The first nature reserve in China is Dinghu Mountain National Nature Reserve. It was established in 1956 near Zhaoqing City in Guangdong Province mainly to protect evergreen monsoon rain forests of the south subtropical zone. The Reserve lies between east longitude of 112o30′- 112o33′ and north latitude of 23o09′- 23o11′ with an area of 1,133 hectares. The natural forest of the region is one of the special natural forest types in the world, and therefore it is of high science and research value. In 1979, Dinghu Mountain National Nature Reserve was included in the International Man and Biosphere Reserve Network of the UNESCO as a global conservation spot for the research of ecosystem in tropical and subtropical forest.
