Gorillas in accredited zoos provide conservation genetics value and public engagement, but their welfare depends critically on social grouping, space and psychological enrichment.
Well-managed gorilla groups in modern zoo facilities show largely positive welfare indicators — strong social bonds, play behaviour, exploration and grooming. The cardiovascular disease problem, linked to low physical activity compared to wild foraging lifestyles, is addressed in leading zoos through dietary management and indoor-outdoor activity programmes. Gorilla welfare in zoos has improved substantially through accreditation requirements and dedicated husbandry research. In the wild, poaching and habitat loss cause acute welfare harm alongside population decline.
