salt marsh Vegetation often found on mud banks formed at river mouths, showing regular zonation reflecting the length of time different areas are inundated by tides. Sea-water has a high salt content which produces problems of osmotic pressure for the vegetation, so that only plants that are adapted to this environment (halophytes) can survive.
