High sand

from Wikipedia, the free encyclopedia

A high sand or plate is a sandbank in the Wadden Sea that is so far above the mean tidal high water that it is only flooded during storm surges or not at all. Most of the high sands were formed from shallower sandbars. The high location enables vegetation, which in turn can increase the sand surface by holding on to drifting sand . A high sand can thus develop into a dune island over the years , it can hike or be removed to a shallower sandbank. Such an island formation process has been taking place on the high sand of Norderoogsand off the west coast of Schleswig-Holstein since the turn of the millennium. Another example of a high sand that developed into an island is Mellum off the coast of Lower Saxony .

Most of the high sands on the German North Sea coast are part of one of the national parks Schleswig-Holstein Wadden Sea , Lower Saxony Wadden Sea and Hamburg Wadden Sea or designated as a nature reserve , FFH or bird sanctuary .
