Site description The IBA comprises the stretch of the Sekong River from the international border with Laos to its confluence with Mekong River. Along this stretch of the river, there are many different habitats, many of which can be catagorised as channel mosaics of rock and sand islands with riverine scrub. There are no stretches dominated by extensive sandbars, and significant stretches are slow-moving and relatively featureless. For much of its length, the Sekong River is fringed by a belt of gallery forest, about 100 m wide, which is significantly taller than the adjacent deciduous dipterocarp forest, and contains a high proportion of broadleaf evergreen trees. However this has been degraded or cleared for cultivation in many areas.The IBA supports a suite of bird species restricted to wide, lowland rivers, including River Lapwing Vanellus duvaucelii, Small Pratincole Glareola lactea, Great Thick-knee Esacus recurvirostris and River Tern Sterna aurantia. In addition, the IBA supports Mekong Wagtail Motacilla samveasnae, a recently described species, which is thought to be endemic to the Mekong River and its major tributaries. Furthermore, at certain times of the year, the IBA may be important for a number of large waterbirds, including Giant Ibis Pseudibis gigantea.
