Yayasan Orangutan Sumatera Lestari

Yayasan Orangutan Sumatera Lestari – Orangutan Information Centre (YOSL-OIC) is a conservation organisation working to protect orangutans and their habitats in Sumatra, Indonesia. Since its establishment, OIC has developed a broad portfolio of conservation programmes in response to the needs of orangutan populations, forests, and local communities across priority landscapes, including the Leuser Ecosystem (KEL), Batang Toru Ecosystem (EBT), and the West Toba landscape. The organisation's purpose is to contribute to resilient landscapes where viable orangutan populations can coexist with local communities. YOSL-OIC combines direct conservation action with community engagement, habitat protection and restoration, livelihood development, research, monitoring, and institutional strengthening. OIC's primary activities are organised around five integrated themes. These include: (1) protection and law enforcement, including forest patrols, wildlife-conflict response, and support for enforcement; (2) ecosystem restoration and recovery, including forest restoration, assisted natural regeneration, nurseries, and rewilding; (3) communities and livelihoods, including sustainable livelihoods, social forestry, and conservation-linked value chains; (4) knowledge and learning, including GIS, biodiversity monitoring, research, communications, and Monitoring, Evaluation and Learning (MEL); and (5) organisational foundations, including institutional development and sustainable conservation finance. A key strength of YOSL-OIC is its emphasis on local participation and community leadership in conservation. The organisation also integrates livelihood interventions with habitat protection, recognising that sustainable livelihoods can create incentives for communities to maintain forests and habitat connectivity. Its restoration work combines field experience and learning-by-doing, while its conservation programmes increasingly seek to apply evidence-based approaches, landscape-level plan.
