APPENDIX A

VEGETATION SAMPLING METHODS AND RECLAMATION SUCCESS STANDARDS FOR SURFACE COAL MINING OPERATIONS

Introduction

Procedures specified in this document are required for surface coal mining operators per its reference in Chapter 2, Section 2(a)(vi)(C) of the WDEQ/LQD Rules and Regulations. Permission for significant departures from this Appendix should be requested by formal proposal to the Division. Proposed alter- natives will be evaluated by the state and federal authorities prior to approval and implementation.

Alternative methods which are equally acceptable to those recommended in this Appendix will be given due consideration.

This document outlines acceptable procedures for generation, analysis and presentation of vegetation data and revegetation practices to assist a permit applicant with respect to the permit application require- ments of W.S. § 35-11-406(a)(vii), (b)(i) and (b)(iii), Sections 2(a)(vi)(A) & (B), 2(a)(vi)(C), and 2(b)(iv)(C) of Chapter 2 of LQD Rules and Regulations and Sections 2(a)(i), 2(a)(ii), 2(d)(i) through (xiv) of Chapter of LQD Rules and Regulations. The description of lands not previously permitted should be in accordance with methods specified in this document or in accordance with an approved alternative.

Renewal applications may utilize vegetation baseline data collected using earlier approved methods if the results are part of the currently approved mine permit.

The type and amount of vegetation information required for mining permit applications may be modified depending upon:

a. The type of land disturbed and/or the type and acreage of disturbance.

b. The size of the permit area.

This document outlines acceptable procedures for:

A. Designing and executing premining baseline vegetation inventories.

B. Documenting the premining land uses and the capability of the existing plant communities to support those uses.

C. Establishing and evaluating appropriate postmining land uses.

D. Formulating a sound revegetation plan by choosing appropriate plant species and plant community types which will support the postmining land uses.

E. Establishing quantitative and qualitative vegetation parameters which serve as reclamation success standards for purposes of final bond release.

F. Preparing sections of Appendices D-1, D-8, and D-11 and the Reclamation Plan.

G. Evaluating the success of revegetation efforts and for eventual request of full bond release.

These procedures constitute an acceptable premining vegetation inventory. Other methods and types of inventories may be acceptable if they meet or exceed the objectives of this appendix.

Failure to receive prior approval for alternative procedures may cause significant delays during permit review, and rejection of the sampling methods and procedures if these do not result in an equivalent data base. WDEQ/LQD strongly encourages cooperative interactions among the regulatory authority, prospective applicants and consultants to prospective applicants during the design and execution of baseline inventories and preparation of permit applications.

A. Mapping of Plant Communities

The plant communities or vegetation types of the entire permit area shall be delineated on an aerial mosaic photograph or topographic base map. The mapping should be extended to adjacent areas (0.8 km) on all sides of the permit area boundary or study area boundary.

This suggested extension beyond the permit area applies only to mapping of community types. This suggestion does not refer to sampling of areas outside the permit area.

The LQD does not recommend the use of SCS range sites for the mapping of premining plant communities. The range site concept does not facilitate practical units for reclamation pur- poses.

The map scale should be between 1:4,800 and 1:10,000 (approximately 1 inch equal to 400-700

feet).

The vegetation map should clearly and accurately show all appropriate legend information out- lined under the heading “Maps” in WDEQ/LQD Guidelines No. 6 or 6A. In addition, the veg- etation map should identify all sample locations, accurately locate all Control Areas (CONA) (See Glossary), identify and describe the type and extent of all existing disturbances and identify all areas to be affected by mining and associated activities, including access roads, railroad spurs, etc.

B. Sampling of Plant Communities

Each defined plant community of the permit area and all CONAs should be sampled for the following parameters:

1. % vegetation cover by species

2. % total cover (= sum of all species)

3. % total ground cover (= vegetation + litter + rock)

4. % bare ground

5. herbaceous production by species

6. total herbaceous production

7. density and distribution of full shrubs (and subshrubs when appropriate)

8. density of trees

9. species diversity and species composition The LQD prefers that these vegetation parameters be estimated by vegetation type, considering

the entire permit area as a single unit, i.e. without a distinction between affected and non-affected areas. The LQD feels that sampling the entire permit area will:

1. facilitate the derivation of more accurate quantitative and qualitative revegetation success standards;

2. provide the operator greater flexibility in planning the location and progression of pits and the location of mining facilities.

However, the applicant should also consider their chosen method of evaluating revegetation success (Sections III.B. and VIII.B.) when deciding whether to distinguish between affected and non-affected areas for sampling purposes.

Both absolute and relative values for % species cover, % vegetation cover, % total ground cover, herbaceous production by species and total herbaceous production should be provided. The absolute values of % vegetation cover, % total cover and total herbaceous production constitute the quantitative revegetation success goals, as per Chapter 4, Section 2(d)(x), for evaluation of full bond release. The relative values of cover and production are used to evaluate the representa- tive nature of the CONAs and may be used in evaluating postmining species diversity and species composition as per Chapter 4, Section 2(d)(x).

Please see the Glossary for definitional distinctions between absolute and relative values.

C. Establishing and Sampling Control Areas or Reference Areas

The applicant should establish a Control Area (CONA) or Reference Area (REFA) for each vegetation type, in excess of 10 acres, which will be disturbed (or a greater area approved by the Division) unless the Division has agreed that reestablishment of the vegetation type will not be required. For the sake of brevity, this guideline will generally use only the term CONA. How- ever, all applicants should clearly understand that either the CONA or REFA concept is an ac- ceptable procedure for the evaluation of revegetation success under provisions of Chapter 4, Section 2(d)(x).

Sections III.B. and VIII.B. describe the conceptual distinctions between the use of CONAs or REFAs. Applicants may develop, propose and request approval for alternatives to CONAs or REFAS for the evaluation of revegetation success.

Each CONA should be marked on the vegetation map, should be permanently marked in the field, and should be managed in a fashion equivalent to all other non-affected lands within the permit area. By definition the land units chosen as CONAs should remain unaffected by mining and associated activities over the life of the mine, and they cannot be moved without resampling the entire type they represent.

The applicant should present vegetation data on each community type and each CONA in a fash- ion which facilitates evaluation of the representative nature of each CONA. A tabular summary might best achieve this comparison (see Appendix V, Table 3).

D. Describing the Plant Communities

Each plant community and the representative CONA should be verbally described. The descrip- tion should include the general vegetation composition, the dominant plant species, characteristic topography, soil types, average slope, aspect and interspersion with or relationship to other community types. The quantitative and qualitative vegetation information may be best presented in a tabular format (Appendix V, Table 2).

If noxious (designated) or declared weeds (see Appendix I) comprise more than 25% of the vegetation cover on three (3) or more contiguous acres, these areas should be mapped as distinct vegetation types and identified on the vegetation map. These weedy species should be noted in the species list; their presence in any of the mapped community types should also be noted.

Quantitative sampling should not be performed on noxious weed mapping units.

The presence of selenium indicators (Appendix III) should also be noted and their distribution discussed.

The applicant should present the following information in a tabular format (see Appendix V, Table 1):

1. Total acreage of each vegetation type on the permit area.

2. Total acreage of each vegetation type sampled on the study area, if the study area is larger than the permit area.

3. Total acreage of each vegetation type affected by mining and associated activities.

4. % of each vegetation type affected by mining and associated activities.

5. Total acreage of each CONA.

6. Total acreage of all other mapping units, e.g. reservoirs, cropland, pastureland, hayland, existing disturbed areas.

A 3 1/2" x 5" (or larger) photograph or a 2-3 frame panoramic sequence showing the general features of each community type and its representative CONA should be provided in the vegeta- tion report. Photocopies of photographs are not acceptable. The location of all photographs should be noted on the vegetation map.

.E.Compiling a Plant Species List

The applicant should compile a list of the vascular plants of the permit area, including plant species observed but not actually recorded during sampling. The species list should be field checked and updated at least once a month from April through September during the field season when baseline sampling is performed. Regional and seasonal phenological processes should determine the actual compilation time period.

The plant species should be listed by scientific binomial and common name under life-form categories. Suggested categories include annual grasses, perennial grasses, grass-like species, forbs, succulents, full shrubs, subshrubs and trees.

The applicant should list the literature and/or personnel contacted for identification of plant species and note the location of any herbarium samples collected during the baseline inventory. A specimen of the following may be requested to confirm its occurrence:

1.  any plant of special concern (Appendix IV).

2. any species which is similar to a plant of special concern;

3. any species not previously recorded in Wyoming.

4. any species out of its known range.

The applicant should specifically note any plants of special concern (Appendix IV) which occur on or adjacent to the permit area.

F. Sample Adequacy

The applicant should attain formula-based sample adequacy or achieve the maximum sample size for each of the following vegetation parameters in each vegetation type and each CONA:

1. % vegetation cover (absolute value only).

2. % total ground cover (absolute value only).

3. Total herbaceous production (absolute value only).

Section IV of this appendix outlines procedures for calculating sample adequacy and lists maxi- mum and minimum sample sizes.

II. Detailed Qualitative and Quantitative Sampling Procedures

A. Choice of Sample Locations

All sample locations must be chosen by random or systematic procedures. Random procedures are discussed in most standard statistical texts. The selection of sample locations must be done objectively in the lab or office, not in the field. Grid line intervals (when used) should be no more than 65 meters on the ground. After the sample locations are selected, pacing from easily identifiable land marks is sufficiently accurate to locate them in the field.

Systematic sampling is described in Cochran (1977), Chapter 8. Systematic samples are accept- able only if each vegetation type is entirely covered. Calculations for systematic samples may be done by assuming the sample is random.

Sample locations must not be discarded because they are located on areas which are barren or otherwise seem atypical. However, sample locations which fall within recognizable and distinct inclusions within a given vegetation type, on obvious ecotones between types or on areas obvi- ously disturbed by human activities or for land management practices, may be excluded during actual sampling. The applicant should carefully note and report in the permit application, Appen- dix D-8, all such occurrences.

The same procedures should be used for choosing sample locations in CONAs as in the permit area as a whole. These procedures should be clearly described in the permit application, Appen- dix D-8.

