Chimpanzee sanctuaries provide lifetime care for orphaned and former pet or research chimpanzees. Meeting the complex social, cognitive, and spatial needs of chimpanzees in sanctuary settings is one of the most challenging welfare tasks in animal care.
Sanctuary chimpanzees carry significant welfare histories before arrival. Infants rescued from bushmeat hunters have witnessed violent death, experienced prolonged stress and malnutrition during transport, and lost the constant maternal contact that is developmentally essential. Former pets may have spent years in social isolation, deprived of conspecific interaction and exposed to human disease. Former research chimpanzees may have experienced repeated medical procedures under restraint. At sanctuaries, the primary welfare challenge is providing sufficient social complexity, space, cognitive stimulation, and autonomy for animals with cognitive needs approaching those of humans. Successful sanctuaries achieve genuine welfare improvements — chimpanzees in stable social groups with enriched environments show positive welfare indicators including play, exploration, and social bonding.
