96-545: De Mole River is a locality in the Australian state of South Australia located on the north coast of Kangaroo Island overlooking Investigator Strait about 175 kilometres (109 miles) south-west of the state capital of Adelaide . The locality’s boundaries were created in May 2002 for the “long established name” which is reported to be derived from the stream located within its boundaries. The principal land use within

192-668: A Learning City . The number of international students studying in Adelaide has increased rapidly in recent years to 30,726 in 2015, of which 1,824 were secondary school students. Foreign institutions have been attracted to set up campuses to increase its attractiveness as an education hub. Adelaide is the birthplace of three Nobel laureates, more than any other Australian city : physicist William Lawrence Bragg and pathologists Howard Florey and Robin Warren , all of whom completed secondary and tertiary education at St Peter's College and

288-506: A form of erosion that occur at the sides of gullies that cut into the peat; they sometimes also occur in isolation. Hags may result when flowing water cuts downwards into the peat and when fire or overgrazing exposes the peat surface. Once the peat is exposed in these ways, it is prone to further erosion by wind, water and livestock. The result is overhanging vegetation and peat. Hags are too steep and unstable for vegetation to establish itself, so they continue to erode unless restorative action

384-413: A four-yearly basis, are responsible for local roads and stormwater management, waste collection, planning and development, fire prevention and hazard management, dog and cat management and control, parking control, public health and food inspections, and other services for their local communities. Councils have the power to raise revenue for their activities, which is mostly achieved through "council rates",

480-496: A result of peat drainage, the organic carbon—which built over thousands of years and is normally underwater—is suddenly exposed to the air. It decomposes and turns into carbon dioxide (CO 2 ), which is released into the atmosphere. The global CO 2 emissions from drained peatlands have increased from 1,058 Mton in 1990 to 1,298 Mton in 2008 (a 20% increase). This increase has particularly taken place in developing countries, of which Indonesia , Malaysia and Papua New Guinea are

576-490: A small increase in carbon dioxide uptake, meaning that it contributes to the permafrost carbon feedback . Under 2 °C global warming , 0.7 million km of peatland permafrost could thaw, and with warming of +1.5 to 6 °C a cumulative 0.7 to 3 PgC of methane could be released as a result of permafrost peatland thaw by 2100. The forcing from these potential emissions would be approximately equivalent to 1% of projected anthropogenic emissions. One characteristic of peat

672-735: A tax based on property valuations. Council rates make up about 70% of council revenue, but account for less than 4% of total taxes paid by Australians. As at December 2021 the population of South Australia was 1,806,599. A majority of the state's population lives within Greater Adelaide 's metropolitan area which had an estimated population of 1,333,927 in June 2017. Other significant population centres include Mount Gambier (29,505), Victor Harbor - Goolwa (26,334), Whyalla (21,976), Murray Bridge (18,452), Port Lincoln (16,281), Port Pirie (14,267), and Port Augusta (13,957). At

768-662: A temporary settlement at Kingscote , Kangaroo Island , on 26 July 1836, five months before Adelaide 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

864-539: A tenth of the total permafrost area, and also a tenth (185 ± 66 Gt) of all permafrost carbon, equivalent to around half of the carbon stored in the atmosphere. Dry peat is a good insulator (with a thermal conductivity of around 0.25 Wm K ) and therefore plays an important role in protecting permafrost from thaw. The insulating effect of dry peat also makes it integral to unique permafrost landforms such as palsas and permafrost peat plateaus. Peatland permafrost thaw tends to result in an increase in methane emissions and

960-432: Is a state in the southern central part of Australia . With a total land area of 984,321 square kilometres (380,048 sq mi), it is the fourth-largest of Australia's states and territories by area, which includes some of the most arid parts of the continent, and with 1.8 million people it is the fifth-largest of the states and territories by population. This population is the second-most highly centralised in

1056-487: Is also reported that peat regrowth takes place only in 30–40% of peatlands. Centuries of burning and draining of peat by humans has released a significant amount of CO 2 into the atmosphere, and much peatland restoration is needed to help limit climate change . Peat forms when plant material does not fully decay in acidic and anaerobic conditions. It is composed mainly of wetland vegetation: principally bog plants including mosses , sedges and shrubs. As it accumulates,

