Wolverines are wide-ranging, solitary mustelids with enormous home range requirements that make their welfare in zoo settings deeply challenging. Their conservation and zoo management require understanding the limitations of captive environments for this species.
The welfare of wolverines in zoos is inherently compromised by the enormous gulf between their natural ranging behaviour and what even the largest zoo enclosures can provide. Stereotypic pacing is common in captive wolverines deprived of their natural wide-ranging foraging and territorial behaviour. Zoos keeping wolverines must provide maximum possible space, complex terrain with elevation changes, opportunities to dig and cache food, and solitary housing matching their natural social structure. The educational and conservation value of zoo wolverines must be weighed honestly against welfare costs. In situ conservation supporting wild populations and their habitat — particularly snowpack preservation — may offer greater welfare and conservation returns per dollar invested.
