Przewalski's Horse ( Equus ferus ) Population and conservation status, threats to survival, management actions These pages are part of the San Diego Zoo Global Library website. The foundation started a program of exchange between captive populations in zoos throughout the world to reduce inbreeding, and later began a breeding program of its own. [38], Mating occurs in late spring or early summer. Scientists have successfully cloned a Przewalski's horse for the first time ever, and are hopeful it could help save the endangered species. [20] In the wintertime, Przewalski's horses experience hypodermis, a condition in which their metabolic rate slows down. The Przewalski’s horse herd in Pentezug, in Eastern Hungary, represents the largest population of wild horses in the world. 1. [38] In winter, for example, the horses eat Salix spp., Pyrus communis, Malus sylvatica, Pinus sylvestris, Rosa spp., and Alnus spp. [20] In 1881, the horse received a formal scientific description and was named Equus przevalskii by Ivan Semyonovich Polyakov, based on Przewalski's collection and description,[20][19] while in 1884, the sole exemplar of the horse in Europe was a preserved specimen in the Museum of the Russian Academy of Sciences in St. The legs of Przewalski's horse are often faintly striped, also typical of primitive markings. A dark stripe continues from the mane along the backbone to a dark, plumed tail. [51][52], Le Villaret, located in the Cevennes National Park in southern France and run by the Association Takh, is a breeding site for Przewalski's horses that was created to allow the free expression of natural Przewalski's horse behaviors. Nine of them reproduced. Stallions assemble groups of mares or challenge the leader of another group for dominance. This wild equid species went extinct in the wild in the late 1960s, surviving only in zoos. [36], Horses maintain visual contact with their family and herd at all times, and have a host of ways to communicate with one another, including vocalizations, scent marking, and a wide range of visual and tactile signals. Their mountainous habitat included the Takhiin Shar Nuruu (The Yellow Wild-Horse Mountain Range). In 2011 their status was changed to endangered. In October 2007, scientists at the Smithsonian Institution's National Zoo successfully reversed a vasectomy on a Przewalski's horse — the first operation of its kind on this species and possibly the first ever on any endangered species. Their lifespan in captivity is roughly 20 years. After 1903, there were no reports of the wild population until 1947, when several isolated groups were observed and a lone filly captured. Additionally, those living in zoos feed upon hay, grain and alfalfa. Port Lympne Reserve became involved in the reintroduction of Przewalski’s horses when in 1992 10 Przewalski’s horses were sent to China and 1 in 1996. Their winter diet is very similar to the diet of domestic horses,[38] but differs from that revealed by isotope analysis of the historical (pre-captivity) population, which switched in winter to browsing shrubs, though the difference may be due to the extreme habitat pressure the historical population was under. A stallion has been cloned from an individual that has been cryopreserved since 1980. Lastly, in 2004 and 2005, 22 horses were released by the Association Takh to a third reintroduction site in the buffer zone of the Khar Us Nuur National Park, in the northern edge of the Gobi ecoregion. Both the SSP and the FPPPH, selectively breed these horses to increase genetic diversity, unlike the breeding of domestic horses for particular characteristics. In 1957, a wild-caught mare captured as a foal a decade earlier was introduced into the Ukrainian captive population. It has been suggested that this was not their natural habitat, but that instead they were like the local populations of onager, a steppe animal driven to this inhospitable last refuge by the dual pressures of hunting and habitat loss to agricultural grazing. Already extinct in the wild, their future in captivity was threatened as well. Przewalski's horse, the only true horse never to have been domesticated, is believed to be extinct in the wild. After that loss, there were estimated to be only 31 Przewalski's horses left alive in the world. But the now two-month-old colt is unique in that he is a clone. The Przewalski’s horse was once extinct in the wild. The reintroduced horses successfully reproduced, and the status of the animal was changed from "extinct in the wild" to "endangered" in 2005,[24] while on the IUCN Red List they were reclassified from "extinct in the wild" to "critically endangered" after a reassessment in 2008,[43] and from "critically endangered" to "endangered" after a 2011 reassessment. As a matter of fact, this animal is the last surviving true wild horse, from which the domestic horse originates. Meanwhile, Mongolia holds 387 free-ranging reintroduced and native-born individuals, which live in 3 areas of re-introduction. Przewalski's horses are often described as small and stocky. [22] Two scientific expeditions in 1955 and 1962 failed to find any, and after herders and naturalists reported single harem groups in 1966 and 1967, the last observation of the wild horse in its native habitat was of a single stallion in 1969. While there are about 2,000 horses today, that genetic pool is a pretty shallow puddle. Family groups can join together to form a herd that moves together. They eat their food more slowly than they do during other times of the year. Genetic analyses reveal that the wild horses reintroduced into the wild since 1992 do not show a decreased genetic variability, despite the small breeding population. It is named after the Russian geographer and explorer Nikołaj Przewalski. But due to the fragmented and small population sizes, habitat degradation, climate change, and disease, this species remains vulnerable.
