However, wetlands can also be a significant source of methane emissions due to anaerobic decomposition of soaked detritus , and some are also emitters of nitrous oxide . Humans are disturbing and damaging wetlands in many ways, including oil and gas extraction , building infrastructure, overgrazing of livestock , overfishing , alteration of wetlands including dredging and draining, nutrient pollution , and water pollution . Wetlands are more threatened by environmental degradation than any other ecosystem on Earth, according to

1122-1248: A polar climate, wetland temperatures can be as low as −50 °C (−58 °F). Peatlands in arctic and subarctic regions insulate the permafrost , thus delaying or preventing its thawing during summer, as well as inducing its formation. The amount of precipitation a wetland receives varies widely according to its area. Wetlands in Wales , Scotland , and western Ireland typically receive about 1,500 mm (59 in) per year. In some places in Southeast Asia , where heavy rains occur, they can receive up to 10,000 mm (390 in). In some drier regions, wetlands exist where as little as 180 mm (7.1 in) precipitation occurs each year. Temporal variation: Surface flow may occur in some segments, with subsurface flow in other segments. Wetlands vary widely due to local and regional differences in topography , hydrology , vegetation , and other factors, including human involvement. Other important factors include fertility, natural disturbance, competition, herbivory , burial and salinity. When peat accumulates, bogs and fens arise. The most important factor producing wetlands

1224-540: A portion of the overall water cycle, which also includes atmospheric water (precipitation) and groundwater . Many wetlands are directly linked to groundwater and they can be a crucial regulator of both the quantity and quality of water found below the ground. Wetlands that have permeable substrates like limestone or occur in areas with highly variable and fluctuating water tables have especially important roles in groundwater replenishment or water recharge. Substrates that are porous allow water to filter down through

1326-422: A strong influence on wetland water chemistry, particularly in coastal wetlands and in arid and semiarid regions with large precipitation deficits. Natural salinity is regulated by interactions between ground and surface water, which may be influenced by human activity. Carbon is the major nutrient cycled within wetlands. Most nutrients, such as sulfur , phosphorus , carbon , and nitrogen are found within

This population is the second-most highly centralised in the nation after Western Australia , with more than 77% of South Australians living in

1632-410: A unique kind of wetland where lush plant growth and slow decay of dead plants (under anoxic conditions) results in organic peat accumulating; bogs, fens, and mires are different names for peatlands. Variations of names for wetland systems: Some wetlands have localized names unique to a region such as the prairie potholes of North America's northern plain, pocosins , Carolina bays and baygalls of

1734-508: A wetland is "an ecosystem that arises when inundation by water produces soils dominated by anaerobic and aerobic processes, which, in turn, forces the biota, particularly rooted plants, to adapt to flooding". Sometimes a precise legal definition of a wetland is required. The definition used for regulation by the United States government is: 'The term "wetlands" means those areas that are inundated or saturated by surface or ground water at

1836-422: A wetland system includes its plants ( flora ) and animals ( fauna ) and microbes (bacteria, fungi). The most important factor is the wetland's duration of flooding. Other important factors include fertility and salinity of the water or soils. The chemistry of water flowing into wetlands depends on the source of water, the geological material that it flows through and the nutrients discharged from organic matter in

1938-403: A wetland) affects hydro-periods (temporal fluctuations in water levels) by controlling the water balance and water storage within a wetland. Landscape characteristics control wetland hydrology and water chemistry. The O 2 and CO 2 concentrations of water depend upon temperature , atmospheric pressure and mixing with the air (from winds or water flows). Water chemistry within wetlands

2040-558: A whole. To replace these wetland ecosystem services , enormous amounts of money would need to be spent on water purification plants, dams, levees, and other hard infrastructure, and many of the services are impossible to replace. Floodplains and closed-depression wetlands can provide the functions of storage reservoirs and flood protection. The wetland system of floodplains is formed from major rivers downstream from their headwaters . "The floodplains of major rivers act as natural storage reservoirs, enabling excess water to spread out over

