Australia Invasive Species Essay
Species had introduced to Australia by human since 1788. When a foreign species had successfully out-compete native organisms for food and habitat, it may survive and reproduce. However this species can become invasive when there is an excessive increase of population which can cause enormous damage to the ecosystem. The impacts of the foreign species could be immense, insidious and irreversible.
In Australia, invasive species have been recognized one of the most serious threats to biodiversity. According to Environment Protection and Biodiversity Conservation Act 1999 (EPBC), invasive species are the primary cause of animal extinctions in Australia. Invasive species cause about three-quarters of the vertebrate animals and one-third of the …show more content…
Red foxes don’t have much natural predators in Australia, most death only occur due to human activities or drought. In addition, red fox is a predator of variety species. They played a decisive role in the decline and extinctions of small and medium sized species. A brief review by the department of the Environment, Water, Heritage and the Arts (DEWHA) (2008) identified that red fox are considered a treat to 48 mammals, 14 birds, 12 reptiles and 2 amphibians. Furthermore, as they also consume a range of fruits and carrions. These allow them to out-compete Australia’s native organisms for food. Now red fox had spread across Australia and the presently inhabit is about 76% of the continent (West, 2008, p. …show more content…
Due to the temperature increase, species have to migrate to higher elevations or latitudes to areas with preferred climate. However migration might not be possible for some species, due to the geographical, human actives or exist of competition species. Furthermore, climate change might benefit to some introduced species, such as dingo. Dingo is classified as the Australia’s largest land predator. Sciences predict that the distribution and abundance of dingo will increase because of the climate change. This expand their prey base and will be implications for either native or invasive
