Distribution and Habitat Requirements
Phrynosoma douglasii commonly occurs throughout the Columbia Basin and the Cascades foothills in a variety of habitats including sagebrush plains, short-grass prairies and occasionally in open pine forests. Always found near patches of loose soil or sand for burrowing. The substrate (soil layer) is always well-drained. However, this species is uncommon in steppe and inter-mountain forest. This species is found near ant hills.
The Columbia Basin, Okanogan Highlands and Northeast Corner ecoregions were selected. All of the steppe zones within its range were core, except for the Klickitat Meadow Steppe and Palouse (the dampest steppe zones). Ponderosa Pine, Klickitat Meadow Steppe and Palouse zones were marginal. Grasslands, shrub savannas, shrublands and tree savannas were good habitats.
