Lepidosperma Effusum
''Lepidosperma effusum'', commonly known as the riverside sword sedge or spreading sword sedge, is an evergreen species of sedge that is native to southwest Western Australia. Description The sedge has a robust and tufted habit typically growing in clumps to a height of and a width of . It is rhizome, rhizomatous and confined to damp areas. It flowers between April and November producing brown coloured flowers. Taxonomy The species was first formally described by English botanist George Bentham in his ''Flora Australiensis'' in 1878. Distribution It occurs along the edges of creeks and streams and around swamps from the Perth region south through the Margaret River region and eastwards to Albany where it grows in sandy or loamy soils. Ecology ''L. effusum'' occupies a hygrophilous ecological niche along with other Lepidosperma species; ''Lepidosperma australe, L.australe'', ''Lepidosperma longitudinale, L. longitudinale'', ''Lepidosperma gladiatum, L. gladiatum'' , ''Lepidosp ...

Walpole-Nornalup National Park
Walpole-Nornalup National Park is a national park in the South West (Western Australia), South West region of Western Australia, south of Perth. It is famous for its towering karri and tingle trees. Eucalyptus jacksonii, Red tingle trees are unique to the Walpole area. The park is part of the larger Walpole Wilderness Area that was established in 2004, an international biodiversity hotspot. History The traditional owners of the area are the Murrum of the Mineng, Minang peoples of the larger Noongar group who have inhabited the region for over 30,000 years. The park is named after the nearby town of Walpole which in turn honours William Walpole, who served alongside James Stirling (Royal Navy officer), James Stirling on HMS ''HMS Warspite (1807), Warspite'' in 1809. The Noongar peoples know the area as Nor-Nor-Nup, meaning the place of the black snake, which was anglicised as Nornalup. The explorer William Nairne Clark visited the area in 1841 and sailed up the Frankland River ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botaurus Poiciloptilus
The Australasian bittern (''Botaurus poiciloptilus''), also known as the brown bittern or matuku hūrepo, and also nicknamed the " bunyip bird", is a large bird in the heron family Ardeidae. A secretive bird with a distinctive booming call, it is more often heard than seen. Australasian bitterns are endangered in both Australia and New Zealand. Taxonomy German zoologist Johann Georg Wagler described the Australasian bittern in 1827. It is one of four similarly-plumaged species in the genus ''Botaurus''. Description The length is from 650 to 750 mm with adults being similar between the sexes while the male is significantly larger. The bird has a deep brown upper surface, mauled with buff on wing coverts; face and eyebrow buff, with dark brown stripe running from bill to erectile plumes at sides of neck. Under surface buff, striped with brown. The face skin is a dull green as are the legs and feet, it possesses a dark brown bill, yellow eyes, and the base of the lower mandible is ...

Angiosperms Of Western Australia
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils are in the f ...

Water And Rivers Commission
The Water and Rivers Commission is a defunct agency of the Government of Western Australia. Established on 1 January 1996, it was set up under the Water and Rivers Commission Act 1995, to administer the Act and other legislation relevant to development and conservation of Western Australia's water resources. It was eventually amalgamated with the Department of Environmental Protection and Western Australia's Keep Australia Beautiful Council to form the Department of Environment. This was later merged with the Department of Conservation and Land Management to form the Department of Environment and Conservation. Water responsibilities were split off into a separate Department of Water and in July 2017, a new Department merging environment regulatory functions with water management was formed, the Department of Water and Environmental Regulation The Department of Water and Environmental Regulation was formed on 1 July 2017, when the Department of Environment Regulation (DER) ...

Brackish
Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root '' brak''. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment (see article on shrimp farms). Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific grav ...

Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frost
Frost is a thin layer of ice on a solid surface, which forms from water vapor in an above-freezing atmosphere coming in contact with a solid surface whose temperature is below freezing, and resulting in a phase change from water vapor (a gas) to ice (a solid) as the water vapor reaches the freezing point. In temperate climates, it most commonly appears on surfaces near the ground as fragile white crystals; in cold climates, it occurs in a greater variety of forms. The propagation of crystal formation occurs by the process of nucleation. The ice crystals of frost form as the result of fractal process development. The depth of frost crystals varies depending on the amount of time they have been accumulating, and the concentration of the water vapor (humidity). Frost crystals may be invisible (black), clear (translucent), or white; if a mass of frost crystals scatters light in all directions, the coating of frost appears white. Types of frost include crystalline frost (hoar fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zephyrarchaea Mainae
''Zephyrarchaea mainae'' is a species of spider, informally known as Main's assassin spider, Albany assassin spider, and the Western archaeid spider. The first of the assassin spider family (Araneae, Archaeidae) found in Western Australia, the species was unknown until its collection at Torndirrup National Park near Albany was published in 1987. Taxonomy Formally described as ''Austrarchaea mainae'' by Norman Platnick in 1991, the spider was nominated as the type species for the Australian endemic genus ''Zephyrarchaea''. This split from the more widely distributed ''Austrarchaea'' was published in 2012, after further specimens were found and collected in nearby areas, along with several other related archaeid species discovered in the region. Comparative analysis of genotyped archaeid species supports the spider's classification as a species, as does the restricted mobility and specialised habitat of populations.

Elachista Strictifica
''Elachista'' is a genus of gelechioid moths described by Georg Friedrich Treitschke in 1833. It is the type genus of the grass-miner moth family (Elachistidae). This family is sometimes (in particular in older sources) circumscribed very loosely, including for example the Agonoxenidae and Ethmiidae which seem to be quite distinct among the Gelechioidea, as well as other lineages which are widely held to be closer to ''Oecophora'' than to ''Elachista'' and are thus placed in the concealer moth family Oecophoridae here. These grass-miners are very small moths with the "feathery" hindwings characteristic of their family. They are essentially found worldwide, except in very cold places and on some oceanic islands; as usual for Gelechioidea, they are most common in the Palearctic however. They usually have at least one, sometimes as many as three light bands running from leading to trailing edge of their forewing uppersides. Some species, however, have upper forewings that are most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
