Wolverines require vast, remote territories and face mounting pressure from habitat fragmentation, trapping, and climate change that reduces the snowpack essential for their reproduction.
Wolverines face welfare harms from both direct persecution and the systemic loss of the cold, remote habitat they depend on. Trapping causes acute suffering — wolverines caught in leg-hold traps may struggle for many hours before a trapper arrives, suffering injuries and extreme distress. The loss of deep, persistent snowpack through climate change threatens not just reproduction but the very ecological relationships wolverines depend on for survival: winter-killed ungulate carcasses become less available as prey populations shift and snow conditions change. Road mortality is increasing as wolverines are forced to cross developed areas to maintain connectivity between habitat patches. The combination of direct mortality from trapping and road kill, compounded by climate-driven habitat loss, creates a compounding welfare and conservation challenge requiring coordinated action.
