Rounded Global Status Rank: G2 - Imperiled

Reasons: Dudleya blochmaniae is known from about twenty-four extant occurrences in California and fewer than five occurrences in Baja California, Mexico. The taxon is seriously threatened by development, urbanization, vehicles, foot traffic, exotic plant invasion, cattle tramping, grazing by feral herbivores, horticultural collecting, and fire break construction.
