Ngururrpa Indigenous Protected Area
The Ngururrpa Indigenous Protected Area (Ngururrpa IPA), covering an area of in the far eastern area of the Pilbara region, in the Great Sandy Desert of Western Australia, was declared in October 2020. It includes all of the land included in the Ngururrpa native title area, as determined in 2007. Background Peoples of the Walmajarri, Wangkatjunga, Ngarti and Kukatja language groups have called their country Ngururrpa, meaning "our country in the middle", and they are recognised as the traditional owners of the area; the IPA comprises the whole of the Ngururrpa native title determination made in 2007. The people lived a traditional lifestyle in the area until around the 1950s. Some elders remember seeing white people for the first time. They were left alone more than some of the surrounding groups, owing to the type of land offering poor grazing for European livestock, and there are no mines in the area. This also means that today there are no mining or pastoral jobs, and few o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pilbara
The Pilbara () is a large, dry, thinly populated region in the north of Western Australia. It is known for its Aboriginal peoples; its ancient landscapes; the red earth; and its vast mineral deposits, in particular iron ore. It is also a global biodiversity hotspot for subterranean fauna. Definitions of the Pilbara region At least two important but differing definitions of "the Pilbara" region exist. Administratively it is one of the nine regions of Western Australia defined by the ''Regional Development Commissions Act 1993''; the term also refers to the Pilbara shrublands bioregion (which differs in extent) under the Interim Biogeographic Regionalisation for Australia (IBRA). General The Pilbara region, as defined by the Regional Development Commissions Act 1993 and administered for economic development purposes by the Pilbara Development Commission, has an estimated population of 61,688 , and covers an area of . It contains some of Earth's oldest rock formations, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandplain
A sandplain is an area where the soil is sand deposited from elsewhere by processes such as wind or ocean, rather than direct weathering of bedrock. Sandplains are quite flat. There may be dune systems, and given time and the right conditions these may form eolianite ridges, but other than that there is little to give a sandplain any topographical character. Inland sandplains are often extremely infertile, because the sand is often low in nutrients when deposited, plus the good drainage means any nutrients are rapidly leached away. Coastal sandplains in intertidal zones like those seen in the Wadden Sea in western Europe for example, are wet with nutrients added continuously, so they can often support a very rich and important fauna of birds, worms, mussels, etc.. In North America, sandplains are often vegetated by pine barrens. In Western Australia, kwongan is the dominant vegetation.

Ipomoea Costata
''Ipomoea costata'', commonly known as rock morning glory, is an Australian flora, Australian native plant. It is found in northern Australia, from Western Australia, through the Northern Territory, to Queensland. Its tubers provide a form of bush tucker to some Aboriginal Australians, Aboriginal peoples, known as bush potato, or (to the Ngururrpa groups in WA), karnti. Description It is a prostrate or climbing perennial growing up to 3 m high, with purple-blue-pink flowers from February to November. Juvenile form is a vine, maturing into a woody-stemmed shrub with vine-like stems. Leaves are broad and leathery, 4-9 cm long. Tubers are rounded, 12-20 cm long by 5-18 cm wide, with a single plant potentially having up to twenty tubers. Habitat It occurs on sandy or rocky soils, often over limestone, and on Triodia (plant), spinifex sand plains in northern Australia. Uses It is the source of bush potato, a bush tucker food for Aboriginal Australians, Aboriginal people. Bush p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bush Tucker
Bush tucker, also called bush food, is any food native to Australia and used as sustenance by Indigenous Australians, the Aboriginal and Torres Strait Islander peoples, but it can also describe any native flora or fauna used for culinary or medicinal purposes, regardless of the continent or culture. Animal native foods include kangaroo, emu, witchetty grubs and crocodile, and plant foods include fruits such as quandong, kutjera, spices such as lemon myrtle and vegetables such as warrigal greens and various native yams. Traditional Indigenous Australians' use of bushfoods has been severely affected by the settlement of Australia in 1788 and subsequent settlement by non-Indigenous peoples. The introduction of non-native foods, together with the loss of traditional lands, resulting in reduced access to native foods by Aboriginal people, and destruction of native habitat for agriculture, has accentuated the reduction in use. Since the 1970s, there has been recognition of the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lateritic
Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate wet and dry periods. Tropical weathering (''laterization'') is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the resulting soils. The majority of the land area containing laterites is between the tropics of Cancer and Capricorn. Laterite has commonly been referred to as a soil type as well as being a rock type. This and further variation in the modes of conceptualizing about laterite (e.g. also as a complete weathering profile or theory about weathering) has led to calls for the term to be abandoned al ...

