Stretching over more than 600,000 ha along the Myanmar border, the sanctuaries, which are relatively intact, contain examples of almost all the forest types of continental South-East Asia. They are home to a very diverse array of animals, including 77% of the large mammals (especially elephants and tigers), 50% of the large birds and 33% of the land vertebrates to be found in this region.
Thung Yai-Huai Kha Khaeng Wildlife Sanctuary World Heritage property lies in Uthai Thani, Tak, and Kanchanaburi provinces in the west of Thailand, alongside the border with Myanmar. The property combines two contiguous sanctuaries, Thung Yai Naresuan and Huai Kha Khang, separately established as sanctuaries in 1972 and 1974, respectively. Thung Yai-Huai Kha Khaeng Wildlife Sanctuary encompasses two important river systems, the Upper Khwae Yai and the Huai Khakhaeng. The property, encompassing 622,200 hectares, is the largest conservation area in Mainland Southeast Asia and is one of Thailand’s least accessible and least disturbed forest areas.
