Phragmites – otherwise known as the common reed – are an invasive, perennial tall grass often found in wetlands or surrounding ponds and lakes. They are easily distinguished by their tall heights, which can reach fifteen feet, and feathery seed plumes.
What makes phragmites so troublesome? Phragmites are an invasive species that has spread throughout North America via railroads, roadways, habitat disturbances and shoreline development.
While they may start as unobtrusive patches – and may even be aesthetically pleasing initially – they can spread quickly, choking out native plants and waterbodies.
As they grow and take over native spaces, Phragmites devalue properties and communities, rendering areas unusable and unsightly. Left unchecked, they can wreak havoc on the local ecosystem, waterbodies, wildlife, plants, recreation and more:
Phragmites’ feathery plumes appear in June and fill with seeds by August. During September, they cross-pollinate before shedding and spreading their seeds in the fall and early winter.
During winter and its subsequent frosts, each phragmites plant stores nutrients in its rhizomes underground. In the spring, this rhizome network germinates new seedlings. This is how the plant sustains itself even as its stems, plumes and leaves turn brown and die off.
Clarke provides a complete assessment of your community’s Phragmites outbreak, combined with a selection of control methods to work with your needs and budget.
Clarke’s team conducts surveys via foot or Utility Task Vehicles to accurately chart
areas in need of treatment. Our in-house mapping department uses this data to create
guides for aerial and ground applications.
As Phragmites often grow in remote, difficult-to-reach areas, Clarke tailors every
application to provide the best method of control for each case:
Clarke brings a wealth of experience and knowledge to successfully addressing aquatic invasive species, including Phragmites, for municipalities, agencies at the national, state and local levels as well as lake associations and subdivisions.
Our in-house staff includes biologists, environmental scientists, regulatory agents, helicopter pilots and licensed applicators, each working to keep Clarke OSHA compliant, DOT certified and NPDES compliant.

How did our aquatics team get this background pond wedding-party-ready within a tight two-week deadline? Read on to find out.
Two Clarke facilities in Illinois have officially been recognized as LEED Certified by the U.S. Green Building Council.
An aeration system – which can include pond fountains, aerators, diffusers and more – is an easy, natural way to supply man-made and natural ponds with dissolved oxygen. Aquatic animals, such as fish and aquatic invertebrates, require DO to breathe and function.
