Invasive species of Australian origin such as the kereru, tui, and kaka. They are a carrier of tuberculosis which they spread to pasture and hence livestock. Control of them has been an ongoing project of regional councils, the Department of Conservation, Forest and Bird, and various other wildlife preservation organizations. Perhaps the best known example of an Australian plant becoming an invasive species is the problematic introduction of "Melaleuca quinquenervia" into Florida. As with all "Melaleuca" species, "M. quinquenervia" seeds prolifically. In the absence of natural predators, it spread throughout southern Florida; at one time it was estimated that it had colonised 12% of southern
