Indigenous (ecology)

As autochthonous ( from Ancient Greek αὐτός cars, auto ' and χθών Chthon ' earth ' ), native or indigenous species is known in biology, organisms that in the current distribution area (region, habitat ) have emerged ( have formed evolutionarily ) or there without human influence immigrated in the wake of natural area enhancements. In botany, for example, speaks of trees of native species or varieties of indigenous varieties.

This compares to non-indigenous ( alien, sometimes exotic ) species that occur through the work of people in an area in which they do not occur naturally.
