Early Detection and Rapid Response (EDRR) Species
We are fortunate that many regions in northwest Michigan do not yet contain populations of some plants that have proven highly aggressive in other parts of the state/country.  Land management professionals categorize these species as “early detection and rapid response” (EDRR).  You can also learn more about ISN's EDRR efforts.
​
The list below outlines species that are not presently found in ISN's service area, or are found in low numbers, but have the propensity to cause harm if they become established. If you think you see any of these species, please report its location through the Midwest Invasive Species Information Network or contact ISN directly. If you are looking for a more extensive list, please check Michigan's Watch list or the Midwest Invasive Plant Network's early detection and response page.
