A national-class nature reserve and the best-preserved of green lands at the same latitude on earth, the nature reserve has a forest coverage of 97.3%. Mountain Huanggang, the main peak, towers 2,158 meters above sea level. It is referred to as the Roof of East China. The 20,000-hectare primitive forest in the surroundings abounds in fauna and flora resources. The forest is called a window on the living things in the world, a paradise of birds, a kingdom of snakes, and a world of insects by people in the scientific community. The nature reserve became a member of UNESCO's Men and the Biosphere, and on December 1, 1999, was included in the list of World Natural and Cultural Heritages.
