Wild Water Vole Habitat Restoration

Water voles have suffered the fastest decline of any UK mammal species, losing 90% of their population since the 1970s due to mink predation and habitat loss.

Key Facts

UK water vole population fell from around 8 million in the 1970s to fewer than 875,000
American mink, escaped from fur farms, are the primary cause of decline
Mink management using cage traps can protect local water vole populations where sustained

Welfare Considerations

Water voles living in mink-exposed habitats exist under constant predation pressure that affects normal behaviour including foraging and reproduction. Mink can pursue voles underwater into their burrows, making the entire burrow system unsafe. Water voles in high-mink-density areas show elevated stress markers and reduced reproductive success. The species requires both habitat and sustained mink management to recover welfare at population level.

What You Can Do

Support Wildlife Trusts running mink management programmes for water vole recovery
Create bankside vegetation including rushes and sedges on waterside property
Report water vole sightings to your county recorder to track population recovery
Volunteer for mink raft monitoring programmes in your local area
