NatureServe Conservation Status
Rounded Global Status Rank: G1 - Critically Imperiled
Reasons: Known from fewer than 10, relatively isolated populations, all located in the Santa Cruz Mountains of California. There are about 5,100 individuals occupying a total of about 142 ha. There are no imminent threats from habitat alteration or destruction, but the species is somewhat threatened by disruption of natural fire cycles, introgression with other species of cypress, and the potential for oil and gas drilling.
