occurring in complex mosaics with lowland wet heath and valley mire vegetation, in transition mires, and on the margins of bog pools and hollows in both raised and blanket bogs. The vegetation is typically very open, usually characterised by an abundance of white beak-sedge "Rhynchospora alba", often with well-developed algal mats, the bog moss "Sphagnum denticulatum", round-leaved sundew "Drosera rotundifolia" and, in relatively base-rich sites, brown mosses such as "Drepanocladus revolvens" and "Scorpidium scorpioides". The nationally scarce species brown beak-sedge "Rhynchospora fusca" and marsh clubmoss "Lycopodiella inundata" also occur in this habitat.
