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||Venerupis senegalensis||Pullet carpet shell|
|Important other||Mya truncata||Blunt gaper|
|Important other||Littorina littorea||Common periwinkle|
|Important other||Arenicola marina||Blow lug|
Venerupis senegalensis is the species which defines this biotope. It is dominant, highly faithful and frequent. Loss of the species would also result in loss of the biotope. However, loss of the species would be unlikely to have significant knock on effects for the rest of the community as there are other bivalve species in the biotope which fill similar niches. Venerupis senegalensis is therefore assessed as important characterizing and not key.
Other species in the biotope which should be considered when assessing biotope sensitivity are Littorina littorea, Arenicola marina and Mya truncata. They are therefore categorized as 'important other'. In the absence of a complete Biology and Sensitivity Key Information Review for Mya truncata the review of Mya arenaria has been used for reference.
