Holderness Inshore MCZ is a constantly-changing mix of rock, mud and soft sandy sediments
Uniquely characterised on the Yorkshire coast by extensive soft sediments and an ever-evolving landscape, the Holderness Inshore MCZ releases significant quantities of mud and sand into the North Sea each year. The sediment helps to create Spurn Head, providing protection for the Humber Estuary, as well as the shores and beaches of Lincolnshire.
The intertidal mud and sand are home to many species of worm, bivalves and small crustaceans, which are often buried in the damp sand. Just offshore in deeper waters, the site also supports commercially-important fish and shellfish species.
