Site description The IBA is located to the north-east of Stung/Chi Kreng/Kampong Svay Grasslands IBA (KH016), and comprises an area of deciduous dipterocarp forest, interspersed with patches of seasonally inundated grassland, seasonal pools and streams. The IBA is one of the only currently known non-breeding areas for Bengal Florican Houbaropsis bengalensis in Cambodia. The species visits the site when its breeding areas in the inundation zone of Tonle Sap Lake are flooded. In addition, the wetland habitats at the IBA are used as a feeding area by a number of large waterbird species, including Painted Stork Mycteria leucocephala, Woolly-necked Stork Ciconia episcopus, Asian Openbill Anastomus oscitans and Lesser Adjutant Leptoptilos javanicus.

Key Biodiversity Regionally significant species such as Woolly-necked Stork (12 birds recorded in 2002) and Asian Openbill (27 birds recorded in 2002).
