Wolverines are low-density apex predators of northern boreal and alpine ecosystems whose welfare and conservation status are threatened by climate change, trapping, and habitat fragmentation in their remaining range.
Wild wolverine welfare is threatened by habitat degradation and direct mortality from trapping. Wolverines caught in leg-hold traps experience acute pain and distress that may last hours or days before trappers check their lines. Even non-lethal catch-and-release research trapping causes physiological stress and behavioral disruption. At the population level, climate-driven snowpack reduction threatens reproductive success: females that cannot establish subnivean (under-snow) dens for birthing have lower reproductive rates, and the cubs that die from exposure represent individual welfare losses as well as population decline. The combination of low population density, large territory requirements, and climate vulnerability makes wolverines one of North America's most at-risk carnivore species.
