Open range

In the Western United States and Canada, open range is rangeland where cattle roam freely regardless of land ownership. Where there are "open range" laws, those wanting to keep animals off their property must erect a fence to keep animals out; this applies to public roads as well. Land in open range that is designated as part of a "herd district" reverses liabilities, requiring an animal's owner to fence it in or otherwise keep it on the person's own property. Most eastern states and jurisdictions in Canada require owners to fence in or herd their livestock. History and practice The Western open-range tradition originated from the early practice of unregulated grazing of livestock in the newly acquired western territories of the United States and Canada. These practices were eventually codified in the laws of many Western US states as they developed written statutes. Over time, as the Western lands became more populated and more developed (through railroads, mining, farming, etc.), open-range laws began to be challenged and were significantly curtailed, though they still exist in certain areas of most Western US states and Canadian provinces. Open-range conditions existed in Western Canada prior to the 1889 amendments of the Dominion Lands Act, which prohibited cattle from grazing on unleased land, though the practice did not disappear immediately. Open-range management has also been practiced in other areas, including the Caribbean and some Eastern US states, such as South Carolina during the colonial period. The practice was also widespread in Mexico, and some argue that the Mexican tradition may have been the predecessor to open-range practices in the American West, much of which was part of Mexico prior to the 1840s. American ranchers borrowed many other cattle-raising techniques from Mexico.
