Eucalyptus Pendens
''Eucalyptus pendens'', commonly known as the Badgingarra weeping mallee, is a mallee that is native to a small area on the west coast of Western Australia. Description The mallee typically grows to a height of and has a slender and pendulous habit. It has smooth pale coloured bark and blooms between August and November producing white-cream flowers. The smooth bark is pink to grey in colour with pith glands present. The disjunct adult leaves have a lanceolate shape and are acute and basally tapered. The coriaceous or thick leaves have a dull green, concolorous appearance and are supported by narrowly flattened petioles. It forms simple axillary conflorescences with seven to eleven flowered umbellasters on terete angular peduncles. The buds are clavate followed by cylindrical to ovoid fruits with a depressed disc and enclosed valves. Taxonomy The species was first formally classified by the botanist Ian Brooker in 1972 in the article ''Four new taxa of Eucalyptus from Wester ...

Ian Brooker
Murray Ian Hill Brooker AM (2 June 1934 – 25 June 2016), better known as Ian Brooker, was an Australian botanist. He was widely recognised as the leading authority on the genus ''Eucalyptus''. Ian Brooker was born in Adelaide, South Australia on 2 June 1934. He obtained a B.Ag.Sc. from the University of Adelaide, and a MSc and D.Sc. from the Australian National University in Canberra. He worked with the Soil Conservation Branch of the Department of Agriculture in South Australia from 1957 to 1963; then joined the Department of Botany at the Australian National University until 1969; and then spent a year with the Western Australian Herbarium. In 1970, Brooker joined the Forest Research Institute in Canberra, now part of CSIRO. His research since then has specialised in the genus ''Eucalyptus'', especially its taxonomy. He travelled widely throughout Australia collecting specimens, and published 100 research papers, 180 leaflets, and four books, and is the principal author o ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Myrtales Of Australia
The Myrtales are an order of flowering plants placed as a sister to the eurosids II clade as of the publishing of the ''Eucalyptus grandis'' genome in June 2014. The APG III system of classification for angiosperms still places it within the eurosids. This finding is corroborated by the placement of the Myrtales in the Malvid clade by the One Thousand Plant Transcriptomes Initiative. The following families are included as of APGIII: * Alzateaceae S. A. Graham * Combretaceae R. Br. ( leadwood family) * Crypteroniaceae A. DC. * Lythraceae J. St.-Hil. ( loosestrife and pomegranate family) * Melastomataceae Juss. (including Memecylaceae DC.) * Myrtaceae Juss. (myrtle family; including Heteropyxidaceae Engl. & Gilg, Psiloxylaceae Croizat) * Onagraceae Juss. (evening primrose and Fuchsia family) * Penaeaceae Sweet ex Guill. (including Oliniaceae Arn., Rhynchocalycaceae L. A. S. Johnson & B. G. Briggs) * Vochysiaceae A. St.-Hil. The Cronquist system gives essentially the same co ...

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] |

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 ...

Moora, Western Australia
Moora is a townsite located 177 km north of Perth in the Wheatbelt region of Western Australia. Moora was one of the original stations on the Midland railway line to Walkaway, and the townsite was gazetted in 1895. At the , Moora had a population of 1,755. Commercial area The town is the largest wheat belt town between Geraldton and Perth. The town provides facilities and services such as commercial banks, schools, commerce and retail sectors, community recreational facilities; plus a Pharmacy, Dentist, Doctors and District Hospital. The surrounding areas produce wheat and other cereal crops. The town is a receival site for Cooperative Bulk Handling. Natural disasters The town was left underwater in 1932 when heavy rainfall inundated the town, causing severe flooding. The town was left isolated as both rail lines and roads had portions washed away. Over half the town was submerged to a depth of , and once the waters receded, was left under a thick coating of mud.

Dandaragan, Western Australia
Dandaragan is a small town in the Wheatbelt region of Western Australia. The name of Dandaragan was first recorded in 1850 as the name of a nearby gulley and spring or watering hole known as Dandaraga spring. The word is Indigenous Australian in origin and is thought to mean ''good kangaroo country''. The first recorded land lease was to William Brockman in 1848; he had a land lease at Muchamulla Springs. James Drummond settled in the area in 1850 and established a farm. A police station was built later and the townsite was gazetted in 1958.

Coorow, Western Australia
Coorow is a town in the Mid West region of Western Australia, north of Perth. History The townsite of Coorow was gazetted in 1893. Its name is derived from the Aboriginal name of a nearby spring, first recorded in 1872. The meaning of the name may be from the word "Curro", which is the Aboriginal word for a variety of ''Portulaca''; another source gives it as "many mists". The town experienced some flooding in 1918 following a deluge of of rain overnight. The Moore River broke its banks and caused much more severe flooding downstream at Moora. After rapid growth through the early 1920s local settlers began to seek obtaining a hotel licence for the town in 1927. The licence was granted in 1929 to Alexander Gloster who put forward a tender of £1,750, and submitted his plans for approval. The hotel was erected at a cost of £13,000 and constructed of cement blocks and brick. The two storey building held fifteen rooms for accommodation on the top floor and more accommodation ...

Wheatbelt (Western Australia)
The Wheatbelt is one of nine regions of Western Australia defined as administrative areas for the state's regional development, and a vernacular term for the area converted to agriculture during colonisation. It partially surrounds the Perth metropolitan area, extending north from Perth to the Mid West region, and east to the Goldfields–Esperance region. It is bordered to the south by the South West and Great Southern regions, and to the west by the Indian Ocean, the Perth metropolitan area, and the Peel region. Altogether, it has an area of (including islands). The region has 42 local government authorities, with an estimated population of 75,000 residents. The Wheatbelt accounts for approximately three per cent of Western Australia's population. Ecosystems The area, once a diverse ecosystem, reduced when clearing began in the 1890s with the removal of plant species such as eucalypt woodlands and mallee, is now home to around 11% of Australia's critically end ...
