For many years Australia has been an isolated land, away in the bottom corner of the world, surrounded by thousands of kilometres of ocean at some points. This isolation has developed entire unique ecosystems across Australia, ones that are full of unique native animals and plants. On the 26th January 1788, the First Fleet reached Sydney Cove, this event would change the fate of Australia forever. The British did not only introduce themselves and convicts into the new southern land, they also introduced many new animal and plant species into Australia and these new species all affected the ecosystems and animals that are native to Australia. The First Fleet directly brought a few species with them when they arrived in 1788; rabbits, goats, sheep, cows, horses, hogs and chickens were all aboard the First Fleet headed to Australia. The First Fleet also took two types of plant with them; the Spanish Reed and the Prickly Pear. These biotic factors all eventually had an impact on Australia. …show more content…
One animal that has had a significant impact on Australia is the cane toad. The cane toad was introduced in 1935 by the Bureau of Sugar Experiment Stations to try and control the population of the native cane beetle and Frenchi beetle, these species of beetle were the biggest problem that the sugar cane farms faced as the larvae of these beetles fed on the roots of the sugar cane plants. So, against the advice of scientist, the Bureau released around 100 cane toads into wild around certain areas of Queensland. As seen in fig. 2, the cane toads spread quickly and directly had a large effect on the environment and, worst of all, there is no evidence that the cane toads affected the population of beetles in those
They ate different foods, and had a different religion. When the English came, they brought conflicts, along with people with different cultures that changed Australia’s from the it was, to the way it to today.
It is well known that Captain Arthur Philips landed in Australia on 26th of January and took over the land and is referred to as “invasion Day”. Yet little do people know, Captain Arthur Phillip didn’t land in Australia on 26 January. He first landed in Australia between the 18th and 20th of January 1788 in Botany Bay, however where he landed he couldn’t find fresh water so he then sailed into Sydney Cove on the 26th where he found a Tank Stream…..problem solved. Australia day today celebrates our diverse society, our remarkable achievements, our future as a nation and how we can make Australia a better
Why Australia? What is Australia anyway1? The continent itself is clear enough, burned into my mind on long hot afternoons in the Third Grade when I learned to sketch in its irregular coastline: the half-circle of the Great Australian Bight, the little booted foot of Eyre's Peninsula. Spencer's Gulf down to Port Philip … … I know the outline; I know the names (learned painfully for homework) of several
A species in particular that I have researched is the red fox or Vulpes vulpes as it is known in the scientific community. The animal is native to North America, Asia and Europe where they thrive in habitats ranging from temperate deserts to boreal forests, but its range spans the entire globe (Tesky 1995). The red fox is omnivorous which means that it feeds on animals and plants equally, which, creates impacts on both types of populations within its habitat. What makes the red fox invasive is its introduction to Australia and Eastern parts of the United States, as a result of migration of Europeans t...
Brumbies are known as the feral horses that inhabit Australia- mostly throughout the Northern Territory, Queensland and scattered centrally in Western Australia. Some small mobs live within Victoria and New South Wales, but none as vast or dense in population. These horses influence the natural habitat in many ways- they reduce vegetation growth, cause soil erosion and impact upon other animals living within the ecosystem. They are seen as pests to national parks, and essentially, this is the reason for their culling- they cause more damage than they are worth. The only positive aspect a brumby herd will impose is that they maintain walking and driving tracks throughout state parks.
Before taking a look into the effects the European animals had on the environment, we must first view the way things were prior to their introduction. During the time which pre-dated the arrival of the Europeans, the Americas were basically untouched. The land was populated with not just Indians, but also vast numbers of plants and animals. The land provided almost all of the needs of the Indians and in return, the Indians took care of the land.
There are an estimated, tens of thousands pythons living in the Everglades. One Burmese python can eat a lot by itself, but then you multiply that by tens of thousands, mass amounts of animal life goes down. The newspaper said,”With no natural predators, these eating machines appear to be wiping out huge numbers of opossums, raccoons, and bobcats, as well as many bird species.” This shows that the tens of thousands of Burmese pythons living in the Everglades are having a mass effect on the animal species living in the Everglades. If the Burmese pythons problem does not go away, it may lead to the extinction of some types of animals in the
On the 29th o April, 1977 Captain Cook, commander of a British fleet, landed on the eastern shore of Australia, in an attempt to claim the land under the name of Britain. The land was to be claimed by Britain as a land where the British government could send convicts; in an attempt to ease the struggle in the over flowing prisons. Upon Cooks arrival, he was ordered to follow three rules of claiming a foreign land. They were;
Since then, cane toads have been moving through Australia Northern scene and are moving westbound at 40 to 60 km each year. Cane toads populated Brisbane by 1945, Burketown by the mid-1980s, cane toad amphibians were acquainted in Byron Bay in 1965 and spread to shorelines of NSW in 2003. Cane toads colonise areas of human habitation and cause major impacts on health concerns to people, the risk of children or pets being poison from contact with the toads is a major concern. For Aboriginal people traditional food sources, the devastating impact on the native predator species such as goannas is also a concern, cane toads produce large numbers of offspring causing major concerns to the rapid increase rate of cane toads, research from the University of Sydney shows that cane toads are evolving adaptations to suit their new biodiversity, allowing toads to move at a rapid
Leaders of Australia have impacted the country and how it has developed, in many ways. One example of these important leaders is Captain James Hook. In 1770 a British sailor, Captain James Hook explored the east coast and claimed it as Russia’s. When he arrived a new outpost was put as a penal colony. 8 years later on January 26 1778 the First Fleet arrived. 11 ships carried 1,500 people, half of them convicts. When the penal transportation took a stop in 1868 more than 160,000 men and women came to Australia as convicts. In 1868 the convicts did not have it easy. Men could be hanged for the littlest things like stealing. January 26, a day in the Australian world where they celebrate the end of the first fleet.

The arrival of the Boat People of Vietnam played a huge part in Australian history. This was the turning point from when the Australians believed in the phrase Populate or Perish and only wanted to bring in English immigrants, to welcoming and helping the Vietnamese. They would stop the people of other nationalities by making near impossible literacy tests in the language that that person was least likely to know. This made sure that Australia was almost a completely white nation. When the Australian government started to realize the struggles of the Vietnamese, the lengths
All discussions regarding the phenomenon of invasive species will inherently result in the consensus that they are an unwanted or an even evil entity. Ever since the age of exploration humans have been primary dispersers of these so called “exotic” species (Mooney and Cleland 2001). Famous examples include the release of cane toads in Australia (Urban et al., 2008); the rainbow trout (Fausch 2008) and the Japanese Kudzu vine in the southern U.S. (Blaustein 2001) and zebra mussels in the great lakes of Canada (Nalepa and Schloesser 1992). However, documented marine invasions compared with

The Australia Outback is portrayed in films as vast and red. Of Course Australia is not completely this description. In the film, Crocodile Dundee, Sue Charlton (heroine character) is a New York journalist visiting Sydney. The Irony is the complete contrast between the desert landscape, shown as a bird’s eye view in the helicopter (Scene 2 Crocodile Dundee). In Priscilla, Queen of the Desert the imagery of a “never-ending” road reaffirms the idea that Australia is an isolated place. Similarly to Crocodile Dundee, Priscilla, Queen of the Desert exposition began in Sydney. The main difference between the films the ‘outback’ where both film plo...
