According to the WeChat public account of Poyang Lake National Nature Reserve on October 13, in order to meet the upcoming peak of wintering migratory birds migration and ensure the ecological safety of wintering migratory bird habitats, Shahu Station of Poyang Lake Nature Reserve actively took a number of effective measures to unite relevant departments to escort migratory birds to overwinter.
According to the news, after the detection of the anti-billed sandpiper in the jurisdiction on September 20, Shahu Station increased the frequency of daily lake patrols, strengthened the monitoring of migratory birds, and carried out protection work in a timely, scientific and efficient manner. At the same time, strengthen supervision of the lake area, dissuade people and vehicles entering the lake area, and create a good atmosphere of bird protection in the lake area. In order to cope with the drought situation in Poyang Lake, Shahu Station has organized patrol forces since September, leased water pumps, diverted river water into the lake, and carried out all-weather ecological water replenishment of the managed lake, effectively reducing the impact of drought on wetlands, enhancing wetland functions, and creating a good habitat for migratory birds.
In addition, in order to prevent vehicles from entering the lake and destroying the wetland, Shahu Station excavated ecological ditches around the lake area, set up warning signs, set up restriction poles to block, and arranged special personnel to dissuade anglers at the lake bayonet. It effectively repels vehicles and personnel from the lake, and protects the wetland and wintering migratory bird habitat in the jurisdiction.

Duchang Migratory Bird Nature Reserve is one of the most typical lake wetland reserves in Poyang Lake area, which has an important ecological location, large ecological volume and rich biodiversity in the overall pattern of migratory bird protection in Poyang Lake Wetland. According to a report by the Rong Media Center of Duchang County on October 11, the latest news from the County Migratory Bird Nature Reserve Management Bureau said that according to the results of regular monitoring and investigation, more than 4,000 water birds have arrived in the Duchang Lake area of Poyang Lake to roost.
In the normal year of Poyang Lake's water level, more than 200,000 migratory birds are distributed in many saucer-shaped lakes and open and flat grassy beaches every winter, of which 25 species of birds under national level I and II key protection. According to statistics, the Duchang County Migratory Bird Nature Reserve Management Bureau carried out field monitoring in three routes, and more than 30 species of birds were counted. This year, due to extreme climate change, Poyang Lake has experienced a continuous drought, which has adversely affected the overwintering of migratory birds.
In the report, Li Yue, director of the Duchang County Migratory Bird Nature Reserve Management Bureau, said that this degree of influence is very deep, the saucer-shaped lake has basically dried up, and the moss grass and indigo grass suitable for migratory birds to feed on are not growing well, so it will have a negative impact on a large number of migratory birds overwintering. Li Yue said that in order to meet the return of a large number of migratory birds wintering, they have taken measures to ecologically replenish the saucer lake, and mowing moss grass in important distribution areas of migratory birds, while strengthening the protection and management of migratory birds to ensure the safe overwintering of migratory birds.
The water of the main channel of Poyang Lake is pumped by the pump and relayed by the artificial canal and entered into the disc lake.
According to Duan Qingxian, president of the Poyang Lake Wildlife Rescue Association in Duchang County, the continuous drought in Poyang Lake this year has had a serious impact on the Disc Lake and the surrounding wetlands, resulting in the foraging and habitat of migratory birds. In order to expand the surface area of the lake, promote the breeding of submerged plants and fish, shrimp, snails and mussels in the lake, and increase the habitat and feeding space of migratory birds, the reserve mobilizes manpower and machinery to work together, pumping water from the main channel of Poyang Lake in the distance, and then transferring water to the disc lake 24 hours a day through water pipes and artificial channels. With the infusion of the lake, the water surface of the saucer lake continues to expand, creating a good habitat for the upcoming migratory birds.
