Geographic Range [top]

Range Description:	This species occurs on the western slope of the southern Sierra Nevada, California, USA. It is found from the lower Kern River canyon in Kern County to highlands drained by Tule River and Kern River in central Tulare County, and from one site on the western margin of the Kern plateau (east of Kern River; Jockusch et al. 1998). The type locality is at 730m asl, and other populations in the lower Kern Canyon have previously been found as low as 500m asl. Outside the canyon populations occur at substantially higher altitudes (1,200-2,500m asl; Jockusch et al. 1998). Its distribution is probably poorly known.

Population [top]

Population:	Total adult population size is unknown but probably is at least a few thousand.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	At higher altitudes, this species occurs mainly in heavily forested areas in mixed pine-fir-incense cedar forest, sometimes with substantial numbers of deciduous oaks. In lower Kern Canyon, the tree cover is sparse and consists mainly of deciduous and live oaks with scattered pines and buckeyes and a few sycamores in the bottoms of the creeks (Jockusch et al. 1998). This species is often found under logs and rocks at the edge of springs and seepages, and is sometimes in the film of water, although on other occasions it can be found at some distance from water. It breeds on land, and eggs of this species have been found under objects along the banks of a shallow stream (Stebbins 1972).
Systems:	Terrestrial; Freshwater
