Wolverines are wide-ranging carnivores with exceptionally large territory requirements. Climate change threatens the deep snowpack they depend on, creating urgent conservation and welfare concerns.
Wolverines are among the animals most acutely threatened by climate change in terms of welfare impact. Their dependence on deep, persistent snowpack for denning means that warming temperatures directly undermine their ability to successfully raise young. Female wolverines excavate natal dens up to 5 metres deep in snow, where kits are protected from cold and predators. As snow disappears earlier each spring, kit survival rates fall. Beyond climate, wolverines face welfare threats from trapping (addressed separately), habitat fragmentation by roads, and human disturbance near den sites. Their exceptionally large territory requirements mean they cannot persist in small protected areas without landscape-scale connectivity. Population recovery requires both climate action and maintaining or restoring large wilderness areas with minimal human disturbance.
