ONG constituée uniquement d'Indonésiens sensibilisant les populations locales à la déforestation et  à la protection de l'espèce.

Yayasan Orangutan Sumatera Lestari – Orangutan Information Centre (YOSL-OIC) is dedicated to the conservation of the endemic, critically endangered Sumatran orangutans (Pongo abelii) and their forest homes.

We are a local NGO staffed by Indonesian university graduates, believing that Sumatran people are best suited to have an impact in and help save Sumatran biodiversity.

In order to succeed our conservation efforts, we must work with local people towards the preservation and regrowth of rainforest habitat and promote orangutans as global conservation ambassadors for the rainforest ecosystem.
