Range Description

The geographic range extends from southeastern Arizona (Chiricahua, Dragoon, Whetstone, Huachuca, and Santa Rita mountains) and extreme southwestern New Mexico (Animas Mountains) in the US, into Mexico south through the Sierra Madre Occidental and Sierra del Nido of eastern Sonora and western Chihuahua into northwestern Durango (Lowe 1964, Degenhardt et al. 1996, Stebbins 2003). This is primarily a montane species, but it occurs or occurred on high grassy plains of Animas Valley (New Mexico), Sonoita Plain (Arizona), and near Yepomera (Chihuahua), as well as in mountains (Smith et al. 1996, Watkins-Colwell et al. 2003). The elevational range extends to at least 3,350 m (around 11,000 feet); some isolated populations occur at elevations as low as 1,220 m (about 4,000 feet) (Bock et al. 1990); typically between 1,500 to 3,000 m (Degenhardt et al. 1996).
