Blue Lake (New South Wales)
The Blue Lake is one of only four cirque lakes found in mainland Australia. The other three, Cootapatamba, Lake Albina, Albina, and Club, are shallower and are held entirely by terminal moraines. Blue Lake's valley contains the best-developed glacier, glacial features in the Kosciuszko National Park Australian Alps, alpine area of New South Wales. It was recognised as a wetland of international importance on 17 March 1996 when a area, comprising the lake and its surrounds, including nearby Hedley Tarn, was designated Ramsar Site 800 under the Ramsar Convention on wetlands. The lake lies within the Australian Alps National Parks and Reserves. Description Blue Lake is in area and deep. Its surface is entirely open water, with boulders reaching the shore in the east and north east, and the other shores being pebbly. It lies about west of Jindabyne, New South Wales, Jindabyne and north of Charlotte Pass, New South Wales, Charlotte Pass at an altitude of Australian Height Datu ...

Snowy Mountains
The Snowy Mountains, known informally as "The Snowies", is an IBRA subregion in southern New South Wales, Australia, and is the tallest mountain range in mainland Australia, being part of the continent's Great Dividing Range cordillera system. It makes up the northeastern half of the Australian Alps (the other half being the Victorian Alps) and contains Australia's five tallest peaks, all of which are above , including the tallest Mount Kosciuszko, which reaches to a height of above sea level. The offshore Tasmanian highlands makes up the only other major alpine region present in the whole of Australia. The Snowy Mountains experiences large natural snowfalls every winter, normally during June, July, August and early September, with the snow cover melting by late spring. It is considered to be one of the centers of the Australian ski industry during the winter months, with all four snow resorts in New South Wales being located in the region. The range is host to the mou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Dividing Range
The Great Dividing Range, also known as the East Australian Cordillera or the Eastern Highlands, is a cordillera system in eastern Australia consisting of an expansive collection of mountain ranges, plateaus and rolling hills, that runs roughly parallel to the east coast of Australia and forms the fifth-longest land-based mountain chain in the world, and the longest entirely within a single country. It is mainland Australia's most substantial topographic feature and serves as the definitive watershed for the river systems in eastern Australia, hence the name. The Great Dividing Range stretches more than from Dauan Island in the Torres Strait off the northern tip of Cape York Peninsula, running the entire length of the eastern coastline through Queensland and New South Wales, then turning west across Victoria before finally fading into the Wimmera plains as rolling hills west of the Grampians region. The width of the Range varies from about to over .Shaw, John H., ''Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broad-toothed Mouse
The broad-toothed rat (''Mastacomys fuscus'') is a species of rodent in the family Muridae. Distribution and habitat It is found only in South-eastern Australia. In Victoria live specimens have been caught in the Snowfields, Great Dividing Range (to Cooma in New South Wales), Gippsland Highlands, Otway Ranges and Wilsons Promontory. Specimens located in scats have been found in the Otway plains and East Gippsland. The species is also recorded in buttongrass sedgeland up to 1000 metres in western Tasmania.Menkhorst and Knight, 2001 p. 198 Habitat preferences are areas of herbfields, grasslands and forests with minimal shrubs but a dense covering of sedge, grass, herbs and moss, where precipitation does not fall below 1400 mm per year in alpine areas and others 1000 mm at lower altitude Altitude or height (also sometimes known as depth) is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object.

Mountain Pygmy Possum
The mountain pygmy possum (''Burramys parvus''); also simply known as the burramys, is a small, mouse-sized (weighs ) nocturnal marsupial of Australia found in dense alpine rock screes and boulder fields, mainly southern Victoria and around Mount Kosciuszko in Kosciuszko National Park in New South Wales at elevations from . At almost , its prehensile tail is longer than its combined head and body length. Its diet consists of insects (such as the bogong moth), fleshy fruits, nuts, nectar and seeds. Its body is covered in a thick coat of fine grey fur except for its stomach, which is cream coloured; its tail is hairless. On the underside of the female's body is a pouch containing four teats. This possum is the only extant species in the genus ''Burramys''. It is also the only Australian mammal restricted to alpine habitat. Discovery The mountain pygmy possum was first discovered in the fossil record in 1895 when a portion of the jaw and skull bones were found in the Wombeyan Ca ...

