Sea-cliffs and rocky shores

Typologie des habitats de Saint-Pierre-et-Miquelon

Descriptif anglais

Rock exposures adjacent to the oceans, their connected seas and associated coastal lagoons, or separated from them by a narrow shoreline. The faces, ledges and caves of sea-cliffs and the expanses of rocky shore are important as reproduction, resting and feeding sites for seabirds, sea-mammals and a few groups of terrestrial birds, composing regionally distinct assemblies listed under unit 18.1. The presence of major sea-caves can be indicated by addition of codes of unit 12.7. Sea-cliffs may also harbour highly distinctive, specialized aerohaline plant communities with associated terrestrial faunas, listed under unit 18.2. Other terrestrial plant communities may belong to units 62, 61, 31, 32, 33, 34. The mediolittoral (intertidal or wave-washed) and supralittoral (spray) zones are inhabited by rich and diverse communities of invertebrates, fish and algae that have been listed under unit 11.29.
