Site description The site is located on the right bank of the Ishym river valley in the Akkaiyn district of the Northern Kazakhstan region. Lying on the notional line connecting the major Astana-Kokchetav interregional motorway with the north-north-easterly course of the Ishym river, Zhalyndy Lake is positioned 25 km to the west of the former and approximately 20 km to the east of the latter. The waterbody occupies the central part of the area between Dmitriyevka and Zhanalyk. Another two large settlements, Ortalyk and Alka, connected by the line of a major country road, lie to the north of the lake. The lake is situated close to the southern boundary of the large Smirnovsky State Nature Preserve. The IBA forms part of the expansive lake country occupying the entire outer edge of the southern West-Siberian Lowlands. The major land form and vegetation is forest-steppe. About 50 years ago, during the process of agricultural development, more than half of the regional virgin land (mesophylic steppe) was ploughed and converted to agriculture. As a result, nowadays, the major part of the area around the lake is crop-fields. The remaining fragments of steppe and a meadow depressions are used as pasture. Very large numbers of migrating waterfowl use the area, benefitting both from forgaing opportunities on the fields and relative protection from the preserve status. Despite its relatively small size, Zhylandy is one of the more important lakes in the region. The lake has almost solid reed cover over 85-90% of its surface. The dense reed benefits some breeding species but the lack of open water reduces the number of passage birds.

Other biodiversity The mammal fauna is poorly diversified. Murine rodents are most abundant and include Apodemus agrarius and Microtus arvalis and, in the wet habitats, Ondatra zibethica and Arvicola terrestris. Erinaceus europaeus, Neomys fodiens, Lepus timidus, Lepus europaeus, Mustela erminea and Mustela eversmanni are often encountered. Capreolus pygargus, Vulpes vulpes and Vulpes corsac are encountered occasionally. The dominant emergent vegetation is Phragmites australis. It occurs in some areas together with Typha angustifolia and Scirpus lacustris, while the muddy shoals are covered by Carex. A few patches of steppic meadows, featuring an assortment of rich-herbage-motley-turf-grass associations, remain. The major constituents of these floral compositions are Filipendula hexapetala, Rumex confertus, Achillea millefolium, Poa sp., Bromus inermis, Agrostis alba and Alopecurus sp. On saline areas Salicornia and Limonium sp occur. The isolated stands of deciduous forest are comprised, in general, of a few species of birch (including Betula verrucosa and B. pubescens) and aspen, the underbrush is Rosa sp.

Protection status The lake is situated close to the southern boundary of the large Smirnovsky State Nature Preserve (Zakaznik).
