Predicted Distribution
Reptiles do not migrate as some birds and mammals, so the colored areas depict the predicted range for the Side-blotched Lizard year-round. The habitats were identified using 1991 satellite imagery, other datasets and experts throughout the state, as part of the Washington Gap Analysis Project.

Distribution and Habitat Requirements
Uta stansburiana reaches its northern limit in the warmest part of the Columbia Basin in Washington State. This species may be found on sand, rocky soil, desert pavement and boulder slopes and is abundant on vertical cliff faces of some of the rocky desert canyons. It prefers open areas with few or no trees. In a study on the Hanford Reservation's Rattlesnake Hills, vegetation within the lizard's range included Artemisia tridentata (big sagebrush), Poa secunda (Sandberg bluegrass), Agropyron spicatum (Bluebunch Wheatgrass) and Bromus tectorum (Cheatgrass).

The Central Arid Steppe zone was considered core in the Columbia Basin ecoregion. Good habitats were cliffs, talus slopes, grasslands, shrub savannas and shrublands.
