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.

Brilliant work!
One of the greatest teams I have ever had the pleasure of working with. You do incredible things for Orangutans 🦧 🫶🫶
Thank you BOS for the work you have done. Rescuing these helpless, kidnapped orangs was "Mission Impossible" and BOS have not only rescued, but repatriated and rehabilitated them to give them every chance of life in the wild! Amazing achievements like this are why I support BOS 🙂
Look at her go ❤️❤️❤️
You're amazing!! 🦧❤️
