Geographic Range [top]

Range Description: This species is known from two areas in Fresno County, California: the vicinity of the type locality in the lower drainage of the Kings River system, on the western slope of the Sierra Nevada, at an elevation of 335-340m asl (Jockusch, Wake and Yanev 1998); and Summit Meadow, at an elevation of 2,470m asl, in Kings Canyon National Park and about 37 kilometers east-south-east of the lower elevation sites (Stebbins 2003). Additional populations might occur in between known sites. Salamanders discovered in the Middle Fork Kaweah River drainage (610m asl, Sequoia National Park) have been referred to this species (Jockusch and Wake 2002).

Population [top]

Population: The small cluster of sites at lower elevations appear to be stable; salamanders have been found here intermittently for the last 25 years. A total of seven specimens have been found at the single high-elevation site on two occasions over a 45-year period (Hansen and Wake 2005).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: It is known from a well-shaded, north-facing slope in an area of mixed chaparral with Aesculus, Umbellularia, and Quercus wislizenii and scattered Pinus sabiniana, P. ponderosa, and Q. douglasii; found under rocks in areas of talus near the roadside (Jockusch, Wake and Yanev 1998).
Systems: Terrestrial

Threats [top]

Major Threat(s): Threats are unknown. Its habitat does not appear to be threatened, although the lower Kings River sites are located immediately adjacent to a road and probably would be affected by road construction.

Conservation Actions [top]

Conservation Actions: All known localities where this species has been recorded are on public lands administered by the USDA Forest Service or National Park Service (specifically, Kings Canyon National Park).