2142-577: A wide area, which reduces its depth and speed. Wetlands close to the headwaters of streams and rivers can slow down rainwater runoff and spring snowmelt so that it does not run straight off the land into water courses. This can help prevent sudden, damaging floods downstream." Notable river systems that produce wide floodplains include the Nile River , the Niger river inland delta, the Zambezi River flood plain,

Amphibians such as frogs and salamanders need both terrestrial and aquatic habitats in which to reproduce and feed. Because amphibians often inhabit depressional wetlands like prairie potholes and Carolina bays, the connectivity among these isolated wetlands is an important control of regional populations. While tadpoles feed on algae, adult frogs forage on insects. Frogs are sometimes used as an indicator of ecosystem health because their thin skin permits absorption of nutrients and toxins from

Depending on a wetland's geographic and topographic location, the functions it performs can support multiple ecosystem services , values, or benefits. United Nations Millennium Ecosystem Assessment and Ramsar Convention described wetlands as a whole to be of biosphere significance and societal importance in

7446-403: The lead over other Australian states for its commercialisation and commitment to renewable energy . It is now the leading producer of wind power in Australia. Renewable energy is a growing source of electricity in South Australia, and there is potential for growth from this particular industry of the state's economy. The Hornsdale Power Reserve is a bank of grid-connected batteries adjacent to

7548-456: The least amount of federal funding for its local road network of all states on a per capita and a per kilometre basis. During 2019-20: South Australia's gross state product (GSP) fell 1.4% in chain volume (real) terms (nationally, gross domestic product (GDP) fell 0.3%). South Australia came out of the COVID-19 recession better than the other Australian states, with the economy growing by 3.9% in

7650-656: The letters patent of the imperial government to create the colony. He was accountable only to the British Colonial Office , and thus democracy did not exist in the colony. A new body was created to advise the governor on the administration of South Australia in 1843 called the Legislative Council. It consisted of three representatives of the British Government and four colonists appointed by the governor. The governor retained total executive power. In 1851,

7752-534: The local government area of the Renmark Paringa Council . Renmark is a multicultural centre for the Riverland area. The river itself offers excellent spots for fishing , waterskiing and boating . The area is known for the cultivation of grapes , citrus fruits , tomatoes , vegetables , wheat and wool . Orange trees stretch for hectares as do vineyards and stone fruit orchards. Other industries include almond growing and pistachio nut cultivation. Renmark

7854-657: The new province. The Letters Patent , which used the enabling provisions of the South Australia Act 1834 to fix the boundaries of the Province of South Australia, provided that "nothing in those our Letters Patent shall affect or be construed to affect the rights of any Aboriginal Natives of the said Province to the actual occupation and enjoyment in their own Persons or in the Persons of their Descendants of any Lands therein now actually occupied or enjoyed by such Natives." Although

7956-519: The patent guaranteed land rights under force of law for the indigenous inhabitants, it was ignored by the South Australian Company authorities and squatters. Despite strong reference to the rights of the native population in the initial proclamation by the Governor, there were many conflicts and deaths in the Australian Frontier Wars in South Australia. Survey was required before settlement of

8058-832: The plants and animals controlled by the wetland hydrology are often additional components of the definitions. Wetlands can be tidal (inundated by tides) or non-tidal. The water in wetlands is either freshwater , brackish , saline , or alkaline . There are four main kinds of wetlands – marsh , swamp , bog , and fen (bogs and fens being types of peatlands or mires ). Some experts also recognize wet meadows and aquatic ecosystems as additional wetland types. Sub-types include mangrove forests , carrs , pocosins , floodplains , peatlands, vernal pools , sinks , and many others. The following three groups are used within Australia to classify wetland by type: Marine and coastal zone wetlands, inland wetlands and human-made wetlands. In

8160-470: The province, and the Colonization Commissioners for South Australia appointed William Light as the leader of its 'First Expedition', tasked with examining 1500 miles of the South Australian coastline and selecting the best site for the capital, and with then planning and surveying the site of the city into one-acre Town Sections and its surrounds into 134-acre Country Sections. Eager to commence

