Wild primates interact with humans through tourism, research, and conservation programmes. Understanding how these interactions affect welfare guides more responsible approaches.
Wild primate welfare requires ongoing balancing of conservation funding benefits, scientific knowledge generation, and welfare costs of human proximity. The risk of disease transmission from human contact is particularly severe for great apes sharing significant genetic material with humans. Conservation revenue from gorilla and chimpanzee tourism has demonstrably benefited population-level outcomes, creating a welfare trade-off between individual risk from human contact and population benefit from conservation funding. Research with wild primates, when conducted with appropriate welfare safeguards including minimised contact, non-invasive data collection, and veterinary monitoring, can generate knowledge that ultimately benefits both wild and captive populations. Tourist behaviour that violates approach distance restrictions and masking requirements represents the most immediately controllable welfare risk in primate tourism.
