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. In addition, decomposing Phragmites can raise the surface elevation of the marsh more rapidly than would occur with slower-growing native salt marsh vegetation.

Higher elevations reduce saltwater flooding, depriving the Wildlife and Heritage Service plan to disturb wetlands through filling, excavating or vegetation removal, you Once a problem stand of Phragmites has been identified, one or more techniques may be applied to control it. 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). trailer The Mapper consists of three integrated components: A distribution map of large (> 0.2 ha) stands of existing Phragmites.
