Khao Yai Study Area

Namtok Than Rattana Established in 1960 and covering 2172km2, Khao Yai National Park is the oldest and one of the largest parks in Thailand. The park is known for its biotic diversity, especially its vertebrates and vegetation. Much of the park is covered by tropical and submontane broad-leaved evergreen forests. The rich biota reflects partly the park's altitudinal diversity (60-1350m). Much of Khao Yai National Park consists of a large sandstone plateau dissected by numerous streams. The park contains many streams and waterfalls (e.g., Heo Sawat, Heo Narok), some with unique and currently undescribed species. Surveys of aquatic Diptera, Plecoptera, and other aquatic insects were conducted at more than 20 streams, including the following:
