Site description The site consists of a group of waterbodies 80 km to the south-west of Astana and just to the east of Korgalzhyn village, 15 km to the south of the motorway connecting these two points. The lakes form part of the eastern periphery part of the Tengiz lake system and consist of Zhanybekshalkar, Uhyalyshalkar, Zhylandyhalkar and Shiyshalkar Lakes, arranged in a line stretching 25 km, along the course of the Nura river not far from the point where it enters Tengiz lake. Although the edges of the wetland complex were long ago damaged by ploughing, the relative abundance of swampy areas and patches of waterlogged saline land, especially in the environs of Shiyshalkar, hampers further encroachment and the land around the shores of the lakes are still largely intact. Away from the lakes there are numerous cultivated fields, predominantly wheat, though some are abandoned. Rarely the surrounding plain retains sparse dry steppe and semi-desert vegetation. The shores and shallows of the lakes sustain an exuberant growth of reed.

Other biodiversity The typical dry steppe faunal communities are supplemented in the areas of the shoreline depressions and marshes by wetland complexes. The natural vegetation complexes have been preserved on a small portion of the lakes’ environs: Stipa, Festuca and Artemisia are the main species. Groups of Karagana and Spirea sp are not uncommon.
