MB4-222 - Végétation d'eaux saumâtres dominées par Phragmites australis dans du sédiment hétérogène de l'infralittoral en milieu à salinité réduite en Atlantique

Vegetation of brackish waters dominated by Phragmites australis in reduced salinity Atlantic infralittoral mixed sediment

Classification des habitats EUNIS 2022

Descriptif de l'habitat

Permanently low salinity muds or peaty muddy sands with some gravel which supports Phragmites australis reed beds. These reed beds are often found in enclosed water bodies influenced by freshwater inflow and may have notable quantities of decaying reed material. The substratum may be mixtures of mud, peaty mud, sand and some gravel. Filamentous green algae and charaphytes such as Lamprothamnium papulosum and Chara aspera may also be found in association with this biotope as well as a the freshwater quillwort Myriophyllum spp. The infaunal component of this biotope is poorly known. This biotope is further described as NVC type S4 in the British National Vegetation Classification (Rodwell 1995).
