Saltwater Aquatic Vegetation
Végétation aquatique d'eau salée


Saltwater Aquatic Vegetation wetlands are distinct wetlands transitional along the coast between the intertidal salt marshes or other intertidal areas, and permanent, deep water oceans. More rarely they occur in inland saline habitats. The lower limits of salinity are set at 0.5 ppt, below which it is considered freshwater. Submerged or floating-aquatic plants usually dominate the vegetation, with less than 10% of the surface water area occluded by standing emergent or woody plants. Macroalga may be common. Open surface water at a range of depths is present for all or most of the year.
