The 26th International Day for Biological Diversity is on May 22. Strolling along the Jiangong Lake in Haimen district, Nantong, one can see the shimmering waves on the lake surface, wild ducks foraging and frolicking on the water, and swaying reeds in the breeze.

Located at the confluence of the Yangtze River and the Yellow Sea, Haimen is an important stopover for migratory birds and a natural habitat for aquatic life. Rare bird species such as Saunders's gull and Chinese egret now reside here year-round. Finless porpoises frequently swim in groups off the coast, and Chinese sturgeons occasionally appear in the waters. 

At present, the development in Haimen is significantly fueled by ecological benefits. Earlier this year, the Yunqi Xingjing International Cultural and Tourism Base was inaugurated, harnessing the premium ecological resources of Jiangong Lake. Since its opening, the base has drawn 150,000 visitors, underscoring its appeal and the importance of sustainable tourism in the region. 

Technology also provides robust support for ecological protection. A biodiversity observation facility operates 24/7 in Haimen, monitoring atmospheric conditions, water quality, biodiversity, and other ecological indicators in real time. 

Furthermore, Haimen has deployed China's first underwater acoustic real-time monitoring system for false killer whales and finless porpoises, providing real-time digital protection for rare aquatic life. 

Since 2019, Haimen has led the city in conducting the first round of biodiversity surveys, documenting 1,216 species, including 16 key nationally protected species and 20 rare and endangered species listed by the International Union for Conservation of Nature. 

It has also invested over 1.3 billion yuan ($191.97 million) to close and relocate all 32 chemical companies within one kilometer of the Yangtze River. What was once a dreary industrial zone has now transformed into a vibrant ecological corridor.

On this International Day for Biological Diversity, Haimen further established a public welfare alliance through the collaboration of various departments, including several government agencies, research institutions, and companies, and launched a public cooperation mechanism for biodiversity conservation. 

The initiative is designed to enhance the routine management of protected natural areas and the regular monitoring of biodiversity. It aims to promote the harmonious development of ecological protection, local green industries, and coastal agriculture and fisheries, achieving a triple win in ecological, social, and economic benefits.
