White beak-sedge and mud bottom communities
Sparse, bryophyte-poor, sedge and rush communities of bare, extremely wet peat muds of boreal Palaearctic mires, frequently inundated, remaining wet for a prolonged part of dry periods, together with pioneer communities of humid exposed peat or, sometimes, sand, forming on stripped areas of blanket bogs or raised bogs, as well as on naturally seep- or frost-eroded areas of wet heaths and bogs, in flushes and in the fluctuation zone of oligotrophic pools with sandy, slightly peaty substratum.
