Juvenile California tiger salamanders are a dark olive green color, and as they mature, their skin becomes black with white or yellow spots. The California tiger salamander can be found in the Central Valley of California and its bordering foothills, coastal grasslands and seasonal wetlands. THREATS The primary cause of the decline of California tiger salamander populations is the loss and fragmentation of habitat from human activities and the encroachment of nonnative predators. Endangered species are plants and animals that are in immediate danger of becoming extinct. The California tiger salamander (Ambystoma californiense) (listed at Vulnerable), the barred tiger salamander (A. mavortium), and the plateau tiger salamander (A. velasci) were all once considered subspecies of A. tigrinum, but are now considered separate species. Tiger Salamanders live in the edges of mixed woodland and coniferous forest, grasslands and low foothills with long-lasting spring and summer rain pools for breeding. Sonoma County is home to the California Tiger Salamander (CTS) and several protected plant species (listed plants). More recently, genetic comparisons indicate that the California Tiger Salamander is a genetically distinct species that is endemic to the state (Larson 1996, Shaffer 1994). Endangered Species Protection Program (ESPP) The California tiger salamander is both an endangered species and a threatened species. The California tiger salamander mates near ponds and seasonal pools where it lays its eggs underwater. Where Do California Tiger Salamanders Live? Originally, biologists recognized the California Tiger Salamander as a subspecies of the geographically widespread tiger salamander (Ambystoma tigrinum). Its numbers have dropped due to habitat loss, predation from crayfish and bullfrogs, being hit by cars during migration and interbreeding with the non-native tiger salamanders. Newly hatched larva take 3 to 6 months to reach the juvenile stage when they are able to move onto land. California tiger salamander population by distance, mountains and major waterway barriers for more than 700,000 years. Though we are happy to host and conserve lands for endangered species, this can provide some challanges to land development in CTS breeding zones and around adult CTS occurances. Animex California Tiger Salamander (Ambystoma californiense) fencing. Keep Salamanders out of construction zones. Their range extends in California, throughout the Sacramento and San Joaquin River valleys, in the surrounding foothills, and lower elevations by the central coast.
