The population of orangutan in Sebangau National Park according to WWF-Indonesia are 5,826 individuals (WWF Central Kalimantan, 2015). Based on that number, the population is the largest within conservation areas in Central Kalimantan. Although based on Population and Habitat Viability Assessment Orangutan (2016) using Vortex Analysis, this number will last for next 100 years, there will be an effort to connect the orangutan habitat to other habitats so that the survival of this population is maintained.
