resources Overview identifies cultural sites that 

represent all of these prehistoric phases of occupation in the Black Hills (Rom et al. eds. 

1996). Identifiable tribal groups living within the Black Hills area during the 

Protohistoric period include the Kiowa, Crow, Arapaho, Cheyenne, and Sioux. 

Many Native Americans consider the entire Black Hills sacred land. Their belief system 

links specific locations in and around the Black Hills to star constellations (Rom et al. 

eds. 1996). These spiritually significant locations include but are not limited to: Devil’s 

Tower, Old Baldy Mountain, Hot Springs, Buffalo Gap, Reynolds Prairie, the Spearfish 

Formation “race track” that surrounds the Black Hills, and Harney Peak (Goodman 
Vestal Final Environmental Impact Statement Chapter 3

136

1992). Ceremonies are performed at these sacred locations during specific periods on the 

celestial calendar or weather events (Goodman 1992).

Historic Context 

Although influenced by Euro-American culture through the introduction of horses, guns, 

and disease as early as the 17th century, sporadic use of the Black Hills by EuroAmericans largely began in the early 1800’s and consisted mainly of fur trappers and 

traders (Sundstrom 1989). The western half of South Dakota, including the Black Hills, 

portions of southern North Dakota, and nearly the entire area of the Powder River Basin 

in Wyoming and Montana was recognized as unceded Indian Territory by the 1868 treaty 

between the United States and the Sioux and Arapaho. More intense Euro-American 

occupation in the Black Hills began shortly after gold was discovered in the Black Hills 

in 1874. It was this discovery that brought a full scale influx of Euro-American 

prospectors and miners to the Black Hills. 

Historic settlement in the Black Hills by Euro-Americans is generally auxiliary to this 

history of the mining industry. Homestead patents are common from the late 1800’s 

through the 1920’s. Industries such as the ranching and logging industry became 

common in the early 1900’s. However, much of the land was not patented and remains 

public land. During the Depression/New Deal Period (1920-1941), public works projects 

became common across the Black Hills landscape. The Civilian Conservation Corp 

(CCC) and the Works Progress Administration (WPA) organized groups of men in camps 

to construct fire lookouts, roads, trails, dams, and wells throughout the area. 

Field Surveys and Eligible Sites 

Sections of the Level III cultural resource inventory were first contracted to Niwot 

Archaeological Consultants in 2008. A Level III Heritage Resource Inventory:Vestal 

Analysis Area, Calamity Unit by Brad Noisat (BKF # R2008020300101) resulted in the 

survey of 6,332 acres. The contract inventory consisted of new survey and the evaluation 

of newly discovered sites. No monitoring or evaluation of existing cultural resources was 

performed under the contract. 

The Forest Service conducted an in-house cultural resource survey of the remaining 

5,788 acres distributed across the 26,223 acre Heritage Area of Potential Effect (APE). 

The Heritage APE is considered here as all National Forest System Lands within the 

Vestal Spring analysis area, and expanded to include some portions of Pennington 

County which originally considered for NEPA analysis, and a 100 meter buffer around 

the analysis area to encompass roads bordering or leading up to the project area and 

potential areas of federal undertaking in support of the NEPA action, such as landing 

areas for logging and staging areas for prescribed burns. Newly recorded and previously 

recorded unevaluated sites were evaluated for eligibility to the National Register of 

Historic Places. All eligible sites were monitored and evaluated for effects from all 

project alternatives.

There are 19 known cultural resources determined eligible for listing on the National 

Register of Historic Places (NRHP) within the Vestal analysis area. Additionally, six 

sites within the Vestal area remain unevaluated for listing, despite further attempts to 

evaluate their significance, and will be protected as potentially eligible for listing on the 

NRHP. Most of these sites are considered historic and range in age from 70-140 years 
Vestal Final Environmental Impact Statement Chapter 3

137

before present. They include mines, homesteads, dams, and dumps. The historic sites 

are the remnants of the rich logging, mining, and settlement history of the local area. A 

number of historic sites are the remnants of the Civilian Conservation Corps of the Great 

Depression and New Deal time periods. The prehistoric sites that are present within the 

analysis area are typically rock shelters and encampments of varied and often 

undetermined age. 

Environmental Consequences

Alternative 1

If there is no federal action, then there is no undertaking, as defined in 36 CFR Part 

800.16(y), for Section 106 of the National Historic Preservation Act (16 U.S.C. 470f). 

However, No Action may result in the destruction of cultural resources due to the 

increased fuel loading and tree mortality --both of which increase the potential for fire 

and subsequent ground disturbance and erosion. Many of the eligible sites in the Vestal

project area are eligible for listing on the NRHP due to the presence of intact subsurface 

cultural deposits or standing architectural features. As such, any processes that disturb 

the soil/sediment matrices of an archaeological site (including erosion) or increase the 

intensity and probability of catastrophic wildfire, adversely impact the site’s eligibility.

Both of these potentials exist within the Vestal project area and are perceived as an 

ongoing threat to cultural resources. 

Alternative 2

The Forest Service developed site specific recommendations for all eligible cultural 

resources to avoid adverse effects from this alternative. These recommendations were 

submitted within the Section 106 report for the Vestal project. The South Dakota SHPO 

concurs with these determinations (March 19, 2012). Furthermore, SHPO concurs with a 

finding of No Adverse Effect, provided that these cultural resources are avoided by all 

ground disturbing activities during project implementation. If during the course of any 

ground disturbance related to this project, any bones, artifacts, foundations, or other 

indications of past human occupation of the area are uncovered, all operations will cease 

within a 100-meter radius of the site location and a district archaeologist notified 

immediately. The SHPO and regional Tribal Historic Preservation Offices (THPOs) will 

be notified of the discovery and provided an opportunity to comment. Any cultural 

resources located during project implementation will be protected based on the 

recommendations of the district archaeologist and the SHPO. 

Adherence to the design criteria would result in no direct or indirect effects to cultural 

resources from Alternative 2. 

Cumulative Effects

The nature of the cultural resources and the foreseeable actions in the project area dictate 

that the cumulative effects area should match the physical site boundaries. Therefore, the 

cumulative effects area is defined as the known archaeological sites in the identified burn, 

thinning units, and access roads to and from the project area. The timing limit for the 

cumulative effects analysis is 20 years; ten years prior to present and ten years in the 

future.
Vestal Final Environmental Impact Statement Chapter 3

138

No adverse effects are expected to occur as a result of any alternative provided that the 

design criteria are followed and the site specific recommendations are implemented. 

Because there would be no direct or indirect effect to cultural resources, there will be no 

cumulative effects associated with the Vestal project.

Scenery 

Affected Environment

Existing Scenic Integrity represents the current status of a landscape. It is determined 

on the basis of visual changes that detract from the scenic quality of the area. Direct 

human alterations may be included if they have become accepted over time as positive 

landscape character values. Existing scenic integrity is the current visual state, which is 

measured in degrees of deviation from the natural appearance of the landscape character 

type. These ratings give an indication of the present level of visual quality and visual 

evidence of management activities. The frame of reference for measuring achievement of 

scenic integrity levels is the valued attributes of the existing landscape character unit 

being viewed. In natural or natural appearing character, this is limited to natural or 

natural appearing vegetative patterns, features of water and rock, and landforms. 

Apparent human alterations in the form of recreation facilities (such as Bismarck Lake

Campground & Bob Marshall Camp), open roads that (such as the Peter Norbeck Scenic 

Byway, Mickelson Trail, US, State, & County Highways) provide access for commerce, 

to homes & recreation facilities, have generally been accepted over time as part of the 

positive cultural landscape character attributes. Within the planning area, forested areas 

are predominantly populated by ponderosa pine communities, aspen and other 

hardwoods, and Spruce communities generally limited to streams and wet areas. Water 

features are limited to narrow, quiet, low-flow intermittent streams and Bismarck Lake. 

Mountain pine beetle activity has rapidly expanded in the Black Hills National Forest and 

is now at epidemic levels within the Vestal project area. Generally, the MPB killed trees 

were mostly evident from county and Forest roads. Within the past few years this 

activity has become more evident from Federal, State, County highways, recreation areas, 

Mickelson Trail, communities and private lands surrounding them. Large groups of trees 

attacked by the MPB are highly evident in this portion of the planning area. 

The northern portion of the planning area has a combination of steep slopes, rocky 

terrain, and dense conifer stands, as well as gently rolling forest areas. The vegetation in 

the area has been managed for wildlife, grazing, and timber, depending upon the location. 

Scenic Integrity Objectives (SIO) 

Scenic Integrity Objectives (SIOs) are management objectives for forest scenic resources

on National Forest lands. A High SIO means that human activities are not visually 

evident and that activities should repeat attributes of form, line color or texture found in 

the existing landscape. A Moderate SIO is where activities remain visually subordinate 

to the landscape character. The Low SIO applies to landscape which appear moderately 

altered. Within the Vestal project area, the following percentages of area apply 24% High 

SIO, 49% Moderate SIO, and 27% Low SIO. A map of SIOs in the Vestal project area, 

and Concern level 1 and 2 roads, is included in Appendix A. Refer to Map 17. 
Vestal Final Environmental Impact Statement Chapter 3

139

Mountain pine beetle caused mortality continues to alter views of the landscape within 

the project area. Management activities which have occurred in the project area generally 

meet the assigned SIOs.

Environmental Consequences

Alternative 1

No direct effects to visual quality would occur. Existing conditions and natural processes 

of trees growing and regenerating would continue. The mountain pine beetle outbreak is 

predicted to impact the entire planning area by 2018. The vegetation pattern on the 

landscape would change from densely closed with few openings, to an open landscape 

with possibly a few clumps and scattered trees. 

Within 10 years the dead trees would snap off, or fall, creating openings in the forest. In 

the foreground and middleground, the color and texture of the down trees would 

dominate the landscape. In the background, the forms of these open areas would be 

dominant in the landscape. The remaining trees would likely provide the seed source for 

new trees. Seedlings would sprout over time. Long term as the new forest grows up 

through the down trees, and the down trees decay, the new growth would help these areas 

to blend into the landscape. 

A high to very high fire hazard would occur throughout the project area. Wildfires would 

likely have the ability to rapidly spread during hot and dry conditions. When fires have a 

long residence time in one area, the concentrated heat can break down the structure of the 

soil. This damaged structure allows the soil to be easily eroded, inhibiting future plant 

growth. Areas of eroded soil and lack of plant life can be evident in the landscape, and 

can be detrimental to the scenic integrity of an area.

Alternative 2

Under this alternative, trees of all sizes would be removed. Any treatments would result 

in fewer trees across the landscape – but the risk of MPB infestation and fire to the 

remaining trees would be reduced. The treatments should enhance the large tree 

component, when present, by reducing competition for nutrients. A variety of vegetation 

structure, smaller and larger trees, increasing numbers of hardwoods, grasses and shrubs 

should result. Overall, the variety of vegetation, at the stand level, should be very 

positive from a scenery standpoint. The resulting more open forest structure should 

promote views into the forest to view large diameter trees, spring and fall color, and 

wildlife.

The variety of treatments should produce a natural appearing forest – but one that has 

fewer trees – as if fire had continued to play its natural role all along. Due to the insect 

activity and fuel treatments adjacent to private land, the current view of the forest from 

these locations would likely change from their current condition. Views of these 

treatments would be limited from Concern Level 1 or 2 roads outside the planning area, 

due to the topography surrounding the planning area. 

The SIOs achieved following treatments would vary in the short and long term. 

Immediately following implementation, management activities are generally very 

evident. Over time, as understory vegetation grows, activities become less evident. 
Vestal Final Environmental Impact Statement Chapter 3

140

Forest Plan guideline 5606 pertains to the achievement of SIOs following management 

actions. This guideline specifically notes that SIOs are to be achieved following the 

completion of a project, which includes all various aspects such as seeding, road closures, 

pile burning and rehabilitation, etc. The Vestal project includes not only vegetation 

treatments, but also prescribed burning, road closures, and other design features (refer to 

Appendix B). Alternative 2 would meet guideline 5606 to achieve SIOs within the stated 

timeframes following completion of the project. 

How well commercial treatments blend into the characteristic landscape, and meet the 

SIO, is based upon the slope, aspect, and vegetation remaining on the site. Reducing soil 

disturbance, uneven spacing of the trees remaining in the landscape, and cleaning up the 

slash (branches and tree tops left when trees are commercially removed from the forest) 

to natural levels, can result in an appearance that is in harmony with the landscape 

character, often resulting in a higher SIO being achieved. 

Commercial Thin (CT60 and CT50) - Thinning and reducing the overall density of 

ponderosa pine vegetation can lead to the amount of grasses, forbs, shrubs, and 

hardwoods increasing in the landscape. This could increase the variety of colors evident 

now, and in the future, across the landscape. Thinning trees to an even spacing can result 

in a managed, unnatural appearance. In stands where there is a mixture of tree sizes, 

including the understory, random spacing and clumps of remaining trees can help 

maintain an appearance in character with the landscape and improve the SIO rating. 

Would generally meet a Moderate to High SIO, depending on the residual large tree 

component, understory and hardwoods present.

Overstory Removals (OR) result in an open area with seedlings scattered across the 

opening. Some large trees may remain for wildlife. In the Foreground, the lack of a 

forest canopy and the seedlings across the forest floor would be the most evident. In the 

Middleground & Background the form, or shape, of the unit would be most evident in the 

winter months when snow is present on the ground, creating a strong contrast from the 

darker surrounding forest. These units have the greatest potential to appear out of scale 

and character with natural vegetative patterns. Overstory Removal treatments generally 

meet a Low SIO. A Moderate SIO can be achieved if the size of the unit does not exceed 

the natural openings by more than 10%, otherwise it would likely meet a Low SIO. 

