Threat ImpactLow
Range Extent100-250 square km (about 40-100 square miles)
Number of Occurrences6 - 20
Rank Reasons
Small range in the Kern River drainage in southern California; some populations are vulnerable to habitat degradation from human activities; relatively common and not known to be declining.
Range Extent Comments
This species known only from the Upper Kern River Canyon, and along the west side of the current Lake Isabella; the southern limit of its distribution is near the original junction of the main and South forks of the Kern River (Jockusch et al. 2012). The southernmost known locations are from Wofford Heights on the west side of the river and about 2 kilometers south of the Cannell Creek drainage on the east side of the river (Jockusch et al. 2012). The range extends north at least as far as 1 kilometer north of the confluence of South Falls Creek with the Kern River (Jockusch et al. 2012). Areas farther north have not been thoroughly surveyed, and it is likely that the range extends farther north in the Upper Kern River Canyon (Jockusch et al. 2012). Known elevational range is 860-1,280 meters, one of the most restricted among all species of Batrachoseps (Jockusch et al. 2012).

Known populations range for about 30 kilometers from south to north (Jockusch et al. 2012).
Occurrences Comments
This species is represented by a moderate number of occurrences (subpopulations) and locations (as defined by IUCN). On a somewhat coarse scale, Jockusch et al. (2012) mapped approximately 20 collection sites, but not all of these necessarily represent distinct occurrences.
Threat Impact Comments
Primary threat is habitat alteration and disturbance such as may result from the use of heavy equipment for fire suppression or road maintenance (Jockusch et al. 2012).
Ecology & Habitat

Habitat

On the east side of the Kern River, the range of this species lies entirely within a prominent uplifted ridge of metrocks paralleling the river, on north-facing slopes and talus vegetated with chaparral as well as Pinus sabiniana and occasionally Quercus chrysolepis (Jockusch et al. 2012). Most individuals have been found beneath rocks, often on or at the base of talus slopes, but some have been found in a variety of other habitats and under a variety of cover objects, including under a log in an open sandy flood plain, under logs and rocks in grasslands, in gravel on the river bank, and in leaf litter in protected groves (Jockusch et al. 2012).
