Wolverines are wide-ranging, solitary mustelids with extraordinary territorial requirements. Captive management struggles to accommodate their physical and psychological needs in standard zoo enclosures.
Wolverines represent one of the greatest welfare challenges in carnivore management. Their natural ranging requirements are so large that no zoo enclosure can provide adequate space, and their solitary disposition makes social housing a source of stress rather than enrichment. Welfare-centred facilities accept these constraints and focus on maximising within-enclosure complexity through substrate for digging, elevated climbing structures, varied scent stimulation, and food caching opportunities. The strongest welfare case is for keeping wolverines only where there is a clear conservation justification, with welfare rigorously monitored through behavioural indicators and stereotypy tracking.
