Due to ongoing urbanisation, there is currently no choice but to cull each year a number of longtail macaques (Macaca fascicularis).

Monkey Island is a planned rescue center set in the natural environment of one of Singapore's southern islands, Pulau Tekukor, where the displaced macaques are offered a unique and humane alternative. The island will be an international center for habitat research and for educational and eco tourism.

Monkey Island is the result of the interaction between PhiloZoophie and AVA, WRS, Nparks, NUS, NTU, SDC, STB and a board of advisors comprising international environmentalists, business experts, and education and tourism experts.

Monkey island is a national liability turned into an asset.
