Species Not Established in U.S.

Provides examples of species of concern, not established in the United States, and why we must increase our efforts in early detection and rapid response (EDRR) and the prevention of new introductions. These species are also included in the Terrestrial and Aquatic Species Profiles.


Note: Our species profiles provide general information about species considered to be invasive. This is not a list of all invasive species, nor does our information have regulatory implications. The large numbers of invasive species prevent us from maintaining detailed information on ALL invasive species. In addition, determining the invasiveness of a species depends on a number of local factors, including type of habitat. Our species profiles are provided as an educational informational tool.
