Markham's Triangle MCZ

Status: Proposed


Site overview

This site is located 137km from the Humberside coastline in the East of England, with depth ranges between 30-50m, and lies next to  the Cleaverbank Special Area of Conservation, another type of Marine Protected Area in adjacent Dutch waters. It is known that the harbour porpoise, grey seal and harbour seal all live and feed in this area. Worms dig into the seabed here, and in turn are a good food source for crabs, seals and dolphins.

At risk This site is at risk, it currently is not designated as a Marine Protected Area - but should be. Decision makers in England will determine in 2018 if this site should be protected, make sure your voice is heard. Take action to ensure this site becomes a properly protected area.
