Lawns and hummock-to-hollow transition communities of Palaearctic bogs dominated by Sphagnum papillosum associated with Eriophorum vaginatum, most characteristic of maritime and submaritime regions of the western and eastern Palaearctic, often constituting the dominant lawn community in Atlantic and sub-Atlantic bogs of nemoral Europe. Erica tetralix is a usual member of the community in western regions; when its cover exceeds that of Eriophorum vaginatum the stands should be listed under unit D1.1115. In boreal Europe Sphagnum papillosum carpets are more characteristic of minerotrophic acidic fens than of bogs.
