1. Maintaining and
restoring critical wildlife
linkages in the Bay
Area
The Bay Area Open Space Council conference on “Collective Impact.”
May 16, 2013
8. Least-Cost Corridor Analysis
Goal: Define area with lowest relative cost of travel for focal
species between protected core areas
Walker and Craighead 1997
Craighead et al. 2001
Singleton et al. 2002
So we replicated this process throughout the 14 linkage planning areas. This map shows the overlap of the species least cost corridors. We conducted landscape permeability analyses for 11 of the 66 selected focal species, including mountain lion, bobcat, American badger, San Joaquin kit fox, ringtail, black bear, black-tailed deer, Tule elk, western gray squirrel, wrentit, and California quail. The number of species this analysis was conducted for ranged from three to nine species across the priority linkages.
