APPENDIX C—RECLAMATION PLAN 

C.1 INTRODUCTION 

Reclamation of public land is required for any surface disturbing activity. A reclamation plan tailored to a 

specific surface disturbing activity will be required for Federal actions authorized, conducted, or funded 

by the Bureau of Land Management (BLM) and/or U.S. Forest Service (Forest Service) that disturb 

vegetation and/or the mineral/soil resources. This appendix details the elements that need to be considered 

during project planning, project implementation, and post-disturbance steps required to assure timely and 

proper recovery of the site. The reclamation processes included in this Appendix are specific to 

reclamation activities in sage-grouse core habitat areas proposed in this Resource Management Plan 

(RMP) and Land and Resource Management Plan (LRMP) amendment, hereafter land use plan (LUP) 

amendments. For reclamation requirements outside of core habitat areas, please refer to the Reclamation 

Plan in the appropriate BLM and/or Forest Service LUP. 

This plan provides a framework for project-specific and site-specific reclamation actions that guide land 

management toward a future condition for any surface disturbance in sage-grouse core habitat areas. 

Early coordination between the BLM and/or Forest Service and project proponents is necessary to 

produce a comprehensive, site specific plan. The site-specific reclamation plan will serve as a binding 

agreement between project proponents and the land management agencies for the expected reclamation 

condition of the disturbed lands and may be periodically reviewed and modified as necessary. The 

reclamation plan will include sufficient monitoring requirements, reports, and components to ensure 

sufficiency. 

Although the proponent will typically develop the reclamation plan, appropriate BLM and/or Forest 

Service involvement in preplanning, data inventory, and approval is essential to develop the optimum 

reclamation proposal. Most determinations regarding what is expected should be made before the 

reclamation plan is approved and implemented. However, the BLM and/or Forest Service 

Authorizing/Line Officer can modify a plan through adaptive management, to adjust to changing 

conditions or to correct for an oversight using the best available science; changes should be agreed upon 

by the project proponent. An approved reclamation plan and reporting obligations will be required prior to 

any surface disturbing activity. 

A reclamation plan has several purposes. For sage-grouse core habitat areas, the following will be used to 

guide the process: 

• Reclamation plans provide detailed guidelines for the reclamation process and fulfill federal, 

state, county, and other local agencies requirements. They can be used by regulatory agencies in 

their oversight roles to ensure that the reclamation measures are implemented, are appropriate for 

the site, and are environmentally sound. 

• Reclamation plans will be developed on a project specific basis; implementation of reclamation 

plans will be used by the project proponent throughout the permitting process, interim 

reclamation, cessation of surface disturbing activities (final reclamation), and finally at bond 

release (for energy development projects). In turn, the BLM and/or Forest Service will use the 

reclamation plan as a basis to review and evaluate the success of the reclamation program. 

• Reclamation plans should provide objectives and approved procedures to facilitate monitoring 

and compliance evaluations.

C.2 ECOLOGICAL SITE DESCRIPTION 

To understand the variations across the landscape, Natural Resource Conservation Service (NRCS) has 

classified these different parts into units called ecological sites. Ecological site is defined as “a distinctive 

kind of land with specific characteristics that differs from other kinds of land in its ability to produce a 

distinctive kind and amount of vegetation.” Any land inventory, analysis, and resulting management 

decisions require the knowledge of these individual sites and their interrelationships to one another on the 

landscape. 

The ESD application provides the capability to produce automated ESD from the data stored in its 

database. An ESD is the official repository for all data associated with the development of forestland and 

rangeland ESD by the NRCS. 

The data comprising an ESD is presented in four major categories: 

• Site Characteristics – Identifies the site and describes the physiographic, climate, soil, and water 

features associated with the site. 

• Plant Communities – Describes the ecological dynamics and the common plant communities 

comprising the various vegetation states of the site. The disturbances that cause a shift from one 

state to another are also described. 

• Site Interpretations – Interpretive information pertinent to the use and management of the site and 

its related resources. 

• Supporting Information – Provides information on sources of information and data utilized in 

developing the site description and the relationship of the site to other ecological sites. 

This information and the ESDs the NRCS have developed to date may be found at the following website: 

http://esis.sc.egov.usda.gov/Welcome/pgECOLOGICALSITEDESCRIPTIONWelcome.aspx

C.2.1 Reclamation Goals to Restore Sage-grouse Habitat Areas 

Goals: 

• Short term goal: immediately stabilize disturbed areas and provide conditions necessary to 

achieve the long term goal. 

• Long term goal: facilitate eventual ecosystem reconstruction to maintain a safe and stable 

landscape and meet the desired outcomes of the land use plan. 

• Reclaim vegetative communities within disturbed areas that will mirror those of healthy 

communities as described in the ESD. 

C.2.2 Reclamation Objectives in Sage-grouse Core Habitat Areas 

Objectives: 

• Restore vegetative cover and landforms sufficient to maintain healthy, biologically active topsoil; 

control erosion; and, minimize habitat loss during the life of the well, facilities, or other surface 

disturbing activities. 
Draft EIS Appendix C 

Wyoming Sage-grouse Land Use Plan Amendment C-3 

In addition: 

• Provide conditions and use methods to allow for successful reclamation in the least amount of 

time relative to site condition. 

