Site description The IBA comprises an extensive area of wetlands between the Mekong and Bassac Rivers. The vegetation of the IBA is dominated by seasonally inundated shrub and savanna swamp, which is surrounded by agricultural land. During the wet season, the IBA is inundated, and is characterised by large areas of deep, open water, with substantial areas of emergent, floating and submerged aquatic vegetation. The IBA supports large numbers of commoner waterbirds, as well as small numbers of Darter Anhinga melanogaster, Spot-billed Pelican Pelecanus philippensis and Asian Golden Weaver Ploceus hypoxanthus. In addition, the IBA regularly supports more than 1% of the Asian biogeographic population of Whiskered Tern (Chlidonias hybridus).
