Wild Mountain Gorilla Conservation and Welfare

Mountain gorillas are one of conservation's greatest success stories — their population has grown from 620 to over 1,000 since the 1980s — but each individual's welfare is still profoundly shaped by human decisions.

Key Facts

Mountain gorillas (Gorilla beringei beringei) live only in the Virunga volcanic mountains and Bwindi Impenetrable Forest in central Africa
Their population has increased from approximately 620 in 1989 to over 1,063 as of 2018 census — the only great ape population growing
They live in stable social groups called troops led by a dominant silverback male, with complex social hierarchies
Mountain gorillas are genetically distinct from Eastern lowland gorillas and cannot survive in captivity — no mountain gorilla has ever survived long-term in a zoo
Respiratory diseases transmitted from humans are the leading cause of death — gorillas share approximately 98.6% of human DNA
Gorilla trekking tourism generates approximately $20 million annually for conservation, providing direct economic incentive for protection
Poaching, habitat encroachment, civil conflict and snare injuries remain threats despite population recovery
Research by Dian Fossey Gorilla Fund and others has documented complex social behaviours including grief responses and play

Welfare Considerations

Mountain gorilla welfare is inseparably linked to human activity. Respiratory disease transmission from tourists and trackers — even mild human colds can be fatal to immunologically naive gorillas — is managed through strict protocols (7.5-metre approach limits, masks, maximum 8 tourists per group, one hour maximum visit) but enforcement varies. Snare injuries intended for other species (antelopes, small mammals) cause horrific wounds to gorillas — the Gorilla Doctors veterinary team treats snare injuries but amputations and deaths still occur. Silverback males killed by poachers or human-wildlife conflict leave their troops vulnerable: infanticide by incoming males, group fragmentation and dispersal trauma follow leadership loss. Civil conflict in eastern DRC repeatedly displaces gorilla conservation staff and creates poaching surges. Orphaned gorillas require intensive rehabilitation at Senkwekwe Center — the only mountain gorilla sanctuary — where lifetime semi-captive care is required since release is impossible.

What You Can Do

If you trek mountain gorillas, choose responsible tour operators following strict health protocols and employing local communities
Follow all health guidelines during gorilla treks: masks, 7.5-metre distance, no visit if you feel unwell — your health is their health
Advocate for sustained international funding for gorilla habitat protection and anti-poaching rangers
Support conflict resolution and development initiatives in eastern DRC — political stability directly benefits gorilla conservation
Purchase Rainforest Alliance certified products sourced from gorilla range countries — sustainable agriculture reduces encroachment pressure
