Wetlands of the United States

Their Extent and Their Value To Waterfowl and Other Wildlife

Plate 17

Marsh on Elliott Island, Dorchester County, Md. Dense needlerush, covering nearly 700,000 acres along the South Atlantic and Gulf coasts, produces no food for waterfowl. Recently, experimental needlerush control on Chassahowitzka National Wildlife Refuge in Florida has succeeded in replacing more than a hundred acres of this kind of marsh with vegetation attractive to waterfowl.
