Concept: Atlantic and Mediterranean moderate energy circalittoral rock in the eunishabitats vocabulary

Concept URI	http://eunis.eea.europa.eu/eunishabitats/A4.2
Preferred label	Atlantic and Mediterranean moderate energy circalittoral rock
Definition	Mainly occurs on exposed to moderately wave-exposed circalittoral bedrock and boulders, subject to moderately strong and weak tidal streams. This habitat type contains a broad range of biological subtypes, from echinoderms and crustose communties (A4.21) to Sabellaria reefs (A4.22) and circalittoral mussel beds (A4.24).
