With a BSc in Environment, Economics and Ecology, Sarah has long been fascinated with the challenge of balancing human needs and environmental protection.
Numbers of the critically endangered mountain gorilla are on the up, following conservation efforts in the transboundary Virunga Massif, one of the two remaining areas where the great ape is still found.
Survey results released today reveal that numbers in this area have increased to 604 from an estimated 480 in 2010, including 41 social groups along with 14 solitary males in the transboundary area. This brings the global wild population of mountain gorillas to an estimated 1,004 when combined with published figures from Bwindi Impenetrable National Park (where the rest of the subspecies is found) and makes it the only great ape in the world that is considered to be increasing in population.
The findings are the result of intensive surveying coordinated by the Greater Virunga Transboundary Collaboration and supported by the International Gorilla Conservation Programme (IGCP – a coalition programme of Fauna & Flora International and WWF) along with other partners.
The census involved twelve teams – comprising people from more than 10 institutions – which covered over 2,000 km of difficult, forested terrain systematically searching the mountain gorilla habitat for signs of the animals, recording nest sites and collecting faeces samples for genetic analysis. The teams also looked for evidence of threats to gorillas and other wildlife.
Despite this good news, the survey found that direct threats from wire or rope snares persist. During the surveys, the teams found and destroyed more than 380 snares, which were set for antelope but can also kill or harm gorillas. One of the snares discovered by the teams contained a dead mountain gorilla.
There are also new threats looming large on the horizon, including climate change, infrastructure development and the ever-present spectre of disease, which has the potential to devastate the remaining populations.
Ongoing conflict and civil unrest also present an ongoing risk, impacting people and wildlife. A number of rangers have been killed in recent weeks in the Democratic Republic of Congo’s Virunga National Park.
Alison Mollon, Director of Operations for Africa at Fauna & Flora International (FFI), said: “Since FFI first began working to protect mountain gorillas in the 1970s, we have seen a remarkable transformation in the fortunes of this great ape, which at that time was on the very precipice of extinction. This turnaround is thanks to the extraordinary efforts of all those who have persisted through immense challenges – sometimes even risking their own lives – to protect these great apes.
“Today, mountain gorilla numbers are looking much healthier, but this is no time for complacency. We need to remain extremely vigilant, particularly in light of the ever-present and growing threat posed by the transmission of human-borne diseases that are relatively innocuous for us, but potentially fatal to other primates.”
Sir David describes his famous encounter with mountain gorillas and the genesis of the International Gorilla Conservation Programme (IGCP) - filmed in 2015.
Reacting to the news, Fauna & Flora International vice-president and WWF UK ambassador, Sir David Attenborough said: “When I first visited the mountain gorillas in 1979, the situation was dire; the number of these remarkable animals was dreadfully small. It is incredibly heartening therefore to see how the efforts of so many different groups – communities, governments, NGOs – have paid off. The threats to mountain gorillas haven’t disappeared entirely, of course, so now the challenge must be to ensure that these achievements are sustained long into the future.”
The survey results underscore the need for continued attention and action by government agencies, protected area staff, tourism operators, tourists and communities alike, to ward off these threats and keep mountain gorillas safe in the long term.
Fauna & Flora International is grateful to the players of People’s Postcode Lottery for their ongoing support to protect mountain gorillas and other threatened species and habitats around the world.
How have we achieved such a remarkable turnaround for mountain gorillas, and what remains to be done?
The 2015/2016 Virunga Massif mountain gorilla census was conducted by the Protected Area Authorities in the Democratic Republic of Congo, Rwanda, and Uganda (l’Institut Congolais pour la Conservation de la Nature, the Rwanda Development Board and the Uganda Wildlife Authority) under the transboundary framework of the Greater Virunga Transboundary Collaboration.
The census was supported by the International Gorilla Conservation Programme (a coalition programme of Fauna & Flora International and WWF), the Max Planck Institute for Evolutionary Anthropology, the Dian Fossey Gorilla Fund, Institute of Tropical Forest Conservation, Gorilla Doctors, and the North Carolina Zoo.
The census was funded through generous contributions from Fauna & Flora International, WWF, and Partners in Conservation at the Columbus Zoo & Aquarium. Additional financial support to the census science committee provided by Berggorilla & Regenwald Direkthilfe.
