Range Extent20,000-200,000 square km (about 8000-80,000 square miles)
Number of Occurrences81 - 300
Rank Reasons
Small range in southern California, but many stable populations likely exist throughout the historical range.
Range Extent Comments
Santa Cruz Island and southern coastal mountains of California, from around San Simeon in Monterey County southward to the Palos Verdes Hills and Santa Ana Mountains (Petranka 1998); Sierra Nevada populations formerly included in this species are now assigned to B. GREGARIUS (Stebbins 1985, Jockusch et al. 1998).
Occurrences Comments
Represented by many and or large occurrences throughout the range.
Threat Impact Comments
Presumably ongoing urbanization is the greatest threat.