Shelterwood Seedcut (SWSC) is an even-aged regeneration treatment which retains the 

most desirable seed trees. This treatment results in an open stand with scattered larger 

trees - approximately 30-50 commercial-sized trees per acre (basal area of 30-50 ft2/ac is 

the objective), with few to no understory trees. Due to the wide spacing and no 

understory, this treatment results in a heavily managed appearance. A Low SIO can be 

met if there are a variety of tree sizes remaining throughout the treatment unit.

Group Shelterwood (GSH) - A GSH prescription may include all phases of a 

shelterwood system such as a commercial thin, seedcut or overstory removal and includes 

POL. The overall density of these stands would be no more than 60 ft2

/acre. The final 

appearance within in each stand would likely contain a range from large open areas with 

seedlings and saplings, to thin overstory stand with limited understory. This treatment 

method generally meets a Low to Moderate SIO.
Vestal Final Environmental Impact Statement Chapter 3

141

Free Selection (FS) treatment would result in reduced tree densities while maintaining 

groups of large trees and hardwoods. This would make the color and characteristics of 

larger trees and hardwoods more visible in the landscape, particularly in the foreground. 

This treatment would reduce susceptibility of stands to MPB infestation by reducing 

overall basal area within sites, which in turn would provide the conditions that can 

enhance stand diversity. This treatment reduces overall density of the site to 80 ft2/ac 

basal areas by interspersing dense groups of trees with openings. Stand densities would 

vary from 30 - 90 ft2

/ac BA. Lower basal area would likely meet a Low SIO. Higher 

basal area, i.e. 60 BA would likely meet a Moderate SIO; while 60 BA with hardwoods 

present, and 80 BA areas would likely meet a High SIO. 

Variable Density Thinning (VDT) thinning of ponderosa pine to reduce the overall 

quantity of trees on the site to a basal area average of 60. The remaining trees would be 

varied in density (spacing) - where some areas are tightly spaced and other areas they are 

widely spaced. The variety in residual tree spacing is what makes the difference as to 

how natural these treatments appear. Due to the variety it creates, that mimic natural 

vegetative patterns, this treatment should meet a Moderate to High SIO. 

Sanitation (Sani) treatment removes trees currently infested with mountain pine beetle. 

The visual effect is totally dependent upon the amount of MPB activity present. The 

results of this treatment cannot be projected due to the unknown level of MPB activity. 

When then treatment is in an area with high level of MPB activity, a Low SIO would 

likely be achieved. When then treatment is in an area with limited level of MPB activity, 

a High SIO can be achieved.

Products Other Than Logs Thinning (POL) removes 6 to 9-inch diameter trees and 

would open up views into the Forest, as the spacing of the trees would range from 18 to 

22 feet. This treatment often leaves a moderate level of vegetation debris on the forest 

floor, reducing grasses and shrubs, and dominating Foreground views. Once the slash is 

cleaned up, this treatment should meet a Moderate SIO. In the Middleground and 

Background, large diameter trees should be more dominant in this landscape also 

resulting in a Moderate to High SIO. 

Pine Encroachment (PE) This treatment would remove all pine from meadow sites. 

Generally, there are few trees in these areas to be treated, and their removal still 

maintains a natural appearing condition, and meets a High SIO. In Foreground views, 

where there are concentrations of trees to be removed, the remaining stumps are still 

evident, lowering the scenic integrity to a Moderate level for the first 5 years.

Hardwood Conversion (HC) and Hardwood Restoration (HR) These treatments 

remove all pine from mixed conifer / hardwood stands (HC) or ‘pure’ hardwood stands 

(HR) to maintain or increase hardwoods. Pine under 9” DBH would be ‘hinged’ then left 

on the site. Hinging adds a large horizontal component that can detract from the 

landscape when being viewed in Foreground settings. Once the needles fall off the 

hinged trees, this treatment should meet a Moderate SIO when viewed in the Foreground, 

and a High SIO when viewed in the Middleground & Background. Short term (less than 

10 years) this treatment should result in a High SIO being achieved, as the treated areas 

would be filled with hardwoods that would provide additional color to the landscape 

(spring and fall).
Vestal Final Environmental Impact Statement Chapter 3

142

Precommercial Thinning (PCT) removes understory trees, on this project - less than 5-

inch in diameter, to 12’ x 12’ spacing. Precommercial thinning can result in a uniform 

appearance of the remaining forest (both in size and spacing) when only smaller trees are 

present. When precommercial thinning occurs, screening would be reduced and views 

into the forest would be increased. This reduction in the understory would further 

increase the emphasis & visibility of the larger diameter trees in the landscape. 

Understory grasses and shrubs would be more evident offering seasonal variety of light 

and color (when spring flowers are evident). When activities are completed, 

precommercial thin treatment methods generally meet a Moderate SIO, however, in this 

project where only the 5-inch and less are being treated, a High SIO should be achieved.

Dead Fall (DF) is a mechanical treatment (i.e. - lopping, chipping, crushing, piling and 

burning, mastication, etc.) of existing dead & down trees that were killed by MPB 

activity. The treatment reduces the height of the material to within 18-24 inches of the 

ground. No standing live or dead trees would be cut as part of this treatment. The 

objective of this treatment is to reduce the dead fuels within these stands, thus reducing 

the potential for a wildfire to move into the crowns. By moving the aerial slash / fuels to 

the ground, fire risk is also reduced. The existing condition of a forest of dead trees is 

not appreciated by the general public, and is perceived to have a Low Scenic Integrity. 

This treatment would not change that Scenic Integrity level, but it would help the stand 

achieve a higher level of Scenic Integrity sooner.

Fuel Break (FB) is a treatment to thin the forest adjacent to private land, or other areas, 

to reduce fire hazard. Fuel break treatment would be in narrow strips, up to 300 feet, 

along the edge of private land boundaries. Trees up to 9” dbh would be cut to a residual 

tree spacing of 24’ x 24’. Residual slash would either be piled for burning, or include 

mastication of slash rather than piling and burning. The result is a an open park-like 

setting, that normally meets a High SIO, when viewed from private land and other areas. 

Prescribed Burning – Sending fire across the landscape - within a designated boundary - 

in a controlled manner is beneficial to the Scenic resource by removing dead plant 

material and slash, while stimulating plants, shrubs & hardwoods. This new growth 

normally increases visual diversity and fall color in the landscape. Once the area is 

burned, ash and blackened tree bark are clearly evident across the landscape. Normally, 

these burn marks are no longer visible once new grasses and other vegetation grow up the 

following spring. However, there is always the potential for the fire to flare up - due to 

un-expected wind or a microsite of drier material – that can create negative visual 

impacts. Under burning can meet a range from High to Low SIO, depending upon burn 

intensity. Most burns conducted on this Forest meet a High SIO 1-2 year after the 

burning is completed and the red-colored, fire-killed, needles drop off the trees and 

would meet standard 4104. 

Cumulative Effects

The spatial boundary for analyzing cumulative effects is primarily that of the planning 

area. This identified area is the landscape that is evident in the foreground and middle 

ground from the main travel routes, with particular attention to recreation facilities, 

recreation trails, and the community of Custer (due to viewer’s stationary position or 

slower pace while moving through the landscape). 
Vestal Final Environmental Impact Statement Chapter 3

143

The time boundary for this analysis extends from 1980 (when the start of recent 

vegetation management activities took place) to 2050 [completion of management 

activities (2018), followed by 5 years for pine seedlings to become established, and 

approximately 25 years for trees to grow up and visually ‘fill’ open areas]. This time 

period includes known management activities, and activities that are planned but have yet 

to be accomplished. 

Fire suppression over the past century has played a role in the increased density of the 

vegetation on the forest. Likewise, much of the Forest was pre-commercially thinned by 

the Civilian Conservation Corp in the 1930’s and 1940s, however we do not know if that 

effort included any or all of this planning area. The construction of the Needles Highway 

(SD 89) in 1919 and the Iron Mountain Road (US 16A) in 1933 focused the public’s 

attention on this portion of the Black Hills, around the community of Custer, further 

establishing the area as a recreation destination, for its man-made and natural scenery. 

Larger wildfires have not occurred within the planning area, but are readily apparent in 

the surrounding area. 

The visual effects of the MPB activity is quite evident just north of the planning area and 

in isolated pockets throughout the planning area - due to the visibility of the red needles. 

Steep slopes, and other areas that are not able to be treated, would display the full range 

of effects and mortality from the MPB. Eventually these areas would be less evident as 

the needles fall. As the trees decay and fall, openings would be created. These openings 

would change the character from a uniform appearing landscape ‘carpeted’ with pine 

trees to a complex matrix of openings, decaying dead trees, residual pine trees, and 

expanding areas of hardwood trees.

From 2000 to 2011, commercial vegetation treatments have been conducted on a limited 

basis (as noted in the Existing Condition section). Other than the Atlantic Bug project, 

all treatments have met their assigned SIO. The Atlantic Bug project was projected to 

meet a Low or Very Low SIO due to the high level of MPB activity and tree mortality 

already in the units before any treatment activities occurred. Due to the adjacent tree 

seed source around these areas, trees should become established, and visually have an 

impact in approximately 15-25 years. Then a more natural appearance may be evident.

Vegetation management activities have occurred and are occurring on private and other 

ownership lands throughout the project area. In general, the types of vegetation 

management activities occurring on private lands are similar to those proposed in the 

Vestal project. Many landowners have concerns regarding MPB and fire hazard and are 

thinning and removing beetle infested trees. These actions when combined with 

proposed actions would have similar cumulative effects to the scenery resource. 

Transportation 

Affected Environment

The existing transportation system in the Vestal project area was inventoried in 2007 and 

2008 and reviewed in 2010. During the 2010 review additional road condition surveys 

were conducted to capture any change in road conditions. The majority of the roads are 

being maintained to the appropriate design standard according to maintenance level. 
Vestal Final Environmental Impact Statement Chapter 3

144

Global positioning systems, aerial photos, and the forest road data base were used during 

the inventory process to correct any inconsistencies in the existing GIS and tabular data.

To summarize, the transportation system within the Vestal project area is comprised of 

approximately 192 miles of existing roads. The breakdown of the existing transportation 

system is listed below in Table 46.

Environmental Consequences

Alternative 1

Under Alternative 1 there would be no effects from a proposed action. There would be no 

change in the transportation system due to a proposed action. Scheduled annual and grid 

maintenance would continue as it has in the past. Road densities would remain the same 

under this alternative.

Alternative 2

This alternative proposes to utilize the existing transportation system to accomplish 

project activities. Approximately 0.1 mile of new system road would be constructed to 

gain access to an existing system road blocked by private property. Also, approximately 
Vestal Final Environmental Impact Statement Chapter 3

145

0.6 miles of non-system road would be converted to National Forest System Road 

(NFSR) and approximately 2 miles of open system road would be closed (see Map 8 in 

Appendix A). The converted system road segment was identified as needed for current 

and future resource management access. The proposed road closures (approximately 2 

miles total) are in three separate segments and would protect wildlife values and prevent 

resource damage. 

An estimated 34 miles of road would be reconstructed which may include, but is not 

limited to, structural improvements, typically rolling dips or culverts, surface 

reconditioning or realignment. An additional 91 miles of road would require 

maintenance to complete proposed activities. 

Existing unauthorized roads that are used as temporary roads with the project would be 

closed after use as part of the timber operations. Remaining unauthorized roads not used 

for the proposed activities are already administratively closed and may be physically 

closed in the future when funds become available. 

Temporary roads may also be used to access portions of proposed treatments units. The 

intent after use for all temporary road construction is that they shall be closed or 

decommissioned during post resource management activities. Temporary roads utilize 

existing unauthorized roads or are constructed in locations approved by the Forest 

Service. 

The average road density for the Black Hills National Forest is 4.4 miles per square mile 

as shown in the Forest Plan (Phase II Amendment). The minor changes to the 

transportation system proposed in Alternative 2 do not result in an overall change to road 

density. A simple comparison of road densities for the Vestal project area is listed below 

in Table 48.

Total 125 1.8 126 1.8

Cumulative Effects

Alternative 1 – No Action

Alternative 1 would have no direct or indirect effects; therefore no cumulative effects 

would occur. 

Alternative 2

This alternative would not increase open road density for the project area. Therefore, no 

negative cumulative effects to open road density would occur. 

These activities along with the Vestal project have the potential for the following 

cumulative effects on the transportation system. 
Vestal Final Environmental Impact Statement Chapter 3

146

Annual maintenance on Maintenance Level 3 and 4 roads would have a positive effect on 

the transportation system. These routes would only require minimal maintenance to 

support timber harvest activities barring no significant or catastrophic weather events 

occur. 

Road maintenance, reconstruction, and construction within the Vestal project, combined 

with annual and grid maintenance activities, would have cumulative effects on ground 

disturbance, vegetation loss, dust/noise increases and sediment movement for short 

durations and in scattered areas within the analysis area.

Recreation 

Affected Environment

The Vestal project area provides for substantial developed and dispersed recreational 

opportunities. The city of Custer is located at the center of the project area. Many 

businesses support and benefit from the recreational opportunities that this area provides. 

Some of the non-Forest Service recreation sites located within the project boundary 

include Crazy Horse Memorial and the Mickelson Trail, as well as numerous private 

campgrounds, gift shops, restaurants, hotels and other tourist based businesses. 

Recreation Opportunity Spectrum (ROS) 

Three of the four management areas (MA) in the project area, MA 5.1, MA 5.4 and MA 

8.2 have a ROS of ‘roaded-natural’. This accounts for approximately 83% of the total 

project area. The remaining management area, MA 4.1, has a ROS of ‘roaded natural, 

non-motorized’. 

Developed Recreation

Forest Service developed recreation sites in the project boundary include the Forest 

Supervisor’s Office Visitor Center, Bismarck Lake Recreation Area and organizational 

Camp Bob Marshall. Several main highways for visitor access travel through the project 

area, including State Highways 16, 385, Peter Norbeck National Scenic Byway (Byway), 

Highways 16A, 89 and 87. 

