Concept: Atlantic and Mediterranean low energy infralittoral rock in the eunishabitats vocabulary

Back to vocabulary

Concept URI	http://eunis.eea.europa.eu/eunishabitats/A3.3
Preferred label	Atlantic and Mediterranean low energy infralittoral rock
Definition	Infralittoral rock in wave and tide-sheltered conditions, supporting silty communities with [Laminaria hyperborea] and/or [Laminaria saccharina] (A3.31). Associated seaweeds are typically silt-tolerant and include a high proportion of delicate filamentous types. In turbid-water estuarine areas, the kelp and seaweeds (A3.32) may be replaced by animal-dominated communities (A3.36) whilst stable hard substrata in lagoons support distinctive communities (A3.34).

Editorial note	There is a certain degree of duplication among some habitat classes in the EUNIS system coming either from BioMar or the Barcelona or HELCOM classifications. Therefore this means that all level 4 definitions (presently based on BioMar and Barcelona) should be checked, and given a new name if necessary. The biogeographic details are to be addressed in level 5 habitats.
