H-26 Rabbits and Hares Rabbit and bare species encountered on the site during the 1980-1982 study included Nuttall's cottontail, desert cottontail, black-tailed jackrabbit, and the white-tailed jackrabbit. During this period, a total of 37 individuals were observed. Cottontails were the most canmonly observed species on the site--81 percent of the total obser- vations. Information obtained for the Piceance Basin region likewise indicates that cottontails are also the primary small game mammal in the Basin. Cottontails inhabit all vegetation types, with the highest populations occuring in the greasewood-sagebrush draws (BLM 1984b). Idhite-tailed and black tailed jackrabbits were less frequently observed and accounted for ]6 and 3 percent of the observations, respectively (LGL 1981). H.3.4 Reptiles and Amphibians • During the 1980 and 1981 studies, one species of frog, three species of lizard, and two species of snake were observed in the sodium lease area. Species observed included the chorus frog, short-horned lizard, sagebrush lizard, eastern fence lizard, gopher snake, and the western terrestrial garter snake. In terms of habitat affinity, the chorus frogs were heard in the vicinity of Yellow Creek in the wet area. The short-horned lizard and sagebrush lizards were observed in all habitat types except in the greasewood-sagebrush bottom habitats. The western terrestrial garter snake was observed in the bald habitat.
