Site description The IBA comprises Thung Yai-Naresuan Wildlife Sanctuary, one of the largest protected areas in mainland South-east Asia, which lies along the international border with Myanmar. The site is situated within the Western Forest Complex, and adjoins Umphang Wildlife Sanctuary (IBA TH024) to the north, Huai Kha Kaeng Wildlife Sanctuary (IBA TH026) to the east, and Khao Laem (IBA TH027), Lam Khlong Ngu and Sri Nakarind (IBA TH028) National Parks to the south. The topography of the site is generally hilly or mountainous, with numerous permanent rivers and streams dividing the site into valleys and ridges. Notably, the site also includes a large central grassland plain, as well as Doi Khao Yai, one of the highest mountains in western Thailand. The principal vegetation types are hill evergreen forest (c.54,900 ha), dry evergreen forest (c.112,900 ha), mixed deciduous forest (c.164,100 ha), deciduous dipterocarp forest (c.3,600 ha), savanna woodland (c.9,900 ha), grassland (c.3,900 ha), a small area of swamp forest, and some areas of shifting cultivation (c.15,400 ha). Hill evergreen forest occupies the higher elevations, while the more level areas at moderate elevations generally support semi-evergreen forest, mixed deciduous forest and bamboo. In 1991, Thung Yai-Naresuan, together with the adjacent Huai Kha Kaeng Wildlife Sanctuary (IBA TH026), was designated as a World Heritage Site.
