Of conservation concern.
Arctostaphylos hooveri is known from the northern Santa Lucia Mountains in Monterey County. Populations are associated with openings in yellow pine forests and patches of chaparral.

Subspecies 6 (6 in the flora).
Arctostaphylos crustacea comprises populations from central California and the Channel Islands in areas moderated by summer maritime fog. One subspecies is widespread, from the San Francisco Bay area to the Channel Islands; the others are limited in distribution.
