Site description The IBA is located to the south of Kampong Thom town, within the inundation zone of Tonle Sap Lake. The IBA comprises and one of the largest remnant tracts of seasonally inundated grassland within the Tonle Sap floodplain, variably influenced on its eastern and northern fringes by deepwater rice. This habitat is mixed with scattered, but often extensive, areas of dense scrub, lotus swamps, sedge beds, and, in the dry season, numerous small to medium-sized ponds. At the height of the wet season (August-October), the whole IBA is inundated. Parts of the IBA lie within Tonle Sap Multiple Use Area, designated under the 1993 Royal Decree on Protected Areas, and Tonle Sap Biosphere Reserve.The IBA is a very important breeding site for Bengal Florican Houbaropsis bengalensis during the dry season (December to May). In the wet season (May to July), a number of non-breeding waterbirds visit the site, including adjutants Leptoptilos spp., Painted Stork Mycteria leucocephala and Asian Openbill Anastomus oscitans. In addition, the IBA supports a substantial wintering population of Manchurian Reed Warbler Acrocephalus tangorum, as well as small numbers of wintering Greater Spotted and Imperial Eagles Aquila clanga and A. heliaca. In addition, the largest flock of White-shouldered Ibis Pseudibis davisoni recorded in Cambodia in recent decades was observed here in 1999.
