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||Ascophyllum nodosum||Egg wrack|
|Important characterizing||Halichondria panicea||Breadcrumb sponge|
|Important characterizing||Ciona intestinalis||A sea squirt|
|Important structural||Fucus serratus||Toothed wrack|
The biotope consists of dense stands of Ascophyllum nodosum and other algae such as Fucus serratus are also common. The Ascophyllum nodosum is host to many different epiphytic sponges and ascidians represented here by Halichondria panicea and Ciona intestinalis.
