Adopt an orphaned orangutan
Orangutans are on the brink of extinction. Help provide the care and rehabilitation
they need to return to the wild.
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.

Please enjoy this beautiful video showing how our little orphaned orangutans learn to build nests in Forest School.
Did you know that wild orangutans typically build a new nest every day?
Their nests are woven in branches of trees using broken branches and leaves. They are often very well-crafted, resembling large baskets, and can sometimes be over a meter wide.
Orangutans also build nests in the daytime to rest and play in, and a mother with a young infant might make two or three nests a day. Expectant mothers also use nests to give birth in.
