TH011 Doi Phu Kha National Park Doi Phu Kha National Park Province(s): PA Status: EBA / SA: Forest Complex: Nan National Park (1988) none Doi Phu Kha-Mae Yom Criteria: A1, A3 Latitude: Longitude: Area: Altitude Range: 19º36'N 100º54'E 170,400 ha 300-1,980 m asl General Description The IBA comprises Doi Phu Kha National Park, which adjoins Mae Jarim proposed national park (IBA TH010) to the south. The topography of the site comprises both steep mountains and gently rolling hills, and the site contains the headwaters of the Lam Nam Nan river. Mixed deciduous forest covers c.90% of the site, although, above 1,000 m asl, small pockets of hill evergreen forest are found. In addition, there are small amounts of dry evergreen forest (c.700 ha) and deciduous dipterocarp forest (c.900 ha) at the site. Notably, the site supports the largest palm forest in Thailand, covering c.428 ha. Some areas of forest have been converted to agriculture, with c.10,400 ha of the site comprising active and fallow shifting cultivation. Bird Fauna: Key Features Doi Phu Kha National Park is the most important known site in Thailand for the conservation of the globally threatened Beautiful Nuthatch Sitta formosa. This montane forest species is very rare in Thailand, and is otherwise known only from an historical record at Mae Fang National Park (IBA TH005). The site also supports significant populations of other montane forest residents that are known from few other sites in Thailand, including Blackthroated Tit Aegithalos concinnus, Red-faced Liocichla Liocichla phoenicea and Whiskered Yuhina Yuhina flavicollis. In addition, the site supports Jerdon's Bushchat Saxicola jerdoni, a species characteristic of the IndoGangetic Plains (Biome 12). Species Beautiful Nuthatch Sitta formosa Season R Global Threat Status VU IBA Criteria Notes A1, A3 The species was first recorded at c.1,940 m asl in March 2003. Subsequently, nine birds were recorded at 1,750 m asl during April 2003, when adults were seen feeding fledged young. Biome-restricted Species: The site qualifies under criterion A3 because it supports 37 species restricted to the Sino-Himalayan Subtropical Forests (Biome 08), six species restricted to the Indo-Malayan Tropical Dry Zone (Biome 11), and one species restricted to the Indo-Gangetic Plains (Biome 12).
