Humans are pushing mountain gorillas out of the wild and into extinction.

The biggest threats to this endangered great ape's survival come from political instability, human encroachment, and forest degradation. Only about 1,000 of these great apes remain in the wild, according to the most recent census. Their sanctuary in Virunga National Park is fertile and rich in biodiversity making it one of the most populated regions in Africa. As people move closer to these endangered apes, they also bring the risk of human diseases such as the flu, pneumonia, and even Ebola. Increasing human populations and continued encroachment pose serious threats to this great ape's habitat.

A future marred by conflict.

War in the Democratic Republic of Congo has resulted in more than four million human lives lost over the past 14 years. The political instability and pressure from rebel groups throughout the area put pressure on Virunga National Park, placing this great ape in the middle of this social and economic crisis.

Locals depend on natural resources and wildlife-based tourism for their welfare, which closely links the ape's future with peace and prosperity through the land.


We are protecting this iconic, endangered ape from extinction:

Work with partners

In 2018, African Wildlife Foundation purchased land directly adjacent to Volcanoes National Park and donated it to the Rwandan government to expand great ape habitat. During the past seven years, this great ape’s populations have shown an increase of 26.3 percent. This expansion is the beginning of providing adequate habitat for the world’s most endangered ape.

Benefits from working with locals and tourism

AWF works with locals to help both great apes and communities. Through partnerships with private operators and communities, we have designed and constructed tourism lodges benefitting the apes of Rwanda and Uganda—and their respective communities. The Sabyinyo Silverback Lodge, in the foothills of the Virunga Mountains, and Clouds Mountain Gorilla Lodge, outside of Bwindi Impenetrable Forest, are community-owned tourism lodges that benefit the local people who share their backyard with great apes by generating income through tourism. In 2016, Volcanoes National Park generated $16.4 million from park entry fees. It’s efforts like these that will continue to help develop livelihood strategies that complement conservation.

Engage a variety of conservation methods

We have protected apes on the ground through ranger-based monitoring, transboundary collaboration, community and tourism development, anti-poaching activities, and habitat conservation. By undertaking a multi-pronged approach to conservation, we are able to engage on multiple fronts to protect this endangered species and its habitat.
