Phragmites australis is an uncommon term for an increasingly common sight in the wetlands and along the beaches of the Great Lakes. It’s the scientific name for the common reed, a fast-growing perennial wetland grass.
An immigrant from Europe, it’s an exotic species that has a reputation for taking over any wetland real estate it visits.
Phragmites is a formidable foe. It roots easily, digs in deep and shoots runners along the ground in every direction, sprouting new plants all along the way. The reed grows tall — as high as 15 feet — and has stalks that can slice like a well-sharpened knife. It provides no food for birds and no shelter for wildlife. In fact, it threatens their very existence.
Until now, no one has done a comprehensive map showing where Phragmites is established and where it is spreading in the Great Lakes basins. The Michigan Tech Research Institute, based in Ann Arbor, has taken on the job. more
