Mountain Gorilla Conservation in Tanzania 2026: Status & Efforts

Mountain Gorilla Conservation in Tanzania: Quick Answer

Mountain gorillas do not inhabit Tanzania itself; they are confined to high-altitude forests in the Greater Virunga region spanning Rwanda, Uganda, and the Democratic Republic of Congo (DRC). However, Tanzania plays a vital role in transboundary conservation collaboration. The global mountain gorilla population has recovered to over 1,000 individuals—the only great ape species with an increasing population—thanks to decades of ranger protection, anti-poaching patrols, and cross-border partnerships . The species was downlisted from Critically Endangered to Endangered in 2018, a milestone achieved despite ongoing civil conflict, habitat loss, and disease threats in the region .

Why Mountain Gorilla Conservation Matters to Tanzania

Although mountain gorillas live in forests above 2,400 metres (8,000 feet) elevation in the Virunga Volcanoes and Bwindi Impenetrable National Park—territories shared by Rwanda, Uganda, and the DRC—Tanzania's government and conservation organisations are integral to the transboundary frameworks that protect them . The International Gorilla Conservation Programme (IGCP), established in 1991 as a joint effort of the African Wildlife Foundation, Fauna & Flora International, and the World Wildlife Fund, works across all three countries to coordinate ranger patrols, habitat management, and community engagement .

Tanzania's commitment to the Greater Virunga Landscape collaboration demonstrates how regional cooperation can succeed even during armed conflict. As Dr. Andrew G. Seguya, Executive Secretary at Greater Virunga Transboundary Collaboration, explains: "As the sentries to the conservation estate, our rangers play an important role of protecting our conservation assets. Working with surrounding communities to enlist community support for conservation and guiding us through these precious lands to see, enjoy and understand the balance of nature that has to be so dearly preserved" .

The Mountain Gorilla: Species Profile

The mountain gorilla (Gorilla beringei beringei) is a subspecies of the eastern gorilla, distinguished by its thick, dark fur—an adaptation to cold, high-altitude environments. Adult males (silverbacks) weigh up to 440 lbs and stand 4–5.5 feet tall . Their habitat is restricted to two isolated forest regions: the Virunga Massif (shared by Rwanda, Uganda, and DRC) and Bwindi Impenetrable National Park in Uganda, which adjoins the Sarambwe Nature Reserve in DRC .

Mountain gorillas have never been hunted for bushmeat by local communities, a cultural factor that has been critical to their survival. However, they are often caught in snares set by poachers targeting antelope, and historically, infants have been abducted for illegal sale to zoos and as pets—a process that frequently results in the deaths of protective adult gorillas .

Population Recovery: A Conservation Success Story

The mountain gorilla population has demonstrated steady growth despite decades of regional instability:

Year/Period	Population (Virunga Massif)	Global Total	Status
1971	~275 individuals	~275	Critically Endangered
1980	~254 individuals	~254	Critically Endangered
2010	480 individuals	~800–900	Critically Endangered
2016	604 individuals	~1,000+	Endangered (downlisted 2018)
2018–2026	604+ (stable/growing)	1,000+	Endangered

The 2010 census documented a 26.3% increase in the Virunga population over the previous seven years , and the 2016 census across the entire Virunga landscape confirmed continued growth. This trajectory is extraordinary: mountain gorillas are the only great ape species whose population is increasing .

Key Threats to Mountain Gorillas

Poaching and Human Snares

Although mountain gorillas are not traditionally hunted for bushmeat, they remain vulnerable to wire snares set by poachers targeting smaller game. Rangers working in Virunga and surrounding areas remove approximately 1,000 snares annually . Gorillas caught in these traps suffer injuries that can lead to infection and death. Additionally, the illegal trade in infant gorillas for zoos and private collections has historically driven poaching, as capturing an infant often requires killing protective adults .

Habitat Loss and Climate Change

Mountain gorillas occupy a fragmented habitat already under pressure from agricultural expansion, logging, and human settlement. Climate change intensifies this threat: as global temperatures rise, suitable forest habitat at high elevations shrinks, forcing gorillas to compete for space in already densely populated areas . The Virunga region's forests are disappearing, leaving little room for population expansion or genetic exchange between isolated groups.

