The Prek Toal Ramsar Site includes some of the most pristine floodplains in the Tonle Sap Biosphere Reserve in Cambodia. During the dry seasons, the Site is dry and covered mostly by freshwater swamp forests, but it floods annually, with the water depth reaching up to eight metres. Prek Toal is at the north-west upstream end of Tonle Sap Lake and the rise and fall of the lake’s waters play a vital role in maintaining its biological wealth. The forests trap large quantities of sediment, and the nutrients deposited stimulate the growth of plants and fish which support the high numbers of waterbirds and other wildlife at the Site. Prek Toal includes a range of habitats for a great diversity of globally threatened species such as the critically endangered river terrapin (Batagur baska), Siamese crocodile (Crocodylus siamensis), giant barb (Catlocarpio siamensis), and Mekong giant catfish (Pangasianodon gigas). The high concentration and diversity of nesting waterbirds (with over 20,000 counted regularly since 2001), including many globally threatened species such as the endangered greater adjutant (Leptoptilos dubius) and masked finfoot (Heliopais personatus), make the area unique in the biogeographic region. The local communities live in floating houses and depend on fishing and aquaculture for their livelihoods.
