Viola palustris; Drosera rotundifolia; Dianthus deltoides; Alsine tenuifolia; Radiola millegrana; Hypericum elodes; Comarum palustre; Parnassia palustris; Helosciadium inundatum; Hydrocotyle vulgaris; Carduus pratensis; Vaccinium Oxycoccus; Menyanthes trifoliata; Pedicularis palustris; Scutellaria minor; Anagallis tenella; Centunculus minimus; Narthecium ossifragum; Rhyncospora alba; Eriophorum vaginatum; Triodia decumbens; Molinia cærulea; Nephrodium Oreopteris; Osmunda regalis; Lycopodium Selago; Equisetum hyemale.

Surface strata; Water stones, Bunter soft red sandstone and Pebble bed, Permian breccia, Permian clays and sandstones, Coal measures, Silurian and Cambrian rocks of the lower Lickey.
