Characteristics of Habitat

Range and Population:

This species occurs through most of the United States, and ranges into southern Canada and northern and eastern Mexico, discontinuously southwards to Guatemala and Belize. It extends from southern British Columbia, southern Saskatchewan, Wisconsin, Michigan, southern Ontario, New York, and southern Maine southward in the United States to southern California, Arizona, New Mexico, Texas, the Gulf Coast, and southern Florida, and southward through northeastern, central, and southern Mexico to Guatemala and Belize (Wilson 1978, Lee 2000, Ernst and Ernst 2003, Stebbins 2003). Elevational range extends from sea level to about 2,550 m (8,300 feet). A record for Durango, Mexico, evidently is erroneous (Webb 2001).[1]
Countries:Native:
Belize; Canada; Guatemala; Mexico; United States

[1]
Population:This species is represented by a very large number of occurrences or subpopulations (at least several hundred). The total adult population size is unknown but probably exceeds 1,000,000. This snake is common in most of its very large range in the United States but appears to be rare at the southern extent of the range in southern Mexico, Guatemala, and Belize (Lee 2000). The extent of occurrence, area of occupancy, number of subpopulations, and population size are very large and probably relatively stable. Population Trend: Stable

Habitat and Ecology

[1][1]

Habitat Overview:

Most common in open areas such as fields, farms, and wetland margins.

Ecology Notes:

Habitats encompass a wide range of lowland and montane areas, including deserts, prairies, sandhills, shrublands, woodlands, forests, canyons, streamsides, and semi-agricultural areas. This snake is absent from the driest deserts and highest mountains (subalpine zones and higher). It commonly climbs shrubs and small trees. When inactive, it hides underground, in crevices, or under surface cover. Adults often hibernate communally, sometimes partly submerged in water. Eggs are laid in an underground tunnel or burrow, rotting stump, sawdust pile, or under a rock. Oviposition sites may be up to at least several hundred metres from the usual home range (Brown and Parker 1976; Iverson et al. 1995, Herpetological Review 26: 147-148).[1]
