Surxondaryo Region is a region (viloyat) of Uzbekistan, located in the extreme south-east of the country. Established on 6 March 1941, it borders on Qashqadaryo Region internally, and Turkmenistan, Afghanistan and Tajikistan externally, going anticlockwise from the north. It takes its name from the river Surxondaryo, that flows through the region. It covers an area of 20,100 km². The population is estimated at 2,743,201, with 80% living in rural areas. According to official data, 83% of the population are Uzbeks and 12,5% Tajiks, but several sources argue that the Tajik population might be significantly higher in this region, as well as in Samarkand and Bukhara. The highest point of the Region and also of Uzbekistan is Khazrati Sulton peak reaching 4,643 m/15,233 ft in Gissar Range.
The wildlife of Turkmenistan is the flora and fauna of Turkmenistan, and the natural habitats in which they live. Turkmenistan is a country in Central Asia to the east of the Caspian Sea. Two thirds of the country is hot dry plains and desert, and the rest is more mountainous. Very little rain falls in summer and the chief precipitation occurs in the southern part of the country in the winter and spring. The Caspian coast has milder winters.
Crimean Nature Reserve is a protected nature reserve that covers a portion of the Crimean Mountains, on the south coast of the Crimean Peninsula. The reserve protects mountain-forest and meadow steppe plants and animals, with a high level of biodiversity. It is located just north of the town of Massandra.
The Tian Shan montane steppe and meadows ecoregion covers a 2,000 km long stretch of grasslands of the isolated Tian Shan mountains of Central Asia. It is characterized by high-altitude flat and rolling grasslands.
The Jiang Nan subtropical evergreen forests ecoregion covers the mountainous divide between the lower Yangtze River and the coastal plain of South China. The region is also a climatic divide between the temperate valleys of the north and the subtropical forests of the south. The region is important for biodiversity and endemic species. The rugged limestone karst hills have been relatively protected from conversion to agriculture, and support specialized plant and animal communities.
The North Tibetan Plateau-Kunlun Mountains alpine desert ecoregion covers a long stretch of mostly treeless alpine terrain across the northern edge of the Tibet Plateau. A variety of cold, dry habitats are found, including alpine meadows, steppe, desert, and cushion plant floral areas.
The Tibetan Plateau alpine shrublands and meadows ecoregion covers the middle transition zone between the northern and southern regions of the Tibetan Plateau. The region supports both cold alpine steppe and meadows across a broad expanse of the plateau. Wild deer, antelope, and sheep roam the grasslands, but the habitat is increasingly being used to graze domestic livestock.
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.
The Central Asian southern desert ecoregion 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, 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.
The Kopet Dag woodlands and forest steppe ecoregion coincides with the Kopet Dag mountains, straddling the southern border of Turkmenistan and the northeastern border of Iran. The region is one of high biodiversity, as it includes a full range of altitude zones, and variety of habitats included juniper-wooded slopes, montane grasslands, and tugay.
The Alai-Western Tian Shan steppe ecoregion covers the foothills on the western edge of the Tien Shan and Alay Mountains of Central Asia. This territory is mostly in southeastern Uzbekistan, with a portion running north into Kazakhstan on the east side of the Syr Darya River, and a small portion in Turkmenistan.
The Gissaro-Alai open woodlands ecoregion covers the western foothills winding around two western offshoots of the Tian Shan Mountains in western Tajikistan, and parts of eastern Uzbekistan and western Kyrgyzstan, in Central Asia. The woodlands are typically of Juniper trees and shrubs, fitting the altitude zone situated between the desert valley floor, and the tree line, above which the mountain ridges are glaciated and barren.
The Middle East steppe ecoregion stretches in an arc from southern Jordan across Syria and Iraq to the western border of Iran. The upper plains of the Tigris and Euphrates Rivers dominate most of the ecoregion. The terrain is mostly open shrub steppe. The climate is arid. Evidence is that this region was once more of a forest-steppe, but centuries of overgrazing and gathering firewood have reduced tree and grass cover to small areas and along the riverine corridors. Despite the degraded condition of the steppe environment, the ecoregion is important for water birds as the rivers and reservoirs provide habitat in the arid region.
The Afghan Mountains semi-desert ecoregion covers three disconnected interior valleys in the north of the mountains of Afghanistan. These valleys are arid, and covered mostly in thorny shrubs. Overgrazing by livestock has put pressure on the grasses and the wild animals dependent on them.
The Central Persian desert basins ecoregion covers the arid steppe and desert basins of central Iran, stretching into northwestern Afghanistan. The ecoregion extends over the Central Iranian Plateau, which is surrounded by mountain ranges and has no outlets to the sea. Much of the terrain is hot sand-and-gravel desert and large salt flats. The vegetation includes many specialized species of halophytes (salt-tolerant), xerophytes (drought-tolerant), and psammophile (sand-loving) plants.
The Central Afghan Mountains xeric woodlands ecoregion covers the xeric (dry) eastern and southern slopes of the central mountain range of Afghanistan, between the sandy desert to the south and the alpine meadows in the higher, wetter region to the north. Despite the 'woodlands' in the ecoregion name, very little of the territory is forested – less than 1% – but is instead sparse vegetation or herbaceous cover.
The Red Sea Nubo–Sindian tropical desert and semi-desert ecoregion covers extremely arid land along the northeastern Red Sea, the southern Sinai Peninsula, and on a thin strip along the Israel-Jordan border. Most of the coastal land is flat, but there are high mountains in southern Sinai. Biodiversity is limited by the low moisture levels – some areas go for years without significant rain. Portions of the area support a thin savannah-like cover of widely scattered trees and scrub, surrounded by grasses that briefly flourish after a rainfall. Biodiversity is highest in the mountains of Sinai, and in the wadis and gullies that retain moisture.
The Paropamisus xeric woodlands ecoregion covers the portion of northeastern Afghanistan north of the central mountain range and the Hindu Kush Mountains. The name is derived from the Old Persian name for the region, Parupraesanna. While there are low canopy woodlands in the northeast of the ecorgegion, most of the territory is desert or xeric (dry) scrubland.
The Baluchistan xeric woodlands ecoregion covers the middle elevations of a series of mountain ranges of western Pakistan and northeastern Afghanistan, reaching 1,200 kilometres (750 mi) from the Arabian Sea in the south to the Hindu Kush Mountains and the Himalayas in the north. The characteristic vegetation is xeric (dry) woodlands of shrubs and herbaceous cover. The region has rich biodiversity but relatively few endemic species.
