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||Fucus distichus||A brown seaweed|
|Key structural||Fucus spiralis||Spiral wrack|
The biotope is a fucoid dominated community characterized by Fucus distichus and Fucus spiralis f. nana. Although several other species are present in the biotope it is the sensitivity of the fucoids that are important in determining the sensitivity of the biotope.
