|Scientific Name:||Batrachoseps simatus Brame & Murray, 1968|
|Red List Category & Criteria:||Vulnerable D2 ver 3.1|
|Reviewer(s):||Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)|
Listed as Vulnerable because it is known from fewer than five locations.
|Previously published Red List assessments:|
|Range Description:||This species is known from a number of sites in the lower Kern River Canyon, Kern County, California, at the southern end of the Sierra Nevada mountain range in the USA. It occurs in isolated colonies, and probably occurs in many densely wooded canyons in the lower Kern River Canyon. They have been recorded from 450-1,220m asl. Populations in the vicinity of Fairview, Tulare County, have been allied with B. simatus, but probably represent a distinct species.|

|Population:||Total adult population size is unknown, although individual population sizes are presumably quite small. It is locally abundant (Bury, Dodd and Fellers, 1980).|
|Current Population Trend:||Stable|
|Habitat and Ecology:||It favours north-facing slopes and small wooded tributary canyons. It also inhabits oak-pine communities on slopes; willow and cottonwood communities along streams; chaparral; and may range into grassland adjacent to woods. It is often found in crevices in talus slopes or under rocks and logs. It is a terrestrial breeder.|
|Major Threat(s):||At present there do not appear to be any significant threats. Potential future threats include cattle grazing, highway construction, and the proposed development of water storage facilities within the Kern River Canyon.|
|Conservation Actions:||Nearly all the known populations occur on public lands administered by the Sequoia National Forest. Kern Canyon slender salamanders are listed as Threatened by the State of California and are a Federal Species of Concern.|
