Wild Wolverine Fisher Trapping Welfare: Improving Capture Methods

Fisher and wolverine trapping for fur uses methods with significant welfare concerns, and regulatory reform and alternative methods are advancing humane trapping standards.

Key Facts

Fisher (Pekania pennanti) and wolverines are trapped for fur across North America, with millions of traps set each season across boreal and mountainous regions
Conventional foothold (leghold) traps cause acute injuries including soft tissue damage, fractures, and in severe cases degloving of trapped limbs
The Agreement on International Humane Trapping Standards (AIHTS) establishes killing trap standards but many countries have not fully implemented them
Certified Trapper Education programmes in many US states and Canadian provinces include basic welfare standards but implementation varies widely
Cable restraints and box traps offer alternatives to foothold traps with lower injury rates, though they are not suitable in all terrains
Trap check interval requirements — how frequently trappers must inspect traps — vary from 24 hours to several days between jurisdictions

Welfare Considerations

Trapping welfare depends critically on trap type, placement, and check frequency. Animals caught in foothold traps and not found for 24-72 hours suffer prolonged stress, injury, and in cold weather, frostbite or hypothermia. Self-directed mutilation of trapped limbs has been documented. Even killing traps, if not correctly sized or placed, may injure rather than kill, leaving animals in prolonged suffering. Non-target captures — including endangered species, domestic dogs, and non-furbearer wildlife — add to the welfare burden. Regulatory reform requiring shorter trap check intervals, Certified Humane Trapping standards for killing traps, and expanded use of cable restraints would meaningfully reduce trapping welfare harms.

What You Can Do

Avoid purchasing products made from wild-trapped fur, particularly from regions without humane trapping standards
Support campaigns for mandatory short trap check intervals and certified humane trapping standards in your jurisdiction
Advocate for fisher and wolverine population protections in areas where populations are at risk
Choose trapping permit systems that require Certified Trapper Education with welfare components
Support research into cage and cable trapping alternatives that reduce injury rates compared to foothold traps