Armed Conflict and Human Instability

The Greater Virunga Landscape has been affected by decades of intermittent civil unrest in the DRC and Rwanda. Despite this, conservation efforts have persisted—a testament to ranger dedication. Virunga National Park alone has lost over 175 rangers in the line of duty while protecting the park from armed conflict, habitat destruction, and poaching . Armed groups sometimes exploit protected areas for resources, and ranger safety remains a constant concern.

Disease Transmission

Habituated gorillas—those accustomed to human presence for research and tourism—face elevated risk of disease transmission from visitors. Respiratory viruses, in particular, pose a significant threat to the species . The Mountain Gorilla Veterinary Program (MGVP) treats gorillas for conditions including respiratory infections, but prevention through strict visitor protocols remains critical .

Conservation Programmes and Key Organisations

International Gorilla Conservation Programme (IGCP)

The IGCP, founded in 1991 and comprising the African Wildlife Foundation, Fauna & Flora International, and the World Wildlife Fund, is the primary coordinating body for mountain gorilla conservation across Rwanda, Uganda, and the DRC . The IGCP works with national park authorities, local communities, and ranger teams to:

• Conduct population censuses (most recently in 2016 across the entire Virunga landscape)
• Provide ranger training and monitoring equipment
• Support anti-poaching patrols and habitat management
• Develop community enterprises (beekeeping, handicrafts, tourism lodges) to generate local revenue from conservation

Ranger Protection and Monitoring

Rangers are the frontline of mountain gorilla conservation. In Bwindi Mgahinga Conservation Area, rangers like Bernard spend 6+ hours daily with gorilla groups, beginning patrols at 6:30 AM and trekking more than 3 hours through forest to reach their assigned family . Their daily tasks include:

• Checking gorilla nests to count group members
• Examining feces for signs of disease
• Physical health assessments of individual gorillas
• Behavioural observation and reporting

Nelson Guma, Chief Park Warden of Bwindi Mgahinga Conservation Area, emphasises that "Rangers are guardians of our wildlife gems that are a National heritage. They habituate gorillas as a conservation approach so that they can monitor and protect them better" . The increase in mountain gorilla population and the 2018 downlisting from Critically Endangered to Endangered is largely credited to ranger dedication .

Mountain Gorilla Veterinary Program (MGVP)

The MGVP provides critical health care to wild mountain gorillas, treating diseases such as respiratory viruses that can spread from humans to apes . This programme ensures that habituated gorillas used in research and tourism receive preventative care and emergency treatment.

Dian Fossey Gorilla Fund International (DFGFI)

DFGFI, which traces its lineage to Dian Fossey's pioneering research in Rwanda, continues to protect gorillas through ranger training, education, and support for conservation leaders at the University of Rwanda . The organisation has maintained gorilla conservation partnerships for over two decades.

Virunga National Park (Democratic Republic of Congo)

Virunga National Park, which straddles the DRC–Rwanda–Uganda border, is home to approximately one-third of the world's mountain gorilla population . Despite extreme challenges—including armed conflict and resource scarcity—Virunga has maintained its conservation programme without pause, employing the highest international standards of ranger protection and veterinary care . The park's success reflects the commitment of the Congolese Institute for Nature Conservation (ICCN) and its ranger corps.

Transboundary Collaboration: The Model for Success

One of the most remarkable aspects of mountain gorilla conservation is its transboundary framework. The Greater Virunga Landscape spans three countries with different governance systems, languages, and histories—including the 1994 Rwanda genocide, which killed approximately 800,000 people and devastated conservation efforts . Yet conservation organisations and park authorities have maintained collaboration through regular meetings, joint planning, and coordinated anti-poaching operations .

This model has proven effective: mountain gorilla populations have increased over 25 years despite civil wars in the region . Regular coordination between wardens from Rwanda, Uganda, and the DRC has enabled better habitat protection, ranger training sharing, and disease monitoring. As Anna Behm Masozera, interim director of IGCP, notes: "It's not that the threats and dangers have diminished, it's that conservation efforts are succeeding in abating those threats. That's the result of years of partnership and cooperation among the wildlife authorities of all three countries" .

