Annex I habitats that are a primary reason for selection of this site

  • This lowland valley mire contains one of the largest surviving examples of alkaline fen vegetation in central England, a region where fen vegetation is rare. The M13 Schoenus nigricansJuncus subnodulosus vegetation found here occurs under a wide range of hydrological conditions, with frequent bottle sedge Carex rostrata, grass-of-Parnassus Parnassia palustris, common butterwort Pinguicula vulgaris and marsh helleborine Epipactis palustris. The alkaline fen vegetation forms transitions to other vegetation types that are similar to M24 Molinia caeruleaCirsium dissectum fen-meadow and S25 Phragmites australisEupatorium cannabinum tall-herb fen and wet alder Alnus spp. wood.
