Background

The largest species of vole in Britain, the European Water Vole is sometimes confused with a Brown Rat, who inhabit the same environment. Within their burrows, Water Voles, are known to create escape paths in case of predator attack.

Habitat

Water Voles live in most European counties with the primary exceptions of Portugal and Spain. They live by riverbanks.

Diet

A herbivorous creature the water vole feeds on riverside plants and leaves. Very occasionally they feed on insects and other small invertebrates.

Predators & Threats

Their approximated range has dropped by about 90% in Britain due to habitat loss and degradation of riverside habitats. Like many small mammals, the water vole is preyed on by foxes, large birds, stoats, minks, owls and otters. In the Scottish highlands golden eagles also pose a threat.
