Common Reed is a tall, aggressive grass of wetlands that forms dense monocultures in marshes and wet areas across North America. A native subspecies exists alongside a more aggressive introduced subspecies that has invaded and degraded many coastal and inland marshes. Despite its invasive reputation, it provides important cover for marsh birds and mammals.
