Barsuki Desert
The Barsuki Desert is a desert zone in the Aktobe and Kyzylorda regions of Kazakhstan. It has two parts, the Greater Barsuki ( kk, Үлкен Борсық; russian: Большие Барсуки) in the west and the Lesser Barsuki ( kk, Кіші Борсық; russian: Малые Барсуки) in the east. They are elongated strips of sand desert parallel to each other and separated by a roughly wide stretch of non-desert terrain.Барсуки Большие и Малые '''' in 30 vols. — Ch. ed. . - 3rd e ...

Sand Dune Stabilization
Sand dune stabilization is a coastal management practice designed to prevent erosion of sand dunes. Sand dunes are common features of shoreline and desert environments. Dunes provide habitat for highly specialized plants and animals, including rare and endangered species. They can protect beaches from erosion and recruit sand to eroded beaches. Dunes are threatened by human activity, both intentional and unintentional (see sand theft and sand mining). Countries such as the United States, Australia, Canada, New Zealand, the United Kingdom, and Netherlands, operate significant dune protection programs. Stabilizing dunes involves multiple actions. Planting vegetation reduces the impact of wind and water. Wooden sand fences can help retain sand and other material needed for a healthy sand dune ecosystem. Footpaths protect dunes from damage from foot traffic. The location of the dune limits the types of plant that can thrive there. Beach dunes consist of the ''foredune'', the angled si ...

North Aral Sea
The North Aral Sea ( kk, Солтүстік Арал теңізі, russian: Северное Аральское море) is the portion of the former Aral Sea that is fed by the Syr Darya River. It split from the South Aral Sea in 1987–1988 as water levels dropped due to river diversion for agriculture. In 1925 a large site containing numerous fossils of the Oligocene was discovered near the village of Akespe by the northern shore of the Aral Sea. Background The Aral Sea began shrinking in the 1960s, when the Soviet Union decided that the two rivers feeding it, the Amu Darya and the Syr Darya, would be diverted to irrigate cotton and food crops in Kazakhstan and Uzbekistan. In 1987–1988, due to an accelerated loss of water, the Aral Sea split into northern and southern parts; the southern part is the current South Aral Sea. After the fall of the Soviet Union, the government of independent Kazakhstan decided to restore the northern lake fed by Syr Darya. In 2003, the lak ...

Geography Of Kazakhstan
Kazakhstan is located in Central Asia (with 14% of the country in Eastern Europe). With an area of about Kazakhstan is more than twice the combined size of the other four Central Asian states and 60% larger than Alaska. The country borders Turkmenistan, Uzbekistan, and Kyrgyzstan to the south; Russia to the north; Russia and the Caspian Sea to the west; and China's Xinjiang Uygur Autonomous Region to the east. Topography and drainage There is considerable topographical variation within Kazakhstan. The highest point is the top of the mountain Khan Tengri, on the Kyrgyz border in the Tian Shan range, with an elevation of above sea level; the lowest point is the bottom of the Karagiye depression at below sea level, in the Mangystau province east of the Caspian Sea. Most of the country lies at between above sea level, but Kazakhstan's Caspian shore includes some of the lowest elevations on Earth. The peak Khan Tengri in the Tian Shan Mountains (and on the border with Kyrgyzstan a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halimodendron
''Halimodendron'' is a monotypic genus of legume containing the single species ''Halimodendron halodendron'', which is known by several common names, including common salt tree and Russian salt tree. It is closely related to the genus ''Caragana''. It is native to Russia and southern Asia, but it can be found on other continents where it is an introduced species, and one that is often a noxious weed. This is a deciduous spiny shrub sprawling to a few meters in maximum width and up to three meters tall. Stems branch from the base and bear clusters of about four leaflets on sharp spurs. The ends of branches narrow to spines. Flowers also appear at the ends of spurs in clusters of two to four pink pealike blossoms each one to two centimeters wide. The fruit is a black woody inflated pod about 2 centimeters long containing legume seeds. The plant has a deep and wide root system, with the lateral roots sending up new shoots. In this manner the plant forms extensive thickets. When int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calligonum Caput-medusae
''Calligonum'' is a genus of plants in the family Polygonaceae with about 80 species across the Mediterranean Sea region, Asia and North America.

Astragalus
''Astragalus'' is a large genus of over 3,000 species of herbs and small shrubs, belonging to the legume family Fabaceae and the subfamily Faboideae. It is the largest genus of plants in terms of described species. The genus is native to temperate regions of the Northern Hemisphere. Common names include milkvetch (most species), locoweed (in North America, some species) and goat's-thorn ( ''A. gummifer'', ''A. tragacantha''). Some pale-flowered vetches (''Vicia'' spp.) are similar in appearance, but they are more vine-like than ''Astragalus''. Description Most species in the genus have pinnately compound leaves. There are annual and perennial species. The flowers are formed in clusters in a raceme, each flower typical of the legume family, with three types of petals: banner, wings, and keel. The calyx is tubular or bell-shaped. Ecology ''Astragalus'' species are used as food plants by the larvae of some Lepidoptera species including many case-bearing moths of the genus ''Col ...

Ephemeral Plant
An ephemeral plant is one marked by short life cycles. The word ephemeral means transitory or quickly fading. In regard to plants, it refers to several distinct growth strategies. The first, spring ephemeral, refers to perennial plants that emerge quickly in the spring and die back to their underground parts after a short growth and reproduction phase. Desert ephemerals are plants which are adapted to take advantage of the short wet periods in arid climates. Mud-flat ephemerals take advantage of short periods of low water. In areas subjected to recurring human disturbance, such as plowing, weedy ephemerals are very short-lived plants whose entire life cycle takes less than a growing season. In each case, the species has a life cycle timed to exploit a short period when resources are freely available. Spring ephemerals Spring ephemerals are perennial woodland wildflowers which develop aerial parts (i.e. stems, leaves, and flowers) of the plant early each spring and then quickly bl ...

Artemisia (plant)
''Artemisia'' () is a large, diverse genus of plants with between 200 and 400 species belonging to the daisy family Asteraceae. Common names for various species in the genus include mugwort, wormwood, and sagebrush. ''Artemisia'' comprises hardy herbaceous plants and shrubs, which are known for the powerful chemical constituents in their essential oils. ''Artemisia'' species grow in temperate climates of both hemispheres, usually in dry or semiarid habitats. Notable species include '' A. vulgaris'' (common mugwort), '' A. tridentata'' (big sagebrush), '' A. annua'' (sagewort), '' A. absinthium'' (wormwood), ''A. dracunculus'' (tarragon), and '' A. abrotanum'' (southernwood). The leaves of many species are covered with white hairs. Most species have strong aromas and bitter tastes from terpenoids and sesquiterpene lactones, which discourage herbivory, and may have had a selective advantage. The small flowers are wind-pollinated. ''Artemisia'' species are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about five y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
