Site description The IBA comprises the Bala sector of Hala-Bala Wildlife Sanctuary, which is located at the southernmost tip of peninsular Thailand, on the international border with Malaysia. To the west of the site is the Hala sector of Hala-Bala Wildlife Sanctuary (within IBA TH059), from which the site is separated by a major highway, which forms an effective barrier to the dispersal of some species. The topography of the site is more predominantly lowland than that of the Hala sector. Due to the wet, aseasonal climate, the site supports wet evergreen forest.
