Transition mires and quaking bogs

English name: Transition mires and quaking bogs

Description (English)

Incompletely terrestrialized wetlands occupied by peat-forming vegetation with acid groundwater or (for vegetation rafts) acid underlying pool or lake water. Characteristic species are Calla palustris, Carex chordorrhiza, Carex diandra, Carex heleonastes, Carex lasiocarpa, Carex limosa, Carex rostrata, Menyanthes trifoliata, Potentilla palustris, Rhynchospora alba, Scheuchzeria palustris. Included are rafts of Sphagnum and Eriophorum (D2.38) and quaking rafts of Molinia caerulea (D2.3D). Excluded are stands of vegetation fringing water bodies (C3.2) unless the vegetation raft is sufficiently extensive to count as a habitat in its own right.
