Lake Bryde-East Lake Bryde
Lake Bryde-East Lake Bryde is a DIWA-listed freshwater wetland system located in the Great Southern region of Western Australia. The system consists of two lakes: Lake Bryde, with an area of ; and East Lake Bryde, with an area of about . They are located at the head of a chain of lakes that extend to Lake Magenta, and ultimately form part of the Swan- Avon drainage system. Description The system is situated in the Shire of Kent, south-west of Newdegate. It in part of the Western Mallee biogeographic subregion of the Mallee region of the South West Botanic Province. The Lake Bryde-East Lake Bryde system contains the only shrub-dominated lake bed vegetation community in the province. This community, which consists mainly of the critically endangered ''Muehlenbeckia horrida'' subsp. ''abdita'' (Remote Thorny Lignum) and ''Tecticornia verrucosa'', has been declared a critically endangered threatened ecological community under the name "Bryde". The lakes experience a regular ...

Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about five y ...

List Of Lakes Of Australia
Natural freshwater lakes in Australia are rare due to the general absence of glacial and tectonic activity in Australia. Types Most lakes in Australia fall within one of five categories. Excluding lakes created by 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 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 lakes in the flat desert regions of the country lacking organised drainage; and * lakes created in volcanic remnants.

Hydrology
Hydrology () is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources, and environmental watershed sustainability. A practitioner of hydrology is called a hydrologist. Hydrologists are scientists studying earth or environmental science, civil or environmental engineering, and physical geography. Using various analytical methods and scientific techniques, they collect and analyze data to help solve water related problems such as environmental preservation, natural disasters, and water management. Hydrology subdivides into surface water hydrology, groundwater hydrology (hydrogeology), and marine hydrology. Domains of hydrology include hydrometeorology, surface hydrology, hydrogeology, drainage-basin management, and water quality, where water plays the central role. Oceanography and meteorology are not included because water is only one of many important aspects within those fields. H ...

Water Table
The water table is the upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with water. It can also be simply explained as the depth below which the ground is saturated. The water table is the surface where the water pressure head is equal to the atmospheric pressure (where gauge pressure = 0). It may be visualized as the "surface" of the subsurface materials that are saturated with groundwater in a given vicinity. The groundwater may be from precipitation or from groundwater flowing into the aquifer. In areas with sufficient precipitation, water infiltrates through pore spaces in the soil, passing through the unsaturated zone. At increasing depths, water fills in more of the pore spaces in the soils, until a zone of saturation is reached. Below the water table, in the phreatic zone (zone of saturation), layers of permeable rock that yield groundwater are called aquifers. In less permeable soils, such as ...

Department Of Conservation And Land Management
The Department of Conservation and Land Management (CALM) was a department of the Government of Western Australia that was responsible for implementing the state's conservation and environment legislation and regulations. It was created by the ''Conservation and Land Management Act 1984'', also known as the ''CALM Act'', which is still in force . The Department of Conservation and Land Management was responsible from 22 March 1985 to 30 June 2006 for protecting and conserving the State of Western Australia’s environment; this included managing the state's national parks, marine parks, conservation parks, state forests, timber reserves and nature reserves. The Conservation Commission of Western Australia, responsible for assessing and auditing the performance of the department, was also created by the ''CALM Act''. Now ( renamed the Conservation and Parks Commission), its functions have broadened, with its purpose stated as "to act as an independent and trusted community stew ...

Threatened Ecological Community
Threatened ecological community is a term used in Australia for ecosystems that are in danger of being lost due to some threatening process. Federally, threatened ecological communities are identified and protected under the ''Environment Protection and Biodiversity Conservation Act 1999''. Some states also have legislation to cover these. In New South Wales, for example, ecosystems may be gazetted as threatened under the ''Threatened Species Conservation Act 1995'', and in Western Australia they may be protected under the ''Wildlife Conservation Act 1950 The ''Wildlife Conservation Act 1950'' is an act of the Western Australian Parliament that provides the statute relating to conservation and legal protection of flora and fauna.

Tecticornia Verrucosa
''Tecticornia verrrucosa'' is a species of plant that is succulent and halophyte (salt tolerant). This plant was a member of the Chenopodiaceae, which are now included in family Amaranthaceae. ''T. verrucosa'' was first described in 1972 by Paul Wilson. It is an annual or short-lived perennial which grows to 40 cm high, which branches at the occasionally woody base. The inflorescence is a set of opposite and decussate lateral sessile spikes, at right angles to the branch. They are cylindrical and 10–20 mm long by 6 mm diam. The flowers are triads with free tepals below and slightly united above. It grows on coastal mud flats, slightly saline clay pans, and inland freshwater. The Walmajarri people of the southern Kimberley call this plant ''Mungily.'' References verrucosa ''Verrucosa'' is a genus of Araneidae, orb-weaver spiders first described by Henry Christopher McCook, Henry McCook in 1888. It contains almost fifty described species, most of which live in Sout ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
