Khao Yai National Park

Khao Yai National Park was established on 18 September 1962, declared by royal proclamation in the Government Gazette as the first national park of Thailand. A major role in its establishment was played by Boonsong Lekagul. It was named after the defunct tambon, Khao Yai. In 1984, Khao Yai National Park was made an ASEAN Heritage Park, and on 14 July 2005, it was proclaimed a UNESCO World Heritage Site under the name Dong Phayayen–Khao Yai Forest Complex together with other national parks in the same range and in the Dong Phaya Yen Mountains further north. As the lands adjacent to the national park are becoming increasingly developed into luxury hotels and golf courses, acquiring land for future wildlife conservation efforts is becoming problematic. Homes and residential villas have been built illegally within the limits of the protected area of the forest. Illegal logging is also a problem in the area. ==Geography==
