A species is on this list when the country's checklist in the Global Register of Introduced and Invasive Species records it as introduced by people and present. It is marked invasive when the checklist records an impact on native wildlife or habitats. A species can be native to one part of a country and introduced in another, and checklists are revised as countries report, so the list is not final.
