Dr. Sacks discusses research on Sierra Nevada red fox and the Sacramento Valley red fox. Historically, Sierra Nevada red fox were present throughout the subalpine zone of the Sierra Nevada range in California but over the last century, their abundance and distribution have declined dramatically. The Sacramento Valley red fox was recently shown to be a second native subspecies confined to the northern Central Valley. Dr. Sacks presents findings on biogeography, ecology, and conservation issues in the context of previous and ongoing research. Video: Sierra Nevada and Sacramento Valley red fox.
