Population [top]

Population:This species is represented by many occurrences or subpopulations. Price (1991) mapped roughly 50 collection sites. These snakes are secretive but not uncommon in the Chiricahuhua Mountains in Arizona (Degenhardt et al. 1996). Extent of occurrence, area of occupancy, number of subpopulations, and population size are probably relatively stable.
Current Population Trend:Stable
Additional data:
Number of mature individuals:10000
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Habitats include woodlands and chaparral of rocky mountain canyons near streams in the United States, montane mesophytic forests along the slopes of the Mexican highlands and in Central America, and xeric forest in western and southern Mexico (Price 1991, Stebbins 2003). Sometimes this snake can be found in agricultural areas or in buildings in towns. It is terrestrial and arboreal and uses rock crevices or underground burrows as shelter. This is an egg-laying species.
Movement patterns:Not a Migrant
