The complete county distribution, spread across 57 California counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Gray fox reports favor California landscapes with cover, including chaparral, oak woodland, forest edges, and brushy canyon bottoms. Records stretch from coastal ranges into Sierra foothills and southern hills, showing a broader setting than the state’s open deserts or farm fields alone.

Observations occur through every month without one narrow seasonal spike. Changes in night length, road travel, and trail-camera effort can shift the totals, so the curve isn’t evidence of population growth or decline.

Roads and settled edges make a mostly nocturnal fox easier to document, while private ranches and thick backcountry stay less evenly watched. California’s freeways can also split wooded routes, but report clusters don’t reveal how many foxes remain on either side.
