Our Vision
Our vision is a world where orangutans are free from the threat of extinction and can live in the wild, unharmed by humans.
back to their home.
our two sanctuaries.
The Problem
There are numerous threats to the viability of the remaining wild orangutan population in Indonesia and Malaysia. The primary threat is the loss of habitat with up to 80% of suitable forest in Indonesia and Malaysia having been lost in the past 20 years. Other threats, which often go hand-in-hand with the destruction of the rainforest, are the illegal pet trade and poaching.

When Bumi arrived at our Nyaru Menteng Centre on 18 June 2016, the tiny male was so incredibly weak that he could not even open his eyes. We believe that he was violently separated from his mother shortly after his birth.
But you should see him now! The 'Orangutan Jungle School' star graduated from Forest School with flying colours and is now thriving on a pre-release island.
Please help us in supporting him during this final stage of his rehabilitation journey so he can return to his true wild home soon!
