Cranbrook, Western Australia
Cranbrook is a small town in the Shire of Cranbrook in the Great Southern region of Western Australia between Katanning, Kojonup and Mount Barker, situated 320 km south of Perth. It is billed as "The Gateway to the Stirlings", referring to the nearby Stirling Range National Park. At the 2006 census, Cranbrook had a population of 280. The settlement grew after it was one of the original railway stations on the Great Southern Railway when the railway opened in 1889, and was gazetted a townsite in 1899. The name is taken from the town of Cranbrook in Kent, England, about 65 kilometres south east of London. It is believed to have been named by Mr J A Wright, who was manager of the Western Australian Land Company which built the railway. The town is a Cooperative Bulk Handling The CBH Group (commonly known as CBH, an acronym for Co-operative Bulk Handling), is a grain growers' cooperative that handles, markets and processes grain from the wheatbelt of Western Aust ...

Avon Wheatbelt
The Avon Wheatbelt is a bioregion in Western Australia. It has an area of . It is considered part of the larger Southwest Australia savanna ecoregion. Geography The Avon Wheatbelt bioregion is mostly a gently undulating landscape with low relief. It lies on the Yilgarn Craton, an ancient block of crystalline rock, which was uplifted in the Tertiary and dissected by rivers. The craton is overlain by laterite deposits, which in places have decomposed into yellow sandplains, particularly on low hills. Steep-sided erosional gullies, known as breakaways, are common.

Plants Described In 1839
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...

Orchids Of Western Australia
Among the many wildflowers in Western Australia, there are around four hundred species of orchids. Early identifications One of the first botanists to study Western Australia was Archibald Menzies, aboard HMS ''Discovery'', who explored King George Sound in 1791. Many of the samples (including orchids) were lost in the return to England, but those that did survive were documented in ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'', published by Robert Brown in 1810. The first three orchids from Western Australia to be named were ''Caladenia menziesii'' (now '' Leptoceras menziesii''), '' Caladenia flava'', and ''Diuris longifolia''. In 1802 Robert Brown himself collected 500 specimens of flora from Western Australia, including: * ''Diuris emarginata'' var. ''emarginata'' * ''Diuris emarginata'' var. ''pauciflora'' *'' Diuris setacea'' *'' Epiblema grandiflorum'' *''Microtis alba'' *'' Microtis media'' *'' Microtis pulchella'' *'' Prasophyllum gibbosum'' *''Prasoph ...

Endemic Orchids Of Australia
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diuris
''Diuris'', commonly known as donkey orchids, bee orchids, nanny goat orchids or pansy orchids, is a genus of more than sixty species of flowering plants in the orchid family, Orchidaceae and is endemic to Australia, apart from one species endemic to Timor. The name "''Diuris''" refers to the hanging sepals but the common name "donkey orchid", derives from the ear-like petals common to all species. Many have mainly yellow flowers with darker markings and are thought to mimic nectar-producing flowers which open at the same time. Description Orchids in the genus ''Diuris'' are terrestrial, perennial, deciduous, sympodial herbs, usually with a few inconspicuous, fine roots and one or two tubers lacking a protective sheath. The stem is short, erect and unbranched with a leaf-like cataphyll at each node. There are between one and ten grass-like leaves at the base of the plant. The inflorescence is a raceme with a few to many brightly coloured, resupinate flowers on a wiry stalk. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loam
Loam (in geology and soil science) is soil composed mostly of sand (particle size > ), silt (particle size > ), and a smaller amount of clay (particle size < ). By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. These proportions can vary to a degree, however, and result in different types of loam soils: sandy loam, silty loam, clay loam, sandy clay loam, silty clay loam, and loam. In the , textural classification triangle, the only soil that is not predominantly sand, silt, or clay is called "loam". Loam soils generally contain more nutrients, moisture, and |
Laterite
Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate wet and dry periods. Tropical weathering (''laterization'') is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the resulting soils. The majority of the land area containing laterites is between the tropics of Cancer and Capricorn. Laterite has commonly been referred to as a soil type as well as being a rock type. This and further variation in the modes of conceptualizing about laterite (e.g. also as a complete weathering profile or theory about weathering) has led to calls for the term to be abandoned alto ...

Biogeography
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area.Brown University, "Biogeography." Accessed February 24, 2014. . Phytogeography is the branch of biogeography that studies the distribution of plants. Zoogeography is the branch that studies distribution of animals. Mycogeography is the branch that studies distribution of fungi, such as mushrooms. Knowledge of spatial variation in the numbers and types of organisms is as vital to us today as it was to our early human ancestors, as we adapt to heterogeneous but geographically predictable environments. Biogeography is an integrative field of inquiry that unites concepts and information from ecology, evolutionary biology, taxonomy, geology, physical geography, palaeontology, and climatology.Dansereau, Pierre. 1957 ...

Warren (biogeographic Region)
Warren, also known as Karri Forest Region and the Jarrah-Karri forest and shrublands ecoregion, is a biogeographic region in southern Western Australia. Located in the southwest corner of Western Australia between Cape Naturaliste and Albany, it is bordered to the north and east by the Jarrah Forest region. Its defining characteristic is an extensive tall forest of ''Eucalyptus diversicolor'' (karri). This occurs on dissected, hilly ground, with a moderately wet climate. Karri is a valuable timber and much of the karri forest has been logged over, but less than a third has been cleared for agriculture. Recognised as a region under the Interim Biogeographic Regionalisation for Australia (IBRA), and as a terrestrial ecoregion by the World Wide Fund for Nature, it was first defined by Ludwig Diels in 1906. Geography and geology The Warren region is defined as the coastal sandplain between Cape Naturaliste and Albany. Extending from the ocean to the edge of the Yilgarn craton p ...

Mallee (biogeographic Region)
Mallee, also known as Roe Botanical District, is a biogeographic region in southern Western Australia. Located between the Esperance Plains, Avon Wheatbelt and Coolgardie bioregions, it has a low, gently undulating topography, a semi-arid mediterranean climate, and extensive ''Eucalyptus'' mallee vegetation. It has an area of . About half of the region has been cleared for intensive agriculture. Recognised as a region under the Interim Biogeographic Regionalisation for Australia (IBRA), it was first defined by John Stanley Beard in 1980. Geography and geology The Mallee region has a complex shape with tortuous boundaries, but may be roughly approximated as the triangular area south of a line from Bruce Rock to Eyre, but not within 40 kilometres (25 mi) of the south coast, except at its eastern limits. It has an area of about 79000 square kilometres (31000 mi²), making it about a quarter of the South West Botanic Province, 3% of the state, and 1% of Australia. It ...
