Tuart Forest
Tuart forest is an open forest in which the dominant overstorey tree is '' Eucalyptus gomphocephala'' (tuart). This form of vegetation occurs only in the Southwest Botanical Province of Western Australia. Tuart being predominantly a coastal tree, tuart forest occurs only in a narrow belt along the coast. Logging history and conservation Coastal land in the southwest of Western Australia has been in high demand ever since British settlement of the Swan River Colony, initially for grazing, and more recently for housing. Tuart was also a prized timber. It is light in colour, similar to honey oak, and unusually hard. It was particularly useful where a very hard wood was needed, and most old-style butchers had a tuart "round" as a durable chopping block. As a result of its value as a timber and as grazing land, most of the tuart forest has now been cleared. The only remaining tall tuart forest is the Ludlow Tuart Forest now protected by the Tuart Forest National Park. Other tuart fore ...

Ludlow Forest Gnangarra 02
Ludlow () is a market town in Shropshire, England. The town is significant in the history of the Welsh Marches and in relation to Wales. It is located south of Shrewsbury and north of Hereford, on the A49 road which bypasses the town. The town is near the confluence of the rivers Corve and Teme. The oldest part is the medieval walled town, founded in the late 11th century after the Norman conquest of England. It is centred on a small hill which lies on the eastern bank of a bend of the River Teme. Situated on this hill are Ludlow Castle and the parish church, St Laurence's, the largest in the county. From there the streets slope downward to the rivers Corve and Teme, to the north and south respectively. The town is in a sheltered spot beneath Mortimer Forest and the Clee Hills, which are clearly visible from the town. Ludlow has nearly 500 listed buildings, including examples of medieval and Tudor-style half-timbered buildings. The town was described by Sir John Betje ...

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 ca ...

Eucalyptus
''Eucalyptus'' () is a genus of over seven hundred species of Flowering plant, flowering trees, shrubs or Mallee (habit), mallees in the Myrtaceae, myrtle Family (biology), family, Myrtaceae. Along with several other genera in the Tribe (biology), tribe Eucalypteae, including ''Corymbia'', they are commonly known as eucalypts. Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard or stringy, leaves with oil Gland (botany), glands, and sepals and petals that are fused to form a "cap" or Operculum (botany), operculum over the stamens. 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. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which sur ...

Natural History Of Western Australia
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

Vegetation Of Australia
Vegetation is an assemblage of plant species and the ground cover they provide. It is a general term, without specific reference to particular taxa, life forms, structure, spatial extent, or any other specific botanical or geographic characteristics. It is broader than the term ''flora'' which refers to species composition. Perhaps the closest synonym is plant community, but ''vegetation'' can, and often does, refer to a wider range of spatial scales than that term does, including scales as large as the global. Primeval redwood forests, coastal mangrove stands, sphagnum bogs, desert soil crusts, roadside weed patches, wheat fields, cultivated gardens and lawns; all are encompassed by the term ''vegetation''. The vegetation type is defined by characteristic dominant species, or a common aspect of the assemblage, such as an elevation range or environmental commonality. The contemporary use of ''vegetation'' approximates that of ecologist Frederic Clements' term earth cove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Shelduck
The Australian shelduck (''Tadorna tadornoides''), also known as the chestnut-breasted shelduck or mountain duck, is a shelduck, a group of large goose-like ducks part of the bird family Anatidae. The genus name ''Tadorna'' comes from Celtic roots and means "pied waterfowl". They have a striking chestnut-coloured breast and black body. They are protected under the National Parks and Wildlife Act 1974. Taxonomy and naming William Jardine and Prideaux John Selby described the Australian shelduck in 1828. Description The males are mostly dark, with a chestnut breast. They have white neck collars and dark green heads. The females are similar, but they have white around the eyes and are smaller. Both males and females have chestnut and black wings with a green speculum, and show some white on their wings during flight. The downy young are white with a brown crown and brown stripes from crown to tail. Juvenile males are duller than the adults and also lack a white collar, while juv ...

Whistling Kite
The whistling kite (''Haliastur sphenurus'') is a medium-sized diurnal raptor found throughout Australia (including coastal islands), New Caledonia and much of New Guinea (excluding the central mountains and the northwest). Also called the whistling eagle or whistling hawk, it is named for its loud whistling call, which it often gives in flight. Some authorities put this species in the genus '' Milvus'', despite marked differences in behaviour, voice and plumage between this species and other members of that genus. Description The whistling kite ranges in size from , with a wingspan between . Weights range from an average of for males and for females. As with most raptors, females are larger and heavier than males; though there is considerable overlap between the sexes, females can be up to 21% larger and 42% heavier. Southern birds are also larger than those found in the tropics. Male and female plumages are the same. Adult birds are a pale buff on the head ...

