Meaning of Marshland
Marshland is a treeless land in which the water table is at, above, or just below the surface of the ground. It is dominated by grasses, reeds, sedges, and cattails. These plants typify emergent vegetation, which has its roots in soil covered or saturated with water and its leaves held above water.
Llanrhidian Marsh
The salt marsh channels on Llanrhidian Marsh in South Wales slowly fill with water on the incoming tide, watched by a flock of oystercatchers and gulls. The diurnal cycle of the tides flooding and exposing the flats generates a unique ecosystem rich in marine life. Salt marshes are found in the intertidal zone along low-energy coastlines, forming along the margins of estuaries, where freshwater from the land mixes with sea water. The extensive root systems of salt marsh plants enable them to withstand strong winds, waves, and flooding from storms, and act as natural buffers against storm damage to upland development.
