Site description The IBA is comprised of the estuary of the Sre Ambel River, and the associated wetland habitats. The vegetation of the IBA comprises an area of intertidal mudflats and mangrove, backed by an extensive area of Melaleuca swamp, which contains numerous small wetlands. Although the IBA has received little recent ornithological study, a range of large waterbirds in small numbers, including Milky Stork Mycteria cinerea, Painted Stork Mycteria leucocephala, Woolly-necked Stork Ciconia episcopus, Black-necked Stork Ephippiorhynchus asiaticus and Lesser Adjutant Leptoptilos javanicus. Perhaps most notably, the IBA supports a small non-breeding population of Sarus Crane Grus antigone. In addition, there are historical records of both Giant and White-shouldered Ibises Pseudibis gigantea and P. davisoni from what is believed to be the general vicinity of the IBA, although there are no recent records. The IBA is included within Dong Peng Multiple Use Area, designated under the 1993 Royal Decree on Protected Areas.

Key Biodiversity The site holds the Globally threatened species such as Sarus Crane (Grus antigone), Milky Stork (Mycteria cinerea), Painted Stork (Myctetria leucocephala) and Lesser Adjutant (Leptoptilos javanicus). During the survey on 29-30 May 2002, 23 Woolly-necked Storks were observed feeding where Prang villagers reported to have Sarus Cranes from 4-10 birds coming every year to feed in cultivated area (UTM: 0357181-1229107) located in the northeast of Prang village about 500m. Sarus Cranes reportedly present in this area from February to early May.

Non-bird biodiversity: Long-tailed Macaque (Macaca fascicularis).River Terrapin (Batagur baska).
