feral horse of theNorth America n west that first descended fromhorse s brought to theAmericas by the Spanish. Mustangs are often referred to aswild horses , but the more correct term isferal horse s.In 1971, the
United States Congress recognized Mustangs as “living symbols of the historic and pioneer spirit of the West, which continue to contribute to the diversity of life forms within the Nation and enrich the lives of the American people.” Today, Mustang herds vary in the degree to which they can be traced to originalIberian horse s. Some contain a greater genetic mixture of ranch stock and more recent breed releases, others are relatively unchanged from the original Iberian stock, most strongly represented in the most isolated populations.Today, the Mustang population is managed and protected by the
Bureau of Land Management . Controversy surrounds the sharing of land and resources by the free ranging Mustangs with thelivestock of theranching industry, and also with the methods with which the federal government manages the wild population numbers.Etymology and usage
Mustangs are often referred to as
wild horses but, since all free-roaming horses in America descended from horses that were originally domesticated, the more correct term isferal horse s. [ [http://biobulletin.amnh.org/D/2/3/index.html The American Museum of Natural History] When Is a Wild Horse Actually a Feral Horse?] Today, the only truewild horse is thePrzewalski's Horse , native to Mongolia.The English word "mustang" comes from the
Mexican Spanish word "mestengo", derived from Spanish "mesteño", meaning "stray" or "feral animal". The Spanish word in turn may possibly originate from theLatin expression "animalia mixta" (mixed beasts), referring to beasts of uncertain ownership, which were distributed in shepherd councils, known as "mesta s" inmedieval Spain . [ Websters Third International Dictionary Unabridged ] A "mestengo" was any animal distributed in those councils, and by extension any feral animal.History
Horses lived in
North America inprehistoric times, but died out at the end of the lastice age around 10-12,000 years ago, possibly due to climate change or the impact of newly-arrived human hunters. [ [http://news.nationalgeographic.com/news/2006/05/0501_060501_ice_age.html "Ice Age Horses May Have Been Killed Off by Humans"] "National Geographic News," May 1, 2006.] Horses returned to the Americas by theConquistadors , beginning when Columbus imported horses fromSpain to theWest Indies on his second voyage in 1493. [Bennett, Deb. "Conquerors: The Roots of New World Horsemanship."Amigo Publications, 1998, pp. 150 ISBN 0-9658533-0-6] They returned to the mainland with the arrival of Cortés in 1519. [Henry, Marguerite and Wesley Dennis. "All About Horses." Random House, 1962. ASIN: B000MAJIB0]The first Mustangs descended from
Iberian horse sJ. Frank Dobie, "The Mustangs", Boston:Little, Brown and Company, seventh printing, 1952. LC no. 52-6802 ] brought toMexico andFlorida . Most of these horses were of Andalusian, Arabian and Barb ancestry. Some of these horses escaped or were stolen by Native Americans, and rapidly spread throughout western North America.Native Americans quickly adopted the horse as a primary means of transportation. Interestingly, in light of the horse's prehistoric existence in the Americas, many Indian myths and stories about the arrival of horses claimed that "the grass remembered" them. ["Seeds of Change." Corpus Christi Museum, Science and History educational resources. Accessed June 1, 2007 at http://www.ccmuseumedres.com/tour.php?action=details&record=37] Horses replaced the dog as a
travois puller and greatly improved success in battles, trade, and hunts, particularly buffalo hunts.Starting in the colonial era and continuing with the westward expansion of the 1800s, horses belonging to explorers, traders and settlers that escaped or were purposely released joined the gene pool of Spanish-descended herds. It was also common practice for western
rancher s to release their horses to locateforage for themselves in the winter and then recapture them, as well as any additional Mustangs, in the spring. Some ranchers also attempted to "improve" wild herds by shooting the dominant stallions and replacing them with pedigreed animals.By 1900 North America had an estimated two million free-roaming horses. Since 1900, the Mustang population has been reduced drastically. Mustangs were viewed as a resource that could be captured and used or sold (especially for
