Summary of Effects on R2 Sensitive Species<br />

Little preferred spruce habitat is contained within the project area. The proposed<br />

action would retain more dense, mature habitat than the No Action alternative.<br />

However, the proposed action proposes treatments to improve stand health and<br />

reduce the risk of wildfire, thus, retaining more acres of dense, mature trees for<br />

connectivity. The proposed action contributes to conservation of marten habitat<br />

(Forest Plan Objective 221).<br />

The proposed action would meet these standards and guidelines. Fire suppression<br />

during the last century has allowed spruce to increase in abundance and density in<br />

the Black Hills. The Forest is conserving habitat for the American marten (USDA<br />

Forest Service 2010). Therefore, this species is likely to persist on the Forest.<br />

Proposed Action<br />

Direct and Indirect Effects<br />

Expected MPB activity would create No direct effects are expected. Individuals<br />

snags for roosting by killing large may be displaced temporarily.<br />

trees; these snags are expected to Mountain pine beetle are expected to kill<br />

remain for only five years. Potential large trees creating snags for roosting, but to<br />

long-term future roosting trees would a lesser degree than No Action. Therefore,<br />

be reduced due to MPB caused the potential to maintain large trees for<br />

mortality of large trees.<br />

future roosting sites is improved over No<br />

Action.<br />

Cumulative Effects<br />

Cumulative effects expected MPB Incremental impacts to habitat quantity are<br />

impacts from disturbance and from MPB<br />

activity killing roosting trees.<br />

Summary<br />

Both alternatives would have ‘no impact’ on the bald eagle.<br />

This project would be implemented consistent with any of the relevant standards,<br />

guidelines that protect bald eagles or provide for eagle habitat, and contributes to<br />

Objective 221.<br />

Alternative 2<br />

Proposed Action<br />

Alternative 1<br />

No Action<br />

No direct effects. Expected MPB<br />

activity would reduce nesting<br />

habitat, but increase foraging<br />

habitat. High fire hazard remain<br />

and is a threat to suitable nesting<br />

habitat. Some prey species would<br />

benefit by increasing grasses and<br />

forbs (cover and food source) or<br />

young-forest conditions, while other<br />

prey species that favor a mature<br />

over-story may decrease.<br />

Past timber harvest has contributed<br />

to the loss of large mature trees, and<br />

blocks of mature, dense forested<br />

stands have been reduced in size so<br />

that they are no longer considered<br />

Direct and Indirect Effects<br />

No direct effects to known nests, potential<br />

for direct effects to unknown nests. Would<br />

enhance and protect goshawk nesting areas<br />

by reducing MPB risk and fire hazard.<br />

Would retain more suitable nesting habitat<br />

than No Action. Increase in foraging habitat.<br />

Some prey species could be adversely<br />

affected as well by removing canopy, snags,<br />

down woody material and ground cover.<br />

Similar impacts to prey species as No Action.<br />

Cumulative Effects<br />

Past timber harvest has contributed to the<br />

loss of large mature trees, and blocks of<br />

mature, dense forested stands have been<br />

reduced in size so that they are no longer<br />

considered large enough to meet the nesting<br />
