54.61 - Nemoral bare peat communities

Classification des habitats du Paléarctique (2001)

Description

Highly constant pioneer communities of humid exposed peat or, sometimes, sand, of nemoral Atlantic and sub-Atlantic regions of the Palaearctic domaine, with Rhynchospora alba, Rhynchospora fusca, Drosera intermedia, Drosera rotundifolia, Lycopodiella inundata, forming on stripped areas of blanket bogs or raised bogs, but also 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. These communities are similar, and closely related, to those of shallow bog hollows (unit 51.122) and of transition mires (unit 54.57). They are often associated with wet heaths of unit 31.1 or Myrica gale scrubs of unit 44.93.
