Welfare requirements for captive chimpanzees including social group management, enrichment and the critical role of retirement sanctuaries.
Captive chimpanzees represent a legacy welfare challenge created by decades of research use that produced populations of individuals unable to return to the wild and requiring lifetime care. The welfare needs of traumatized research chimpanzees are complex, requiring not just physical care but psychological rehabilitation from the damage caused by isolation, invasive procedures and inadequate social opportunity during years of laboratory housing. Retirement sanctuaries that provide appropriate social groups, complex enrichment and trauma-informed care represent the most welfare-positive solution for this population, but require sustained financial support from the institutions and industries that created the welfare debt. The ongoing funding gap in chimpanzee sanctuary care is itself a welfare problem requiring advocacy and philanthropic attention.
