Fen communities of calcareous wet dune slacks of northern France and Belgium formed by Carex trinervis, Carex scandinavica, Juncus anceps, Juncus subnodulosus, Parnassia palustris, Gentianella amarella, Herminium monorchis, Drepanocladus aduncus, Campylium stellatum, without, or with little, Schoenus nigricans. These communities, limited to dunal systems and for which this code will thus be used in conjunction with those of unit 16.33, are gravely threatened.
