The following is an extract from an interesting post I recently came across, giving a useful insight into the saltmarsh coast of Norfolk, the subject of my current artworks :
In Norfolk there are amazingly few habitats which are self-forming and self-maintaining – which therefore require no intervention from conservationists to keep them as they are – and almost all of them are associated with the sea, its winds, its waves and its tides.
… the tide … helps make two fascinating and oft-ignored Norfolk habitats. Two of the wildest, least human-led habitats in Norfolk at that: mudflat and saltmarsh. In areas sheltered from the intense energy of the waves, such as enclosed bays and the harbours behind spits, the finest sediments in the water – tiny particles of silt – are deposited at the top of the tide, where the water has least energy. These particles cling to one another and where they are not shifted by subsequent tides they form a tenuous, easily-moved mudflat. Where conditions allow, filamentous algae colonise the mudflat, followed by what botanists call glasswort and in Norfolk we call samphire. These plants stabilise the flat and encourage more silts and clays to settle.
A saltmarsh is born.
