The European Rabbit is another invasive species that plagues Australia Finally, high genetic variability is a key to any successful invasion, the more organisms that are introduced as an invasive species, the more likely they are to succeed and persist. Generalists, those species with permissive diets and a wide range of suitable habitats are often successful invaders due to their adaptability. Species with high dispersal rates intrinsically make good invaders because of their ability to rapidly colonize an entire environment from a limited point of introduction. Pioneer species, those that are well suited to colonizing new and disrupted habitats, are often successful as invaders due to their inherent predisposition for success in contested habitats.
At the same time, organisms with long life spans also make for good invaders, as even a few organisms are able to persist in a new environment for considerable periods of time.
Species that are considered r-selected species, those with high fecundity and a low generation time, often make good invaders as they can quickly populate an invaded environment. The infamous cane toad presents a severe problem in Australia
