In agriculture , grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to free range (roam around) and consume wild vegetations in order to convert the otherwise indigestible (by human gut ) cellulose within grass and other forages into meat , milk , wool and other animal products , often on land that is unsuitable for arable farming .

114-424: A grazing period. Longer rotations are found in ley farming , alternating arable and fodder crops; in rest rotation, deferred rotation, and mob grazing, giving grasses a longer time to recover or leaving land fallow. Patch-burn sets up a rotation of fresh grass after burning with two years of rest. Conservation grazing proposes to use grazing animals to improve the biodiversity of a site. Grazing has existed since
152-546: A short period of time. Conservation grazing is the use of grazing animals to help improve the biodiversity of a site. Due to their hardy nature, rare and native breeds are often used in conservation grazing. In some cases, to re-establish traditional hay meadows, cattle such as the English Longhorn and Highland are used to provide grazing. A form of rotational grazing using as many small paddocks as fencing allows, said to be more sustainable. Mob grazing
190-450: A similar number in other zones, grazing livestock is the only possible source of livelihood." Grazing management has two overall goals: A proper land use and grazing management technique balances It does this by allowing sufficient recovery periods for regrowth. Producers can keep a low density on a pasture, so as not to overgraze. Controlled burning of the land can help in the regrowth of plants. Although grazing can be problematic for
228-482: A system of checks and balances, and allowing higher plant biodiversity. In Europe heathland is a cultural landscape which requires grazing by cattle, sheep or other grazers to be maintained. An author of the Food and Agriculture Organization (FAO) report Livestock's Long Shadow , stated in an interview: Grazing occupies 26 percent of Earth's terrestrial surface ... feed crop production requires about
266-552: A third of all arable land ... Expansion of grazing land for livestock is also a leading cause of deforestation, especially in Latin America... In the Amazon basin alone, about 70 percent of previously forested land is used as pasture, while feed crops cover a large part of the remainder. Much grazing land has resulted from a process of clearance or drainage of other habitats such as woodland or wetland . According to
304-492: Is a system, said to be more sustainable, invented in 2002; it uses very large herds on land left fallow longer than usual. Many ecological effects derive from grazing, which may be positive or negative. Negative effects of grazing may include overgrazing , increased soil erosion , compaction and degradation, deforestation , biodiversity loss , and adverse water quality impacts from run-off . Sometimes grazers can have beneficial environmental effects such as improving
342-648: Is allowed access to the same grazing area throughout the year. Seasonal grazing incorporates "grazing animals on a particular area for only part of the year". This allows the land that is not being grazed to rest and allow for new forage to grow. Rotational grazing "involves dividing the range into several pastures and then grazing each in sequence throughout the grazing period". Utilizing rotational grazing can improve livestock distribution while incorporating rest period for new forage. In ley farming, pastures are not permanently planted, but alternated between fodder crops and arable crops. Rest rotation grazing "divides
380-552: Is the major cause of degraded riparian habitat on federal rangelands". A 2013 FAO report estimated livestock were responsible for 14.5% of anthropogenic greenhouse gas emissions . Grazing is common in New Zealand ; in 2004, methane and nitrous oxide from agriculture made up somewhat less than half of New Zealand's greenhouse gas emissions, of which most is attributable to livestock . A 2008 United States Environmental Protection Agency report on emissions found agriculture
418-495: The Bolivar Waste Water Treatment Plant at Bolivar , 6 km (3.7 mi) to the north, in 1966. The Islington sewage farm was subsequently closed and the land fell into disuse. The new industrial suburb of Regency Park was created on the site. From 1975 to 1981 parts of the former sewage farm were subdivided and sold off by the state government. The 4.5-acre (1.8 ha) former residence of

