Karri Forest
Karri forest is a tall open forest type dominated by ''Eucalyptus diversicolor'' (karri), one of the tallest hardwoods in the world. Karri forest occurs only in the south-west corner of the Southwest Botanical Province of Western Australia, in the Warren biogeographic region.Marchant, N. G. (2000) ''Karri forest in microcosm : William Bay National Park.'' Landscope (Como, W.A), Spring 2000, p. 42-47 The Warren region is also known as the Karri Forest Region, but this is a misnomer, as only about half of the region is vegetated with karri forest. From the 1880s onward, karri forest supported timber and firewood industries when access to the forest was improved by a network of the state's railway lines. Small settlements such as Karridale, Deanmill and Pemberton were established around timber mills, and have since become centres for regional tourism. Some of the remaining areas of karri forest are now protected in reserves such as Brockman National Park, Warren National Par ...

Deanmill, Western Australia
Deanmill is a historic timber town located in the South West (Western Australia), South West region of Western Australia, near Manjimup, Western Australia, Manjimup. Its postcode is 6258. History After the Government Trading Concerns Act 1912 was passed in December of that year, several State-operated businesses were established. One of these was State Saw Mills, which commenced with purchasing the South-West Timber Hewers' Co-operative for £80,000. Construction on the State's Number 1 sawmill, later called Deanmill, began in 1913, as did construction of the Number 2 and 3 mills at Big Brook, later called Pemberton, Western Australia, Pemberton. The mills cost an estimated £138,000, and were to provide timber Railroad tie, railway sleepers for the Trans-Australian Railway. Construction of the mills was delayed by heavy rainfall, and the railway sleepers were delivered late. Other problems included shipping disputes and the Commonwealth government's price for sleepers.

Mediterranean Forests, Woodlands, And Scrub In Australia
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide. The Mediterranean Sea enc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 p ...

Forests Of Western Australia
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are i ...

Leaf Litter
Plant litter (also leaf litter, tree litter, soil litter, litterfall or duff) is dead plant material (such as leaves, bark, needles, twigs, and cladodes) that have fallen to the ground. This detritus or dead organic material and its constituent nutrients are added to the top layer of soil, commonly known as the litter layer or O horizon ("O" for "organic"). Litter is an important factor in ecosystem dynamics, as it is indicative of ecological productivity and may be useful in predicting regional nutrient cycling and soil fertility. Characteristics and variability Litterfall is characterized as fresh, undecomposed, and easily recognizable (by species and type) plant debris. This can be anything from leaves, cones, needles, twigs, bark, seeds/nuts, logs, or reproductive organs (e.g. the stamen of flowering plants). Items larger than 2 cm diameter are referred to as coarse litter, while anything smaller is referred to as fine litter or litter. The type of litterfall is ...
