Description

Habitat

Typically found at an altitude of 0 to 1,677 meters (0 to 5,502 feet).[1]

Ecology: It is found in the moist forests of the Pacific coast, brushy, grassy areas. It is most abundant in more xeric sites, especially those supporting stands of short grass , but may favour riparian areas in some localities. More abundant in clearcuts than in virgin forest. It occupies shallow burrows and low cover .

Young are born in nests , dry grasses are placed in cavities under logs or in similar protected sites. Breeding occurs mainly from March to September in Oregon and British Columbia. Gestation is approximately 23 days. Females are estimated to produce a maximum of four or five litters per year, with approximately three to four young per litter.

Diet consists primarily of green vegetation (presumably both forbs and grasses); they also eat fungi. Although active at any time, this species is most active at night.[2].
