Our single specimen was taken on a creosote-dominated alluvial slope, where Dipodomys merriami and Peromyscus maniculatus were common, 3.3 mi.
Stands of creosote (Larrea tridentata) occupy the surrounding plain and alluvial slopes. Floors of canyons support a variety of annual vegetation, cacti (Opuntia sp.) and such woody plants as mormon tea or ephydra (Ephydra sp.), mesquite (Prosopis glandulosa), and allthorn (Koeberlinia spinosa).
-- The deer mouse seems quite localized in distribution; our four specimens were taken only on alluvial slopes covered by creosote, 3.3 mi.
