About the Sumatran Orangutan Society (SOS)

ORAS 023788

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. We do this by:

Supporting grassroots projects which empower local people to become guardians of the rainforests

Restoring damaged orangutan habitat through tree planting programmes.  

Campaigning on issues threatening the survival of orangutans in the wild.

Raising awareness about the importance of protecting orangutans and their rainforest home.

SOS works to find local, national and international solutions to the root causes of deforestation. Our ultimate aim is to protect, extend and secure the habitat of wild orangutans to stabilise and grow the population.

Help us protect orangutans, their forests and their future.

History 

SOS was established in 1997 by the late Lucy Wisdom. In 2001, SOS co-founded the Orangutan Information Centre (OIC) in Sumatra, a grassroots non-profit organisation staffed by passionate and dedicated Indonesian conservationists, led by Panut Hadisiswoyo. The OIC is our main partner organisation in Sumatra, and together we strive to change the fate of the critically endangered Sumatran orangutan.
