Southernmost coastal fisher since Joseph Grinnell

Fishers (Pekania pennanti) are a forest-specialist mesocarnivore and are a species of special concern in California (CDFW 2015a, 2015b). In comparison to the Sierra and Cascade populations, the coastal population is under-studied and the southern extent of its range is not clearly documented (Zielinski et al.
1995).

We documented a fisher at the southern edge of Lake County. This is the southernmost documented fisher sighting since Joseph Grinnell. Grinnell, in his review of fisher locations in 1937, noted that fishers may extend as far south as Marin County, but had no definitive proof.

The full documentation of this sighting is available at http://publish.illinois.edu/maxallen/files/2019/01/Allen-2015-Fisher-Range-Expansion.pdf
