Mountain Gorilla Threats in 2025 — What Still Puts the Species at Risk
The reclassification of the mountain gorilla from Critically Endangered to Endangered by the IUCN in 2018 — based on the first census to show a population exceeding 1,000 individuals — is genuinely good news, but it does not mean the species is safe. “Endangered” still means a species facing a high risk of extinction in the wild without continued conservation effort. Understanding the specific threats that remain active in 2025 — some of which are decreasing, some of which are stable, and some of which are increasing — provides the context for appreciating why the conservation programme that gorilla tourism funding supports is still necessary.
Wire Snare Poaching
The primary direct threat to individual mountain gorillas in habituated populations is not deliberate gorilla poaching — killing a gorilla for bushmeat or trophies is actively managed against by the armed ranger forces in Rwanda, Uganda, and the Bwindi-accessible parts of Congo. The primary threat is wire snares set for small antelope — duiker, bushbuck — that injure gorillas who blunder into them. Gorillas are large enough to break out of most wire snares, but the wire loop tightens on the hand or foot as the animal pulls free, and the resulting wound, if untreated, progresses to deep infection that can produce disability or death.
The Gorilla Doctors veterinary programme at Volcanoes National Park and Bwindi exists primarily to address this threat — snare removal from injured individuals requires veterinary sedation and treatment that park rangers cannot provide without veterinary training. The ranger teams’ daily patrol programmes, which remove snares from the forest before they injure animals, are the preventative complement to the veterinary intervention that treats injuries after they occur.
Respiratory Disease
Respiratory disease transmitted from humans to gorillas remains the most significant cause of mortality in habituated gorilla families — the same respiratory pathogens that produce mild illness in human visitors or local community members can produce fatal pneumonia in gorillas whose immune systems have no evolved defence against them. The seven-metre distance rule, the illness exclusion policy, and the mask requirement (now standard at some parks) are all direct responses to this threat. The documented cases in which gorilla deaths in habituated families have been linked to human respiratory pathogens — not merely suspected, but confirmed through genetic sequencing of pathogen samples — make this threat one of the best-evidenced in gorilla conservation medicine.
Habitat Fragmentation
The mountain gorilla’s habitat — the Virunga volcanic range and Bwindi’s ancient forest — is surrounded by some of the most densely populated agricultural land in Africa. Rwanda’s Northern Province, Uganda’s southwest highlands, and the relevant eastern DRC provinces all have population densities that produce continuous agricultural encroachment pressure on the park boundaries. At Volcanoes National Park, the park boundary is a fence line between forest and potato field — the transition from gorilla habitat to agricultural land is not gradual; it is a sharp edge that exists because of active boundary management. Any weakening of that management — through boundary encroachment, agricultural fires that escape into the forest margin, or the settlement pressure that inevitably accompanies high population density — reduces the available gorilla habitat and increases edge effects on the forest interior.
The Eastern Congo Security Situation
The most significant ongoing threat to the Virunga gorilla population that cannot be directly managed by conservation programme investment is the armed conflict in eastern Congo’s North Kivu province, where Virunga National Park is located. The M23 conflict, the presence of multiple armed groups in the Kivu region, and the periodic involvement of national military forces in active combat within or adjacent to the park territory have produced conservation management disruption, ranger security risk (over 200 Virunga rangers have been killed in the line of duty since 1996), and direct threats to the gorilla families whose ranges overlap with areas of active armed group movement. This threat is not addressable by gorilla tourism revenue or conservation programme management — it requires the political and security stabilisation of eastern Congo, which remains unresolved in 2025.