#1732790778000456-716: The City of Enfield gave the Enfield & Districts Historical Society the Sunnybrae property to house a museum celebrating local history. The museum was officially opened in June 1995. In 2001, the society built the Sunnybrae Farm Federation Pavilion with the assistance of a $ 28,000 Commonwealth grant. The society conducted open days and other public activities from 2002 to 2008. The historical society
494-541: The beginning of agriculture ; sheep and goats were domesticated by nomads before the first permanent settlements were constructed around 7000 BC, enabling cattle and pigs to be kept. Livestock grazing contributes to many negative effects on the environment, including deforestation , extinction of native wildlife, pollution of streams and rivers, overgrazing , soil degradation , ecological disturbance , desertification , and ecosystem stability . Sheep, goats, cattle, and pigs were domesticated early in
532-539: The history of agriculture . Sheep were domesticated first, soon followed by goats; both species were suitable for nomadic peoples. Cattle and pigs were domesticated somewhat later, around 7000 BC, once people started to live in fixed settlements. In America, livestock were grazed on public land from the Civil War . The Taylor Grazing Act of 1934 was enacted after the Great Depression to regulate
570-457: The accumulation of litter ( organic matter ) in some seasons and areas, but can also increase it, which may help to combat soil erosion . This acts as nutrition for insects and organisms found within the soil. These organisms "aid in carbon sequestration and water filtration". When grass is grazed, dead grass and litter are reduced which is advantageous for birds such as waterfowl . Grazing can increase biodiversity . Without grazing, many of
608-401: The bison–fire relationship on a large landscape scale of 30,000 acres (12,000 ha). In the grazed heathland of Devon , the periodic burning is known as swailing. Riparian area grazing is intended to improve wildlife and their habitats. It uses fencing to keep livestock off ranges near streams or water areas until after wildlife or waterfowl periods, or to limit the amount of grazing to
646-536: The ecosystem, well-managed grazing techniques can reverse damage and improve the land. On commons in England and Wales, rights of pasture (grassland grazing) and pannage (forest grazing) for each commoner are tightly defined by number and type of animal, and by the time of year when certain rights can be exercised. For example, the occupier of a particular cottage might be allowed to graze fifteen cattle, four horses , ponies or donkeys , and fifty geese , while
684-487: The heavy grazing. This technique results in a diversity of habitats that different prairie plants and birds can utilize—mimicking the effects of the pre-historical relationship between bison and fire, whereby bison heavily graze one area and other areas have opportunity to rest, based on the concept of pyric herbivory . The Tallgrass Prairie Preserve in northeastern Oklahoma has been patch-burn grazed with bison herds for over ten years. These efforts have effectively restored

760-486: The numbers allowed for their neighbours would probably be different. On some commons (such as the New Forest and adjoining commons), the rights are not limited by numbers, and instead a 'marking fee' is paid each year for each animal 'turned out'. However, if excessive use was made of the common, for example, in overgrazing, a common would be 'stinted'; that is, a limit would be put on the number of animals each commoner
798-410: The official residence of the sewage farm's manager. In addition to the manager's residence, the historic complex also includes "Dairymen's Quarters, Cheese Room and Cellars, Stables, Cow Shed and Smoke House". It was only used for dairying and cheese production in 1882 to 1884, but continued to be used for depasturing stock and vegetable and fruit production irrigated by the processed sewage. In 1990

#1732790778000836-644: The opinion of the Center for Biological Diversity , extensive grazing of livestock in the arid lands of the southwestern United States has many negative impacts on the local biodiversity there. Cattle destroy native vegetation, damage soils and stream banks, and contaminate waterways with fecal waste. After decades of livestock grazing, once-lush streams and riparian forests have been reduced to flat, dry wastelands; once-rich topsoil has been turned to dust, causing soil erosion, stream sedimentation and wholesale elimination of some aquatic habitats In arid climates such as
874-478: The period when no grazing occurs. Patch-burn grazing burns a third of a pasture each year, no matter the size of the pasture. This burned patch attracts grazers (cattle or bison ) that graze the area heavily because of the fresh grasses that grow as a result. The other patches receive little to no grazing. During the next two years the next two patches are burned consecutively, then the cycle begins anew. In this way, patches receive two years of rest and recovery from
912-539: The purpose of constructing the Islington Sewage Farm. The sewage farm commenced operation in 1881. In 1948, a concrete watercourse was extended to North Arm Creek (Port River) and the post-war population boom saw the sewage farm overloaded and raw sewerage diverted to the North Arm Creek. Plans for a new sewerage works for Adelaide commenced in 1960 and the treatment of sewerage was relocated to
950-424: The range into at least four pastures. One pasture remains rested throughout the year and grazing is rotated amongst the residual pastures." This grazing system can be especially beneficial when using sensitive grass that requires time for rest and regrowth. Deferred rotation "involves at least two pastures with one not grazed until after seed-set". By using deferred rotation, grasses can achieve maximum growth during
988-422: The removal of wild grazing animals), or by other human disturbance. Conservation grazing is the use of grazers to manage such habitats, often to replicate the ecological effects of the wild relatives of domestic livestock , or those of other species now absent or extinct. Grazer urine and faeces "recycle nitrogen, phosphorus, potassium and other plant nutrients and return them to the soil". Grazing can reduce
1026-415: The same grasses grow, for example brome and bluegrass , consequently producing a monoculture . The ecosystems of North American tallgrass prairies are controlled to a large extent by nitrogen availability, which is itself controlled by interactions between fires and grazing by large herbivores. Fires in spring enhance growth of certain grasses, and herbivores preferentially graze these grasses, producing
1064-442: The sewage farm manager, Sunnybrae Farm, was preserved and in 1981 was transferred to the City of Enfield and declared a Historic Conservation and Recreation Centre. The old farm buildings at Sunnybrae were restored by history enthusiasts in partnership with the council. The site now houses a function centre and includes a museum originally created by the local historical society. The 3,500-square-metre (38,000 sq ft) site of

