National Park System, Thailand
Khao Yai National Park, which was the first national park in Thailand, was planned to open as Thailand promulgated the National Park Act in 1961. The first national marine park was established in Khao Sam Roi Yot in 1966. In 1993, the government set up two separate agencies to manage the national land parks and marine parks. According to the National Park Act of Thailand, national parks should have ecological significance and aesthetic value, and the area for unique animals and plants must not be less than 10 km2. Currently, Thailand has 102 national parks (of which 21 are national marine parks). Another 33 land-based national parks and three national marine parks are under construction. In 2002, the newly established Department of National Parks and Wildlife Conservation under the Ministry of Natural Resource and Environment of Thailand took control of the national parks from the Royal Forest Department of the Ministry of Agriculture and Cooperatives of Thailand.
