Unstable boulders and cobbles in very shallow water may be seasonally disturbed which prevents a stable Laminaria hyperborea forest from developing. Seasonal movement of the substratum results in a community of the opportunistic kelp Laminaria saccharina, Chorda filum and Desmarestia spp. with encrusting algae and sediment-tolerant seaweeds. The shallowest areas of the Sarns in Cardigan Bay are typical examples of this biotope. (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.
