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.
