Range and Conservation

Main article: List of grey wolf populations by country See also: History of wolves in Yellowstone, Wolves in Great Britain, and Wolves in Ireland

The gray wolf was once the world's most widely distributed mammal, after humans and lions, living throughout the northern hemisphere north of 15°N latitude in North America and 12°N in India. Deliberate human persecution has reduced the species' range to about one third, due to livestock predation and fear over attacks on humans. The species is now extinct in much of Western Europe, in Mexico and much of the USA. In modern times, the gray wolf occurs mostly in wilderness and remote areas, particularly in Canada, Alaska and northern USA, Europe, and Asia from about 75°N to 12°N.

Wolf population declines have been arrested since the 1970s, and have fostered recolonization and reintroduction in parts of its former range, due to legal protection, changes in land-use and rural human population shifts to cities. Competition with humans for livestock and game species, concerns over the danger posed by wolves to people, and habitat fragmentation pose a continued threat to the species. Despite these threats, the gray wolf's relatively widespread range and stable population means that the species is not threatened at a global level, and is therefore classified by the IUCN as Least Concern.

Famous quotes containing the words range and, range and/or conservation:

    “During the cattle drives, Texas cowboy music came into national significance. Its practical purpose is well known—it was used primarily to keep the herds quiet at night, for often a ballad sung loudly and continuously enough might prevent a stampede. However, the cowboy also sang because he liked to sing.... In this music of the range and trail is “the grayness of the prairies, the mournful minor note of a Texas norther, and a rhythm that fits the gait of the cowboy’s pony.””
    —Administration in the State of Texa, U.S. public relief program (1935-1943)

    “Viewed freely, the English language is the accretion and growth of every dialect, race, and range of time, and is both the free and compacted composition of all.”
    —Walt Whitman (1819–1892)

    “A country grows in history not only because of the heroism of its troops on the field of battle, it grows also when it turns to justice and to right for the conservation of its interests.”
    —Aristide Briand (1862–1932)