• Accelerate the restoration of sage-grouse habitat components that may be outside of the project 

area to provide for sage-grouse population persistence in the area of disturbance. 

• Return the land to the desired condition based on ESDs. This includes restoration of the landform 

and natural vegetative community, hydrologic systems, visual resources, and wildlife habitats. To 

ensure that the long-term objective will be reached through human and natural processes, actions 

will be taken to ensure standards are met for site stability, visual quality, hydrological function, 

vegetative productivity, and habitat function. 

C.2.3 Pre-Disturbance Baseline Inventory 

Pre-disturbance inventory is a critical part of reclamation planning and provides information on 

ecological structure and function. This should include inventory of wildlife habitat, species composition, 

watershed protection, and visual qualities; as well as, characteristics that underlie those values and 

functions – the plants, soil, and landscape features that may require restoration. The inventory establishes 

a framework for successful reclamation, monitoring, and evaluation (Norton et al. 2010). 

The inventory includes two steps necessary to compile complete and accurate information: 

1. Gathering existing site-specific information from reliable sources; and, 

2. Evaluating on-site ecosystem function and characteristics that may require subsequent 

restoration (Norton et al. 2010). 

Table C-1. Description of Baseline Inventory 

Activity Critical Components

Initiating baseline inventory

• Identify site location

• Contact land manager/owner or agency

C-4 Wyoming Sage-grouse Land Use Plan Amendment 

C.2.4 Reclamation Plan Requirements/Minimum Standards 

Reclamation plans should incorporate the standards set forth in Wyoming BLM Reclamation Policy as 

described in IM WY-2009-022 and in the corresponding Forest Service Manual / Handbook In the future, 

this will be supported with more detailed guidance such as new reclamation bond standards, a statewide 

monitoring and reporting strategy, and sample templates for both reclamation and non-native and invasive 

species management plans. Specific reclamation information and other technical guidance will be 

forthcoming and posted on the Wyoming Reclamation web site 

(http://www.blm.gov/wy.st/en/programs/reclamation.html).

C.2.5 Reclamation Best Management Practices for Sage-grouse 

Habitat 

Habitat reclamation will be initiated, and subsequently supplemented as necessary, to meet reclamation 

standards within all areas of sage-grouse habitats affected by soil disturbing activities.

Vegetation Management 

• Avoid disturbance in areas providing the best attributes for sage-grouse nesting, brood rearing, 

and wintering habitat (i.e., dense stands of sagebrush) when siting the location of a proposed 

action. 

• Reduce vegetation damage during reclamation in adjacent areas of sage habitats. 

• Choose native seed mixes that will provide a height to cover ration to provide the maximum 

nesting cover. Where native seed mixes of local genotype are not available, consider the use of 

appropriate cultivars of native species. 

• Plan time of year for seed planting based on the optimal growing conditions for that species, site 

specific conditions, and the environmental conditions of that growing season. 

• Reference the Upper Green River and Sage-grouse Working Group Beneficial Seed Matrix for 

Sage-grouse, Mule Deer and Antelope: 

– http://gf.state.wy.us/wildlife/wildlife_management/sagegrouse/UpperGreenRiver/Index.asp 

– http://gf.state.wy.us/wildlife/wildlife_management/sagegrouse/Northeast/index.asp 

• Species used solely for site stabilization should be sterile, or a species unlikely to persist as 

natives are established. 

• The land management agencies do not recommend using a cover crop in areas with precipitation 

less than ten inches, as some cover crop species are not recommended for use in areas below 12 

inch precipitation; local land management agencies, the NRCS, or other experts should be 

consulted for site-specific recommendations on cover crop species. 

Additional Monitoring Components 

Project proponent should start post-disturbance collection of cover and composition data in the first 

growing season after disturbance. Data must be collected using repeatable methods approved by the 

appropriate land management agency and will be the same methods that were used to describe vegetation 

for baseline (or reference area). The same methods will be used each time the vegetation is monitored. 
Draft EIS Appendix C 

Wyoming Sage-grouse Land Use Plan Amendment C-5 

Pre-Development Habitat Management 

Use native site seed collection and local seed sources to the maximum extent practicable to maintain 

genetic diversity of local plant populations. Consider the use of cultivars of native species in the absence 

of sources of native seeds.

Exceptions 

To facilitate reclamation seeding during the optimal growing seasons, exceptions may be approved 

providing that the exception granted would minimize surface disturbance outside of the action area. 

Proponent Agreements 

The land management agencies will encourage cooperative agreements between the agencies, proponent 

project proponents, and interested proponents so as to ensure the success of habitat reclamation. 

