Carlingford Lough

Site overview: This site is a narrow, shallow sea lough that lies on the east coast of Ireland, located at the border of Northern Ireland and the Republic of Ireland. The area consists of sand and mudflats that provide key feeding grounds for birds. The muddy seabed is home to sea-pens and white sea slugs.
At risk: This site is not yet designated as a Marine Conservation Zone, which is a type of Marine Protected Area, but it should be. The government launched a consultation into this site, along with three others and are currently reviewing the responses. We urge them to designate this area as quickly as possible. Beneath the waves Seasearch, a nationwide network of scientifically trained scuba divers, responded to the government’s consultation on designating this site. This report noted that the slender sea-pens in this area are the most abundant the divers had ever seen in Northern Ireland.
