Mount Sanqing () is a renowned Taoist sacred mountain located north of Yushan County in Jiangxi Province. Sanqing means the "Three Pure Ones" in Chinese as Mount Sanqing is made up of three main summits: Yujing, Yushui, and Yuhua, representing the Taoist trinity. A Chinese phrase “三峰峻拔、如三清列坐其巅” (“Three steep peaks, like the Three Pure Ones sit the summits”) explains why it was named San Qing. Amongst the three hills, the Yujing hill (1817 meters above sea level) is the highest. Mount Sanqing is the highest of the Huaiyu Mountains and is known for its outstanding scenery and unique geological formations. The area became a National Geopark in 2005, and a UNESCO World Heritage Site in 2008. It is a famous tourist destination as well as a refuge for animals and plants. The national park contains more than 2300 species of plants and 400 species of vertebrates. The total area of Mount Sanqing is 229 km². Geological History and Hydrology Mount Sanqing is a granite mountain that forms a part of a crustal suture zone dating back to the Neoproterozoic Era, roughly 850 million years ago. However, the granite making up much of the mountain peaks dates from the Mesozoic. Faulting, weathering and erosion have shaped the mountains into intricate landforms. On Mount Sanqing, there are more than 23 gorges with more than 500 meters of elevation. The abundant yearly rainfall in the region allows for many waterfalls (some of which are over 60 meters in height), pools, and springs in the region. Biodiversity Located in a humid subtropical climate zone, Mount Sanqing and the surrounding national park is relatively biodiverse. Over 2300 plant and 400 vertebrate species have been described within the park boundaries, some of which are threatened with extinction. Flora There are many vegetation types in Mount Sanqing, including evergreen broad-leaved forests, warm temperate coniferous forests, warm temperate needle and broad-leaved mixed forests, bamboo forests, temperate needle and broad-leaved mixed forests, evergreen and deciduous broad-leaved mixed forests, coppice forests, and mountain top meadow coppice forests. This, coupled with the isolated topography of the region and its status as an Ice-Age refugium, has allowed high rates of floral biodiversity and endemism. Mount Sanqing protects many conifer species in particular, including rare varieties of Pseudotsuga sinensis gaussenii and Tsuga spp. 19 of the plants found in the park were listed on the IUCN Red List as of 2003.
