Fisher Reproductive Habitat Suitability (polygon format), Southern Sierra Nevada

Note: Model outputs were clipped to remove extrapolation areas considered less reliable north of the Tuolomne River/Tioga Road and southeast of the Kern River and Kings Canyon National Park.

PLEASE READ:
The fisher reproductive habitat model and maps presented here provide an approximate, landscape-scale representation of those areas of the southern Sierra Nevada considered most likely to support fisher mothers and young during that sensitive portion of the reproductive cycle when kits remain with, and are likely dependent on, their mothers. Maps depicting the distribution of modeled moderate and high-value reproductive habitat are meant to focus management attention, not to prescribe specific management actions or specific management areas. Female fishers are known to establish dens and reproduce outside of modeled moderate-high value areas, and these maps should not be used to conclude absence of reproductive habitat, dens, or fishers outside of thresholded High and Moderate habitats. We recommend managers use the thresholded version (High and Moderate reproductive habitat value) for project planning purposes, in concert with additional, local or fine-scale information where available, and field reconnaissance where possible.
