The Leuser Ecosystem contains a richness of biodiversity that is unrivalled in Southeast Asia. It is estimated that approximately 54% of terrestrial animals on the island of Sumatra can be found inside this incredible ecosystem.

The last place on earth

The Leuser Ecosystem is the last place on earth where orangutans, rhinos, elephants and tigers still roam together in the wild. These four charismatic species are all Critically Endangered and it is believed that the Leuser Ecosystem is the last hope for the survival of these species in Southeast Asia.

Rare species

Other species include the sun bear, white-handed gibbon, siamang, macaque, loris, lutung, clouded leopard, Asian golden cat, binturong, hornbills, falcons, pheasants, parrots, king cobra, python, turtles and tortoises.

Of over 170,000 protected sites worldwide, the Leuser Ecosystem ranked 14th most irreplaceable for mammals in general, and 21st for threatened mammals according to the journal Science.
