Overview. Naurzum Lake System is a natural wetland comprised of large and small lakes scattered in the steppe zone of Northern Kazakhstan. It is system with seasonally changing water levels, comprising, according to hydro-chemical water composition, a variety number of water bodies – from fresh water lakes to bitter-salt ones.
Importance for the Siberian Crane. It is the most important stop over for Siberian Cranes of the Western/Central flyway within Kazakhstan. Siberian Cranes regularly stop over at this territory both in the spring and autumn migration period. In the spring Siberian Cranes may rest at the site for up to one month.
Importance for other waterbirds. The site is a breeding area for two other crane species: Eurasian and Demoiselle Cranes. It is also a stop-over site for migratory Eurasian Cranes, and in some years summer groups of molting birds were recorded. In autumn pre-migratory congregations of Eurasian Cranes totaled up to three thousand birds and up to 132 Demoiselle Cranes.
During migration the Naurzum Lake System supports a great number of waterfowl, including 40,000 to 237,000 ducks and coots. Depending on water levels, the number of migrating geese during the period 1966-2005 fluctuated from 20,000 to 500,000. The site regularly supports more than 7% of the Black Sea-Caspian Sea population of Whooper Swans; not less than 5% of the Siberian-Caspian population of Bewick’s Swans; up to 2.5% of the Western population of Lesser White-fronted Geese; up to 7% of the population of Red-breasted Geese; and more than 1% of the Dalmatian and White Pelicans’ populations of Southwest and South Asia.
