Wolverines are wide-ranging carnivores of boreal and arctic ecosystems that face growing pressure from trapping, climate change, and human encroachment. Their welfare in the wild is shaped by their need for vast undisturbed territories and cold snowpack habitat.
Wolverine welfare suffers acutely from trapping and snaring, which remain legal across much of their range. Leghold traps cause serious injuries including broken teeth, dislocated limbs, and severe stress from immobilisation; wolverines may struggle in traps for hours or days before a trapper returns. Climate change creates compounding welfare harms: reduced snowpack shrinks denning sites, food caching becomes less reliable, and kits born in shallow snow dens face higher mortality from temperature exposure. Road mortality, as wolverines attempt to maintain large home ranges through increasingly fragmented landscapes, adds further individual suffering. Reintroduction efforts in areas like Colorado require careful welfare monitoring during capture, transport, and post-release acclimatisation.
