Geography
editThe landscape of the reserve is arid, with extensive ridged sand dunes some 15–20 m (49–66 ft) in height and 8–10 m (26–33 ft) in length in many areas, large areas of sand dune and valley-like depressions.[3] Black saxaul (Haloxylon aphyllum), rare to most part of Central Asia covers more than 1,470 km2 (570 sq mi), approximately 4.5% of the territory of the reserve. The soils have sandy subsoils, but some "21 trees, 104 grasses, 8 mushrooms, 1 moss, 68 soil algae and 197 fungi" grow within the reserve.[3]
History
editThe Repetek sandy desert scientific station was organized in 1912 by the decision of the Russian Geographical Society, and the reserve was established in 1928 on the base of the scientific station.[4] During the Soviet period the reserve belongs to the Institute of Deserts of the Turkmen SSR Academy of Sciences. The list of scientific publications concerning with the Repetek sandy desert station and the biosphere reserve since 1982 to 1991 consists of about 250 papers (30% on landscape structure and geography, 20% on botany and 50% on zoology).[5]
The Institute of Deserts, Flora and Fauna of the Academy of Sciences of Turkmenistan was established in 1962 to study ways of reclaiming desert land for economic use in the reserve.[6] A museum is present at the site.[7]
Environmental protection
editThe Repetek Biosphere State Reserve is part of an Important Bird Area (IBA) and since 1979 has been an under the monitoring of UNESCO but "the site is under the administration of the Ministry of Nature Protection of Turkmenistan".[3] The reserve "supports the most complete assemblage of bird species typical of the sand desert of the Karakum" and "has an important population of Goitered Gazelle (Gazella subgutturosa) which is listed as Vulnerable (VU) in the IUCN Red List".[3]
Climate
editRepetek Biosphere State Reserve has a desert climate (Köppen climate classification BWk), with cool winters and very hot summers. Rainfall is generally light and erratic, and occurs mainly in the winter and autumn months. On 28 July 1983, Repetek Biosphere State Reserve recorded a temperature of 50.1 °C (122.2 °F), which is the highest temperature to have ever been recorded in Turkmenistan and the former Soviet Union, and higher than the record high temperatures ever recorded for Europe or South America.[8][9]
