Dryandra Woodland
The Dryandra Woodland National Park is a national park in Western Australia within the shires of Cuballing, Williams and Wandering, about south-east of Perth and north-west of the town of Narrogin. It is a complex of 17 distinct blocks managed by the Western Australian Department of Biodiversity, Conservation and Attractions and spread over approximately separated by areas of agricultural land. The area is considered to be one of the state's major conservation areas, and although it is far from pristine due to its history of logging operations, a number of species of threatened fauna are rebuilding populations through the removal of introduced predators such as foxes and feral cats. The combined area of the woodland is , with individual blocks ranging in size from to . Part of Dryandra Woodland is listed on the Register of the National Estate by the Australian Heritage Council. In addition to the area's use as a wildlife refuge, it has anthropological significance wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noongar Language
Noongar (), also Nyungar (), is an Australian Aboriginal languages, Australian Aboriginal language or dialect continuum, spoken by some members of the Noongar community and others. It is taught actively in Australia, including at schools, universities and through public broadcasting. The Country (Indigenous Australians), country of the Noongar people is the southwest corner of Western Australia. Within that region, many Noongar words have been loanword, adopted into Australian English, particularly names of plants and animals. Noongar was first recorded in 1801 by Matthew Flinders, who made a number of word lists. Varieties It is generally agreed that there was no single, standard Noongar (or Nyungar) language before European settlement: it was a Linkage (linguistics), subgroup (or possibly a dialect continuum) of closely related languages, whose speakers were differentiated geographically and, in some cases, by cultural practices. The dialects merged into the modern Noonga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dryandra Logo
''Banksia'' ser. ''Dryandra'' is a series of 94 species of shrub to small tree in the plant genus ''Banksia''. It was considered a separate genus named ''Dryandra'' until early 2007, when it was merged into ''Banksia'' on the basis of extensive molecular and morphological evidence that ''Banksia'' was paraphyletic with respect to ''Dryandra''. Taxonomy The dryandras were named in honour of Swedish botanist Jonas C. Dryander. The first specimens of a ''Dryandra'' were collected by Archibald Menzies, surgeon and naturalist to the Vancouver Expedition. At the request of Joseph Banks, Menzies collected natural history specimens wherever possible during the voyage. During September and October 1791, while the expedition were anchored at King George Sound, he collected numerous plant specimens, including the first specimens of '' B. sessilis'' (Parrotbush) and '' B. pellaeifolia''. Upon Menzies' return to England, he turned his specimens over to Banks; as with most other s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eucalyptus Accedens
''Eucalyptus accedens'', commonly known as smooth bark wandoo or powderbark wandoo is a species of tree endemic to the south-west of Western Australia. Although the common names suggest it is similar to wandoo, ('' Eucalyptus wandoo''), the two species are very different botanically. The bark of ''E. accedens'' has talc-like powder, at least on the protected side of the trunk and the tree usually grows on laterite in higher places. Description ''Eucalyptus accedens'' is a tree which typically grows to a height of with branches high up the trunk and forms a lignotuber. Its diameter can be as large as and hollows will readily form in dead branches or where limbs have fallen. The smooth bark is notable for being covered in a talc-like powder. It is pale-white when fresh, turning a shade of orange before being shed again. The adult leaves are arranged alternately and are the same dull blue-green colour on both sides. The blade is in length and wide with a lanceolate shape and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalyptus Wandoo
''Eucalyptus wandoo'', commonly known as wandoo, dooto, warrnt or wornt and sometimes as white gum, is a small to medium-sized tree that is endemic to the southwest of Western Australia. It has smooth bark, lance-shaped adult leaves, flower buds in groups of nine to seventeen, white flowers and conical to cylindrical fruit. It is one of a number of similar ''Eucalyptus'' species known as '' wandoo''. ''E.wandoo'' was first described in 1934 by the Australian botanist William Faris Blakely in his book ''A Key to the Eucalypts'' using material collected by the English collector Augustus Frederick Oldfield from a sand plain along the Kalgan River. , Plants of the World Online lists ''Eucalyptus redunca'' var. ''elata'' as a taxonomic synonym of ''E.wandoo''. The range of the tree extends from Morawa in the north extending south through the Darling Range down to around the Stirling Range to the south coast near the Pallinup River.

Eucalyptus
''Eucalyptus'' () is a genus of more than 700 species of flowering plants in the family Myrtaceae. Most species of ''Eucalyptus'' are trees, often Mallee (habit), mallees, and a few are shrubs. Along with several other genera in the tribe Eucalypteae, including ''Corymbia'' and ''Angophora'', they are commonly known as eucalypts or "gum trees". Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard, or stringy and leaves that have oil Gland (botany), glands. The sepals and petals are fused to form a "cap" or Operculum (botany), operculum over the stamens, hence the name from Greek ''eû'' ("well") and ''kaluptós'' ("covered"). The fruit is a woody Capsule (botany), capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are Indigenous (ecology), native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Many eucalypt species have adapted to wildfire, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southwest Botanical Province
Southwest Australia is a biogeographic region in Western Australia. It includes the Mediterranean-climate area of southwestern Australia, which is home to a diverse and distinctive flora and fauna.

Biogeography
Biogeography is the study of the species distribution, distribution of species and ecosystems in geography, geographic space and through evolutionary history of life, geological time. Organisms and biological community (ecology), communities often vary in a regular fashion along geographic gradients of latitude, elevation, allopatric speciation, isolation and habitat species-area curve, area. 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 Natural environment, environments. Biogeography is an integrative field of inquiry that unites concepts and information from ecology, evolutionary biology, taxonomy (bio ...

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. Beecham, Brett (2001). "Avon Wheatbelt 2 (AW2 - Re-juvenated Drainage subregion)" in ''A Biodiversity Audit of Western Australia’s 53 Biogeographical Subregions in 2002''.

Laterite
Laterite is a soil 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. The process of formation is called laterization. Tropical weathering 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 ...
