Site description The IBA is an area of seasonally inundated grassland, dominated by Wild Rice Oryza rufipogon, located within the inundation zone of Tonle Sap Lake, along the border between Kampong Thom and Kampong Chhnang Provinces. The seasonally inundated grassland is surrounded by dense tall scrub and swamp forest and there are numerous seasonal pools and lakes. The southern part of the IBA is situated within Tonle Sap Multiple Use Area, designated under the 1993 Royal Decree on Protected Areas, and Tonle Sap Biosphere Reserve. During the dry season, the IBA supports a breeding population of Bengal Florican Houbaropsis bengalensis. Also during the dry season, the IBA is visited by a number of non-breeding large waterbirds, including Painted Stork Mycteria leucocephala, Asian Openbill Anastomus oscitans, Lesser Adjutant Leptoptilos javanicus and Greater Adjutant L. dubius. In addition, White-shouldered Ibis Pseudibis davisoni has been recorded at the IBA, although the precise status of this species is unclear.

Key Biodiversity Other regionally significant species occur at the site such as Grey Heron, Great Egret, Little Cormorant, Brahminy Kite and Asian Openbill.

Non-bird biodiversity: Long-tailed Macaque (Macaca fascicularis), Silvered Langur (Semnopithecus cristatus).

Medium - based upon reliable but incomplete / partially representative data

Agriculture and aquaculture annual & perennial non-timber crops - small-holder farming happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
Biological resource use fishing & harvesting aquatic resources - unintentional effects: subsistence/small scale happening now some of area/population (10-49%) slow but significant deterioration medium
Biological resource use hunting & collecting terrestrial animals - intentional use (species being assessed is the target) happening now majority/most of area/population (50-90%) moderate to rapid deterioration high

Most of site (50-90%) covered (including the most critical parts for important bird species)  No management planning has taken place  Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity  low
