Silts and plates

Silts are areas outside the dykes without vegetation that are flooded with every high tide. When a silt is completely surrounded by water like an island, we call it a plate.

 

Many types of worms and shells live in the bottom of the plates and silts. They serve as food for the many bird species. The plates are also very important for the seals. They rest there and they suckle their young. To protect nature, you’re not allowed to walk on silts and plates when they dry up.

 

Only when silts become high enough, we see the first plants: Common Cord-grass and Glasswort. This can gradually lead to the formation of a salt marsh. A salt marsh is an area outside the dykes covered with plants, through which winding creeks run. During high tide these creeks are filled with water; they are dry at low tide. Only in case of extremely high water levels does the salt marsh flood. This means that plants growing on the salt marshes must be able to withstand salt water, such as glasswort and sea lavender.
