Maisie Carr
Maisie Carr (''née'' Fawcett; 1912–1988) was an innovative Australian ecologist and botanist who contributed much to the understanding of the uniqueness of Australian plants and their environmental systems. Foundation years Maisie Carr was born Stella Grace Maisie Fawcett in Footscray, Melbourne. Neither of her parents had a science background but her love of plants was likely fostered by visits to nearby salt-marshes, her grandmother's garden and in nature study classes. Carr attended Footscray's Hyde Street State School where she was first in her class and Dux in 1924 and then attended Melbourne High School. Her diligence was evident at an early age; in 1920 she won £2 in a competition for finding the largest number (87) of Australian postal towns within the letters of ''AUSTRALBA TOOTH PASTE'' (the sponsor of the competition). After graduation she returned to her old primary school as a junior teacher while at night studying zoology and geology at Austral Coaching Col ...

Footscray, Victoria
Footscray is an inner-city suburb in Melbourne, Victoria, Australia, west of Melbourne's Central Business District, located within the City of Maribyrnong local government area. Footscray recorded a population of 17,131 at the . Footscray is characterised by a very diverse, multicultural central shopping area, which reflects the successive waves of immigration experienced by Melbourne, and by Footscray in particular. Once a centre for Greek, Italian and former Yugoslavian migrants, it later became a hub for Vietnamese and East African immigrants in Melbourne. It has recently begun to undergo rapid development and gentrification, and '' Time Out'' magazine placed Footscray at 13th in its '50 Coolest Neighbourhoods in the World' for 2019, reflecting its evolving reputation, citing in particular its diverse array of international cuisine, bars and nightlife, as well as its arts scene. Footscray is named after Foots Cray, on the River Cray in London, England. History Footscra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Australia
South Australia (commonly abbreviated as SA) is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of , it is the fourth-largest of Australia's states and territories by area, and second smallest state by population. It has a total of 1.8 million people. Its population is the second most highly centralised in Australia, after Western Australia, with more than 77 percent of South Australians living in the capital Adelaide, or its environs. Other population centres in the state are relatively small; Mount Gambier, the second-largest centre, has a population of 33,233. South Australia shares borders with all of the other mainland states, as well as the Northern Territory; it is bordered to the west by Western Australia, to the north by the Northern Territory, to the north-east by Queensland, to the east by New South Wales, to the south-east by Victoria, and to the south by the Great Australian Bight.M ...

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 ...

Soil Degradation
Soil retrogression and degradation are two regressive evolution processes associated with the loss of equilibrium of a stable soil. Retrogression is primarily due to soil erosion and corresponds to a phenomenon where succession reverts the land to its natural physical state. Degradation is an evolution, different from natural evolution, related to the local climate and vegetation. It is due to the replacement of primary plant communities (known as climax vegetation) by the secondary communities. This replacement modifies the humus composition and amount, and affects the formation of the soil. It is directly related to human activity. Soil degradation may also be viewed as any change or ecological disturbance to the soil perceived to be deleterious or undesirable.Johnson, D.L., S.H. Ambrose, T.J. Bassett, M.L. Bowen, D.E.

Plant Taxonomy
Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. It is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things). Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two. In practice, "plant systematics" involves relationships between plants and their evolution, especially at the higher levels, whereas "plant taxonomy" deals with the actual handling of plant specimens. The precise relationship between taxonomy and systematics, however, has changed along with the goals and methods employed. Plant taxonomy is well known for being turbulent, and traditionally not having any close agreement on circumscription and placement of taxa. See the list of systems of plant taxonomy. Background Classification systems serve the purpose of grouping organisms by characteristics common to each group. Plants are distinguished from animals by various trai ...