Attractions located adjacent to or short drives from the project include Jewel Cave 

National Monument, Wind Cave National Park, Mt. Rushmore National Monument and 

Custer State Park. Numerous annual recreation events affiliated with other agencies and 

the State of South Dakota Mickelson Trail which occur in or near the project area include 

Sturgis Rally, Anna-Leigh Run, Mickelson Trail Trek, Lean Horse Ultra-Marathon, 

Buffalo Round-Up, Custer Gold Discovery Days, Crazy Horse Volksmarch and Crazy 

Horse Marathon/Half-Marathon. Most of these activities occur in the primary summer 

season and early fall.

Dispersed Recreation

There are also ample opportunities for dispersed recreation use of public lands year round 

in the project area to include driving for pleasure, hunting, wildlife viewing, rock 

climbing, bicycle riding, hiking and horseback riding. These activities are part of the 

“lifestyle” for local residents who reside either adjacent to or within a very short distance 

from Forest Service Lands. Year round recreation activity occurs in an interrelated mix of 
Vestal Final Environmental Impact Statement Chapter 3

147

public Federal, State, County, City and private lands in the Vestal project area. This is 

important for the local economy as well as the quality of life for residents. 

The most popular areas for dispersed recreation are Calamity Peak, Buckhorn Range, 

Custer Peak, Poverty Gulch and Meeker Ranch, home of an historic ranch farmstead. 

The Paha-Sapa Trail was decommissioned in the late 1980’s but has continued to be used 

by private citizens. The Buckhorn Range, both east and west sides, in the project area is 

a spectacular large granite ridge accessible for dispersed recreation activity from the City 

of Custer limits and/or Highways 87 and 16/385. Custer Peak is located near Stockade 

Lake with several adjacent commercial campgrounds east of the Custer. Patrons of these 

campgrounds frequent Custer Peak mainly for hiking or horseback riding on old FS 

roads. Dispersed recreation use in these areas is highest during the primary recreation 

season from May to September annually. There is moderate use during the fall and low 

use during the winter months. Group use in the project area by hikers, horse riders and 

mountain bikers, particularly on the old Paha-Sapa trail, occurs on an infrequent basis 

during the summer months. 

There are no motorized or non-motorized Forest System trails within the project area.

Recreation Special Uses 

Three Outfitter & Guide and one Organizational Camp (Camp Bob Marshall) Special Use 

Permits are issued in the project area. Please refer to Map 10 in Appendix A for specific 

locations. There are authorized roads and trails under recreation outfitter & guide special 

use permits issued to Rockin R Rides for conducting horse rides, National Outdoor 

Leadership School for teaching rock climbing/environmental education and to Outlaw 

Ranch for hiking, horse ride and hiking activities in the project area (see Permit Map 10 

in Appendix A).

Motorized Recreation 

The majority of system roads in the project area are open to public licensed vehicles. 

Open public travel roads are reflected on the Black Hills National Forest Motor Vehicle 

Use Map (MVUM) which is available free to the public and also available on the Forest 

website. The project area does not allow for off-road motorized use. The use of Forest 

system roads which are open for public travel in the project area by ATV, UTV and trail 

motorcycles is common year round except in an unusually heavy snowfall winter. 

Unauthorized off highway use of the project area is a concern and a challenge to manage 

since the implementation of the 2010 Black Hills National Forest Travel Management 

Decision.

Environmental Consequences

Alternative 1

This alternative would have a negative effect on the recreation resource if the on-going 

MPB epidemic in project area continues, as expected. The resulting increased mortality 

of dense stands of timber due to MPB infestation would cause considerable degradation 

of the visual aesthetics over a broad landscape versus a healthy green forest.
Vestal Final Environmental Impact Statement Chapter 3

148

Developed Recreation

This change in aesthetics could result in the project area being a less desirable place for 

the public to recreate and could decrease socio-economic benefits of a tourist based 

economy in the surrounding communities. There would also be high fire hazard within 

the project area due to heavy fuel loading from mountain pine beetle caused mortality. 

Large scale, high intensity wildfires reduce recreation use of an area and could also 

threaten/destroy recreation facilities in the project area such as Camp Bob Marshall and 

Bismarck Lake. 

The predicted extent of dead trees killed by MPB would have a negative impact on 

developed and dispersed recreation. The dead trees would become public hazards and 

MPB killed trees generally fall or break within 3-5 years. In addition, there would be 

increased maintenance needed within developed sites and impacts to permitted Outfitter 

and Guide authorized trails. The expense of dealing with beetle affected trees in 

recreation sites would increase as the epidemic increases and affects more trees in these 

sites. This may result in a temporary closure of recreation sites to the public if tree 

mortality from MPB attack exceeds recreation resource budgets to remove these hazards 

for public safety. 

Dispersed Recreation

Mountain pine beetle killed pine trees are a falling tree hazard to dispersed recreation 

users who frequent the area. Dispersed recreation areas are not monitored and cleared of 

hazardous trees such as is done in developed recreation sites. Dispersed recreation users 

such as horse riders, hikers, bicyclists, rock climbers, hunters, etc., can expect more dead 

and dying trees as more pine trees become infested with MPB.

Recreation Special Uses 

Recreation special use permit areas would be maintained by the permit holders to ensure 

that they are cleared of hazardous MPB infested trees and safe for the public. Therefore, 

there would likely be increased maintenance costs for permit holders to continue to use 

these permitted areas and trails.

Alternative 2

The proposed activities in this alternative would reduce MPB risk and therefore, would 

consequently reduce the potential for MPB caused mortality. It is anticipated that the 

proposed thinning and sanitation treatments would result in a healthier forest of green 

trees that would provide a more appealing area in which to recreate versus one with large 

swaths of dead trees. A forest with an under story largely absent of dead and down fuels 

and slash would provide a more open, park-like setting desired by recreationists.

The use of prescribed fire and pile burning would create periods of smoke and haze 

causing temporary negative affects to recreation opportunities over a broad area. These 

prescribed burning periods occur during the non-primary recreation tourism season, 

mostly late fall and early spring to a lesser extent. Therefore the effects to recreation are 

considered short-term and minimal.

Sale activities would create short term periods of noise, dust, increased traffic and 

disturbance to the landscape, negatively impacting recreation social opportunities for 

solitude and rejuvenation in the natural environment. These impacts would be localized 
Vestal Final Environmental Impact Statement Chapter 3

149

and relatively short-term. Vegetation management activities would be obvious during 

and following implementation. These effects on the public are largely short term 

provided the follow up fuels reduction phase of the project occurs relatively soon (2-3 

years) after harvest.

No harvest activities would occur in developed recreation sites themselves during the 

primary recreation tourism season. 

Recreation special use permits (SUPs) would experience the impacts discussed above. 

Design criteria is included to avoid harvest activity during the primary use season within 

SUP permitted areas, where possible. In addition, coordination would be required 

between permittees and Forest Service to avoid potential conflicts. Any necessary 

adjustments to permitted areas would ideally occur prior to the date that Annual 

Operating Plans are discussed and finalized between the Forest Service and permitted 

Outfitters and Guides. 

Authorized outfitter trails/areas will be protected improvements in timber sale contracts 

and prescribed burning plans. Examples of protected improvements include trail tread, 

water bars, stock bypass gates and trail tread gravel.

Travel Management 

Use of open public system roads for recreation during this project will be temporarily 

affected during periods of logging traffic and maintenance. Examples include road 

closure for grading and/or hauling of forest products. Road maintenance would occur 

during and after sale activities on affected roads enhancing their condition for post-sale 

recreation travel.

Mickelson Trail

The State of South Dakota Mickelson Trail and Mickelson Connector Trail between 

Custer and Custer State Park would be affected by the use of sections of these trails for 

harvesting timber in the Vestal project. Negative effects to these trails would be 

minimized through the use of specific design criteria (see Appendix B). 

Cumulative Effects

The cumulative effects boundary used was the project area. Time boundary for 

cumulative effects is from present to five years in the future. These boundaries were 

selected because the effects would be most evident to the project area and within five 

years of beginning the project. 

The cumulative effect of forest disturbance caused by a No Action alternative during an 

on-going mountain pine beetle infestation or the action alternative of harvest and postharvest vegetative treatments could cause a shift of recreation activity from an area of 

disturbance to one of no or lesser disturbance. Recreation use would return to all areas 

and probably increase over time as the level of disturbance tapers off in successive years.

The cumulative impact of No Action in an on-going mountain pine beetle infestation 

would result in more trees dying in larger groups over more area of the Vestal project. 

Thinning stands of trees in the action alternative results in more trees scattered over more 

area throughout the landscape when compared to the No Action alternative. This would 
Vestal Final Environmental Impact Statement Chapter 3

150

result in a more open recreation forested setting under the No Action alternative and vice 

versa for the action alternative.

Soils and Hydrology 

This section discusses the affected environment and environmental consequences of the 

No Action and proposed action alternatives for soils and hydrologic resources. It 

summarizes the Vestal Soil and Watershed specialist report, located in the project file.

Field Surveys

The field survey for the Vestal project was completed over several years, beginning in 

2007. The goal of the fieldwork is to classify streams, identify watershed problem areas 

and asses the condition of the soils. Stream classification consists of identifying whether

a stream is perennial, intermittent or ephemeral. Watershed problems need to be 

identified so the appropriate correction measures are prescribed. The soil information is 

needed to assess the condition of the soils from past activities and is needed for the 

cumulative effects analysis. Most of the blue line streams, as display on seven and half 

minute United States Geologic Survey (USGS) Quads were visited in the field. Areas 

visited for the soils assessment were distributed throughout the project area and across 

different soil map units. The results of the field work identified stream type, watershed 

problem areas and soils condition.

Affected Environment - Soils

There are 22 different soil map units within the Vestal project area. Eight (8) of the soil 

map units comprise less than 1% of the project area combined; BrB, HgB, HgD, HoD, 

MhA, Pt, VpC and W. These eight are not discussed further. Five soil map units, BtE, 

BuE, BvC, RkG and RlG, comprise 85% of the project area and the other nine soil map 

units occupy approximately 15%. Soil map units within the project area are listed in 

Table 49.

Soil Health Assessment 

Current conditions of the soils were observed when five (5) soil map units were visited in 

the field in 2007 and 2010. They were units with symbols BtE, BuE, BvC, CwB and 

HfC. These units represent 74% of the VPA. The goal was to find previously disturbed 

areas to see if there are any residual effects from past activities. Eleven (11) sites were 

observed. At nine (9) sites the R2 Soil Health Monitoring/Assessment Protocol was used 

and the findings were that all sites that were visited had Properly Functioning Soil Health 

Ratings. The other two (2) sites used the new National Soil Monitoring Protocol and 

there was not any detrimentally disturbed soil found anywhere along the transect (USDA 

Forest Service 2009b). All areas had excellent ground cover, infiltration was excellent 

and no erosion was occurring. 

Soil Erosion 

Erosion hazard is an indication of the risk of soil loss associated with disturbance. Soil 

map units with the symbols RgG, RkG and RlG have a Severe Erosion Hazard Rating

(SEHR). These units occur on steep slopes of 40-80 percent and occupy approximately 

16% of the project area. The EHR is severe because of the steep slopes. The majority 

(57%) of soils have a moderate EHR. Approximately 27% of soils have a slight EHR. 

Soil Compaction 

All soils are subject to compaction when conditions are right, but some are more prone to 

compaction than others. Activities with heavy equipment on soils can change the 

characteristics of the soils, resulting in compaction and causing more runoff or resulting 

in poor plant growth. 

Nutrient Removal

Forest Plan standard 1102 sets requirements for soils with topsoil less than one-inch, 

organic matter less than two percent, or rooting depth less than 15 inches. In the Vestal 

project area, none of the soil map units contain topsoil organic matter of less than two

percent or have rooting depths of less than 15 inches. 

There are eight (8) soil map units that have a large portion of the unit with topsoil thinner 

than one (1) inch. They are BtE, BuE, BvC, MsC, MtE, RgG, RkG and RlG and 

comprise 91% of the Vestal project area. 

Environmental Consequences - Soils

Soil Erosion – Direct and Indirect Effects

“Severe erosion can impair long-term soil productivity if soils are heavily disturbed on 

shallow or highly erodible soils. Evidence of severe erosion is rills or pedestals,” (USDA 

Forest Service 1996a). 
Vestal Final Environmental Impact Statement Chapter 3

152

Alternative 1

There would be no direct or indirect effects to soil productivity from soil erosion with 

this alternative because no new activities are planned.

Alternative 2

Ground disturbance associated with commercial treatment activities has the potential to 

impact soil productivity by creating conditions that can contribute to a greater potential 

for soil erosion. Noncommercial vegetation treatments, dead fall treatment and fuel 

break construction are not expected to have any impacts to soil productivity from soil 

erosion because the organic layer would still be present on the soil surface, protecting the 

soil from erosion. Prescribed fire is not expected to have any impacts to soil productivity 

from soil erosion because the organic layer is not expected to be burned off, thereby 

leaving some organics on the soil surface protecting the soil from erosion. Vegetation 

treatments on soils with a Severe Erosion Hazard Rating (SEHR) and steep slopes have 

the most potential to increase soil erosion. 

Approximately 2,164 acres or 9% of the treated acres are located on soils with a severe 

erosion hazard rating with slopes greater than 20% and less than 40%. One thousand one 

hundred ninety-six (1,196) additional acres or 5% of the treated acres are proposed for 

treatment on slopes greater than 40%. Minimal soil erosion may occur from the 

commercial activities but implementing the Forest Plan standards and guidelines, 

including WCPs and BMPs, and the design criteria “On soils with severe erosion hazard

rating and slopes between 20 and 40%, machinery operations must be restricted to dry or 

frozen soil conditions” and “On soils with severe erosion hazard rating and slopes steeper 

than 40%, ground skidding must be avoided” there would be very little soil erosion 

occurring, and only for short distances. The potential for erosion related to roads would 

be minimized with proper erosion control structures at proper spacing for the grade of the 

road. These would be built in the road and be maintained throughout the operation and 

also upon putting the roads to bed. 