1152-478: Is also the world's fourth-largest remaining copper deposit, and the world's fifth largest gold deposit. There was a proposal to vastly expand the operations of the mine, making it the largest open-cut mine in the world, but in 2012 the BHP Billiton board decided not to go ahead with it at that time due to then lower commodity prices. The remote town of Coober Pedy produces more opal than anywhere else in

1248-477: Is available in considerable quantities. It is burned to produce heat and electricity . Peat provides around 4% of Finland's annual energy production. Also, agricultural and forestry-drained peat bogs actively release more CO 2 annually than is released in peat energy production in Finland. The average regrowth rate of a single peat bog, however, is indeed slow, from 1,000 up to 5,000 years. Furthermore, it

1344-551: Is cut by hand and left to dry in the sun. In many countries, including Ireland and Scotland , peat was traditionally stacked to dry in rural areas and used for cooking and domestic heating. This tradition can be traced back to the Roman period. For industrial uses, companies may use pressure to extract water from the peat, which is soft and easily compressed. In Sweden, farmers use dried peat to absorb excrement from cattle that are wintered indoors. The most essential property of peat

1440-423: Is either fibric, hemic, or sapric. Fibric peats are the least decomposed and consist of intact fibre. Hemic peats are partially decomposed and sapric are the most decomposed. Phragmites peat are composed of reed grass, Phragmites australis , and other grasses. It is denser than many other types of peat. Engineers may describe a soil as peat which has a relatively high percentage of organic material. This soil

1536-712: Is estimated that in 1997, peat and forest fires in Indonesia released between 0.81 and 2.57 gigatonnes (0.89 and 2.83 billion short tons; 0.80 and 2.53 billion long tons) of carbon; equivalent to 13–40 percent of the amount released by global fossil fuel burning, and greater than the carbon uptake of the world's biosphere. These fires may be responsible for the acceleration in the increase in carbon dioxide levels since 1998. More than 100 peat fires in Kalimantan and East Sumatra have continued to burn since 1997; each year, these peat fires ignite new forest fires above

1632-602: Is flanked by the Southern Ocean , but official international consensus defines the Southern Ocean as extending north from the pole only to 60°S or 55°S, at least 17 degrees of latitude further south than the most southern point of South Australia. Thus the south coast is officially adjacent to the south-most portion of the Indian Ocean. See Southern Ocean: Existence and definitions . The southern part of

1728-603: Is known for its fine wine and numerous cultural festivals. The state's economy is dominated by the agricultural, manufacturing and mining industries. Evidence of human activity in South Australia dates back as far as 20,000 years, with flint mining activity and rock art in the Koonalda Cave on the Nullarbor Plain . In addition wooden spears and tools were made in an area now covered in peat bog in

1824-483: Is problematic because it exhibits poor consolidation properties—it cannot be easily compacted to serve as a stable foundation to support loads, such as roads or buildings. In a widely cited article, Joosten and Clarke (2002) described peatlands or mires (which they say are the same) as the most widespread of all wetland types in the world, representing 50 to 70% of global wetlands. They cover over 4 million square kilometres [1.5 million square miles] or 3% of

1920-506: Is retaining moisture in container soil when it is dry while preventing the excess water from killing roots when it is wet. Peat can store nutrients although it is not fertile itself—it is polyelectrolytic with a high ion-exchange capacity due to its oxidized lignin. Peat is discouraged as a soil amendment by the Royal Botanic Gardens, Kew , England, since 2003. While bark or coir -based peat-free potting soil mixes are on

2016-635: Is sometimes used in freshwater aquaria . It is seen most commonly in soft water or blackwater river systems such as those mimicking the Amazon River basin. In addition to being soft and therefore suitable for demersal (bottom-dwelling) species such as Corydoras catfish, peat is reported to have many other beneficial functions in freshwater aquaria. It softens water by acting as an ion exchanger ; it also contains substances that are beneficial for plants and fishes' reproductive health. Peat can prevent algae growth and kill microorganisms. Peat often stains

