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||Halcampa chrysanthellum||A sea anemone|
|Important characterizing||Edwardsia timida||A sea anemone|
There is very little information available to indicate likely sensitivity of characteristic or other species of community importance in the biotope. Assessment of sensitivity and recoverability relies on a general knowledge of biology of biotopes where the surface layer of biota is likely to be disturbed occasionally but infauna species are likely to be long-lived and have stable populations.
