Derived from the Malay words for “person of the forest," Sumatran orangutans are critically endangered.
Historically, the species' population was found over the entire island of Sumatra and further south into Java. Now, you will only find the Sumatran orangutan in the provinces of North Sumatra and Aceh. The population is threatened by hunting and habitat loss.
Females give birth to just one infant at a time every eight or nine years, making their populations very susceptible to even very low levels of hunting. Despite legal protection since 1931, orangutans are still captured and kept in households as status symbols, or hunted for food in some areas.
Orangutan habitat is being lost at an extremely high rate, mainly due to fire and conversion of forests to oil palm plantations and other agricultural development. Read more here.
