Preferred label [Pelvetia canaliculata] and barnacles on moderately exposed littoral fringe rock
Definition Exposed to moderately exposed steep, lower littoral fringe rock and mixed substrata characterised by the wrack [Pelvetia canaliculata] and sparse barnacles [Chthamalus montagui] and [Semibalanus balanoides]. On sheltered shores the biotope is restricted to vertical faces. The limpet [Patella vulgata] and the wrack [Fucus spiralis] are usually present as well. [P. canaliculata] typically overgrows a crust of the black lichen [Verrucaria maura] or on occasion [Verrucaria mucosa], in contrast to the red crust [Hildenbrandia rubra] on very sheltered shores. The winkle [Littorina saxatilis] is frequently present underneath the fronds of [P. canaliculata]. Some geographical variation are present and southern and western shores are typically characterised by the barnacle [C. montagui] or [Chthamalus stellatus] while [S. balanoides] dominates on northern and eastern shores. On mixed substrata the barnacle [Elminius modestus] may be present. Situation: PelB is generally found below the [V. maura] and barnacle zone (Ver.B; Ver.Ver). On exposed shores PelB is found above the biotope dominated by [F. spiralis] (Fspi) or the mussel [Mytilus edulis] and barnacles biotope (MytB) or the barnacles and [P. vulgata] biotopes (Sem). In addition, patches of lichen [Lichina pygmaea] with the barnacle [Chthamalus montagui] (Cht.Lpyg) may also occur at the same level or above this biotope, particularly on southern shores. On sheltered to extremely sheltered shores this biotope is limited to very steep or vertical faces.
