Wild Mink Impact on Water Vole Welfare

American mink are a major predator of water voles in the UK, causing population crashes that threaten this once-common species and create welfare impacts through predation.

Key Facts

Water vole populations have declined by 90% since the 1970s primarily due to mink predation
Mink were released from fur farms and established feral populations across the UK
Mink control programmes using trapping have enabled water vole recovery in managed areas
Water vole reintroductions succeed only where mink are actively controlled
Mink have also devastated ground-nesting bird colonies and other small mammal populations

Welfare Considerations

Mink predation causes acute fear and death for water voles and other native species. The welfare impact of mink on native prey populations is substantial, while mink welfare in control programmes requires humane trapping and monitoring to minimise suffering.

What You Can Do

Support water vole conservation organisations managing mink control programmes
Advocate for humane mink control methods that minimise suffering in trapped animals
Report water vole sightings to your local Wildlife Trust to support population monitoring
