Microtus pinetorum 


Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Mammalia Rodentia Cricetidae

Scientific Name: Microtus pinetorum
Species Authority: (Le Conte, 1830)
Common Name(s):
English Woodland Vole
Taxonomic Notes: Van der Meulen (1978) regarded subspecies nemoralis and parvulus as species distinct from pinetorum, as have some other authors, whereas Whitaker and Hamilton (1998) regarded all as inseparable. Musser and Carleton (in Wilson and Reeder 1993, 2005) indicated that further study is warranted and included them as subspecies as is also done here.

Population [top]

Population: Woodland voles tend to be sparsely distributed in natural habitats, densities usually are highest in orchards during fall. The average population density is up to 2.4 per hectare (Miller and Getz 1969). Recorded densities range up to 15 per hectare, although they likely reach higher numbers in orchards. There is a rapid turnover of individuals in a population.
Current Population Trend: Stable
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: It lives in a wide variety of habitats, but in many areas prefers upland wooded areas with a thick layer of loose soil and humus. It spends most of its time underground in shallow burrow systems. Young are born in nests built beneath logs, below surface litter, or underground. Woodland voles breed mid-February to mid-November, probably year-round. In Oklahoma: apparently all year, with the peak October-May; 1-4 litters per year; litter size is 1-5 (average 2.6) (Caire et al. 1989).

Home range is estimated at about 0.1 hectares. These voles are not territorial, they appear to occur only in loose social groups. Diet includes roots, bulbs, seeds, fruits, and other vegetable matter. Active throughout the day, year-round. Sometimes regarded as a pest; can do serious damage to nurseries and orchards. May damage apple trees by removing bark from roots, especially in winter.
Systems: Terrestrial
