IR.LIR.K.SLat.Pk Saccharina latissima park on very sheltered lower infralittoral rock
Published date 2015-03Silty bedrock or boulders with a Saccharina latissima park (often the cape-form). Beneath the canopy, the rock is covered by encrusting coralline algae, and the urchin Echinus esculentus is often pres...
SS.SMp.KSwSS Kelp and seaweed communities on sublittoral sediment
Published date 2015-03Shallow sublittoral sediments which support seaweed communities, typically including the kelp Saccharina latissima, the bootlace weed Chorda filum and various red and brown seaweeds, particularly fila...
CR.FCR.Cv.SpCup Sponges, cup corals and anthozoans on shaded or overhanging circalittoral rock
Published date 2015-03This biotope occurs on shaded and overhanging rock, such as on cave walls and ceilings although there are very few records of caves in conditions not subject to wave surge (i.e. deeper circalittoral h...
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
