Species indicative of sensitivity

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.

Species found especially in this biotope

  • Crepidula fornicata
  • Aphelochaeta marioni
Community Importance Species name Common Name
Important characterizing Crepidula fornicata Slipper limpet
Important characterizing Aphelochaeta marioni A bristleworm

Explanation

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'.
