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 boodle and sensual life. From arid pennyralAustralia to the tropical tones of northQueens let down, 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 animation in Australia Ð about one millionÐ is more than doubly the total of species inNorth America and Europe combined. Due to the generally small-scale amounts of rain andits unreliability, close 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 issue forth of course in Australia andnowhere else in the world. For example, most ofAustralias calciferol different species of Eucalyptus(gum trees) argon endemic. Some pl ant species arenot notwithstanding unequalled to Australia but also quaint tosmall areas of Australia. For example, about 75per cent of the blossoming trees and shrubs in thesouth-west corner of Australia have been plunge tobe crotchety to this area. pile trees (Xanthorrhea sp.) are among the many plantspecies that are endemic Ð they occur naturally scarce inAustralia. UNIQUE FLORAThe distribution of vegetation in Australia isstrongly influenced by temper. Only about five percent of Australia is forested. well-nigh of this forest vegetationoccurs along the wetter eastern coast andhighlands area. The forests are dominate by eucalypttrees, which are tough and dur competent 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 on that point. Furtherinland, as the climate becomes increasingly dry,grasslands and shrubs begin to d ominate. nearly of the worlds marsupials ar! e 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 separate 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 government agency that theyoung remain in the womb for much longer thanmarsupials and there is no pouch. Australian placentalanimals include bats and rodents and suchmarine mammals as seals, dugongs and dolphins. Most mammals 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 anteater. One numbat speciesoccurs in naked Guinea but the platypus and theother species of echidna are unequivocally Australian. Loss of species in Australia has bee n largelycaused by habitat 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, format it on our website: OrderCustomPaper.com
