Wolverine: Alpine Specialist Threatened by Snow Loss

Wolverines depend on deep snow for denning and caching food, making them one of the most climate-vulnerable large mammals in North America and Europe.

Key Facts

Wolverines cache food under snow for months, relying on persistent snowpack
Females need snow depth of at least 1.5 meters to create safe birthing dens
Range is contracting northward as climate change reduces snow-covered days
Estimated 15,000 wolverines remain across boreal and alpine regions globally
Also threatened by trapping in some jurisdictions and habitat fragmentation from roads

Welfare Considerations

Den disturbance can cause mothers to abandon kits in freezing conditions. Insufficient snowpack forces females to find alternative sites or fail to reproduce. Trapping causes injury and prolonged suffering. Wolverines are solitary and wide-ranging, making them sensitive to habitat fragmentation.
