National Invasive Species Information Center (NISIC)

The gateway to invasive species information; covering federal, state, local, and international sources.

Invasive species are plants, animals, or pathogens that are non-native (or alien) to the ecosystem under consideration, and whose introduction causes or is likely to cause harm. Learn what determines if a species is invasive.
