An invasive species is an exotic species whose introduction into an ecosystem in which the species is not native causes or is likely to cause environmental or economic harm or harm to human health. It is important to note that when we talk about a species being invasive, we are talking about ecosystem or environmental boundaries, not political ones.
Non-native species can be added to a community either by natural range extensions or because they are introduced as a result of human activity. Most non-native species have harmful ecological effects; these are referred to as invasive species. Virtually all ecosystems are at risk from the harmful effects of introduced invasive species (also see exotic species, marine invasive species, and aquatic invasive species).
