For the first time in recorded history, the mountain gorilla population has officially passed 1,100 individuals. The result, confirmed in early 2026 from the most recent census conducted jointly across the Virunga Massif, spanning Rwanda, Uganda, and DRC, and Uganda’s Bwindi Impenetrable Forest, marks the culmination of nearly four decades of conservation work and stands as one of the only genuine great ape recovery stories on the planet. Mountain gorillas, Gorilla beringei beringei, remain the only great ape subspecies whose population is currently and consistently increasing, and the 2026 figure is the clearest evidence yet that the model built around gorilla trekking tourism is working.
For anyone planning a gorilla trekking trip to Uganda or Rwanda, this milestone is worth understanding, both because it is a genuinely remarkable conservation story and because it directly explains why your trekking permit fee matters.
The Numbers Behind the Milestone
The population is now roughly split between two strongholds. Approximately 459 to 500 gorillas live in Uganda’s Bwindi Impenetrable National Park, while the remaining 500-plus inhabit the Virunga Massif, the cluster of volcanoes straddling Rwanda’s Volcanoes National Park, Uganda’s Mgahinga Gorilla National Park, and DR Congo’s Virunga National Park. Together, these two populations now total over 1,100 individuals, up from just 1,004 recorded in the 2018 census, itself already considered a landmark result at the time.
How Far the Population Has Come
The scale of the recovery only becomes clear against the historical record. In the early 1980s, mountain gorillas were teetering on the edge of extinction, with an estimated population of just 250 individuals across their entire range, decimated by poaching, habitat loss, and civil conflict throughout the region. By 1989, the population had climbed to around 620. By 2010, it reached 786. By 2018, it crossed 1,000 for the first time. And now, in 2026, it has passed 1,100.
| Year | Estimated Population |
|---|---|
| Early 1980s | ~250 |
| 1989 | ~620 |
| 2010 | ~786 |
| 2018 | ~1,004 |
| 2026 | 1,100+ |
This trajectory represents one of the most successful large-mammal conservation turnarounds ever documented, achieved not through isolation from human contact but through a carefully managed model of regulated, high-value tourism combined with intensive on-the-ground protection.
What’s Actually Driving the Recovery
Several factors have compounded over decades to produce this result. Sustained anti-poaching enforcement across all three range countries has dramatically reduced snaring and direct killing. Community-based conservation programmes, funded substantially by gorilla permit revenue, have given communities bordering the parks genuine economic alternatives to poaching and forest encroachment, turning former threats into active conservation partners. Veterinary care for injured or sick gorillas, delivered by dedicated teams who monitor habituated families daily, has caught and treated problems, from snare injuries to respiratory illness, that would previously have gone unaddressed and often fatal.
Our detailed piece on how gorilla trekking tourism directly funds this conservation model walks through exactly how permit fees translate into ranger salaries, patrols, and community programmes on the ground.
What the Census Actually Involves
Counting mountain gorillas is a painstaking, multi-month undertaking. Survey teams comb the entire range in sweeps, tracking gorilla groups through indirect signs including nests, dung, and feeding trails, and in many cases collecting genetic samples that allow researchers to distinguish individual gorillas even without direct sightings. This method, refined over successive censuses, gives conservationists a far more reliable population estimate than simply counting known habituated families, since it also captures gorillas in unhabituated, wild groups that tourists never see.
The census is conducted jointly by wildlife authorities and conservation partners across all three range countries, reflecting the reality that mountain gorillas move freely across the shared Virunga Massif regardless of national borders.
What This Means for Your Gorilla Trek
A larger, healthier population does not mean unlimited access. Daily permit numbers remain strictly capped, eight trekkers per habituated family for standard treks, regardless of overall population size, because the limiting factor has always been the number of gorilla families safely habituated for tourism, not raw population numbers. If anything, a growing population increases the case for booking early, since rising visitor demand is already outpacing permit supply in peak months.
What does change is the broader context of your trip. Trekking today means visiting a population that is measurably, provably thriving, not one hanging on by a thread, a genuinely different emotional experience from gorilla tourism a generation ago.
A New Chapter for the Newest Gorillas
Some of the most recent additions to this record-breaking population are the very gorillas being named at Rwanda’s Kwita Izina 2026 ceremony on 4 September, and in Uganda, the newly split and habituated Happy gorilla family in Bwindi’s Ruhija sector, a direct, tangible sign of a population still growing and forming new social groups.