military use) orslaughter ed for food, especially pet food. The controversial practice of mustanging was dramatized in the John Huston film "The Misfits," and the abuses linked to certain capture methods, including hunting from airplanes and poisoning, led to the first federal wild free-roaming horse protection law in 1959. [ [http://www.wildhorsepreservation.com/resources/annie_act.html Wild Horse Annie Act] ] Protection was increased further by theWild Free-Roaming Horse and Burro Act of 1971 . [ [http://www.house.gov/apps/list/press/ii00_democrats/rahallwhbbkd.pdf "Background Information on HR297"] ]Mustangs today
Today, free-roaming horses are protected under United States law, but have disappeared from several states where there were once established populations. [ [http://www.wildhorsepreservation.com/pdf/National.pdf National Summary, FY2007 ] ] A few hundred free-roaming horses survive in
Alberta andBritish Columbia . The BLM considers 27,000 individuals a manageable number, but the feral Mustang population currently exceeds 33,000. [http://www.cnn.com/2008/US/07/07/wild.horses.euthanasia.ap/index.html "Plan to kill wild horses runs into trouble>" "Associated Press," July 7, 2008] ] More than half of all Mustangs in North America are found inNevada (which features the horses on itsState Quarter in commemoration of this), with other significant populations inMontana , Wyoming andOregon . [ [http://www.wildhorsepreservation.com/pdf/National.pdf National Summary, FY2007 ] ] Another 30,000 horses are in holding facilities.Genetics
Historically, many of the Indian tribes bred their horses carefully to improve them for their purposes. Among the most capable horse-breeding people of North America were the
Comanche , theShoshoni , and theNez Perce . The last in particular became master horse breeders, and developed one of the first truly American breeds: theAppaloosa . Most other tribes did not practice extensive amounts of selective breeding, though they sought out desirable horses through capture, trade and theft, and quickly traded away or otherwise eliminated those with undesirable traits.Fact|date=June 2008In some modern mustang herds there is clear evidence of other domesticated horse breeds having become intermixed with feral herds. Some herds show the signs of the introduction of
Thoroughbred or other light racehorse-types into herds, a process that also led in part to the creation of theAmerican Quarter Horse .Fact|date=June 2008 Other herds show signs of the intermixing of heavydraft horse breeds turned loose in an attempt to create work horses. Other, more isolated herds, retain a strong influence of original Spanish stock.Some breeders of domestic horsesWho|date=May 2007 consider the Mustang herds of the west to be inbred and of inferior quality. However, supporters of the Mustang argue that the animals are merely small due to their harsh living conditions and that natural selection has eliminated many traits that lead to weakness or inferiority. Some mustang supportersWho|date=May 2007 also maintain that some "inbreeding" actually concentrates the traits of hardiness and durability, making the mustang a valuable genetic resource. Regardless of these debates, the Mustang of the modern west has several different breeding populations today which are genetically isolated from one another and thus have distinct traits traceable to particular herds. These herds vary in the degree to which they can be traced to original
Iberian horse s. Some contain a greater genetic mixture of ranch stock and more recent breed releases, others are relatively unchanged from the original Iberian stock. Fact|date=June 2008Land use controversies
Controversy surrounds the presence of
feral Mustang herds. Supporters argue that Mustangs are part of the natural heritage of theAmerican West , whose history predates modern land use practices, and thus the animals have an inherent right of inhabitation. [http://www.wildhorsepreservation.org The American Wild Horse Preservation Campaign] However, other people remain vehemently opposed to their presence, arguing that the animals degraderangeland and compete with livestock and wild species for forage. ["see, e.g." [http://www.wildhorsepreservation.com/resources/nas_report.html National Academy of Sciences Report, 1982]
[http://www.wildhorsepreservation.com/resources/gao_1991.html General Accounting Office Report, 1991] ]The debate as to what degree Mustangs and cattle compete for forage is multifaceted. One group of opponents, primarily cattle and sheep ranchers and those who depend on the livestock industry, argue essentially that
