An essay on Australia's unique flora and fauna

The long geographic isolation of Australia fromother continents has resulted in an exceptionalvariety of gear up and animal(prenominal) life. From arid centralAustralia to the tropical tones of northQueens convey, 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 victuals in Australia Ð about one millionÐ is more than twice the total of species inNorth America and Europe combined. Due to the generally dis dictateed amounts of rain andits unreliability, near 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 exceed of course in Australia andnowhere else in the world. For example, about ofAustralias calciferol different species of Eucalyptus(gum trees) atomic number 18 endemic. Some plant species argonnot and unequalled to Australia but also alone(p) 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 odd to this area. pile trees (Xanthorrhea sp.) are among the many plantspecies that are endemic Ð they occur naturally moreover inAustralia. UNIQUE FLORAThe distribution of vegetation in Australia isstrongly influenced by temper. Only about five percent of Australia is forested. just about of this forest vegetationoccurs along the wetter eastern coast andhighlands area. The forests are dominate by eucalypttrees, which are tough and dur up to(p) 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 respect. Furtherinland, as the climate becomes increasingly dry,grasslands and shrubs begin to dominate. nigh of the worlds marsupials are found in! Australia. 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 acres 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 elbow room that theyoung remain in the womb for much longer thanmarsupials and at that place 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 scaly anteater. One aardvark speciesoccurs in naked Guinea but the platypus and theother species of echidna are unequivocally Australian. Loss of species in Australia has been 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/depository 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, order it on our website: OrderCustomPaper! .com
