Very exposed lower eulittoral rock on some shores supports a band of dense Corallina officinalis with low abundances of other turf-forming red algae such as Lomentaria spp., Mastocarpus stellatus, Ceramium spp. and Osmundea pinnatifida (=Laurencia pinnatifida), the red encrusting alga Callithamnion spp. and the brown alga Scytosiphon lomentaria. The coralline turf also creates a micro-habitat for small animals such as spirorbid worms. The brown alga Bifurcaria bifurcata and the barnacle Balanus perforatus may occur in the extreme south-west. This community usually forms a distinct band just above the kelp zone (EIR.Ala, EIR.Ala.Ldig or MIR.Ldig).
