Phragmites Phragmites australis, also known as common reed or phragmites, is an invasive perennial grass that has spread rapidly throughout coastal and interior wetlands, riparian corridors, roadside ditches and other disturbed areas within the Great Lakes basin.

There are varieties of phragmites native to the Great Lakes region, but these grow more slowly and less aggressively than the non-native strain thought to have originated in Europe. Since introduction, the non-native strain of phragmites has spread pervasively through the Great Lakes region and other regions of the United States by both natural and human-driven dispersal mechanisms.

Due to its dense growth both above and below ground, phragmites can create stands 10-15 feet in height that effectively crowd and shade out native wetland and coastal species. As native assemblages are replaced by phragmites, species diversity is reduced and wildlife habitat quality is degraded. Dense phragmites stands can even alter the hydrologic regime of invaded wetlands by increasing evaporation and trapping sediment. Economic impacts of invasive phragmites infestations include reductions in property values and revenue loss from impacted recreational activities due to impeded access to coastal areas and restricted views.
