What are phragmites?
Phragmites, or common reed, is a tall grass that is generally be found in wet areas such as wetlands, lakeshore, and roadside ditches. 

Mature plants have sharp edges and rootstalks are very deep in the ground, making it impossible to remove by hand.

Phragmites crowd out native plants and animals, blocking views, reducing access for swimming, fishing and hunting.

Early detection is key to preventing large dense stands and reducing treatment costs. For information on how to identify phragmites download the Phragmites- Native or Not? pamphlet
