distribution of the aboriginal Mustang
distributed in the northern Junggar Basin, Xinjiang, North Tashan and Gansu, Inner Mongolia border Mazongshan area. Finally Mustang was 1st discovered in 1957, estimated wild population has transform extinct, there are still a number of wild horses living in captivity or semi-free escape state, since the late 80's, Mustang brought back from Europe mysterious sets of Xinjiang,mower each year, Gansu, Wuwei half dissipate into the air farming, carried out for the Broncos to return to nature, scientific experiments and research work. originated in northern Xinjiang, Gansu, Inner Mongolia, by the coalition.

habitat and habits of habitat in the desert or semi-desert steppe place. 5-20 brain team fashioned in spring and summer. In the morn or evening onward the nailed paths to normal local drinking water sources. to reed, locks and other factories because edible .5 month of mating, pregnancy and 11 months, 4-May calving, every fetus 1 Aberdeen. the age of sexual manhood is 3 years age woman, the male is 4 years old. population status of Inner Mongolia, along to records in Juyanhai seen ashore the end of the century,shanghai massage, liberation is not found in our 1957 Mustang Subei County in Gansu spring hunting of wild horses and a clear water between, and then did not understand the exact nature of message in the wild to survive. too reported that in 1966 the Hungarian zoologist Z. Kaszab in Mongolia approach the boundary with Xinjiang, where China saw a team of 8 may be the last found, yet several sometime Soviet and Outer Mongolian joint inquiry failed to detect evidence (Duncan, 1992). 1981-1983 issued along the Chinese Academy of Sciences depth of Xinjiang, Gansu and Qinghai to observe, voyage 30000km, had not found. But experts have not completely given up hope that remaining wild horses.
population status
hundred years ago, Eurasia and North America have widespread in many wild horses, but not long, in the lustful killing of human beings under entire has become extinct. Mongolian wild horses have been very narrow distribution range, only the Tianshan Mountains in Xinjiang near the northern Bayannur League of Inner Mongolia and Mongolia to the southwest, to see to.
1876, the last one died in the Ukraine, the European wasteland after the wild horses, people thought the world of wild horses have faded, very sorry. Later, the Russian browser Poole at Waco Sharansky found in the Junggar Basin, Xinjiang, Mongolian wild horses. it In this unprecedented disaster to be maintained and become survivors.
Mongolian wild horse found after that time, Russia, the United States, France and other countries ambition be the exhibit has made of the wild samples of skulls and hides. As one mature horse running fast, hard to catch, caught only a few nice horses in captivity in Ukraine and Germany, Britain, France, the United States and other menagerie. Under the well-kept, and now has 300 Mongolian wild horses live in the zoo more than 70 countries nigh the world .
mentioned that the Mongolian savage nag apt occupy the final period in 1947; and the final period I saw wild horses in the winter of 1959. Later, the essay of diplomatic zoologists have been several expeditions to Mongolia, looking west, 20 years afterward, Nothing was base. They studied from regional herders, and 40 years have seen wild horses here, namely ran there from Xinjiang. People hope Xinjiang, where there may be the merely location where there are wild horses.
employees in the field of geological reconnaissance go, have again seen the Mongolian wild horse. the coverage of their activities in the Junggar Basin, west dunes River, eastern to the general Gobi tent ditch area to a most.
caused crisis factors
fewer soak normal wild populations is due to people hunting, and livestock because pastures are occupied due to (Duncan, 1992). In increase,shanghai escort, genetic float since population level and individual level change caused by a small inbred population genetic diversity Loss of wild horses is 1 of the cardinal menaces to survival. The global propagating population there are less male births, deaths and extra cases, which skewed sex ratio, affects the telling population size of the population. As a long-term captivity immediately more or less area points breeding domesticated wild phenotypes. It is believed that wild populations are derived from 13 ancestors, of which 12 for the Mustang, the other end of the servant horse. Studies show that reserving wild horses from about 1900 starting to the 1970 Mustang gene disappears fast and continuously, the speed is approximately 10% of .1970 years afterward the gene detriment has slowed, the rate of almost 3% (Captive Breeding Specialist Group, 1990).
