Habitat
Northwestern deer mice are adapted to many habitats, but appear to thrive in upland and new-growth forests. They also commonly inhabit old-growth forests and floodplains, although those are less favorable because they lack the spatial and temporal complexity that promotes survivorship.

Food Habits
Northwestern deer mice are mainly granivorous ground foragers. In an intake preference study done on foods from southeastern Alaska seeds from trees, shrubs and fruits were compared as well as fruits for palatability. It was found that salmonberry, stink currants, devil's club seeds, and Sitka spruce seeds were preferred.