Osprey
The osprey (''Pandion haliaetus''), , also called sea hawk, river hawk, and fish hawk, is a diurnal, fish-eating bird of prey with a cosmopolitan range. It is a large raptor reaching more than in length and across the wings. It is brown on the upperparts and predominantly greyish on the head and underparts. The osprey tolerates a wide variety of habitats, nesting in any location near a body of water providing an adequate food supply. It is found on all continents except Antarctica, although in South America it occurs only as a non-breeding migrant. As its other common names suggest, the osprey's diet consists almost exclusively of fish. It possesses specialised physical characteristics and exhibits unique behaviour to assist in hunting and catching prey. As a result of these unique characteristics, it has been given its own taxonomic genus, ''Pandion'', and family, Pandionidae. Taxonomy The osprey was described by Carl Linnaeus under the name ''Falco haliaeetus'' in his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vasse-Wonnerup Estuary
The Vasse-Wonnerup Estuary is an estuary in the South West (Western Australia), South West region of Western Australia close to the town of Busselton, Western Australia, Busselton. The estuary is listed with A Directory of Important Wetlands in Australia, DIWA. It was also recognised as a wetland of international importance under the Ramsar Convention on 7 June 1990 when an area of was designated Ramsar Site 484 as an important dry-season habitat for waterbirds. It is also the main part of the Busselton Wetlands Important Bird Area. Description The estuary is wave dominated and has been severely modified from its natural state. The site of the Vasse and Wonnerup Floodgates that regulated the flow of water in the estuary from about 1907 inadvertently created the freshwater wetland, were listed on the Western Australian Register of Heritage Places in 2005. The estuary covers a total surface area of with the central basin having an area of In winter, wide areas of open water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tadarida Australis
The white-striped free-tailed bat (''Austronomus australis'') is a species of bat in the family Molossidae. Its echolocation calls are audible to humans, which is a characteristic found in only a few microbat species. The species was formerly classified as ''Tadarida australis''. Taxonomy The first description of the species was published in 1838 by John Edward Gray, in a review of material at the British Museum of Natural History. The author noted the source of the specimen, a skin and skull, as New South Wales and placed it with the genus '' Molossus''. When providing a description in ''Furred Animals of Australia'', Ellis Troughton suggested that the specimen examined by Gray was obtained at Camden, a property owned by John Macarthur. Troughton first proposed the species be distinguished as a monotypic genus ''Austronomus'', this arrangement was eventually resurrected when the taxon was separated from the previously accepted alliance with the widespread genus ''Tadarida' ...

Isoodon Obesulus
The southern brown bandicoot (''Isoodon obesulus'') is a short-nosed bandicoot, a type of marsupial, found mostly in southern Australia. It is also known as the quenda in South Western Australia (from the Noongar word ''). Taxonomy George Shaw described the species as ''Didelphis obesula'' in 1797. While some authorities list as few as two subspecies (''I. o. obesulus'' and ''I. o. nauticus''), there are currently five recognised species: * ''Isoodon obesulus nauticus'' - restricted to the Nuyts Archipelago * ''Isoodon obesulus obesulus'' - NSW, Victoria, SA * ''Isoodon obesulus peninsulae'' - Cape York Peninsula * ''Isoodon obesulus affinus'' - Tasmania and Bass Strait Islands * ''Isoodon obesulus fusciventer'' - southwest WA Description Southern brown bandicoots have a stocky body with a short snout and short, rounded ears. They show sexual dimorphism, with females being smaller than males. On average, males measure in total length, and weigh up to , while females measure ...

Phascogale Tapoatafa
The brush-tailed phascogale (''Phascogale tapoatafa''), also known by its Australian native name tuan, the common wambenger, the black-tailed mousesack or the black-tailed phascogale, is a rat-sized arboreal carnivorous marsupial of the family Dasyuridae, characterized by a tuft of black silky hairs on the terminal portion of its tail. Males of this species do not live past the age of one, as they die after reproducing. Taxonomy The brush-tailed phascogale was first described by Friedrich Meyer in 1793; George Shaw published a revised description in 1800. For some time it was considered a member of the opossum genus ''Didelphis'', but this ended in 1844 when Coenraad Jacob Temminck erected the genus ''Phascogale''. The species is closely related to the red-tailed phascogale (''P. calura''). Its scientific name, ''tapoatafa'', is a reference to an indigenous Australian name for the species. It has sometimes been known as ''Phascogale penicillata'', referring to its brushed tail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
