Download full pdf synopsis: FE2E
The chief feature of this mire assemblage is an abundant carpet of Sphagnum recurvum agg. Through this layer typically grow some Menyanthes trifoliata and Carex rostrata. Frequently, these are attended by Eriophorum angustifolium or Potentilla palustris. There is a whole suite of occasional graminoids, comprising Anthoxanthum odoratum, Holcus lanatus, Juncus effusus, Carex echinata, Agrostis spp., Carex nigra and Molinia caerulea. Sphagnum palustre is the most likely other Sphagnum to be found and occasionally there is some cover of Aulacomnium palustre and Polytrichum commune.
This is a flush community of nutrient-poor, strongly acidic situations. Most records come from the soak systems of Clara Bog or other bogland.
No sub-communities are currently described.
From the other communities in FE2 Menyanthes trifoliata – Potentilla palustris group, the current community is distinct due to its abundant cover of Sphagnum. The FW3Cii Carex rostrata swamp/fen Sphagnum cuspidatum – Warnstorfia fluitans sub-community may be similar at first glance, but there is a difference in the dominant Sphagnum spp. and Menyanthes trifoliata is typically absent in FW3Cii.
Examples of this community may correspond with EU HD Annex I habitat 7140 Transition mires.
Typically, this is an unmanaged community. The main threats include drainage, reclamation, ground water pollution and peat extraction.