8262-466: The railway line across the bridge to Paringa was opened. It was later extended west as far as Barmera , and known as the Barmera railway line , but then closed in 1983 then the last scheduled train to cross the bridge was on 31 December 1990. Renmark has a number of heritage-listed sites, including: Renmark is located within the federal division of Barker , the state electoral district of Chaffey and

8364-429: The soil and underlying rock into aquifers which are the source of much of the world's drinking water . Wetlands can also act as recharge areas when the surrounding water table is low and as a discharge zone when it is high. Mangroves , coral reefs , salt marsh can help with shoreline stabilization and storm protection. Tidal and inter-tidal wetland systems protect and stabilize coastal zones. Coral reefs provide

8466-537: The soil of wetlands. Anaerobic and aerobic respiration in the soil influences the nutrient cycling of carbon, hydrogen, oxygen, and nitrogen, and the solubility of phosphorus thus contributing to the chemical variations in its water. Wetlands with low pH and saline conductivity may reflect the presence of acid sulfates and wetlands with average salinity levels can be heavily influenced by calcium or magnesium. Biogeochemical processes in wetlands are determined by soils with low redox potential. The life forms of

8568-412: The soils and plants at higher elevations. Plants and animals may vary within a wetland seasonally or in response to flood regimes. There are four main groups of hydrophytes that are found in wetland systems throughout the world. Submerged wetland vegetation can grow in saline and fresh-water conditions. Some species have underwater flowers, while others have long stems to allow the flowers to reach

8670-515: The sources of water include tidal wetlands , where the water source is ocean tides ); estuaries , water source is mixed tidal and river waters; floodplains , water source is excess water from overflowed rivers or lakes; and bogs and vernal ponds , water source is rainfall or meltwater . The world's largest wetlands include the Amazon River basin , the West Siberian Plain ,

8772-492: The south-east by Victoria , and to the south by the Great Australian Bight . The state comprises less than 8% of the Australian population and ranks fifth in population among the six states and two territories. The majority of its people reside in greater Metropolitan Adelaide. Most of the remainder are settled in fertile areas along the south-eastern coast and River Murray . The state's colonial origins are unique in Australia as

8874-406: The spatial and temporal dispersion, flow, and physio-chemical attributes of surface and ground waters. Sources of hydrological flows into wetlands are predominantly precipitation , surface water (saltwater or freshwater), and groundwater. Water flows out of wetlands by evapotranspiration , surface flows and tides , and subsurface water outflow. Hydrodynamics (the movement of water through and from

8976-538: The state has a Mediterranean climate , while the rest of the state has either an arid or semi-arid climate . South Australia's main temperature range is 29 °C (84 °F) in January and 15 °C (59 °F) in July. The highest maximum temperature ever recorded was 50.7 °C (123.3 °F) at Oodnadatta on 2 January 1960, which is the highest official temperature recorded in Australia. The lowest minimum temperature

9078-578: The state's upper house with the balance of power controlled by a variety of minor parties and independents. Local government in South Australia is established by the Constitution Act 1934 (SA), the Local Government Act 1999 (SA), and the Local Government (Elections) Act 1999 (SA). South Australia contains 68 councils and 6 Aboriginal and outback communities . Local councils, elected on

9180-709: The surface of the water. When trees and shrubs comprise much of the plant cover in saturated soils, those areas in most cases are called swamps . The upland boundary of swamps is determined partly by water levels. This can be affected by dams Some swamps can be dominated by a single species, such as silver maple swamps around the Great Lakes . Others, like those of the Amazon basin , have large numbers of different tree species. Other examples include cypress ( Taxodium ) and mangrove swamps. Many species of fish are highly dependent on wetland ecosystems. Seventy-five percent of

9282-490: The surface. Submerged species provide a food source for native fauna, habitat for invertebrates, and also possess filtration capabilities. Examples include seagrasses and eelgrass . Floating water plants or floating vegetation are usually small, like those in the Lemnoideae subfamily (duckweeds). Emergent vegetation like the cattails ( Typha spp.), sedges ( Carex spp.) and arrow arum ( Peltandra virginica ) rise above

