Up Singapore's Tallest Hill

Bukit Timah Hill
Central, Singapore
February 2012

Though much of Singapore's original vegetation had been cleared for logging and cultivation, the forest at Bukit Timah Nature Reserve has remained relatively undisturbed. Likewise, patches of primary rainforest can be seen around the MacRitchie area and Nee Soon Swamp at the Central Catchment Nature Reserve.

These nature reserves are bounded 4 reservoirs - MacRitchie Reservoir, Lower Peirce Reservoir, Upper Peirce Reservoir and Upper Seletar Reservoir. The nature reserves act as water catchment for the reservoirs, in addition, the nature reserves also ensure the quality of water in the reservoirs.

Other than being storehouses of water, today, Bukit Timah Nature Reserve and Central Catchment Nature Reserve are homes to more than 840 flowering plants and over 500 species of animals (including butterflies). With such an astonishing variety of plants, animals and insect life, the nature reserves are indeed treasure houses of Singapore's biodiversity.

Covering an area of approximately 3,043 hectares, both the Bukit Timah Nature Reserve and Central Catchment Nature Reserve are managed by the Central Nature Reserve Branch of the National Parks Board.
