Mount Field National Park
Mount Field National Park is a national park in Tasmania, Australia, 64 km northwest of Hobart, Australia, Hobart. The landscape ranges from eucalyptus temperate rainforest to alpine moorland, rising to 1,434 metres (4,705 ft) at the summit of Mount Field West (Tasmania), Mount Field West. History Mount Field National Park was founded in 1916, making it, along with Freycinet National Park, Tasmania's oldest national park. The area around Russell Falls has been protected for its natural beauty since 1885, when it was set aside as Tasmania's first nature reserve. The last known wild thylacine was captured in the region in 1933. The reserve was called "National Park" before 1946, but was officially renamed to its present name in 1947. Etymology Mount Field National Park was named for Judge Barron Field (author), Barron Field, who visited Tasmania as an itinerant judge in 1819 and 1821.

Mount Wellington (Tasmania)
Mount Wellington, also known as kunanyi () in palawa kani and gazetted as kunanyi / Mount Wellington, is a mountain in the south-east of Tasmania, Australia. It is the summit of the Wellington Range and is within Wellington Park reserve. Hobart, Tasmania's capital city, is located at the foot of the mountain. The mountain rises above sea level and is frequently covered by snow, at times even in summer, and the lower slopes are thickly forested, but crisscrossed by many walking tracks and a few fire trails. There is also a sealed narrow road to the summit, about from Hobart central business district. An enclosed lookout near the summit has views of the city below and to the east, the Derwent estuary, and also glimpses of the World Heritage Area nearly west. From Hobart, the most distinctive feature of Mount Wellington is the cliff of dolerite columns known as the Organ Pipes.

Flora Of Tasmania
The biodiversity of Tasmania is of Biology, biological and Paleoecology, paleoecological interest. A state of Australia, it is a large Australasia, South Pacific archipelago of one large main island and a range of smaller islands. The terrain includes a variety of reefs, atolls, small islands, and a variety of Topography, topographical and Edaphology, edaphic regions on the largest island, all of which promote the development of concentrated biodiversity. During long periods geographically and genetically isolated, it is known for its unique flora and fauna. The region's Oceanic climate, climate is oceanic. Evolution The marine fauna of the period, separate from that of the southwest Pacific, was distinguished as the "Maori province". Gondwana began its fragmentation in the middle and upper Jurassic, and the arrival of benthic invertebrate fauna is visible in fossil deposits. The Cretaceous marked the appearance of marine invertebrate fauna of southern origin. It was then that an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asterales Of Australia
Asterales ( ) is an order of dicotyledonous flowering plants that includes the large family Asteraceae (or Compositae) known for composite flowers made of florets, and ten families related to the Asteraceae. While asterids in general are characterized by fused petals, composite flowers consisting of many florets create the false appearance of separate petals (as found in the rosids). The order is cosmopolitan (plants found throughout most of the world including desert and frigid zones), and includes mostly herbaceous species, although a small number of trees (such as the ''Lobelia deckenii'', the giant lobelia, and ''Dendrosenecio'', giant groundsels) and shrubs are also present. Asterales are organisms that seem to have evolved from one common ancestor. Asterales share characteristics on Morphology (biology), morphological and biochemical levels. Synapomorphies (a character that is shared by two or more groups through evolutionary development) include the presence in the pl ...

Olearia
''Olearia'', most commonly known as daisy-bush, is a genus of flowering plants belonging to the family Asteraceae, the largest of the flowering plant families in the world. Olearia are found in Australia, New Guinea and New Zealand. The genus includes herbaceous plants, shrubs and small trees. The latter are unusual among the Asteraceae and are called tree daisies in New Zealand. All bear the familiar daisy-like composite flowerheads in white, pink, mauve or purple. Description Plants in the genus ''Olearia'' are shrubs of varying sizes, characterised by a composite flower head arrangement with single-row ray florets enclosed by small overlapping bracts arranged in rows. The flower petals are more or less equal in length. The centre of the bi-sexual floret is disc shaped and may be white, yellowish or purplish, generally with 5 lobes. Flower heads may be single or clusters in leaf axils or at the apex of branchlets. Leaves may be smooth, glandular or with a sticky secretion. ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

Olearia Tasmanica
''Olearia tasmainca'' is a species of flowering plant in the family Asteraceae and is endemic to Tasmania. It is a shrub that typically grows to a height of and has oblong to egg-shaped leaves with the narrower end towards the base, long and with a blunt tip. The heads or daisy-like "flowers" have up to 8 ray florets. Flowering mainly occurs in January and the fruit is a smooth achene. This daisy was first formally described in 1847 by Joseph Dalton Hooker who gave it the name ''Eurybia alpina'' in the ''London Journal of Botany'' from specimens collected on Mount Wellington. In 1963, Winifred Curtis changed the name to ''Olearia alpina'' in ''The Student's Flora of Tasmania'', but that name is illegitimate because it had already been used by Buchanan for a New Zealand species (now known as '' Olearia lacunosa''). In 1970, Curtis changed the name to ''Olearia tasmanica'' in ''The Victorian Naturalist ''The Victorian Naturalist'' is a bimonthly scientific journal covering ...

Tasman Peninsula
The Tasman Peninsula, officially Turrakana / Tasman Peninsula, is a peninsula located in south-east Tasmania, Australia, approximately by the Arthur Highway, south-east of Hobart.

Flora Australiensis
''Flora Australiensis: a description of the plants of the Australian Territory'', more commonly referred to as ''Flora Australiensis'', and also known by its standard abbreviation ''Fl. Austral.'', is a seven-volume Flora of Australia published between 1863 and 1878 by George Bentham, with the assistance of Ferdinand von Mueller.

George Bentham
George Bentham (22 September 1800 – 10 September 1884) was an English botanist, described by the weed botanist Duane Isely as "the premier systematic botanist of the nineteenth century". Born into a distinguished family, he initially studied law, but had a fascination with botany from an early age, which he soon pursued, becoming president of the Linnaean Society in 1861, and a fellow of the Royal Society in 1862. He was the author of a number of important botanical works, particularly flora. He is best known for his taxonomic classification of plants in collaboration with Joseph Dalton Hooker, his ''Genera Plantarum'' (1862–1883). He died in London in 1884. Life Bentham was born in Stoke, Plymouth, on 22 September 1800. His father, Sir Samuel Bentham, a naval architect, was the only brother of Jeremy Bentham to survive into adulthood. His mother, Mary Sophia Bentham, was a botanist and author. Bentham had no formal education but had a remarkable linguistic aptitude. By ...
