Site description The IBA comprises the catchment of the upper Stung Sen river. The vegetation of the IBA is dominated by open deciduous dipterocarp forest (grading into mixed deciduous and semi-evergreen forest in the west), permanent and seasonal wetlands and grasslands.Much of the IBA is a floodplain and in the wet season, is inundated, while in the dry season, water is restricted to a few permanent watercourses (the Stung Sen river and its larger tributaries) and pools. Along these watercourses, semi-evergreen forest and thick bamboo forest are distributed. Much of the IBA is located within Kulen Promtep Wildlife Sanctuary. The IBA supports one of the few breeding colonies of Darter Anhinga melanogaster remaining outside of the Tonle Sap Lake floodplain. In addition, the IBA is an important breeding site for Sarus Crane Grus antigone and Lesser Adjutant Leptoptilos javanicus. Furthermore, a number of other globally threatened and near-threatened species have been recorded at the site, including Giant Ibis (Pseudibis gigantea), White-shouldered Ibis (Pseudibis davisoni), Greater Adjutant (Leptoptilos dubius), Black-necked Stork (Ephippiorhynchus asiaticus) and Grey-headed Fish Eagle (Ichthyophaga ichthyaetus).
