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.

This week marks the anniversary of Topan's rescue!
Eight years ago, she was confiscated from a local village by forestry authorities and brought to BOS Foundation's Nyaru Menteng centre.
Upon arrival, Topan was in an extremely weak state, suffering from severe dehydration and malnutrition. Villagers claimed to have found her alone by a riverbank, which is hard to believe since a mother orangutan would never willingly abandon her infant.
Thanks to the excellent medical care of our BOS veterinarians, Topan's condition improved, and she was soon able to join other infants in the Baby House.
Today, Topan is a brave, resilient, and assertive individual. She successfully graduated from Forest School and is currently honing her survival skills on Bangamat Pre-Release Island.
We are so incredibly proud of Topan! With a symbolic adoption, you can help this remarkable female orangutan take her final steps toward a life of freedom!
Please adopt her here:

Do you remember our beloved Kopral, the #orangutan with no arms?
Kopral is our #superhero when it comes to determination, resilience and a positive attitude.
Last year, he seriously injured his right foot, which is extremely tragic for a double-arm amputee who depends on his feet to live a self-determined life.
Come and check in with us to find out how his recovery is progressing here:
