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|
|Important characterizing||Laminaria digitata||Oarweed|
|Important characterizing||Saccharina latissima||Sugar kelp|
|Important characterizing||Fucus serratus||Toothed wrack|
|Important characterizing||Halidrys siliquosa||Sea oak|
|Important Structural||Palmaria palmata||Dulse|
|Important Structural||Chondrus crispus||Carrageen|
|Important Structural||Ceramium virgatum||A red seaweed|
|Important Structural||Corallina officinalis||Coral weed|
|Important functional||Littorina littorea||Common periwinkle|
|Important functional||Patella vulgata||Common limpet|
Laminaria digitata, Saccharina latissima, Fucus serratus and Halidrys siliquosa have been selected as important characterizing species since they are faithful fucoids and kelps within the biotope (see Connor et al., 1997b). However, loss of any one of these species would not in itself result in loss of a recognizable biotope. Therefore, for the sake of sensitivity assessment the fucoids and kelps have been treated as a functional group.
Palmaria palmata and Ceramium virgatum have been chosen to represent the sensitivity of characteristic foliose and filamentous red algae, and Corallina officinalis to represent corallines. Littorinids, limpets and amphipods have been shown to be important grazers in rockpool environments (see 'ecological relationships') that affect community structure and development. Their sensitivities are represented by Littorina littorea and Patella vulgata. The sensitivity of amphipods is treated as a functional group, although reference has been made to relevant species reviews e.g. Hyale prevostii.
The MNCR database lists 667 species in 213 records of this biotope (JNCC, 1999), although not all species occur in all records of the biotope. Lewis (1964) noted that deep pools in the lower shore, especially in the southwest, are rich areas for collecting the rarer species of algae.
