Concept: [Fucus spiralis] on full salinity upper eulittoral mixed substrata in the eunishabitats vocabulary

Concept URI http://eunis.eea.europa.eu/eunishabitats/A1.3122
Preferred label [Fucus spiralis] on full salinity upper eulittoral mixed substrata
Definition Moderately exposed to sheltered full salinity upper eulittoral mixed substrata characterised by a band of the wrack [Fucus spiralis]. Occasional clumps of the wrack [Pelvetia canaliculata] can be overgrowing the black lichen [Verrucaria maura] and the olive green lichen [Verrucaria mucosa]. On the more stable boulders underneath the fronds the red crust [Hildenbrandia rubra] can be found along with the barnacle [Semibalanus balanoides] and the limpet [Patella vulgata]. The winkles [Littorina littorea] and [Littorina saxatilis] can be found on and among the boulders and cobbles, while amphipods and the crab [Carcinus maenas] can be present either underneath the boulders or among the brown seaweeds. The green seaweed [Enteromorpha intestinalis] can occur in some abundance especially during the summer. Situation: This zone usually lies below a zone dominated by the wrack [P. canaliculata] (PelB; Pel). Vertical surfaces in this zone, especially on moderately exposed shores, often lack the fucoids and are characterised by a barnacle-limpet dominated community (Sem).In areas of extreme shelter, such as in Scottish sea lochs, the [P. canaliculata] and [F. spiralis] zones often merge together forming a very narrow band. Fspi.X occur above the wracks [Ascophyllum nodosum] (Asc.X) and/or [Fucus vesiculosus] (Fves.X) zones. These two fucoids may also occur among the [F. spiralis], although [F. spiralis] always dominates. Fspi.X can also be found above a barnacle [S. balanoides] and winkle [L. littorea] dominated biotope (BLitX). Temporal variation: Ephemeral green seaweeds such as [E. intestinalis] can occur in some abundance during the summer when the growth conditions are optimal.
