Site description The IBA comprises Mae Fang National Park, which lies within the Pee Pun Nam range, along the international border with Myanmar. The topography of the site is dominated by high mountains, including Doi Ang Khang in the south and Doi Pha Hom Pok (Thailand's second highest peak) in the north. The most extensive remnant tracts of hill evergreen forest are above 1,700 m asl on Doi Pha Hom Pok, covering c.16,000 ha, while c.6,800 ha of hill evergreen forest remain in the Doi Ang Khang area. Forest at mid-elevations, between 1,000-1,500 m asl, has been extensively cleared for shifting cultivation, some of which has reverted to grassland; over 9,900 ha is estimated to have been encroached upon by shifting cultivation. In addition to evergreen forest types at higher elevations, some mixed deciduous forest and deciduous dipterocarp forest occur at lower elevations.
