Sea-cliff faces, seaside rocks

Typologie des habitats de Saint-Pierre-et-Miquelon

Descriptif anglais

Palaearctic hard rock sea-cliffs, their faces, ledges and associated caves, rocky shores and isolated seaside rocks, their associated seabird, sea mammal, wader and, in a few cases, terrestrial passerine, communities. The presence of vascular aerohaline vegetation should be indicated by use of the appropriate code from unit 18.2, that of mediolittoral (intertidal or wave-washed) and supralittoral (spray) zone communities of marine invertebrates, lower vertebrates and algae, by use of codes from unit 11.29. Less salt-influenced communities, in particular of units 62, 61, 31, 32, 33, 34, may contribute to the colonisation of the cliffs.