2112-769: Is taken. In June 2002, the United Nations Development Programme launched the Wetlands Ecosystem and Tropical Peat Swamp Forest Rehabilitation Project. This project was targeted to last for five years, and brings together the efforts of various non-government organisations. In November 2002, the International Peatland (formerly Peat) Society (IPS) and the International Mire Conservation Group (IMCG) published guidelines on

2208-560: Is the Mount Lofty - Flinders Ranges system, which extends north about 800 kilometres (500 mi) from Cape Jervis to the northern end of Lake Torrens . The highest point in the state is not in those ranges; Mount Woodroffe (1,435 metres (4,708 ft)) is in the Musgrave Ranges in the extreme northwest of the state. The south-western portion of the state consists of the sparsely inhabited Nullarbor Plain , fronted by

2304-565: Is the average depth of the boreal [northern] peatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO 2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon , which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. Peat is not a renewable source of energy , due to its extraction rate in industrialized countries far exceeding its slow regrowth rate of 1 mm (0.04 in) per year, and as it

2400-401: Is the bioaccumulation of metals concentrated in the peat. Accumulated mercury is of significant environmental concern. Large areas of organic wetland (peat) soils are currently drained for agriculture, forestry and peat extraction (i.e. through canals ). This process is taking place all over the world. This not only destroys the habitat of many species but also heavily fuels climate change. As

2496-407: Is the most efficient carbon sink on the planet , because peatland plants capture carbon dioxide (CO 2 ) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of 1.5 to 2.3 m [4.9 to 7.5 ft], which

2592-456: The "Wise Use of Mires and Peatlands – Backgrounds and Principles including a framework for decision-making" . This publication aims to develop mechanisms that can balance the conflicting demands on the global peatland heritage to ensure its wise use to meet the needs of humankind. In June 2008, the IPS published the book Peatlands and Climate Change , summarising the currently available knowledge on

Almonds , citrus and stone fruit are grown in the Riverland . Potatoes , onions and carrots are grown in the Murray Mallee region. Potatoes are grown on Kangaroo Island . South Australia produces more than half of all Australian wine, including almost 80% of Australia's premium wines. South Australia has

2784-800: The Dutch ship the Gulden Zeepaert , captained by François Thijssen , examined and mapped a section of the coastline as far east as the Nuyts Archipelago . Thijssen named the whole of the country eastward of the Leeuwin "Nuyts Land", after a distinguished passenger on board; the Hon. Pieter Nuyts , one of the Councillors of India . The coastline of South Australia was first mapped by Matthew Flinders and Nicolas Baudin in 1802, excepting

2880-819: The Falkland Islands and Indonesia ( Kalimantan [Sungai Putri, Danau Siawan, Sungai Tolak], Rasau Jaya ( West Kalimantan ) and Sumatra ). Indonesia has more tropical peatlands and mangrove forests than any other nation on earth, but Indonesia is losing wetlands by 100,000 hectares (250,000 acres) per year. A catalog of the peat research collection at the University of Minnesota Duluth provides references to research on worldwide peat and peatlands. About 7% of all peatlands have been exploited for agriculture and forestry . Under certain conditions, peat will turn into lignite coal over geologic periods of time. Peat can be used as fuel once dried. Traditionally, peat

The act stated that the land between 132° and 141° east longitude and from 26° south latitude to the southern ocean would be allotted to the intended colony, and it would be convict-free. In contrast to the rest of Australia, terra nullius did not apply to

3360-525: The University of Adelaide . Adelaide is home to research institutes, including the Royal Institution of Australia , established in 2009 as a counterpart to the two-hundred-year-old Royal Institution of Great Britain. Most of the research organisations are clustered in the Adelaide metropolitan area: South Australia is a constitutional monarchy with King Charles III as sovereign, and

The recovery was driven in part by growth in the agricultural sector, which increased its production by almost 24% thanks to the end of a drought. Wheat , barley , oats , rye , peas , beans , chickpeas , lentils and canola are grown in South Australia. Apples , pears , cherries and strawberries are grown in

3936-600: The City of Adelaide is currently located. The first immigrants arrived at Holdfast Bay (near the present day Glenelg ) in November 1836. The commencement of colonial government was proclaimed on 28 December 1836, now known as Proclamation Day . South Australia is the only Australian state to have never received British convicts. Another free settlement, Swan River colony was established in 1829 but Western Australia later sought convict labour, and in 1849 Western Australia

