Habitat
They are found in moist grassy habitats, such as woodland, marsh, or river banks. Although they dig burrows, they usually build nests above ground.
Reproduction
As an important food source for owls and some other predators, their population peaks and troughs in a four-year cycle. Field voles breed at a great rate, mainly in summer, but often all year round, even under snow. females produce up to seven litters a year, each averaging from four to six young, which are weaned after only 14 days.References:
