Wild Wolverine Trapping Welfare and Management

Wolverines are incidentally caught in traps set for other species, causing significant suffering, and targeted trapping raises both welfare and conservation concerns for this low-density species.

Key Facts

Wolverines are taken incidentally in traps set for wolves, coyotes, lynx, and other fur-bearing mammals across their range
Foothold and leghold traps can cause severe injuries including broken bones, joint damage, and soft tissue trauma when animals struggle
Wolverines have extremely low population densities — fewer than 300 individuals are estimated in the contiguous US
Montana, Idaho, and Wyoming permit wolverine trapping despite population concerns, while Canada has broader take
Check intervals for traps are often 24-72 hours, leaving injured animals in pain for extended periods
Trap designs that reduce injury and kill more quickly are increasingly recommended but adoption is inconsistent
The precautionary principle is particularly relevant for wolverines given their low density and climate vulnerability

Welfare Considerations

Wolverines caught in traps — whether targeted or incidental — experience acute pain from injuries and prolonged distress awaiting death or release. The welfare case against trapping wolverines is strong given both the severity of injury in typical trap types and the conservation status of the species. More humane trap designs with shorter check intervals reduce but cannot eliminate the welfare burden. From both welfare and conservation perspectives, a moratorium on wolverine trapping in the contiguous US is a reasonable and proportionate precautionary measure given population uncertainties.

What You Can Do

Support campaigns advocating for wolverine trapping moratoriums in the contiguous United States
Advocate for mandatory use of certified humane trap designs and shorter trap check intervals where trapping is permitted
Donate to wolverine population monitoring programs that provide data to support evidence-based management decisions
Oppose legislation that would weaken wolverine protections or expand trapping in range states
Support wilderness corridor conservation that maintains the large unfragmented landscapes wolverines need
