The Borneo Orangutan Survival Foundation

Thousands of orangutans have been killed or displaced due to human development activities causing habitat loss.

The BOS Foundation focuses on orangutan rescue, rehabilitation, reintroduction and long-term conservation. We have rescued thousands of orangutans over the past two decades and currently care for approximately 800 orphaned orangutans at our Centres in Central and East Kalimantan.

We now need your help to release the remaining 800 orangutans in our care. No matter how big or small your support, you make a difference to their future!

With thanks for your support and warm wishes from all at the BOS Foundation
