Recent data analysis has confirmed that Prek Toal is the most important breeding site for waterbirds in and around the Tonle Sap Biosphere Reserve (TSBR), while also highlighting several additional sites that are important for waterbirds. It also suggests that Prek Toal is not only a breeding site, but that significant numbers of Spot-billed Pelican, Oriental Darter and Lesser Adjutant stay in the area the whole year round.
The data suggest that Boeung Tonle Chhmar is an important feeding site in the dry season and early wet season for most large waterbirds that breed colonially in the TSBR; this was also suggested in the 2008 review but has been reinforced by the new data. The Stung Sen Core Area seemed to be visited by waterbirds more in the wet season than in the dry season. At present the data do not indicate any exceptional value of this site for large waterbirds compared to other areas of the inner floodplain, with the possible exception of Spot-billed Pelicans.
Dey Roneath continues to be of interest as a potential breeding colony but lacks year-round monitoring data. Veal Srongai was seen to be important for many of the large waterbirds that breed colonially in the TSBR. The nearby area of Krous Kraom, which was once grassland but is increasingly dominated by intensive agriculture, continues to be much used by many species considered in this report. The Integrated Farming & Biodiversity Areas (IFBAs), including the Stoung-Chikraeng IFBA group, contain a wide diversity of species, including Black-necked Stork and Woolly-necked Stork.
