Located in China’s eastern coast, the Yancheng Rare Birds National Nature Reserve is a vital part of the East Asian–Australasian Flyway, one of the world's major migratory bird routes, and has earned national reputation as a biodiversity hotspot. 

The area boasts 2,567 animal and plant species. Every year, more than 600 red-crowned cranes spend the winter at the nature reserve, which is also a stopover site for more than 20 million birds in their migratory journeys and the shared habitat for nearly one million birds. 

Over the past 37 years, generations of breeders have worked at the nature reserve and gradually developed a mature system for the bird’s reproduction. This year, the reserve has achieved its best result in five years since 2018, with the successful hatching of 30 young birds and an additional 20 eggs in the hatching process. The research center’s plan is to continue breeding more red-crowned cranes, create suitable conditions for releasing birds into the wild, and enhance their population. 

At present, the reserve has established a robust system to ensure ecological and environmental protection. It has also adopted new technologies such as satellite tracking, radar-based bird detection, drones, and high-altitude cameras for monitoring purposes. Regular surveys are conducted on various aspects including birds, water quality, soil and seabed dredging. These surveys provide essential data for daily management and restoration efforts.
