Conservation Status: Least Concern.


Keen's Deermouse is the most common deermouse in the Pacific Northwest. It inhabits rainy, mild climate zones at higher elevations than the closely-related North American Deermouse (Peromyscus maniculatus), and prefers areas where the forest canopy is somewhat open. Observers report that it is very good at climbing and jumping. It is often a pest in rural areas, especially in winter, because it readily moves into buildings.
