Wolverines are elusive, wide-ranging mustelids whose welfare in the wild is threatened by trapping, habitat fragmentation, and climate-driven loss of deep snow habitat essential for denning.
Wolverine welfare in the wild is compromised by both direct and indirect human pressures. Trapping with leghold or Conibear traps causes acute pain and suffering — animals may remain trapped for days before the trapper returns to check the line, and non-target species are frequently caught as bycatch. The wolverine's specialized dependence on deep spring snow for denning makes them acutely vulnerable to climate warming — failed denning events leave kits exposed to fatal temperature extremes. Habitat fragmentation from roads, development, and recreation infrastructure disrupts the vast ranges wolverines need. In areas where they encounter livestock, wolverines are sometimes killed as perceived threats. Conservation measures that address these pressures — including trapping reform, climate action, and corridor protection — are essential to sustaining wolverine populations and the welfare of individual animals.