C.2.6 Criteria for Determining Reclamation Success 

The end result of reclamation success is the return of functional wildlife habitat (particularly to meet the 

sage-grouse each of the life stage requirements) within the disturbance area, as well as limiting the 

density of disturbance within the project impact analysis area (PIAA). By meeting the reclamation criteria 

below, a disturbance area would no longer count toward five percent loss of sage-grouse habitat in the 

density of disturbance calculations conducted by the BLM and Wyoming Game and Fish Department 

(WGFD). 

A. The recently released Rangeland Ecological Site Interagency Manual (WO IB 2011-004) has the 

following objectives that address the use of ESD which include State and Transition Models: 

• To implement a standardized system to define and describe a common unit for inventory, 

monitoring, evaluation, and management of rangeland ecosystems. 

• To provide direction for the cooperative development and application of rangeland ESD. 

B. The Rangeland Ecological Site Interagency Handbook (mentioned above) goes into detail on use of 

State and Transition Models and ESD, and can be used as a reference when developing reclamation plans 

using these methods. 

C. The current BLM Handbook H-4180-1 contains references to ecological sites, ESD, and reference 

areas. The site potential is related to transitions and thresholds in the handbook. The handbook also 

recognizes the Ecological Site Index and ESD may not be available for all assessment areas, but that 

where they exist, they should be used. Other vegetation succession models are not mentioned in H-4180-

1.

D. The National Range Handbook (H-4410-1) addresses State and Transition Models and ESD and can be 

used as a reference. 

E. The NCRS Ecological Site Inventory Technical Reference (TR 1734-07) also discusses about 

succession and State and Transition Model pathways, and ESD. 

F. The NRCS Riparian-Wetland Ecological Site Inventory Technical Reference (TR-1737-7) does the 

same. 
Appendix C Draft EIS 

C-6 Wyoming Sage-grouse Land Use Plan Amendment 

If ESDs, which include State and Transition Models, are not written for the project site, the project 

proponent should work with the land management agencies, WGFD, NRCS, and other local experts to 

create these products. 

Sage-grouse Habitat Requirements 

Vegetative Criteria 

Native Forbs: The average frequency of desirable forbs must be a minimum of 75 percent of the ESD 

reference site. Reference sites must be selected in areas of the same ESD and must be mutually agreed 

upon with the land management agency and WGFD. If this is not possible, the desired plant community 

for the site may be used. Diversity of forbs on a reclaimed site must be equal to or greater than predisturbance composition. Timeframes to determine whether replanting or developing another strategy to 

meet native forb establishment will be determined upon establishing the ESD model. 

Native Shrubs: The average frequency of the shrub component must be at least 50 percent of the ESD 

reference site. This includes both shrubs and sub-shrubs (e.g., winterfat (Scientific name), fringed sage 

(Scientific name), etc.). At least 15 percent density or frequency of the shrub component must be by the 

dominant species relative to pre-disturbance composition. The diversity of shrubs must be equal to or 

greater than the desired plant community. Timeframes to determine whether replanting or developing 

another strategy to meet native shrub establishment will be determined upon establishing the ESD model. 

Native Grasses: Reclaimed sites must have growth forms and plant diversity representative of the ESD 

reference site. These are to be planted at rates appropriate to achieve abundance and diversity 

characteristic of those found in the ESD reference site. Timeframes to determine whether replanting or 

developing another strategy to meet native grass establishment will be determined upon establishing the 

ESD model. 

Non-Native and Invasive Species: Reclaimed sites must be free from all species listed on the Wyoming 

Noxious Weed List. All local, state, and federal invasive1

 plant laws and regulations must be adhered to. 

Other highly competitive invasive plants, such as downy brome grass, will be controlled. Site specific 

weed management plans will address management goals and priorities. 

Plant Vigor: Plants must be resilient as evidenced by well-developed root systems, flowers, and seed 

heads. All sites to be considered reclaimed must exhibit the sustainability of the above desired attributes. 

A minimum of one growing season without external influences (irrigation, mat pads, fences, etc.) may

satisfy this requirement. 

Final Reclamation Criteria 

Ground Cover and Ecological Function 

To ensure soil stability and nutrient cycling, canopy must be equal to or greater than the pre-disturbance 

composition and vegetative litter must be decomposing into the soil. 

Vegetative Criteria 

Native Forbs: The average percent composition and total diversity of forbs must be equal to or greater 

than pre-disturbance composition. Timeframes to determine whether replanting or developing another 

strategy to meet native forb establishment will be determined upon establishing the ESD model. 

 

1 Invasive species. A species that is not native (or is alien) to the ecosystem under consideration and whose introduction causes 

or is likely to cause economic or environmental harm or harm to human health (Executive Order 13112). 
Draft EIS Appendix C 

Wyoming Sage-grouse Land Use Plan Amendment C-7 

Native Shrubs: The average frequency of the shrub component must be at least 80 percent of predisturbance composition within eight years. This includes both shrubs and half shrubs (e.g. winterfat, 

fringed sage, etc.). At least 25 percent density or frequency of the shrub component must be the dominant 

species from the reference site. The diversity of shrubs must be equal to or greater than the reference site. 

Native Grasses: Reclaimed sites must exhibit grass percent composition equal to the reference site. 

