[16] Two-thirds of births are twins; the remaining third of births are single calves. [11] An extinct species of Saiga, S. borealis, has been identified from the Pleistocene of northern Eurasia. The average life span of saiga is only around three to four years and if females do not mate every year the species can rapidly decline (2). Today, the dominant subspecies (S. t. tatarica) is only found in one region in Russia (in the Republic of Kalmykia and Astrakhan Oblast) and three areas in Kazakhstan (the Ural, Ustiurt, and Betpak-Dala populations). The high price and demand for horns drove radical hunting. [24], Cherny Zemli Nature Reserve was created in Russia's Kalmykia Republic in the 1990s to protect the local saiga population. In Kazakhstan, the number of saigas was found to be increasing, from around 21,000 at the beginning of this millennium to around 81,000 in January 2010. Working to sustain the natural world for the benefit of people and nature. Pleistocene Park in northern Siberia plans to introduce the species. Saigas are dependent on weather and affected by climate fluctuations to a great extent due to their migratory nature. They can cover long distances and swim across rivers, but they avoid steep or rugged areas. They graze on over one hundred different plant species; the most important being grasses, prostrate summer cypress, saltworts, fobs, sagebrush, and steppe lichens. [23] The saiga is classified as critically endangered by the IUCN. Цоохор ирвэс хүмүүн биднээс тусламж хүсч байна. The mating season starts in November, when stags fight for the acceptance of females. For generations, Tungalag spring has been an oasis in Mongolia’s far west semi-desert Altai-Sayan Ecoregion. In captivity, young saigas occasionally nurse from unrelated adults; however, this has never been observed in the wild.

[32] At that price, each horn would cost over US$4,600. [27] By April, 2016, the saigas appear to be making a comeback, with an increase of population from 31,000 to 36,000 in the Betpak-Dala area. [9] The cladogram below is based on the 2013 study. In the winter, the coat becomes thicker and longer. A portion of the Ustiurt population migrates south to Uzbekistan and occasionally Turkmenistan in winter. Kalmykia's president Kirsan Ilyumzhinov announced 2010 as the Year of Saiga in Kalmykia. [7], In a revision of the phylogeny of the tribe Antilopini on the basis of nuclear and mitochondrial data in 2013, Eva Verena Bärmann (of the University of Cambridge) and colleagues showed that the saiga is sister to the clade formed by the springbok (Antidorcas marsupialis) and the gerenuk (Litocranius walleri). A prominent feature of the saiga is the pair of closely spaced, bloated nostrils directed downward. [28], The Mongolian saiga (S. t. mongolica) is found in a small area in western Mongolia around the Sharga and Mankhan Nature Reserves. [citation needed] By June 2015, no definitive cause for the epizootic had been found. The etiology was confirmed to be goat plague in early 2017. At one point, some conservation groups, such as the World Wildlife Fund, encouraged the hunting of this species, as its horn was presented as an alternative to that of a rhinoceros. As a result the quality of the pastures for saiga has deteriorated (7). It is the sole extant member of its genus and is classified in the family Bovidae. These horns, thick and slightly translucent, are wax-coloured and show 12 to 20 pronounced rings. [2], During the last glacial period, the saigas ranged from the British Isles through Central Asia and the Bering Strait into Alaska and Canada's Yukon and Northwest Territories. Saigas' horns, meat, and skin have commercial value and are exported from Kazakhstan. [45], Biologist Murat Nurushev suggested that the cause might be acute ruminal tympany, whose symptoms (bloating, mouth foaming, and diarrhea) had been observed in dead saiga antelopes. (Rubin, et. [citation needed] In springtime, mothers come together in mass to give birth. [12] Fossils excavated from the Buran Kaya III site (Crimea) date back to the transition from Pleistocene to Holocene. Demand for the horns has wiped out the population in China, where the saiga antelope is a class I protected species, and drives poaching and smuggling.[30]. All the saiga populations have suffered from habitat degradation, poaching and disturbance. Two distinct moults can be observed in a year, one in spring (April to May) and another in autumn (late September or early October to late November or early December). Saiga are nomadic animals and undertake seasonal migrations from summer pastures in steppe grassland to winter pastures in desert areas (8). It is the sole extant member of its genus and is classified in the family Bovidae. [37] Starting in 2011, Kazakhstan has built more than 150 km of wire fence at the border with Uzbekistan. [12] Fossils excavated from the Buran Kaya III site (Crimea) date back to the transition from Pleistocene to Holocene. It is extinct in China and southwestern Mongolia. The high price and demand for horns drove radical hunting. By 1950, two million of them were found in the steppes of the USSR. Given that poaching for domestic consumption is now a major threat, strengthening of anti-poaching law enforcement is crucial. [16] Two-thirds of births are twins; the remaining third of births are single calves. In June 2015, E.J. About 45–80 dm2 of skin can be yielded from one individual depending on its age and sex. The bacterium occurs in the antelopes and is normally harmless; the reason for the change in behavior of the bacterium is unknown. A 2010 study revealed that a steep decline has occurred in the genetic variability of the saiga since the late Pleistocene-Holocene, probably due to a population bottleneck. [30] The saiga's decline being one of the fastest population collapses of large mammals recently observed, the MoU aims to reduce current exploitation levels and restore the population status of these nomads of the Central Asian steppes. During the Pleistocene, they also occurred in Beringian North America and the British Isles. Saigas' horns, meat, and skin have commercial value and are exported from Kazakhstan. (Heptner, et. [44] More than 120,000 carcasses had been found by late May 2015, while the estimated total population was only 250,000. [42], In May 2015, uncommonly large numbers of saigas began to die from a mysterious epizootic illness suspected to be pasteurellosis. [21] Occupants limited saiga's passage to water resources and the winter and summer habitats. Key Reproductive Features: gonochoric/gonochoristic/dioecious (sexes separate); sexual. Mature males have almost vertical horns; these are semi translucent and are ringed in the bottom sections (6). Female saigas reach sexual maturity at 7 to 8 months while the males which reach sexual maturity at 2 years. In summer, the coat appears yellow to red, fading toward the flanks. One wild born specimen was about 10.5 years old when it died in captivity (Richard Weigl 2005). It is considered to be more important to fund national conservation action than to improve the international trade control (7). Pleistocene Park in northern Siberia plans to introduce the species. ", "Welcome to the Saiga Conservation Alliance", "Emergency appeal: saigas of the pre-Caspian region of Russia under extreme threat", "Mystery over mass antelope deaths in Kazakhstan", "Saiga Antelope Death Toll in Kazakhstan Reaches 85,000", "Catastrophic Collapse of Saiga Antelopes in Central Asia", "Saiga Population Grows After Mysterious Epidemic", "Memorandum of Understanding concerning Conservation, Restoration and Sustainable Use of the Saiga Antelope (, "Chinese 'Cooling Drinks' May Contain Endangered Saiga Antelope Horns", "Kazakhstan extends Saiga antelope hunting ban until 2021", "ОХОТНИЧЬЯ КУХНЯ. [41] Consequently, small steppe rivers dry faster, limiting water resources to large lakes and rivers, which are usually populated by human settlements. An estimate of 14% or more of available pastureland is considered degraded and useless. Another main cause of the saiga's decline is the overgrazing of its pastures, general habitat degradation and construction of roads and canals. [citation needed], Saigas, like the Mongolian gazelles, are known for their extensive migrations across the steppes that allow them to escape natural calamities.
