Baer's pochard found just 131 individuals on Liangzihu Lake, and only another three flocks of ten, eight, and three individuals at other sites. Hunting and wetland destruction are thought to be the causes of the decline; unconfirmed reports from eastern China suggest that as many as 3,000 individuals may be hunted every year. Baer's pochard breeds around lakes with rich aquatic vegetation, nesting in dense grass, flooded tussock meadows, or flooded shrubby meadows. In Liaoning, China, it is normally found in densely vegetated coastal wetlands, or around lakes and ponds surrounded by forest. In winter, it occurs on freshwater lakes and reservoirs.
