Fifty-four mammal species were identified in the park, of these 19 species are year-round residents that are also considered common or abundant. Large mammals that are considered seasonally common to year-round residents include the Roosevelt elk (Cervus canadensis rooseveltii), black-tailed deer (Odocoileus hemionus columbianus), mule deer (Odocoileus hemionus), and black bear (Ursus americanus). Common small mammals and year-round residents that may be expected to occur along the Highway 62 West corridor include the golden-mantled ground squirrel (Spermophilus lateralis), Townsend chipmunk (Tamias townsendii), yellow pine chipmunk (Tamias amoenus), Douglas squirrel (Tamiasciurus douglassii), northern flying squirrel (Glaucomys sabrinus), Sierra pocket gopher (Thomomys talpoides), and deer mouse (Peromyscus maniculatus).

Amphibians, Reptiles, and Fish

Amphibian species that are common within the park and could occur within the Highway 62 West corridor include the long-toed salamander (Ambystoma macrodactylum), boreal toad (Bufo boreas boreas), and Pacific treefrog (Hyla regilla) (NPS, Crater Lake National Park 2002a). Reptile species are unlikely to be present within this corridor due to elevation and minimal habitat. Four species of trout, e.g., bull (Salvelinus confluentus), eastern brook (S. fontinalis), rainbow (Oncorhynchus mykiss), German brown (Salmo trutta), and the kokanee salmon (O. nerka) are present within waters of the park; however, no fishery habitat occurs within the Highway 62 West corridor.
