Legal trapping of wolverines in Canada and Russia causes acute pain and prolonged suffering. Understanding trapping welfare issues helps advocates push for stronger protections for this wide-ranging mustelid.
Wolverine trapping represents a significant and largely invisible welfare concern. Trapped wolverines experience acute pain from limb compression and potential injury, followed by prolonged confinement stress that can last days in cold, exposed conditions. The psychological distress of a wide-ranging, highly active predator confined to a trap radius is substantial. Death from trapping may be prolonged if killing traps malfunction or if the animal dies from hypothermia, injury, or stress rather than the trap mechanism itself. Bycatch — the incidental capture of non-target species — adds welfare harm beyond the target population. The Agreement on International Humane Trapping Standards establishes performance criteria for traps, but enforcement and adoption are inconsistent. In jurisdictions where wolverines have no special protection status, there are no minimum welfare standards specifically applied to their capture. This gap between welfare science and regulatory practice warrants advocacy attention.