Peat Peatlands, particularly bogs , are the primary source of peat; although less common, other wetlands, including fens , pocosins and peat swamp forests , also deposit peat. Landscapes covered in peat are home to specific kinds of plants, including Sphagnum moss, ericaceous shrubs and sedges . Because organic matter accumulates over thousands of years, peat deposits provide records of past vegetation and climate by preserving plant remains, such as pollen. This allows

4128-597: The Imperial Parliament enacted the Australian Colonies Government Act , which allowed for the election of representatives to each of the colonial legislatures and the drafting of a constitution to properly create representative and responsible government in South Australia. Later that year, propertied male colonists were allowed to vote for 16 members on a new 24 seat Legislative Council. Eight members continued to be appointed by

According to mitochondrial DNA research, Aboriginal people reached Eyre Peninsula 49,000-45,000 years ago from both the east (clockwise, along the coast, from northern Australia) and the west (anti-clockwise). The first recorded European sighting of the South Australian coast was in 1627 when

4320-548: The West Siberian peatland. Palsa mires have a rich bird life and are an EU-red listed habitat, and in Canada riparian peat banks are used as maternity sites for polar bears. Natural peatlands also have many species of wild orchids and carnivorous plants. For more on biological communities, see wetland , bog or fen . Around half of the area of northern peatlands is permafrost -affected, and this area represents around

4416-522: The bogland remains constantly wet which helps promote peat production. Most modern peat bogs formed 12,000 years ago in high latitudes after the glaciers retreated at the end of the last ice age . Peat usually accumulates slowly at the rate of about a millimetre per year. The estimated carbon content is 415 gigatonnes (457 billion short tons) (northern peatlands), 50 Gt (55 billion short tons) ( tropical peatlands ) and 15 Gt (17 billion short tons) (South America). Peat material

4512-509: The border on the ground in the 1920s. In 1863, that part of New South Wales to the north of South Australia was annexed to South Australia, by letters patent, as the "Northern Territory of South Australia", which became shortened to the Northern Territory on 6 July 1863 . The Northern Territory was handed to the federal government in 1911 and became a separate territory. According to Australian maps, South Australia's south coast

4608-550: The capital of Moscow with a toxic smoke blanket . The situation remained critical until the end of August 2010. In June 2019, despite some forest fire prevention methods being put in place, peat fires in the Arctic emitted 50 megatonnes (55 million short tons; 49 million long tons) of CO 2 , which is equal to Sweden's total annual emissions. The peat fires are linked to climate change, as they are much more likely to occur nowadays due to this effect. Peat "hags" are

The Temperate Grassland of South Australia is situated to the east of Gulf St Vincent . The principal industries and exports of South Australia are wheat, wine and wool. More than half of Australia's wines are produced in the South Australian wine regions which principally include Barossa Valley , Clare Valley , McLaren Vale , Coonawarra ,

4800-477: The colony of New South Wales . Although the new colony included almost two-thirds of the continent, early settlements were all on the eastern coast and only a few intrepid explorers ventured this far west. It took more than forty years before any serious proposal to establish settlements in the south-western portion of New South Wales were put forward. On 15 August 1834, the British Parliament passed

4896-581: The community and enforce government regulations. Their principal role was to run the first temporary gaol, a two-room hut. The current flag of South Australia was adopted on 13 January 1904, and is a British blue ensign defaced with the state badge. The badge is described as a piping shrike with wings outstretched on a yellow disc. The state badge is believed to have been designed by Robert Craig of Adelaide's School of Design . The terrain consists largely of arid and semi-arid rangelands, with several low mountain ranges . The most important (but not tallest)

4992-428: The concept of peat archives, a phrase coined by influential peatland scientist Harry Godwin in 1981. In a peat profile there is a fossilized record of changes over time in the vegetation, pollen, spores, animals (from microscopic to the giant elk), and archaeological remains that have been deposited in place, as well as pollen, spores and particles brought in by wind and weather. These remains are collectively termed

