Invasive species on Rottnest island?

What effects have introduced species had on the natural species present on Rottnest island?

  • Answer:

    the effect of introduced species has a devastating impact on the native species, they out compete the natives for food & resources or they prey on them. rats for instance eat bird eggs, cats, dogs kill native animals. They bring disease with them, natives may have no natural resistance to & so wipe them out. the ecology of the island ( and I don't know where this is ) will alter, introduced plants may be hardier and change the landscape, or they may be inedible.
