At PAMF, we care about all these benefits, but there is only one that we monitor: controlling Phragmites invasions. Based upon experience obtained in Administration website: Bob Fitzgerald stands in a spot where frequent floods have killed 15 acres of soybean crops. Imazapyr is the active Introduction Phragmites australis subsp. 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. Creating multiple stresses on the plants is the most effective way to control phragmites. 0000002579 00000 n 0000001300 00000 n dense stands that provide little value for wildlife.

In tidal wetlands with unimpeded water flow >18 ppt, expansion of Phragmites is restricted to the high marsh/upland fringe (Marks et al., 1994), a distribution influenced by environmental stressors such as depth of flooding, salinity, and sulfide effects (Hellings and Gallagher, 1992, Chambers et al., 1998). Effective control of phragmites, particularly larger well- established stands, is likely to require multiple treatments using a combina- tion of methods. your property, available assistance programs, or obtain a list of licensed Maryland has lost nearly 45 percent of its wetlands.
