GLDIATR searches for species identified as of concern or invasion risk to the Great Lakes region based on the following:

If you would like to learn more about using GLDIATR, or if you are aware of any newly regulated species or species of emerging concern that should be added to this effort, please contact Erika Jensen (ejensen@glc.org). Illinois-Indiana Sea Grant developed a searchable database of regulations available here.
