Wild Water Vole Population Recovery

Water voles are the UK's fastest declining mammal, with recovery efforts providing welfare and conservation benefits.

Key Facts

Water vole populations declined by about 90% in the UK between 1970 and 1998
American mink predation is the primary driver of population collapse
Mink management through trapping combined with reintroduction has restored populations in some areas
Bank vegetation and burrowing substrate quality determine carrying capacity for recovered populations

Welfare Considerations

Water voles experiencing mink predation pressure face chronic threat with limited escape. Mink predation kills entire colonies rapidly. Recovery programmes through mink management restore safe habitat where water voles can fulfil natural behaviours without extreme predation pressure.

What You Can Do

Support water vole recovery projects through local wildlife trusts
Report water vole sightings and mink presence to recording schemes
Avoid releasing American mink into the wild - this is illegal and harmful
