Preferred label	[Laminaria saccharina] and red seaweeds on infralittoral sediments
Definition	On infralittoral mixed muddy substrata communities characterised by the kelp [Laminaria saccharina] and mixed filamentous and foliose red algae can be found. This biotope contains a number of sub-biotopes distinguished by the degree of either wave or tidal exposure. In moderately strong tidal streams in exposed areas [Laminaria] is sparse and dense stands of red seaweeds are found attached to the boulders and cobbles that make up a large proportion of the sediment (LsacR.CbPb). As the degree of wave and/or tidal exposure decreases there is a change in community structure, with the density of [Laminaria] and the diversity of red algal species increasing (LsacR.Gv). As the environment becomes more stable a number of brown algal species are able to inhabit this environment and a rich infauna develops (LsacR.Sa). In the most sheltered examples of this biotope a diverse muddy sediment infauna can be found and the ['Trailliella'] phase of [Bonnemaisonia hamifera] may develop (LsacR.Mu).
