Mountain gorillas represent a conservation success story, but the habituation process used for tourism and research creates welfare tradeoffs that deserve careful ethical consideration.
Mountain gorilla welfare sits at the intersection of individual animal welfare and population conservation. Habituation is welfare-costly: the process involves repeated, stressful approaches until gorillas no longer flee. Once habituated, gorillas are perpetually exposed to human presence, losing a key predator-avoidance response and becoming vulnerable to human disease. Respiratory viruses — including human strains of rhinovirus and parainfluenza — have caused fatal pneumonia in gorilla groups. The 7-metre rule is frequently violated by tourists seeking photographs. However, the economic value of gorilla tourism funds the ranger forces that prevent poaching — the existential threat to the population. This creates a genuine ethical tension: welfare costs of habituation may be justified by the survival benefits of funded protection. Best practice includes strict health screening for tourists and guides, mask mandates within 10 metres, and regular veterinary surveillance of habituated groups.
