The document discusses the importance of maintaining and restoring wildlife connectivity in the Bay Area, emphasizing that roads and human impacts isolate natural areas, hindering animal movement. It highlights a study that identified 66 focal species and conducted a least-cost corridor analysis to define areas for improved wildlife travel between protected areas. Key findings include potential habitat links for species such as the mountain lion and proposed retrofitting designs for improved wildlife crossings.
2013 Open Space Conference - Linkages Panel

Editor's Notes
- #10: 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.
