IR.LIR.K.Slat Saccharina latissima on very sheltered infralittoral rock
Published date 2015-03Very sheltered infralittoral rock dominated by the kelp Saccharina latissima. Typically very silty and often with few associated seaweeds due to siltation, grazing or shading from the dense kelp canop...
IR.LIR.Lag.FChoG Mixed fucoids, Chorda filum and green seaweeds on reduced salinity infralittoral rock
Published date 2015-03Permanently submerged mixed fucoids on rock in lagoons. The main species are the wracks Fucus serratus and Fucus vesiculosus, but the brown seaweeds Chorda filum, Ascophyllum nodosum and Ectocarpaceae...
LR.HLR.FR Robust fucoid and/or red seaweed communities
Published date 2015-03This biotope complex encompasses those seaweeds that are able to tolerate the extreme conditions of very exposed to moderately exposed rocky shores. The physical stresses caused by wave action often r...
IR.LIR.K.LhypSlat.Pk Mixed Laminaria hyperborea and Saccharina latissima park on sheltered lower infralittoral rock
Published date 2015-03Sheltered silted, bedrock and boulders with a park of mixed Laminaria hyperborea and Saccharina latissima. Both kelp species are sparse in the park (Frequent). Beneath the often 'cape-form' kelp canop...
