Sumatran Orangutan Society

Northern Sumatra’s rainforests are irreplaceable. They are some of the most important forests on the planet, home to rare Tapanuli & Sumatran orangutans and other precious species. Supporting thousands of forest-edge communities, these ecosystems are key in the global fight against climate change.

Our mission is to protect orangutans, their forests and their future. We aim to do this via our three goals:

PROTECT - We work to keep existing rainforests secure and stable, ensuring a home for Sumatran and Tapanuli orangutans to enable their existing communities to thrive.
CONNECT - We work to create ""corridors"" between fragmented areas of rainforest so that groups of orangutans are not isolated from each other.
REWILD - We work to help degraded rainforest landscapes to recover by healing the land and planting a diverse range of trees and other fauna, creating even more space for orangutans to thrive.
