Site description The site is a cluster of waterbodies situated 80 km to the south-west of the regional centre, Astana, and approximately 50 km to the east of Korgalzhyn village. It is part of a large chain of lakes running along a shallow, approximately 100 km long trough, running parallel to the course of the Nura river at a distance of 30 km and represents the eastern periphery of the Tengiz lake system. The majority of the lakes form elongated clusters stretching along the floor of a few linear depressions that represent the historical course of the Nura river. The lakes of the IBA (Zharlykol, Karasor, Uzynkol and Aschikumkol) occupy the middle section (27 x 8 km) of the chain of waterbodies running north-east from the south of Tengiz lake. The bio-geography of the region corresponds to that of the dry steppe zone. The main land form in the vicinity of the lakes is an undulating plain. The natural vegetation is herb-grass associations typical for areas intermediate between the regions of proper steppe and semi-desert. The shallow lakes, with waters of low salinity, support an exuberant growth of reed. A considerable portion of the depressions around the lakes contain saltmarshes or alkaline plots.

Other biodiversity The dominant emergent plant is Phragmites australis occurring in some places Typha angustifolia and Scirpus lacustris, while the muddy shoals are often overgrown Carex. On the outskirts of the lake system and in the immediate proximity of many waterbodies, a few plots of steppic landscape remain, though these are generally severely degraded by intensive grazing, but still retain the remnants of the rich-herbage-motley-turf-grass associations.