B. Choosing Sampling Methods

The quantitative vegetation data requested in this appendix can be gathered using the basic meth- ods of quadrants and/or transects. The choice of methods lies with the applicant. The choice should be based upon:

1. The specific parameter being measured.

2. The degree of statistical accuracy desired.

3. Operator knowledge of the permit area and its plant communities.

4. Operator experience in using a given technique.

The methods discussed in this guideline have been widely used in plant communities of Wyo- ming. In general, they have provided sufficiently detailed and accurate information to meet the permit application requirements of W.S. § 35-11-406 and Chapters 2 and 4 of LQD Rules and Regulations. In particular, the methods discussed in this appendix have consistently provided the type, quantity and quality of data necessary to:

1. document the highest previous use of the land within a permit area.

2. document that the regional plant communities can or cannot support the prevailing land uses.

3. develop sound reclamation and revegetation methods.

4. establish sound quantitative and qualitative revegetation success goals.

Investigators have devised numerous study designs, sampling regimes and sampling methods for, vegetation analysis. Some of these procedures variously known as two-stage sampling, double sampling, cluster sampling, stratified sampling, etc., have been used for baseline vegetation inventories in Wyoming. However, in general these methods have not proven satisfactory for attaining adequate baseline information. Operationally, the large variance terms associated with these sampling methods have caused serious difficulties in attaining the sample adequacy tests of this appendix. The LQD does not recommend use of these procedures.

The references listed in Appendix VI may provide useful information regarding sampling meth- ods.

1. Use of Quadrats

All of the required vegetation parameters can be estimated using quadrants. However, a single quadrant size and shape may not be appropriate for all parameters. Furthermore, there is no absolute, universal method for determining quadrant size or shape. Quadrant size and shape should be selected to reduce variance and thereby reduce the number of samples needed. The quadrant should be sufficiently large so that:

a. Separation, counting and measurement of the individual plants can be performed with relative ease.

b. Sampling efficiency is as high as possible.

c.  The largest plant within the quadrant does not fill the quadrant.

d.  All quadrants enclose some vegetation.

2. Use of Line Transects

All transects should be at least 50 meters in length. If a transect runs out of a given vegeta- tion community, select a new random orientation, at the point where the transect leaves the vegetation type, which will return the transect to the same vegetation type.

If quadrants are spaced along a transect, no fewer than five (5) quadrants should be placed along each transect. If point-intercept methods are employed along a 50-meter transect, no fewer than fifty (50) sample points should be evenly spaced along each transect.

Independent of the method, each transect comprises a sample size (N) of one (1).

C. Suggested Sampling Procedures for Specific Vegetation Parameters

1. Cover Parameters

Chapter 1 of LQD Rules and Regulations defines “cover,” as vegetation, litter and rock over the soil which intercept rainfall. This definition describes % total ground cover. Operation- ally, vegetation cover is the vertical projection of the general outline of plants (ignoring minor gaps between branches and holes in the canopy) to the ground surface expressed as a percent of a surface reference unit.

The applicant should collect data for the following categories:

1.  % vegetation cover by species

2.  % total vegetation cover (=sum of all species)

3.  % total ground cover (=vegetation + litter + rock)

4.  % bare ground

The original absolute cover values for individual species should be manipulated to provide relative cover values.

For sampling purposes rock may be considered any stone or mineral matter at least one (1) square centimeter in size. Litter is any plant part, lying on the ground surface, whose struc- tural integrity remains recognizable.

a.  Quadrat Methods

Species cover, vegetation cover and total ground cover can be determined from appropri- ately sized quadrants by ocular estimation. The considerations for determining quadrat size and shape discussed earlier clearly apply to cover sampling.

b.  Line Transect Methods

Species cover, vegetation cover and total cover can be determined from procedures based on line transects. The point intercept method has been frequently and successfully applied in Wyoming plant communities. Point samples may be determined using the following tools: sharpened rod or pin or an ocular siting device projected vertically downward to the sample location on the transect.

When estimating % cover by species, only the first hit on each species should be re- corded and used in the calculations. If one projection intercepts the same species more than once, record only the “first hit” on that species. If one projection intercepts more than one species, separate hits should be recorded for each on each species.

When estimating % total vegetation cover, the first “hit” per projection should be used.

In general, the line transect should be at least fifty (50) meters long; Point samples should be collected at one (1) meter intervals. Each transect constitutes a sample size

1. (N) of one (1).

   2. Total Herbaceous Production

   In this appendix, the term production will describe an estimate of the total herbaceous stand- ing crop biomass which is measured at or near the expected peak of the standing crop. Her- baceous production by species and total herbaceous production should be estimated for each community type and its representative CONA.

   a.  Grazing Exclosures

   All production estimates should be taken from within grazing exclosures. Random sample points (exclosure locations) should be established before the growing season.

   The exclosures should be placed in the field on or before April 15th or as soon after snowmelt as field conditions permit. Cages should be placed at this time to avoid pos- sible data complications from snow accumulation through the winter.

   The number of cages needed can be estimated from preliminary sampling, from results of previous vegetation sampling on-site or from other vegetation surveys in similar vegeta- tion types in the area. All permit applications and approved permits for mining in Wyo- ming are public documents and open to review. Analysis of existing data from appli- cable documents should be an integral part of all study designs for a baseline vegetation inventory. Applicants should establish several extra exclosures in each vegetation type and CONA to accommodate possible loss of some exclosures due to destruction by cattle, inaccessible locations, placement in an inclusion, etc.

   The cage size and quadrant size must be chosen with each other in mind. The exclosure must be sufficiently large to accommodate the sample quadrant and to provide a buffer area which reduces the potential for serious edge effects.

   All exclosures should be removed when the inventory is complete.

   b.  Field Methods

   The standing crop biomass of all herbaceous species should be harvested in each quad- rant. Full shrubs, succulents, annual grasses, annual forbs, Yucca spp., noxious weeds, cushion plants and trees should not be harvested. The seasonal growth of subshrubs should be harvested (see Appendix II) when accurate density data are unattainable. If annual grasses and/or annual forbs are major community components, these life forms should be clipped.

   The vegetation should be clipped by species in each vegetation type and each CONA.

   The minor or remaining species can be harvested by life form category (Section I. E.).

   All biomass should be carefully dried in an oven to a constant weight and recorded to the nearest 0.1 gram. Data should be reported in grams per square meter.

   c.  Data on Cropland, Hayland or Pastureland

   Land units which have experienced special management such as cropland or pastureland

   (see definitions under “cropland and pastureland”, respectively) should be delineated and identified on the vegetation map. Best available information on the current and historical management of these lands and their production must be provided. The applicant should consult appropriate land owners or managers for these data. All sources for this infor- mation should be identified in the text. Harvest data should be presented in units of grams per square meter, if possible. Cropland need not be sampled for any of the veg-

   etation parameters outlined in Section I. B. However, some vegetation sampling of pasturelands and haylands may be appropriate. It is strongly recommended that the applicant contact LQD during the initial planning stages of the proposed vegetation inventories to discuss appropriate sampling procedures relative to these land units.

   In general, CONAs or REFAs need not be established for these land units. The premining production data, similar undisturbed management units or average area agri- cultural statistics information may serve as reclamation success standards per Chapter 4, Section 2(d)(x)(I). However, given site specific conditions it may be appropriate to establish CONAs or REFAs for haylands and pasturelands. The need to establish CONAs or REFAs should be discussed with the LQD during the initial planning stages of the vegetation inventory.

   3. Shrub Habitat Characteristics

   The postmining density, composition and distribution of shrubs shall be based upon site- specific evaluation of the premining vegetation and wildlife use. Except where a lesser den- sity is justified from premining conditions, at least 20 percent of the eligible land shall be restored to shrub patches supporting an average density of one shrub per square meter (Chap- ter 4, Section 2(d)(x)(E)). Thus, the baseline vegetation inventory shall include premining shrub distribution data, to include an estimation of the distribution and areal extent of shrub clumps or patches. Shrub density and cover data shall be components of the shrub distribu- tion information.

   When shrub density data are estimated, they shall be gathered from each community, but not from CONAs, REFAS OR MINIMUM EXREFAS. Shrubs shall be divided into woody species (full shrubs) and suffrutescent species (subshrubs) for sampling purposes (see Appen- dix II).

   Shrub density counts shall be performed within a 50 square meter area using a plot shape appropriate to the community.

   Data shall be recorded by species and then manipulated to formulate full shrub and subshrub density values for each community type. The data shall be reported as number per square meter and number per acre. The growth characteristics of certain subshrub species under various environmental conditions may prohibit accurate density counts. Under these circum- stances, consultation with LQD may provide for the collection of seasonal growth biomass as substitute method of characterizing these plant species.

   All shrub density data collected after August 6, 1996 shall be subject to sample adequacy

   tests specified in Section IV. of this Appendix. However, all shrub density data collected prior to August 6, 1996 shall not be subject to sample adequacy tests unless that shrub density data is being used to fulfill the 20% standard. In general, when sampling is conducted which is not subject to sample adequacy, the number of shrub density sample points should corre- spond to the number of cover samples in each community type.

   4. Tree Distribution

   Chapter 4, Section 2(d)(x)(E) requires that trees be returned to a density equal to the pre-mining conditions on all surface mining operations.

   Plotless distance, methods and direct counts have been used to estimate tree densities in Wyoming plant communities. Because of the patterns of distribution and general paucity of tree species on lands affected by mining in Wyoming, direct count methods may be the most accurate and efficient. Depending upon community characteristics, plant distribution, plant size and availability of source materials, direct counts may be made by field reconnaissance or from aerial photographs. If plotless methods are used, 15-20 randomly chosen sample points should be sampled. Some estimate of height and/or age distribution should also be provided.

   Tree density data are not required for CONAs. Tree density data are not subject to sample adequacy tests.

   The general locations or concentrations of trees should be illustrated on the vegetation map.

   5. Species Composition and Species Diversity

   Chapter 1 of LQD Rules and Regulations defines species composition as the “...number, kinds, amount and quality of species” and species diversity as the “...number of species per unit area”. Chapter 4, Section 2(d)(x) establishes suitable postmining species diversity and composition as revegetation success goals for all operators.

   The concept of species diversity is complex. Some researchers suggest that species diversity can be measured by indices of diversity. Though numerous indices of diversity have been developed, no standard index exists and no single index is necessarily better than another.

   The applicant should collect premining data which can be manipulated to document the species composition and species diversity of premining plant communities.

   D. Recording of Sample Methodology

   All sampling procedures must be presented clearly in the text of Appendix D-8. The applicant should use the same procedures for sampling vegetation types and CONAS.

