Site description (2003 baseline)
The IBA is situated in southern Mondulkiri and Kratie provinces, and comprises an extensive mosaic of evergreen and semi-evergreen forest habitats, from Snoul Wildlife Sanctuary in the south-west to Phnom Nam Lyr Wildlife Sanctuary in the north-east. Most of the intervening areas between the two wildlife sanctuaries are situated within a forest concession under the management of Samling International. However, this area is also managed as a biodiversity conservation area within the concession system. The vegetation of the IBA is characterised by evergreen and semi-evergreen forest on hills, grading into mixed deciduous and deciduous dipterocarp forest to the north-west. The dominant vegetation type is semi-evergreen forest, which varies greatly in structure and composition, from apparently evergreen-dominated stands with a high density of lianas, palms and rattans, to tracts with a more open understorey. Within the predominantly level lowland Snoul Wildlife Sanctuary there are numerous grassy clearings with pools within the evergreen forest. To the south-east, the IBA is contiguous with areas of natural habitat in Vietnam, a significant proportion of which is included within Bu Gia Map Nature Reserve.The results of recent surveys indicate that the IBA supports all three restricted-range species found in the Cambodia-South Vietnamese Lowlands Endemic Bird Area: Orange-necked Partridge Arborophila davidi, Germain's Peacock Pheasant Polyplectron germaini and Grey-faced Tit Babbler Macronous kelleyi. The IBA also supports a number of other globally threatened and near-threatened species, including Green Peafowl Pavo muticus, White-winged Duck Cairina scutulata, Great Hornbill Buceros bicornis and Siamese Fireback Lophura diardi. Finally, higher elevation areas within Phnom Nam Lyr Wildlife Sanctuary (up to 1,070 m asl) support some elements of a montane avifauna, which, although little studied, appears to have some similarities with that of the lower slopes of the Da Lat plateau to the east. For example, these areas support Black-throated Tit Aegithalos concinnus, White-cheeked Laughingthrush Garrulax vassali and Black-chinned Yuhina Yuhina nigrimenta.
