Pungalina-Seven Emu Sanctuary
Pungalina-Seven Emu Sanctuary is a 3060 km2 private protected area in the Northern Territory of Australia. It is managed by the Australian Wildlife Conservancy (AWC) which purchased Pungalina Station in 2009, with some assistance from the Wildlife Australia Fund. It adjoins the Gulf of Carpentaria near the border with Queensland, lying in the Gulf Coastal bioregion. The reserve is bordered by Calvert Hills and Wollogorang Stations to the south and east. The nearest town is Borroloola, 150 km to the west. History The reserve is made up of two separate pastoral properties, Pungalina and Seven Emu. Pungalina is a former cattle station while Seven Emu is owned by a Garawa man, Frank Shadforth, who has subleased of the property to AWC for wildlife conservation since 2009. Seven Emu has of coastline and links Pungalina to the coast. The arrangement is a historic partnership between a non-profit, private conservation organisation and an Indigenous landholder. Se ...

Borroloola, Northern Territory
Borroloola ( local Aboriginal languages: ''Burrulula'') is a town in the Northern Territory of Australia. It is located on the McArthur River, about 50 km upstream from the Gulf of Carpentaria. Location Borroloola lies on the traditional country of the Yanyuwa people, on the coastal plain between the Barkly Tablelands and the Gulf of Carpentaria. Rivers that run from the Tablelands escarpment to the Gulf regularly flood in the wet season, making travel on the unsealed section of Highway One along the coastal plain to Queensland impossible. The rivers of this region have carved spectacular gorges through sandstone deposits in their upper reaches. The rivers and coastal areas are host to barramundi, earning Borroloola a reputation among sports fisherman, and also to the deadly saltwater crocodile. The region has little rain from May to September and is characterised by lightly treed Savanna grasslands. History Garrwa (also known as Garawa) is a language of the Gulf regio ...

Port Essington
Port Essington is an inlet and historic site located on the Cobourg Peninsula in the Garig Gunak Barlu National Park in Australia's Northern Territory. It was the site of an early attempt at British settlement, but now exists only as a remote series of ruins. Settlement In August 1618 Lenaert Jacobszoon, the captain of the Dutch East India Company vessel ''Mauritius'', marked the point on the entrance to what was later called Port Essington, on the Dutch charts as Kape Schildpad (Cape Turtle). In the early 19th century, the British government became interested in establishing a settlement on Australia's northern coastline in order to facilitate trade with Asia. Port Essington was named on 23 April 1818 by Phillip Parker King in 'as a tribute of my respect for the memory of my lamented friend, Vice-Admiral Sir William Essington', who was in command of ''Triumph'' at the battle of Camperdown in October 1797. Sir J.G.Bremer took possession of the mainland on 20 September 182 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wetland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or seawater, saltwater. The main w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh wa ...

Woodland
A woodland () is, in the broad sense, land covered with trees, or in a narrow sense, synonymous with wood (or in the U.S., the ''plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American, and Australian English explained below). Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests. Extensive efforts by conservationist groups have been made to preserve woodlands from urbanization and agriculture. For example, the woodlands of Northwest Indiana have been preserved as part of the Indiana Dunes. Definitions United Kingdom ''Woodland'' is used in British woodland management to mean tre ...

Floodplain
A floodplain or flood plain or bottomlands is an area of land adjacent to a river which stretches from the banks of its channel to the base of the enclosing valley walls, and which experiences flooding during periods of high discharge.Goudie, A. S., 2004, ''Encyclopedia of Geomorphology'', vol. 1. Routledge, New York. The soils usually consist of clays, silts, sands, and gravels deposited during floods. Because the regular flooding of floodplains can deposit nutrients and water, floodplains frequently have high soil fertility; some important agricultural regions, such as the Mississippi river basin and the Nile, rely heavily on the flood plains. Agricultural regions as well as urban areas have developed near or on floodplains to take advantage of the rich soil and fresh water. However, the risk of flooding has led to increasing efforts to control flooding. Formation Most floodplains are formed by deposition on the inside of river meanders and by overbank flow. Whereve ...

Plateau
In geology and physical geography, a plateau (; ; ), also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills or escarpments. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental. A few plateaus may have a small flat top while others have wide ones. Formation Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, Plate tectonics movements and erosion by water and glaciers. Volcanic Volcanic plateaus are produced by volcanic activity. The Columbia Plateau in the north-western United States is an example. They may be formed by upwelling of volcanic magma or extrusion of lava. The un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalypt
Eucalypt is a descriptive name for woody plants with capsule fruiting bodies belonging to seven closely related genera (of the tribe Eucalypteae) found across Australasia: ''Eucalyptus'', '' Corymbia'', '' Angophora'', ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum''. Taxonomy For an example of changing historical perspectives, in 1991, largely genetic evidence indicated that some prominent ''Eucalyptus'' species were actually more closely related to ''Angophora'' than to other eucalypts; they were accordingly split off into the new genus ''Corymbia''. Although separate, all of these genera and their species are allied and it remains the standard to refer to the members of all seven genera ''Angophora'', ''Corymbia'', ''Eucalyptus'', ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum'' as "eucalypts" or as the eucalypt group. The extant genera ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum'' comprise six k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalyptus
''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including '' Corymbia'', they are commonly known as eucalypts. Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which survive fire. A few species are native to islands north of Australia and a smaller number are only found outside the continent. Eucalypts have been grow ...

Cyclone
In meteorology, a cyclone () is a large air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone). Cyclones are characterized by inward-spiraling winds that rotate about a zone of low pressure. The largest low-pressure systems are polar vortices and extratropical cyclones of the largest scale (the synoptic scale). Warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within the synoptic scale. Mesocyclones, tornadoes, and dust devils lie within smaller mesoscale. Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the tropical upper tropospheric trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, such as Mars, Jupiter, and Neptune. Cyclogenesis is the process of cyclone formation and ...

Tropical Monsoon Climate
An area of tropical monsoon climate (occasionally known as a sub-equatorial, tropical wet climate or a tropical monsoon and trade-wind littoral climate) is a tropical climate sub-type that corresponds to the Köppen climate classification category ''Am''. Tropical monsoon climates have monthly mean temperatures above in every month of the year and a dry season. The tropical monsoon climate is the intermediate climate between the wet Af (or tropical rainforest climate) and the drier Aw (or tropical savanna climate). A tropical monsoon climate's driest month has on average less than 60 mm, but more than 100-\left(\frac\right). This is in direct contrast to a tropical savanna climate, whose driest month has less than 60 mm of precipitation and also less than 100-\left(\frac\right) of average monthly precipitation. In essence, a tropical monsoon climate tends to either have more rainfall than a tropical savanna climate or have less pronounced dry seasons. A tropical monsoon c ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
