Sublittoral macrophyte-dominated sediment

English name: Sublittoral macrophyte-dominated sediment

Description (English)

This habitat type includes maerl beds, seaweed dominated mixed sediments (including kelps such as Laminaria saccharina and filamentous/foliose red and green algae), seagrass beds, and lagoonal angiosperm communities. These communities develop in a range of habitats from exposed open coasts to lagoons and are found in a variety of sediment types and salinity regimes.
