Cupressaceae

Cupressus arizonica var. glabra (Sudw.) Little

Locally abundant but restricted to a few counties in Arizona, U.S.A. and has a small extent of occupancy and could become threatened if fires became more destructive in future.

Distribution

This variety is found in the USA: Arizona (Coconino, Gila, Maricopa and Yavapai Co.). It appears to be locally common with a stable population.

Habitat and Ecology

In Pinyon-Juniper woodland with Pinus edulis, P. ponderosa, Juniperus deppeana, J. scopulorum, J. osteosperma; common in ravines or canyons among sandstone, slate or granite rock or on rocky slopes.

Human Uses

This is commonly the form used in cultivation.

Conservation Status

Global Status

Near Threatened

Global Rationale

Despite the abundance of individuals and no evidence of decline, this variety has a small extent of occurrence well within the threshold for Endangered; its area of occupancy and number of locations also fall within these limits. It could become threatened if fires became more destructive in future, so Near Threatened seems to be an appropriate category (almost qualifies for listing under criteria B1ab(iii)+2ab(iii)).

Conservation Actions

Proper fire management, allowing fires to set off regeneration but not to destroy subpopulations, is the most important issue.
