Four Bornean orangutans—Catherine, Dennis, Ames, and Marlon—were officially released into the Kehje Sewen Forest, East Kalimantan, on Thursday (November 5, 2026). This critical conservation effort was led by the Ministry of Forestry through the East Kalimantan Natural Resources Conservation Agency (BKSDA), in collaboration with the Borneo Orangutan Survival (BOS) Foundation and multi-sector partners.
Prior to their return to the wild, the four primates underwent an extensive multi-year rehabilitation process at the Samboja Lestari Orangutan Rehabilitation Center, encompassing medical treatment and natural survival skills training. The program ensures that each orangutan has fully restored its innate wild behaviors to survive independently in its natural habitat.
The release marks a historic milestone, coinciding with the 35th anniversary of the BOS Foundation’s dedication to protecting Kalimantan’s endemic species. Following the release, joint field teams will conduct continuous post-release monitoring (PRM) and habitat security patrols to ensure long-term population recovery across the ecosystem.
