<br />r , <br />L_J <br />3.0 DESCRIPTION OF ESISTING ENVIRONtfENT <br />3.1 Mammals <br />3.1.1 Small Mammals <br />A list of mammal species trapped, observed, and recorded by sign or <br />s <br />local record, as well as mammals which may be present based on species <br />distribution and knowledge of habitat preference, is presented in <br />Table 3.1.1-1. The only species of small mammals trapped during the <br />small mammal sampling period were deer mice (Peromyscus maniculatus) <br />and least chipmunks (Eutamias minimus). Results of this trapping effort <br />are presented in Table 3.1.1-Z. Other small mammal species observed or <br />deemed to exist on site due to sign are: Richardson's ground squirrel <br />(Spermophilus richardsonii), golden-mantled ground squirrel (Spermo- <br />hilus late~alis), red squirrel (Tamiasciurus hudsonicus), Northern <br />pocket gopher (Thomomys talpoides), bushy-tailed woodrat (Neotoma cinerea), <br />long-tailed vole (Microtus lonRicaudus), and muskrat (Ondatra zibethicus). <br />Additional small mammal species were identified in the area by Dames and <br />Moore (1975). These included: Colorado chipmunk (Eutamias quadrivitta- <br />tus), white-tailed prairie dog (C nom s leucurus), southern red-backed <br />vole (Clethrionomys gapperi), montane vole (Microtus montanus), and <br />western jumping mouse (Zapus princeps). <br />The ubiquitous deer mouse was found over the entire study area. It <br />• <br />was most prevalent in the mountain shrub habitat and least abundant in <br />the wet meadow. Least chipmunk was found most frequently in the moun- <br />tain shrub and were not trapped in either the wet meadow or sagebrush <br />habitat. Richardson's ground squirrels were most abundant in wet meadow <br />
