Why We Care
Poyang Lake is the largest lake in the Yangtze River basin and winter home to 400,000 waterbirds, more than any other location in East Asia. Poyang provides winter habitat for almost all of the world's critically endangered Siberian Cranes. The lake basin is threatened by hydrologic changes caused by dams and water diversion projects, as well as declining water quality that could impact the aquatic food plants on which the cranes and other waterbirds depend.
What We Do
ICF is collaborating with Poyang Lake Nature Reserve to study the linkages among cranes, aquatic plants, and water levels within the Poyang Lake basin, a long-term study that is providing vital information for evaluating future water development projects and lake management issues. ICF recently worked with the IUCN SSC Crane Specialist Group to prepare a comprehensive report on the management of the Poyang Lake wetlands.

In spring five rivers from the south swell with rains as they flow into Poyang Lake, wintering area for the majority of the world’s Siberian Cranes. In summer, the much larger Yangtze River rises with floods coming from the west, often sending water into the lake. The water level within the lake basin fluctuates by as much as 11 meters between summer and winter.
This scale of change, and the strength of the summer flooding, has prevented development of major parts of this wetland and protected the Siberian Crane’s winter home; however changes caused by dams and other water development projects could alter this delicate system and the future for Siberian Cranes.
