Warren Bioregion
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 ...

Pemberton, Western Australia
Pemberton is a town in the South West region of Western Australia, named after original settler Pemberton Walcott. History The region was originally occupied by the Bibbulmun people who knew the area as Wandergarup, which in their language meant 'plenty of water'. Following an expedition to the area in 1861 by Edward Reveley Brockman, his brother-in-law Gerald de Courcy Lefroy and his uncle Pemberton Walcott, in 1862 Brockman established Warren House homestead and station on the Warren River; Walcott, after whom the town would be named, established ''Karri Dale'' farm on the northern outskirts of the later townsite; and Lefroy established a farm and flour mill on Lefroy Brook (the current site of the 100 Year Forest). Walcott remained until at least 1867. By 1868 he was at Dwalganup Station near Boyup Brook, and in 1872 ''Karri Dale'' was for sale, marketed as a "four-roomed brick cottage, stockyards, cattle shed, good garden - stocked with fruit trees and permanent running ...

Yilgarn Craton
The Yilgarn Craton is a large craton that constitutes the bulk of the Western Australian land mass. It is bounded by a mixture of sedimentary basins and Proterozoic fold and thrust belts. Zircon grains in the Jack Hills, Narryer Terrane have been dated at ~4.27 Ga, with one detrital zircon dated as old as 4.4 Ga. The Murchison Province of the craton contains the oldest dated meteorite impact crater, at 2229 ± 5 Ma. Geology The Yilgarn Craton appears to have been assembled between ~2.94 and 2.63 Ga by the accretion of a multitude of formerly present blocks or terranes of existing continental crust, most of which formed between 3.2 Ga and 2.8 Ga. This accretion event is recorded by widespread granite and granodiorite intrusions, which comprise over 70% of the Yilgarn craton; voluminous tholeiitic basalt and komatiite volcanism; regional metamorphism and deformation as well as the emplacement of the vast majority of the craton's endowment in gold mineralisation.

Metamorphic Rock
Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock ( protolith) is subjected to temperatures greater than and, often, elevated pressure of or more, causing profound physical or chemical changes. During this process, the rock remains mostly in the solid state, but gradually recrystallizes to a new texture or mineral composition. The protolith may be an igneous, sedimentary, or existing metamorphic rock. Metamorphic rocks make up a large part of the Earth's crust and form 12% of the Earth's land surface. They are classified by their protolith, their chemical and mineral makeup, and their texture. They may be formed simply by being deeply buried beneath the Earth's surface, where they are subject to high temperatures and the great pressure of the rock layers above. They can also form from tectonic processes such as continental collisions, which cause horizontal pressure, friction, and dis ...

IBRA 6
The Interim Biogeographic Regionalisation for Australia (IBRA) is a biogeographic regionalisation of Australia developed by the Australian government's Department of Sustainability, Environment, Water, Population, and Communities. It was developed for use as a planning tool, for example for the establishment of a national reserve system. The first version of IBRA was developed in 1993–94 and published in 1995. Within the broadest scale, Australia is a major part of the Australasia biogeographic realm, as developed by the World Wide Fund for Nature. Based on this system, the world is also split into 14 terrestrial habitats, of which eight are shared by Australia. The Australian land mass is divided into 89 bioregions and 419 subregions. Each region is a land area made up of a group of interacting ecosystems that are repeated in similar form across the landscape. IBRA is updated periodically based on new data, mapping improvements, and review of the existing scheme. The most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Denmark, Western Australia
Denmark is a coastal town located on Wilson Inlet in the Great Southern region of Western Australia, south-south-east of the state capital of Perth. At the 2016 census, Denmark had a population of 2,558; however, the population can be several times the base population during tourist seasons. History '' 't Landt van de Leeuwin'' (Leeuwin's Land) was the original Dutch name for the area from King George Sound to the Swan River. It was named after the Dutch East Indiaman , which sighted the coast from Hamelin Bay to Point D'Entrecasteaux in 1622. The coastline of the Denmark area was observed in 1627 by the Dutchman François Thijssen, captain of the ship (The Golden Seahorse), who sailed to the east as far as Ceduna in South Australia and back. Captain Thijssen had seen the south coast of Australia and charted about of it between Cape Leeuwin and the Nuyts Archipelago. Two centuries later, when the first Europeans entered the lands around the present Denmark, the ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walpole, Western Australia
Walpole is a town in the south-western region of Western Australia, located approximately south southeast of Perth, and west of Denmark. Location and description Walpole lies very close to the northern point of the Walpole Inlet, from which it takes its name. The inlet in turn is named for the Walpole River, discovered in 1831 by Captain Thomas Bannister, and named by Governor Stirling for Captain W. Walpole, with whom he had served aboard HMS Warspite in 1808. The first European settlers to arrive in the area were Pierre Bellanger and his family in 1909. They travelled aboard the ''Grace Darling'' from Albany to take up of land. Land in the Walpole area was reserved for a national park in 1910, and the area subsequently became a popular holiday destination. Major development began to occur in the 1930s as part of the land settlement scheme. The railway reached Nornalup in 1929, and the Walpole town site was gazetted in 1933. The local electricity grid is remote and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Augusta, Western Australia
Augusta is a town on the south-west coast of Western Australia, where the Blackwood River emerges into Flinders Bay. It is the nearest town to Cape Leeuwin, on the furthest southwest corner of the Australian continent. In the it had a population of 1,091; by 2016 the population of the town was 1,109 (excluding East Augusta). The town is within the Shire of Augusta-Margaret River local government area, and is in the Leeuwin Ward. It is connected by public transport to Perth via Transwa coach service SW1. Augusta was a summer holiday town for many during most of the twentieth century, but late in the 1990s many people chose to retire to the region for its cooler weather. As a consequence of this and rising land values in the Augusta-Margaret River area, the region has experienced significant social change. History Noongar peoples, the Aboriginal Australian peoples of south-western Australia, inhabited the area for an estimated 45,000 years before the arrival of European sett ...

John Stanley Beard
John Stanley Beard (15 February 1916 – 17 February 2011) was a British-born forester and ecologist who resided in Australia. Beard studied at the University of Oxford where he completed his doctoral thesis on tropical forestry. While working with the Forestry Division in Trinidad and Tobago during the 1940s, Beard developed a system of forest classification for Tropical America and described the forests of Trinidad, Tobago, and the Lesser Antilles; these descriptions remain standard references on the topics. After leaving Trinidad, Beard moved to South Africa and then to Australia, where he produced an extensive series of vegetation maps covering much of the country. His extensive surveys of Western Australia set standards for understanding regional floristic zones and biogeographical areas for the whole state. He was the main author of the 1964–1981 explanatory notes to the mapping project of the '' Vegetation Survey of Western Australia'', which involved travelling s ...

Manjimup, Western Australia
Manjimup is a town in Western Australia, south of the state capital, Perth. The town of Manjimup is a regional centre for the largest shire in the South West region of Western Australia. At the 2016 census, Manjimup had a population of 4,349. History Manjimup was named after the Noongar words "Manjin" (a broad-leafed edible reed) and " up" (meeting place, or place of). Manjimup was first settled by timber cutter Thomas Muir, who took up land near the present town site in 1856. It was declared a town in 1910, and a railway from Perth was completed in 1911. The population expanded when Manjimup became part of the post-World War I Group Settlement Scheme. The Group Settlement Scheme was largely unsuccessful because the land was difficult to clear and many of the new settlers were not experienced farmers. The settlers who stayed became dairy farmers, which ended during the 1930s Great Depression when the price of butterfat collapsed. Economy Industry Timber is the town's major ...
