Wolverines are solitary, wide-ranging carnivores of the boreal and alpine zone. Climate change is shrinking their snowpack-dependent habitat, creating welfare challenges for one of the wilderness's most resilient species.
Wolverine welfare is fundamentally linked to snowpack persistence — a resource that climate change is systematically eliminating. Female wolverines require deep, persistent snow for natal dens where pups are born and protected through early development. As spring snowpack disappears earlier, den sites are compromised, pup survival declines, and females face reproductive failure. At the individual level, climate-driven habitat compression forces wolverines into smaller, more marginal territories with reduced prey availability. Trapping for fur in Canada and Alaska adds direct welfare harm through trap injuries and prolonged suffering in steel-jawed traps. The combination of climate impacts on reproduction and direct trapping mortality creates a serious welfare situation for remaining wolverine populations.
