Site description The IBA comprises one of the largest remnant tracts of contiguous semi-natural grassland within the Tonle Sap inundation zone. . The vegetation of the IBA is characterised by a mosaic of tall and short grass swards, mixed with some patchy, dense scrub, limited deepwater rice fields and small, scattered wetlands. Wet season rice is cultivated along the IBA's northern fringe adjacent to RN6. The seasonally inundated grassland supports the highest densities of breeding Bengal Floricans Houbaropsis bengalensis found in Cambodia to date, and the IBA supports a highly significant population of this species. The small pools are used as feeding areas by a number of large waterbirds dispersing from the Tonle Sap breeding colonies, including Painted Stork Mycteria leucocephala and Lesser Adjutant Leptoptilos javanicus. The IBA also supports a substantial wintering population of Manchurian Reed Warbler Acrocephalus tangorum, as well as small numbers of wintering Greater Spotted Eagle Aquila clanga.

Agriculture and aquaculture annual & perennial non-timber crops - agro-industry farming happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
Biological resource use hunting & collecting terrestrial animals - unintentional effects (species is not the target) happening now some of area/population (10-49%) no or imperceptible deterioration low