Alpine National Park
The Alpine National Park is a national park located in the Central Highlands and Alpine regions of Victoria, Australia. The national park is located northeast of Melbourne. It is the largest National Park in Victoria, and covers much of the higher areas of the Great Dividing Range in Victoria, including Victoria's highest point, Mount Bogong at and the associated subalpine woodland and grassland of the Bogong High Plains. The park's north-eastern boundary is along the border with New South Wales, where it abuts the Kosciuszko National Park. On 7 November 2008 the Alpine National Park was added to the Australian National Heritage List as one of eleven areas constituting the Australian Alps National Parks and Reserves. Ecology Ecologically, Alpine refers to areas where the environment is such that trees are unable to grow and vegetation is restricted to dwarfed shrubs, alpine grasses and ground-hugging herbs. In Victoria this is roughly those areas above . Below this is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kosciuszko National Park
The Kosciuszko National Park () is a national park and contains mainland Australia's highest peak, Mount Kosciuszko, for which it is named, and Cabramurra, the highest town in Australia. Its borders contain a mix of rugged mountains and wilderness, characterised by an alpine climate, which makes it popular with recreational skiers and bushwalkers. The park is located in the southeastern corner of New South Wales, southwest of Sydney, and is contiguous with the Alpine National Park in Victoria to the south, and the Namadgi National Park in the Australian Capital Territory to the northeast. The larger towns of Cooma, Tumut and Jindabyne lie just outside and service the park. The waters of the Snowy River, the Murray River, the Murrumbidgee River, and the Gungarlin River all rise in this park. Other notable peaks in the park include Gungartan, Mount Jagungal, Bimberi Peak and Mount Townsend. On 7 November 2008, the Park was added to the Australian National Heritage List as on ...

Bogong High Plains
The Bogong High Plains (), part of the Victorian Alps of the Great Dividing Range, are a section of plains located in the Alpine National Park in the Australian state of Victoria and are situated south of Mount Bogong. In winter this area is one of the largest snow-covered areas in Australia and can be easily accessed from the Hotham Alpine Resort and Falls Creek ski resort. The area is very popular for both summer and winter time activities. Ski touring and all types of cross-country skiing are possible through most winter months. A trail called Australian Alps Walking Track is popular for hiking in summer and cross-country skiing in winter. Mountain biking and bushwalking are common in summer. Local towns and villages provide the best possibility for exploring the areas, including Mount Beauty and Harrietville. History The traditional custodians of the land surrounding the Bogong High Plains are the indigenous Australian Bidawal, Dhudhuroa, GunaiKurnai and NindiNgudjam ...

Kiewa Hydroelectric Scheme
The Kiewa Hydroelectric Scheme is the largest hydro-electric scheme in the Australian States and territories of Australia, state of Victoria (Australia), Victoria and the second-largest in mainland Australia after the Snowy Mountains Scheme. The scheme is situated in the Australian Alps in north-eastern Victoria about from Melbourne and is wholly owned by AGL Energy. The scheme was originally constructed between 1938 and 1961 by the State Electricity Commission of Victoria although it was privatised in the 1990s. The scheme was originally developed solely for electricity generation, unlike the Snowy Mountains Scheme, which was also intended to direct water west of the Snowy Mountains for purposes of irrigation. History Inception Hydroelectric power generation in the Mount Bogong–Mount Feathertop, Feathertop–Mount Hotham, Hotham area was first proposed by a private company known as the Victorian Hydro-Electric Company (VHEC), established in 1911. The Kiewa River was the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siltation
Siltation, is water pollution caused by particulate terrestrial clastic material, with a particle size dominated by silt or clay. It refers both to the increased concentration of suspended sediments and to the increased accumulation (temporary or permanent) of fine sediments on bottoms where they are undesirable. Siltation is most often caused by soil erosion or sediment spill. It is sometimes referred to by the ambiguous term "sediment pollution", which can also refer to a chemical contamination of sediments accumulated on the bottom, or to pollutants bound to sediment particles. Although "siltation" is not perfectly stringent, since it also includes particle sizes other than silt, it is preferred for its lack of ambiguity. Causes The origin of the increased sediment transport into an area may be erosion on land or activities in the water. In rural areas, the erosion source is typically soil degradation by intensive or inadequate agricultural practices, leading to soil eros ...

Soil Erosion
Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, and animals (including humans). In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolean) erosion, zoogenic erosion and anthropogenic erosion such as tillage erosion. Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of topsoil. The loss of soil from farmland may be reflected in reduced crop production potential, lower surface water quality and damaged drainage networks. Soil erosion could also cause sinkholes. Human activities have increased by 10–50 times the rate at which erosion is occurring world-wide. Excessive (or accelerated) erosion causes both "on-site" and "off-site" problems. On- ...
