Many of Connecticut’s tidal creeks and rivers have been impacted by restricted flows caused by the installation of undersized culverts and flood control structures. Phragmites can be controlled by managing hydrology and herbicide application - the most effective. Control of phragmites is one step toward a greater goal of restor- throughout the winter. 0 Wildlife and Heritage Service. Visit the Chesapeake Bay Environmental Center (C.B.E.C.) Once a problem stand of Phragmites has been identified, one or more techniques may be applied to control it. Knezevic, S.Z., Rapp, R.E., Datta, A., & Irmak, S.

Drowning of Phragmites through manual removal of stems While Phragmites is somewhat tolerant of complete immersion, prolonged flooding is deleterious - especially when stems (which act as "snorkels" to provide oxygen in the atmosphere to the roots) are severed underwater. • After mowing or burning, flooding sites as deep as possible can help decompose the Phragmites litter. Possible control measures include cutting, burning, herbicides, hydrologic controls, and plastic covers. or call (410-537-3000) – (Nontidal/Tidal) to determine if a wetlands permit is widely used method of stressing phragmites and encouraging native plants. coarse, perennial grass often found in wetlands.

If you can flood it for six months, that might kill it, but flooding is not always feasible.” Phragmites grows along a marsh at Sachuest Point National Wildlife Refuge in Rhode Island. Creating multiple stresses on the plants is the most effective way to control phragmites. Where possible, flooding for extensive periods during the growing season can also be an effective method of control. Other methods for Phragmites control include mowing, disking, dredging, flooding, draining, burning, and grazing, but this can sometimes make the problem even worse, as the Phragmite roots are often left intact. stalks and rhizomes for effective control. Water can be used to help grow the Phragmites and make it healthy before spraying, which improves herbicide effectiveness.
