The Southern Sierra Nevada Fisher Conservation Assessment and Strategy is a multi-agency effort to conserve and recover an isolated and imperiled population of Pacific fisher (Pekania pennanti) in the southern Sierra Nevada, California. CBI is collaborating with The Fisher Interagency Leadership Team (Sierra Nevada Conservancy, USDA Forest Service, National Park Service, US Fish and Wildlife Service, and California Department of Fish and Wildlife) to develop the Assessment, Strategy, and associated decision-support tools with funding provided by Sierra Nevada Conservancy (SNC), the USDA Forest Service (Pacific Southwest Region), Resources Legacy Fund, and the US Fish and Wildlife Service (USFWS).

The Conservation Assessment summarizes information about fishers in the southern Sierra Nevada, including population size, distribution, and trends; ecology; habitat requirements across multiple spatial scales (from the population or landscape scale to the scale of individual denning or resting structures); and threats to fishers and their habitat. It is a focused review of information most relevant to crafting a strategy to conserve the population in the southern Sierra Nevada. This assessment provides the biological and ecological foundations for a Southern Sierra Nevada Fisher Conservation Strategy and a Decision Support System to help implement that Strategy.

The Southern Sierra Nevada Fisher Conservation Strategy provides science-based guidance for reducing threats and increasing the quality and resiliency of fisher habitat. The strategy is based on the best available scientific information on fishers and their habitats in the area (as summarized in the Southern Sierra Nevada Fisher Conservation Assessment). The Strategy is intended to meet the needs of multiple agencies with an interest in fisher conservation and land management in the Sierra Nevada. As such, the Strategy is intended to be compatible with diverse agency missions, objectives, and legal requirements.