In 1897 Catherine Helen Spence was the first woman in Australia to be a candidate for political office when she was nominated to be one of South Australia's delegates to the conventions that drafted the constitution. South Australia became an original state of the Commonwealth of Australia on 1 January 1901. Although the lower house had universal suffrage,

5376-501: The government is the party or coalition that exerts a majority in the House of Assembly. The Legislative Council remained a predominantly conservative chamber elected by property owners. Women's suffrage in Australia took a leap forward – enacted in 1895 and taking effect from the 1896 colonial election , South Australia was the first government in Australia and only the second in the world after New Zealand to allow women to vote, and

5472-539: The governor. The main responsibility of this body was to draft a constitution for South Australia. The body drafted the most democratic constitution ever seen in the British Empire and provided for universal manhood suffrage . It created the bicameral Parliament of South Australia . For the first time in the colony, the executive was elected by the people, and the colony used the Westminster system , where

5568-603: The ground. In North America, peat fires can occur during severe droughts throughout their occurrence, from boreal forests in Canada to swamps and fens in the subtropical southern Florida Everglades . Once a fire has burnt through the area, hollows in the peat are burnt out, and hummocks are desiccated but can contribute to Sphagnum recolonization. In the summer of 2010, an unusually high heat wave of up to 40 °C (104 °F) ignited large deposits of peat in Central Russia, burning thousands of houses and covering

These ecosystems are characterized by the unique ability to accumulate and store dead organic matter from Sphagnum and many other non-moss species, as peat, under conditions of almost permanent water saturation. Peatlands are adapted to the extreme conditions of high water and low oxygen content, of toxic elements and low availability of plant nutrients. Their water chemistry varies from alkaline to acidic. Peatlands occur on all continents, from

The characteristics of some bog plants actively promote bog formation. For example, sphagnum mosses actively secrete tannins , which preserve organic material. Sphagnum also have special water-retaining cells, known as hyaline cells, which can release water ensuring

6912-683: The potential human impacts on the biogeochemical cycle of mercury, for example. Over the years, different dating models and technologies for measuring date sediments and peat profiles accumulated over the last 100–150 years, have been used, including the widely used vertical distribution of 210Pb, the inductively coupled plasma mass spectrometry (ICP-SMS), and more recently the initial penetration (IP). Naturally mummified human bodies, often called " bog bodies " have been found in various places in Scotland, England, Ireland, and especially northern Germany and Denmark. They are almost perfectly preserved by

7008-441: The presence of a heat source (e.g., a wildfire penetrating the subsurface), it smoulders. These smouldering fires can burn undetected for very long periods of time (months, years, and even centuries) propagating in a creeping fashion through the underground peat layer. Despite the damage that the burning of raw peat can cause, bogs are naturally subject to wildfires and depend on the wildfires to keep woody competition from lowering

7104-481: 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

7200-545: The reconstruction of past environments and the study of land-use changes. Peat is used by gardeners and for horticulture in certain parts of the world, but this is being banned in some places. By volume, there are about 4 trillion cubic metres of peat in the world. Over time, the formation of peat is often the first step in the geological formation of fossil fuels such as coal , particularly low-grade coal such as lignite . The peatland ecosystem covers 3.7 million square kilometres (1.4 million square miles) and

7296-614: The rewetting of peatlands and revegetation of native species. This acts to mitigate carbon release in the short term before the new growth of vegetation provides a new source of organic litter to fuel the peat formation in the long term. UNEP is supporting peatland restoration in Indonesia. Latvia has been the biggest exporter of peat in the world by volume, providing more than 19.9% of the world's volume, followed only by Canada with 13% in 2022. In 2020, Latvia exported 1.97 million tons of peat, followed by Germany with 1.5 and Canada with 1.42 million tons. Nevertheless, although first in

7392-625: The rise, particularly in the UK, peat is still used as raw material for horticulture in some other European countries, Canada, as well as parts of the United States. Peatland can also be an essential source of drinking water , providing nearly 4% of all potable water stored in reservoirs . In the UK, 43% of the population receives drinking water sourced from peatlands, with the number climbing to 68% in Ireland. Catchments containing peatlands are