Timeframes to determine whether replanting or developing another strategy to meet native grass 

establishment will be determined upon establishing the ESD model. 

Non-Native/Noxious/Invasive Weeds: Sites must be free from all species listed on the Wyoming and 

Federal noxious weed list. All state and federal laws regarding non-native species and noxious weeds 

must be followed. Aggressive action to eliminate highly competitive invasive species such as cheatgrass 

and other invasive brome grasses must be taken to prevent spread. 

Plant Vigor: Plants must be resilient as evidenced by well-developed root systems and flowers. Shrubs 

will be well established and will exhibit age class structure. 

An Alternative Determination for Reclamation Success 

Standards for success will be developed based on performance based criteria and the ESD. Locations 

where the site provides sage-grouse habitat during all life stages; will have criteria developed based on 

habitat requirements for sage-grouse. Criteria may be developed based on the nesting, early and late 

brood-rearing, and winter concentration habitats. If the site has insufficient soil attributes or other 

components to provide sage-grouse habitat based and the ESD confirms that you will never have 

attributes that provide for sage-grouse habitat, the reclamation can be deemed a success as long as it 

meets the ESD. The objectives for each reclamation plan are set with site specific criteria at the field 

office level, thereby maximizing the unique conditions within each field office. 

C.2.7 Monitoring 

1. Standard Monitoring Requirements: 

a. Project proponents must use the same locations and methods used at baseline for repeat 

photography. Additional locations may be selected to document progress of reclaimed 

area to demonstrate interim2 and final reclamation3 success, and to monitor any identified 

problems such as erosional features. The site should be photographed once every year 

normally at the same time period, from the same locations and direction so that 

photographs are repeated through time. Photographs should be taken during the growing 

season. 

b. Weed inventory: Disturbed and reclaimed areas will be evaluated for noxious and 

invasive weeds annually until the timeline determined by the ESD model has been 

satisfied. A weed control plan will be written separately under the BLM and/or Forest 

Service’s Integrated Weed Management Program. 

c. Erosion control/soil stability: The reclaimed area should be evaluated for any signs of 

erosion problems annually (until the timeline determined by the ESD model has been 

 

2 Interim reclamation may proceed if a project will be dormant for an undetermined amount of time, to provide cover to prevent 

erosion events and to provide forage for wildlife). 

3 Final reclamation occurs when all activities on the location have been completed, recontouring occurs and the seed mix 

contains all species necessary for habitat recovery. 
Appendix C Draft EIS 

C-8 Wyoming Sage-grouse Land Use Plan Amendment 

satisfied) and when the site is subject to erosional events. Identified erosion features 

should be monitored using repeat photography. Absence of erosion features is a positive 

indication that the soil is stabilizing. 

d. Hydrological function measurements should be documented using Technical Note #346 

Erosion condition classification system and the determination of erosion condition class 

sheet to ensure the of erosion control methods worked during the development phase and 

the final pad contouring; resulting in the return of the original hydrologic function of the 

site. 

e. Restoration of the landforms visual resource should also be documented, whether 

returning the location to the original visual classification under the LUP or the original 

topographic features. 

f. Wildlife habitat communities should be monitored to ensure that the goals for sensitive 

wildlife species are also being met. The following tools may be used to include 

parameters that may not be necessary in the ESD but are useful in documenting wildlife 

habitat potential: 

– Important Wildlife Habitats: http://gf.state.wy.us/downloads/pdf/og.pdf 

– Sage-grouse range wide forum links: http://sagegrouse.ecr.gov/?link=110 

– Recommendations for Development of Oil and Gas Resources within Big Game Crucial and 

Important Habitats: http://gf.state.wy.us/downloads/doc/O&G%20Recommendations%20 

April%202010%20with%20changes%20identified.pdf 

2. Reclamation actions will be initiated before the first growing season following disturbance. 

3. Following each growing season: 

a. Review and complete a site-specific vegetation monitoring report for areas being reclaimed. 

b. Prepare a written, site-specific prescription for actions to be implemented, including: 

– Reseeding of areas not attaining reclamation success 

– Soil stabilization 

– Weed control needs 

– Mulching/fertilization or other cultural practices prescribed for the following season. 

4. If the treatment area is found, through site-specific monitoring data, to be successfully reclaimed, 

monitoring to confirm reclamation success will continue until the timeline determined by the ESD model 

has been satisfied. The site will also comply with additional management needs, including control of 

weed infestations. 

5. Within one to three years of initiation of reclamation, sites will demonstrate the establishment of a 

viable desirable seedling frequency. (Pro-action may want to be taken if reclamation is not successful 

during a good moisture year.) Desirable seedling density or frequency, compared to pre-disturbance 

composition information, shall consist of a vigorous, diverse, native (or otherwise approved) plant 

community or ecologically comparable species as approved by BLM and/or Forest Service’s 

Authorizing/Line Officer (AO). If this does not occur the project proponent should coordinate with the 

BLM, Forest Service, NRCS, WGFD, or other local experts to determine an alternative course of action to 
Draft EIS Appendix C 

Wyoming Sage-grouse Land Use Plan Amendment C-9 

ensure full site recovery, the actions prescribed will be implemented as planned and further monitoring 

will occur as detailed beginning with the first action listed above. 

