EIR.LsacSac is one of several biotopes that occur on scoured bedrock or mobile substratum conditions. The various biotopes have mixtures of species that include Laminaria saccharina and Saccorhiza polyschides and are typically in the MIR.SedK group of sand or gravel-affected or disturbed kelp and seaweed communities. The likely closest related biotope is MIR.SedK.Sac (Saccorhiza polyschides and other opportunistic kelps on disturbed sublittoral fringe rock) which occurs mainly in southwest Britain. Altogether, these biotopes occur widely in the British Isles including in south-west Britain, all along the west coast of Britain and on the north-east coast. European Union Nature Information System (EUNIS) Habitat classification code: A3.116 - [Laminaria saccharina] and/or [Saccorhiza polyschides] on exposed infralittoral rock (Davies & Moss, 1998).
