Invasive Plants We Study: Phragmites
Invasive species are costly, disrupt natural ecosystems, and consequently threaten native species. Phragmites, a tall wetland grass, has been a part of U.S. wetlands for many years. However, a strain from Europe, introduced in the early 19th century, aggressively displaces the native strain and has spread across the U.S. and Canada. These aggressive invasive plants form highly dense stands that quickly outcompete native plants, degrade large areas of highly productive wetlands, drastically reduce habitat diversity and function, impair human use of beaches and recreational areas, and negatively impacts dependent wildlife and a multi-billion-dollar regional fishery.
