Field Voles in the UK
Field vole (Microtus agrestis) is a common small rodent in the UK and an important part of grassland life. It has a short tail, round face and coarse brown fur, and moves in runways through thick tussocky grass. Field voles eat grasses, sedges, herbs and sometimes bark in winter. They breed fast from March to October, with several litters and young that can breed at three to four weeks. Predators include barn owls, kestrels, foxes, stoats and grass snakes, so predator numbers often follow vole numbers. Look for winding grass runways, small round droppings, stems cut at a 45 degree angle and tiny burrow holes. Managing rough grassland, field margins and hedgerows helps keep vole numbers up and supports birds of prey and other wildlife.
