D2.39 - Niveau 4 : Radeaux de Menyanthes trifoliata et de Potentilla palustris
Description
Transition mire communities of the Palaearctic domaine constituted by the association of forbs, in particular Menyanthes trifoliata, Potentilla palustris (Comarum palustre), Hydrocotyle vulgaris, Cicuta virosa, and sphagna or brown mosses, often in floating carpets, occupying wet areas in mire systems or the terrestrialisation zone at the edge of watercourses and waterbodies. The community is clearly structured into three layers. Potentilla palustris (Comarum palustre) dominates in the highest one, the second layer is dominated by Carex rostrata and Menyanthes trifoliata, and the third layer is composed of Sphagnum spp.
