Site description The region represents a vast system of constant, partially and fully dried up lakes that are fed from Karasuk river. The lakes are primarily brackish but there are some fresh ones. Many lakes have large reedbeds. There are also substantial areas of steppes and salines. A large area is taken by the man-made landscapes, including the Karasuk town. Of highest conservation value are the lakes in the Karasuk town (nesting place of the White-headed duck in the 2000s) and the steppe areas around Troitskoe, where the sociable lapwing nested in the 1990s and there are still suitable habitats for it. Many wetlands of the system have favorouble conditions for rest and feeding of the birds of passage.
