The influence of forest understory characteristics on snowshoe hare (Lepus americanus) habitat use and density was studied in eastern (Cherryfield) and western (Pierce Pond) Maine during 1981-83. Fecal pellet counts indicated that hares at Cherryfield preferred hardwood and avoided mixedwood and open understories during the leaf-off season (Oct-May) (P < 0.05). At Pierce Pond, hares used softwood more and hardwood and open understories less than expected during leaf off (P < 0.05). Hardwood understories provided the densest cover at Cherryfield, whereas at Pierce Pond softwoods were the densest cover. Hares in both areas used dense understories less during the leaf-on season (Jun-Sep). Spring population densities (0.1-1.7/ha) were correlated with understory density (r = 0.94, P < 0.001). Overwinter survival also was associated with understory density (r = 0.74, P < 0.04). Dense understories provided escape and thermal cover.
