Wild Wolverine Climate Change Vulnerability

Wolverines depend critically on deep spring snow for den insulation, making them one of the most climate-vulnerable mammals in North America.

Key Facts

Female wolverines require persistent spring snowpack for den insulation through June
Wolverines have one of the smallest ranges projected under climate change models
They occupy high-altitude and high-latitude habitats across the Northern Hemisphere
Prey availability and reproduction both depend on persistent snow conditions
US population estimates range from 300 to 1,000 individuals

Welfare Considerations

As spring snow disappears earlier, wolverine mothers face impossible choices between den site fidelity and providing thermal insulation for cubs. Early snow melt exposes cubs to lethal cold. Range contraction from climate change forces wolverines into smaller, more fragmented areas with increased territorial conflict and reduced food availability.
