Grass Family - Sawgrass, Sedges, Rushes & More Management


Ecological Importance

Aquatic grasses can be found growing in damp places or in the water emerging above the water's surface. Burr-reed, Bottle Brush Sedges, Bulrushes, Giant Cutgrass, Giant Foxtail, Maidencane, Paragrass, and Sawgrass are just a few for the aquatic grass species serving vital roles for a healthy aquatic ecosystem. Aquatic grasses provide habitat and food to all manner of amphibians, fish and wildlife while stabilizing shorelines and filtering nutrients.


In most cases, members of the grass family do not create any problem other than blocking the view for owners of lakes and ponds. Dense growth may hinder recreational activity. Selective control should be used in areas where problems occur.
