Habitat and Ecology [top]

Habitat and Ecology: It inhabits agricultural land, coastal dunes, grassy meadows, coniferous and deciduous forest and woodland, along streams. It is fossorial, and occasionally active on the surface (especially dispersing juveniles in summer). It quickly recolonizes formerly flooded areas. Breeding nests are located about 15 cm below the surface of the ground. The nest cavity is lined with coarse grass. It is about 20 cm across and has several entrances (van Zyll de Jong 1983). This species is solitary except when breeding. It breeds January to early March. Parturition occurs in late March or early April. The litter size is two to four, with one litter annually. Females are reproductively active at 9-10 months. The maximum longevity probably is about four to five years. The diet is dominated by earthworms; other common food items include adult and larval insects, and other invertebrates. It is active throughout the year. The average home range has been estimated at 0.12 ha.
Systems: Terrestrial

Threats [top]

Major Threat(s): There are no major threats to this species.

Conservation Actions [top]

Conservation Actions: This species is not of conservation concern. However, an inventory of populations east of the Cascade Range in Washington and Oregon would clarify the status in that region (Verts and Carraway 1998).