Acacia Hilliana
''Acacia hilliana'', commonly known as Hill's tabletop wattle but also known as sandhill wattle and Hilltop wattle, is a shrub belonging to the genus ''Acacia'' and the subgenus ''Juliflorae''. It is native to northern Australia. The Indigenous Australian peoples the Banyjima know it as ''Bundaljingu'' and the Nyangumarta know it as ''Puntanungu''. Description The low spreading, viscid shrub typically grows to a height of . The obscurely ribbed branches normally spread horizontally giving the shrub a flat-topped appearance. The green to grey-green phyllodes are solitary or sometimes in clusters of two or three at the nodes. Each phyllode is in length and has a diameter of about and are straight or curve shallowly upward. It blooms from March to October producing golden yellow flowers. The simple inflorescences have an erect flower spike that is in length. Following flowering flat, thick and linear dark brown seed pods with a length of and a width of . The erect and woody p ...

Triodia (plant)
''Triodia'' is a large genus of hummock-forming bunchgrass endemic to Australia. They are known by the common name spinifex, although they are not a part of the coastal genus '' Spinifex''. Many of the soft-leaved members of this species were formerly included in the genus ''Plectrachne''. It is known as ''tjanpi'' in central Australia, and is used for basket weaving by the women of various Aboriginal Australian peoples. A multiaccess key (SpiKey) is available as a free application for identifying the ''Triodia'' of the Pilbara (28 species and one hybrid). Description ''Triodia'' is a perennial Australian tussock grass that grows in arid regions. Its leaves (30–40 centimetres long) are subulate ( awl-shaped, with a tapering point). The leaf tips, that are high in silica, can break off in the skin, leading to infections. Uses Spinifex has traditionally had many uses for Aboriginal Australians. The seeds were collected and ground to make seedcakes. Spinifex resin was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acacia
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of ''Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''—the type species. This meant that the Australasian lineage (by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire-stick Farming
Fire-stick farming, also known as cultural burning and cool burning, is the practice of Aboriginal Australians regularly using fire to burn vegetation, which has been practised for thousands of years. There are a number of purposes for doing this special type of controlled burning, including to facilitate hunting, to change the composition of plant and animal species in an area, weed control, hazard reduction, and increase of biodiversity. While it had been discontinued in many parts of Australia, it has been reintroduced in the 21st century by the teachings of custodians from areas where the practice is extant in continuous unbroken tradition such as the Noongar peoples' cold fire. Terminology The term "fire-stick farming" was coined by Australian archaeologist Rhys Jones in 1969. It has more recently been called cultural burning and cool burning. History Aboriginal burning has been proposed as the cause of a variety of environmental changes, including the extinction of th ...

Swamp
A swamp is a forested wetland.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations.Hughes, F.M.R. (ed.). 2003. The Flooded Forest: Guidance for policy makers and river managers in Europe on the restoration of floodplain forests. FLOBAR2, Department of Geography, University of Cambridge, Cambridge, UK. 96 p. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammock (ecology), hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates ...

Claypan
Claypan is a dense, compact, slowly permeable layer in the subsoil. It has a much higher clay content than the overlying material, from which it is separated by a sharply defined boundary. The dense structure restricts root growth and water infiltration. Therefore, a perched water table might form on top of the claypan. In the Canadian classification system, claypan is defined as a clay-enriched illuvial B (Bt) horizon. Location Claypan is present in a wide area of the central United States (about 4 million ha) across multiple states such as Kansas, Oklahoma, and Illinois. It can also be found in Australia throughout the south-west Queensland. Formation Claypan is formed in different parent materials depending on geological locations, such as floodplains. The formation of the claypan relates to a lack of vegetation coverage, soil particle size distribution, and high rainfall. The lack of vegetation coverage makes soil become more susceptible to raindrop attacks. When the raindro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ephemeral Lake
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
