The East Kalimantan Orangutan Reintroduction Program at Samboja Lestari was the first orangutan reintroduction program established by the Borneo Orangutan Survival (BOS) Foundation in 1991, specifically to provide care and rehabilitation for displaced or orphaned orangutans rescued from areas of habitat loss. Formally known as Wanariset, the project was relocated in 2006, due to insufficient space and was renamed Samboja Lestari. The program is currently located about 38 kilometers from Balikpapan, in East Kalimantan and we work in collaboration with the East Kalimantan Conservation and Natural Resources Authority (BKSDA), an executive technical unit of the Indonesian Ministry of Environment and Forestry. The land at Samboja Lestari is owned by the BOS Foundation and is the location of our forest rehabilitation program. Our main activities at Samboja Lestari include orangutan rescue, translocation of orangutans from areas of conflict to areas of secure and protected habitat, the provision of welfare and healthcare, rehabilitation, reintroduction and forest restoration activities. In addition to orangutan rehabilitation and reintroduction, we manage sun bear sanctuary at Samboja Lestari, with around 50 sun bears currently under in our care. Conservation of habitat and wildlife can only be achieved by working together with local communities and other stakeholders, hence in all areas of our work we engage with local communities and schools on community development activities and outreach conservation education. etc. The BOS Foundation has rescued hundreds of orangutans in East Kalimantan and currently cares for and supports over 100 orangutans at Samboja Lestari.
