Wetlands in the Tidal Freshwater Zone

摘要: Tidal freshwater wetlands occur in the upper part of estuaries Europe and North America (and likely elsewhere) experience tides up to several meters amplitude twice a day. They at interface between brackish zone estuary river; where fresh water mix is an area maximum suspended matter (i.e., turbidity zone). The tidal within plays important role overall patterns nutrient cycling for whole pattern appears differ saline sections. Although do not include many endemic or restricted species, they are characterized by high species habitat diversity. There distinct zonation flora fauna responding relationship surface elevation amplitude. dominant different America, but structure system life strategy fully comparable. also have common history being highly influenced human activities, resulting altered hydrology, losses wetland area, levels sediment input on both sides Atlantic Ocean. In recent years, restoration preservation activities been initiated there hope that will increasingly become elements estuarine systems provide free ecological services man nature.
