Distribution and Habitat
Distribution is restricted to the Central Valley of California and lower elevations to the west. The range includes areas around Sonoma, Petaluma, and the Colusa-Yolo county line, south to the vernal pools in Tulare County, and amongst the coast ranges south to the ponds and vernal pools in the Santa Ynez Drainage (Santa Barbara County).
The habitat of this salamander is restricted to grassland and low foothills, where the long-lasting vernal pools it uses for breeding exist. Permanent aquatic sites can be used for breeding, but use of such sites is only common in the absence of predatory fish. Dry season habitat sites are within reasonable distance of breeding sites, and generally consist of small mammal burrows as well as man-made enclosures.