Direct or indirect effects to soil productivity from soil erosion are not expected because 

very little erosion is expected to occur from this alternative with the implementation of 

the Forest Plan standards and guidelines, including WCPs and BMPs, and the design 

criteria. 

Soil Compaction – Direct and Indirect Effects

“Soil compaction is caused by excess weight of vehicles and animals. It impairs 

infiltration, root growth, and soil biota,” (USDA Forest Service 1996a). 

Alternative 1

There would be no direct or indirect effects to soil productivity from soil compaction 

with this alternative because no new activities are planned.

Alternative 2

This alternative may have short-term impacts but the impacts are not expected to persist. 

Minimal soil compaction can occur from the commercial activities. BMP monitoring of 

timber units in the Black Hills since 2005 (USDA Forest Service 2008, 2009 & 2010) 

have shown some impacts occur but all units met Forest Plan Standards. If compaction
Vestal Final Environmental Impact Statement Chapter 3

153

does occur it would generally be expected to be reduced over time meaning no long-term 

effects. Forest Plan Monitoring on one site has shown “there is evidence that conditions 

were such that within one geographic area, on at least one soil type, and to the depth 

sampled, that the mean soil bulk density decreased from levels above the threshold 

classified as “detrimental compaction” to levels below the threshold within the time 

period of one year” (USDA Forest Service 2009). 

No indirect effect on soil productivity from soil compaction with this alternative is 

expected. Short-term direct effects can occur but are not expected to persist.

Nutrient Removal – Direct and Indirect Effects

“Soil fertility depends on organic matter and nutrients. Soil productivity can be degraded 

if humus and topsoil, or even excess leaves and limbs, are taken off site,” (USDA Forest 

Service 1996a). 

Alternative 1

There would be no direct or indirect effects to soil productivity from nutrient removal 

with this alternative because no new activities are planned.

Alternative 2

This alternative includes commercial and non-commercial vegetation management, dead 

fall treatment, fuel break construction and prescribed fire. Noncommercial vegetation 

management, dead fall treatment, fuel break construction and prescribe fire do not affect 

soil productivity from nutrient removal because organic material is not physically 

removed from the site. Lopping, chipping, crushing, or mastication leaves all material on 

site. Burning will change the form or composition of the nutrients but most will be still 

available on site.

Commercial vegetation management generally removes whole trees from the site in order 

to reduce the fuels in the stand. This could pose a concern on some soils, however with 

the mountain pine beetle activity in the Vestal project area, there would be sufficient

material left on site to meet Standard 1102, including Guideline 1102a, and soil 

productivity would not be affected

No direct or indirect effects on soil productivity related to soil nutrients are expected to 

occur with this alternative. 

Soil Heating – Direct and Indirect Effects

“Soil heating is caused by severe fires that occur when humus and large fuels are dry and 

large fuels are consumed near the ground. Soil heating sterilizes the soil, alters soil 

physics, consumes organic matter, and removes much of the site’s nutrients,” (USDA 

Forest Service 1996a). Impacts to soil productivity from soil heating usually occurs as a 

result of a wildfire but can occur in small areas with prescribe fire.

Alternative 1

There would be no direct or indirect effect to soil productivity from soil heating with this 

alternative because no new activities are proposed within the project area.

Alternative 2

Effects from soil heating can occur from burning of slash piles and prescribed fire.
Vestal Final Environmental Impact Statement Chapter 3

154

Burning slash piles would cause detrimentally impacted soils from soil heating in small 

isolated locations throughout the project area. Any runoff from these small areas of 

detrimental impact would be absorbed by adjacent area. Concerns regarding soil heating 

come from large contiguous areas, which would not occur as the result of this project. 

Prescribed burning is proposed on approximately 1,761 acres. There is potential for soil 

heating to occur as a result. However, design criteria to “conduct prescribed fires to 

minimize the residence time on the soil while meeting the burn objectives, this is usually 

done when the soil and duff are moist” would minimize the potential effects to the soil 

from soil heating. No direct or indirect effects to soil productivity from soil heating are 

expected with this alternative. 

Cumulative Effects - Soils

The spatial boundaries of the cumulative effects analysis for the soils resource is the 

proposed activity units in the project area. The effects of the alternatives on the soils 

resource would be contained within the units. The time frame for the cumulative effects 

discussion is from year 2002 through 2021, ten years before and ten years after. These 

dates include impacts from recent timber harvesting in the past and extend forward to 

include the estimated completion of activities proposed in this project. The past, present, 

and future activities considered in this analysis are presented in Appendix F. 

Forest Plan standards and guidelines, as well as site specific design criteria would be 

implemented in the proposed action. When implemented as described, no adverse 

cumulative effects to soils are expected to occur. Past monitoring shows that when 

Forest Plan standards and guidelines are implemented on similar projects, this standard is 

met (USDA Forest Service 2008, 2010a, 2010b). It is further expected that the 

compacted, eroded, or displaced condition would be less than 15%, as described in 

Standard 1103. The following discussion considers the cumulative effects of potential 

disturbances to long-term soil productivity in accordance with Forest Plan Standard 1101. 

Nutrient Removal

There would be no adverse cumulative impacts to soil organic matter and nutrients from 

any alternative within the project area because sufficient residual material and trees 

would be left on site for nutrient recycling after project implementation. Forest Plan 

Standard 1102 would be met. 

Soil Heating 

Events that could cause negative effects of soil heating are wildfires and, to a lesser 

degree, prescribed burning. Prescribed burning within the project area would be 

implemented in a manner designed to reduce the potential for adverse soil heating 

impacts. Prescribed burning would have beneficial effects by reducing long-term fire 

hazard and the potential for large-scale, high intensity wildfire that could have soil 

heating effects. Therefore, no adverse cumulative effects would be expected under any 

alternative.

Soil Erosion 

Past, currently ongoing, and reasonably foreseeable actions listed in Appendix F were 

considered along with proposed activities for cumulative effects to soil erosion and 
Vestal Final Environmental Impact Statement Chapter 3

155

displacement. Any soil erosion that may occur related to implementation of the Vestal 

project is expected to be localized, minor in both severity and extent, and thus well below 

levels that would be considered detrimental. This expectation also applies to other forest 

management activities and uses. Design criteria and appropriate WCP/BMP measures 

apply to all forest management activities and uses. These measures are designed to 

control runoff and erosion for a 10 year storm event (USDA Forest Service 2006b). 

Therefore the risk of cumulative detrimental soil erosion is mitigated for typical storm 

events observed in the Black Hills for all forest management activities.

Grazing management throughout the project area is not expected to cause extensive soil 

erosion. Dispersed recreation activities generally do not cause excessive soil erosion 

issues due to the lack of concentrated use. Concentrated recreation sites are purposely 

located in flatter terrain which minimizes the potential for soil erosion and employs 

management strategies to guide concentrated uses where measures are in place (i.e. 

WCPs/BMPs) to minimize soil erosion. 

Any soil erosion as a result of the Vestal project would be expected to be minimal and 

would be within the limits of Forest Plan Standard 1103 for Alternative 2. There would 

be no cumulative effects to soil erosion resulting from the No Action alternative.

Soil Compaction 

Past, currently ongoing, and reasonably foreseeable actions in the Vestal project area 

were considered along with proposed activities for cumulative effects to soil compaction. 

Any soil compaction that may occur related to implementation of the Vestal project is 

expected to be localized and well below levels that would be considered detrimental. 

This expectation also applies to other forest management activities and uses. Design 

criteria and appropriate WCP/BMP measures apply to all forest management activities 

and uses. Therefore the risk of cumulative detrimental soil compaction is minimized. 

Grazing management throughout the project area is not expected to cause detrimental 

levels of soil compaction due to where livestock naturally tend to roam and the presence 

of rock fragments in most of the soils within the project area. Dispersed recreation 

activities also do not tend to cause detrimental soil compaction due to the lack of 

concentrated use for this type of recreation. 

Any soil compaction would be expected to be minimal and would be within the limits of 

Forest Plan Standard 1103 for Alternative 2. There would be no cumulative effects to 

soil compaction resulting from the No Action alternative.

Affected Environment – Hydrology

Watersheds

Watershed boundaries and HUC codes were obtained from the National Hydrography 

Dataset developed and maintained by the USDA Service Center and USGS (USDA 

NRCS 2009). The Vestal project boundary overlaps portions of seven HUC 12 (6th level) 

watersheds (see Table 50). Since the project area does not coincide exactly with 

watershed boundaries, the water resources analysis area differs from the project area 

boundary.

In 2011Watershed Condition Framework (WCF) (USDA Forest Service 2011a) was 

implemented by the Forest Service. It is a comprehensive approach for classifying 

watershed condition, proactively implementing integrated restoration in priority 

watersheds on national forests and grasslands, and tracking and monitoring outcomebased program accomplishments for performance accountability. 

Watershed condition is the state of the physical and biological characteristics and 

processes within a watershed that affect the soil and hydrologic functions supporting 

aquatic ecosystems. There are four (4) watersheds that have a substantial portion of their 

area within the Vestal project area, Ruby Creek-French Creek, Stockade Lakes-French 

Creek, Glen Erin Creek-French Creek and Newton Fork-Spring Creek. All are rated 

Class 2 watersheds, “Functioning at Risk”.

Watershed condition classification is the process of describing watershed condition in 

terms of discrete categories (or classes) that reflect the level of watershed health or 

integrity. The three watershed condition classes that are directly related to the degree or 

level of watershed functionality or integrity; 

Class 1 = Functioning Properly – exhibit high geomorphic, hydrologic, and biotic 

integrity relative to their natural potential condition.

• Riparian/wetland areas that are functioning properly exist when adequate 

vegetation, landform, or large woody debris is present to dissipate stream 

energy associated with high waterflow, thereby reducing erosion, improving 

water quality, etc. 

Class 2 = Functioning at Risk – exhibit moderate geomorphic, hydrologic, and 

biotic integrity relative to their natural potential condition. 

• Riparian/wetland areas that are in functional condition, but one or more 

existing soil, water, or vegetation attributes makes them susceptible to 

degradation. 

Class 3 = Impaired Function – exhibit low geomorphic, hydrologic, and biotic 

integrity relative to their natural potential condition. 

• Riparian/wetland areas that clearly are not providing adequate vegetation, 

landform, or large woody debris to dissipate stream energy associated with 

high flows, and thus are not reducing erosion, improving water quality, etc. 
Vestal Final Environmental Impact Statement Chapter 3

157

(USDA Forest Service 2011c)

Floodplains 

A floodplain is the flat area on either side of a stream or river that is susceptible to 

inundation by floodwaters. Floodplains slow flood velocities and decrease erosion 

because they are by nature wide and flat, thus allowing for shallower and slower water. 

Thus, floodplains provide for flood moderation, water quality protection, ground water 

recharge, and wildlife habitat, among other benefits. The Federal Emergency 

Management Agency (FEMA) has mapped 100-year floodplains across the nation 

(FEMA 1998). 

There are approximately 267 acres of mapped 100-year floodplains within the Vestal 

project area on National Forest. Mapped 100-year floodplains are located along the 

following streams and drainage ways: French Creek, Glen Erin Creek, Laughing Water 

Creek, Loues Creek, North Fork French Creek, Ruby Creek, Tenderfoot Creek and 

Willow Creek.

Wetlands and Riparian 

Wetlands were mapped during a national effort and recorded in the National Wetland 

Inventory (NWI). There are approximately 67 acres of wetlands within the Vestal project 

area. 

One of the mapped wetlands is Bismarck Lake, classified as Lacustrine Systems. The 

term Lacustrine is related to the word ‘lakes’ and thus a lacustrine wetland is, by 

definition lake-associated. The Lacustrine system includes wetlands and deepwater 

habitats that are greater than 20 acres and have less than 30 percent cover of persistent 

vegetation (Water Word Glossary 2009). 

The rest of the mapped wetlands are classified as Palustrine Systems. "Palustrine" comes 

from the Latin word "palus" or marsh. Wetlands within this category include inland 

marshes and swamps as well as bogs, fens, tundra and floodplains. Palustrine systems 

include any inland wetland, which lacks flowing water and contains ocean derived salts 

in concentrations of less than 0.05%. 

Lakes

There is one lake within the Vestal project area, Bismarck Lake. It is 25 acres in size and 

is form by a dam constructed by the CCC (Civilian Conservation Corps) on an unnamed 

tributary to French Creek. The outflow from the Bismarck Lake flows for approximately 

600 feet and then empties into Stockade Lake in Custer State Park. 

Streams 

There are an estimated 135 miles of streams within the Vestal project area. Sixty-seven 

percent (67%) or 91 miles are on private land, leaving 44 miles on National Forest. Of 

the 44 miles of streams on National Forest, 33 % are perennial, 12% are intermittent and 

55% are ephemeral (See Map 9 in Appendix A). 

Streams on National Forest within the Vestal project area are identified on Map 9, 

Appendix A. Identification of whether each stream on National Forest is Ephemeral, 

Intermittent or Perennial was based on field survey and review of USGS Quad maps. 

Perennial and intermittent streams have a 100 foot WIZ along them and will be identified 
Vestal Final Environmental Impact Statement Chapter 3

158

as a protected stream course. The WIZ distance is from the high water mark and is on 

each side of the stream for a total of at least 200 feet. Table 51 displays the streams by 

name.

Beneficial Uses

The South Dakota (SD) Department of Environment and Natural Resources (DENR) 

assigns water quality standards based on the beneficial uses of each water body. All 

streams and lakes in SD are assigned the beneficial uses of fish and wildlife propagation, 

recreation and stock watering. Streams are also assigned the beneficial use of irrigation. 

Within the Vestal project area the streams in Table 52 have additional designated 

beneficial uses, as noted.

Streamflow Regime 

Streamflows throughout the Black Hills have been reduced over the last century. This 

has been a result of fire suppression. There has been an increase of woody biomass. 

Higher leaf areas from increased woody biomass will increase evapotranspiration and 

interception, resulting in lower streamflows and the drying of springs (USDA Forest 

Service 2003b). 

