Recently, when the staff of Nanshui Lake National Wetland Park in Guangdong Province counted the number of migratory birds this winter, they monitored and recorded 34 Chinese mergansers staying in Nanshui Lake to inhabit and winter, which is the third year that Chinese mergansers have wintered in Nanshui Lake.
It is understood that the Chinese merganser duck is a national first-class protected wild animal, the habitat environment requirements are very high, mainly live in the environment with clear water quality, open water surface, abundant food and less human interference, is an indicator species to test the quality of the ecological environment, so it is also known as the "ecological environment vane" and "ecological test paper of the water ecological environment".
This is the third year in a row that we have monitored the wintering of Chinese mergansers in Nanshui Lake, and the number has gradually increased from the initial 2 to 34 at present, and their wintering activities are mainly located under the ladder of Nanshui Lake and Longxi Haidaiku Bay. According to the staff of Nanshui Lake National Wetland Park, in recent years, with the continuous improvement of the ecological environment of Nanshui Lake Wetland, in addition to Chinese mergansers, there are also a large number of migratory birds such as egrets to stay here to inhabit and winter.
It is understood that the Nanshui Lake National Wetland Park attaches great importance to this, continues to carry out monitoring work, strengthens patrol management and protection, delineates the activity area of the Chinese mergansers, cleans up the fishing nets and light nets in the area, replaces 4 warning buoys, and prints 100 warning stickers, so as to create a good wintering environment for the migratory birds of the Chinese mergansers.
In 2023, with the support of special funds for the construction of national parks, the Nanshui Lake National Wetland Park Management Office will carry out the construction of the "Green Mountains and Clear Water, Guangdong and South Water Lake AI Ecological Environment Monitoring and Early Warning System", and the AI bird monitoring system has been captured 310 times in 2 months since the trial operation in early November last year, which has greatly improved the bird monitoring capacity.
In the next step, Nanshui Lake National Wetland Park will continue to do a good job in the protection of migratory birds of Chinese mergansers, not only to let migratory birds "come to visit every year", but also to achieve "more and more new visitors", continuously strengthen the monitoring of the ecological environment, improve the level of biodiversity conservation in Nanshui Lake, and promote the formal establishment of Nanling National Park with high quality.
