You might have heard of some of Australia’s native species, like the kangaroo or the koala. They are just two of thousands of native species. But is every plant or animal native to Australia? No, animals like cats and dogs are not native to Australia, these species that dominate over native species are called invasive species. Over twenty million native animals are killed by invasive species every day. Invasive Species aren’t just animals they can be plants as well, in fact there are way more invasive plants than animals.
