CMECS:532 This class aligns to the Coastal and Marine Ecological Classification Standard (CMECS). In ENVO, we may adapt the definition for consistency, but the semantics (meaning) of the term should be unaffected. Please consult the CMECS catalogue (https://cmecscatalog.org/) for authoritative and semantically unconstrained definitions. From the CMECs definition: "Areas where mussels have constructed substrate are classified as Mussel Reef. Areas where mussels are not attached to a hard substrate are classified as Soft Sediment Fauna, Mussel Bed." area of attached faunal communities mussel reef
