SS.SSa.IMuSa.FfabMag recorded () and expected () distribution in Britain and Ireland (see below)
For a list of 2004 characterising species please see the JNCC website.
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||Fabulina fabula||A bivalve|
|Important characterizing||Magelona mirabilis||A bristleworm|
|Important other||Chamelea gallina||Striped venus|
Magelona mirabilis and Fabulina fabula are the species which define this biotope. The loss of these species would result in the loss of the biotope. However, the loss of either of the species would be unlikely to have significant knock on effects for the rest of the community and therefore the species are ranked as 'important characterizing' not 'key'.
The venerid bivalve Chamelea gallina is not important for the viability of the characterizing species but should be considered when assessing the sensitivity of the community and hence is categorized as 'important other'.