   III. Establishing Revegetation Success Goals

   A. Quantitative and Qualitative Vegetation Standards

   Chapter 4, Section 2(a)(i) requires that reclamation restore the land to a condition equal to or greater than the “highest previous use”. Chapter 4, Section 2(d)(x) outlines specific vegetation parameters which constitute revegetation success goals when reclaimed lands are considered for full bond release.

   These qualitative and quantitative vegetation parameters which constitute revegetation success goals include:

   1. % vegetation cover (absolute value).

   2. % total ground cover (absolute value).

   3. Total production for herbaceous species (absolute value).

   4. Density of full shrub and subshrub species (postmining shrub habitat).

   5. Areal extent of dense shrub mosaics.

   6. Density of trees.

   7. Species diversity and species composition.

   8. Ability to withstand grazing pressure.

   9. Attainment of these parameters for the last (2) consecutive years of the bonding period.

   The premining values of these parameters, estimated from the vegetation types actually affected by mining and/or from other undisturbed portions of the same type which are representative of the affected vegetation types, are used to generate the postmining revegetation success goals.

   The baseline vegetation inventory should generate a single quantitative or qualitative value for parameters 1, 2, 3, 5 and 6 from each vegetation type and its representative CONA. Each quanti- tative and qualitative goal should be clearly presented in the permit application, Appendix D-8, and at least referenced in the Reclamation Plan.

   B. Establishing Land Units for Use in Evaluating Revegetation Success for Full Bond Release

   As noted above, Chapter 4 specifies the vegetation parameters which constitute revegetation success goals for full bond release and requires the LQD Administrator to specify methods for evaluating attainment of these goals. At this time, all approved success evaluation methods must

   be based upon analysis of an undisturbed land unit, i.e. a control area or reference area. As discussed more fully in Section VIII, several methods of evaluating revegetation success exist.

   Each of the methods conceptually share several common features:

   1. During the baseline inventory, the applicant delineates portions of vegetation types which will remain undisturbed and which are biotically and abiotically representative of vegeta- tion types affected by mining activities.

   2. During the baseline inventory, standard sampling methods are used to estimate the premining values of the vegetation parameters (outlined above in Section III.A.) on each affected vegetation type and an undisturbed portion of the same vegetation type. These premining data are used to document the representative nature of the undisturbed unit.

   3. At least two (2) years prior to the desire for full bond release, the revegetation success parameters are again estimated on the revegetated areas and the undisturbed units.

   The applicant should choose which conceptual framework is appropriate for the evaluation of revegetation success under the conditions expected to exist on the mine site. Alternate success standards for evaluating reclamation success may be submitted for approval by the Administrator.

   The applicant must establish at least one land unit, within an undisturbed portion of a vegetation type, which is representative of each vegetation type that will experience ten (10) acres or more of disturbance (or a greater area if approved by the Division).

   The following types of undisturbed land units may be established for use in evaluating revegeta- tion success. The land units themselves and the conceptual framework within which they are used are not interchangeable. The applicant should consistently establish one type of land unit from the following:

   Control Area means a land unit which is representative, in terms of physiography, soils, vegeta- tion and land use history, of a plant community affected by mining activities. The representative nature of the Control Area is verified by subjective (nonstatistical) comparison of its qualitative and quantitative characteristics to similar information from the plant community it typifies.

   Quantitative premining and postmining vegetation data from the Control Area are used to math- ematically adjust premining affected area data for climatic change. These adjusted data are directly compared by statistical procedures (confidence level of 80%, “ = 0.2) to data from a reclaimed vegetation type when evaluating revegetation success for full bond release. Qualitative data are compared by standard procedures agreed to by the applicant or permittee and LQD.

   Reference Area means a land unit which is representative, in terms of physiography, soils, veg- etation and land use history, of a plant community affected by mining activities. The representa- tive nature of the Reference Area is verified by statistical comparison (confidence level of 90%, “ 0. 1) of its absolute values of % vegetation cover, % total ground cover and total herbaceous production to similar data from the plant community it typifies. Species composition and species diversity are subjectively (nonstatistically) evaluated.

   Quantitative postmining vegetation data from the Reference Area are directly compared, by standard statistical procedures (confidence level of 80%, “ = 0.2), to data from a reclaimed vegetation type when evaluating revegetation success for full bond release. Qualitative data are compared by standard procedures agreed to by the applicant or permittee and LQD.

   Note: The following is a special kind of reference area that can be utilized by the operator.

   Extended Reference Area means all the undisturbed portions of a vegetation type which has experienced disturbance by mining activities. The representative nature of the Extended Refer- ence Area is verified by evaluation of vegetation mapping procedures, the adequacy of premining vegetation data, soils data, physiography and land use history information.

   Postmining quantitative vegetation data from the Extended Reference Area are directly compared by standard statistical procedures (confidence level of 80%, “ = 0.2), to data from a reclaimed vegetation type when evaluating revegetation success for full bond release. No mathematical adjustment for climatic change is made. Qualitative data are compared by standard procedures agreed to by the applicant or permittee and LQD.

   A Control Area (CONA) or Reference Area (REFA) should be at least two (2) acres in size.

   Larger land units are preferred, whenever possible, for the following reasons: 1) to reduce the variability (in terms of the abiotic and biotic characteristics) between the CONAs or REFAs and the communities they typify; and 2) to reduce the potential adverse impacts to the CONAs or REFAs due to intensive sampling at the time of bond release, which becomes more critical when successive units of reclaimed lands are being evaluated for revegetation success.

   All CONAs or REFAs should remain undisturbed by mining activities and should be managed in a fashion which will not cause significant, management-related changes in the vegetation param- eters used to evaluate revegetation success. Permittees should contact LQD if they perceive the need to relocate a previously established CONA or REFA.

   Section VIII.B. further outlines operational differences among the CONA and REFA concepts when evaluating the success of revegetation.

   For existing mining operations where vegetation data were not collected prior to disturbance, another type of land unit may be established for purposes of evaluating revegetation success.

   Comparison Area means a land unit which is representative, in terms of physiography, soils, vegetation and land use history, of a premining plant community from which no vegetation data were collected prior to disturbance. The representative nature of the Comparison Area may be validated by a subjective field reconnaissance of the site or by subjective evaluation of vegetation data generated by a sampling program. The establishment procedures should be agreed to by the permittee or applicant and the LQD prior to establishment.

   Postmining quantitative data from the comparison area are directly compared, by standard statisti- cal procedure (confidence level of 80%, “ = 0.2), to data from a reclaimed vegetation type when evaluating revegetation success for full bond release. No mathematical adjustment for climatic change is made. Qualitative data are compared by standard procedure agreed to by the permittee or applicant and LQD.

   A Comparison Area should be at least two (2) acres in size and should be managed in a fashion which will not cause significant changes in the vegetation parameters used to evaluate revegeta- tion success. The permittee or applicant should establish and request approval of the Comparison Area at least two (2) years prior to an anticipated request for full bond release.

   IV. Estimating Adequate Sample Size A. General Considerations

   The applicant must achieve sample adequacy or execute the maximum sample size for each CONA and for each vegetation type.

   The applicant must achieve sample adequacy for each of the following parameters independently in each CONA and each vegetation type.

   1. % vegetation cover (absolute cover).

   2. % total ground cover (absolute cover).

   3. Total herbaceous production.

   B. Procedures

   The applicant should sample at least the minimum number of sample locations as outlined by

   Table 2. below. The following formula should then be used in an incremental and iterative fashion to estimate sample adequacy: nmin~=~{2{(sz)}^2} over {(d{overline x})^2} where:

   nmin = the number of sample points needed in a given vegetation type

   sample standard deviation = S = sqrt {{(3x_i^2-[{(3x_i)} SUP 2/n])} over {n-1}}

   z = the z statistic d = acceptable amount of inherent variability to be identified between the sample mean and the true population mean; See Table 1 below for d and z values.

   {overline x} = sample mean for cover or production

   If sample adequacy is not met in an incremental fashion, the sample adequacy test should be applied until the maximum number of samples, as outlined by Table 2, is reached. Alternatively, the appli- cant may simply establish and sample the maximum number of samples presented in Table 2.

   The applicant should always present analyses of sample adequacy using the nmin formula. These analyses are best presented in a tabular format (see Appendix V, Table 4). In order that LQD per- sonnel may check these data, all parameters of the formula must be clearly presented.

   If the calculated nmin exceeds the maximum sample size of Table 2, the applicant should indicate the confidence level (d value) achieved by solving for z (assuming n actual = nmin). The applicant should also present a brief explanation of why the sample was unusually variable and thus formula adequacy was not achieved.

   C. Determining d and z values

   The community composition determines the d and z values for assessment of sample adequacy for total herbaceous production. Two arbitrary community types are defined as follows:

   1. A grassland community is a vegetation type where the contribution of the cover of full shrubs and subshrubs comprises less than 20% of the total cover of all species.

   2. A shrubland community is a vegetation type where the contribution of the cover of full shrubs and subshrubs comprises more than 20% of the total cover of all species.

   These definitions are based upon analyses of existing premining vegetation data. Their derivation is available from LQD upon request.

   After making this operational distinction based upon sampling data, choose the appropriate pa- rameters from Table 1 below. The parameters used for evaluation of % vegetation cover and % total ground cover do not vary with community type. Consult Table 1 for appropriate param- eters.

   Table 1.  z and d values for use in the sample adequacy formula Vegetation parameter z d % vegetation cover, grassland & shrubland 1.28 0.1

   % total ground cover, grassland & shrubland 1.28 0.1

   total herbaceous production, grassland 1.28 0.1

   total herbaceous production, shrubland 0.84 0.2

   50 m2 shrub density plots 0.84 0.2

   D.Determining Minimum and Maximum Sample Sizes

   Table 2. Minimum and maximum sample sizes for various sampling methods

   Sampling Method sample size minimum maximum

   1. In Control or Reference Areas quadrats 10 30

   transects with quadrats 5 30

   intercept transects 15 30

   2.  In Vegetation Types quadrats 15 50

   transects with quadrats 7 30

   intercept transects 20 50

   50 m2 shrub density plots 15 *

   * if sample adequacy can not be achieved after sampling 50 shrub density plots, the operator shall contact the LQD for guidance The maximum and minimum sample sizes for CONAs also apply to vegetation types which cover fewer than 30 ha (80 acres) or vegetation types which will experience fewer than 4 ha (10 acres) of disturbance. The applicant should consult LQD for direction in such situations.

