Factsheet P23: Voles

Voles can strip bark from stems and roots of young trees, easily killing them as a consequence. The field vole (Microtus agrestis) is a common resident of rough grassland. Its presence is indicated by a network of runs, containing small piles of grass clippings and droppings, on or just below the surface of the ground. Bank voles (Clethrionomys glareolus) are much less common.
