South Rigg MCZ

Status: Proposed


Site overview

This site is currently being considered for protection by the government! South Rigg is an area of the Irish Sea, between the waters of Northern Ireland to the west, Scottish waters to the north and Isle of Man waters to the east. It’s a pretty deep site ranging from 50 to 150 meters but if you could see the seabed you’d be amazed! It is home to the ocean quahog - a type of clam which can live for up to 400 years! Seapens also live here along with burrowing worms - which larger animals then feed on. The site also contains Irish Sea Mounds. These are a group of bedrock outcrops rising out of the deep.