feral horse s degrade rangeland and compete with private livestock for public land forage. [ [http://www.igha.org/BLM8.html Bellisle, Martha. "Legislative battle brews over Nevada's wild horses" "Associated press" reprinted at I.G.H.A. / HorseAid's Bureau of Land Management News. Web site accessed May 11, 2007] ] The environmentalist community is split over the position of the Mustang within the North Americanecosystem . This debate centers on the potential classification of Mustangs as either anintroduced species such as cattle, or as a reintroduced native species due to the prehistoric presence of horses in North America, albeit with a gap of thousands of years between their extinction and reintroduction from European stock. [ [http://www.wildhorsepreservation.com/resources/native.html "Wild Horses as Native North American Wildlife"] Jay F. Kirkpatrick, Ph.D. and Patricia M. Fazio ]Researchers note that most current Mustang herds live in arid areas which cattle cannot fully utilize due to the lack of water sources. Horses are better adapted by
evolution to such climates. [ [http://www.wildhorsepreservation.com/resources/ecosystem.html Wild Horses and the Ecosystem] ] ; they may range nine times as far from water sources as cattle, traveling as much as 50 miles a day.Budiansky, Stephen. "The Nature of Horses." Free Press, 1997. ISBN 0-684-82768-9] This allows them to utilize areas not grazed by cattle. In addition, horses are "hindgut fermenters ," meaning that they digest nutrients by means of thececum rather than by a multi-chambered stomach. In practical effect, horses can obtain adequate nutrition from poorer forage than can cattle, surviving in areas where cattle will starve.Management and adoption
The
Bureau of Land Management (BLM) is tasked with protecting, managing, and controlling wild horses and burros under the authority of the 1971 Wild Free-Roaming Horses and Burros Act to ensure that healthy herds thrive on healthy rangelands and as multiple-use mission under the 1976Federal Land Policy and Management Act . Under the 1971 Act, shooting or poisoning Mustangs in the wild is illegal, and doing so can be prosecuted as a criminal felony.Healthy adult Mustangs have few natural predators aside from
mountain lion s,cite web |url=http://wf2dnvr2.webfeat.org/|title=Influence of Predation by Mountain Lions on Numbers and Survivorship of a Feral Horse Population|author=John W. Turner, Jr. and Michael L. Morrison|accessdate=2008-08-29 |date=2008 |publisher=The Southwestern Naturalist Vol. 46, No.2 pp. 183-190 ] and their herd sizes can multiply rapidly. To maintain population balance, (or, some argue, to make room for cattle [ [http://www.wildhorsepreservation.com/resources/study.html On BLM's wild horse management practices] ] ) one of the BLM’s key responsibilities under the 1971 law is to determine an appropriate management level (AML) of wild horses and burros in areas of publicrangeland s dedicated specifically for them. Control of the population to within AML is achieved through a capture program.Most horses that are captured are offered for adoption to individuals or groups willing and able to provide humane, long-term care after payment of an adoption fee that ranges from $25 to $125. [ [http://www.wildhorsepreservation.com/testimonials.html Wild Horse Preservation Campaign, Round-up testimonials] ] In order to prevent the later sale of mustangs as horse meat, adopted mustangs are still protected under the Act, and cannot be sold in the first year except when certain very specific criteria are met.
Because there is a much larger pool of captured horses than of prospective adoptive owners, in January 2005, a controversial amendment was attached to an
appropriation bill before theUnited States Congress by former SenatorConrad Burns , dubbed the "Burns rider." [ [http://www.wildhorsepreservation.com/resources/burns_story.html The Story Behind the Burns Amendment] ] This modified the adoption program to allow the sale (with the result usually being slaughter) of captured horses that are "more than 10 years of age", or that were "offered unsuccessfully for adoption at least three times." [ [http://www.wildhorsepreservation.com/resources/burns_amend.html Burns amendment.] ] In the110th United States Congress , legislation was introduced to have the rider repealed and the original language restored. [ [http://www.awionline.org/legislation/wild_horses/index.htm "Wild Horse and Burro Protection" "Animal Welfare Institute, Government and Legal Affairs."] Web page accessed June 24, 2008] The matter passed the House of Representatives and as of mid-2008 still awaits action in the Senate. [ [http://thomas.loc.gov/cgi-bin/bdquery/z?d110:H.R.249: Library of Congress THOMAS bill status for H.R. 249.] Accessed June 24, 2008] At present, with about 30,000 Mustangs in holding facilities, the BLM has, for the first time in public, considered euthanasia as a possible solution to overpopulation.ee also