   The maximum and minimum sample sizes were constructed with the following qualifications:

   1. cover, production and density are being estimated using appropriately sized quadrats.

   2. line transects are 50m long with 50 evenly-spaced estimation points.

   3. all sample points are randomly or systematically chosen.

   4. vegetation types are accurately and professionally delineated, mapped and sampled.

   5. a permit area no larger than 10,000 acres. If a permit area exceeds 10,000 acres it may require a larger sample size. The applicant should consult LQD for direction in such situations.

   6. shrub density is estimated using a 50 square meter plot

   Compromise of any of these criteria may result in serious difficulties with sample adequacy requirements and may compromise acceptability of the baseline vegetation inventory.

   V. Suggested Timetable for Components of the Vegetation Inventory Design vegetation study Any time - discuss with DEQ/LQD well in advance of field sampling season Map vegetation types of entire Any time - field check during growing permit area season, prior to baseline sampling.

   Describe each vegetation type Any time - confirm dominant species during and after field sampling.

   E. Literature Cited

   F. Raw Data VII. Developing a Revegetation Plan

   A. General Considerations

   A postmining revegetation plan should incorporate information from the premining baseline vegeta- tion inventory, to include:

   1. Input and concurrence from the “resident or agricultural landowner” regarding the applicant’s proposed reclamation plan (as per W.S. § 35-11-406(b)(xi)).

   2. The premining land uses and the plant species which supported those land uses.

   3. The type, number, size and distribution of premining plant communities, croplands or pasturelands.

   4. The major plant species from each premining plant community, cropland or pastureland.

   5. The growth form (bunch or sod-forming) and seasonal variety (cool or warm season) of the dominant grass species.

   6. Type and distribution of full shrubs, subshrubs and trees. General proposed locations of shrub mosaics including the areas which are expected to be most conducive to shrub estab- lishment should be shown on a map of the postmining landscape.

   The applicant should consider returning the major vegetation types, major plant species and growth forms in numbers and configurations which will support the postmining land uses

   (see definitions) .

   B. Seed Mixtures After choosing the postmining land uses and considering the dominant postmining topographic fea- tures and landowner desires, the applicant should develop different seed mixes which will accommo- date the postmining land uses and differences in soils, moisture conditions, exposures etc. on the postmining landscape. Also, considering seed availability, growth form, seasonal variety and pre- vailing dominant species, each proposed seed mixture should:

   1. contain no fewer than four (4) herbaceous species, unless a proposed land use (e.g. man- aged hayland or pastureland) requires fewer species;

   2. contain the native dominant herbaceous species which support the postmining land uses;

   3. if needed, contain additional species native to the region which support the postmining land uses;

   4. contain naturalized, introduced species only if additional herbaceous species are needed, or if suitable, native species are a unavailable or if naturalized species are superior for a specialized land use (e.g. managed hayland or pastureland);

   5. contain full shrub and/or subshrub species when these species will support the postmining land uses. To increase postmining species diversity and establish shrub mosaics, shrub mixtures should be developed and seeded separately from the herbaceous mixtures (see Coenenberg, 1982);

   6. contain native forb species if natural reinvasion of forbs will be limited by site-specific conditions.

   For coal operators, seed mixtures for all postmining communities which will be jointly used by livestock and wildlife should include full shrub and/or subshrub species.

   The proposed postmining location of each seed mixture should be illustrated on a postmining con- tour map.

   Seed mixtures for temporary stabilization of sites, stockpiles or other special uses should also be developed considering site-specific characteristics. The LQD strongly discourages the use of ag- gressive introduced plant species, particularly crested wheatgrass, on topsoil stockpiles. The con- cern lies in the possible carry over of such species to postmine lands during the replacement of stockpiled topsoil, which could ultimately result in problems (on the applicant’s part) in meeting species diversity requirements at the time of bond release due to the predominance of the above mentioned introduced species. The LQD feels that other vigorous, rhizomatous species are readily available for such uses.

   C. Seeding Practices

   In general, all seed mixtures should total at least 14 lbs. PLS (Pure Live Seed) per acre when drill seeded. Seeding depth should be 1/4 to 1/2 inch when drilled. However, small seeded species (e.g.

   big sagebrush, blue grama, etc.) establish best when the seed is broadcast and lightly covered. Drill seeding should occur on the contour or across the prevailing wind direction. If seed mixtures are broadcast, the rate of application should be doubled and the seed should be lightly covered.

   The LQD strongly recommends that the applicant consider staggered seeding methods to facilitate the establishment of warm season grasses and shrubs and/or to revegetate areas with poor quality substrates, (e.g. see Coenenberg, 1982; DePuit, 1982). Similarly, direct backhaul of live topsoil has proven very beneficial to establishment of diverse postmining plant communities (DePuit, 1984).

   In general, the most appropriate seeding times are after October 15th or before April 15th. The soil should not be frozen or snowcovered. An extension to May 15th entails minimal risk of failure in most years. The actual choice of seeding time should be based on regional climatic conditions, site- specific environmental conditions, operator preference and operator experience.

   Chapter 2, Section 2(b)(iv)(C) and Chapter 4, Section 2(d)(iv) require the use of mulch on all reclaimed lands, unless specific permission is granted for not using mulch. The LQD considers a seeded cover crop/stubble mulches as an acceptable alternative to crimped (hay or straw) mulch. In fact, research (Schuman, et. al. 1980) has shown that cover crop/stubble mulch have several advan- tages over the use of crimped hay or straw mulch including:

   1. decreased operation and application costs.

   2. better wind and water erosion control.

   3. increased water infiltration.

   4. increased weed control.

   5. less temperature fluctuation at shallow soil depths.

   In the event that a crimped mulch is utilized, weed free native hay is preferred over the use of domestic hay or straw mulch. This reduces the chances of introducing noxious weeds onto the reclaimed area and can promote the introduction of desirable native species.

   In general, the LQD does not recommend hydromulching as a permanent revegetation practice.

   Hydromulching has proven useful only for temporary reclamation activities.

   D. Husbandry Practices

   The applicant should clearly discuss the postmining husbandry practices it expects to use on reveg- etated communities. The bonding period usually begins after the permittee has completed fertiliz- ing, seeding, irrigation or other work to ensure revegetation, Chapter 4, Section 2(d)(x); W.S. § 35- 11-423(a).

   Chapter 4, Section 2(d)(xiii) requires that newly seeded areas must be protected from livestock grazing for a minimum of two (2) years or until the plant community is capable of renewing itself under proper management practices. The newly seeded areas may be protected by fencing or other management practices which meet the intent of this statutory provision.

   E. Postmining Grazing Practices

   Chapter 4, Section 2(d)(xiii) states that the LQD, the permittee and the landowner or land managing agency will mutually determine when domestic livestock grazing will be introduced on revegetated areas. Secondly, as per Chapter 4, Section 2(d)(x) the capability of revegetated areas to withstand livestock grazing pressure is a distinct criterion for full bond release.

   The Reclamation Plan should include some discussion of both the above points. Due to the temporal lag between permit preparation and permanent reclamation activities, the LQD believes that a full, detailed postmining grazing program is not necessary at the permitting stage. However, the appli- cant should, at a minimum, commit to providing a grazing plan prior to the introduction of grazing on reclaimed lands.

   F. Restoration of Shrubs, Subshrubs and Trees

   On coal-mined lands, the postmining density, composition, and distribution of shrubs shall be based upon site-specific evaluation of the premining vegetation and wildlife use. Efforts to achieve the density standard shall be conducted through the application of best technology currently available.

   Except where a lesser density is justified from premining conditions, at least 20 percent of the eligible land shall be restored to shrub patches supporting an average density of one shrub per square meter (Chapter 4, Section 2(d)(x)(E)).

   For coal operators, tree species shall be returned to a postmining density equal to the premining density. The application should detail the age or size of transplants, the nature of the stock (bareroot, tubelings, etc.), the transplanting procedures and methods of protecting the transplanted stock from large and small herbivores.

   G. Literature

   Literature in Appendix VI may provide additional information for construction of revegetation plans.

   Specific acceptable revegetation practices may be found in permits approved by DEQ/LQD; addi- tional proposed practices occur in pending permit applications. Both these sources are public docu- ments. Applicants are encouraged to consult these sources and/or DEQ/LQD for further informa- tion.

   VIII. Testing Adequacy of Reclamation

   The Reclamation Plan should contain a discussion of the applicant’s proposed methods for evalua- tion of revegetation success. The discussion should address all qualitative and quantitative success standards.

   A. Reclamation Success Standards

   Chapter 2, Section 2(b)(xiv) of LQD Rules and Regulations requires that the applicant clearly define the postmining land use(s). Livestock grazing and wildlife habitat are the most commonly proposed postmining land uses. Chapter 4, Section 2(d)(x) defines the following success goals for all opera- tors:

   1. postmining cover equal to premining cover;

   2. postmining production equal to premining production;

   3. species composition and species diversity capable of supporting the postmining land uses;

   4. ability of the reclaimed community to sustain grazing pressure at least equal to premining grazing pressure;

   5. attainment of all of the above for two (2) consecutive years immediately prior to full bond release.

   B. Land Units Used for Evaluating Revegetation Success

   The vegetation parameters which are compared between the Control Area (CONA) or Reference Area (REFA) or Extended Reference Area (EXREFA) and the reclaimed area (RECA) are identical.

   However, the methods used to compare the vegetation parameters differ intrinsically among the methods. These intrinsic differences are explained in Sections 1, 2 and 3 below.

   1. Procedures Using a Control Area

   The CONA concept involves the use of a mathematical adjustment for climatic changes which may have occurred between the dates that the premining and postmining data were collected.

   The CONA concept is used to test the attainment of the success goals of % vegetation cover, % total ground cover and total herbaceous production. The operator should use the same methods in premining and postmining sampling to generate the following parameters:

   Premining

   Affected Area Control Area

   {overline x}_1= percent cover or {overline y}_1= percent cover or production production

   S {overline x}_1^2= variance of mean S {overline y}_1^2 = variance of mean

   Postmining Reclaimed Area Control Area

   {overline x}_2= percent cover or production {overline y}_2= percent cover or production S {overline x}_2^2= variance of mean S {overline y}_2^2= variance of mean

   Where: S {overline x}_2^2 & S {overline y}_2^2 = variance of mean = {3x SUB i SUP 2~-~[{(3x_i)}^2/n]} over {n(n-1)} = {(S)}^2 over n

   If the value of {overline y}_1

   is statistically equal (confidence level = 90%, “ = 0.1) to {overline y}_2, ~{overline x}_1 should be directly compared (confidence level = 80%, “ = 0.2) to {overline x}_2.

