Every year more than a million hectares of rainforest fall victim to legal or illegal overexploitation around the world. Orangutans are still losing habitat and remain threatened with extinction. For almost 30 years, we have been fighting directly on the ground to conserve orangutans in Sumatra and protect their habitat, the remaining tropical rainforest, whilst at the same time promoting sustainable livelihoods among surrounding communities.


What we want to achieve

Secure wild orangutan populations and healthy, sustainable ecosystems in Sumatra.