Peak flows data has been collected for a limited time on several streams in an around the 

Vestal project area. The streams include; French Creek, three (3) sites, two (2), six (6) 

and 19 years; Laughing Water Creek, six (6) years; and Ruby Creek, six (6) years. Peak 

flows on these creeks occurred from March to October with the most occurring in June 

(USGS 2011). 

Stream Health 

Perennial and intermittent streams within the project area were reviewed to determine 

Stream Health Rating (SHR). Stream health is defined as “ The condition of a stream 

versus reference conditions for the stream type and geology, using metrics such as 

channel geometry, large woody debris, substrate, bank stability, flow regime, water 

chemistry and aquatic biota” (USDA Forest Service 2006b), is an indicator of water 

quality. It is a good way to give an overview of a stream and a means to compare them to 

each other. Many streams have the majority of their length on private lands. Those 

perennial and intermittent streams with very minor amounts on National Forest lands 

were not assigned a SHR. The remaining streams were assigned SHR as discussed 

below: 

French Creek – Is a major tributary to the Cheyenne River. The entire length is 

86.2 miles. Sixteen percent (16%), or 13.7 miles, of this stream is in the Vestal 

project area. Of that portion, 76% is on private land and 24% is on National

Forest. There are two distinct reaches, above Stockade Lake and below Stockade 

Lake. The reach above Stockade has many impacts with a significant amount of 

stream crossings, significant grazing on private land, and channelization in the 

City of Custer, to highlight some impacts. The reach below Stockade Lake had 

significantly less impacts with a few road/stream crossings that could be 

improved. Most crossings are on county roads. The SHR for French Creek above 

Stockade Lake would be diminished and French Creek below Stockade Lake 

would be At-Risk. 

Glen Erin Creek – Approximately 98% (4.5 miles), is within the Vestal project 

area. Only 0.1 miles is outside the project area. Forty percent (40%) is on private 

land. There are two distinct reaches on National Forest. One reach has had CCC 

activity on it, building dams and building restoration structures in the stream. 

Two of the dams are no longer functioning and one is holding water and creating 

a nice pond. The restoration work has created wonderful wetlands along the 

stretch that was restored. The SHR for this reach would be At-Risk. The other 

reach, or lower reach, has been acquired recently and the stream has not been 

grazed for a number of years. This reach has a SHR of Robust. 

Ruby Creek – The entire length of this stream, 6.7 miles, is within the Vestal 

project area, however 69% of this stream is located on private land. Two (2) 
Vestal Final Environmental Impact Statement Chapter 3

160

miles are on National Forest. Some of Ruby Creek that is on National Forest is 

on the French Creek Allotment. The stream health on this section of Ruby Creek 

was identified as At-Risk in the Hell Canyon 2010 Range Project and it would be 

the same today.

Toe (Joe) Gulch – Seventy-one percent (71%), 1.3 miles, of 1.8 miles total length 

of this stream is within the Vestal project area. Very little of this stream, six 

percent (6%) is on private land. This stream is within the French Creek 

Allotment. In the past the valley along the stream has been grazed and continues 

to be grazed today but under new management plans. The SHR for this stream is 

At-Risk. 

Connected Disturbed Area (CDA) 

CDAs are areas that are identified that contribute sediment to streams or wetlands 

causing degradation of physical function, degraded water quality and increased peak 

flows that may alter physical channel processes. When a disturbed area flows into a 

waterbody without sufficient delay from vegetated filter strips or sediment detention 

structures, it is connected to the waterbody. CDAs may include bare soil patterns, 

compacted soils, roads, severely burned areas or mine spoils. 

Disturbed areas near ephemeral drainages are generally not CDAs. This is because there 

is vegetation in the drainages that would filter out any erosion generated. This erosion 

does not contribute to the degradation of the physical function of the stream or degrade 

water quality.

During field inventory, 10 CDAs were identified, all of which are road crossings. Four 

(4) were on Forest Service roads and six (6) were on County roads. The CDAs were 

distributed across three (3) HUC 12 watersheds. 

Water Quality

The State of South Dakota maintains a list of waterbodies that do not meet water quality 

standards for their assigned beneficial uses. There is one (1) stream, within the Vestal 

project area, French Creek, that is currently on the SD 303(d) Waterbody List (SD DE 

NR 2010). 

French Creek is on the list for not meeting the beneficial use of Coldwater Marginal Fish 

Life and Limited Contact Recreation. The parameter of concern is dissolved oxygen. 

The listed cause is natural sources and drought related impacts. The South Dakota 

Department of Environment and Natural Resources conducted a monitoring program 

from March through October of 2010 at several sites along this reach. No violations 

related to dissolved oxygen were observed or recorded during this sampling period. 

(Robert Smith, personal communication, March 1, 2011) 

All other streams and waterbodies within the Vestal project area are meeting their 

assigned beneficial uses. 

Environmental Consequences - Hydrology

The water resources analysis area encompasses the headwater portions of Redbird and 

Gillette Canyons, an area totaling approximately 50,820 acres (Appendix A, Map 6). The 
Vestal Final Environmental Impact Statement Chapter 3

161

water resources analysis area includes land managed by both the Mystic and Hell Canyon 

Ranger Districts of the Black Hills National Forest, as well as private lands. 

Potential impacts to water resources include impacts to aquatic ecosystems, special areas, 

and soil productivity (discussed earlier). Aquatic ecosystems include physical conditions 

(sediment, bed/bank stability and flow regimes), chemical conditions 

(temperature/oxygen and water purity) and biological conditions (aquatic life). The 

Alternatives may impact these conditions in the project area, as discussed below. 

Past, currently ongoing, and reasonably foreseeable actions listed in Appendix F were 

considered along with proposed activities for cumulative effects to water resources. 

Aquatic Ecosystems 

Sediment – Direct and Indirect Effects

Alternative 1

This alternative would not have any new activities occur within the project so sediment 

levels would remain unchanged. There would be no direct or indirect effects to the 

aquatic resource due to sediment. 

Alternative 2

Mechanical vegetation treatments are proposed on approximately 251 acres within the 

100 foot WIZ (Water Influence Zone). Approximately half of these acres are within 50 

feet of the water source. There would be no direct effects of sedimentation from 

commercial vegetation treatments. 

Prescribed burning is proposed on approximately 121 acres within the WIZ. As with 

mechanical treatments, approximately half of these acres are within 50 feet of the water 

source. The potential to generate sediment from prescribed fire is low because soils 

within the WIZ and next to the streams are generally wetter. There would be no direct 

effects of sedimentation from prescribed fire. 

Maintenance and temporary use of roads within the WIZ and at stream crossings have the 

potential to increase sediment because the road surface is disturbed during operations and 

material on the road can be easily mobilized during precipitation events. There are 

approximately 7 miles of existing roads within the WIZ in the Vestal project area. 

Slightly less than half are within 50 feet of the water source. No new system roads would 

be constructed in the WIZ. 

There are also approximately 40 existing stream crossings. It is expected that some 

sediment would be produced at these crossings. It is extremely difficult to quantify how 

much sediment would be produced, so the amount of activity within the WIZ is used as a 

comparison. 

None of the crossings on reconstructed routes would be disturbed. There would 

potentially be three (3) constructed crossings on perennial streams. One would be on a 

reconstructed road and two on temporary roads. The reconstructed crossing is on French 

Creek, NFSR 342.1E, and will be a temporary bridge. The temporary road crossings will 

be on Ruby Creek and Meeker Creek and both would require a structure to span the 

stream such as a temporary bridge, cattle guard, temporary arch or similar structure. All 

new structures would be removed and rehabilitated upon completion of the project. In 
Vestal Final Environmental Impact Statement Chapter 3

162

addition to the three crossings, a culvert on a level 1 road, NFSR 297.1I, would be 

removed upon completion of its use. 

Some sediment is expected to be introduced to the streams at these locations, but not in 

quantities that would affect the aquatic resource. 

Alternative 2 may generate sediment from mechanical treatments, prescribed burning, the 

use of existing roads or stream crossings. However, with the implementation of Forest 

Plan Standards and Guidelines, WCPs, BMPs and design criteria, the potential to 

generate sediment from mechanical treatments or prescribed fire, is low. Some sediment 

is expected to be generated from use of existing roads and stream crossings, however the 

amount would be minimal, and in quantities that would not affect the aquatic resource. 

As a benefit of the activities, three (3) CDAs on Forest roads would be corrected.

There would be a slight increase in potential for sedimentation from the action alternative 

in the short term (<5 years) due to activities related to road crossings usually at the 

crossings. In the long term (>5 years) sediment potential would be reduced by the action 

alternative as compared to existing conditions because of the repair or fixing of some of 

the CDAs.

Bed and Bank Stability – Direct and Indirect Effects

“Bed and bank stability can be damaged from trampling by animals or humans, vehicle 

impact, degraded bank vegetation, or excessive flow augmentations. Streams can be 

made wider and shallower, pools and overhanging banks can be destroyed, and much 

sediment can be added to streams,” (USDA Forest Service 1996a). 

Alternative 1

No direct or indirect effects to bed and bank stability would occur.

Alternative 2

This alternative would not have an impact on bed and bank stability within the Vestal 

project area. Skid and forwarding trails have the potential to cross perennial and 

intermittent streams. When this occurs, design criteria for forwarding and skid trails 

would be implemented to protecting bank stability. By implementing the design criteria 

and this alternative would have no direct or indirect impacts. 

Stream Flow Regime – Direct and Indirect Effects

“Flow regimes can be altered by major changes in cover type or ground cover, dense road 

networks, or water projects. Water temperature and chemistry, sediment transport, 

aquatic habitats, and aquatic life cycles can be degraded” (USDA Forest Service 1996a). 

Large change to flow regimes in the Black Hills would occur if a large precipitation event 

occurs or if a wildfire burns a large portion of the watershed. Vegetation management 

(timber harvest) and tree mortality (MPB) would affect the flow regime minimally by 

increasing the base flows. 

Alternative 1

There would be no direct effects to flow regime. Indirect effects include an increase in 

the amount of water available for streamflow and ground water recharge due to MPB 

caused tree mortality. 
Vestal Final Environmental Impact Statement Chapter 3

163

Alternative 2

Commercial and non-commercial timber activities which remove live biomass would 

positively affect flow regime. Prescribed burning could also result in a positive impact to 

flow regime due to resulting tree mortality. This would be minimal since mortality limits 

are included. 

This alternative would have a positive effect on flow regime by the removal of live 

vegetation from the landscape and would result in improved flow regimes over 

Alternative 1 by reducing the live biomass across the landscape. 

Temperature and Oxygen – Direct and Indirect Effects

“Summer water temperature is increased, and winter water temperature is decreased, by 

removing shade, reducing low flows, or damaging banks so streams are wider and 

shallower. Dissolved oxygen is usually reduced when summer water temperature is 

increased. Such impacts impair or destroy the suitability of water bodies for aquatic 

biota,” (USDA Forest Service 1996a). 

Alternative 1

No direct effects would occur. An indirect effect would occur if the live biomass 

decreases over time due to tree mortality from Mountain Pine Beetle. This could affect 

stream temperature/oxygen, by making more water available for streamflow because of 

reduced evapotranspiration. More water in the stream could mean stable water 

temperature and oxygen levels.

Alternative 2

This alternative would have a positive but minimal impact on stream temperature and 

oxygen because live biomass would be reduced, resulting in more water being available 

for streamflow. Increases in water amounts would help maintain stream temperatures.

This alternative is similar to the No Action alternative with the expected indirect effect 

due to the MPB. Water temperature and oxygen levels are expected to be maintained 

throughout the project area and French Creek because more water would be available for 

streamflow and with the implementation of the design criteria for the WIZ. 

Water Purity – Direct and Indirect Effects

“Water purity can be degraded by placing concentrated pollutant sources near water 

bodies, applying harmful chemicals in or near water bodies, or intercepting hazardous 

rock strata by roads. Degrading water purity can impair or destroy use of the water by 

aquatic biota and humans,” (USDA Forest Service 1996a). 

Alternative 1

This alternative would not have any direct or indirect effects on water purity.

Alternative 2

None of the proposed activities involves placing concentrated pollutant sources near 

water bodies or applying harmful chemicals near water bodies. There would be no direct 

or indirect effect to water purity.
Vestal Final Environmental Impact Statement Chapter 3

164

Aquatic Life – Direct and Indirect Effects

“Aquatic life can be degraded by migration barriers, changed flow regimes, riparian

damage, or big sediment loads or chemical loads,” (USDA Forest Service 1996a). Flow 

regimes, riparian ecosystems, sediment, and purity are discussed in this section. The 

items that will be discussed in this section will be migration barriers.

Alternative 1

No direct or indirect effects would occur to aquatic life from Alternative 1. 

Alternative 2

This alternative would not increase or decrease any migration barriers because temporary 

bridges or other structures which allow unimpeded streamflow would be used at stream 

crossings. No direct or indirect effects would occur to aquatic life from migration 

barriers or riparian damage.

Riparian Ecosystems – Direct and Indirect Effects

“Riparian ecosystems provide shade, bank stability, fish cover, and woody debris to 

aquatic ecosystems. They also provide key wildlife habitat, migration corridors, 

sediment storage and release, and surface-ground water interactions. Composition and 

structure of riparian vegetation can be changed by actions that remove certain species age 

classes,” (USDA Forest Service 1996a). 

Alternative 1

This alternative would not have any new activities within the project area so there would 

be no direct or indirect effect on riparian ecosystems. 

Alternative 2

There would not be any commercial activities or new system roads within any riparian 

areas. There are two proposed temporary road crossings of Ruby Creek and Meeker 

Creek. This crossing would require the road to temporarily span the stream. No other 

riparian impacts are expected. Therefore, minimal negative impacts may occur as a result 

of the proposed project. If prescribed fire were to occur in riparian areas, it would be a 

light burn because conditions in these areas are usually moist, resulting in no impacts. 

There would be minimal short-term negative direct effect on the riparian ecosystems. 

