Pudacuo National Park is set in one of the most biodiverse regions of the world. While the region comprises less than 1% of China's land area, it contains more than 20 % of the country's plant species, about one-third of its mammal and bird species and almost 100 endangered species including fish and rare orchids. Among the bird species recorded here is the endanagered black-necked crane. The region is famous for crystal lakes and breathtaking scenery. A highlight of the park is Shudu Lake, a calm lake surrounded by pastures and forest flowers. It is set at 3,705 metres above sea level and is one of the largest lakes in Diqing Prefecture. Every spring and summer herds of yak and goat are found grazing alongside its waters.
