ABOVE: Floodplain forest growing on Pulau Kaja, an orangutan rehabilitation island in the Rungan /Kahayan rivers near Palangkaraya in Central Kalimantan. Throughout Borneo floodplain forest is usually the richest habitat for fig diversity.
Sg Rungan is a tributary of the mighty Kahayan river which runs just east of the city of Palangkaraya. Pulau Kaja is one of several river islands in the area run by BOS (Borneo Orangutan Survival Foundation) in Central Kalimantan. These islands are used as forested holding areas as part of the long arduous process of preparing rescued orangutans for return to the wild.
