Pasir Ris is Malay for 'beach bolt-rope', implying a narrow beach. The park is open 24 hrs, and there is no entrance fee. Bicycle rental is available at the park. Visitors can spend half a day travelling around wooden walkways, which reduce damage to the substrate and allow you a close but comfortable look at the forest without getting you muddy.
The bulk of the mangrove area is a mature community with textbook features, especially the diverse number of tree species, unlike the managed mangrove forests in Malaysia where only a few commercially valuable species are found. The mangroves consist of the more common species such as trees of Avicennia alba, A. officinalis and A. rumphiana, Bruguiera cylindrica, B. gymnorhiza, Ceriops tagal, Rhizophora apiculata, R. mucronata, Scyphiphora hydrophyllacea, the ferns Acrostichum aureum, A. speciosum, and the shrubs Acanthus ebracteatus, and A. ilicifolius amongst others. (for a full list). It also has rarer species such Aegiceras corniculatum, Bruguiera parviflora and Rhizophora stylosa, which are all considered endangered locally.
You can observe mudskippers grazing, and displaying their territorial and mating behaviour in the canals that drain through the park during low tide. Fiddler crabs can be seen easily at the sandy areas at the eastern-most edge.
This mangrove patch is under constant threat of having the salinity of the soil flushed out. The more aggressive freshwater species will invade the patch once the salinity declines so the tidal inundation is imperative for its maintenance. Most mangrove species can cope with freshwater but cannot compete with freshwater species in a primarily freshwater environment.
