Nativenonnative

Nativenonnative is a term used to describe the ecological status of a species within a particular geographic region. A native species is one that occurs naturally in a region without human introduction. These species have evolved and adapted to the local environment over long periods. Nonnative species, also known as introduced, exotic, or alien species, are those that have been introduced to a region by human activities, either intentionally or accidentally.

The introduction of nonnative species can have a variety of impacts on an ecosystem. Some nonnative species may have no discernible effect, while others can become invasive. Invasive species are nonnative species whose introduction and spread threaten the environment, economy, or human health. These species can outcompete native species for resources, prey on native species, introduce diseases, or alter habitat structure.

Ecologists and conservationists often monitor the presence and impact of nonnative species. Efforts to manage or eradicate invasive species are frequently undertaken to protect biodiversity and ecosystem health. Understanding the distinction between native and nonnative species is crucial for effective conservation and environmental management strategies. The term nativenonnative is a concise way to refer to this ecological classification.