Wetlands – Direct and Indirect Effects

“Wetlands control runoff and water quality, recharge ground water, and provide special 

habitats. Actions that may alter their ground cover, soil structure, water budgets, 

drainage patterns, and long-term plant composition can impair these values,” (USDA 

Forest Service 1996a). 

Alternative 1

This alternative would not have any new activities within the project area so there would 

be no direct or indirect effects on wetlands. 
Vestal Final Environmental Impact Statement Chapter 3

165

Alternative 2

No mechanical treatments or roads are proposed within wetlands. Prescribed fire in 

wetlands would be a light burn because conditions in these areas are inherently moist, 

resulting in no impacts. There would be no direct or indirect effects on wetlands.

Floodplains – Direct and Indirect Effects

“Floodplains are natural escape areas for floods that temper flood stages and velocities,” 

(USDA Forest Service 1996a). 

Alternative 1

This alternative would not have any new activities within the project area so there would 

be no direct or indirect effects on floodplains. 

Alternative 2

Roads are the main concern within floodplains because road fills are usually placed in 

floodplains to facilitate road crossings of streams. This interrupts flood flows and can 

change the elevation of flood waters. Timber harvest activities do not affect floodplains 

because floodplains are not altered during the activity. Dead fall treatment, fuel break

construction and prescribe fire does not alter floodplains. Since no new roads are 

proposed as part of this project, there would be no impacts to floodplains. There would 

be no direct or indirect effect on the floodplains. 

Watershed Condition Class – Direct and Indirect Effects

Watershed condition is the state of the physical and biological characteristics and 

processes within a watershed that affect the soil and hydrologic functions supporting 

aquatic ecosystems. Watershed condition reflects a range of variability from natural 

pristine (functioning properly) to degraded (severely altered state or impaired) (USDA 

Forest Service 2011a).

Alternative 1

This alternative would not have any new activities within the project area so there would 

be no direct or indirect effects on the watershed condition class. 

Alternative 2

This alternative includes commercial and non-commercial vegetation management, dead 

fall treatment, fuel break construction and prescribed fire. The four (4) watersheds would 

receive 11% to 43% of their areas with some form of treatment. The proposed activities 

in the watersheds would follow the design criteria, FPS&Gs, and WCPs and there should 

not be a change in the watershed condition class to move these watersheds to a Class 3 

watershed. There would be no direct or indirect effects on the watershed condition class. 

Cumulative Effects - Hydrology

The spatial boundaries of the cumulative effects analysis for water resources are the HUC 

12 watershed boundaries that have at least 15% of their area within the project area. 

Watersheds with lesser amounts of the project area within them would have negligible 

cumulative effects from this project. Four (4) HUC 7 watersheds are used in this 

analysis. They are identified in Table 53. 
Vestal Final Environmental Impact Statement Chapter 3

166

 The time frame for the cumulative effects discussion is from year 2002 through 2021, ten 

years before and ten years after. These dates include impacts from recent timber 

harvesting in the past and extend forward to include the estimated completion of 

activities proposed in this project.

101201090603 Glen Erin Creek-French Creek 17,419 28%

101201090903 Newton Fork-Spring Creek 24,423 15%

Past, present and future land uses and events within these watersheds have. Commercial 

treatments, precommercial thinning, fuelbreaks, pine encroachment, wildfire, prescribe 

fire, grazing, weed spraying, mining, abandoned mines, mine reclamation, developed 

recreation, dispersed recreation, dam building (Bismarck and Stockade Lake), City of 

Custer, private land ownership, private land development and roads are some of the land 

uses and events that have occurred. All of these activities or events individually have an 

impact on the watersheds. 

Sediment 

There would be a slight increase in potential for sedimentation from the action alternative 

in the short term (<5 years) due to activities related to road crossings usually at the 

crossings. In the long term (>5 years) sediment potential would be reduced by the action 

alternative as compared to existing conditions because of the repair or fixing of three 

known CDAs. As a benefit of the activities, three (3) CDAs on Forest roads would be 

corrected.

Any sediment as a result of the Vestal project would be expected to be minimal for 

Alternative 2. There would be no cumulative effect to aquatic ecosystem from sediment 

from the No Action alternative.

Bed and Bank Stability 

There would be no cumulative effects to bed and bank stability. This watershed feature 

would not have direct or indirect effects, as discussed above. 

Stream Flow Regimes

Changes to flow regimes, increased water, would occur with either alternative due to 

predicted MPB mortality and in Alternative 2, proposed treatments. This would add to 

other increases in flow, such as MPB caused mortality adjacent to the analysis area and 

be a positive cumulative effect for both alternatives.

Temperature and Oxygen 

Impacts to the aquatic ecosystem from temperature/oxygen would occur from the Vestal 

Project. This impact would be a positive effect for both alternatives. 

Impacts to aquatic ecosystems from temperature/oxygen are expected to be minimal and 

would not be detectable if temperature were being monitored. 
Vestal Final Environmental Impact Statement Chapter 3

167

Water Purity

There would be no cumulative effects to water purity. This watershed feature would not 

have direct or indirect effects, as discussed above.

Aquatic Life

There would be no cumulative effects to aquatic life. This watershed feature would not 

have direct or indirect effects, as discussed above.

Riparian Ecosystems 

Impacts to the riparian ecosystem as a result of the Vestal Project would occur. This 

would add to what has already occurred (roads, private land development, grazing) in the 

watershed creating a cumulative impact. Impacts to riparian ecosystems are expected to 

be minimal and temporary for Alternative 2. There would be no cumulative effects to 

riparian ecosystems resulting from the No Action alternative.

Wetlands 

There would be no cumulative effects to wetlands. This watershed feature would not 

have direct or indirect effects, as discussed above.

Floodplains 

There would be no cumulative effects to floodplains. This watershed feature would not 

have direct or indirect effects, as discussed above.

There would be no cumulative effects to watershed condition class. The Watershed 

Condition Class for each watershed would remain unchanged from Class 2 as a result of 

this project. None of the alternatives proposes enough activities to change the ratings.

Best Management Practices (BMP) Effectiveness

BMPs by definition are “Common-sense actions required, by law, to keep soil and other 

pollutants out of streams and lakes. BMPs are designed to protect water quality and to 

prevent new pollution” (IFPC 2003). BMPs are implemented to control or limit nonpoint source pollution. 

“BMPs are developed by the State of SD...to ensure compliance with federal and state 

water-quality standards,” (USDA Forest Service 2006c). They provide good guidance 

but are fairly general. WCPs are practices to protect soil, aquatic, and riparian systems. 

USDA Forest Service, Region 2, developed them. They are more specific with design 

criteria. “If used properly, they meet or exceed State BMPs,” (USDA Forest Service, 

2006b). BMPs and WCPs are incorporated into the Forest Plan standards and guidelines 

and provide more specific direction. 

The Black Hills National Forest completed a Forest Plan BMP Evaluation (USDA Forest 

Service 2003a). Two studies done on the Black Hills National Forest by the Black Hills 

Forest Resource Association, 2001 and Wyoming Timber Industry Association, 2001, 

reviewed BMP effectiveness. The conclusion is “These results highlight the consistent 

application and effectiveness of BMPs in the Black Hills and other National Forests” 

(USDA Forest Service 2003a). The evaluation goes on to review other studies or reports 

and comes to the conclusion that “These studies highlight the effectiveness of BMPs in 
Vestal Final Environmental Impact Statement Chapter 3

168

forests throughout the United States” (USDA Forest Service 2003a). This evaluation 

shows that BMPs are effective. Since this evaluation has been completed field audits 

were completed in 2004 and 2009 in SD (Black Hills Forest Resource Association 2005, 

2009). Results showed application of BMPs were 92% in 2004, 95% in 2009, compared 

to 82% in 2001 and effectiveness of the BMPs was 95% in 2004, 95% in 2009, compared 

to 84% in 2001. This additional information shows the continued application and 

effectiveness of BMPs in SD. “The audit results from 2001, 2004 and 2009 have 

established a positive trend of on the ground BMP improvement” (Black Hills Forest 

Resource Association 2009). 

Additional BMP/WCP monitoring was completed on the Hell Canyon Ranger District, 

for 2002 through 2010. A summary report and subsequent yearly reports show that the 

BMP/WCP are being implemented and are effective and states, “Logging practices on the 

Hell Canyon Ranger District have not had any negative impact on the watershed and 

streams and that they do comply with the requirements of the CWA” (USDA Forest 

Service 2008, 2009 & 2010). 

The Vestal project would have WCPs and BMPs prescribed and implemented. This 

would protect the water quality of the streams and creeks in the project area and the 

activities that are planned would meet the requirements of the CWA.

Climate Change

The mission of the USDA Forest Service is to sustain the health, diversity, and 

productivity of the Nation’s forests and grasslands to meet the needs of present and future 

generations. The agency recognizes that climate change is an important emerging issue. 

To help guide agency actions in addressing this challenge, the Forest Service has 

developed the Strategic Framework for Responding to Climate Change (USDA Forest 

Service 2008b). One of the stated goals in this framework is to promote the management 

of forests and grasslands to reduce the buildup of greenhouse gasses, while sustaining the 

multiple benefits and services of these ecosystems. This project contributes toward 

meeting the agency’s goal of mitigating the buildup of greenhouse gasses by managing 

the forest landscape within the project area so that it is more resilient to deforestation or 

catastrophic loss. Thereby maintaining or increasing its ability to sequester carbon. 

Socio-Economics 

This section discusses the pertinent existing social and economic conditions and potential 

consequences resulting from the Vestal Project. 

Forest resources provide economic components of community sustainability by providing 

for a wide variety of uses, values, products, and services. The resources within the Black 

Hills National Forest have provided an economic array of benefits to the residents of the 

Black Hills area. These resources range from sustenance for American Indian tribes, logs 

used to construct early mining camps, towns and mines, ties used for railroad 

construction, and the lumber harvested by the timber industry, which remains active 

today. 

The Black Hills National Forest is annually one of the top timber‐producing forests in the 

National Forest System. The Black Hills have exhibited an outstanding ability to produce 
Vestal Final Environmental Impact Statement Chapter 3

169

ponderosa pine through natural regeneration (i.e., without tree planting), which allows 

sustainable timber harvest to continue at a relatively high rate. Consequently, many of the 

communities in and around the Black Hills are at least partially dependent on jobs and 

revenue generated by the local timber industry. 

Existing Conditions 

All data presented in this section was obtained from the U.S. Census Bureau website, 

www.census.gov . 

Population 

The Vestal project area is located in Custer County in southwestern South Dakota. 

Custer County is located within the southern portion of the Black Hills National Forest. 

Custer County is a rural setting which consists of approximately 48% public lands and 

52% private lands. The City of Custer (the County Seat) is the largest community within 

the county. Other smaller, surrounding communities include Pringle, Hermosa, Fairburn, 

and Buffalo Gap. 

Widespread settlement of the Black Hills by Euro-American settlers began in the 1870’s 

after gold was confirmed in the Black Hills by the Custer Expedition. Initially, 

settlement of the Black Hills was illegal as the area had been set aside for the indigenous 

Sioux Tribes. However, the lure of gold proved too great and prospectors engulfed the 

area and eventually led to the development of communities within the Black Hills. 

Following the initial ‘gold rush’, logging and ranching became the primary building 

blocks of the local economy in the early 20th century. Today the economy is much more 

diversified and recreation and tourism have emerged as large factors in drawing people 

into the area. Sub-development of private land within the Black Hills has led to 

increasing populations dispersed across the area rather than localized around the 

established population centers. Table 54 displays the population of Custer County using 

data from the 2000 & 2010 Census. 

Table 54. Area Population Based on 2000 and 2010 Census

Change

Custer County 7,275 8,216 +941 +12.9 % 

South Dakota 754,844 814,180 +59,336 +7.9 % 

Based on the data from the 2000 and 2010 Census, Custer County is growing at a faster 

rate than the State of South Dakota. Table 55 displays the ethnic background of Custer 

County compared to the State of South Dakota. 

 Table 55. Percent Population by Ethnicity Based on the 2010 Census

Origin or Race Custer County South Dakota

Caucasian 94.2 % 85.9 %

Native American or 

Alaska Native 2.9 % 8.8 % 

Hispanic 2.2 % 2.7 % 
Vestal Final Environmental Impact Statement Chapter 3

170

Asian 0.4 % 0.9 %

African American 0.2 % 1.3 % 

Pacific Islander 0 % 0 %

Custer County differs slightly from the State of South Dakota with the biggest difference 

being that Custer County has a higher proportion of Caucasian residents compared to the 

rest of the state. 

Economic Well-Being

Personal income, unemployment rate and poverty level are useful measures of economic 

well-being, or how well individuals and families are able to meet their basic needs for 

housing and subsistence as well as higher-level needs such as long-term financial stability 

and the ability to procure and enjoy luxury items. Economics ties to forest resources are 

integral to the economic well-being of many residents in the Black Hills. Some are 

engaged in the performance of vegetation management activities, such as timber harvest 

or grazing as a source of income. Others benefit economically from the recreation 

activities that occur on the forest as visitors to the area purchase gas, groceries, or 

recreational equipment from local retailers. Forest management proposals have the 

potential to impact economic prospects for these groups in varying ways. Table 56 

displays per capita income, unemployment rate, and poverty level for Custer County and 

South Dakota. 

Table 56. Economic Well-Being Based on 2006-2010 Census

Measure Custer County South Dakota

Per Capita Income

(in 2010 dollars) $24, 353 $24,110 

Median Household Income $46,743 $46,369 

Unemployment 2.4 % 6.0 % 

Persons Below Poverty 

Level 9.7 % 13.7 % 

Per capita income and median household income mirrors the state of South Dakota as a 

whole. Individuals below the poverty level are lower in Custer County compared to the 

state. Median home ownership values are greater in Custer County compared to the state. 

The unemployment rate is lower in Custer County than South Dakota as a state. 