Oschatzia Cuneifolia
''Oschatzia'' is a genus of flowering plants belonging to the family Apiaceae. It is also in the subfamily of ''Azorelloideae''. Its native range is south-eastern Australia, it is found in the states of New South Wales, Tasmania and Victoria. The genus name of ''Oschatzia'' is in honour of Adolph Oschatz (1812–1857), and German doctor and botanist.He was also an inventor of microtomy. It was first described and published in Ann. Bot. Syst. Vol.1 on page 340 in 1848. Known species According to Kew: *''Oschatzia cuneifolia ''Oschatzia'' is a genus of flowering plants belonging to the family Apiaceae.

Alpine Tundra
Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated alpine climate, harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges with tundra#Arctic tundra, polar tundra. The high elevation causes an adverse climate, which is too cold and windy to support tree growth. Alpine tundra ecotone, transitions to sub-alpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone are known as ''Krummholz''. With increasing elevation it ends at the snow line where snow and ice persist through summer. Alpine tundra occurs in mountains worldwide. The flora of the alpine tundra is characterized by dwarf shrubs close to the ground. The cold climate of the alpine tundra is caused by adiabatic cooling of air, and is similar to polar climate.

Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...

Heath (habitat)
A heath () is a shrubland habitat found mainly on free-draining infertile, acidic soils and characterised by open, low-growing woody vegetation. Moorland is generally related to high-ground heaths with—especially in Great Britain—a cooler and damper climate. Heaths are widespread worldwide but are fast disappearing and considered a rare habitat in Europe. They form extensive and highly diverse communities across Australia in humid and sub-humid areas where fire regimes with recurring burning are required for the maintenance of the heathlands.Specht, R.L. 'Heathlands' in 'Australian Vegetation' R.H. Groves ed. Cambridge University Press 1988 Even more diverse though less widespread heath communities occur in Southern Africa. Extensive heath communities can also be found in the Texas chaparral, New Caledonia, central Chile, and along the shores of the Mediterranean Sea. In addition to these extensive heath areas, the vegetation type is also found in scattered locations ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbfield
Herbfields are plant communities dominated by herbaceous plants, especially forbs and grasses. They are found where climatic conditions do not allow large woody plants to grow, such as in subantarctic and alpine tundra environments. Herbfield is defined in New South Wales (Australia) government legislation as native vegetation that predominantly does not contain an over-storey or a mid-storey and where ground cover is dominated by non-grass species. The New Zealand Department of Conservation The Department of Conservation (DOC; Māori: ''Te Papa Atawhai'') is the public service department of New Zealand charged with the conservation of New Zealand's natural and historical heritage. An advisory body, the New Zealand Conservation Au ... has described herbfield vegetation as that in which the cover of herbs in the canopy is 20–100%, and in which herb cover is greater than that of any other growth form, or of bare ground.Lux et al.

Snowmelt
In hydrology, snowmelt is surface runoff produced from melting snow. It can also be used to describe the period or season during which such runoff is produced. Water produced by snowmelt is an important part of the annual water cycle in many parts of the world, in some cases contributing high fractions of the annual runoff in a watershed. Predicting snowmelt runoff from a drainage basin may be a part of designing water control projects. Rapid snowmelt can cause flooding. If the snowmelt is then frozen, very dangerous conditions and accidents can occur, introducing the need for salt to melt the ice. Energy fluxes related to snowmelt There are several energy fluxes involved in the melting of snow. These fluxes can act in opposing directions, that is either delivering heat to or removing heat from the snowpack. Ground heat flux is the energy delivered to the snowpack from the soil below by conduction. Radiation inputs to the snowpack include net shortwave (solar radiation including ...
