How it came to be

The Dong Phayayen–Khao Yai Forest Complex runs 230 km across northeast Thailand, from Ta Phraya National Park on the Cambodian border west to Khao Yai National Park. It joins four national parks and one wildlife sanctuary.

Khao Yai at its heart became Thailand's first national park on 18 September 1962, with Boonsong Lekagul playing a major part. The forest holds more than 800 animal species, including 112 mammals and 392 birds, and it is the only known place where the ranges of two gibbon species overlap and the two interbreed.

The complex was inscribed in 2005. Illegal logging of Siamese rosewood and road widening later led the World Heritage Committee to warn of a possible listing as in danger. In March 2017 a breeding population of Indochinese tigers was confirmed inside the forest.
