Located in the Hejing County, Xinjiang Uygur Autonomous Region, the Bayanbulak Nature Reserve was set up in 1980 specially for the protection of swan, thus becoming the first swan — protecting nature reserve in China.

The Reserve has a central zone where there is a high mountainous lake which is 30 km long from east to west and 10 km wide from south to north and is just called "Bayanbulak Swan Lake". In Mongolian language, the Bayanbulak means richly endowed water resource. Here are lush pasture and abundant biota, providing plentiful foods and fine living environment for a variety of waterfowls and migrants such as swan, barheaded goose, egret, herring gull, black stork, grey crane, etc, of which the most is swan in terms of waterfowl. There are only 5 species of swan living in the world and here are 3 species, i. e.

swan,cygent, and warted nose swan. So that this swan lake on grasslands becomes a natural paradize for swan and other waterfowl as well.
