Wolverines in zoo settings have extreme habitat requirements reflecting their vast wild ranges, and inadequate space is the primary welfare challenge for captive individuals.
Wolverines present one of the most challenging welfare cases in zoo management: they are wide-ranging, spatially complex animals whose behavioral needs cannot be fully met in typical zoo enclosures. The stereotypic pacing seen in poorly housed wolverines is a clear welfare indicator reflecting inadequate space and environmental complexity. Best-practice wolverine exhibits are large, complex, cold, and designed around the natural caching and scent-marking behaviors of the species. Wolverines serve an important role in zoo programs — maintaining a captive safety net population for a species threatened by climate change — but this conservation value must be matched by genuine welfare investment.
