Invasive Species Information Center (NISIC): Gateway
to invasive species information; covering Federal, State,
local, and international sources.
Our new site will be available in the near future. We hope you find the updated site useful and easier to find invasive species information. See what NISIC's new home page will look like.
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.
