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.

It definitely was an amazing experience. It has long been on my bucket list, and I finally decided to just book it and do it. So glad I did. I learnt so much, and knowing that all of the volunteers combined efforts are helping the every day lives of these beautiful animals warms my heart. When you look at what you get, for the price, this far outweighs destination holiday, and you go home knowing you have enriched these animals lives.

I have just returned from the once in a lifetime experience. If you are thinking about doing it, stop thinking and secure your place. You will be so disappointed if life happens and you never get the opportunity.
Today, we celebrate World Wetlands Day. This year's theme, "Wetlands and Traditional Knowledge: Celebrating Cultural Heritage," holds special significance for us.
With numerous hectares of precious peat swamp forest under our care, we greatly value the traditional knowledge and support of the indigenous communities surrounding our work areas.
For us, environmental conservation begins with the local communities. By protecting Indonesia's unique ecosystems, including its vital wetlands, we also help preserve the livelihoods and traditions of the people who call this country home.
