The Jalan Gemala area at Lim Chu Kang is as remote and wild as it can possibly get on the island of Singapore. Set along the banks of the upper reaches of the Sungei Kranji, once a tidal river lined with rich mangrove forests up to the extent of the tidal influence, it finds itself at the edge of a reservoir of freshwater, created by the damming of the mouth of the Kranji River.
The river itself had in the past been one that served as a communication link, bringing in settlement to an area where early gambler plantations had been established. An area of mangroves – the river was lined with the watery forests up to the limits of the tidal influence, it now supports an area of freshwater marshes, wet grasslands and secondary woodland that is teeming with bird, plant and insect life – it is thought to support a colony of fireflies.
The area was one of two identified in the 2013 Land Use Plan and subsequently the URA Master Plan for conservation as Nature Areas – the other being Pulau Unum and Beting Bronok. The Land Use Plan has this to say about the area:
Jalan Gemala at Lim Chu Kang has varied habitats such as wet grassland, freshwater marshes as well as tall secondary woodland and freshwater reservoir that are near the area. Its addition as a nature area is significant given its rich wet grassland, with two rare plants (Leea angulata and Cayratia trifolia) being sighted. The inclusion of Jalan Gemala will also help secure the sustainability of the existing Kranji Marshes site at Neo Tiew Lane. The Pink-necked Green Pigeons and Mallotus paniculatus, a quick growing shrub that provides food for small birds are some wildlife species that can be found here.
Based on information provided by the Nature Society (Singapore) the Jalan Gemala Nature Area is spread along a length of 4 to 5 kilometres and includes secondary forest, grassland and wetland running along the Kangkar inlet into Kranji Reservoir and is adjacent to Kranji Marsh.