If at any time pre-disturbance composition data is not suitable for reclamation success determinations, the 

project proponent may select a desired plant community in the reference state from the ESD State and 

Transition model. 

C.2.8 Reporting 

The project proponent will provide the BLM and/or Forest Service’s with an annual report for all sites 

disturbed. The report will include: 

• Copies of the completed individual site review forms or a BLM and/or Forest Service-approved 

electronic report. 

• A summary of monitoring data and results, including: 

– Individual site reclamation monitoring reporting data (Table A36-1) 

– Identification of sites successfully reclaimed by reclamation years (starting with the first 

growing season) 

– Identification of sites needing additional work or more reclamation activities (adaptive 

management) by reclamation year 

– Sites proposed for the end of monitoring (i.e., sites that were successfully reclaimed). 

• The BLM and/or Forest Service’s useable shape file(s) or geographic information system (GIS) 

layer(s) that details location, name, type, and extent of: 

– New disturbances 

– Unreclaimed disturbance 

– New reclamation 

– Failed or unsuccessful reclamation 

– Locations of noxious/invasive weed infestation 

– Further vegetation treatments planned (e.g., mulching, matting, and weed control). 

On these shape files or GIS layers, location shall be given as the legal location and geo-referenced 

location of the site; name, as appears on the BLM and/or Forest Service’s Application for Permit to Drill 

(APD), lease, or other BLM and/or Forest Service file name for the site; extent, as the appropriate 

component boundary.

ATTACHMENT A—RECOMMENDED RECLAMATION 

PRACTICES FOR ENSURING SUCCESSFUL AND 

TIMELY ECOSYSTEM RECLAMATION IN SAGEGROUSE HABITAT 

RECOMMENDED BEST MANAGEMENT PRACTICES FOR HANDLING 

SUITABLE SOILS TO MAINTAIN SOIL QUALITY

SUGGESTIONS ON STOCKPILING SUITABLE AND UNSUITABLE SOILS TO MAINTAIN 

SOIL QUALITY

The methods suggested in this section have been documented to improve reclamation success; however it 

is up to the project proponent to utilize their judgment, expertise, and the latest research and information 

to achieve desired results. 

Stockpiled topsoil should not be piled too deeply or too shallow. The taller or deeper the piles the more 

soil is buried under large amounts of pressure resulting in compaction. Soil buried deep in the pile also 

has little exposure to oxygen resulting in anaerobiosis; deeply buried soil also has no organic matter input. 

Both of these problems reduce soil quality. 

Shallow or small topsoil stockpiles have large footprints on the land surface with the disadvantage of 

covering greater areas of undisturbed soil which will, in turn, require revegetation, resulting in a greater 

overall amount of disturbed soil. Smaller or shallow stockpiles also have a greater surface area per 

amount of soil stored which increases exposure of the stockpiled soil to wind and water erosion. The 

surface of soil stockpiles should always be vegetated to minimize erosion losses. 

• Salvaged stockpiles of suitable soil should be no deeper than four meters (13 feet) and should be 

less where possible with the understanding that greater surface disturbance may occur. 

• Stockpile slopes should not exceed 5:1 angles (20% slopes) to allow for seeding and minimize 

erosion. 

• Suitable soil stockpiles should be located in areas to prevent their disturbance and contamination 

by project activities. They should not be placed in streambeds or ephemeral drainages where they 

may be washed away. They should be protected from wind erosion. 

• A perimeter ditch/berm can be constructed around the stockpile for topsoil conservation and 

sediment control where necessary. 

• All suitable soil stockpiles should be seeded with native cool season grass to provide cover and 

protect them from water and wind erosion. Before seeding, the stockpile may be scarified along 

contours to minimize wind and water erosion. 

• If soil horizons or layers are to be stratified during soil salvage (stripping) operations, soil maps 

should be made of the well pad area to identify depths of soil horizons and surface slope. The 

area to be cleared of soils should then be divided into strips the size of the blades or equipment 

being used for soil removal. The depth of soil removal from each swath should be clearly marked 
Appendix C Draft EIS 

C-14 Wyoming Sage-grouse Land Use Plan Amendment 

so that equipment operators are removing a uniform layer from each strip. After the topsoil is 

removed from the area in this manner, the subsoil can then be removed in the same fashion, strip 

by strip, each strip at a uniform depth. 

SOIL AMENDMENTS

• Soil amendment(s) may be used in reclamation if the soil is lacking the necessary chemical, 

biological, physical and /or organic materials to support sustaining growth of suitable plant 

materials. The soil type, soil characteristics, geographic location, along with soil mapping 

resources available should provide the information necessary to define the soil amendment. 

• The Project Proponent should state what applying soil amendments is intended to accomplish. 

Soil amendment plans should be provided, including what amendments will be applied, method 

of application, and timing relative to other reclamation activities (i.e. stockpiling, seeding, 

ripping). 

