WILDLIFE SPECIES: Perognathus parvus | Great Basin Pocket Mouse
GENERAL DISTRIBUTION : The Great Basin pocket mouse occurs in the Columbia River and Great basins and adjacent lands. It is distributed from south-central British Columbia and eastern Washington south to southeastern California, Nevada, and northern Arizona and east to southeastern Montana and Wyoming [3,43]. Distribution of subspecies is [18,21]: Perognathus parvus bullatus: central and east-central Utah P. p. clarus: extreme southwestern Montana; southeastern Idaho; extreme north-central Utah; extreme southwestern Wyoming P. p. columbianus: central and southern Washington P. p. idahoensis: south-central Idaho P. p. laingi: south-central British Columbia P. p. lordi: extreme south-central Bristish Columbia; central and eastern Washington; northwestern Idaho P. p. mollipilosus: south-central Oregon; north-central and northeastern California P. p. olivaceus: most of Nevada; eastern California; extreme southeastern Oregon; southern Idaho; western Colorado; most widely distributed subspecies P. p. parvus: southeastern Washington; central and eastern Oregon P. p. trumbullensis: southern Colorado; northern Arizona P. p. yakimensis: south-central Washington The yellow-eared pocket mouse occurs on the eastern slope of the Tehachipi Mountains in Kern County, California [21,43]. It is not certain whether its distribution is disjunct or joins that of P. parvus olivaceus [18].

It most commonly occurs in sagebrush (Artemisia spp.), shadscale (Atriplex confertifolia), and other desert shrub, and in pinyon-juniper (Pinus-Juniperus spp.) woodland. On the eastern slope of the Cascade Range and the Sierra Nevada, it occurs in ponderosa pine (P. ponderosa) and Jeffrey pine (P. jefferyi) woodlands [18]. Riparian zones may have larger concentrations of Great Basin pocket mice than upland areas [8,9]. REFERENCES : NO-ENTRY
