Phragmites Populations in Anoka County
ACD is monitoring invasive phragmites populations around the county this month. Phragmites australis is a tall invasive grass species that can take over wetland areas, riverbanks, lakeshores, and stormwater ponds if left untreated. ACD collaborates with partners to track and control its spread. This invasive grass has a native counterpart, Phragmites australis subspecies americanus. Native Phragmites has distinct red bands along its stem, whereas the invasive species has a pale blue-green color throughout its entire stem (see picture below).
If you notice tall grass (up to 15 feet) in a wetland, lakeshore, or roadside ditch near you, it is worth reporting on EDDMapS so that ACD staff can be aware of any new populations in the county. Follow a quick tutorial on how to use EDDMapS. For more information, contact Balin Magee, Resource Technician, at
