CCTV News: The breeding and protection of Chinese merganser is crucial. Faced with the dilemma of increasingly scarcity of natural nests, relevant protection departments in Jilin Province have taken active actions to fully protect the survival and reproduction of Chinese merganser through the development of artificial bionic nest boxes, the promotion of the "Chinese Merganser Housing Project", special scientific research, and strengthen law enforcement guarantees.
Natural nests are scarce. Artificial bionic nest boxes help reproduce
The elderly tree holes with a diameter of 30 to 50 cm are the cradle of the life of Chinese merganser for continuing their bloodline. With the renewal and evolution of the Changbai Mountain forest system, the natural tree holes suitable for them have decreased year by year. The staff of Yuanchi Wetland Reserve have begun to develop artificial bionic nest boxes since 2015.
Carry out the construction of "Housing Project" to help population recovery
The 17 simulated nests hanging in the Yuanchi Reserve in recent years have been selected by picky ducks, and the breeding success rate has been greatly improved. At the same time, since the fall of 2022, the Jilin Provincial Forestry and Grassland Bureau has organized the construction of the "House Project" of Chinese merganser throughout the province to promote the recovery and growth of the wild population of Chinese merganser.
Research on the secrets of survival of Chinese merganser empowering scientific research
Since 2020, Jilin Province has relied on Northeast Normal University and other universities and research institutes to coordinate the special research on Chinese merganser species.
Three-dimensional patrol and escort to build a solid ecological security protection network
Protection work not only continues to make efforts in habitat environmental governance, but also requires more comprehensive law enforcement guarantees. In recent years, the Changbaishan Public Security Bureau has continued to deepen "ecological policing" to create a safe habitation and breeding environment for Chinese merganser. It has basically eliminated the phenomenon of illegal fishing in protected areas and ensured the sufficient food source of Chinese merganser.