• The soil type is defined by the soil samples obtained prior to, or in some cases, after disturbance 

takes place. Soil amendments must be scientifically calculated based on the soil characteristics so 

as to provide the most cost efficient and best assurances for successful reclamation. 

• Soil amendments include but are not limited to the following: Weed free grass hay, weed free 

wood chips or other weed free cellulosic materials, gypsum, elemental sulfur, and fertilizer. 

SUGGESTIONS ON VEGETATION AND SOIL MONITORING

Examples of monitoring components are listed below: 

• Reference: http://agriculture.wy.gov/forms/natres/rangelandmonitoring.pdf 

SUITABLE SOIL INVENTORY

• Soil characteristics may strongly influence reclamation efforts. Fundamental characterization of 

soils ahead of disturbance can identify potential problems, so they can be addressed during 

disturbance, soil stockpiling and reclamation, instead of waiting for reclamation failure. 

• The phrase “suitable soil” is used mainly because of confusion over the definition of topsoil. Soil 

depth, pH, electrical conductivity, texture, surface features (e.g. barren, rocky, crusty, plant litter), 

and organic matter content are characteristics that may be used to determine if a soil is suitable. 

Other information may be needed. See: “Successful restoration of severely disturbed lands: 

Overview of critical components,” B-1202, (and available for free at 

http://ces.uwyo.edu/PUBS/B1202.pdf.). 

• Soil characteristics that can signal a high probability of reclamation problems include: pH, 

electrical conductivity, soil texture, surface/subsurface features, sodium adsorption ratio, calcium 

carbonate content, soil compaction, and saturation percentage. The listed characteristics below 

will be addressed by the Proponent in the site specific reclamation plan approved by the BLM 

and/or Forest Service. 
Draft EIS Appendix C 

Wyoming Sage-grouse Land Use Plan Amendment C-15

– Soils with pH 7.8 and higher progressively become less suitable for reclamation and will be 

addressed by the Operator in the site specific reclamation approved by the BLM and/or Forest 

Service. 

– An electrical conductivity of soil greater than eight deciSiemens per meter (dS/m) and any 

increase in salt content of the soil above 0.5 dS/m will progressively negatively affect the 

establishment and growth of plants. Soils exhibiting these characteristics will be addressed by 

the Operator in the site specific reclamation plan approved by the BLM and/or Forest Service. 

– Soils with textures representing clay, sand or loamy sand will be addressed by the Operator in 

the site specific reclamation plan approved by the BLM and/or Forest Service. 

– Surface and subsurface soil in and through the root zone dominated by coarse material greater 

than two millimeters in diameter and greater than 40 percent in the soil profile to be 

stockpiled may signify reclamation difficulties and will be considered in the site specific 

reclamation plan by the BLM and/or Forest Service and Proponent. 

– Sodium adsorption ratio (SAR) is a key diagnostic soil trait that may be determined for soils 

to be disturbed and placed in the suitable soil stockpile; and will be addressed by the Operator 

in the site specific reclamation plan approved by the BLM and/or Forest Service. 

– Calcium carbonate content (percent lime) will control the amount of plant available 

phosphorus and will determined in the site specific reclamation plan by the Operator and 

approved by the BLM and/or Forest Service. 

– The soil saturation percentage will control the ability for plants to germinate and survive after 

reclamation actions have been taken by the Operator and will be addressed by the Operator in 

the site specific reclamation plan approved by the BLM and/or Forest Service. 

SITE PREPARATION 

It is important to consider diversity in seedbed preparation to account for various seed sizes and 

establishment strategies of different species. Consideration should be given for seed-safe sites, water 

infiltration and collection, shade, and frost protection. 

RECONTOURING 

Trees, shrubs, and ground cover adjacent to disturbance areas but not cleared from rights-of-way (ROW) 

require protection from construction damage. Recontouring to preconstruction condition as well as 

restoration of normal surface drainage is required. 

ROAD RECLAMATION GUIDELINES 

Road reclamation guidelines are as follows: 

• Determine the desired level of obliteration and reclamation. Determine whether there are 

alternative short- or long-term uses for roads. 

• Determine short- and long-term reclamation objectives and goals. Identify the monitoring 

methods to determine reclamation success or failure and possible mitigation. 

• Reclaim the road; the effort may include ripping and scarifying the surface, removing culverts 

and other flow structures, recontouring cut and fill slopes to provide for complete removal of the 

road, and total recontouring to the original topographic profile. 

• Reclaim vegetation to standards outlined in the section on “criteria for reclamation.” 
Appendix C Draft EIS 

C-16 Wyoming Sage-grouse Land Use Plan Amendment 

• Establish mitigation measures to remedy problems identified by monitoring. 

NON-NATIVE AND INVASIVE SPECIES 

One of the land management agencies’ highest priorities is to promote ecosystem health, and one of the 

larger obstacles to achieving this goal is the rapid expansion of non-native and invasive species across 

public lands. Invasive plants can dominate sites and often cause long-term changes to native plant 

communities. If not eradicated or controlled, invasive species will jeopardize the success of reclamation. 

