Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-09-01

This species is listed as Least Concern in view of its wide distribution, presumed large population, tolerance of a broad range of habitats, and because it does not appear to be under threat and is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category. Subspecies sonoriensis and carminis have very restricted distributions and merit attention.

Habitat and Ecology [top]

Habitat and Ecology:Vegetational characteristics of habitats differ across the species' range, but almost always found near large rocks, boulders, or cliffs. Otherwise, habitats include montane forests of Ponderosa pine and spruce, juniper-pinyon pine woodlands, oak woodlands, saxicolus brush and pygmy-conifer woodlands, riparian vegetation, and desert shrublands.

In its northern range, this species is associated with pygmy conifer woodland, ponderosa pine woodland, saxicoline brush, maple associations, sagebrush and saltbush; in Arizona-New Mexico, with aspen, low elevation shrublands, deserts, and lava fields; various oak associations; in Durango, with madrone, manzanita, and other typical lower Sonoran riparian vegetation.

It is primarily terrestrial, but climbs rocks and sometimes woody plants. Dens and nests are in rock heaps, crevices, rocky bluffs and cliffs, underground burrows, and trees (Hart 1992).
Generation Length (years):3

Threats [top]
