Erica tetralix
The wetter parts of the valley mire are characterised by an abundance of bog mosses, "Sphagnum spp", in association with species such as common cottongrass, "Eriophorum angustifolium", star sedge, "Carex echinata", and bog asphodel, "Narthecium ossifragum". The drier areas are heathland, with heather, "Calluna vulgaris", hare's-tail cottongrass, "Eriophorum vaginatum", cross-leaved heath, "Erica tetralix", and common sedge, "Carex nigra".
