Preferred label | [Palmaria palmata] on very exposed to moderately exposed lower eulittoral rock |
Definition | Very exposed to moderately exposed lower eulittoral rock which supports a pure stand of dulse [Palmaria palmata] as a dense band or in large patches above the main kelp zone. [P. palmata] favours shaded or overhanging rock and often forms a band at the top of overhanging rock. Relatively low abundance of other seaweeds, such as the red seaweed [Porphyra umbilicalis] or the green seaweeds [Enteromorpha intestinalis], [Ulva lactuca] and [Cladophora rupestris] may also occur in this biotope although [P. palmata] always dominates. On the rock underneath the seaweed turf are the barnacle [Semibalanus balanoides] and the limpet [Patella vulgata and the olive-green lichen] Verrucaria mucosa. Sites should only be recorded as Pal where [P. palmata] forms a distinct band or occurs in large patches on the shore. Situation: This biotope is found below the biotopes dominated by the [P. vulgata, S. balanoides], the wrack [Fucus distichus] or [E. intestinalis] (Sem; Fdis; Ent). It is found above biotopes dominated by the kelp [Alaria esculenta] and [Laminaria digitata] (Ala.Ldig; Ldig.Ldig). Temporal variation: It is likely that the [P. palmata] biotope represents an opportunistic assemblage of fast-growing species which occupy gaps within or between the canopies of long lived perennials such as the wrack [Fucus serratus]. |
