To assess the sensitivity of the biotope, the sensitivity of component species is reviewed. Those species that are considered to be particularly indicative of the sensitivity of the biotope, and for which research has been undertaken in detail are shown below (see selection criteria). The biology of other component species of the biotope is also taken into account wherever information is known to the researcher.
|Community Importance||Species name||Common Name|
|Key structural||Semibalanus balanoides||An acorn barnacle|
|Key structural||Patella vulgata||Common limpet|
|Important functional||Nucella lapillus||Dog whelk|
The biotope is characterized by a dense covering of barnacles, represented by Semibalanus balanoides (although the chthamalid barnacles Chthamalus montagui and Chthamalus stellatus can be the dominant barnacle in the south-west), and the limpet Patella vulgata. The dog whelk, Nucella lapillus, is a predator of barnacles and has been included because the species may influence the abundance of barnacles on the shore.
