Wolverines are rarely held in zoo collections due to their wide-ranging nature and specialist needs. The few facilities that house them face significant management challenges but serve important conservation roles.
Wolverine welfare in the rare zoo settings that house them faces the fundamental challenge of providing for a solitary, wide-ranging species in confined space. Their large territorial requirements mean that even the most generous zoo enclosure provides a small fraction of their natural ranging needs. Stereotypic behavior — pacing and repetitive patterns — is documented in wolverines with insufficient space or enrichment. Cold climate access is important for a species adapted to subarctic conditions that would experience heat stress in warm-climate facilities. The challenges of wolverine welfare in captivity have led some facilities to question whether wolverines can be housed with adequate welfare, and some have made decisions not to maintain wolverines on these grounds. For facilities that do house them, comprehensive enrichment including large spaces with diverse terrain, food caching opportunities, and scent enrichment from prey species can improve welfare outcomes. Their importance as ambassadors for boreal ecosystem conservation education may justify carefully managed captive programs.
