Markham's Triangle MCZ
Part of the North Sea about 137km from the Humberside coastline, Markham’s Triangle is a mix of habitats including sand, mud and gravel which is fished extensively by UK and European bottom-trawlers. These unassuming habitats are vital homes for a plethora of worms, burrowing molluscs and crustaceans, which in turn provide food for the fish we eat. This site would protect an important part of the food chain on which we ourselves depend.
There are very few sites that lie beyond 6nm and are properly protected in English seas. MCS believes this site should be considered for designation as a Highly Protected Marine Area where all human activities that negatively impact marine wildlife are prohibited.
MPA TypeMarine Conservation Zone
Marine Conservation Zones (MCZs) are designated under UK legislation (Marine and Coastal Access Act 2009) and have been established around England, Wales and Northern Ireland to contribute to the UK MPA network protect a range of nationally important marine wildlife, habitats, geology and geomorphology, and can be designated anywhere in English and Welsh territorial and UK offshore waters.

A very rich and diverse muddy undersea habitat that supports high numbers of worms, cockles and other shellfish, urchins and sea cucumbers as well as sea pens, burrowing anemones and brittlestars.
Sandy seascapes that can seem a bit like deserts, but can be full of life. Flat fish and sand eels camouflaged on the surface of the sand,worms and bivalves (with their paired, hinged shells) all live in places like these.
Subtidal coarse sediment
Undersea beds of coarse sand, gravel and shingle. Most of the animals that live here, like bristleworms, sand mason worms, small shrimp-like animals, burrowing anemones, carpet shell clams and venus cockles, are found buried in the seabed – the safest pl
Subtidal mixed sediments
Undersea beds of a mixture of stones, gravels, sands and muds. Because mixed seabeds are so varied, they may support a wide range of animals, both on and in the sediment.