7488-628: The same bog about 60 metres (200 ft) from the Tollund Man. She is believed to have lived during the late 3rd century BC and was a ritual sacrifice. In the Bronze and Iron Ages, people used peat bogs for rituals to nature gods and spirits. The distinctive ecological conditions of peat wetlands provide a habitat for distinctive fauna and flora. For example, whooping cranes nest in North American peatlands, whilst Siberian cranes nest in

7584-534: The south-eastern coast and River Murray . The state's colonial origins are unique in Australia as a freely settled, planned British province , rather than as a convict settlement. Colonial government commenced on 28 December 1836, when the members of the council were sworn in near the Old Gum Tree . As with the rest of the continent, the region has a long history of human occupation by numerous tribes and languages. The South Australian Company established

7680-547: 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

7776-511: The state whilst 23% belong to the municipalities Bogs in Latvia are considered important habitats due to their ecological values, and up to 128,000 hectares, or 40% of the areas in the territory, are protected by environmental laws. The most famous national parks and reserves are the Ķemeri National Park , Cenas tīrelis and Teiči Nature Reserve . The climate, geography and environment of Finland favours bog and peat bog formation. Thus, peat

7872-603: 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

7968-513: The topic. In 2010, IPS presented a " Strategy for Responsible Peatland Management ", which can be applied worldwide for decision-making. Peat extraction is forbidden in Chile since April 2024. Often, restoration is done by blocking drainage channels in the peatland, and allowing natural vegetation to recover. Rehabilitation projects undertaken in North America and Europe usually focus on

8064-410: The tropical to boreal and Arctic zones from sea level to high alpine conditions. A more recent estimate from an improved global peatland map, PEATMAP, based on a meta-analysis of geospatial information at global, regional and national levels puts global coverage slightly higher than earlier peatland inventories at 4.23 million square kilometres (1.63 million square miles) approximately 2.84% of

8160-529: 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

8256-812: The water table and shading out many bog plants. Several families of plants including the carnivorous Sarracenia (trumpet pitcher), Dionaea (Venus flytrap), Utricularia (bladderworts) and non-carnivorous plants such as the sandhills lily , toothache grass and many species of orchid are now threatened and in some cases endangered from the combined forces of human drainage, negligence and absence of fire. The recent burning of peat bogs in Indonesia, with their large and deep growths containing more than 50 billion tonnes (55 billion short tons; 49 billion long tons) of carbon, has contributed to increases in world carbon dioxide levels. Peat deposits in Southeast Asia could be destroyed by 2040. It

8352-770: The water yellow or brown due to the leaching of tannins . Peat is widely used in balneotherapy (the use of bathing to treat disease). Many traditional spa treatments include peat as part of peloids . Such health treatments have an enduring tradition in European countries, including Poland, the Czech Republic, Germany and Austria. Some of these old spas date back to the 18th century and are still active today. The most common types of peat application in balneotherapy are peat muds , poultices and suspension baths . Authors Rydin and Jeglum in Biology of Habitats described

8448-436: The world by volume, in monetary terms, Latvian comes second in the world behind Canada . As an example, Latvia's income from exports was US$ 237 million. Latvia's peat deposits have been estimated to equal 1.7 billion tons. Latvia, as Finland due its climate has several peat bogs, which account for 9.9% of the country's territory. More than two thirds of the licensed areas for peat extraction are state-owned; 55% belong to

8544-479: The world land area. In Europe, peatlands extend to about 515,000 km (199,000 sq mi). About 60% of the world's wetlands are made of peat. Peat deposits are found in many places around the world, including northern Europe and North America. The North American peat deposits are principally found in Canada and the Northern United States. Some of the world's largest peatlands include

8640-447: 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

8736-466: The worldwide 500,000 km of degraded peatland may exceed 2.0 Gtons (including emissions from peat fires), which is almost 6% of all global carbon emissions. Peat can be a major fire hazard and is not extinguished by light rain. Peat fires may burn for great lengths of time, or smoulder underground and reignite after winter if an oxygen source is present. Peat has a high carbon content and can burn under low moisture conditions. Once ignited by

8832-497: 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

8928-468: 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

9024-474: 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

9120-570: 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

9216-786: 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
