North American Wolverine Welfare and Climate Threats

North American wolverines depend on persistent spring snow for denning and are among the species most threatened by climate warming.

Key Facts

Wolverine kits are born in snow dens in late winter
Spring snow persistence is essential for kit survival and development
Climate models predict loss of suitable habitat across much of wolverines current range
Trapping for fur remains legal in several Canadian provinces
Wolverines were recently listed as threatened under the US Endangered Species Act

Welfare Considerations

Loss of spring snow causes den collapse and kit mortality, representing significant suffering at the population level. Trapping causes prolonged pain and distress. Wolverines have extremely large territories and low population densities; any mortality has disproportionate population impacts. Climate stress may increase exposure to pathogens as ranges shift.
