WILDLIFE DISTRIBUTION AND OCCURRENCE
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].

PLANT COMMUNITIES : 
The Great Basin pocket mouse occupies steppes and open, arid shrublands
and woodlands.  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].
