Heilongjiang Nanweng River National Nature Reserve is located in the Great Xingan Mountains Area, Songling District, in Northeast China. Being located in the transitional area between the temperate and cold zone, this Ramsar Site supports a representative mixture of plants from the Siberian, Inner Mongolian and Changbai floras. As the largest nature reserve located at the highest latitude in China for forest-marsh wetland ecosystems in the cold-temperate zone, the site holds the most concentrated marsh wetlands in the original coniferous forests of the Great Xingan Mountains. This site consists of permanent freshwater marshes and ponds, freshwater, tree-dominated wetlands and permanent rivers and supports 442 plant species, 216 bird species and 49 mammal species, including 22 threatened species from birds, mammals and plants such as the critically endangered Siberian Crane Grus leucogeranus and the vulnerable Siberian Musk Deer Moschus moscchiferus. This wetland also supports more than 1% of global population of 17 birds. This wetland is an important water source for over 10 million populations in Nen River Basin, as well as ensuring the recharge of 350 million m3 of water for Zhalong Nature Reserve (Ramsar Site) per year. There is a Master Plan developed for this site (2006-2015) which is being implemented.
