Lake Gregory (South Australia)
Lake Gregory is a salt lake located in the Far North region of South Australia. The lake lies to the west of Lake Blanche; to the east the Birdsville Track runs in between it and Lake Eyre. Hydrology Lake Gregory is fed by local rainfall and by overflows from Lake Blanche to its east. It was filled in 1974, 1984 and 1990. Natural history The lake is located within the boundaries of the 'Strzelecki Creek Wetland System', a DIWA wetland, and the Strzelecki Desert Lakes Important Bird Area. History It is named after the explorer Augustus Charles Gregory, who first passed by it in 1858. Originally Lake Eyre was named Lake Gregory by B. H. Babbage, but the names were modified by Governor Richard Graves MacDonnell, who preferred to name the former after the famous explorer who first investigated the region twenty years prior, Edward John Eyre. Economy The lands around the lake are used for pastoralism, with both sheep and cattle grazing the surrounding plains. Dulkaninna ...

Sentinel-2
Sentinel-2 is an Earth observation mission from the Copernicus Programme that acquires optical imagery at high spatial resolution (10 m to 60 m) over land and coastal waters. The mission's Sentinel-2A and Sentinel-2B satellites were joined in orbit in 2024 by a third, Sentinel-2C, and in the future by Sentinel-2D, eventually replacing the A and B satellites, respectively. The mission supports services and applications such as agricultural monitoring, emergencies management, land cover classification, and water quality. Sentinel-2 has been developed and is being operated by the European Space Agency. The satellites were manufactured by a consortium led by Airbus Defence and Space in Friedrichshafen, Germany. Overview The Sentinel-2 mission includes: * Multispectral image, Multi-spectral data with 13 bands in the Visible spectrum, visible, Infrared#Regions within the infrared, near infrared, and Infrared#Regions within the infrared, short wave infrared part of the Electromagnetic ...

Birdsville Track
The Birdsville Track is an outback road in Australia. The track runs between Birdsville in south-western Queensland and Marree, a small town in the north-eastern part of South Australia. It traverses three deserts along the route, the Strzelecki Desert, Sturt Stony Desert and Tirari Desert. Originally the track was of poor quality and suitable for high-clearance four-wheel drive vehicles only, but it is now a graded dirt road and a popular tourist route. It is also used by cattle trucks carrying livestock. The track passes through one of the driest parts of Australia, with an average rainfall of less than 100 mm annually. The area is extremely barren, dry and isolated. Travellers should carry water and supplies in case of emergencies. History The track was opened in the 1860s to walk cattle from northern Queensland and the Northern Territory to the nearest railhead in Port Augusta, which was later moved to Marree. The pioneering drover credited with establishing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Lakes Of Australia
Natural freshwater lakes in Australia are rare due to the general absence of Glacier, glacial and Plate tectonics, tectonic activity in Australia. Types Most lakes in Australia fall within one of five categories. Excluding lakes and lagoons created by List of reservoirs and dams in Australia, man-made dams for water storage and other purposes, one can identify the following: * coastal lakes and lagoons including perched lakes; * natural freshwater inland lakes, often ephemeral and some part of wetland or swamp areas; * the Main Range (Snowy Mountains), Main Range containing mainland Australia's five glacial lakes. In Tasmania, due to glaciation, there are a large number of natural freshwater lakes on the central plateau, many of which have been enlarged or modified by hydro-electric developments; * predominantly dry, salt lake (geography), salt lakes in the flat desert regions of the country lacking organised drainage; and * lakes created in volcanic remnants.

Dulkaninna
Dulkaninna Station is a pastoral lease that once operated as a sheep station but now operates as a cattle station in outback South Australia. It is along the Birdsville Track approximately north of Marree at the southern end of the Tirari Desert. The property is composed of a variety of land systems including gibber plains, black soil flood plains, sand-hill country, table land country and creek systems. Lake Gregory is in the north-east corner of the property. It shares a boundary with Clayton Station to the south-west, Murnpeowie to the south-east and Etadunna Station to the north. The property occupies an area of and runs beef cattle; it is a certified organic producer. The Bell family own the property and have down so for over 110 years. The property runs a herd of Poll Hereford crossed with Black Angus and also breeds stock and quarter horses.

Pastoralism
Pastoralism is a form of animal husbandry where domesticated animals (known as "livestock") are released onto large vegetated outdoor lands (pastures) for grazing, historically by nomadic people who moved around with their herds. The animal species involved include cattle, camels, goats, yaks, llamas, reindeer, horses, and sheep. Pastoralism occurs in many variations throughout the world, generally where environmentally effected characteristics such as aridity, poor soils, cold or hot temperatures, and lack of water make crop-growing difficult or impossible. Operating in more extreme environments with more marginal lands means that pastoral communities are very vulnerable to the effects of global warming. Pastoralism remains a way of life in many geographic areas, including Africa, the Tibetan plateau, the Eurasian steppes, the Andes, Patagonia, the Pampas, Australia and many other places. , between 200 million and 500 million people globally practiced pa ...

Strzelecki Desert Lakes Important Bird Area
The Strzelecki Desert Lakes Important Bird Area is an Important Bird Area (IBA) in the Australian state of South Australia which consists of a series of ephemeral waterbodies in the arid Strzelecki Desert in the state's Far North region. It is considered to be important for waterbirds when its constituent lakes hold water in the aftermath of floods. Description The Important Bird Area consists of a chain of lakes, of varying levels of salinity, on the lower Cooper and Strzelecki Creeks in north-eastern South Australia. The site is defined by the maximum extent of the Cooper Creek floodplain from Lakes Hope and Appadare to Lakes Killalpaninna, Kooperamanna and Killamperpunna, as well as Lakes Gregory, Blanche and Callabonna. Although the creek systems flood irregularly, water may persist in the lakes for several years. Criteria for nomination as an IBA The site has been identified by BirdLife International as an IBA because it has supported significant numbers of freckled ...

Lake Eyre
Lake Eyre ( ), officially known as Kati Thanda–Lake Eyre, is an endorheic lake in the east-central part of the Far North (South Australia), Far North region of South Australia, some 700 km (435 mi) north of Adelaide. It is the largest ephemeral endorheic lake on the Australian continent, covering over 9,000 km2 (3,500 sq mi). The shallow lake is the depocentre of the vast endorheic Lake Eyre basin, and contains the lowest natural point in Australia, at approximately 15 m (49 ft) below sea level. The lake is most often empty, filling partially mostly when flooding occurs upstream in Channel Country. On the rare occasions that it fills completely (only three times between 1860 and 2025), it is the largest lake in Australia, covering an area of up to . When the lake is full, it has the same salinity as seawater, but becomes hypersaline lake, hypersaline as the lake dries up and the water evaporates. To the north of the lake is the Simpson Deser ...
