APPENDIX D – SUMMARY OF BIOLOGICAL EVALUATIONS FOR WILDLIFE, 

FISHERIES, AND BOTANICAL RESOURCES IN THE PACTOLA PROJECT AREA 

This document is a synthesis for the Wildlife and Fisheries Resource in the Pactola Project Area. 

The summary is an effort to reduce redundancy and improve reading ease while retaining important 

content. It is not intended to meet all the legal requirements and policies associated with the BE. 

The parent BE is contained in the Pactola Project administrative record. 

The main purpose of a BE is to disclose, in detail, the potential effects of all alternatives to 

federally-listed and Forest Service sensitive species.1 The BE also provides a “determination 

statement” to help decision-makers and other readers see how the project might affect the longterm persistence of a species. This summary document provides simplified effects disclosures 

and determination statements for all species relevant to the Pactola Project Area, and provides 

the reader with some of the information sources used in the analyses. 

Pre-field Review and Field Reconnaissance 

Pre-field review and field reconnaissance are essential in determining which species could occur 

in a project area, and how they might be affected. Pre-field reviews were completed using past 

survey results, district records, literature reviews, on-line databases, and Forest Plan monitoring 

reports. Field visits were performed with intent to identify suitable and/or occupied habitat for 

sensitive species. These surveys were conducted by qualified biologists, including Forest Service 

employees and contractors. In addition to species-specific surveys, additional field visits to the 

Pactola Project Area were conducted with the general intent of identifying habitat and potential 

issues for other status species. Data from all sources mentioned above were used to determine 

design criteria needs and effects relevant to the Pactola Project Area. 

Effects and Associated Determination Statements for Relevant Species 

The parent BE discloses the full set of federally-listed and sensitive species that are known to 

occur on the Black Hills National Forest (BHNF). The BE also identifies which of those species 

potentially have habitat within the Pactola Project Area. This latter subset of species are 

considered relevant to the Pactola Project Area, and are the main subject of this summary as well 

as the detailed analyses in the BE. The assumption is that if habitat is present, the species could 

be present and be affected by project activities. Project activities can directly impact most 

individual sensitive species in all alternatives. Indirectly, MPB infestations would likely affect 

sensitive wildlife species (positive and negative) in Alternative A by changing mature/late 

successional pine habitat to a more open habitat, increasing snags and down woody material and 

increasing the potential for large-scale wildfire. Alternatives B and C treatment actions increase 

the chance of direct and indirect effects on most sensitive species (individuals) as compared to 

Alternative A. The action alternatives reduce MPB and wildfire hazard by moving dense 

mature/late successional pine habitat to more open, early seral habitat through proposed

 Federally-listed species are those that have been designated by the US Fish and Wildlife Service as endangered or 

threatened (i.e., under the Endangered Species Act), including those that have been formally proposed for listing. 

Sensitive species are designated by the Regional Forester. Both categories imply rareness or sensitivity to 

management actions. 
Appendix D Pactola Project Area Summary BA/BE Wildlife, Fisheries, and Botany D - 4 

treatments. These treatments may provide both positive and/or negative effects to sensitive 

species to varying degrees based on each alternative. 

There are no federally-listed species with potential to occur in the Pactola Project Area. No 

“critical habitat” has been designated for any species on the BHNF. Therefore consultation is 

not required with the US Fish and Wildlife Service. 

There are nineteen R2 sensitive wildlife and fish species that have suitable habitat within the 

Pactola Project Area. Comprehensive effects analyses were provided for all of these species in the 

parent BE. A list of the species, description of their habitats, basic effects of the project, and their 

project-specific determination statements are summarized in Table 1 below. The determination 

statements primarily reflect the most aggressive combination of management activities (e.g., 

number of acres treated). Implementation of a less aggressive combination of activities would 

likely have a lesser effect, but usually result in the same determination. Therefore, only one 

determination statement is given here, and is intended to apply to alternatives.

Appendix D Pactola Project Area Summary BA/BE Wildlife, Fisheries, and Botany D - 17 

Possible determinations for sensitive species are 

• No impact; 

• Beneficial impact; 

• May adversely impact individuals, but not result in a loss of viability in the project area, 

nor cause a trend toward federal listing; and 

• Likely to result in a loss of viability in the project area, or in a trend toward federal listing. 

Region 2 sensitive species that may have suitable habitat somewhere on the BHNF, but not 

within the Pactola Project Area, are listed in the parent BEs. Comprehensive analyses and 

determination statements are not necessary for this latter group of species because there is no 

potential that the project would affect them. If habitat is not available, it is very unlikely that the 

species would be present or affected.

Forest Service Sensitive Species – Plants 

The determination of effects for action alternatives (Alternatives B and C) on Region 2 sensitive 

species in this BA/BE were made as the result of the information gathered in the pre-field 

review, field reconnaissance, survey results, and effects analysis for all action alternatives. The 

basis for these determinations was potential habitat, distribution, and effects from proposed 

activities. The determination language is set forth in Forest Service Manual 2670.

Objectives, standards, and guidelines have been identified in the Forest Plan Phase II to conserve 

Region 2 sensitive species found on the Black Hills National Forest (USDA Forest Service 

2005a). This project will follow the objectives, standards, and guidelines that are applicable to 

those species and habitats found in the Pactola Project Area. 

The project area was surveyed for Region 2 sensitive plants species and one occurrence (prairie 

moonwort) was confirmed. For most species with identified suitable but unoccupied habitat 

within the project area (foxtail sedge, yellow lady’s slipper, trailing clubmoss, large round-leaf 

orchid, sage willow, autumn willow, sphagnum moss, and great-spurred violet) habitat is

generally located in small areas not designated for mechanical treatments (drainages and 

wetlands) and is limited within the project area. Species with undefined suitable habitat (prairie 

moonwort and narrowleaf grapefern) appear to require a certain amount of historical disturbance 

to establish. Activities such as road construction and prescribed broadcast burning may generate 

the disturbed environment required for establishment. Although negative impacts to ponderosa 

pine habitats and unknown suitable habitat types are possible, they are outweighed by the longterm beneficial effects of reducing the risk of unnaturally intense wildfires in the future. The 

various methods of treatments designed to reduce fuel loading within the project area could help 

prevent the occurrence of a large scale wildfire and the resulting effects on suitable sensitive 

plant habitat types both within and adjacent to the project area. 

With implementation of the Forest Plan Phase II Amendment and all of the standards and 

guidelines adopted therein, and project specific design criteria, a determination of “May 

adversely impact individuals, but not likely to result in a loss of viability on the planning area, 
Appendix D Pactola Project Area Summary BA/BE Wildlife, Fisheries, and Botany D - 18 

nor cause a trend to federal listing or a loss of species viability range-wide” is made for the