   If {overline y}_1 is not statistically equal to {overline y}_2 , an additional parameter, stack{v# overline {x}}, is generated in the following fashion:

   stack{v# overline {x}} = the cover or production goal adjusted for climatic change

   stack{v# overline{x}} =~ ({overline y}_2/{overline y}_1)~C~{overline x}_1

   Reclamation will be considered adequate for % total ground cover, % vegetation cover and total production when the following inequality has been satisfied for two (2) consecutive growing seasons: {overline x} SUB 2~ -~ stack {Ê# {overline x}}~ +~ z_{0.8}~ sqrt{ ~{S{{overline x} _2^2}}~ +~{S{{stack {Ê# overline x}}^2}}}~~{underline >}~~0

   where S{stack {Ê# overline x}}^2 = the estimated variance of {overline x} calculated by left({{overline x} _1^2 over {overline y}_1^2}~ C~S{{overline y}_2^2}right)~ + ~left({overline y}_2^2~C~Sr^2 right)~ + ~left(S{overline y}_2^2~C~Sr^2 right)

   where: Sr^2~{UNDERLINE -}~left({overline x}_1^2 over {overline y}_1^2right)~ left({S{overline x}_1^2} over {{overline x} _1^2}~+~{S{overline y}_1^2} over {{overline y}_1^2}right)

   If {overline x}_2~>~{stack {Ê# overline x}}, the above inequality is met and the lengthy variance calcu- lations are unnecessary.

   An example calculation is available upon request for the entire bond release comparison out- lined above.

   2. Procedures Using a Reference Area

   The REFA concept does not incorporate the use of a mathematical adjustment for climatic change. if climatic change has influenced the vegetation, it is assumed that the individual species and species assemblages of the REFA and RECA will have responded similarly.

   The REFA concept is used to test the attainment of the success goals of % vegetation cover, % total ground cover and total herbaceous production. The operator should use the same methods to sample the REFA and RECA for the last two (2) consecutive years after the minimum bonding period and after the operator considers revegetation successful.

   For each year’s data set, the data from the REFA are directly compared, by standard statisti- cal procedure (confidence level = 80%, “ = 0.2), to the RECA data. The goals of equal cover and production must be achieved for each quantitative parameter for the last two (2) consecutive years of the bonding period.

   3. Procedures Using an Extended Reference Area

   The EXREFA concept is identical to the REFA concept in its statistical comparisons. The intrinsic difference between the EXREFA and REFA concept lies in the postmining sampling of all of the undisturbed area of a given vegetation type, versus the sampling of a small, representative unit, the REFA.

   C. Evaluation of Species Diversity and Species Composition

   The postmining plant communities must have sufficiently diverse species composition (numbers and types of individual species and life forms) and sufficient species diversity (a measure of the variability of the species composition) to support the postmining land uses.

   Appendix D-8 should contain a discussion of premining species composition and species diver- sity. The discussion should include the value (e.g. browse, shelter, grazing, soil protection ) of the major species and communities as a whole. A major species is defined as having relative cover equaling or exceeding two (2) percent. This discussion should be documented by applicable literature.

   The Reclamation Plan should include a discussion of projected postmining species composition and species diversity, and the ability of the species to support the postmining land uses. The composition of reclamation seed mixes and/or special plantings, known species characteristics and life form distribution should form the basis of this discussion.

   The applicant should also include in the Reclamation Plan a conceptual outline of how it proposes to evaluate species diversity and composition when bond release is requested. This outline may include:

   1. a discussion of the species of the reclaimed community and their ability to support and maintain the postmining land uses;

   2. the role of these species in secondary succession;

   3. a direct qualitative comparison of the species composition of the premining and postmining communities;

   4. a direct qualitative comparison of the life forms of the premining and postmining commu- nities using an appropriate index of similarity or other assessment method agreeable to the LQD.

   An index of similarity (Mueller-Dombois and Ellenberg, 1974) may be used to compare the premining and postmining communities. However, such indices should not constitute the sole criterion for evaluation of species diversity.

   DEQ/LQD has developed a suggested format and procedures for evaluation of species composi- tion and species diversity. These documents are available upon request; alternative methods may be appropriate.

   D. Evaluation of Restored Cropland or Pastureland

   Unless specifically approved in a Reclamation Plan, the areal extent of specially managed land units, such as croplands, haylands or pasturelands, should not significantly exceed their areal extent on the premining landscape. If a coal operator desires significant changes in postmining

   land uses, e. g. a significant increase in croplands, the proposal must be justified and approved as per Chapter 2, Section 2(b)(xiv).

   As per Chapter 4, Section 2(d)(x)(I), postmining restoration of cropland is deemed complete when their “productive capability” is equivalent, for at least two (2) consecutive crop years, to premining conditions. Premining cropland production data should be considered in judging restored croplands, whenever said data are available. The equivalency can be assessed by direct comparison of postmining production data to accurate premining production data. Alternatively, the permittee may identify a premining cropland unit whose production capacity will be used as a success standard. Clearly the premining cropland unit must remain unaffected by mining activi- ties, should be managed in an appropriate manner and should accurately represent the disturbed premining croplands. Alternative methods of evaluating cropland may be approved by the Ad- ministrator.

   The LQD Rules and Regulations do not specifically address procedures for evaluating revegeta- tion success on post-mining pasturelands and haylands. The procedures agreed to by the applicant and LQD should be clearly presented in the Reclamation Plan.

   E. Evaluation of Shrub Density

   Introduction

   All land affected after August 6, 1996, excluding cropland, pastureland or treated grazingland as defined in Chapter 1 shall be considered eligible land subject to the standard. Except where a lesser density is justified by premining conditions, at least 20 percent of the eligible land shall be restored to shrub patches supporting an average density of one shrub per square meter (Chapter 4, Section 2(d)(x)(E)).

   The postmining areal extent of shrub patches and specific shrub density(ies) shall be based on the original premining shrub densities in each vegetation community and the percentage each commu- nity contributes to the total eligible land existing in the original permit area and any lands added to the permit area through the amendment process.

   Premine community(ies) identified and sampled during the baseline studies shall serve as the target for bond release unless otherwise approved by the Administrator.

   For bond release purposes, the average postmine total density and species specific density(ies) shall be at least 90 percent of the calculated criteria for the applicable standard.

   CALCULATING THE REQUIRED POSTMINE DENSITY AND SPECIES COMPOSITION

   In order to calculate density and composition, the following must be identified:

   1. Areal extent and premining total density of eligible land by vegetation community;

   2. Relative density for each species;

   3. Dominant premine species which then becomes the target postmine species;

   4. Density of target postmine species using the formula D[1/(N + 1)]; *

   5. Allowable density of postmining residual species; and

   6. Acceptable residual species.

   * D is the postmining total shrub density. When D is less than 1.00, the density of the target postmining species is reduced proportionately. N is the number of primary premining shrub or subshrub species.

   Table 3: Identification of available options

   Option Identification PREMINE

   I Reduced permit-wide full shrub standard < 20% @ > 1/M2

   II Permit-wide full shrub standard > 20% @ > 1/M2

   III Community-specific full shrub standard No restrictions

   IV Community-specific full and subshrub standard No restrictions - add sub-

   shrubs

   The operator shall select one option only for bond release purposes within each permit or amendment area.

   Option I: Permit-wide full shrub density standard; reduction in areal extent; composition based on premining full shrub density only (see Figure 1 for an illustration of this Option). For bond release purposes, no more than two separate acreage/density standards shall be used.

   1.  Reductions in areal extent and shrub density shall be appropriate when the premining vegeta- tion community(ies) supporting at least one shrub per square meter comprised less than 20

   percent of the eligible land. The percentage this community contributed to the total eligible land would then become the percentage of the postmining landscape that is required to sup- port one shrub per square meter. The remainder of the postmining 20 percent areal extent of shrub patches shall be required to support shrubs at a density equalling the next highest density existing in a premining community.

   2.  Compute the relative premining dominance of full shrub species based on a weighted average of the percent areal extent of all vegetation communities and their associated full shrub species present within the eligible land. In this instance, one shrub patch seed mixture will be developed for the entire 20 percent areal extent.

   3.  From the information calculated in step 2. above, identify the dominant premine full shrub species. This species then becomes the target postmine species within the postmine shrub patches.

   4.  Compute the minimum density that the postmining target shrub (identified in step 3. above) must meet in order to achieve bond release under the standard. This is accomplished by applying the following equation:

   D[1/(N + 1)]

   D is the postmining total shrub density (D is always < 1.00). N is the number of primary

   shrub species existing in the premining communities as identified in step 2. above. Primary shrub species shall be defined as full shrub species which comprise at least 10 percent of the relative density of full shrubs.

   All primary shrub species shall be included in the shrub patch seed mixture.

   5.  The postmining residual density is calculated by subtracting the minimum required density of the target species from the total required density.

   6.  Residual density may be comprised of any premining primary species and any other approved full shrub species. In addition, the following subshrub species may be counted towards up to one half of the residual density.

   Artemisia frigida fringed sagewort Atriplex gardneri/gordonii Gardners saltbush Ceratoides lanata winterfat Artemisia pedatifida birdfoot sagewort Artemisia spinescens bud sagewort For a hard copy of Figure 1: Tables 1 and 2 please refer to the copy on file with the Secretary of State or with the Wyoming Department of Environmental Quality.

   For an electronic copy of these tables please contact the Land Quality Division at 777-7757.

   For a hard copy of Figure 1: Table 3 please refer to the copy on file with the Secretary of State or with the Wyoming Department of Environmental Quality.

   For an electronic copy of this table, please contact the Land Quality Division at 777-7757 Option II: Permit-wide full shrub density standard, no reduction in areal extent or density, composition based on premining full shrub density only (see Figure 2 for an illustration of this Option).

   1.  If 20 percent or more of the premine eligible land supports at least 1 shrub per square meter, no reduction in shrub density or areal extent shall be permitted.

   2.  Compute the relative premining density of full shrub species based on a weighted average of the percent areal extent of all vegetation communities and their associated full shrub species present on eligible land. In this instance, one shrub patch seed mixture will be developed for the entire

   20 percent areal extent.

