Kimberley Tropical Savanna
The Kimberley tropical savanna is a tropical and subtropical grasslands, savannas, and shrublands ecoregion in northwestern Australia, covering portions of Western Australia and the Northern Territory south of the Timor Sea. Geography The ecoregion lies in Northwestern coastal Australia, including the Kimberley region of Western Australia and extending into the Northern Territory. It is bounded on the north by the Timor Sea. The Arnhem Land tropical savanna ecoregion lies to the northeast, the Carpentaria tropical savanna lies to the east, and the Victoria Plains tropical savanna ecoregion lies to the southeast and south. The Great Sandy-Tanami desert ecoregion lies to the southeast. Much of the ecoregion has rugged terrain of Proterozoic sandstone. The Northern Kimberley coast is generally steep with many offshore islets. Rivers in the ecoregion include the Fitzroy, May, Drysdale, Durack, Ord, Victoria, Katherine, Flora and Daly. Rivers and streams often follow sandston ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keep River National Park
Keep River National Park is in the Northern Territory of Australia, 418 km southwest of Darwin and 468 km west of Katherine. The nearest town is Kununurra in Western Australia. Environment The park has a number of striking sandstone formations and there is an Indigenous Australian art site at the end of the walk along the floor of the Keep River Gorge. The park falls within the tribal area of the Mirriwung and Gadjerong people. Most of the land in the park also lies within the Keep River Important Bird Area, identified as such because of its importance for the conservation of the endangered Gouldian finch.BirdLife International. (2011). Important Bird Areas factsheet: Keep River. Downloaded from http://www.birdlife.org on 2011-07-15. Access Like most of the Top End parks, access can be restricted due to flooding in the wet season. The most comfortable period for visiting is between May and August when the temperature ranges from a maximum of 35 °C to a minimum ...

Durack River
Durack River is a river in the Kimberley region of Western Australia. The river rises below the Durack Range then flows north, discharging into the west arm of Cambridge Gulf. There are 14 tributaries of the Durack, including Chapman River, Wood River, Ellenbrae Creek, Royston Creek, Koolawerii Creek and Wilson Creek. The river was named in 1882 by the surveyor John Pentecost after explorer and Kimberley pioneer Michael Durack, who was the first European to cross the river. The traditional owners of the area that the river flows through are the Kitja, Ola and Wilawila The Wilawila are an indigenous Australian tribe of the Kimberley region of Western Australia. Name Norman Tindale gave "wilawila" as the proper tribal ethnonym, but noted that, according to reports by the missionary Theodore Hernández, the sa ... peoples.

IBRA Region
The Interim Biogeographic Regionalisation for Australia (IBRA) is a biogeography, biogeographic regionalisation of Australia developed by the Australian government's Department of Sustainability, Environment, Water, Population and Communities (Australia), 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, 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 ecoregion, 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 ...

Duricrust
Duricrust is a hard layer on or near the surface of soil. Duricrusts can range in thickness from a few millimeters or centimeters to several meters. It is a general term (not to be confused with duripan) for a zone of chemical precipitation and hardening formed at or near the surface of sedimentary bodies through pedogenic and (or) non-pedogenic processes. It is typically formed by the accumulation of soluble minerals deposited by mineral-bearing waters that move upward, downward, or laterally by capillary action, commonly assisted in arid settings by evaporation.Dixon, J.C. and McLaren, S.J., 2009.

Bauxite
Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)4) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2). Bauxite appears dull in luster and is reddish-brown, white, or tan. In 1821, the French geologist Pierre Berthier discovered bauxite near the village of Les Baux in Provence, southern France. Formation Numerous classification schemes have been proposed for bauxite but, , there was no consensus. Vadász (1951) distinguished lateritic bauxites (silicate bauxites) from karst bauxite ores (carbonate bauxites): * The carbonate bauxites occur predominantly in Europe, Guyana, Suriname, and Jamaica above carbonate rocks (limestone and do ...

Daly River (Northern Territory)
The Daly River is a river in the Northern Territory of Australia. Settlement on the river is centred on the Aboriginal community of Nauiyu, originally the site of a Catholic mission, as well as the town of Daly River itself, at the river crossing a few kilometres to the south. The Daly River is part of the Daly Catchment that flows from northern Northern Territory to central Northern Territory. The Daly River flows from the confluence of the Flora River and Katherine River to its mouth on the Timor Sea. History The traditional owners of the area are the Mulluk-Mulluk people. Boyle Travers Finniss named the river after Sir Dominick Daly, the Governor of South Australia, as the Northern Territory was at that time part of South Australia. The region then lay untouched by Europeans until 1882 when copper was discovered. Floods Like other rivers of the top end, the Daly is prone to seasonal flooding. Major flood events devastated the town of Daly River in 1899 and 1957, causi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora River
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
