A Guide to the Amphibians and Reptiles of California
These maps illustrate the general historic range of established native and non-native snakes found in California.
Red, or another color indicated below the map, shows this distribution. Snakes of the species or subspecies shown are expected to be found within the illustrated area in places where suitable habitat and conditions occur. In some cases, the current range may be fragmented or considerably diminished from the range illustrated here.
