Site description The IBA comprises Kaeng Krachan National Park, the largest national park in Thailand. The site is located in the Tenasserim range, which forms the international border between Thailand and Myanmar. The topography of much of the site is hilly or mountainous. The vegetation at the site is dominated by semi-evergreen forest, with wetter lowland evergreen forest occurring in the interior of the park, and hill evergreen forest being found above 1,000 m asl. Several plant species with more southerly distributions occur at the site, for example Orania sylvicola, Diptercarpus dyeri and Archidendron jaringa. The lower reaches of two major streams have been dammed to form Kaeng Krachan reservoir, which covers c.4,500 ha. Parts of the site have been logged.
