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.

Community Importance Species name Common Name
Important characterizing Chorda filum Sea lace
Important characterizing Saccharina latissima Sugar kelp
Important functional Asterias rubens Common starfish
Important other Arenicola marina Blow lug

Explanation

Saccharina latissima and Chorda filum characterize the biotope and it would not be IMX.LsacX without them. Asterias rubens and Arenicola marina both occur in small numbers but represent species that are important predators and bioturbators respectively.
