Tirari–Sturt Stony Desert
The Tirari–Sturt stony desert is a deserts and xeric shrublands ecoregion in central Australia. Location and description 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).

These Aboriginal Australians, Aboriginal peoples maintained and used rock holes in the granite rock formations as a water source. The ranges were named by Edward John Eyre after the Governor of South Australia, George Gawler in 1839. This was on one of Eyre's Eyre's 1839 expeditions, earlier expeditions before his famous crossing of the Nullarbor Plain further west. It was on this expedition that Edward John Eyre made the fir ...

Gibber Plain
A desert pavement, also called reg (in the western Sahara), serir (eastern Sahara), gibber (in Australia), or saï (central Asia) is a desert surface covered with closely packed, interlocking angular or rounded rock fragments of pebble and cobble size. They typically top alluvial fans. Desert varnish collects on the exposed surface rocks over time. Geologists debate the mechanics of pavement formation and their age. Formation Several theories have been proposed for the formation of desert pavements. A common theory suggests that they form through the gradual removal of sand, dust and other fine-grained material by the wind and intermittent rain, leaving the larger fragments behind. The larger fragments are shaken into place through the forces of rain, running water, wind, gravity, creep, thermal expansion and contraction, wetting and drying, frost heaving, animal traffic, and the Earth's constant microseismic vibrations. The removal of small particles by wind does not continue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Interim Biogeographic Regionalisation For Australia
The Interim Biogeographic Regionalisation for Australia (IBRA) is a biogeographic regionalisation of Australia developed by the Australian government's Department of Sustainability, Environment, Water, Population, and Communities. It was developed for use as a planning tool, for example for the establishment of a national reserve system. The first version of IBRA was developed in 1993–94 and published in 1995. Within the broadest scale, Australia is a major part of the Australasia biogeographic realm, as developed by the World Wide Fund for Nature. Based on this system, the world is also split into 14 terrestrial habitats, of which eight are shared by Australia. The Australian land mass is divided into 89 bioregions and 419 subregions. Each region is a land area made up of a group of interacting ecosystems that are repeated in similar form across the landscape. IBRA is updated periodically based on new data, mapping improvements, and review of the existing scheme. The most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bioregion
A bioregion is an ecologically and geographically defined area that is smaller than a biogeographic realm, but larger than an ecoregion or an ecosystem, in the World Wide Fund for Nature classification scheme. There is also an attempt to use the term in a rank-less generalist sense, similar to the terms "biogeographic area" or "biogeographic unit". It may be conceptually similar to an ecoprovince. It is also differently used in the environmentalist context, being coined by Berg and Dasmann (1977). WWF bioregions The World Wide Fund for Nature (WWF) scheme divides some of the biogeographic realms into bioregions, defined as "geographic clusters of ecoregions that may span several habitat types, but have strong biogeographic affinities, particularly at taxonomic levels higher than the species level (genus, family)." The WWF bioregions are as follows: * Afrotropical realm **Western Africa and Sahel **Central Africa **Eastern and Southern Africa ** Horn of Africa **Madagascar–I ...

Coober Pedy
Coober Pedy () is a town in northern South Australia, north of Adelaide on the Stuart Highway. The town is sometimes referred to as the "opal capital of the world" because of the quantity of precious opals that are mined there. Coober Pedy is renowned for its below-ground dwellings, called " dugouts", which are built in this fashion due to the scorching daytime heat. The name "Coober Pedy" is thought to derive from the Aboriginal term ''kupa-piti'', which means "whitefellas' hole", but in 1975 the local Aboriginal people of the town adopted the name Umoona, which means "long life" and is also their name for the mulga tree. In the 2016 Australian census, there were 1,762 people in Coober Pedy. History Aboriginal peoples have a long-standing connection with the area. Coober Pedy is considered by the senior Western Desert people to be the traditional lands of the Arabana people country, but Kokatha and Yankunytjatjara people are also closely attached to some ceremonial ...
