The Zhangjiajie National Forest Park is a unique national forest park located in Zhangjiajie City in northern Hunan Province in the People's Republic of China. It is one of several national parks within the Wulingyuan Scenic Area.HistoryIn 1982 it was recognized as China's first national forest park with an area of 4810ha. Zhangjiajie National Forest Park is part of a much larger 397.5km2 Wulingyuan Scenic Area. In 1992, Wulingyuan was officially recognized as a UNESCO World Heritage Site. It was then approved by the Ministry of Land and Resources as Zhangjiajie Sandstone Peak Forest National Geopark (3600km2) in 2001. In 2004, Zhangjiajie Geopark was listed as a UNESCO Global Geopark.The most notable geographic features of the park are the pillar-like formations that are seen throughout the park. Although resembling karst terrain, this area is not underlain by limestones and is not the product of chemical dissolution, which is characteristic of limestone karst. They are the result of many years of physical, rather than chemical, erosion. Much of the weathering which forms these pillars are the result of expanding ice in the winter and the plants which grow on them. The weather is moist year round, and as a result, the foliage is very dense. The weathered material is carried away primarily by streams. These formations are a distinct hallmark of Chinese landscape, and can be found in many ancient Chinese paintings.
