Strangford Lough MCZ

Status: Designated


Site overview

Horse mussel reefs, seagrass beds, and rich seabeds exist in the inner SL site. This site was Norther Irelands’ only Marine Nature Reserve designated in 1995. It has since been designated as a Special Area of Conservation (for the seabed wildlife), and Special Protection Area (for the birds). The re-designation of the site as an MCZ over MNR has little bearing on current management measures that includes a ban on scallop dredging that was enabled thanks to legal action by Ulster Wildlife Trust in 2000.

At risk The ban on scallop dredging came too late to save the sites’ horse mussel beds, many of which haven’t recovered since the dredging was stopped in 2003.
