Of conservation concern. Dudleya multicaulis is endemic to the Los Angeles coastal plain and adjacent hills, Transverse and Peninsular ranges, and southward to the San Onofre Mountains of northern San Diego County, an area now largely urban; it is considered fairly endangered (California Native Plant Society, http://cnps.web.aplus.net/cgi-bin/inv/inventory.cgi).
