Pulau Sipandan is a small c. 10 ha atoll  (the remnant of a volcano)  situated in 600 m deep water in the Makassar sea trench which runs between Borneo and Sulawesi.

The Makasar Strait is the worlds most important faunal and floral divide  popularly known as Wallace’s Line.

Sipadan island was declared a bird sanctuary by the British colonial government of North Borneo in 1933 and the original vegetation has never been seriously disturbed. In this way Sipadan is exceptional among all the small islands of East Borneo. Sipadan is  also exceptionally rich in strangling figs with large numbers of both Ficus microcarpa and Ficus glandifera.  Ficus glandifera  is several times more common than F. microcarpa on Sipadan.

Pulau Sipadan is 600 meters long and 300 meters wide at the widest point. The total area is c. 10 ha.

The black area top left is 600 m deep ocean. The white specks are dive boats above the drop off where diving is most popular. Sipadan is considered one of the world’s top dive sites.

Sipadan is still largely covered in virgin beach forest including many large fig trees. When fruiting these fig trees attract large numbers of rare nomadic island pigeons.
