Twitter @juangangel In biogeography, a native species, indigenous species, or autochthonous species is a species that belongs to a specific region or ecosystem. Its presence in that region is the result of natural phenomena without human intervention.1 All natural organisms, in contrast to domesticated organisms, have their distribution area within which they are considered native. Outside that region, if they are brought by humans, they are considered introduced species. For example, the Argentine ant Linepithema humile is a species native to Argentina, Uruguay, Paraguay, and southern Brazil. It was accidentally brought to other parts of the world, including Africa, Europe, Australia, New Zealand, Japan, and North America, where it has established itself as an introduced species. A native species is not necessarily endemic. In biology and ecology, endemic means native exclusively to a specific biota. An indigenous species can occur in more than one location. For example, two species of African cranes: the Anthropoides paradisea, or paradise crane, is native and endemic to southern Africa, while the Bugeranus carunculatus, or wattled crane, is native to southern and northern Africa. The latter has a wider distribution and is therefore not considered endemic. Neither does it mean that it originated in that location. Species can move or be moved to other locations where they establish themselves during the course of their evolutionary history. The set of native species constitutes the native flora and fauna. They are well adapted to each other and form an ecosystem. When native species are destroyed or other species are introduced, this balance is altered, and the ecosystem can become degraded to the point where it cannot restore itself. In some cases, efforts are made to restore the vegetation and fauna of degraded sites, which requires careful planning. Certain species cannot be reestablished unless others are already present, meaning a succession process is necessary, starting with the planting of pioneer species, followed by secondary species, and ending with climax species.
