BirdLife Indochina Programme (BirdLife Direct Action Programme)

Site description This IBA comprises a contiguous area of open deciduous dipterocarp forest extending from the western parts of Lomphat Wildlife Sanctuary, to the north and west, as far as the confluence of the Sesan and Srepok Rivers. The Srepok River and its associated riverine vegetation is integral to the IBA, and both banks of the river are included within the IBA. The section of the Srepok included in the IBA is c.200 m wide, with a rocky substrate with associated shrubs. The vegetation of the IBA is dominated by , although mixed deciduous forest and, less commonly, semi-evergreen forest, also occur. Seasonal streams, often flanked by gallery forest, are found throughout the IBA, and there are numerous pools, mostly seasonal. These pools are typically less than 100 m in diameter but are often associated with large seasonal meadows, which can be several hundred metres in length. The IBA supports one of the most intact remaining examples of the bird community of the dry forests of central Indochina. The seasonal meadows are important nesting areas for Sarus Crane Grus antigone, while the pools are important for a number of large waterbirds, including Giant Ibis Pseudibis gigantea and Lesser Adjutant Leptoptilos javanicus. Also, the IBA includes Trapeang Rokar, an area of wetlands between the Srepok and Sesan Rivers, where White-shouldered Ibis Pseudibis davisoni was observed in 1998. The Srepok River supports a number of riverine species, including Masked Finfoot Heliopais personata and the recently described Mekong Wagtail Motacilla samveasnae. The relative abundance of large ungulates means that the IBA has greater potential to support viable populations of White-rumped, Long-billed and Red-headed Vultures Gyps bengalensis, G. indicus and Sarcogyps calvus than most other areas in mainland South-east Asia.
