Salt marshes form a rare type of nature area, with a unique flora and fauna. Low marshes are almost always inundated with water during high tide while high-lying marshes only flood during tidal storms. Due to the regular salt bath on the marshes, only those plants resistant to a high salinity level in the soil are able to grow. There is a big difference between low and high marshes. In this way, salt marshes gradually expand and grow higher.
Sand and mud particles, suspended in the seawater flooding the marshes, subside among the plants and don’t easily wash away. Salt marshes are also found in the delta region, where the local people call them ‘schorren’. Salt marshes flood with seawater during extremely high water levels or storms. They usually lie adjacent to shallow tidal areas, such as the Wadden Sea.
Salt marshes are pieces of land directly bordering the sea there are no dunes or dikes in between.