   3.  From the information calculated in step 2. above, identify the dominant premine full shrub species. This species then becomes the target postmine species within the postmine shrub patches.

   4.  Compute the minimum density that the postmining target shrub (identified in step 3. above) must meet in order to achieve bond release under the standard. This is accomplished by apply- ing the following equation:

   D[1/(N + 1)]

   D is the postmining total shrub density (D is always < 1.00). N is the number of primary shrub

   species existing in the premining communities as identified in step 2. above. Primary shrub species shall be defined as full shrub species which comprise at least 10 percent of the relative density of full shrubs.

   All primary shrub species shall be included in the shrub patch seed mixture.

   5.  The postmining residual density is calculated by subtracting the minimum required density of the target species from 1.00.

   6.  Residual density may be comprised of any premining primary species and any other approved full shrub species. In addition, the following subshrub species may be counted towards up to one half of the residual density.

   Artemisia frigida fringed sagewort Atriplex gardneri/gordonii Gardners saltbush Ceratoides lanata winterfat Artemisia pedatifida birdfoot sagewort Artemisia spinescens bud sagewort For a hard copy of Figure 2: Tables 1 and 2 please refer to the copy on file with the Secretary of State or with the Wyoming Department of Environmental Quality, Land Quality Division.

   For an electronic copy of Tables 1 and 2, please contact the Land Quality Division at 777-7757.

   For a hard copy of Figure 2: Table 3 please refer to the copy on file with the Secretary of State or with the Wyoming Department of Environmental Quality, Land Quality Division.

   For an electronic copy of Table 3, please contact the Land Quality Division at 777-7757.

   Option III: Community-specific full shrub density standard (see Figure 3 for an illustration of this Op- tion)

   1.  Each eligible premining vegetation community serves as the basis for developing the required postmine density and areal extent. The percentage each community contributes to the total eligible land is multiplied by 20 percent to establish the number of acres required on the postmining landscape. The average number of full shrubs each community supported premine serves as the postmine average density for that particular community.

   2.  Compute the relative premining dominance of all full shrub species within each eligible vegeta- tion community. In this instance, one shrub patch seed mixture will be developed for each eligible vegetation community.

   3.  From the information calculated in step 2. above, identify the dominant premine full shrub species within each eligible vegetation community. This species then becomes the target postmine species within a particular shrub patch corresponding to a specific vegetation community.

   4.  Compute the minimum density that the postmining target shrub (identified in step 3. above) must meet in order to achieve bond release under the standard. This is accomplished by apply- ing the following equation:

   D[1/(N + 1)]

   D is the postmining total shrub density (D is always < 1.00). N is the number of primary shrub

   species existing in the premining communities as identified in step 2. above. Primary shrub species shall be defined as full shrub species which comprise at least 10 percent of the relative density of full shrubs.

   All primary shrub species shall be included in the respective shrub patch seed mixtures.

   5.  The postmining residual density is calculated by subtracting the minimum required density of the target species within each vegetation community from the total required density for that community.

   6.  Residual density may be comprised of any premining primary species and any other approved full shrub species. In addition, the following subshrub species may be counted towards up to one half of the residual density within each community.

   Artemisia frigida fringed sagewort Atriplex gardneri/gordonii Gardners saltbush Ceratoides lanata winterfat Artemisia pedatifida birdfoot sagewort Artemisia spinescens bud sagewort For a hard copy of Figure 3: Tables 1 and 2 please refer to the copy on file with the Secretary of State or with the Wyoming Department of Environmental Quality, Land Quality Division.

   For an electronic copy of Tables 1 and 2, please contact the Land Quality Division at 777-7757.

   Option IV: Community-specific full shrub and approved subshrub density standard (see Figure 4 for an illustration of this Option)

   1.  Each eligible premining vegetation community serves as the basis for developing the required postmine density and areal extent. The percentage each community contributes to the total eligible land is multiplied by 20 percent to establish the number of acres required on the postmining landscape. The average number of full shrubs and approved subshrubs each community sup- ported premine serves as the postmine average density for that particular community.

   The following are the approved subshrubs which shall be included in calculating the premining density within each community:

   Artemisia frigida fringed sagewort Atriplex gardneri/gordonii Gardners saltbush Ceratoides lanata winterfat

   2.  Compute the relative premining dominance of full shrub and approved subshrub species within each eligible vegetation community. In this instance, one shrub patch seed mixture will be developed for each eligible vegetation community.

   3.  From the information calculated in step 2. above, identify the dominant premine full shrub or approved subshrub species within each eligible vegetation community. This species then be- comes the target postmine species within a particular shrub patch corresponding to a specific vegetation community.

   4.  Compute the minimum density that the postmining target shrub/approved subshrub (identified

   in step 3. above) must meet in order to achieve bond release under the standard. This is accomplished by applying the following equation:

   D[1/(N + 1)]

   D is the postmining total shrub density (D is always < 1.00). N is the number of primary shrub/approved subshrub species existing in the premining communities as identified in step 2.

   above. Primary shrub/approved subshrub species shall be defined as full shrub/approved sub- shrub species which comprise at least 10 percent of the relative density of full shrubs. How- ever, in order to be considered a primary species, fringed sagewort must comprise at least 20

   percent of the relative shrub/approved subshrub composition.

   All primary shrub/approved subshrub species shall be included in the respective shrub patch seed mixtures.

   5.  The postmining residual density is calculated by subtracting the minimum required density of the target species within each vegetation community from the total required density for that community.

   6.  Residual density may be comprised of any premining primary full shrub/approved subshrub species and any other approved full shrub species. In addition, the following subshrub species may be counted towards up to one half of the residual density within each community.

   Artemisia frigida fringed sagewort Atriplex gardneri/gordonii Gardners saltbush Ceratoides lanata winterfat Artemisia pedatifida birdfoot sagewort Artemisia spinescens bud sagewort For a hard copy of Figure 4: Tables 1 and 2 please refer to the copy on file with the Secretary of State or with the Wyoming Department of Environmental Quality, Land Quality Division.

   For an electronic copy of Tables 1 and 2, please contact the Land Quality Division at 777-7757.

   A complete proposal for evaluation of postmining shrub density should include:

   1. A commitment to provide a brief history of the methods employed to implant shrubs and the husbandry practices specifically related to shrub establishment and maintenance.

   2. Methods to identify shrub patches and to determine their areal distribution and extent.

   3. Proposed sampling methods for the determination of shrub density within the patches. This discussion should include number of samples.

   4. Proposed methods for documenting the presence and distribution of shrub species on all other lands jointly used by livestock and wildlife.

   F. Summary

   The major components of a complete proposal for evaluation of revegetation success should be presented in the Reclamation Plan and should include:

   1. A commitment to provide a brief discussion of the reclamation practices used on each reclaimed area, including the seed mix applied, any husbandry practices used (e.g., interseeding, biocide application, etc.) and the land management practices applied.

   2. A commitment to describe the procedures used to define the boundaries of each reclaimed area, including any combinations of different age classes of reclaimed areas.

   3. Presentation of the methods used to define the vegetational composition of each reclaimed area, such that the proper CONA may be chosen. Two approaches seem apparent:

   a.  The composition may be determined by a thorough, qualitative field reconnaissance.

   Qualitative means the use of methods which do not involve point sampling procedures

   as discussed in Section II. A.

   b.  The composition may be determined by standard, point sampling techniques. These data would subsequently be used in the direct evaluation of revegetation success.

   4. Specification of the actual methods employed for each vegetation parameter. The sampling procedures should use standard methods and should be based upon standard procedures for the choice of sample locations. Clearly, the same methods must be used on the reclaimed areas and CONA or REFA.

   5. Specification of the number of samples to be taken for each parameter from the reclaimed areas and CONA. Several options are available:

   a.  The applicant may employ the sample adequacy procedures of Appendix A, as quali- fied by maximum and minimum sample numbers.

   b.  The applicant may employ other standard, statistical tests for assessing sample ad- equacy.

   6. Specification of the statistical methods proposed for the comparison of quantitative vegeta- tion parameters.

   7. Specification of qualitative or quantitative (or a combination thereof) methods to assess the success standard that species diversity and species composition are capable of supporting the postmining land uses.

   8. Specification of methods to demonstrate that the reclaimed area is capable of withstanding grazing pressure at least comparable to that sustained prior to mining.

   9. Specification of methods to assess the establishment of suitable postmining wildlife habitat, including assessment of the quantitative and qualitative aspects of wildlife habitat.

   Only one plant species in Wyoming is currently listed as Threatened (T) or Endangered (E) under the federal Endangered Species Act. Three other species are candidates (C) for potential listing. These plants are noted by their assigned ranking in parentheses. However, there are many additional species occurring within Wyoming which may be considered for formal listing in the future. State and federal agencies have historically afforded these species special consideration until their status is accurately assessed.

   Presented below are those species currently (as of January, 1998) listed as Threatened (T), Endan- gered (E), or Candidates (C). In addition to this list, the Administrator will compile a list of those species that deserve special consideration. This list will be made available to the public and will be updated as determined by the Administrator.

   Appendix VII - Glossary

   “Absolute Cover” is the determination of % cover of a given cover category in a fashion which is operationally independent of the other categories. Thus the sum of absolute cover categories (e.g.

   vegetation and litter/rock and bare ground) may be less than, equal to or greater than 100% (see Relative Cover).

   “Affected Land” (Affected Area) means the area of land from which overburden is removed, or upon which overburden, development waste rock or refuse is deposited, or both, access roads, haul roads, mineral stockpiles, mill tailings, impoundment basins, and all other lands whose natural state has been or will be disturbed as a result of the operations.

   “Adjacent Areas” means land located outside the permit area upon which air, surface water, ground- water, fish, wildlife, or other resources protected by the Act may reasonably be expected to be ad- versely impacted by mining or reclamation operations. Unless otherwise specified by the Administra- tor, this area shall presumptively be limited to lands within one-half mile of the proposed permit area.

   “Baseline Vegetation Inventory” is a vegetation sampling program executed prior to any significant surface disturbance caused by proposed mining activities. The inventory will provide a verbal and mental picture of the prevailing plant communities and will quantitatively and qualitatively classify the different plant communities to the specifications of Wyoming State Law.

   “Comparison Area” means a land unit which is representative, in terms of physiography, soils, veg- etation and land use history, of a premining plant community from which no vegetation data were collected prior to disturbance. The representative nature of the Comparison Area may be validated by a subjective field reconnaissance of the site or by subjective evaluation of vegetation data generated by a sampling program. The establishment procedures should be agreed to by the permittee or applicant and LQD prior to establishment.

