Justification
There has been an estimated decline of over 80% over the last 75 years (assuming a generation length of at least 25 years; Wich et al. in press). This decline continues, as forests within its range are under major threat. Most orangutans are outside of protected areas, including within potential logging areas and conversion forests. After a period of relative stability, pressure on these forests is increasing once again as a result of the recent peace accord, and a dramatic increase in demand for timber and other natural resources after the December 2004 tsunami.
