Taxonomic Comments
Based on biochemical data, populations scattered through the Tehachapi Mountains to Fort Tejon, Kern County, tentatively were assigned to this species by Stebbins (1985).

Threat ImpactMedium
Range Extent1000-5000 square km (about 400-2000 square miles)
Number of Occurrences6 - 20
Rank Reasons
Spotty distribution in a small area of southern California; less than 20 known occurrences; some threats to populations, mainly habitat destruction.
Range Extent Comments
This species is known from scattered sites in the Caliente Creek drainage, Piute Mountains, southern Sierra Nevada, Kern County, California; scattered populations in the Tehachapi Mountains to Fort Tejon, Kern County, California, tentatively have been assigned to this species on a biochemical basis; elevational range 2000-4600 ft (610-1400 m) (Stebbins 1985). Distribution is probably spotty but somewhat continuous in good habitat.

An historical report of B. stebbinsi (Richman 1973) actually pertains to B. robustus.
Occurrences Comments
There are eight localities over an area of about 50 by 30 miles. All populations are believed to be extant.
Threat Impact Comments
Major threat is of development of Tejon Ranch for housing; may not do very well in developed areas. Logging may cause extirpation of populations. Flood control in Caliente Creek Canyon could adversely impact habitat (California Department of Fish and Game 1990). Detrimental activities include wood cutting or gathering, road building, and other activities involving land clearing (Biosystems Analysis 1989).
Ecology & Habitat

Description

A large Batrachoseps with long legs and large feet.

Habitat

Moist talus slopes and canyons; oak and mixed pine-oak woodlands; typically under rocks and decomposing logs in dense leaf litter. Usually on north-facing slopes (California Department of Fish and Game 1990). Blue oak savanna, digger pine-oak woodlands, mixed conifer forest, and deciduous riparian areas (Biosystems Analysis 1989). Terrestrial breeder.

Reproduction

Little information available. Apparently clutches number about 10-20 eggs. There is probably only 1 clutch per year. Terrestrial breeder, no aquatic larval stage.
