Voles construct an extensive system of underground tunnels with numerous burrow entrances. A single burrow system may contain several adults and young. Voles may breed throughout the year, but the most common time is spring and summer. The gestation period is about 21 days, the young are weaned within 21 days, and the females mature in 35-40 days. Lifespans are short, probably ranging from 2-16 months.
Many voles are excellent swimmers.
The pine vole is a bit clumsy in his climbing ability. Voles are prey for many predators, including coyotes, snakes, hawks, owls, and weasels, however predators do not generally control vole populations. Damage and Damage Identification Voles may cause extensive damage to orchards and forests due to the girdling of seedling and mature trees. Girdling damage may also occur to ornamental plants. Girdling damage is most likely to occur in fall and winter.
