Other Site Characteristics

Valencia Harbour and the Portmagee Channel is an inlet that is located on the south-west coast of Ireland in the lee of Valencia Island. Bedrock is Old Red Sandstone. The site is sheltered and shallow, and it contains a variety of sediments, which range from a mixture of cobbles, pebbles and gravel to very soft mud. Several small islands occur at the entrance to Portmagee Channel.

4.2 Quality and importance

The site contains important and good quality examples of large shallow inlets and bays, intertidal sand and mud flats, and reefs, and has several species of high conservation importance that do not occur in the rest of the country. There is a seagrass bed in the sublittoral fringe at the northern entrance to the Portmagee Channel. To the south of the seagrass bed, in the muddy sediments at the north mouth of the channel at approx. 5m BCD, is an extraordinary community: two important species of burrowing anemone occur in addition to two scarce nudibranch species, scarce and vulnerable sea pens and an echinoderm of conservation importance. Perhaps most noteworthy is the anemone Edwardsia delapiae, which was first described from Zostera marina beds on the shore at Valencia Island. It had not been recorded since its original description in 1928 until the BioMar survey rediscovered a small population occurring in fine mud. Other sediment communities in Valencia Harbour and the Portmagee Channel are characterized by the delicate seapen, Virgularia mirabilis. Additional important sediment communities are the maerl beds that occur where currents are stronger in the narrows at the south of the Portmagee Channel and the representative estuarine sediment community on the shore of the Valencia River. The reef communities within the site are also of importance. The littoral reefs have an unusually high number of community types (16). On the north coast of Valencia Island is a small population of the purple sea urchin, Paracentrotus lividus. The unusual hydroid, Aglaophenia kirchenpaueri is present in the infralittoral reefs of Valencia Harbour, and species richness there can be high (70 species) in the upper infralittoral reef west of Perch rock. The ascidian Pycnoclavella aurilucens is present in both infralittoral and circalittoral communities. Phoronis psammophila is a rare phoronid species that is not recorded from the British Isles, but was recorded by BioMar on three occasions, all of which were in the Valencia Harbour/Portmagee Channel area.
