In the 2012 President's Budget Request, the National Biological Information Infrastructure (NBII) is terminated. As a result, all resources, databases, tools, and applications within this web site will be removed on January 15, 2012. For more information, please refer to the NBII Program Termination page.
The Nonindigenous Aquatic Species (NAS) site provides immediate access to new occurrence records through a real-time interface with the NAS database. Web site users can perform automatic queries to obtain lists of species according to State or hydrologic basin of interest. Fact sheets, distribution maps and news on new occurrences are continually posted and updated. The data is made available for use by biologists, interagency groups, and the general public.