Invasive species can slow reclamation success or halt it altogether. Right-of-Way (ROW), mineral lease, 

mining claim, and permit holders are required to monitor and control invasive species on public land as 

stipulated within their permits and authorizations. 

INVASIVE PLANT MANAGEMENT PLAN FOR CONSTRUCTION AND 

RECLAMATION ACTIVITIES

Disturbed sites can provide ideal opportunities for invasive plant species to propagate. Invasive plants can 

be transferred to the disturbed site from adjoining areas and out-compete desired vegetation during 

reclamation and/or spread to new areas. The best approach to combat invasive species is to use careful 

suitable soil handling and an appropriate seed mix. Pre-disturbance planning, including early weed 

management for invasive species is vital to reduce costs and ensure successful reclamation. 

• Assess for noxious and invasive weed species before initiating surface disturbing activities, 

during disturbance, during interim and final reclamation, and after reclamation is completed. 

• Web address for the Wyoming Weed and Pest Council: http://www.wyoweed.org/. 

• Apply invasive species control treatments. 

– Consider clipping or shredding invasive plants to prevent re-seeding or nuisance to neighbors, 

when developing control treatments (NRCS 2001). 

• Monitor invasive plant species at least annually to evaluate success of control treatments and 

determine if continued treatment is necessary. 

The vegetation will consist of species included in the seed mix and/or occurring in the surrounding natural 

vegetation or as deemed desirable by land management agencies in review and approval of the 

reclamation plan. No single species will account for more than 30 percent total vegetative composition 

unless it is evident at higher levels in the adjacent landscape. Vegetation canopy cover production and 

species diversity shall approximate the surrounding undisturbed area. 

SEED 

On all areas to be reclaimed, seed mixtures are required to be weed free and site specific, composed of the 

same native species as determined in the Desired Plant Community/ESD or early successional species 

consisting of pioneer species, including seasonal or annual species (that may only be evident at certain 

times of the year), that will lead to a similar climax community as that disturbed. Site preparation and 

species choices must ensure soil stability. 

A Desired Plant Community/ESD species composition list must be developed for each site to ensure 

proper community composition, function, and structure. This will ensure that the type of vegetative

Wyoming Sage-grouse Land Use Plan Amendment C-17

community replaced is compatible with climate and soil types and should make it easier for the project 

proponent to successfully restore and stabilize specific sites. 

Livestock palatability and wildlife habitat needs should be given consideration in seed mix formulation 

during reclamation within areas of important wildlife habitat (crucial winter range, sage-grouse nesting 

habitat, etc.); provision shall be made for the replacement of native browse and forb species. Bureau of 

Land Management guidance for native seed use is the BLM Manual 1745 and Executive Order (E.O.) 

13112 (Invasive Species, 64 Code of Federal Regulations [CFR] 6183). In addition, specific seed mix 

recommendations appropriate to restore sage-grouse habitats are included at the end of this Appendix 

from the NE and Upper Green River Sage-grouse Working Groups. 

DESCRIBE SEEDING METHODS

• Different plant species may require different conditions (e.g. seeding depth, seed scarification, 

mixing, and timing) for optimal germination success. Seeding methods should match germination 

characteristics of species in the seed mix and consider timing of planting to maximize 

germination and establishment of all reclamation species. 

• The Proponent will describe when seeding will occur and specify the methods they will use for 

seeding, including differential handling for different species (e.g. broadcast vs. drilling vs. 

imprinting), and seeding depth in the site specific reclamation plan. Re-seeding may need to 

occur if invasive and/or noxious weeds prevent establishment of the seed mix. 

A germination test is recommended to be conducted to determine the productivity of the site and the seed 

purchased. 

Germination Test 

A germination test samples for total viability, including the sum of all seeds (of a “kind” listed on the 

label) actually germinating using standard laboratory methods + hard seed and/or dormant seed. 

Percent Germination: A germination test determines the capability of a seed lot to produce normal 

seedlings under favorable controlled conditions. Total germination is the percent germination added to the 

percent hard and/or dormant seed. Anything under 100 percent total germination represents the presence 

of dead seed and/or seed that doesn’t produce a shoot or root. Germination may also be estimated by the 

use of a tetrazolium chloride test (TZ test) in which seeds are stained with a dye to determine viability. 

Viable seed with live (respirating) tissues will stain a red color. However, not all states recognize the use 

of a TZ test for all species.

Dormant Seed: Includes hard seed, refers to the portion of the seed sample that doesn’t germinate during 

the seed test. Reasons for dormant seed are: 1) the seed coat is impervious to water, and/or 2) internal 

structures within the seed prohibit oxygen exchange. Hard seed may germinate at a later date and produce 

a viable plant, or it may germinate and succumb to competition, or it may never germinate at all. 

The higher the germination percentage, the better. Germination of most grass species is normally above 

80 percent and should not be lower than 60 percent. Germination of some native grasses, forbs, and 

shrubs may be lower, but can vary widely according to species. 

The germination test date should also be current. Grass, forb and legume seed should be updated every 

nine to 18 months depending on state laws. Flower, shrub, and tree seed should be updated every nine 

months.

