China distributes in swamps and lakes in Qinghai and Tibet, China, and migrates to central and southern China in winter. There are a large number of them.
They breed in plateau lakes, especially saltwater lakes, and also choose freshwater lakes and open and swampy areas. They winter in lowland lakes, rivers and swamps. Plateau birds, living in plateau wetland lakes and also found in cultivated land, form small groups during migration and breeding, and can be seen breeding in mixed groups with brown-headed gulls, and also in mixed groups with black-necked cranes, red-crested poultry and other birds. They often keep a certain distance from people. In the suburbs of Lhasa, this species often gathers

Bar-headed geese are a common summer migratory bird in the Qinghai-Tibet Plateau of China. The population is large, especially in the Qinghai Lake Bird Island, where bar-headed geese are concentrated and the population is also large. The species has a wide distribution range and is not close to the critical value of vulnerable and endangered species survival (distribution area or fluctuation range is less than 20,000 square kilometers, habitat quality, population size, and distribution area fragmentation). The population trend is stable, so it is evaluated as a species with no survival crisis.

Listed in the "Red List of Endangered Species of the World Conservation Union" (IUCN) 2018 ver 3.1-Least Concern (LC).  

Listed in the "List of Terrestrial Wildlife with Important Economic and Scientific Research Value under State Protection" (item 43) issued by the State Forestry Administration of China on August 1, 2000.

The bar-headed goose is a national first-class protected animal. It is on the red list of endangered species. Because its profit is very high, the population is constantly decreasing. Therefore, there is a special protection area in Qinghai, my country, for the purpose of better protecting this type of animal.

In October 2020, the National Forestry and Grassland Administration issued the "Notice on Standardizing the Classification and Management Scope of Prohibited Wildlife", prohibiting the breeding of bar-headed geese for the purpose of eating. Except for special circumstances such as retaining a moderate amount of seed sources, farmers are guided to stop breeding.
