An essay on Australia's unique flora and fauna

The long geographic isolation of Australia fromother continents has resulted in an exceptionalvariety of whole kit and carnal life. From arid centralAustralia to the tropical tones of northQueens basis, no other country has much(prenominal) a variety. More than 80 per cent of Australias industrial plant andfauna is be nowhere else in the world. Theestimated enumerate of native and introducedspecies subsisting in Australia Ð about one millionÐ is more than doubly the total of species inNorth America and Europe combined. Due to the generally pathetic amounts of rain andits unreliability, roughly of the flora in Australia ischaracterised by drought-resistant qualities. TheAustralian land flora comprise over 12 000 speciesand many of these ar endemical to Australia Ðthat is, they arrive of course in Australia andnowhere else in the world. For example, roughly ofAustralias calciferol different species of Eucalyptus(gum trees) be endemic. Some plant species aren ot exclusively unequalled to Australia but also extraordinary tosmall areas of Australia. For example, about 75per cent of the blossoming trees and shrubs in thesouth-west corner of Australia have been frame tobe funny to this area. pile trees (Xanthorrhea sp.) are among the many plantspecies that are endemic Ð they occur naturally provided inAustralia. UNIQUE FLORAThe distribution of vegetation in Australia isstrongly influenced by temper. Only about five percent of Australia is forested. almost of this forest vegetationoccurs along the wetter eastern coast andhighlands area. The forests are dominate by eucalypttrees, which are tough and dur satisfactory and able towithstand the give away ongoing winds that occur. As rainfalldecreases inland, trees decrease in number andbecome littler and further apart. Eucalypts arestill the main types of tree found at that place. Furtherinland, as the climate becomes increasingly dry,grasslands and shrubs begin to dominate. intimat ely of the worlds marsupials are found inAus! tralia. They take the bandicoot, koala,kangaroo, wallaby, wombat and the Tasmaniandevil. marsupials have pouches in which theysuckle and carry their young. Marsupial babiesare born in a tiny immature tell apart and completemuch of their development in the pouch. Despite the number of unique marsupials inAustralia, most of our native animals are not marsupials. Most are placentals, which mover that theyoung remain in the womb for much longer thanmarsupials and in that location is no pouch.

Australian placentalanimals include bats and rodents and suchmarine mammals as seals, dugongs and dolphins. Most mammals repr oduce by giving birth to liveyoung. Monotremes are unique in creation the onlymammals that lay eggs. There are only threespecies of monotreme in the world: the platypusand two species of aardvark. One anteater speciesoccurs in naked Guinea but the platypus and theother species of echidna are unequivocally Australian. Loss of species in Australia has been largelycaused by home ground destruction and degradationand this caper is still occurring. Because mostAustralian species are found nowhere else, wehave a exceptional responsibility to conserve them. There are the same number of species ofreptiles in an average Australian backyardas there are in the whole of England. http://www.terrace.qld.edu.au/ program library/grade7/naturalresources.htmlhttp://www.australia-migration.com/page/Soils_Fauna_and_Flora/230http://www.totaltravel.com.au/library/traveler/australian-flora-fauna If you want to get a full essay, suppose it on our website: < a href='http://ordercustompaper.com/'>OrderCustomPape! r.com
