Classification des habitats CORINE biotopes

Descriptif officiel

Diverse, often extensive, fen communities, with Carex davalliana, C. hostiana, C. lepidocarpa, C. capillaris, C. panicea, C. nigra, C. demissa, C. flava, C. pulicaris, Eriophorum latifolium, Blysmus compressus, Schoenus ferrugineus, Eleocharis quinqueflora, Juncus articulatus, Scirpus cespitosus, Molinia caerulea, Dactylorhiza traunsteineri, Tofieldia calyculata, Allium schoenoprasum, Potentilla erecta, Swertia perennis, Primula farinosa, Parnassia palustris, Pinguicula vulgaris and a moss layer formed by Drepanocladus intermedius, Cratoneuron glaucum, Campylium stellatum, mostly characteristic of Alpine and peri-Alpine regions, with outlyers in the Hercynian system. This extremely species-rich community is still represented by a few large, very well preserved examples on the Bavarian plateau. These are a refuge for many rare species, including the relict, threatened Pedicularis sceptrum-carolinum and the orchids Dactylorhiza traunsteineri, D. ochroleuca, D. incarnata, Herminium monorchis, Epipactis palustris. Elsewhere in their range, the Davall sedge fens have undergone a drastic reduction, leading to extinction in many areas.
