An essay on Australia's unique flora and fauna

The long geographic isolation of Australia fromother continents has resulted in an exceptionalvariety of deeds and sensual life. From arid centimeralAustralia to the tropical tones of northQueens earth, no other country has such(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 life in Australia Ð about one millionÐ is more than in two ways the total of species inNorth America and Europe combined. Due to the generally woeful 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 do of course in Australia andnowhere else in the world. For example, about ofAustralias calciferol different species of Eucalyptus(gum trees) ar endemic. Some plant species atomic number 18not except unequalled to Australia but also preposterous tosmall areas of Australia. For example, about 75per cent of the blossoming trees and shrubs in thesouth-west corner of Australia have been found tobe fantastic to this area. pile trees (Xanthorrhea sp.) are among the many plantspecies that are endemic Ð they occur naturally tho inAustralia. UNIQUE FLORAThe distribution of vegetation in Australia isstrongly influenced by temper. Only about five percent of Australia is forested. around of this forest vegetationoccurs along the wetter eastern coast andhighlands area. The forests are dominate by eucalypttrees, which are tough and durcapable 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 there. Furtherinland, as the climate becomes increasingly dry,grasslands and shrubs begin to dominate. to the highest degree of the worlds marsupials are found inAustralia! . 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 reconcile 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 center 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 bi rth 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 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/ 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, severalise it on our website: OrderCustomPaper.com
