From the IUCN Red List Species Account:


Range Description

This species is found throughout most of central and southwestern USA and portions of adjacent northern Mexico. It is absent from high mountains and the West Coast.

Habitat and Ecology

This species inhabits grasslands, deserts and semi-desert shrublands, river valleys and floodplains, agricultural areas, usually in areas with deep friable soils. It burrows underground or hides under rocks, plants, or other cover when inactive. Eggs and larvae develop in the shallow water of marshes, rain pools, ponds, lakes, reservoirs, flooded areas, and other bodies of water lacking a strong current.


Abundant and widespread. The population trend varies with location but is probably stable in most areas. See Sullivan and Lamb (1988) for evidence that B. woodhousii is displacing B. microscaphus in central Arizona.
