National Invasive Species Center

The National Invasive Species Information Center (NISIC) is located at the National Agricultural Library in Beltsville, MD near the intersection of U.S. Route 1 and Interstate Route 95/495 (Beltway Exit 25-North), 15 miles northeast of Washington, DC. See Google Map for our location.

To contact NISIC, users can use our Ask a Question form (preferred method and for quicker response), or may send postal mail to:

Our Web site is under continual development. We are interested in hearing any suggestions you have for improving this Web site, as well as descriptions of any other problems (typos, formatting errors, broken links) you have seen.

If you have suggestions or resources related to invasive species, please let us know about it if we don't have it included!

Ask A Question

If you have an invasive species related question for NISIC, or wish to give feedback, please submit an Ask a Question form. A valid email address is required for a response. Questions are answered by our NISIC Web Manager or a staff Librarian.

If you have a general agricultural related question (not related to invasive species), please contact NAL's reference staff for assistance.

Please note that we do not set laws or legislation, and we cannot identify species. We also cannot answer homework questions for you, but we can assist with your research.
