Vegetation

This a very diverse mire community usually dominated by the slender leaves of Carex lasiocarpa and the broad green leaves of Menyanthes trifoliata. Other constant features are Equisetum fluviatile, the forbs Succisa pratensis, Potentilla palustris, Filipendula ulmaria and Angelica sylvestris, and the trailing stems of Vaccinium oxycoccosCarex limosa and the rather rare, tussock-forming Carex appropinquata are frequent here, as is some patchy cover of Salix repens. There is usually a well-developed bryophyte layer in which Calliergonella cuspidata and Calliergon giganteum are the most frequent plants, but the calcicole ‘brown mosses’ Campylium stellatum, Drepanocladus cossonii/revolvens, Bryum pseudotriquetrum or Scorpidium scorpioides are often encountered.

 

Ecology

This is a wetland community of nutrient-poor, relatively neutral situations. Most records come from the quaking fen scraw of Scragh Bog.

 

Sub-communities

No sub-communities are currently described.

 

Similar communities

Carex lasiocarpa is frequent in the FE2B Carex limosa – Menyanthes trifoliata mire, but that often-flushed community typically lacks Vaccinium oxycoccos, instead supporting several different constant species in Phragmites australis, Potamogeton polygonifolius, Ranunculus flammula and Hydrocotyle vulgaris. Vaccinium oxycoccos also occurs in the BG2A Eriophorum vaginatum – Vaccinium oxycoccos bog but that is a far more acidic community of ombrotrophic raised bogs.

 

Conservation value

This is a species-rich community. Examples may correspond with EU HD Annex I habitat 7140 Transition mires. Hamatocaulis vernicosus, an EU HD Annex II moss species is known from this community.

 

Management

Typically, this is an unmanaged community. The main threats include drainage, reclamation, ground water pollution and peat extraction.
