Point data based on records in the UK Marine Recorder Snapshot.
Moderately exposed shores (bedrock, boulders and cobbles) characterised by mosaics of barnacles and fucoids on the mid and upper shore; with fucoids and red seaweed mosaics on the lower shore. Where freshwater or sand-scour affects the shore ephemeral red or green seaweeds can dominate. Other shores support communities of mussels and fucoids in the mid to lower shore. Two biotope complexes have been described: Mussels and fucoids (MusF) and barnacles and fucoids (BF).