STANDARD SEED MIXTURES 

Care and planning must be taken to choose mixes and amounts that will benefit under site-specific 

conditions. Planning and thought must also go into selecting successful planting and site-preparation 

techniques. All sites must be planted with a diverse mix of grasses, forbs, and shrubs to be considered 

successful. The project proponent is ultimately responsible for successful restoration of disturbed sites. 

Seed mixes should be based on and the Desired Plant Community that is achievable according to the 

ESD. When appropriate native plant materials are not commercially available, use of local collections or 

adapted species that perform similar function may be used in lieu of the exact species described the ESD 

that has been shown to be successful in previous trials. Return of cover should be gauged by comparison 

with actual pre-disturbance site conditions and/or reference areas. Alternate seed mixes can be submitted 

by the project proponent to the BLM and/or Forest Service for review and approval prior to use. The final 

goal is to restore disturbed sites so that they closely resemble predisturbance native plant communities. 

Some standard seed mixes are available for the Field Office and contain only native species. If the use of 

a non-native species is desired, documentation of the need is required by the BLM and/or Forest Service 

policy. Non-native species may be considered for erosion and weed control. Seed mixtures consisting of 

sterile annual cover crops, such as tricale hybrid, can be used. The use of a non-sterile plant species such 

as wheat as a cover crop is not recommended because of its ability to reseed itself. Follow-up seeding or 

corrective erosion control measures will be required on areas of surface disturbance that fail to meet 

reclamation success standards within a reasonable time. 

SEED MIXES

The need to provide multifunctional and sustainable seed mixes for interim and final reclamation and soil 

stability is driven by a desire to increase potential for successful and timely re-vegetation and site 

stability. Plant diversity and habitat functionality are directly impacted by the seed choices applied to an 

area slated to be reclaimed or restored. To maintain as much stability and ecological function this section 

makes recommendations to specifically aid a proponent’s selection process. 

• Select site-appropriate, adapted native plant materials based on the ESD, Desired Plant 

Community, and commercially available native species adapted to the species identified in the 

Desired Plant Community /ESD. Seeds may be obtained from commercial sources of certified 

weed-free seed mixes. Alternatively, local collections may be used provided they are collected in 

an area without weedy species. 

• Perennial naturalized species may be used when attempts to reclaim using native plants have not 

succeeded for a minimum of five full growing seasons. Reclamation should succeed using native 

species if soils are properly managed, precipitation is not limiting, seed mixes are carefully 

selected, and seeded areas protected from grazing. 

• Based upon site-specific conditions, a decision may be made to use non-natives sooner than 

identified above and will be used in only unique conditions defined in the site specific 

reclamation plan, and approved by the Authorizing/Line Officer. 

MULCH 

Use of mulch during reclamation may enhance chances for successful vegetation reestablishment. 

Mulches can help control wind and water erosion, retain and collect seed, increase and prolong soil water 

capacity, and add organic compounds to the soil. Mulches are best applied after seeding to ensure proper 

seed contact with soil. Mulch may include hay, small-grain straw, wood fiber, live mulch, cotton, jute, or 
Draft EIS Appendix C 

Wyoming Sage-grouse Land Use Plan Amendment C-19

synthetic netting. Straw mulch should contain fibers long enough to facilitate crimping and provide the 

greatest cover. 

When mulching with cereal grain straw or grass hay, apply in sufficient amounts to provide 70 percent 

ground cover. Mulch rate shall be determined using current erosion prediction technology to reach the soil 

erosion objective (NRCS 2005).

When mulching with wood products such as wood chips, bark, or shavings or other wood materials, apply 

to a 2-inch thickness if the soil is not well-drained and to a 3- to 4-inch thickness if drainage is good. 

More finely textured mulches, which allow less oxygen penetration than coarser materials, should be no 

thicker than one or two inches. The mulch material shall provide no greater than 80 percent ground cover 

in order to ensure adequate air drainage (NRCS 2005). 

Gravel or other inorganic material shall be applied approximately two inches thick and shall consist of 

pieces 0.75 inch to two inches in diameter. The mulch material shall provide no more than 90 percent 

ground cover in order to ensure adequate air drainage (NRCS 2005).

Mulch shall be applied at a rate that achieves 50 percent ground cover to provide protection from erosion 

and runoff and yet allow adequate light and air penetration to the seedbed to ensure proper germination, 

emergence, and disease suppression (NRCS 2005). 

Any mulch used must be certified free from mold, fungi, or noxious or invasive weed seeds. 

LIVE PLANTINGS 

Live plants can be planted on disturbed sites and, with proper site preparation, can greatly enhance 

restoration efforts and shorten time frames. Proponents can buy bare root and container stock directly 

from vendors or can contract seed collection and growth from local growers. Another strategy is to use an 

excavator to collect clumps of plants from the site and plant them either on reserved topsoil piles and/or 

on restoration sites during recontouring. These clumps can provide native seed and soil flora as well as 

collect precipitation and provide shade for newly emerging plants.
