An essay on Australia's unique flora and fauna

The long geographic isolation of Australia fromother continents has resulted in an exceptionalvariety of engraft and fleshly life. From arid pennyralAustralia to the tropical tones of northQueens agriculture, 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 funding in Australia Ð about one millionÐ is more than doubly the total of species inNorth America and Europe combined. Due to the generally misfortunate amounts of rain andits unreliability, closely 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 exit of course in Australia andnowhere else in the world. For example, virtually ofAustralias calciferol different species of Eucalyptus(gum trees) be endemic. Some plant species atomic number 18not solitary(prenominal) unequalled to Australia but also unequaled tosmall areas of Australia. For example, about 75per cent of the blossoming trees and shrubs in thesouth-west corner of Australia have been lay down tobe eccentric to this area. pile trees (Xanthorrhea sp.) are among the many plantspecies that are endemic Ð they occur naturally still inAustralia. UNIQUE FLORAThe distribution of vegetation in Australia isstrongly influenced by temper. Only about five percent of Australia is forested. most of this forest vegetationoccurs along the wetter eastern coast andhighlands area. The forests are dominate by eucalypttrees, which are tough and dur adapted 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 in that location. Furtherinland, as the climate becomes increasingly dry,grasslands and shrubs begi n to dominate. most of the worlds marsupials! are found inAustralia. They take the bandicoot, koala,kangaroo, wallaby, wombat and the Tasmaniandevil. pouched mammals have pouches in which theysuckle and carry their young. Marsupial babiesare born in a tiny immature produce 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 convey that theyoung remain in the womb for much longer thanmarsupials and thither is no pouch.

Australian placentalanimals include bats and rodents and suchmarine mammals as seals, dugongs and dolphins. Most mamm als reproduce 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 echidna. One echidna 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/ 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, coiffe it on our website: OrderCustomPaper.c! om
