Orangutans


Common Name: Bornean orangutan; Orangoutan de Borneo(Fr); Orangután de Borneo(Sp)

Scientific Name: Pongo pygmaeus
Habitat: Tropical and Subtropical Moist Broadleaf Forests
Location: Borneo
The Bornean orangutan is now recognized as a different species from its Sumatra relative. Three subspecies are recognized: Pongo pygmaeus pygmaeus, P.p. morio, and P. p. wurmbii, the most common Bornean subspecies. Although extensive, the latter's habitat is increasingly fragmented in the remaining swamp and lowland dipterocarp forests of Central and West Kalimantan.

It is estimated that about one third of Borneo's orangutan populations were lost during the 1997/98 forest fires. On the Indonesian side of Borneo, populations of this subspecies are not faring well either.

Although some populations live inside protected areas, illegal logging still takes place within these area and hence remains a major threat to the survival of this species.
