A species translocated from one region or continent to another outside its normal range, particularly when the translocation is the result of human activity (intentional or otherwise). Many thousands of species, including animals, plants, fungi, bacteria, and viruses, have been transported to areas outside their native ranges and have successfully established new populations there. If one of these introduced species then causes significant negative ecological, economic, or human-health impacts, it is categorized as an invasive species (also termed a nonnative or nonindigenous species) [Fig. 1].
