Pacific Fisher Suitable Habitat

The Pacific fisher population in the southern Sierra is federally listed **** as a threatened population and resides primarily on National Forest System lands. Habitat management for this species is determined based on a Conservation Strategy developed by the US Forest Service and augmented by a recovery strategy developed by the US Fish and Wildlife Service. This species is found in the Northern California and Sierra Nevada Regions.

creation_method CWHR classifications are based on a combination of FVEG 2023 for canopy cover, size class and vegetation type. The vegetation data includes a variety of tree, shrub, grassland, and water dominated habitats. Species are considered present, and habitats considered suitable for each 30m cell for which the canopy cover-size-vegetation combination have been deemed suitable for the reproduction or foraging of that species in the California Wildlife Habitat Relationship database. Suitable habitat for the Pacific fisher is based on CWHR moderate and high suitability habitat for denning (reproduction) and foraging. CWHR suitability values were used to create a data layer that separately identifies suitable denning and suitable foraging habitat which meets the following criteria: * Suitable foraging vegetation types: WHRTYPE = DFR, EPN, JPN, MHC, MHW, MRI, PPN, SMC, WFR, RFR, LPN * Suitable foraging habitat: size/density classes = 4M, 4D, 5M, 5D, 6 * Suitable denning vegetation types: WHRTYPE = DFR, EPN, JPN, MHC, MHW, MRI, PPN, SMC, WFR * Suitable denning habitat: size/density classes = 4D, 5M, 5D, 6 The combined (denning and foraging) suitable habitat layer has been further refined and clipped to the U.S. Fish and Wildlife Service species range extent from the Environmental Conservation Online System (ECOS) available at <https://ecos.fws.gov/ecp/species/3651#rangeInfo>.
data_units Categorical classified into one of the following habitat suitability categories: 0: Not suitable. 1: Moderate foraging. 2: High foraging. 12: High reproduction, Moderate foraging. 21: Moderate reproduction, High foraging. 22: High reproduction and foraging.
