Exotic species could be defined as any organism that happens to live outside its natural distribution range as a consequence of anthropogenic activity, or activities through deliberate or accidental introduction to a new habitat. Economic costs associated with exotic species include agricultural losses, damage to infrastructure, as when aquatic plants clog water intakes, and the costs of attempts to restore native species whose survival is endangered by introduced species .
