Khao Yai - Research and Facilities
The nomination bibliography lists eight past studies specific to the area, mostly of Khao Yai which has been longer and more closely studied than the other areas. During 2002 - 2003 the DNP with the Wildlife Conservation Society conducted faunal surveys of the sites in preparation for their World Heritage nomination. Studies are ongoing into the unique natural hybridizing between pileated and white-handed gibbons in Khao Yai.

Khao Yai - Conservation
Khao Yai is internationally important for the conservation of threatened and endangered mammals, birds and reptiles. It includes the last substantial area of tropical forest ecosystems in the Thailandian Monsoon Forest. This provides viable habitats for the long-term survival of endangered species such as tigers, elephants, leopards, bantengs, greater adjutants and the migratory spotbilled pelican. No other protected area within the biogeographical region has so long and well marked a continuous topographic, climatic and vegetation gradient. It contains all the major rainforest habitat types of eastern Thailand and some of the region’s largest remaining populations of many tropical forest species, which are coming under pressure elsewhere.

Khao Yai - Description
Khao Yai National Park is Thailand’s second largest, covering 2,168 sq km, encompassing 11 districts and 4 provinces; Sara Buri, Nakhon Ratchasima, Prachin Buri, and Nakhon Nayok. Khao Yai National Park has within its boundaries many thick, flourishing forests, and a plentiful supply of wildlife, such as families of elephants, tigers, gibbons, deer, and wild pigs, etc. This park is the source of five important waterways: the Nakhon Nayok, Prachin Buri , Lamtacong , Lamtaplung, and Hui Muak Lek Rivers. Lands adjacent to the national park are increasingly developed into luxury hotels and golf courses for weekend visitors from Bangkok. Such development limits wildlife corridors and permanently reduces future conservation and land acquisition ability.
Khao Yai National Park was Thailand’s first National Park, and was established on September 18, 1962. It was originally known as 'The National Park Heritage of Asian Group Countries'. In 1984 the park was made an ASEAN Heritage Site, and on July 14 2005 the park was inscribed as a UNESCO World Heritage site under the name Dong Phaya Yen–Khao Yai Forest Complex together with other parks in the Dong Phaya Yen mountains.
