Site description The IBA is located inside Dong Khanthung proposed protected area, in southern Lao P.D.R. The topography of the IBA is dominated by a flat plain, between 90 and 120 m asl, bordered to the south by the Xe Lamphao, which forms the international border with Cambodia, and to the west by a ridge of hills, between 200 and 500 m asl, which form the international border with Thailand. Within the IBA, there are many permanent and seasonal pools, streams and rivers. The vegetation of the IBA comprises a mosaic of dry dipterocarp forest and semi-evergreen forest, with taller forest being found mainly along watercourses (Round 1998). To the south, the IBA is contiguous with Chhep IBA (KH016) in Cambodia, which supports a similar mosaic of habitats. The mosaic of forests and wetlands within the IBA is important for the conservation of a suite of large waterbirds, including Giant Ibis Thaumatibis gigantea, Black-necked Stork Ephippiorhynchus asiaticus, Woolly-necked Stork Ciconia episcopus and Lesser Adjutant Leptoptilos javanicus, of which the latter two species are confirmed to breed (Round 1998). Sarus Crane Grus antigone has also been recorded at the IBA but the population is not believed to be significant and the species is believed to be on the verge of extirpation (Round 1998). White-shouldered Ibis Pseudibis davisoni has been provisionally recorded, and, if it was confirmed to regularly occur in significant numbers, the conservation importance of the IBA would be markedly increased. The riverine habitats within the IBA are important for a suite of key bird species, including White-winged Duck Cairina scutulata, Masked Finfoot Heliopais personata, Lesser Fish Eagle Ichthyophaga humilis and Grey-headed Fish Eagle I. ichthyaetus. While there may not be sufficient suitable habitat within the IBA to support viable populations of these species in the long term, the IBA forms part of a network of sites in southern Lao P.D.R., northern Cambodia and eastern Thailand that may be able to. Small numbers of White-rumped Vulture Gyps bengalensis and Red-headed Vulture Sarcogyps calvus have been recorded at the IBA, although, again, these are probably part of larger populations distributed across a wider area. Other globally threatened and near-threatened bird species found at the IBA include Green Peafowl Pavo muticus, White-rumped Falcon Polihierax insignis and Asian Golden Weaver Ploceus hypoxanthus (Round 1998). In addition, the IBA is the only known wintering site for Manchurian Reed Warbler Acrocephalus tangorum in Lao P.D.R. (Duckworth et al. 1999), although this species may occur widely elsewhere, as there has been little ornithological study at potentially suitable localities. Furthermore, the IBA is one of only two sites in Lao P.D.R. known to support Moustached Hawk Cuckoo Cuculus vagans (Duckworth et al. 1999). Finally the IBA supports Pileated Gibbon Hylobates pileatus (Duckworth et al. 1999), and one of only two confirmed populations of Eld's Deer Cervus eldii in Lao P.D.R. (Duckworth et al. 1999, Vongkhamheng and Phirasack 2002), although, if this population is still extant, it is under intense threat (Round 1998).