In some habitats, appropriate levels of grazing may be effective in restoring or maintaining native grass and herb diversity in rangeland that has been disturbed by overgrazing, lack of grazing (such as by
1140-621: The southwestern United States, livestock grazing has severely degraded riparian areas , the wetland environment adjacent to rivers or streams. The Environmental Protection Agency states that agriculture has a greater impact on stream and river contamination than any other nonpoint source . Improper grazing of riparian areas can contribute to nonpoint source pollution of riparian areas. Riparian zones in arid and semiarid environments have been called biodiversity hotspots . The water, higher biomass , favorable microclimate and periodic flood events together produce higher biological diversity than in
1178-399: The straining shed about 400 m (1,300 ft) southeast of Sunnybrae Farm near Pedder Crescent was also preserved. Sunnybrae Farm Complex ( 34°52′16″S 138°34′30″E / 34.871°S 138.575°E / -34.871; 138.575 ( Sunnybrae Farm Complex ) ) is a heritage-listed site in Regency Park, South Australia.

1216-709: The surrounding uplands. In 1990, "according to the Arizona state park department, over 90% of the original riparian zones of Arizona and New Mexico are gone". A 1988 report of the Government Accountability Office estimated that 90% of the 5,300 miles of riparian habitat managed by the Bureau of Land Management in Colorado was in an unsatisfactory condition, as was 80% of Idaho 's riparian zones, concluding that "poorly managed livestock grazing
1254-463: The use of public land for grazing purposes. According to a report by the Food and Agriculture Organization , about 60% of the world's grassland (just less than half of the world's usable surface) is covered by grazing systems. It states that "Grazing systems supply about 9 percent of the world's production of beef and about 30 percent of the world's production of sheep and goat meat . For an estimated 100 million people in arid areas , and probably
1292-473: Was a sewerage treatment facility located at Tam O'Shanter Belt/Islington (now Regency Park ) in South Australia, which operated from 1881 until 1966. According to a 1996 heritage survey by the City of Enfield Islington Sewage Farm was claimed to be Australia's earliest "water borne waste disposal treatment system". In 1879 land that is now Regency Park was acquired by the City of Adelaide for
1330-414: Was allowed to graze. These regulations were responsive to demographic and economic pressure. Thus, rather than let a common become degraded, access was restricted even further. Ranchers and range science researchers have developed grazing systems to improve sustainable forage production for livestock. These can be contrasted with intensive animal farming on feedlots. With continuous grazing, livestock
1368-585: Was dissolved in July 2012 and the property changed into private hands. It became known as Sunnybrae Estate, a commercially-owned function centre. The straining shed of the sewage farm was preserved from the 1970s land sale. As such the Islington Sewage Farm Straining Shed ( 34°52′26″S 138°34′44″E / 34.874°S 138.579°E / -34.874; 138.579 ( Islington Sewage Farm Straining Shed ) )
1406-464: Was responsible for 6% of total United States greenhouse gas emissions in 2006. This included rice production, enteric fermentation in domestic livestock, livestock manure management, and agricultural soil management , but omitted some things that might be attributable to agriculture. Studies comparing the methane emissions from grazing and feedlot cattle concluded that grass-fed cattle produce much more methane than grain-fed cattle. One study in
1444-582: Was state heritage-listed in 1984 because it represents "part of a comprehensive waste treatment process of the late 19th century." The building is also an example of how seemingly basic public infrastructure of the era was designed and built to be visually eminent and symbolic of civic pride. It is sited about 400 m (1,300 ft) southeast of Sunnybrae Farm near Pedder Crescent in view of Regency Road . Depasturing Farmers may employ many different strategies of grazing for optimum production : grazing may be continuous, seasonal, or rotational within
