EUNIS habitat type code   A1.327 Level   5
Edition   EUNIS Habitat Classification 2012 - a revision of the habitat classification descriptions.

Description ( English )

Very sheltered to extremely sheltered bedrock and stable boulders in the eulittoral zone that are subject to reduced salinity and characterised by the wrack [Fucus ceranoides]. Species richness is typically low in this biotope. The green seaweeds [Enteromorpha intestinalis] and [Ulva lactuca] may be present together with the crab [Carcinus maenas] and the occasional barnacle [Elminius modestus] and [Semibalanus balanoides]. Situation: As [F. ceranoides] is more tolerant of reduced salinity than the other fucoids, [F. ceranoides] tends to replace the wracks [Fucus spiralis], [Fucus vesiculosus] and [Ascophyllum nodosum] towards the upper reaches of estuaries and sea lochs or in areas with freshwater influence. This biotope may, however, still contain other fucoids, although [F. ceranoides] always dominates. This biotope is often found on artificial substrata such as sea defences or bridge supports.
