What term describes the introduction of non-native species into a new environment?

The term that describes the introduction of non-native species into a new environment is "invasive species." Invasive species are organisms that are brought into an ecosystem where they do not naturally occur, often as a result of human activity. When these species establish themselves in their new environment, they can outcompete, displace, or even eradicate native species due to their often rapid reproduction and growth rates. This can lead to significant ecological disruption, affecting biodiversity and ecosystem health.

The implications of introducing invasive species can be profound, as they can alter habitat structure, nutrient cycles, and the overall functioning of the ecosystem. This term is distinct from concepts such as habitat restoration, which involves repairing damaged ecosystems; population decline, which refers to a decrease in the number of individuals within a species; and conservation management, which focuses on protecting and managing natural resources. Each of these concepts addresses different aspects of wildlife ecology and conservation, while "invasive species" specifically pertains to the impact of non-native organisms on local ecosystems.
