Wolverines are solitary, wide-ranging carnivores with territory requirements that make welfare in zoo settings profoundly challenging. Understanding their needs guides honest assessment of captive suitability.
The welfare case for holding wolverines in standard zoo settings is weak. Their territory requirements exceed anything a zoo enclosure can provide by orders of magnitude; their thermal requirements demand cold-climate facilities; and their solitary nature prevents the social enrichment that partially compensates for space restrictions in social species. The stereotypic pacing observed in captive wolverines is a clear behavioural indicator of chronic frustration. Only institutions with very large, cold-climate naturalistic enclosures that provide genuine complexity for foraging and exploration can justify holding this species on welfare grounds. For most facilities, wolverine display is a welfare compromise that honest assessment would not endorse.
