Invasive vs. Non-native Species

A non-native species is one that does not occur in a particular environment naturally, but has been introduced by human causes either accidentally or on purpose and has developed a stable breeding population. Many non-native species are also considered invasive, meaning that their unnatural presence causes economic or environmental harm or harm to human health. This is often because the non-native species has no natural predators in its introduced environment, so there is little population control and populations are able to reach higher numbers than the ecosystem can healthily support. It is also possible for a native species to be considered invasive, especially when predators are removed and the increased population of the native species becomes harmful for the environment, economy, or human health. Non-native invasive species have become the single greatest threat to the Refuge System and the U.S. Fish and Wildlife Service's core wildlife conservation mission impacting natural habitats and native plants and animals, including threatened and endangered species.
