Preferred label [Enteromorpha] spp. on freshwater-influenced and/or unstable upper eulittoral rock
Definition Upper shore hard substratum that is relatively unstable (e.g. soft rock) or subject to considerable freshwater runoff is typically very species poor and characterised by a dense mat of [Enteromorpha] spp., though [Ulva lactuca] can occur as well. It occurs in a wider zone spanning from the supralittoral down to the upper eulittoral, across a wide range of wave exposures range. This biotope is generally devoid of fauna, except for occasional limpets [Patella vulgata], winkles [Littorina littorea] or [Littorina saxatilis] and barnacles [Semibalanus balanoides]. Situation: This band of green seaweeds is usually found above a zone dominated by a mixture [Enteromorpha] spp. and [Porphyra] spp. (EntPor) or a [Fucus spiralis] or [Fucus ceranoides] zone (Fspi; Fcer), and may replace the [Pelvetia canaliculata] zone (PelB). It can be found below a zone dominated by yellow and grey lichens. In very sheltered areas the seagrass [Ruppia maritima] can be found above this biotope while different wracks such as [Fucus] spp. can dominate the zone below (Rup; Asc; Fspi). Temporal variation: Seasonal fluctuations in the abundance of the [Enteromorpha] spp. and the occurrence of the other green seaweeds species will occur.
