Pudacuo National Park in China's Southwest Yunnan Province is located in one of the most bio-diverse regions in the world. While the region comprises only 0.7 percent of China's land area, it contains more than 20 percent of the countrys plant species, about one-third of its mammal and bird species, and almost 100 endangered species. Pudacuo qualifies as a natural wonderland according to any standard. It contains endemic species of fish found no where else in the world, rare and beautiful orchids, black-necked cranes, and taxus yunnanensis, a yew whose extracts are indispensable to the creation of many cancer-treating drugs. Nestled in the mountains of Southwest China, the park is an integral part of the Three Parallel Rivers Scenic Area, a UNESCO World Heritage Site and one of Chinas most popular tourist destinations.
