The "Beidaihe Wetland" named by the International Wetland Conservation Organization is a wetland along the beach. This wetland is an important passage for migratory birds and one of the four international bird watching resorts. The location advantage is important. The wetland types are diverse, including forests, beaches, lagoons, rivers and so on. Here, 412 species of birds have been found, accounting for one-third of the total birds in China, and nearly 70 species of national key protected animals. For this reason, a large number of domestic and foreign bird researchers and bird lovers are attracted to academic research and bird watching activities every year.