Frequently Asked Questions About the 2026 Gorilla Census
How often is the mountain gorilla census conducted?
Censuses are conducted periodically, roughly every five to eight years, given the scale and difficulty of the survey work involved across three countries and dense mountain forest terrain.
Does the growing population mean more gorilla families will open for trekking?
Population growth can eventually support additional habituated families over time, as seen with Bwindi’s newly added Happy family in 2026, though habituation is a slow, careful multi-year process and each new family is added cautiously.
Are all 1,100+ gorillas available for tourists to see?
No. Only habituated families, acclimatised over years to human presence, are open to trekking. Many gorillas in the wider population live in unhabituated groups that are monitored for research and protection but never visited by tourists.
Does my permit fee actually contribute to this conservation success?
Yes, directly. The majority of gorilla permit revenue in both Uganda and Rwanda is reinvested into ranger salaries, anti-poaching patrols, veterinary care, and community programmes, the same combination of factors credited with driving the population’s recovery.
Is the population expected to keep growing?
Conservationists are cautiously optimistic, though continued growth depends on sustained funding, political stability across the three range countries, and continued community support, none of which can be taken for granted.
Why the Recovery Is So Rare in Conservation
Population recoveries of this scale among large, slow-reproducing mammals are exceptionally uncommon globally. Female mountain gorillas typically give birth only once every four to six years, and infant mortality in the wild remains a real factor even under close protection, meaning population growth of this magnitude reflects decades of consistently low mortality from human threats rather than any change in the species’ naturally slow reproductive rate. Compare this to most other great ape populations worldwide, nearly all of which continue to decline due to habitat loss, poaching, and disease, and the mountain gorilla’s trajectory stands out as a genuine outlier success story in modern conservation.
Researchers attribute this specifically to the combination of intensive, individualised daily monitoring of habituated families, something made financially possible by tourism revenue, and sustained political commitment to conservation across Uganda, Rwanda, and, where security allows, DRC.
Frequently Asked Questions About the 2026 Gorilla Census
Who actually conducts the census?
The census is a joint effort involving wildlife authorities and conservation partners across Uganda, Rwanda, and DRC, coordinated to account for gorilla groups that move across national borders within the shared ecosystem.
How accurate are census figures?
Modern census methods combining physical survey sweeps with genetic sampling are considered highly reliable, though as with any wildlife census across dense, difficult terrain, figures represent a best estimate rather than an exact headcount.
Does population growth mean gorillas could be removed from the endangered list?
Despite the encouraging trend, mountain gorillas remain classified as endangered given their still-limited range, ongoing habitat pressure, and vulnerability to disease and political instability in parts of their range.
Which country’s population grew fastest?
Both the Bwindi and Virunga Massif populations have shown sustained growth, though exact comparative growth rates vary by census period and are best confirmed through the detailed published census reports.
How does this compare to other great ape populations globally?
Mountain gorillas stand out as the only great ape subspecies with a consistently increasing population; nearly all other great ape populations, including other gorilla subspecies, chimpanzees, and orangutans, continue to decline.
What Comes Next for Gorilla Research
With the population now confirmed above 1,100, researchers are shifting some focus toward long-term genetic diversity monitoring, ensuring the recovering population remains healthy at a genetic level and not just numerically. Continued individual monitoring of habituated families, the same daily tracking that makes gorilla trekking possible, remains central to this next phase of research, meaning tourism and science continue to reinforce each other as the population grows.
Comparing the Two Population Strongholds
While both the Bwindi and Virunga Massif populations have grown, they differ meaningfully in habitat and management context. Bwindi’s population lives within a single, contiguous national park under one national authority, while the Virunga Massif population ranges across three separate national parks under three different governments, adding a layer of cross-border coordination complexity that Bwindi’s researchers do not face. That both regions have nonetheless achieved sustained growth speaks to the strength of the underlying conservation model across genuinely different administrative circumstances.
A Milestone Worth Sharing
Crossing 1,100 is not just an internal conservation metric; it is the kind of clear, quotable milestone that helps sustain public and donor interest in a decades-long conservation effort. Round, historic numbers like this play a real role in maintaining the funding and political attention gorilla conservation depends on for the next chapter of recovery.
