TH060 Bala Sector, Hala-Bala Wildlife Sanctuary Bala Sector, Hala-Bala Wildlife Sanctuary Province(s): PA Status: EBA / SA: Forest Complex: Narathiwat Wildlife Sanctuary (1996) none Hala-Bala Latitude: Longitude: Area: Altitude Range: Criteria: A1, A3 6º50'N 101º49'E 16,916 ha 100-953 m asl General 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 HalaBala 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. Bird Fauna: Key Features The site supports a rich and diverse lowland evergreen forest avifauna, with a significant Sundaic component. All six globally threatened species recorded at the site are characteristic of the Sundaic region. These include Short-toed Coucal Centropus rectunguis, which is only known from one other site in Thailand (Hala Sector, Hala-Bala Wildlife Sanctuary and Bang Lang National Park, IBA TH059). The site supports at least 63 globally near-threatened species, including two species known from nowhere else in Thailand: Garnet Pitta Pitta granatina and Finsch's Bulbul Alophoixus finschii. The site also supports seven hornbill species, a diversity unparalleled in the rest of the country, comprising Helmeted Hornbill Buceros vigil, Rhinoceros Hornbill B. rhinoceros, Great Hornbill B. bicornis, Plain-pouched Hornbill Aceros subruficollis, Wrinkled Hornbill A. corrugatus, White-crowned Hornbill A. comatus and Black Hornbill Anthracoceros malayanus.

However, nesting has been recorded. The species is a scarce resident at the site. The species was recorded at Tharn To waterfall in 1991 and 1997. The species is an uncommon resident, with a recent record from 1998. Three birds were found roosting together in April 1998. The species is believed to be resident at the site; however, its status is poorly understood. The species is believed to be resident at the site; however, its status is poorly understood. There is a record from April 1997. Biome-restricted Species: The site qualifies under criterion A3 because it supports 111 species restricted to the Sundaic Lowland Forests (Biome 14). See Appendix 3 for details. Other Globally Threatened Species The following list of globally threatened species is a combined list for both sectors of Hala-Bala Wildlife Sanctuary; some of the species on the list may not occur in the Bala sector but only in the Hala sector.
