The Central Asian southern desert ecoregion (WWF ID: PA1312) is an arid but ecologically active region between the east coast of the Caspian Sea and steppes at the base of the mountains of central Asia. Most of Turkmenistan and eastern Uzbekistan is in this ecoregion. The winters are milder than in the cold desert to the north (the Central Asian northern desert ecoregion), and a large number of endemic species have adapted to living in the particular climate and soil of the region. As with sandy deserts in general, the region is notable for high numbers of endemic species of reptiles and insects. [1] [2]

Location and description

The ecoregion covers the arid territory from the Caspian Sea on the west, almost to the Pamir-Alay Mountains to the east. Most of Turkmenistan and the eastern half of Uzbekistan is this region. Covered are the coastal plains of the Caspian, the Krasnovodsk and Ustyurt Plateaus of northwest Turkmenistan, the Karakum Desert ('Black Sand' desert) of central Turkmenistan, and the Kyzylkum Desert ('Red Sand' desert) of eastern Uzbekistan and a portion of southern Kazakhstan between the Syr Darya and Amu Darya Rivers. The ecoregion is bisected by the thin ecoregion of the Central Asian riparian woodlands of the Amu Darya River.

Climate

The climate in the surrounding region is Cold desert climate (Köppen climate classification (BWk)). This climate features hot desert conditions in the summer, but cooler than hot deserts. Winters are cold and dry. At least one month averages below 0 °C (32 °F). Precipitation is 125–170 mm/year, with the little precipitation occurring in the winter and spring. [3] [4] [1]

Flora and fauna

Soil type and quality is one of the main drivers of plant species across the ecoregion. Sandy areas typically feature White saxaul ( Haloxylon persicum ) and Black saxaul ( Haloxylon ammodendron ), which are short hardy trees that are tolerant of drought and poor soils. They have extensive root systems to hold in the sand. Thin sandy and loamy soils support many species of sagebrush and salt-tolerate saltworts ( Salsola ). Saline solonchak soils support salt-tolerant succulent semi-shrubs such as Halostachys , Halocnemum strobilaceum and Seepweeds ( Suaeda ). [1]

Common mammals include the long-earned hedgehog ( Hemiechinus auritus ), Brandt's hedgehog ( Paraechinus hypomelas ), and Tolai hare ( Lepus tolai ). Also common are gerbils and ten species of jerboas. [1]

<span class="mw-page-title-main">Amu Darya</span> River in Central Asia

The Amu Darya, also called the Amu, the Amo, and historically the Oxus, is a major river in Central Asia and Afghanistan. Rising in the Pamir Mountains, north of the Hindu Kush, the Amu Darya is formed by the confluence of the Vakhsh and Panj rivers, in the Tigrovaya Balka Nature Reserve on the border between Afghanistan and Tajikistan, and flows from there north-westwards into the southern remnants of the Aral Sea. In its upper course, the river forms part of Afghanistan's northern border with Tajikistan, Uzbekistan, and Turkmenistan. In ancient history, the river was regarded as the boundary of Greater Iran with Turan, which roughly corresponded to present-day Central Asia. The Amu Darya has a flow of about 70 cubic kilometres per year on average.

<span class="mw-page-title-main">Central Asian northern desert</span> Ecoregion in Kazakhstan and Uzbekistan

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, the winters are cold at −10 to −15 °C 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 Alashan Plateau semi-desert ecoregion covers the southwestern portion of the Gobi Desert where precipitation in the mountains is sufficient for a short part of the summer to support sparse plant life. The terrain is basin and range, with elevations from 1,000 to 2,500 metres.

The Central Asian riparian woodlands ecoregion is spread out across the deserts and plains of central Asia between the Aral Sea and the mountains 2,000 kilometres (1,200 mi) to the east. The long narrow components of the ecoregion follow the large rivers fed by snowmelt, and provide critical habitat for migratory birds as they travel through the arid region. The vegetation is referred to as tugai, characterized by low tangles of trees and brush along the edges of the rivers and associated wetlands, and fed by groundwater instead of precipitation.
