1.1 Unique Biological Views
The Ningde Global Geopark is noted for its superior natural conditions and excellent biological environment. It boasts old banyan trees growing in the utmost northern latitude of the globe, natural mangroves and largest area of Chinese sweet gum in the south of Yangzi River. Furthermore, it is also well known for its flourishing cryptomeria with a history of one thousand years, water pine, a kind of relics plant in quaternary glacial epoch, rare tree species-Maire Yew and ginkgo, luxuriant tropical evergreen broadleaf forest and rare animals such as mandarin duck and monkeys etc. All these constitute an unique biological view. What is worth mentioning in the park are its other special biological scenic spots such as Putaogou (grape ravine) in Xita village,Muyun Town of She ethnic group, Tianhu grassland on Dayu Mountain, bird island and tea garden.
