Western Ground Parrot
The western ground parrot (''Pezoporus flaviventris''; Noongar name ''kyloring'') is an endangered species of parrot endemic to Western Australia and is a close relative of the eastern ground parrot (''Pezoporus wallicus'') and the somewhat more distantly related and mysterious night parrot (''Pezoporus occidentalis''). It is one of the world's rarest birds with about 150 individuals remaining . The western ground parrot plumage is similar to the eastern ground parrot, but feathers of the abdomen and under tail-coverts are bright yellow with indistinct black barring. Molecular DNA evidence suggests the western ground parrot split from ground parrots of eastern Australia around 2 million years ago. Taxonomy Described as a separate species by Alfred John North in 1911, on account of its distinctive plumage. North compared Western Australian specimens, at the Australian Museum, collected by George Masters in the 1860s at a location noted as King George Sound. The specific name ...

Alfred John North
Alfred John North (11 June 1855 – 6 May 1917) was an Australian ornithologist. North was born in Melbourne and was educated at Melbourne Grammar School. He was appointed to the Australian Museum, Sydney in 1886 and was given a permanent position there five years later. He wrote a ''List of the Insectivorous Birds of New South Wales'' (1897) and a ''Descriptive Catalogue of the Nests and Eggs of Birds Found Breeding in Australia and Tasmania'' (1889) with George Barnard as co-author. He described a number of birds for the first time, many in the ''Victorian Naturalist'', the magazine of the Field Naturalists Club of Victoria of which he was a founding member.

Esperance, Western Australia
Esperance is a town in the Goldfields–Esperance region of Western Australia, on the Southern Ocean coastline approximately east-southeast of the state capital, Perth. The urban population of Esperance was 12,145 at June 2018. Its major industries are tourism, agriculture, and fishing. History European history of the region dates back to 1627 when the Dutch vessel ''Gulden Zeepaert'', skippered by François Thijssen, passed through waters off the Esperance coast and continued across the Great Australian Bight. French explorers are credited with making the first landfall near the present day town, naming it and other local landmarks while sheltering from a storm in this area in 1792. The town itself was named after a French ship, the ''Espérance'', commanded by Jean-Michel Huon de Kermadec. fr , Espérance , label=none is French for "hope". In 1802, British navigator Matthew Flinders sailed the Bay of Isles, discovering and naming places such as Lucky Bay and Thistle Co ...

Phytophthora Cinnamomi
''Phytophthora cinnamomi'' is a soil-borne water mould that produces an infection which causes a condition in plants variously called " root rot", "dieback", or (in certain ''Castanea'' species), "ink disease". The plant pathogen is one of the world's most invasive species and is present in over 70 countries around the world. Host range and symptoms The host range for ''Phytophythora cinnamomi'' is very broad. It is distributed worldwide and causes disease on hundreds of hosts. The disease affects a range of economic groups, including food crops such as avocado and pineapple as well as trees and woody ornamentals such as Fraser firs, shortleaf pines, loblolly pines, azaleas, camellia, boxwood, causing root rot and dieback. It is a root pathogen that causes root rot and death of host plants. Some symptoms include: wilting, decreased fruit size, decrease in yield, collar rot, gum exudation, necrosis, leaf chlorosis, leaf curl, and stem cankers. Another symptom is that it can ...

Bushfire
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable fire in an area of Combustibility and flammability, combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire(bushfires in Australia, in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Fire ecology, Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burn, controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurre ...

Feral Cats In Australia
Cats are an invasive species in Australia. Because they are not native to Australia and were only introduced by colonisers as pets in the early 1800s, native Australian animals did not co-evolve with them. , some 3.8 million domestic cats and up to 6.3 million feral cats continue to live in Australia. Every year domestic and feral cats in Australia kill 1,067,000,000 mammals, 399,000,000 birds, 609,000,000 reptiles, and 92,000,000 frogs. As one of the most ecologically damaging and the most costly invasive species in Australia, predation by both domestic and feral cats has played a role in the extinction of many of Australia's Indigenous animals. For instance, cats are found to have significantly contributed to the extinction of at least 22 endemic Australian mammals since the arrival of Europeans. For biosecurity reasons, any cats that are imported into Australia must meet conditions set by the Department of Agriculture, Fisheries and Forestry. Historical context Historica ...

Red Foxes In Australia
Red foxes pose a serious conservation problem in Australia. 2012 estimates indicate that there are more than 7.2 million red foxes (''Vulpes vulpes'') and growing with a range extending throughout most of the continental mainland. The species became established in Australia through successive introductions by settlers in 1830s. Due to its rapid spread and ecological impact it has classified as one of the most damaging invasive species in Australia. Introduction and spread Red foxes were introduced to the British colonies of Van Diemen's Land (as early as 1833) and the Port Phillip District and Sydney Regions of New South Wales (as early as 1845) for the purpose of the traditional English sport of fox hunting. Curiously a permanent fox population was not established on the island of Tasmania and it is widely held that they were outcompeted by the Tasmanian devil. On the mainland, however, the species was successful as an apex predator. The spread of red foxes across the south ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin ('' Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range ...

Cyperaceae
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus '' Carex'' with over 2,000 species. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands or sedge meadows. Some species superficially resemble the closely related rushes and the more distantly related grasses. Features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections (with occasional exceptions, a notable example being the tule which has a round cross-section) and leaves that are spirally arranged in three ranks. In comparison, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Arid National Park
Cape Arid National Park is a national park located in Western Australia, southeast of Perth. The park is situated east of Esperance and lies on the shore of the south coast from the eastern end of the Recherche Archipelago. The bay at its eastern side is Israelite Bay, a locality often mentioned in Bureau of Meteorology weather reports as a geographical marker. The western end is known as Duke of Orleans Bay. Its coastline is defined by Cape Arid, a bay called Sandy Bight and, further east, Cape Pasley. History The first European to discover the area was the French Admiral Bruni D'Entrecasteaux in 1792 and he named it ''Cap Aride''; Matthew Flinders anglicized the name in 1802 and the park took its name from this feature. Pioneer graziers arrived in the area in the 1870s and the ruins of homesteads, dams and buildings as well as gravesites can be found near Pine Hill and Thomas Fishery. Bay whaling was conducted by Thomas Sherratt at Barrier Anchorage in the 1870s. John Tho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albany, Western Australia
Albany ( ; nys, Kinjarling) is a port city in the Great Southern region in the Australian state of Western Australia, southeast of Perth, the state capital. The city centre is at the northern edge of Princess Royal Harbour, which is a part of King George Sound. The central business district is bounded by Mount Clarence to the east and Mount Melville to the west. The city is in the local government area of the City of Albany. While it is the oldest colonial, although not European, settlement in Western Australia - predating Perth and Fremantle by over two years - it was a semi-exclave of New South Wales for over four years until it was made part of the Swan River Colony. The settlement was founded on 26 December 1826 as a military outpost of New South Wales for the purpose of forestalling French ambitions in the region. To that end, on 21 January 1827, the commander of the outpost, Major Edmund Lockyer, formally took possession for the British Crown of the portion o ...
