Key Achievements

Good Governance

Jiangsu Yancheng Wetland Rare Birds National Nature Reserve (referred to as the Yancheng Reserve) is divided into core areas, buffer zones, and experimental zones according to ecosystem functions, conservation objectives, and utilization values, implementing holistic protection, zoned management, and differentiated administration.

1. The “Yancheng National Rare Birds Nature Reserve Management Measures” and the “Yancheng City Yellow Sea Wetland Protection Regulations” have been formulated and issued, clarifying the requirements for protection management and providing a solid institutional guarantee for the conservation, management, and construction of the Yancheng Reserve.

2. The local government has established a joint meeting system for the management of the Yancheng Reserve, with the responsible vice mayor as the convener, to coordinate the protection and development of the Yancheng Reserve at a high level.

3. The reserve management office has established a cooperation mechanism for the supervision and management of the ecological environment of nature reserves with local government departments such as the ecological environment and natural resources, increasing law enforcement efforts to effectively curb actions that damage the ecosystem.


Conservation

After years of protection, the ecological environment quality of the Yancheng Nature Reserve has achieved significant results:

1. The coastal wetland ecosystem has been effectively protected, with the main protected species’ populations showing a steady increase. The proportion of natural wetland area and unused sea area within the reserve has grown significantly, with various landscape patches showing a dense pattern and low fragmentation;

2. The population of the flagship species, the red-crowned crane, has increased from 321 to 508 during the wintering period, and the wintering populations of key species such as the white-naped crane and the oriental stork have reached historical highs;

3. Species diversity has increased, with the total number of recorded species in the reserve rising from 2,153 to 2,552, and the number of national key protected wild animals and plants increasing from 124 to 142.


Community benefits

Yancheng Nature Reserve adheres to the concept that green mountains and clear waters are as valuable as mountains of gold and silver, innovates the community co-management mechanism, encourages and supports the surrounding communities to develop green industries, and achieves community co-governance and sharing:

1. Innovate the community co-management mechanism, establish an ecological patrol post system, and absorb 26 community volunteers to participate in the patrol on a regular basis, effectively supplementing the daily patrol forces while increasing the income of residents.

2. Take the lead in initiating and actively promoting the substantial operation of the “Yancheng Yellow Sea Wetland Ecological Agriculture Industry Promotion Association”, create the “Famous Crane” ecological agricultural product regional public brand, and promote a batch of traditional planting and breeding projects to green transformation.

3. The brand effect of the nature reserve drives the development of surrounding communities, and the brand effect of world natural heritage sites, international important wetlands, and other brands continues to expand, attracting local governments to increase investment around the nature reserve. Dongtai Jiaogang World Heritage Town, Huangjian Chinese Red-crowned Crane Town, Xinyanggang Ecological Fishing Port Town, Huangshagang (Special) Fishing Port Town, and Xingnong Village Tidal Flat Art Village have all been established around the nature reserve, significantly improving the quality of life for community residents.

SUMMARY OF TRENDS AND RESULTS
Cultural Value: Although there are no directly protected geological relics or historical and cultural values within the reserve, based on the wetland ecosystem and local cultural characteristics, the reserve has deeply explored and disseminated wetland culture and red-crowned crane culture.
Monitoring of Cultural Values: In recent years, the Yancheng Municipal Government has attached great importance to the protection, exploration, and dissemination of wetland cultural values. Using the World Natural Heritage as a prestigious brand, the city has created the image of an "International Wetland, Coastal Green City" and has developed the "Three Treasures" IP of the Yellow Sea Wetland. It has also established cultural propaganda platforms such as the Yellow Sea Wetland Museum and the Sea Salt Museum, achieving the protection and promotion of intangible cultural heritage originating from within the reserve. The reserve has also actively focused on themes such as wetland science, wetland culture, red-crowned crane culture, and the spirit of Xu Xiujun to build the Red-crowned Crane Museum and has carried out a variety of rich and colorful nature education activities.
The natural heritage within the nature reserve has been effectively protected. The wetland culture and red - crowned crane culture have been effectively protected, excavated and disseminated, and a local - characteristic IP has been created. Centered around themes such as wetland science, wetland culture, red-crowned crane culture, and the spirit of Xu Xiujuan, a distinctive brand for nature education has been created, and a wide range of nature education activities are carried out.
In recent years, the Yancheng Municipal Government has been committed to building an “International Wetland, Coastal Green City,” creating the “Lucky Three Treasures” IP of the Yellow Sea Wetland. It has also established wetland cultural propaganda strongholds such as the Yellow Sea Wetland Museum and the Sea Salt Museum, achieving the protection and promotion of intangible cultural heritage originating from the protected area. Three intangible cultures, including salt - drying skills, have been selected into the provincial intangible cultural heritage list. Six intangible cultures, including sea - salt - making skills, have been selected into the municipal intangible cultural heritage list. The protected area has specifically built a museum themed around the red - crowned crane. As the only red - crowned - crane - themed science popularization museum in China, it allows the public to explore the mysteries of the red - crowned crane's growth, experience the brilliant world of crane culture, and listen to “A True Story.” Since its opening, the museum has received more than 400,000 visitors from all walks of life. In 2023, when California Governor Gavin Newsom visited the area, an artificially bred red - crowned crane guided and saw him off. The video went viral on the Internet. Newsom and his wife named the crane California, which has become a symbol of Sino - US friendship. Since 2019, the protected area has actively carried out nature education, forming characteristic brands such as “The Birth of Crane Baby,” “Wetland Science Popularization in Schools and Communities,” “Wetland Science Knowledge Competition for Primary and Middle Schools,” and “Yancheng Wetland, My Home.” Every year, more than 50 nature education activities are held, with tens of thousands of direct participants and over 100 million online viewers.
