Eriophorum vaginatum
There are two main habitat types within the site; the dry dwarf-shrub heath to the north and wetter marshy grassland, wetland heath and bog-land in the low-lying basin to the south. The bog contains a variety of "Sphagnum" peat mosses - that disperse their spores from June to August - bog asphodel ("Narthecium ossifragum"), cottongrass ("Eriophorum vaginatum"), and marsh cinquefoil ("Potentilla palustris"). Other flora on the site include the climbing corydalis ("Ceratocapnos claviculata") and the royal fern ("Osmunda regalis").
