D4.1C - Niveau 4 : Bas-marais alcalins à Carex rostrata
Description
Alkaline fen communities dominated by Carex rostrata, accompanied by a carpet of brown mosses, sometimes with basicline sphagna, and few vascular plants other than sedges, occupying very wet sites in rich fen complexes; these communities, which grade into transition mire communities of unit D2.3, or into tall sedge communities of units D5.2141 or D5.2125, are best characterised in the Fennoscandian mountains, although they can be individualised in other fen systems, in particular, in upland Britain. Accompanying species include Carex aquatilis, Carex juncella, Carex rotundata, Eriophorum angustifolium, Viola epipsila, and small willows, notably Salix lapponum, Salix glauca.
