|Scientific Name:||Batrachoseps robustus Wake, Yanev and Hansen, 2002|
|Red List Category & Criteria:||Near Threatened ver 3.1|
|Reviewer(s):||Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)|
Listed as Near Threatened because although the species appears not to be in decline, its Extent of Occurrence is less than 5,000 km2, thus making the species close to qualifying for Vulnerable.
|Range Description:||This species is known from about three dozen sites from 1,615-2,800m asl in the southern Sierra Nevada, California, USA: in Kern Plateau, Tulare County, the western margin of the Owens Valley, Inyo County, and the Scodie Mountains, Kern County (Wake, Yanev and Hansen 2002).|

|Population:||The total adult population size is unknown but is likely to be at least several thousand. Extensive fieldwork by Wake, Yanev and Hansen (2002) yielded more than 350 specimens. The habitat is of limited extent, especially the springs of the Kern Plateau and Scodie Mountains. Its population trend is unknown, but very likely to be relatively stable. Wake, Yanev and Hansen (2002) mentioned no evidence of any declines.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||It can be found along small permanent creeks and springs with riparian vegetation in arid wooded mountains, typically under stones and wood (Wake, Yanev and Hansen 2002). It breeds terrestrially by direct development.|
|Major Threat(s):||This species is vulnerable to habitat degradation through capping of springs by man, or other alterations of spring water habitat. Its habitat is easily altered by intrusion by man. Flash floods also pose a natural threat. These threats tend to be very localized, however, and overall this species is not significantly threatened under current conditions.|
|Conservation Actions:||The Kern Plateau and Scodie Mountain populations are on United States Department of Agriculture Forest Service land, but the level of protection might be inadequate.|
