Bae Cemlyn/ Cemlyn Bay SAC
The lagoon here is thought to be the best example of a saline coastal lagoon in Wales. It is separated from the sea by a shingle bank with a narrow channel at the western end, across which a sluice system was built in the 1930s. Seawater mixes with freshwater via this sluice and, in storms, the waves can get so big that they go over the top. This is a really unique environment, and certain types of animals which only live in lagoon areas are found here, such as the lagoon cockle and the lagoonal mud-snail. Some rare plant species grow within the lagoon, including the brackish water-crowfoot and beaked tasselweed.

Over 500,000 records on undersea habitats and species have been collected by volunteer Seasearch divers providing significant evidence for inshore ‘marine protected areas’
An area over 9 times the size of Wales is now in marine protected areas in the UK, but less than 1% is considered by MCS scientists to be well managed
Over half a million people have voiced their support for ‘marine protected area’ designation in the UK through our campaigns
