A species that humans bring to an area where it did not previously occur is a(an): exotic species.
Exotic species are those that exist outside of their native geographic range, also known as alien, nonnative, nonindigenous, or introduced species. Exotic species are those that people have purposefully or accidentally introduced into ecosystems outside of the ones in which they have evolved. These introductions undoubtedly happen regularly in nature.
For instance, the Japanese native Kudzu (Pueraria lobata) was brought to the United States in 1876. Due to either a lack of imported individuals or inadequate adaptation to the ecosystem they join, the majority of attempts to introduce exotic species are likely to be unsuccessful. However, some species have preadaptations that can help them thrive even more in a novel setting.