Timber harvest has contributed greatly to the area’s economy. Early settlers used timber 

harvested from the Black Hills to construct buildings, railroads, and mining facilities. The 

very first timber sale on a national forest took place in 1898 near Nemo, South Dakota, 

which is now part of the Northern Hills Ranger District. Today, the Black Hills National 

Forest is one of the top timber‐producing forests in the National Forest System. This 

timber supply is a significant component of the support of local and regional 

communities, as well as contributing to the area’s supply of goods and services. Overall, 

the Black Hills National Forest’s practices have had a positive influence on the economy 

of the Black Hills area.

Three communities in the Black Hills region, Spearfish and Hill City, South Dakota and 

Hulett, Wyoming, are home to large lumber mills, all operated by a single owner, that 
Vestal Final Environmental Impact Statement Chapter 3

171

provide a significant number of jobs and are an important component of the local 

economy. Several smaller independent milling operations are scattered throughout the 

area. These mills rely on timber from the Black Hills National Forest to continue 

operations. 

Social Concerns

Several social concerns were raised during scoping: 

• Concerns were raised that the MPB risk would continue to be too high in the 

project area after proposed treatments are completed because some sites are 

deferred and/or treatments are not aggressive enough. Others question whether an 

epidemic is occurring within the project area and suggest that less aggressive 

treatments would be sufficient. 

• There was concern about the risk of wildfire to private property and access roads. 

• Concern was raised about impacts to Special Use Permittees that have 

campgrounds, roads, and trails within the project area. 

• There were concerns about the impacts of converting some non-system roads to 

system roads and the construction of a new access road to avoid private land and 

topography. There was also concern that thinning near closure gates would allow 

for motorized access behind the closed gates. 

• Concern was expressed that the proposed management actions may affect the 

scenic integrity of the project area as well as the stand level diversity for wildlife 

habitat.

• Concerns were raised regarding the level of timber harvest, with some 

commenters favoring less active management and some favoring more 

management.

• There were several commenters who expressed concern regarding the spread of 

noxious weeds as the result of management activities.

All of these resource related concerns have been addressed earlier in this EIS under the 

resource discussions. 

Environmental Consequences

The FEIS for the Revised Black Hills National Forest, Land and Resource Management 

Plan, Phase II Amendment (USDA, 2005a) included a social and economic analysis

(Sections 3-9 and 3-11). Such an analysis is done at the forest level because, in general, 

most projects don’t have social and economic effects large enough to be meaningfully 

measured. The Vestal project would be consistent with the Forest Plan and therefore, 

would contribute to the expected effects noted in the Phase II FEIS. None of the 

proposed activities within the Vestal project are anticipated to result in different social 

economic effects than those noted in the Phase II FEIS. 
Vestal Final Environmental Impact Statement Chapter 3

172

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 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). 

Please refer to the Silviculture and Soils sections in Chapter 3 for discussions related to 

short-term uses and long-term productivity. The proposed actions in this project include 

design criteria (see Appendix B) to protect soil productivity. These short-term actions 

would generally not damage or diminish long-term resource productivity. 

As provided for by the Forest Plan, minimum management requirements guide 

implementation of the action alternative. Adherence to these requirements ensures that 

long-term productivity of the land is not impaired by short-term uses. Monitoring 

specified in this EIS and the Forest Plan validates that the management requirements and 

mitigation are effective in protecting long-term productivity. 

Unavoidable Adverse Effects

The following is a description of adverse effects that are unavoidable with 

implementation of the action alternative. For further discussion of the effects on the 

resources listed below, see Chapter 3 under the respective resource topics. 

Forest Insect and Disease – will continue in the project area, at epidemic levels in some 

areas, and endemic levels in others. 

Wildlife Habitat – for certain species may be adversely affected to varying levels with 

implementation of the action alternatives. The Wildlife section of this EIS discloses 

those effects. 

Air Quality – may be adversely affected on a temporary/seasonal basis as a result of 

planned prescribed burning and dust from roads and activities. 

Scenic Quality – may be affected adversely for some observers by the various levels of 

vegetation treatment and other actions planned. 

Fire/Fuels Hazard – may be increased during the short-term in some areas as result of 

slash created from vegetation treatment. With disposal treatment this hazard will be 

reduced. There exists a higher long-term potential for large-scale wildfire under 

Alternative 1 versus Alternative 2. 

Soils – can be eroded wherever vegetation and soils are disturbed. Compaction can occur 

where vehicles and equipment are used. 

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 a temporary loss of timber productivity in 
Vestal Final Environmental Impact Statement Chapter 3

173

forested areas that are kept clear for use as a power line right-of-way or a road. For 

further discussion of the effects on resources, see the respective resource topics. 

There are no irreversible commitments of resources with any of the alternatives 

analyzed. 

There are no irretrievable commitments of resources under any alternative. 

Environmental Justice

Executive Order 12898 directs Federal agencies to focus attention on human health and 

environmental conditions in minority communities and low-income communities. The 

purpose of the executive order is to identify and address, as appropriate, 

disproportionately high and adverse human health or environmental effects on minority 

populations and low-income populations. 

In Phase II FEIS, Tables 3-59 and 3-60 highlight the demographic statistics for 

identifying potential communities of concern (USDA Forest Service 2005a). None of the 

counties in the study area contain low-income or minority populations as defined by 

Executive Order 12898. No additional outreach or analysis has been performed, as there 

would be no disproportionate negative effects on such communities under any of the 

alternatives. 

Additional evaluation of minority and low-income population data (USDA Forest Service 

2009a) show no evidence to suggest that the proposed action would have a 

disproportionate adverse effect on low-income populations. Evaluations also show that 

minority populations for the county in the study area are unlikely to meet the 

Environmental Justice criterion for a minority population and would be unlikely to 

experience disproportionate adverse effects from implementation of any alternative. 

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.” 

The project does not involve impounding or diverting water, or adverse impacts to 

threatened or endangered species, therefore, formal consultation with the U.S. Fish and 

Wildlife Service under the Fish and Wildlife Coordination Act is not required. 

No ground disturbing actions would occur in known eligible historical places. Section 

106 of the National Historic Preservation Act has been conducted as required and the 

State Historic Preservation Officer has concurred with a finding of no impact to eligible 

historic or prehistoric sites.

195

Provides service to large land areas and usually connects with public highways or 

other Forest arterial roads to form an integrated network of primary travel routes. 

The location and standard are often determined by a demand for maximum 

mobility and travel efficiency rather than specific resource management service. 

It is usually developed and operated for long-term land and resource management 

purposes and constant service. 

At-Risk-Community (ARC) 

An area (A) that is comprised of —(i) an interface community as defined in the 

notice entitled “Wildland Urban Interface Communities Within the Vicinity of 

Federal Lands That Are At High Risk From Wildfire” issued by the Secretary of 

Agriculture and the Secretary of the Interior in accordance with Title IV of the 

Department of the Interior and Related Agencies Appropriations Act, 2001 (114 

Stat. 1009) (updated 66 Fed. Reg. 43384, August 17, 2001); or (ii) a group of 

homes and other structures with basic infrastructure and services (such as utilities 

and collectively maintained transportation routes) within or adjacent to Federal 

land; (B) in which conditions are conducive to a large-scale wildland fire 

disturbance event; and (C) for which a significant threat to human life or property 

exists as a result of a wildland fire disturbance event.”

ground. The area is expressed in square feet per acre.

Best Management Practices (BMPs) 

Are methods, measures, or practices selected by an agency to meet its nonpoint 

source control needs. BMPs include but are not limited to structural and 

nonstructural controls, and operation and maintenance procedures. BMPs can be 

applied before, during and after pollution-producing activities to reduce or 

eliminate the introduction of pollutants into receiving waters (40 CRF 130.2(m)). 

An agreement between the USFS and the State of South Dakota stipulates that 

USFS Region 2 Watershed Conservation Practices (WCPs) will be used above 

and beyond South Dakota BMPs to comply with state and federal water quality 

regulations related to the Clean Water Act. 

Big Game 

Certain wildlife that may be hunted for sport under state laws and regulations. In 

the Black Hills, these animals include deer, elk, turkey, mountain goats, and 

bighorn sheep. 

Biological Evaluations 

As defined by FSM 2670.5, a biological evaluation is a documented Forest 

Service review of Forest Service programs or activities in sufficient detail to 

determine how an action or proposed action may affect any threatened, 

endangered, proposed, or sensitive species.

Collector Road 

Serves smaller land areas than a Forest arterial road and is usually connected to a 

Forest arterial or public highway. Collects traffic from Forest local roads and/or 

terminal facilities. The location and standard are influenced by both long-term 

multi-resource service needs, as well as travel efficiency. May be operated for 

either constant or intermittent service depending on land use and resource 

management objectives for the area served by the facility.

Ephemeral Streams 

A stream or portion of a stream that has flowing water only in direct response to 

precipitation in the immediate locality (watershed or catchment basin), and only 

flows during and for a short duration after the precipitation event. Runoff from 

rainfall or snowmelt is the primary source of water for stream flow. Groundwater 

is not a source of water for the stream and thus the stream bed is at all times above 

the water table. 

Erosion 

The wearing away of the land surface by running water, wind, ice, gravity, or 

other geological activities.

Erosion Hazard Rating 

The probability of soil loss from off-road and off-trail disturbance activities that

departure from natural fire, vegetation, and fuel regimes. 

• Fire Regime Condition Class I - Fire regimes are within natural range, and 

risk of losing key ecosystem components is low. Vegetation attributes 

(species composition and structure) are intact and functioning within historical 

range.
Vestal Final Environmental Impact Statement Chapter 5

from their natural range. The risk of losing key ecosystem components is 

moderate. Fire frequencies have departed from natural frequencies by one or 

more return intervals. Vegetation attributes have been moderately altered.

• Fire Regime Condition Class III - Fire regimes have been significantly 

altered from their natural range. The risk of losing key ecosystem 

components is high. Fire frequencies have departed from natural frequencies 

by several return intervals. Vegetation attributes have been significantly 

altered.

Fire Risk 

The chance of a fire starting, as affected by the nature and incidence of causative

agents, including lightning, people, and industry. Three risk scales are used: high, 

moderate, and low. High-risk areas include locations where lightning, people, or 

industry have commonly caused fire in the past; moderate-risk areas include 

locations where lightning, people, or industry have periodically caused fire in the 

past; and low-risk areas include locations where lightning, people, or industry 

have infrequently caused fire in the past.

Fire Suppression 

All the work and activities connected with fire-extinguishing operations 

beginning with discovery and continuing until the fire is completely extinguished. 

Fire Suppression Objective 

To suppress wildfires at minimum costs consistent with land and resource 

management objectives and fire-management direction as determined by National 

Fire Management Analysis System (NFMAS). This includes all work and 

activities associated with fire-extinguishing operations beginning with discovery 

and continuing until the fire is completely extinguished. 

Fireline Intensity

Numerically, it is the product of the heat combustion, quality of fuel consumed 

per unit area in the fire front, and the rate of spread of a fire as measured in BTUs 

per second per foot of the fire front. 

Floodplain 

The lowland and relatively flat areas adjacent to streams and standing bodies of 

water and coastal waters, including debris cones and flood-prone areas of offshore 

islands. 100-year floodplains include, at a minimum, the area subject to a 1% 

chance of flooding in any given year. 

Forage 

Vegetation used for food by wildlife, particularly ungulate wildlife and domestic 

livestock. 

Forbs 

Any herbaceous plant other than those in the grass, sedge, and rush families. For 

example, any non-grass-like plant that has little or no woody material.

Forest System Roads 
Vestal Final Environmental Impact Statement Chapter 5

200

Roads that are part of the Forest Development Transportation System that

includes all existing and planned roads as well as other special and terminal 

facilities designated as part of the Forest Development Transportation System. 

Fuel Breaks 

Generally wide strips of land 100-300 feet in width on which native vegetation 

has been modified so that fires burning into them can be more readily controlled. 

Some fuel breaks contain fire lines such as roads or hand lines that can be 

widened. 

Fuel Complex 

The combination of ground, surface, and canopy fuel strata. 

Fuel Loading 

The volume of the available or burnable fuels in a specified area, usually 

expressed in tons per acre.

Fuel Model 

A set of surface fuel bed characteristics (load and surface-area-to-volume-ratio by 

size class, heat content, and depth) organized for input to a fire model. Standard 

fuel models (Anderson 1982) have been stylized to represent specific fuel 

conditions. 

Fuel Treatment 

Any manipulation or removal of fuels to reduce the likelihood of ignition and/or 

to lessen potential damage and resistance to control, including lopping, chipping, 

crushing, piling, and burning (synonym for fuel modification). 

Fuels 

The organic materials that will support the start and spread of a fire: duff, litter, 

grass, weeds, forbs, brush, trees, and dead woody materials.

Goal 

Broad, general statement that encompasses the desired future conditions that the 

U.S. Forest Service seeks to attain.

Grass/Forb, Grass/Forb Stage (Structural Stage 1) 

(See Structural Stages - Structural Stage 1)

Guideline 

Preferred or advisable courses of action; deviations from guidelines are 

permissible, but the responsible official must document the reasons for the 

deviation. 

Hardwood 

Pertains to broadleaf trees.

Herbicide 

A chemical substance used for killing or suppressing plants.

Heritage Resources 

The physical remains (including but not limited to artifacts, structures, landscape 

modifications, rock art, trails, or roads) and conceptual content or context (as a 
Vestal Final Environmental Impact Statement Chapter 5

201

setting for legendary, historic, or prehistoric events, such as a sacred area for 

native peoples) of an area. 

Ignition (Fire Management) 

The initiation of combustion. 

Infrastructure 

The facilities, utilities, and transportation systems needed to meet public and 

administrative needs.

Insect Epidemic 

High population levels of insect pests that cause substantial injury to plant or 

animal hosts. Used synonymously with “Outbreak”. 

Intensity (Fire Management) 

How hot a fire is. Specifically, a measure (in BTUs per foot per second) of the 

energy released per unit of time in an area of actively burning fire. The amount of 

heat released per foot of fire front per second. 

