The site is a vast wetland covering both cold and milder temperate zones on the slopes of the Grand Khingan mountain range in north-east China. It includes numerous braided rivers and oxbow lakes. Vegetation communities and habitats across the site include grasslands, forests, meadows, swamp meadows and shrub lands. The site’s soil is constantly saturated, therefore the litter of the forest and herb marshes cannot decompose and forms thick peat layers. These marshes make up about 19,460 hectares, accounting for 98% of wetlands in the site. With this mosaic of habitats, the site is home to great biodiversity, with 45 mammal, 228 bird and 35 fish species present, many of which are threatened. These include the vulnerable Siberian taimen (Hucho taimen) and the critically endangered yellow-breasted bunting (Emberiza aureola). Forest fire, drought and temperature extremes are the major threats to the ecological character of the site.
