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||Crepidula fornicata||Slipper limpet|
|Important characterizing||Aphelochaeta marioni||A bristleworm|
Crepidula fornicata and Aphelochaeta marioni are both species which define this biotope. The loss of these species would result in the loss of the biotope. However, the loss of either of the species would be unlikely to have significant knock on effects for the rest of the community and therefore the species are ranked as 'important characterizing' not 'key'.
