Concept URI http://eunis.eea.europa.eu/eunishabitats/A2.312
Preferred label [Hediste diversicolor] and [Macoma balthica] in littoral sandy mud
Definition Mainly mid and lower shore sandy mud or mud in lower estuaries, sheltered bays and marine inlets, often subject to variable salinity. The main characterising species are the ragworm [Hediste diversicolor], the baltic tellin [Macoma balthica], and the oligochaetes [Tubificoides benedii] and [T. pseudogaster]. Further polychaetes that are often common or abundant include [Pygospio elegans], [Streblospio shrubsolii], [Tharyx killariensis], [Aphelochaeta marioni], [Capitella capitata] and [Manayunkia aestuarina]. The oligochaete [Heterochaeta costata] and the mud shrimp [Corophium volutator] may be abundant. The spire shell [Hydrobia ulvae] is often common. Other species which occur in a significant proportion of samples include the polychaetes [Eteone longa] and [Nephtys hombergii], and bivalves such as the cockle [Cerastoderma edule] and [Abra tenuis]. The sand gaper [Mya arenaria] is superabundant in about a quarter of the samples for this biotope. [M. arenaria] is probably present in a higher proportion of areas of this biotope, but may be missed in core samples due to its size. Situation: HedMac may occur on the mid/lower shore of lower estuarine shores, with HedMacEte or MacAre on the upper shore. HedMacScr, Hed.Str, NhomAph, and Hed.Cvol may be present on the same shore. Temporal variation: [Enteromorpha] spp. and [Ulva lactuca] may form mats on the surface of the mud during the summer months, particularly in areas of nutrient enrichmnent.
