Site description The IBA comprises the estuary of the Taek Sap River, which flows into the Gulf of Thailand to the east of Ream National Park. At the mouth of the estuary is situated a large island, called Koh Thmei. The vegetation of the IBA is dominated by intertidal mudflats and coastal mangrove, with some stands of Nypa and areas of degraded Melaleuca forest on the landward side of the mangrove. The IBA is a non-breeding site for a number of large waterbirds, including Lesser Adjutant Leptoptilos javanicus, Painted Stork Mycteria leucocephala and Spot-billed Pelican Pelecanus philippensis. Most significantly, the IBA is the most important known non-breeding site in Cambodia for Milky Stork Mycteria cinerea, which breeds at Prek Toal IBA, and most probably at an as yet undiscovered location in south-west Cambodia, quite possibly nearby (perhaps even within) this IBA.

Key Biodiversity Other regionally sinificant bird species: Woolly-necked Stork.

Non-bird biodiversity: Indo-Pacific Humpback Dolphin (Sousa chinensis) occurs around Koh Thmei and is data deficient.Long-tailed Macaque (Macaca fascicularis)
