Pulau Ubin, also called Ubin Island, is an island situated in the north east of Singapore, to the west of Pulau Tekong. Granite quarrying supported a few thousand settlers on Pulau Ubin in the 1960s, but only about a hundred villagers live there today. It is one of the last rural areas to be found in Singapore, with an abundance of natural flora and fauna. The island forms part of the Ubin–Khatib Important Bird Area (IBA), identified as such by BirdLife International because it supports significant numbers of visiting and resident birds, some of which are threatened.
