I assume the shitheads you are referring to is Unite the Parks and their recent lawsuit against the Forest Service challenging the the conservation plan for the Southern Sierra Nevada Pacific fisher, which was listed as an endangered species in May 2020. The fisher's habitat includes Sierra, Sequoia, and Stanislaus National Forests.
Unite the Parks argument is that the Forest Service is using fisher population data from pre-2011 studies, and failed to obtain new data after the 2020 fire season, which substantially reduced the fisher habitat (and likely fisher population). The Forest Service did conduct a review of their already-approved projects after the 2020 fires, but did not modify any of the projects. Also, the review conducted after 2020 fires still relied on data from pre-2011 studies, and was therefore flawed, according to Unite the Parks.
Unite the Parks points out that Forest Service agrees that removal of large trees and structural elements through logging, hazard logging, logging roads, and other vegetation management activities decreases the quality of den and rest sites and/or increase travel distances between safe sites even if den or rest structures themselves are not removed and may expose fishers to predation from mountain lions, bobcats, and coyotes. However, at the same time, the Forest Service argues that logging and other vegetation management activities also create potential positive effects by increasing habitat heterogeneity and promoting tree clumps and gaps within a stand, thereby increasing the resilience of these stands (Unite the Parks says the Forest Service cites no scientific evidence to support this). The Forest Service concedes that these projects may result in short-term impacts to fisher (through habitat modification or noise disturbance) but because many of the proposed projects are intended to reduce fuels and the risk of high-severity fires the Forest Service expects that these short term impacts are outweighed by the long-term benefits of these projects (again, Unite the Parks contends the Forest Service lacks scientific evidence to support this conclusion).
Unite the Parks main argument is that if the Forest Service is going to make the above conclusions, they need to go out and obtain new data on the fishers and not rely on data and studies pre-2011 to base their conclusions. The fisher population and habitat pre-2011 was very different than the fisher population and habitat today.
