Wolverines are elusive, wide-ranging carnivores of northern wilderness. Their welfare depends on intact snowpack, large territories, and protection from trapping.
Wild wolverine welfare is threatened by two converging forces: climate change reducing the snowpack they need for denning, and ongoing fur trapping that causes acute suffering through leg-hold trap injuries and prolonged confinement before killing. Female wolverines whose dens are disturbed — by snowmobiles or researchers — abandon kits, causing neonatal starvation. Climate-driven snowpack loss means fewer successful dens each year across the southern edge of their range. Welfare improvements require both climate action (the most fundamental long-term protection) and trapping reform — shifting from indiscriminate leg-hold traps to more selective, less painful killing methods or regulatory protection from trapping entirely.
