Wild Water Vole Mink Predation and Recovery

Water vole populations collapsed following American mink escapes from fur farms, with mink control essential for recovery.

Key Facts

Water vole populations declined by 95% in the UK between 1990 and 2010
American mink, escaped from fur farms, can decimate entire water vole colonies within a season
Coordinated mink removal across river catchments enables water vole recovery within 2-3 years
Mink rafts and traps are the primary control tool, requiring regular checking and humane dispatch
Water vole reintroduction from captive-bred populations requires prior mink removal to succeed

Welfare Considerations

Mink predation on water voles causes population collapse through repeated predation events, den invasions and persecution of breeding females. The welfare implications of mink control - trapping and killing - must be weighed against the welfare of the vastly greater number of water vole lives saved. Welfare-conscious trap management minimises time in trap for captured mink.

What You Can Do

Support mink control programmes operated by wildlife trusts on suitable river systems
Advocate for regulations against escape of invasive predators from fur farms
Report water vole sightings to local recording groups to identify recovery hotspots
Support habitat creation and bank restoration that supports water vole populations
