54.2C - Bottle sedge alkaline fens

Classification des habitats du Paléarctique (2001)

Description

Alkaline fen communities of the Palaearctic domaine 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 54.5, or into tall sedge communities of units 53.2141 or 53.2125, are best characterized in the Fennoscandian mountains, although they can be individualized in other fen systems, in particular, in upland Britain. Accompanying species include Carex aquatilis, Carex juncella, Carex rotundata, Eriophorum angustifolia, Viola epipsila, and small willows, notably Salix lapponum, Salix glauca.
