Eucalyptus Coronata
''Eucalyptus coronata'', commonly known as the crowned mallee, is a species of mallee that is endemic to a small part of the south coast of Western Australia. It has smooth bark on the trunk and branches, lance-shaped to curved adult leaves, flower buds with pronounced ribs, arranged in groups of three in leaf axils, white to cream-coloured or yellow flowers and conical, prominently ribbed fruit. Description ''Eucalyptus coronata'' is a multi-stemmed mallee that typically grows to a height of and forms a lignotuber. It has smooth pale gray to pale brown bark throughout. The adult leaves are arranged alternately, bluish-green, lance-shaped to curved, long and wide on a petiole long. The flower buds are arranged in groups of three in leaf axils on a flattened peduncle long, the individual buds sessile or on a pedicel up to long. Mature buds are more or less diamond-shaped, long and wide with many pronounced ribs along the sides, and a beaked operculum. Flowering occurs b ...

Fitzgerald River National Park
Fitzgerald River National Park is a national park in the Shires of Ravensthorpe and the Jerramungup in Western Australia, southeast of Perth. The park is recognised on Australia's National Heritage List for its outstanding diversity of native plant species, including many plants which are unique to the local area. Description The park includes the Barren Mountains (East, Middle and West Mount Barren) and Eyre Range and the Fitzgerald River as well as incorporating the Fitzgerald Biosphere. There are 62 plant species which are unique to the park and a further 48 are rarely found elsewhere. Recording almost 40,000 visitors in 2008, the park received $20 million in funding from the federal government's economic stimulus plan with the state government contributing an additional $20 million. The investment is to be used to redevelop and seal of roads within the park, construct a walk trail from Bremer Bay to Hopetoun and upgrade existing recreational facilities. Point Ann is ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

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 ...

Trees Of Australia
The flora of Australia comprises a vast assemblage of plant species estimated to over 30,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (''Banksia''), Myrtaceae (''Eucalyptus'' - gum trees), and Fabaceae ('' Acacia'' - wattle). The arrival of humans around 50,000 years ago and the settlement by Europeans from 1788, has had a significant impact on the flora. The use of fire-stick farming by Aboriginal people led to significant changes in the distribution of plant species over time, and the ...

Eucalypts Of Western Australia
Eucalypt is a descriptive name for woody plants with capsule fruiting bodies belonging to seven closely related genera (of the tribe Eucalypteae) found across Australasia: ''Eucalyptus'', ''Corymbia'', '' Angophora'', ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum''. Taxonomy For an example of changing historical perspectives, in 1991, largely genetic evidence indicated that some prominent ''Eucalyptus'' species were actually more closely related to ''Angophora'' than to other eucalypts; they were accordingly split off into the new genus ''Corymbia''. Although separate, all of these genera and their species are allied and it remains the standard to refer to the members of all seven genera ''Angophora'', ''Corymbia'', ''Eucalyptus'', ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum'' as "eucalypts" or as the eucalypt group. The extant genera ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum'' comprise six kn ... [...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] |
Department Of Environment And Conservation (Western Australia)
The Department of Environment and Conservation (DEC) 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 formed on 1 July 2006 by the amalgamation of the Department of Environment and the Department of Conservation and Land Management. The DEC was separated on 30 June 2013 forming the Department of Parks and Wildlife (DPaW) and the Department of Environment Regulation (DER), which both commenced operations on 1 July 2013. On 1 July 2017 the DER amalgamated with the Department of Water and the Office of the Environmental Protection Authority, to become the Department of Water and Environmental Regulation, while DPaW was merged with other agencies to form the Department of Parks and Wildlife. Status (at dissolution, 30 June 2013) The department was managing more than 285,000 km2, including more than nine per cent of WA's land area: its national parks, mar ...

Declared Rare And Priority Flora List
The Declared Rare and Priority Flora List is the system by which Western Australia's conservation flora are given a priority. Developed by the Government of Western Australia's Department of Environment and Conservation, it was used extensively within the department, including the Western Australian Herbarium. The herbarium's journal, ''Nuytsia'', which has published over a quarter of the state's conservation taxa, requires a conservation status to be included in all publications of new Western Australian taxa that appear to be rare or endangered. The system defines six levels of priority taxa: ;X: Threatened (Declared Rare Flora) – Presumed Extinct Taxa: These are taxa that are thought to be extinct, either because they have not been collected for over 50 years despite thorough searching, or because all known wild populations have been destroyed. They have been declared as such in accordance with the Wildlife Conservation Act 1950, and are therefore afforded legislative protecti ...

Environment Protection And Biodiversity Conservation Act 1999
The ''Environment Protection and Biodiversity Conservation Act 1999'' (Cth) is an Act of the Parliament of Australia that provides a framework for protection of the Australian environment, including its biodiversity and its natural and culturally significant places. Enacted on 17 July 2000, it established a range of processes to help protect and promote the recovery of threatened species and ecological communities, and preserve significant places from decline. The Act is administered by the Department of Agriculture, Water and the Environment. Lists of threatened species are drawn up under the Act, and these lists, the primary reference to threatened species in Australia, are available online through the Species Profile and Threats Database (SPRAT). As an Act of the Australian Parliament, it relies for its constitutional validity upon the legislative powers of the Parliament granted by the Australian Constitution, and key provisions of the Act are largely based on a number ...

Quartzite
Quartzite is a hard, non- foliated metamorphic rock which was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. The nearly pure silica conte ...
