The Tirari–Sturt stony desert is a deserts and xeric shrublands ecoregion in central Australia.
The Tirari–Sturt stony desert ecoregion contains the gibber plains (desert pavement) and red sands of the large Sturt Stony Desert, the Tirari Desert to its southwest and the Flinders and Gawler Ranges to the south. The Tirari has more sand dunes than the Sturt Stony Desert and has also been the site of some important fossil findings. Towns of the ecoregion include the opal mining centre of Coober Pedy, famous for its underground dwellings. The climate is very hot with summer temperatures reaching 50 °C.
The region consists of the Stony Plains, Gawler, Flinders Lofty Block and the Broken Hill Complex bioregions of the Interim Biogeographic Regionalisation for Australia (IBRA).
As well as stony plain and sands there are areas of chenopod, mallee and mulga wooded scrubland. The region is home to a variety of wildlife that has adapted to the hot dry conditions including the wedge-tailed eagles, yellow-footed rock wallaby and western grey kangaroos of the Flinders Ranges.
The desert proper is uninhabitable and the environment there remains undamaged, while the greener fringe are used for sheep grazing.
10.34% of the ecoregion is in protected areas. Protected areas include:
The Great Victoria Desert is a sparsely populated desert ecoregion and interim Australian bioregion in Western Australia and South Australia.
The Carnarvon xeric shrublands is a deserts and xeric shrublands ecoregion of Western Australia. The ecoregion is coterminous with the Carnarvon Interim Biogeographic Regionalisation for Australia (IBRA) bioregion.
The Murchison is an interim Australian bioregion located within the Mid West of Western Australia. The bioregion is loosely related to the catchment area of the Murchison River and has an area of 281,205 square kilometres (108,574 sq mi). Traditionally the region is known as The Murchison.
The Barkly Tableland is a rolling plain of grassland in Australia. It runs from the eastern part of the Northern Territory into western Queensland. It is one of the five regions in the Northern Territory and covers 283,648 square kilometres (109,517 sq mi), 21% of the Northern Territory. The Barkly Tableland runs parallel to the southern shore of the Gulf of Carpentaria, from about Mount Isa, Queensland to near Daly Waters.
The deserts of Australia or the Australian deserts cover about 2,700,000 km2 (1,000,000 sq mi), or 18% of the Australian mainland, but about 35% of the Australian continent receives so little rain, it is practically desert. Collectively known as the Great Australian desert, they are primarily distributed throughout the Western Plateau and interior lowlands of the country, covering areas from South West Queensland, Far West region of New South Wales, Sunraysia in Victoria and Spencer Gulf in South Australia to the Barkly Tableland in Northern Territory and the Kimberley region in Western Australia.
Esperance Plains, also known as Eyre Botanical District, is a biogeographic region in southern Western Australia on the south coast between the Avon Wheatbelt and Hampton bioregions, and bordered to the north by the Mallee region. It is a plain punctuated by granite and quartz outcrops and ranges, with a semi-arid Mediterranean climate and vegetation consisting mostly of mallee-heath and proteaceous scrub. About half of the region has been cleared for intensive agriculture. Recognised as a bioregion under the Interim Biogeographic Regionalisation for Australia (IBRA), it was first defined by John Stanley Beard in 1980.
Mallee, also known as Roe Botanical District, is a biogeographic region in southern Western Australia. Located between the Esperance Plains, Avon Wheatbelt and Coolgardie bioregions, it has a low, gently undulating topography, a semi-arid mediterranean climate, and extensive Eucalyptus mallee vegetation. It has an area of 73,975.59 square kilometres (28,562.13 sq mi). About half of the region has been cleared for intensive agriculture. Recognised as a region under the Interim Biogeographic Regionalisation for Australia (IBRA), it was first defined by John Stanley Beard in 1980.
Warren, also known as Karri Forest Region and the Jarrah-Karri forest and shrublands ecoregion, is a biogeographic region in southern Western Australia. Located in the southwest corner of Western Australia between Cape Naturaliste and Albany, it is bordered to the north and east by the Jarrah Forest region. Its defining characteristic is an extensive tall forest of Eucalyptus diversicolor (karri). This occurs on dissected, hilly ground, with a moderately wet climate. Karri is a valuable timber and much of the karri forest has been logged over, but less than a third has been cleared for agriculture. Recognised as a region under the Interim Biogeographic Regionalisation for Australia (IBRA), and as a terrestrial ecoregion by the World Wide Fund for Nature, it was first defined by Ludwig Diels in 1906.
Coolgardie is an Australian bioregion consisting of an area of low hills and plains of infertile sandy soil in Western Australia. It has an area of 129,122.09 square kilometres (49,854.32 sq mi). It includes much of the Great Western Woodlands.
Gascoyne is an interim Australian bioregion located in Western Australia. It has an area of 180,752.57 square kilometres (69,788.96 sq mi). Together with Murchison bioregion to the south, it constitutes the Western Australian Mulga shrublands ecoregion, as assessed by the World Wildlife Fund.
Hampton is an interim Australian bioregion located in southeastern coastal Western Australia, with a small portion (4%) extending into adjacent South Australia. It has an area of 1,088,198 hectares. The Hampton bioregion is part of the Coolgardie woodlands ecoregion.
The Ord Victoria Plain, an interim Australian bioregion, is located in the Northern Territory and Western Australia, comprising 12,540,703 hectares.
The Eyre Yorke Block, also known as the Eyre and Yorke mallee, is an interim Australian (IBRA) bioregion and a World Wildlife Fund ecoregion covering part of the Eyre Peninsula and all of Yorke Peninsula as well as land to its immediate east in South Australia.
The Mount Lofty woodlands, or the Peppermint Box Grassy Woodland of South Australia is an ecoregion in South Australia, which includes woodlands, shrublands, and grasslands in the Mount Lofty Ranges, Fleurieu Peninsula, and Kangaroo Island.
The Central Ranges xeric scrub is a deserts and xeric shrublands ecoregion of Australia.
The Great Sandy-Tanami desert is a ecoregion of Western Australia extending into the Northern Territory. It is designated as a World Wildlife Fund region.
The Western Australian Mulga shrublands is a deserts and xeric shrublands ecoregion of inland Western Australia. It is one of Australia's two mulga ecoregions, characterized by dry woodlands of mulga trees interspersed with areas of grassland and scrub.
Flinders Lofty Block is an interim Australian bioregion located in South Australia. It has an area of 6,615,765 hectares, which includes the Mount Lofty Ranges and Flinders Ranges.
Gawler is an interim Australian bioregion located in South Australia. It has an area of 12,002,883 hectares. Gawler bioregion is part of the Tirari–Sturt stony desert ecoregion.
