Wolverine populations face welfare threats from habitat fragmentation, climate-driven snowpack loss affecting denning and human persecution in livestock areas.
Wolverine welfare is threatened by the intersection of habitat requirements that are themselves under threat from climate change. The dependence on persistent spring snowpack for successful denning means that individual female welfare — and kit survival — is directly affected by climate conditions. Territory size requirements mean wolverines are particularly vulnerable to habitat fragmentation, with individuals forced into contact with human activities more frequently than species with smaller ranges. Trapping welfare concerns are significant for a species whose low reproductive rate means each individual lost has disproportionate population impact. Conservation of wolverine welfare requires both habitat connectivity and snowpack preservation through climate action.
