Discussion
Bergerocactus emoryi is exceedingly rare in California, because its habitats have been heavily disturbed or eliminated. It survives mostly within nature reserves in several coastal mainland localities and on Santa Catalina and San Clemente islands, California. The species is fairly common (and more variable) along the Pacific slope of Baja California, Mexico, and its offshore islands south to 29º 48´ N. In Mexico, B. emoryi inhabits sandy, rugged, steep coastal bluffs and nearby coastal scrubland hillsides, located within the coastal fog zone.
