Phragmites is a perennial and aggressive wetland grass that grows over 10 feet tall and is easily recognized by its height and fluffy seed heads. Phragmites have very little value to the diverse populations of wildlife in the marsh. Their thick growth and rapid spread choke out valuable plants and reduce the biodiversity of the marsh's delicate and highly- valued ecosystem.
