land cover types. Moving westward, the species is associated more
with towns and cities and ponderosa pine forest. The logistic
regression analysis showed positive or negative association with mixed
conifer forest (Northeast Oregon), April precipitation (hex. min.), June
precipitation (hex. avg.), and-to a lesser degree-sagebrush steppe,
topographic variation, and July maximum temperature (hex. max.).
