China's Migratory Bird Sanctuaries along the coast of the Yellow Sea-Bohai Gulf (Phase I) were inscribed on the World Heritage List as a natural site on Friday at the ongoing 43rd session of the UNESCO World Heritage Committee in Azerbaijan's capital of Baku. Migratory Bird Sanctuaries along the coast of the Yellow Sea-Bohai Gulf of China are located in the Yellow Sea ecoregion, containing the world's largest continuous mudflat seashore. It is the central node of the East Asian-Australasian Flyway (EAAF), which is the most threatened migratory flyway worldwide and boasts the largest number of endangered and critically endangered species. The area has a high biodiversity, with about 280 species of fishes and more than 500 species of invertebrates, providing a variety of food resources for millions of migratory birds.
