Ficus microcarpa is one of the most widespread figs in the world.
The natural distribution extends from South China to Australia and far into the Pacific. Ficus microcarpa is now invasive in many countries including Florida (USA). F. microcarpa is common in cultivation and widely grown as a street tree in many cities from Hong Kong to Sicily Many domesticated varieties are widely planted for landscaping and bonsai.
In Borneo the preferred habitats are brackish swamps and the brackish zone of rivers where they share space with Nipa Palms. In these habitats the trees can grow to a vast size often including hundreds of stilt roots as shown in the photos below from Teluk Kumai , next to Tg Puting National Park, Pangkalan Bun, Central Kalimantan.
