Site description The IBA comprises the Hala sector of Hala-Bala Wildlife Sanctuary (c.26,400 ha) and the contiguous Bang Lang National Park (c. 26,100 ha). The site is situated in the San Kara Khiri mountain range, and is contiguous with Belum Forest Reserve in Malaysia. Hala-Bala Wildlife Sanctuary consists of two non-adjacent sectors: the Bala sector in Narathiwat province; and the Hala sector in Yala province. Due to the wet, aseasonal climate, the site supports wet evergreen forest at elevations below 600 m asl, with hill evergreen forest and lower montane evergreen forest at higher elevations.
