Site description The IBA is primarily comprised of the catchment of the Srepok River upstream of Lomphat town, excluding a few peripheral areas that are heavily degraded. The topography of the IBA is relatively flat, although there are a number of low hills, most notably those around Phnom Yang Ke. The vegetation of the IBA is characterised by a habitat mosaic dominated by deciduous dipterocarp forest, with smaller areas of semi-evergreen forest and mixed deciduous forest. In addition, the IBA contains numerous wetlands. In addition to the Srepok River, its permanent tributaries and associated oxbow lakes, there are numerous seasonal streams, some of which retain pools of water during the dry season. There are also numerous pools and seasonally wet meadows, which vary in size from a few metres to a few hundreds of metres in width. The north-western part of the IBA is included within Lomphat Wildlife Sanctuary, while the southern part is included within a recently decreed Forest Reserve for Conservation of Genetic and Wildlife Resources. The IBA supports one of the most intact remaining examples of the bird community of the dry forests of central Indochina. 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. In addition, the Srepok River is one of the few sites in Cambodia known to support Masked Finfoot Heliopais personata. Furthermore, there is a single record of White-winged Duck Cairina scutulata from the IBA, and the presence of significant areas of suitable habitat indicate that the IBA may support a significant population of this species. There is also a single record of White-shouldered Ibis Pseudibis davisoni but the precise status of this species at the IBA is not known. Finally, there is a single record of Pale-capped Pigeon Columba punicea from along the Dak Dam stream, which forms the international border with Vietnam, although it is unclear exactly which stretch this record is from, and it may even be from within Snoul/Keo Sema/O Reang IBA (KH027). As with White-shouldered Ibis, the precise status of this species at the IBA is not known.
