A World for Birds 
Poyang Lake is a seasonal lake with a variable water level regulated by the changing flow of the Yangtze River throughout the year. It reaches its maximum water volume between March and July because of the frequent spring and summer rainfall. Every winter the lake's total surface area is reduced by between 14% and 17%, revealing huge beaches. Vigorously growing trees and grass on the beaches together with an ample water supply provide an ideal place for migrant birds and other animals to live through winter.

Renowned as the worlds biggest bird protection area, more than 300 species of birds are found at Poyang Lake with 50 species of rare birds. In recent years, the largest flock of White Cranes has been found here. More than 4,000 White Cranes migrated and assembled at the lake in 2002 making up 95% of the total number in the world.

Scenery 
The most scenic area can be found along the water channel at the northern edge of the lake. Steep cliffs and deep water combine to form an environment of great natural beauty. Here lists major attractions in Poyang Lake:

• Dagushan Hill 
• Stone Bell Hill
• Xiaogu Hill
