This species occurs in the Coast Ranges of California from Humboldt County, USA, to northwest Baja California Norte, Mexico. It also occurs in the central Sierra Nevada foothills; South Farallon, Santa Catalina, and Isla Coronado Norte (Behler and King 1979). It lives from sea level to about 1,500m asl (Stebbins 1985).
Habitat and Ecology
It inhabits coastal live-oak woodlands; yellow pine and black oak forests in the foothills. It is found on ground under leaf-litter, rocks, logs, etc.; it also climbs trees. It retreats to tree cavities, rodent burrows, caves, and mine shafts in summer. Lays eggs in hollow trees or logs and in cavities in the earth (Behler and King 1979). In Baja California it lives in sycamore woodland. It breeds by direct development, and is not dependent upon water.
It appears to have declined in some areas since the 1970s (D. B. Wake, cited by Petranka 1998), but remains common in many places.
It is a major threat is loss of large oaks and sycamores used for nesting and estivation.
The most important conservation need is protection of oak and sycamore woodland habitat and especially large old oak and sycamore trees. It occurs in several protected areas. This species is protected by Mexican law under the "Special Protection" category (Pr).
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
