Infralittoral rock in areas of significantly reduced or low salinity with Laminaria saccharina and associated seaweeds tolerant of these salinity conditions (e.g. green seaweeds, Phyllophora spp.). (Information taken from the Marine Biotope Classification for Britain and Ireland, Version 97.06: Connor et al., 1997a, b). NB. Laminaria saccharina is now considered to be a synonym of Saccharina latissima.

Additional information icon Additional information

The biotope SIR.LsacRS occurs as SIR.LsacRS.FIR with filamentous algae and sponges particularly characteristic in southwest Britain and as SIR.LsacRS.Phy, with Phyllophora crispa and SIR.LsacRS.Psa with Psammechinus miliaris especially characteristic in western Scotland.
