California Vole
(Microtus californicus)

The California Vole is a gray-brown, medium sized mouse that occurs sporadically on the Etiwanda Fan. This is the only Microtus species that occurs on the Etiwanda Fan. The California Vole is thought to occur in wetlands, meadows and other moist habitats but these small mammals have been captured frequently in semi-arid habitats including coastal sage scrub and alluvial fan sage scrub. The California Vole is found throughout all but the most arid regions of California and south into Baja California. There are 17 races of California Vole. The local race is M. c. sanctidiegi.
