Site description The IBA is centred on the Stung Sen Core Area of Tonle Sap Biosphere Reserve. The IBA is located at the south-eastern end of Tonle Sap Lake, to the north of the point where the Tonle Sap River leaves the lake. The vegetation of the IBA is characterized by botanically unique gallery forest along rivers, dominated by Barringtonia acutangula and Diospyros cambodiana. Although disturbed, this habitat is the most species-rich tall forest around Tonle Sap Lake. The IBA supports an important breeding colony of Darter Anhinga melanogaster, as well as a significant breeding concentration of Grey-headed Fish Eagle (Ichthyophaga ichthyaetus).