Community Engagement and Sustainable Livelihoods

Mountain gorilla conservation depends on local support. For decades, the IGCP has partnered with communities bordering protected areas to develop sustainable enterprises that generate income from gorilla conservation without harming the species. These initiatives include:

• Gorilla Tourism: Permits to trek mountain gorillas in Virunga, Volcanoes (Rwanda), and Mgahinga (Uganda) generate significant revenue, with tourism fees directly funding ranger salaries, park management, and community development projects
• Virunga Artisans: A cooperative that markets handmade products from communities near Volcanoes, Mgahinga, and Bwindi National Parks, providing alternative income
• Beekeeping and Honey Production: Community-led enterprises that reduce pressure on forest resources while generating household income
• Luxury Tourist Lodges: Locally operated tourism facilities that employ community members and share revenue with conservation initiatives

Revenue-sharing from gorilla tourism has been transformative. Communities neighbouring parks have become direct beneficiaries, which has encouraged greater participation in conservation . Rwanda's Kwita Izina (gorilla naming ceremony), held annually since the early 2000s, has become a cultural celebration that strengthens national pride in gorilla conservation and reinforces local commitment to protection .

Results: Progress and Ongoing Challenges

Conservation Wins

• Population Growth: The global mountain gorilla population has grown from approximately 254 individuals in 1980 to over 1,000 today
• IUCN Status Downlisting: In 2018, the mountain gorilla was downlisted from Critically Endangered to Endangered—the first downlisting since 1994
• Stable Virunga Population: The Virunga Massif population has grown from 480 (2010) to 604 (2016) and remains stable
• Only Increasing Great Ape: Mountain gorillas are the only great ape species with a growing population, demonstrating that intensive conservation can work

Persistent Threats and Challenges

Despite these successes, mountain gorillas remain a conservation-dependent species vulnerable to rapid population collapse:

• Small Population Size: With only 1,000+ individuals across two isolated forest regions, the species is susceptible to epidemics, genetic bottlenecks, and stochastic events
• Habitat Fragmentation: The two gorilla populations (Virunga and Bwindi) are isolated from each other, preventing genetic exchange and limiting expansion
• Ongoing Poaching: Although snare-related deaths have declined, poaching pressure persists, particularly in remote areas
• Climate Change: Rising temperatures are shrinking suitable high-altitude habitat, forcing gorillas into increasingly crowded spaces
• Disease Risk: Habituated gorillas face disease transmission risks from tourists and researchers, as demonstrated by respiratory virus outbreaks
• Regional Instability: Armed conflict in the DRC and broader political instability threaten ranger safety and conservation funding
• Competing Wildlife Declines: While mountain gorillas have recovered, many other species in the Greater Virunga Landscape—including lions, hippopotamuses, and elephants—are in decline and face extinction risk

How Responsible Tourism Supports Mountain Gorilla Conservation

Visitors to the Greater Virunga region can contribute directly to gorilla conservation through responsible tourism. Gorilla trekking permits generate revenue that funds:

• Ranger salaries and equipment (patrol gear, communication devices, medical supplies)
• Anti-poaching operations and law enforcement
• Veterinary care and disease monitoring
• Community development projects in villages bordering protected areas
• Educational programmes that strengthen local conservation ethics

Best practices for responsible gorilla trekking include:

• Maintain Distance: Stay at least 7 metres (23 feet) from gorillas to reduce disease transmission risk
• Follow Ranger Instructions: Guides and rangers are trained to minimise gorilla stress and ensure visitor safety
• Health Screening: Visitors with respiratory infections should postpone treks to protect gorillas
• Book Through Registered Operators: Use established safari operators and park authorities to ensure permit fees support conservation
• Support Community Enterprises: Purchase from Virunga Artisans and locally owned lodges to strengthen community investment in gorilla protection

Visitors can explore multi-country safari itineraries that combine gorilla trekking with broader East African wildlife experiences. SafariFind offers curated packages that connect conservation-minded travellers with verified operators committed to habitat protection and community benefit.

Frequently Asked Questions

Are mountain gorillas found in Tanzania?

No. Mountain gorillas are confined to high-altitude forests (2,400–4,000 metres) in the Virunga Volcanoes and Bwindi Impenetrable National Park, which are located in Rwanda, Uganda, and the Democratic Republic of Congo. Tanzania does not have a native mountain gorilla population. However, Tanzania is part of the Greater Virunga Transboundary Collaboration and supports regional conservation efforts through partnerships with the International Gorilla Conservation Programme.

How many mountain gorillas are left in the world?

As of 2026, the global wild mountain gorilla population is estimated at over 1,000 individuals. The Virunga Massif population reached 604 individuals in 2016 and remains stable. This represents a remarkable recovery from approximately 254 individuals in 1980. Mountain gorillas are the only great ape species with an increasing population.

What is the conservation status of mountain gorillas?

