The Heilongjiang Qixing River National Nature Reserve is located in Northeast China and is representative of the inland freshwater marsh type in Northeast Asia. The site is recognized as one of the best preserved natural wetland areas in China, and supports a diversity of wetland plants and animals, including many waterbirds that also breed there. The large-scale reed marshes in this Ramsar Site are one of the most important in the Sanjiang Plain (Northeastern China Region) and have the remarkable ability of water storage and flood control. This site supports 29 threatened species of which 3 are mammals and 26 are birds such as Siberian Crane, Oriental Stork, Red-crowned Crane, Scaly-sided Merganser and Baer's Pochard. The diverse wetland types at this site provide important habitats for many species, including 388 plant species, 201 birds (including 80 waterbirds), 35 mammals, 10 amphibians and reptiles, and 18 fish species. More that 1% of the population of nine waterbirds species is present at the site. The Heilongjiang Qixing River National Nature Reserve is an ideal base for scientific research, education and popularization of wetland conservation. The rich biodiversity can provide germplasm resource for the development of agriculture, forestry and aquaculture in the region. The Master Plan for Qixing River Nature Reserve and Management Methods for Qixing River Nature Reserve have been developed and been implemented.
