We are a non-profit conservation and research organisation working for over 20 years in the rainforests of Borneo. We partner with local stakeholders to implement landscape conservation strategies based on rigorous scientific research, and support communities to develop sustainable livelihoods that complement environmental protection. Our longest-running programme, in Sebangau Forest, was founded in 1999 as the Orangutan Tropical Peatland Project (OuTrop). We identified Sebangau as home to the largest orangutan population in lowland Borneo, bringing the region to the forefront of orangutan conservation efforts and resulting in the award of National Park status in 2004. In 2016, we created Borneo Nature Foundation to extend our reach and tackle conservation challenges across Borneo. We expanded our projects in Sebangau and established our Rungan Programme, working to protect 156,000 hectares of vital orangutan habitat. We launched our Barito Ulu Programme in 2018, working in the Heart of Borneo to revive research and conservation in the spectacularly bio-diverse and yet unprotected rainforests of northern Central Kalimantan.
