The IBA is centred on Virachey National Park, and borders Laos to the north and Vietnam to the east. The IBA comprises all areas, primarily of evergreen and semi-evergreen forest, within and adjacent to the national park above 150 m asl. The vegetation of the IBA is dominated by dense semi-evergreen forest, interspersed with patches of true evergreen forest, upland savanna, bamboo thickets and occasional patches of mixed deciduous forest. The topography of the IBA is dominated by hills and low mountains, with most areas lying above 400 m asl, and elevations reaching over 1,500 m asl along the border with Laos. The avifauna of the IBA is quite distinct from that of lowland areas to the south and west, which are dominated by deciduous dipterocarp forest. The IBA is one of only two areas in Cambodia known to support Germain's Peacock Pheasant Polyplectron germaini, a restricted-range species. In addition, the IBA supports a number of globally threatened and near-threatened species, including Siamese Fireback Lophura diardi, Red-collared Woodpecker Picus rabieri and Great Hornbill Buceros bicornis. Virachey remains one of the most ornithologically unexplored parts of Cambodia. However, survey work in neighbouring areas of Laos and Vietnam, indicate that higher elevation areas are likely to be of particular importance for globally threatened species such as Black-hooded Laughingthrush Garrulax milleti and Black-crowned Barwing Actinodura sodangorum.
