The Maine Natural Areas Program has begun tracking and mapping terrestrial invasives throughout Maine. It is called the IMap program and is an effort to use “citizen scientists” to identify invasive plants as they spread across the State, mark the expansion of their spread, and identify effective methods to manage and/or control their spread into new areas. Check out the MNAP invasive page here. If you want their IMap page, select here and then check out the options on the right of their page.
