Habitat
The orang -utans live in tropical rain forest areas,
usually river boundaries or mountain ranges over
6,500 feet. In Malaysia, orang-utans are found in
undisturbed and protected forests to the northern
and eastern regions of Sabah's interior. The
largest and least disturbed areas that still harbour
comparatively large populations of orang-utan in
Sabah are the eastern interiors in the Sandakan
district, particularly along the Lokan river and the
tributaries of the upper Kinabatangan and upper
Segama river. Their range also extended
southwards across the political boundaries into
Kalimantan.
