In biogeography, a native species is indigenous to a given region or ecosystem if its presence in that region is the result of only local natural evolution (though often popularised as "with no human intervention" The term is equivalent to the concept of indigenous or autochthonous species. Every wild organism (as opposed to a domesticated organism) is known as an introduced species within the regions where it was anthropogenically introduced. If an introduced species causes substantial ecological, environmental, and/or economic damage, it may be regarded more specifically as an invasive species.
The notion of nativity is often a blurred concept, as it is a function of both time and political boundaries. Seen over long periods of time, plants and animals take part in the constant movement of tectonic plates—species appear and may flourish, endure, or become extinct, and their distribution is rarely static or confined to a particular geographic location.
A native species in a location is not necessarily also endemic to that location. Endemic species are exclusively found in a particular place. A native species may occur in areas other than the one under consideration. The terms endemic and native also do not imply that an organism necessarily first originated or evolved where it is currently found.
