Central Asian northern desert

The Central Asian northern desert is an ecoregion in the deserts and xeric shrublands biome, located in the Central Asian countries of Kazakhstan and Uzbekistan. The annual precipitation ranges from 100 to 150 mm (4 to 6 in), the winters are cold at −10 to −15 °C (14 to 5 °F) and the summers hot at around 25 °C (77 °F). There are a range of habitat types including salt flats, clay desert, rocky desert and some sand desert. The vegetation consists of scanty xeric shrubs including Artemisia and Salsola. The fauna is varied, as well as mammals and birds, there are a large number of reptiles and many species of invertebrate. Some protected areas are included in this ecoregion but other parts are being degraded by conversion to farmland, overgrazing and poaching.

The Central Asian northern desert occupies southern Kazakhstan and most of Uzbekistan, and largely corresponds with the desert known as the Kyzyl Kum. This ecoregion experiences a typical cold desert climate; January mean temperatures range from −10 °C (14 °F) to −15 °C (5 °F), while July means range from 24 °C (75 °F) to 26 °C (79 °F). On average, precipitation ranges from 100 millimetres (3.9 in) to 150 millimetres (5.9 in) annually. The topography of this ecoregion is varied, featuring salty "solonchak" deserts with a great number of salt flats, clay deserts, rocky deserts, and a small area of sandy desert in the southern portion of the region.

The vegetation of this ecoregion is dominated by shrubs and semi-shrubs, with a variety of different species adapted to the different soil types found in it. Clay deserts support communities of Anabasis salsa, Salsola orientalis, and the Artemisia species A. terrae albae, A. turanica, and A. gurganica. The stony deserts support mainly Salsola arbusculae formis and Nanophyton erinaceum, while the "solonchaks" support the semi-shrubs Ceratoides papposa, Artemisia terrae albae', var. massagetovii, A. santolina, and A. songarica, shrubs such as Calligonum aphyllum, Ephedra lomatolepis as well as grasses such as Agropyron fragile.
