Site description The IBA comprises of Basset Marsh, a permanent lake located along Road No. 5, about 12 km north of Phnom Penh. The areas surrounding the lake become inundated when the Tonle Sap River floods during the wet season, and thus support extensive marshes. These marshes are surrounded by agricultural land, mainly riceSmall numbers of Spot-billed Pelicans Pelecanus philippensis are regular in the wet season and Darters Anhinga melanogaster are also regular. The IBA is the only known site thus far in Cambodia where River Tern Sterna aurantia has been recorded away from the upper Mekong in the wet season. Grey-headed Fish Eagle Icthyophaga ichthyaetus has also been recorded once and is probably no more than an irregular visitor. Due to its proximity to Phnom Penh and easy access, the IBA has great potential for conservation awareness and education programmes.
