Researching fauna and flora in orangutan habitat, Indonesian Borneo

The tropical forests of Borneo and Sumatra provide far more than just a home for orangutans, they are one of the most biodiverse ecosystems on Earth. Our tropical forest research station, Pondok Ambung, is situated on the banks of the Sekonyer River in Tanjung Puting National Park, Central Kalimantan , Indonesian Borneo.

Orangutan Foundation researchers monitor and track the health of this ecosystem and the species found here. Our drive to promote tropical forest ecology and conservation to Indonesian students, winning their hearts and support, is crucial to the future of the orangutan and Indonesia’s forests.

This blog post provides a snapshot of some of the species studied and the activities undertaken at Pondok Ambung this year. As you will see, many take place after dark.
