Breeding Range Map
The Deer Mouse occurs in almost all habitats in the state. In the western part of the state, it does best in dry, open forest in the Puget Trough. It is the only deer mouse on the islands of Puget Sound. It becomes less common the wetter and more closed the canopy of the environment. It can be found from sea level to as high as 7000 feet on Mount Adams.
Core areas in all zones east of the Cascade crest except Interior Western Hemlock. West of the crest, core in Puget Sound Douglas-fir, the Cowlitz River, and Willamette Valley zones. In core zones, all habitats were good except high-density development and bare ground.
