What is an invasive species?

An invasive species is a species that is non-native or alien to the ecosystem under consideration and whose introduction does or is likely to cause economic or environmental harm or harm to human health (EO13112).

An invasive species grows/reproduces and spreads rapidly, establishes over large areas, and persists.

Invasive species succeed due to favorable environmental conditions and lack of natural predators, competitors and diseases that normally regulate their populations.