9384-457: The surrounding environment resulting in increased extinction rates in unfavorable and polluted environmental conditions. Reptiles such as snakes , lizards , turtles , alligators and crocodiles are common in wetlands of some regions. In freshwater wetlands of the Southeastern US, alligators are common and a freshwater species of crocodile occurs in South Florida. The Florida Everglades

9486-440: The types of plants that live within them. Specifically, wetlands are characterized as having a water table that stands at or near the land surface for a long enough period each year to support aquatic plants . A more concise definition is a community composed of hydric soil and hydrophytes . Wetlands have also been described as ecotones , providing a transition between dry land and water bodies. Wetlands exist "...at

9588-520: The upper house, the Legislative Council, remained the exclusive domain of property owners until the Labor government of Don Dunstan managed to achieve reform of the chamber in 1973. Property qualifications were removed and the Council became a body elected via proportional representation by a single state-wide electorate. Since the following 1975 South Australian state election , no one party has had control of

9690-447: The world. Opal was first discovered near the town in 1915, and the town became the site of an opal rush, enticing immigrants from southern and eastern Europe in the aftermath of World War II . Higher education and research in Adelaide forms an important part of South Australia's economy. The South Australian Government and educational institutions have attempted to position Adelaide as Australia's education hub and have marketed it as

9792-522: Was excised for the town and irrigation project. Another possibility is the name of an early settler in the district, William Renny. Wool was shipped from "Renmark" in 1878, The first unambiguous use of the name (as "Renmark Flat") in newspapers was in November 1883. Captain Charles Sturt was the first European to pass through the area in January 1830, as he navigated the length of the Murray River from

9894-492: Was formally constituted as a penal colony. Although South Australia was constituted such that convicts could never be transported to the Province, some emancipated or escaped convicts or expirees made their own way there, both prior to 1836, or later, and may have constituted 1–2% of the early population. The plan for the province was that it would be an experiment in reform, addressing the problems perceived in British society. There

9996-550: Was founded. The guiding principle behind settlement was that of systematic colonisation , a theory espoused by Edward Gibbon Wakefield that was later employed by the New Zealand Company . The goal was to establish the province as a centre of civilisation for free immigrants, promising civil liberties and religious tolerance. Although its history has been marked by periods of economic hardship, South Australia has remained politically innovative and culturally vibrant. Today, it

10098-461: Was the first Australian colony not to have an official state religion, and the colony became attractive to people who had experienced religious discrimination, including Methodists and Unitarians . South Australia also had thousands of Prussian Old Lutheran immigrants, some of whom established their own form of Lutheranism. As a result, the Lutheran Church of Australia remains separate from

10200-470: Was to be religious freedom and no established religion. Sales of land to colonists created an Emigration Fund to pay the costs of transferring a poor young labouring population to South Australia. In early 1838 the colonists became concerned after it was reported that convicts who had escaped from the eastern states may make their way to South Australia. The South Australia Police was formed in April 1838 to protect

10302-559: Was upgraded to AAA by Standard & Poor's in September 2004 and to AAA by Moody's in November 2004, the highest credit ratings achievable by any company or sovereign. The state had previously lost these ratings in the State Bank collapse. However, in 2012 Standard & Poor's downgraded the state's credit rating to AA+ due to declining revenues, new spending initiatives and a weaker than expected budgetary outlook. South Australia receives

10404-769: Was −8.2 °C (17.2 °F) at Yongala on 20 July 1976. The region's overall dry weather is owed to the Australian High on the Great Australian Bight. As of 2016, South Australia had 746,105 people employed out of a total workforce of 806,593, giving an unemployment rate of 7.5%. South Australia's largest employment sector is health care and social assistance, making up 14.8% of the state's total employment, followed by retail (10.7%), education and training (8.6%), manufacturing (8%), and construction (7.6%). South Australia's economy relies on exports more than any other state in Australia. South Australia's credit rating
