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.

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.

A #throwback to when Valentino, known for being the class clown, was still at Forest School.
Now, he is just one step away from enjoying life in freedom, practising his skills on a Pre-Release Island.
He is an enthusiastic explorer, eagerly venturing across different areas of the island as he moves from one feeding platform to another.
Way to go, Valentino!