   Postmining quantitative data from the Comparison Area are directly compared, by standard statistical procedures (confidence level of 80%, “ = 0.2), to data from a reclaimed vegetation type when evalu- ating revegetation success for full bond release. No mathematical adjustment for climatic change is made. Qualitative data are compared by standard procedures agreed to by the applicant or permittee and LQD.

   A Comparison Area should be at least two (2) acres in size and should be managed in a fashion which will not cause significant changes in vegetation parameters used to evaluate revegetation success.

   “Control Area” means a land unit which is representative in terms of physiography, soils, vegetation and land use history, of a plant community affected by mining activities. The representative nature of the Control Area is verified by subjective (non-statistical) comparison of its quantitative and qualita- tive characteristics to similar information from the plant community it typifies.

   Quantitative premining and postmining vegetation data from the Control Area are used to mathemati- cally adjust premining affected area data for climatic change. These adjusted data are directly com- pared by statistical procedures (confidence level = 80%, “= 0.2) to data from a reclaimed vegetation type when evaluating revegetation success for full bond release. Qualitative data are compared by standard procedures agreed to by the applicant or permittee and LQD.

   A Control Area should be at least two (2) acres in size and should be managed in a fashion which will not cause significant changes in the vegetation parameters used to evaluate revegetation success.

   “Cool-Season Plant” is a species which grows and flowers during the spring. Its growth usually slows or becomes dormant during the hotter, drier portions of the summer, but the species may re- sume growth in the fall with the advent of cooler temperatures and available soil moisture.

   “Cover” is the proportion of the ground surface cloaked by a vertical projection of objects on or above that ground surface. Cover is expressed as a percentage of a surface reference unit. The following cover categories are of interest to LQD:

   1.  % litter and rock cover is the proportion of the ground surface overlain by dead plant mate- rial and rock (defined as any stone or mineral matter at least one (1) square centimeter in size).

   2.  % vegetation cover is the vertical projection of the general outline of plants (ignoring minor gaps between branches and holes in the canopy) to the ground surface.

   3.  % total ground cover is the sum of the cover values for % vegetation, % litter and % rock.

   4.  % bare ground is the proportion of the ground surface occupied by unvegetated mineral soil.

   “Cropland” means land used for the production of adapted crops for harvest, along or in a rotation with grasses and legumes, and includes row crops, small grain crops, hay crops, nursery crops, orchard crops, and other similar specialty crops.

   “Density” is the number of individuals per unit area.

   “Dominant” refers to the species with the greatest density relative to all other species sampled.

   “Extended Reference Area” means all the undisturbed portion of a vegetation type which has experi- enced disturbance by mining activities. The representative nature of the Extended Reference Area is verified by evaluation of vegetation mapping procedures, the adequacy of premining quantitative and qualitative vegetation data, soils data, physiography and land use history information.

   Postmining quantitative vegetation data from the Extended Reference Area are directly compared by standard statistical procedures (confidence level of 80%, “= 0.2) to data from a reclaimed vegetation type when evaluating revegetation success for full bond release. No mathematical adjustment for climatic change is made. Qualitative data are compared by standard procedures agreed to between the permittee and LQD.

   An Extended Reference Area should be managed in a fashion which will not cause significant changes in vegetation parameters used to evaluate revegetation success.

   “Forestry” means land used or managed for the long-term production of wood, wood fiber, or wood derived products.

   “Full Shrub” is a perennial woody plant which differs from a tree by normally being shorter in height and by often having several stems arising near the base.

   “Grazing Exclosure” is a fence or other device utilized to prevent grazing by large herbivores in order to more accurately estimate production of a land unit.

   “Grazingland” includes rangelands and forest lands where the indigenous native vegetation is actively managed for grazing, browsing, or may occasionally be cut for hay production.

   “Land Use” refers to the specific uses or management-related activities which a given unit of land experiences. Land use is directly supported by, but not directly defined by the existing plant commu- nities. See definitions of cropland, pastureland, grazingland, forestry, or appropriate discussion in LQD Rules and Regulations, Chapter 1, under “land use.”

   “Life Form” is a category of growth morphology which appears to have some adaptive significance.

   Examples of life forms include trees, full shrubs, sub-shrubs, perennial grasses, annual forbs, succu- lents, cushion plants, etc.

   “Line Intercept” is a cover estimation method based upon the measurement of the proportion of a line transect intercepted by the vertical projection of plant parts. Absolute cover, when using the line intercept method, is defined by the formula

   % cover of A = sum of all segments intercepted by A x 100

   total length of the line transect

   “Litter” means any recognizable plant parts or structures which are lying on the ground surface.

   Decomposing organic matter which has lost its structural integrity or which is no longer a recogniz- able plant part is not litter.

   “Noxious Weeds” are agriculturally unuseful or troublesome plants whose seeds are totally prohibited from or severely limited in any amounts in commercial crop seed offered for sale. These designations are made by State law.

   “Prohibited noxious” (designated) weeds are those species whose seed is not allowed in the seed of crops under any amounts. Restricted noxious (designated) weeds are those species whose seed is tolerated in the seed of crops only under small amounts. Declared weeds are those species which are of a particular concern to a specific county which may or may not be considered noxious (designated) under State law.

   “Pastureland” is land used primarily for the long-term production of adapted, domesticated forage plants to be grazed by livestock or occasionally cut and cured for livestock feed.

   “Permit Area” means the area of land and water within the boundaries of the approved permit or permits during the entire life of the operation and includes all affected lands and water.

   “Plant Community” (Vegetation Type) is a relatively homogeneous combination of individual plants existing under common environmental conditions.

   “Plotless Sampling” means estimation of vegetation parameters without the use of two-dimensional areal reference units.

   “Point Intercept” is a cover estimation method based upon the lowering of a “pin” through the vegeta- tion at objectively established sampling points. The “pin” may be an ocular siting device (e.g.

   crosshairs), a sharpened rod or a series of sharpened rods. Absolute cover, when using the point intercept method, is defined by the formula:

   % cover of A = number of hits on A x 100

   total number of hits

   “Primary shrub species” means all full shrub species which comprise at least 10 percent of the relative density of full shrubs. However, if an operator selects Option IV, the community-specific full shrub and approved subshrub density standard, then “primary shrub species” means all full shrub and approved subshrub species which comprise at least 10 percent of the relative density of full shrubs. It is further provided under Option IV that in order to be considered as a “primary shrub species”, fringed sagewort must comprise at least 20 percent of the relative shrub and approved subshrub species composition.

   “Production” is an estimate of the total standing crop biomass of herbaceous species (grass, grass- like, forb and some subshrub species). The estimate is made at a time near the expected peak of the current year’s growth and is reported on a per unit area basis.

   “Quadrat” is a two-dimensional areal unit which is superimposed on the ground surface for the pur- poses of estimating one or more vegetation parameters.

   “Reference Area” means a land unit which is representative, in terms of physiography, soils, vegeta- tion and land use history, of a plant community affected by mining activities. The representative nature of the Reference Area is verified by statistical comparison (confidence level of 90%, “ = 0.1) of its absolute values of % vegetation cover, % total ground cover and total herbaceous production to similar data from the plant community it typifies. Species composition and species diversity are also subjectively (non-statistically) evaluated.

   Postmining quantitative vegetation data from the Reference Area are directly compared by standard statistical procedures (confidence level of 80%, “ = 0.2), to data from a reclaimed vegetation type when evaluating revegetation success for full bond release. No mathematical adjustment for climatic change is made. Qualitative data are compared by standard procedures agreed to between the permit- tee and LQD.

   A Reference Area should be at least two (2) acres in size and should be managed in a fashion which will not cause significant changes in the vegetation parameters used to evaluate revegetation success.

   “Relative Cover” is the expression of any number of cover categories e. g.vegetation + litter/rock + bare ground) in relation to each other, such that the sum of the relative cover values for those catego- ries totals 100%. Relative Cover is calculated by the formula:

   % Relative Cover of A = Absolute Cover of A x 100

   Sum of the Absolute Cover of categories A + B + ...n

   “Selenium Indicator Plants” are plant species which may selectively concentrate selenium in their tissue and/or be tolerant of high selenium concentrations in the soil. These species, when grazed by cattle or sheep, may produce toxic reactions known as selenium poisoning.

   “Shrub Mosaic” is a pattern of shrub patches designed to achieve maximum habitat interspersion and edge effect. The boundary of a mosaic encompasses the areal extent of shrub patches and other vegetation types occupying the area between the patches.

   “Shrub Patch” refers to a continuous surface of varying shape and size (no less than 0.05 acres) that is intensively managed to support a high density of shrubs.

   “Species Composition” means number, kinds, amount, and quality of species.

   “Species Diversity” means number of species per unit area.

   “Study Area” means the full extent of the surface area which was sampled during the baseline vegeta- tion inventory. The study area may coincide with or exceed the permit area.

   “Subshrub” is a perennial plant which is partly woody, usually at the base, but also partly herbaceous.

   The individual plant generally dies back to the woody tissue after each year’s growth.

   “Transect” is a sampling method which involves the establishment of a long, continuous line or strip.

   The starting point and orientation of the line should be randomly established.

   “Warm-Season Plant” is a species which produces most or all of its growth during the late spring and summer, subsequently flowering in the late summer or autumn.

   APPENDIX B

   WILDLIFE MONITORING REQUIREMENTS FOR SURFACE COAL MINING OPERATIONS INTRODUCTION

   Procedures specified in this Appendix are required for surface coal mining operators per Chapter 2, Section 2(b)(vi)(B) and Chapter 4, Section 2(r)(iv) of the WDEQ/LQD Rules and Regulations.

   The requirements herein shall become effective January 1 following filing with the Wyoming Secretary of State. The monitoring procedures specified in this Appendix are applicable to sur- face coal mines. Operators disturbing less than 640 acres of land may request a reduced level of monitoring through submittal of a wildlife monitoring plan to be reviewed and approved by the regulatory authority prior to implementation.

   Permission for significant departures from this Appendix shall be requested by formal proposal to the LQD. Proposed alternatives will be reviewed by the appropriate wildlife agencies prior to approval and implementation. Alternative methods which are equally effective as those recom- mended in this Appendix will be given due consideration and may be approved by the Administra- tor. Specific procedures in this Appendix may be waived by the Administrator where the operator affirmatively demonstrates that the impact cannot occur or is not a reasonable concern during the life of the mine. The type and amount of monitoring may be modified depending upon the wildlife species and habitats on and adjacent to the permit area, the size of the area to be affected over the mine life, and site-specific problems.