Interdisciplinary Team (IDT) 

A group of individuals with different specialized training assembled to solve a 

problem or perform a task. The team is assembled out of recognition that no one 

discipline is sufficiently broad to adequately solve the problem. Through 

interaction, participants bring different points of view and a broader range of 

expertise to bear on the problem. 

Intermittent Stream

A stream or portion of a stream that flows, in its natural condition, only during 

certain times of the year when ground water provides water for streamflow. 

During dry periods intermittent streams may not have flowing water. Runoff from 

rainfall or snowmelt is a supplemental source of flow. 

Landscape Character 

Particular attributes, qualities, and traits of a landscape that give it an image and 

make it identifiable or unique. Valued landscape character creates a "sense of 

place" and describes the image of an area. The landscape character provides a 

reference for defining the inherent scenic attractiveness classes.

Late Succession 

Ecosystems distinguished by old trees and related structural features (Mehl, 

1992). This term encompasses the later stages of stand development that typically 

differ from earlier stages in structure, composition, function, and other attributes. 

There are two types of late-successional ponderosa pine defined for the Black 

Hills. The first type, open-canopy late-successional ponderosa pine, occurs where 

periodic, low-intensity fires have been part of the ecosystem. These latesuccessional stands would consist of clumps or groups of trees with grasses in the 

openings between the clumps. They would contain large old trees with open 

branches, irregular, and flattened crowns. The clumps or groups of trees would 

contain little down dead material and few small trees. The second type, closedcanopy late-successional ponderosa pine occurs where periodic, low intensity 

high-frequency fires have not been a significant part of the ecosystem. These 
Vestal Final Environmental Impact Statement Chapter 5

202

stands would contain large old trees with open branches and irregular crowns. The 

stands would have multiple canopy layers made up of various-aged trees. They 

would be well stocked with trees and contain standing dead and down trees.

located above the stream bed for most of the year. 

Piling and Burning 

Piling slash resulting from logging and subsequently burning individual piles. 

Plant Communities 

Assemblage of plant species living in an area. It is an organized unit to the extent 

that it has characteristics in addition to the individuals and populations and 

functions as a unit.

Riparian Area 

(See "Riparian Ecosystem.”)

Riparian Communities 

Repeating, classified, defined, and recognizable assemblages of plantor-animal 

communities associated with riparian areas.

Riparian Ecosystem 

The moist transition zone between the aquatic ecosystem and the relatively drier, 

more upland, terrestrial ecosystem(s). This transition zone can extend both 

laterally and longitudinally away from aquatic ecosystems, sometimes into 

headwater swales that have no defined stream channel. The riparian ecosystem is 

the area whose soil is relatively more moist than the adjacent upland and whose 

vegetation growth reflects the greater accumulation of available water.

Roads 

A general term denoting a way with at least two-wheel tracks for purposes of 

travel by vehicles greater than 50 inches in width. 

Sawtimber 

Trees suitable in size and quality for producing logs that can be processed into 

lumber. For planning purposes, trees with an 8-inch diameter or more are 

classified as sawtimber.

Scarify 

To abrade, scratch, or modify the surface of the ground to expose mineral soil (as 

in site preparation) or to break up compacted soil layers (as during road 

decommissioning or landing rehabilitation). 
Vestal Final Environmental Impact Statement Chapter 5

205

Scenery 

The composition of basic terrain, geologic features, water features, vegetative 

patterns, and landrise effects that typify a land unit and influence the visual appeal 

the unit may have for visitors.

Scenic Class 

Scenic classes measure the relative importance or value of discrete landscape 

areas having similar characteristics of scenic attractiveness and landscape 

visibility. Scenic classes are used during forest planning to compare the value of 

scenery with the value of other resources, such as timber, wildlife, late succession, 

or minerals. The higher the scenic class, the more important it is to maintain the 

highest scenic value. Scenic classes are determined and mapped by combining the 

three classes of scenic attractiveness with the distance zones and concern levels of 

landscape visibility. A numerical value of 1 to 7 is assigned to Forest lands. 

Generally, scenic classes 1-2 have high public value; classes 3-5 have moderate 

value; and classes 6 and 7 have low value. 

Scenic Integrity (Existing or Objective) 

State of naturalness or conversely the state of disturbance created by human 

activities or alteration. Integrity is stated in degrees of deviation from the existing 

landscape character in a national forest. It is the measure of the degree to which a 

landscape is visually perceived to be complete. The highest scenic integrity 

ratings are given to those landscapes that have little or no deviation from the 

character valued by constituents for its aesthetic appeal. Scenic integrity is used to 

describe an existing situation, standard for management, or desired future 

conditions. 

Very High: A scenic integrity level that generally provides for ecological change 

only. 

High: A scenic integrity level meaning human activities are not visually evident. 

In high scenic integrity areas, activities may only repeat attributes of form, line, 

color, and texture found in the existing landscape character.

Moderate: A scenic integrity level that refers to landscapes where the valued 

landscape character "appears slightly altered.” Noticeable deviations must remain 

visually subordinate to the landscape character being viewed. 

Low: A scenic integrity referring to the landscapes where the valued landscape 

character "appears moderately altered." Deviations begin to dominate the valued , 

being viewed, but they borrow valued attributes such as size, shape, effect, and 

pattern of natural opening, vegetative type changes, or architectural styles within 

or outside the landscape being viewed. They should not only appear as valued 

character outside the landscape being viewed but compatible or complimentary to 

the character within.

Very Low: A scenic integrity level that refers to landscapes where the valued 

landscape character "appears heavily altered.” Deviations may strongly dominate 

the valued landscape character. They may not borrow from valued attributes such 

as size, shape, edge effect, and pattern of natural openings, vegetative type 

changes, or architectural styles within or outside the landscape being viewed. 
Vestal Final Environmental Impact Statement Chapter 5

206

However, deviations must be shaped and blended with the natural terrain so that 

elements such as unnatural edges, roads, landings, and structures do not dominate 

the composition. 

Unacceptable Low: A scenic integrity level that refers to landscapes where the 

valued landscape character being viewed appears extremely altered. Deviations 

are extremely dominant and borrow little if any line, form, color, texture, pattern, 

or scale from the landscape character. Landscapes at this level of integrity need 

rehabilitation. This level should only be used to inventory existing integrity. It 

must not be used as a management objective.

Sediment 

Displaced soil material suspended in water or that has been deposited in streams 

and lakes.

Sensitive Species 

Those plant and animal species identified by the Regional Forester for which

population viability is a concern, as evidenced by significant current or predicted 

downward trends in population numbers or density; or significant current or 

predicted downward trends in habitat capability that would reduce a species' 

existing distribution.

Severely Burned Soil 

A condition in which most woody debris and the entire forest floor is consumed 

down to bare mineral soil. Soil may have turned red due to extreme heat. Also, 

fine roots and organic matter are charred in the upper one-half inch of mineral 

soil.

SHPO 

(See "State Historic Preservation Officer.”)

Silvicultural System 

A management process that tends, harvests, and replaces forests, resulting in a 

forest of distinctive form with a desired condition. 

Silviculture 

Generally, the science and art of tree management, based on the study of the life 

history and general characteristics of forest trees and stands, with particular 

reference to local factors; more particularly, the theory and practice of controlling 

the establishment, composition, constitution, and growth of forests for desired 

conditions. 

Site 

An area considered in terms of its physical and/or biological environment; for 

example, a riparian zone, a homogenous stand of vegetation, or a campground. 

Skid Trail 

Any way, more or less prepared, over which logs are dragged. Any road or trail 

leading from stump to landing. 

Skidding 

Moving logs from the stump to a collecting point.
Vestal Final Environmental Impact Statement Chapter 5

207

Slash 

The residue left on the ground after harvesting, sanitation operations, windstorm, 

or fire. It includes such material as unutilized logs, uprooted stumps, broken or 

uprooted stems, tops, branches, and leaves. 

Snag 

Standing dead tree or standing portion from which at least the leaves and smaller 

branches have fallen; often called a stub if it is less than 20 feet tall.

Soil Productivity 

The inherent capacity of a soil to support the growth of specified plants, plant 

communities, or a sequence of plant communities. Soil productivity may be 

expressed in terms of volume or weight/unit area/year, percent plant cover, or 

other measures of biomass accumulation. 

Standard 

Mandatory courses of action; any deviation from standards requires amendment 

of the LRMP.

Stand 

A community, particularly of trees, possessing sufficient uniformity as regards to 

vegetation type, age class, risk class, vigor, size class, and stocking class that

distinguishes it from adjacent communities and thus forms a management or 

silvicultural unity. Within a stand, a dominant or primary species and age class is 

identifiable, but there may be inclusions or clusters of different species or ages. 

R2 RIS stands are typically greater than 10 acres. IRI stands are typically greater 

than 5 acres.

Stand-replacing Fire 

A fire that kills all or most living overstory trees in a forest and initiates

secondary succession or regrowth. 

State Historic Preservation Officer (SHPO) 

A person appointed by a state's governor to administer the State Historic 

Preservation Program.

Stream Health 

The condition of a stream relative to robust health for that stream type and 

landscape, considering indicators such as channel pattern; slope; particle size; 

pool frequency and depth; bank vegetation; and woody debris that reflect the 

stability and habitat quality of the stream.

Stream Level 

A classification of the relative position of streams in a channel network. Firstlevel streams drain into the ocean. Second-level streams are tributaries to the 

first-level streams. For example, the Mississippi is a first-level stream; the 

Missouri is a second-level stream.

Structural Stages (Vegetation) 

Any of several developmental stages of tree stands described in terms of tree size 

and the extent of canopy closure they create. They include: 
Vestal Final Environmental Impact Statement Chapter 5

208

• Structural Stage 1 (Grass/Forb): An early forest successional stage during 

which grasses and forbs are the dominant vegetation. This stage is dominated 

by grasses and forbs lasting until tree seedlings become established. 

• Structural Stage 2 (Shrubs/Seedlings): Developmental stage dominated by 

tree seedlings (less than one inch dbh) and shrub species. This stage consists 

of shrubs and seedlings. This stage remains until seedlings reach 1 inch 

diameter at breast height (dbh).

• Structural Stage 3 (Sapling/Pole): Developmental stage dominated by young 

trees 1 to 9 inches dbh, 10 to 50 feet tall, and usually less than 50 years old. 

This stage is subdivided into three canopy closure classes: SS3A Sapling/Pole 

stage with less than 40% canopy cover

o SS3B Sapling/Pole stage with 40-70% canopy cover 

o SS3C Sapling/Pole stage greater than 70% canopy cover 

• Structural Stage 4 (Mature): Consists of trees larger and older than 

structural stage 3. This stage contains trees which are at least 9” dbh. 

o SS4A Mature stage with less than 40% canopy cover 

o SS4B Mature stage with 40-70% canopy cover 

o SS4C Mature stage greater than 70% canopy cover

• Structural Stage 5 (Late Succession): This stage is characterized by very 

large trees (16+ inches dbh). Trees are at least 160 years in age. Late 

succession ponderosa pine may occur in dense stands but may also grow in 

the open or in “park-like” stands. 

Successional Stages (Seral Stages) 

The relatively transitory communities that replace one another during 

development toward a potential natural community.

Temporary Roads 

A road developed and operated for a limited period of time that will cease to exist 

as a transportation facility after the purpose for which it was constructed is 

completed and the occupied land is reclaimed and managed for natural resource 

purposes. 

Thinning 

The practice of removing some of the trees in a stand to meet desired conditions. 

Two types of thinning may be done: 

Pre-commercial, Non-commercial: Removing trees that are too small to make a 

merchantable product. 

Commercial: Removing trees that have reached sufficient size to be 

manufactured into a product and to improve tree spacing and promote more rapid 

growth.

Threatened Species 

Any species likely to become endangered within the foreseeable future throughout 

all or a significant portion of its range and that has been designated in the Federal 

Register by the Secretary of Interior as such.
Vestal Final Environmental Impact Statement Chapter 5

(500 feet either side of the road's centerline) or 500 feet for major trails (250 feet 

either side of the trail's centerline); travel corridors form a passageway that allows 

travelers to experience and interact with the quality and character of the 

landscape.

Any or all natural resources, improvements, or other values that may be 

jeopardized if a fire occurs. 

Water Influence Zone (WIZ) 

The land next to water bodies where vegetation plays a major role in sustaining 

long-term integrity of aquatic systems. It includes the geomorphic floodplain 

(valley bottom), riparian ecosystem, and inner gorge. Its minimum horizontal 

width (from top of each bank) is 100 feet or the mean height of mature dominant 

late-seral vegetation, whichever is most. 

Watershed 

The area of land bounded by a divide that drains water, sediment, and dissolved 

materials to a common outlet at some point along a stream channel or to a lake, 

reservoir, or other body of water. Also called a drainage basin or catchment. 

Watershed Conservation Practices (WCPs)

Are stewardship actions based upon scientific principles and legal requirements to 

protect soil, aquatic and riparian resources. Each watershed conservation practice 

consists of a management measure, a set of design criteria used to achieve the 

management measure, and guidance for monitoring and restoration. 

Watershed Level

Vestal Final Environmental Impact Statement Chapter 5

210

“include essentially all surface waters such as navigable waters and their 

tributaries, all interstate waters and their tributaries, all wetlands adjacent to these 

waters, and all impoundments of these waters”. “Waters of the United States

Protection Agency (40 CFR 230.3), wetlands are those areas that are inundated or 

saturated by surface or ground water at a frequency and duration sufficient to 

support, and that under normal circumstances do support, a prevalence of 

vegetation typically adapted for life in saturated soil conditions. Wetlands 

generally include swamps, marshes, bogs, and similar areas. Wetlands are a 

subset of the “Waters of the United States” subject to regulation under Section 

404 of the Clean Water Act. 

Wildfire 

Any wildland fire not designated and managed as a prescribed fire within an 

approved prescription. All wildfires will be given an appropriate suppression 

action.
