Populations of reptiles were examined in grazed and ungrazed habitats dominated by sagebrush (Artemisia tridentata) or by crested wheatgrass (Agropyron cirstatum) on the Idaho National Engineering Laboratory (INEL) Site in southeastern Idaho. The sagebrush lizard (Sceloporus graciosus) and the short-horned lizard (Phrynosoma douglassi) were the only species of reptiles encountered in sufficient numbers to permit statistical analysis. Both of these species preferred sagebrush habitats to areas dominated by crested wheatgrass. The sagebrush lizard was most abundant in the native, ungrazed, sagebrush habitat, and the short-horned lizard was most plentiful in the sheep-grazed area dominated by big sagebrush.
