A successful introduced species eradication scheme is one that, once the intro. species has "done it's job" then it dies because there is no more pest/ feral organisms for it to survive on. However, some schemes are unsuccessful and the introduced species becomes a pest, a good example of this in Australia is the well known cane toad, some of the effects this organism has had on the Australian environment is that, because the toads are in fact poisonous, because of their warts, their poison has killed alot of Australia's natural, carnivorous, species, such as the chuditch, and also household pets. The toad also takes over some environments and drives out other species that live there.
Another is the magnificent brumbies, they were once farm horses for the migrants from England, but broke free and became "feral" (once domesticated) these horses also drive out other organisms not on purpose, but because of natural competition for food. They are also the main culprit for soil erosion on the hills due to their galloping along in big herds, this obviously will have a huge impact on the "compactiveness" of the soil.

No. the prickly pear is not native to Australia. It is an introduced species, and a noxious pest.
no. the fox is an introduced species, brought to Australia for the sport of foxhunting.
Yes, knotweed is an entirely introduced species.
it has been moved to a new area.
Yes. Both the rabbit and the fox have been introduced to Australia, and both have caused massive damage since their arrival.
When species are introduced to new locations where they are not native, they are termed as "introduced species" or "invasive species." These introductions can disrupt ecosystems, outcompete native species, and impact local biodiversity. Examples include the cane toad in Australia and the zebra mussel in North America.
Preying upon native species competing with native species for resources displacing native species :)
Yes. There are many species of pigeons in Australia, both native and introduced. There are, in fact, about 22 species of native pigeon in Australia.Native pigeons in Australia include:Common bronzewing pigeonBrush bronzewingWonga PigeonCrested pigeonTopknot pigeonWhite-headed pigeonSpinifex pigeonSquatter pigeon
