How Many Gorillas Are in Uganda? Understanding the Population
Uganda is home to approximately half of the world’s remaining mountain gorillas, making it one of the most important countries on Earth for the survival of this critically endangered species. As of the most recent census data from 2018 and updated estimates for 2026, Uganda’s mountain gorilla population stands at roughly 459 individuals. These gorillas live exclusively in two protected areas in southwestern Uganda: Bwindi Impenetrable National Park and Mgahinga Gorilla National Park. Understanding these numbers, how they have changed over time, and what they mean for conservation provides essential context for anyone planning a gorilla trekking safari in the Pearl of Africa.
The Global Mountain Gorilla Population
The total global population of mountain gorillas is estimated at approximately 1,063 individuals as of 2024. This represents one of the most remarkable conservation success stories of the past century. In the early 1980s, when primatologist Dian Fossey was working in Rwanda, the global population had dwindled to fewer than 250 individuals. Today, thanks to intensive conservation efforts spanning three decades, the population has more than quadrupled. Mountain gorillas remain the only great ape species whose population is increasing in the wild, a testament to the effectiveness of targeted conservation when properly funded and sustained.
Uganda’s Share: Bwindi and Mgahinga
Of the 1,063 mountain gorillas remaining, Uganda hosts approximately 459 in Bwindi Impenetrable National Park and a small additional number in Mgahinga Gorilla National Park. Bwindi alone contains about 430 individuals, divided among approximately 50 family groups. Some of these families are habituated for tourism, while others remain wild and are studied purely for research purposes. The gorillas in Bwindi represent a distinct subpopulation from those in the Virunga Massif, which spans Rwanda, Uganda, and the Democratic Republic of Congo.
How Scientists Count Gorillas
Gorilla census work is extraordinarily demanding. Teams of trackers, researchers, and veterinarians spend weeks in the forest, following trails, recording nest sites, and collecting faecal samples for genetic analysis. Each individual gorilla can be identified by its unique nose print, similar to human fingerprints. The most recent full census of Bwindi’s gorillas was conducted in 2018, and the next comprehensive count is expected in the near future. In the interim, routine monitoring by Uganda Wildlife Authority trackers provides ongoing population estimates.
Population Trends and Conservation Impact
The mountain gorilla population has grown steadily since the dark days of the 1980s. This recovery is directly attributable to conservation interventions including habitat protection, anti-poaching patrols, veterinary intervention for sick and injured gorillas, community engagement programmes, and the regulated tourism that generates funding for all of these activities. Without gorilla trekking tourism, which contributes millions of dollars annually to conservation and local communities, this population recovery would not have been possible.
How Tourism Helps the Population Grow
Every gorilla permit purchased contributes directly to conservation. The Uganda Wildlife Authority allocates a significant portion of permit revenue to anti-poaching patrols, ranger salaries, community development projects, and veterinary care for the gorillas. Revenue sharing programmes ensure that local communities living around the parks benefit economically from gorilla conservation, reducing the incentive for activities like poaching and encroachment into gorilla habitat.
Final Thoughts
Uganda’s 459 mountain gorillas represent a fragile but growing population that has become a symbol of what dedicated conservation can achieve. When you trek to see these extraordinary animals, you are not merely observing wildlife; you are participating in a conservation success story that has brought a species back from the brink of extinction. The number may seem small, but every individual matters, and every visitor who purchases a permit plays a direct role in ensuring that this number continues to grow.
