Non-native Phragmites, also known as common reed, is a perennial, aggressive wetland grass that displaces native plant and animal species. Invasive Phragmites is one of the most widespread plants on Earth and is found worldwide. In the U.S. it grows in the eastern states particularly along the Atlantic Coast and increasingly across the Midwest and Pacific Northwest. It is usually an indicator of a wetland ecosystem that is out of balance. (click on thumbnails below for caption info)
