This site is selected as a habitat example of lowland rich fen.
This springfed wetland has formed in a shallow basin in boulder clay overlying Carboniferous limestone. The rich fen vegetation is dominated by black bog-rush Schoenus nigricans and blunt-flowered rush Juncus subnodulosus in association with a range of wetland species including grass-of-Parnassus Parnassia palustris, marsh-arrow grass Triglochin palustre and lesser club-moss Selaginella selaginoides. The nationally scarce species narrow-leaved marsh-orchid Dactylorhiza traunsteineri, fen pondweed Potamogeton coloratus and narrow-leaved marsh dandelion Taraxacum palustre occur within the fen. Mesotrophic vegetation characterised by bogbean Menyanthes trifoliata, marsh cinquefoil Potentilla palustris and bottle sedge Carex rostrata, has developed on the site of a former pool near the centre of the fen.
The site supports 7 species of dragonfly including the notable scarce blue-tailed damselfly Ischnura pumilio.