Mountain gorillas are classified as Endangered by the IUCN Red List. In 2018, they were downlisted from Critically Endangered—the first downlisting since 1994. This change reflects decades of successful conservation efforts, though the species remains conservation-dependent and vulnerable to rapid population collapse due to its small size and habitat fragmentation.

Why are mountain gorillas endangered?

Mountain gorillas face multiple threats: habitat loss due to agricultural expansion and logging; poaching (snare traps set for other animals); disease transmission from humans to habituated gorillas; climate change reducing high-altitude forest; armed conflict in the Greater Virunga region; and isolation between the two remaining populations (Virunga and Bwindi), which prevents genetic exchange. Their small total population of 1,000+ individuals makes them vulnerable to epidemics and stochastic events.

What organisations protect mountain gorillas?

The primary coordinating body is the International Gorilla Conservation Programme (IGCP), established in 1991 by the African Wildlife Foundation, Fauna & Flora International, and the World Wildlife Fund. Other key organisations include the Mountain Gorilla Veterinary Program (MGVP), Dian Fossey Gorilla Fund International (DFGFI), Virunga National Park (DRC), and the Greater Virunga Transboundary Collaboration. These groups work with national park authorities, ranger teams, and local communities across Rwanda, Uganda, and the DRC.

How do rangers protect mountain gorillas?

Rangers conduct daily patrols starting at 6:30 AM, trekking 3+ hours to reach gorilla groups. They monitor nest sites, examine feces for disease, assess individual health, and record behavioural changes. Rangers also remove poaching snares (approximately 1,000 per year in Virunga), provide veterinary alerts, and habituate gorillas for research and tourism—which enables closer monitoring and protection. Rangers work in dangerous conditions, with over 175 killed in the line of duty at Virunga alone.

How does gorilla tourism help conservation?

Gorilla trekking permits generate significant revenue that directly funds ranger salaries, anti-poaching operations, veterinary care, and community development projects in villages bordering protected areas. Tourism has given mountain gorillas economic value, making them worth protecting. Revenue-sharing schemes ensure local communities benefit, strengthening their commitment to conservation. However, habituated gorillas face increased disease transmission risk, so strict visitor protocols (distance, health screening, group size limits) are essential.

What is transboundary collaboration in gorilla conservation?

Transboundary collaboration involves park authorities and conservation organisations from Rwanda, Uganda, and the DRC coordinating ranger patrols, habitat management, disease monitoring, and anti-poaching efforts across shared borders. Regular meetings and joint planning enable conservation success despite civil conflict and political differences. This model has proven effective: mountain gorilla populations have grown over 25 years despite regional instability, largely because of transboundary cooperation and gorilla tourism revenue.

Can I visit mountain gorillas responsibly?

Yes. Gorilla trekking in Virunga (DRC), Volcanoes National Park (Rwanda), and Mgahinga Gorilla National Park (Uganda) is available through registered operators. Responsible practices include maintaining 7+ metres distance from gorillas, following ranger instructions, not visiting if you have respiratory infections, and booking through established operators to ensure permit fees support conservation. Purchasing from community enterprises like Virunga Artisans and locally owned lodges strengthens local investment in gorilla protection.

What are the main threats to mountain gorillas today?

Current threats include habitat loss from agricultural expansion and climate change; poaching via snares intended for other animals; disease transmission from humans to habituated gorillas; armed conflict in the Greater Virunga region; and population fragmentation (the two gorilla populations cannot interbreed). Although conservation efforts have reduced some threats, the species remains vulnerable due to its small total population (1,000+) and dependence on intensive protection.

How has the mountain gorilla population changed since 1980?

The mountain gorilla population has recovered dramatically: from approximately 254 individuals in 1980, to 480 in 2010 (a 26.3% increase over seven years), to over 1,000 by 2016. The Virunga Massif population specifically grew from 480 (2010) to 604 (2016) and has remained stable since. This recovery, despite decades of civil conflict, poaching, and habitat loss, is considered one of Africa's greatest conservation achievements.

Why are mountain gorillas conservation-dependent?

Mountain gorillas remain conservation-dependent because their small population (1,000+), habitat fragmentation, isolation from genetic exchange, and vulnerability to disease and armed conflict mean they cannot survive without intensive protection. They require daily ranger monitoring, anti-poaching patrols, veterinary care, habitat management, and transboundary coordination. Without these ongoing efforts, the population could collapse rapidly. The species' continued existence depends entirely on sustained human commitment to conservation.
