Carbon working group secretariat. Sumatran orangutans are critically endangered and without urgent action could be the first Great Ape species to become extinct. SOS is dedicated to turning this situation around.

Orangutan Working Group Secretariat. Founded in 1990, the Orangutan Foundation is the foremost orangutan conservation organization working actively across the range of both orangutan species.

We work passionately to help secure a world where the needs of wildlife are never an afterthought to the needs for growth, development, profit, sport or greed.

Every morning, we start the day by imagining the orangutan where they belong - wild, free and safe in the flourishing pristine rainforests of Malaysia and Indonesia, fulfilling their role in the preservation of its natural habitat, and safeguarding the survival of its species.

GAP is an international movement that aims to defend the rights of the non-human great primates - chimpanzees, gorillas, orangutans and bonobos, our closest relatives in the animal kingdom.

The Environmental Investigation Agency (EIA) is an independent campaigning organisation committed to bringing about change that protects the natural world from environmental crime and abuse.

Monkey World assists governments around the world to stop the smuggling of primates from the wild. At the Centre refugees of this illegal trade as well as those that have suffered abuse or neglect are rehabilitated into natural living groups.

Our mission is to build a future in which people live in harmony with nature. From our experience as the world's leading independent conservation body, we know that the well-being of people, wildlife and the environment are closely linked. That's why we take an integrated approach to our work.

At The Great Orangutan Project for some years now we prided ourselves on providing the best exclusive volunteer opportunities to help the amazing orangutans of Borneo.
