Mountain gorillas are the only great ape species with an increasing wild population, driven by intensive conservation investment — a success story with lessons for other critically endangered species.
Mountain gorilla conservation represents a rare success story that illuminates what intensive, well-funded, individual-level conservation can achieve. Unlike many wildlife conservation programs that focus exclusively on habitat protection, the mountain gorilla program includes veterinary intervention for injured and sick individuals, removal of snares, and treatment of respiratory infections. These individual-level welfare interventions have made measurable contributions to population recovery. Tourism brings conservation funding but requires strict disease prevention protocols — gorillas share 98% of human DNA and are highly susceptible to human respiratory diseases. Each tourist group is limited in size and proximity, and visitors showing any illness are excluded. The program demonstrates that combining habitat protection, anti-poaching enforcement, and individual welfare interventions produces better population outcomes than habitat protection alone.