   Operators with overlapping monitoring areas shall coordinate their monitoring programs to eliminate duplication. Though not required, operators should consider coordinated and consoli- dated monitoring efforts with neighboring mines in order to assure the collection of meaningful and comparable data. Qualified wildlife professionals must be utilized for the collection and analysis of data in order to assure accuracy and consistency. Each mine's annual report to the LQD shall include the monitoring data and analysis specified by this Appendix. Data compari- sons should consider all years since the onset of data collection, though only the data for the cur- rent year and the four previous years need be presented in the annual report. Data analysis procedures and standardized reporting shall be in a form acceptable to the Administrator. The Administrator will strive to ensure the timely review of wildlife monitoring data provided in annual reports to the LQD and the cumulative analysis of monitoring data from all operators.

   A. Big Game Seasonal Habitat Use

   Seasonal Distribution and Habitat Affinity

   One aerial survey and one ground survey shall be conducted between January 1 and mid-March each year. Aerial surveys are primarily for pronghorn and ground surveys for deer. However, all big game should be recorded in all surveys. The ground survey shall be conducted as soon as practical after the aerial survey. The aerial survey should be conducted on a clear day with 100 percent snow cover (optimum conditions). Where actual snow cover conditions deviate from the optimum due to areas continually blowing free of snow, it would be acceptable to conduct the survey with less than 100 percent snow cover (but not less than 80 percent snow cover).

   Deviation from optimum conditions reduces data quality and, therefore, the operator should use discretion in selecting the best survey conditions. Aerial surveys shall be conducted at constant altitude from a light, high wing aircraft with one or two observ- ers. The survey area shall be covered by flying north-south transects spaced at 1/2

   mile intervals if there is one observer or 1 mile intervals if there are two observers.

   If appropriate snow cover conditions have not developed by the first of March, the aerial survey shall then be conducted either under minimal snow cover conditions (0-

   20 percent) or near complete (80-100 percent) snow cover. Again, the operator should use discretion in selecting appropriate survey conditions. If neither of these snow cover conditions develop by mid-March, the aerial survey should not be con- ducted for that year and only the ground survey would be necessary. In addition to the winter surveys, one ground survey shall be conducted in April, early June and August; all big game should be recorded in these surveys. Surveys shall cover the permit area and 2 mile perimeter. Ground routes should allow visual coverage of the entire study area, and the same routes must be utilized each survey to the extent possible.

   Climatological Information

   The relative severity of each winter must be determined to evaluate how big game respond to mining and reclamation during average to extreme winter conditions. A daily weather record (snow depths, minimum and average temperatures, wind veloci- ties) must be obtained from the nearest NOAA weather station or a continuous re- cording station on or near the permit area. Data must cover the period from Novem- ber through mid-March and must be provided to the LQD in each annual report.

   Additionally, each mine must note snow cover trends preceding the winter aerial survey. Areas where deep snow persistently accumulates, covering forage and/or precluding big game movement, must be sketched on a map.

   Range Conversions

   Each mine operator shall obtain seasonal range maps from the Wyoming Game and Fish Department (WGFD) for big game species present on the permit area. Range delineations must be superimposed on a mine plan map and the total area affected over the mine life must be calculated and the incremental amount affected each year reported.

   Mortalities and Concentration Buildups

   Each mine operator must maintain a record of big game mortalities including fence entanglements, vehicular collisions, and other deaths. Winter mortalities shall be estimated each spring from observations incidental to surveys and other mine activi- ties. Species, date, and probably cause of mortality should be recorded, and a cumu- lative record must be submitted in each annual report.

   Any sudden concentration buildups or apparent migration blocks must be reported immediately to local WGFD personnel and should be described in each annual report.

   B. Upland Gamebird Brood Counts and Lek Attendance Surveys

   Lek Searches

   All suitable lek habitat on the term of permit area and a one-mile perimeter must be searched for new leks at least once each spring. Every third year, searches must cover the entire permit area and its one-mile perimeter. Lek searches shall be conducted from late March through April by driving roads and stopping frequently (at no greater than one mile intervals) to scan and listen for displaying sounds. During annual attendance surveys at known leks, any new leks discovered shall be noted.

   Complete coverage must be achieved by ground surveys. Aerial surveys are ineffec- tive for sharptail grouse leks, but may be used to augment ground surveys for sage grouse leks. Searches shall be conducted between dawn and 1 hour after sunrise.

   When display or breeding activity is noted at a site during a lek search, that site must be checked two more times during the breeding season.

   Lek Attendance Surveys

   At each known lek, a minimum of three attendance counts must be conducted during April through early May. Attendance counts shall be conducted from 1/2 hour before to 1/2 hour after sunrise, separated by 7 to 10 day intervals. Peak male attendance shall be determined using repeated counts until the observer is confident in the count.

   The number of females observed shall also be recorded. Each annual report must include a complete record of the status and history of all leks, including those which have been destroyed or have become inactive.

   Brood Habitat Surveys

   Permanent walking routes shall be established along edges of all native drainages, subirrigated meadows, and other mesic sites within the permit area, totalling up to

   3,000 meters (1.86 mi.). Similar transects totalling up to 3,000 meters shall be estab- lished on reclamation as soon as revegetated bottomlands and drainages become available. During July each year, all routes shall be surveyed twice within a week period. Weather conditions should be calm, clear, and dry. All grouse observed shall be classified as adult males, adult females, or juveniles. Results must be expressed as number of individuals observed per 1,000 meters. Although transects within native habitats will be eliminated as mining progresses, results prior to disturbance will establish baseline brood densities. These will afford a basis for evaluating grouse recovery on reclaimed surfaces.

   Measures of Disturbance

   To evaluate effects of visual and auditory disturbance, operators shall measure the linear distance from each lek to the closest known, regular human or equipment activity during each breeding season. The presence or absence of direct line of sight must also be noted. Habitat alteration must be calculated annually as the cumulative disturbed acreage of each habitat type and the cumulative acreage of permanent reclamation (classified as upland or bottomland).

   C. Raptor Production

   Nest Status and Production Success

   On or before mid-February, surveys for golden eagle and great horned owl nests shall be initiated within ½ mile of existing mining activities and those activities proposed for the coming year. It is advantageous to document early courtship behavior in potential conflict situations because once eggs are laid, mitigation options become restricted.

   In addition, three thorough surveys covering the entire permit area and a one mile perimeter must be conducted within the following time frames. The first shall be conducted during March to locate golden eagle and great horned owl nests. A second survey shall be conducted in April to locate nests of most other species. A third survey shall be conducted from mid-May through mid-June to locate new raptor nests and to check the status of all known nests.

   Follow-up visits to previously identified nests, as necessary, shall be timed to facili- tate documentation of occupied territories, nest building, incubation and fledging success according to the biology of the species present and variations in breeding chronology among study areas.

   Nest checks during all periods should be brief and conducted from a distance to avoid flushing incubating raptors from their nests. Once an active nest is identified, produc- tivity checks shall be conducted to determine the number of young fledged from the nest. The status and productivity of all nests are to be reported annually.

   Measures of Disturbance

   The linear distance of each nest site (active or not) from the nearest known, regular human or equipment activity must be determined each breeding season. Note must be made whether a direct line of sight exists between the nest and the activity (recorded as presence or absence of visual barrier). If the nearest activity is unrelated to mine operations, this should be noted. A record of all nests, including those which have been destroyed, and their histories must be updated and submitted annually. Deterio- rated nests which are not in reusable condition should also be indicated. All nest locations must be shown on a wildlife monitoring map.

   Prey Abundance Indices: Lagomorphs

   Lagomorph monitoring shall be accomplished with either walking or driving transects of sufficient length to achieve an adequate sample. Consistent methods must be maintained over all areas surveyed, and over time. As representative acreages of different reclamation types become available, additional transects shall be established in these types.

   Permit Term Mitigation Plan

   Prior to permit approval and each subsequent renewal or major amendment or revi- sion, the operator must consult the U.S. Fish and Wildlife Service (USFWS) to develop (or update) a raptor management plan. The outcome of this consultation, along with a USFWS letter of approval, shall be included within the application document. The "take" of a raptor nest with eggs or young should be considered only when no other alternative exists and after obtaining a special purpose permit from the USFWS and the necessary scientific permit from the WGFD. Results of monitoring and mitigation stipulations shall be included in applicable annual reports to the LQD.

   D. Migratory Birds of High Federal Interest

   Surveys for Migratory Birds of High Federal Interest (MBHFI) must be conducted in accordance with the operator's MBHFI plan as approved by the USFWS. Date and location of each MBHFI sighting, as well as habitat and activity, must be reported to the LQD in annual reports.

   E. Federally Listed Threatened and Endangered Species

   All observations of threatened and endangered species must be reported promptly to the regulatory authority as required in Chapter 4, Section 2(r)(i)(E), unless otherwise specified by the USFWS.

   Bald Eagles

   If a bald eagle roost occurs on the permit area or within accessible portions of a one- mile perimeter, three counts of eagle attendance at the roost must be made from January through mid-March. Roost counts must be separated by at least two weeks.

   If suitable roost habitat (large riparian tree groves, wooded canyons) occurs on or near the permit area, one annual survey for new roosts must be conducted in January or February. Coverage must include the permit area and one-mile perimeter. Searches must be started at dawn and end no later than two hours after sunrise. These searches can be conducted by personnel on the ground or from a light airplane.

   Results or roost counts and searches must be reported to the LQD and locations of roosts must be shown on a wildlife monitoring map.

   Black-footed Ferrets

   Searches for black-footed ferrets will be limited to prairie dog colonies on the permit area. A search must be conducted within one year before beginning disturbance of a colony. Ferret searches must be led by an individual certified by the USFWS. Proce- dures described in the BLM Handbook of Methods for Locating Black-Footed Ferrets and the most recent USFWS guidelines must be followed. Prior to conducting a search, the USFWS Regional Endangered Species Office must be contacted to verify procedures.

   Results of each survey must be submitted to OSM and USFWS for review and clear- ance. A copy of survey results must be sent to the WDEQ/LQD for review. Copies of ferret survey reports and associated correspondence must be included in the annual report to the LQD.
