There has been an estimated decline of orangutan well over 50% during the last 60 years (generation length estimated at 20 years, Wich et al. in press). The decline of the species is predicted to continue at this rate, primarily because of forest loss due to conversion of forest to agriculture and fires. The majority of remnant wild populations are located outside of protected areas, in forests that are exploited for timber production or in the process of being converted to agriculture. Last but not least, poaching and the pet-trade remain major threats to across most of Borneo.
