7140 Transition mires and quaking bogs
Turmennan is one of the best examples in Northern Ireland of a transition mire. The edaphic conditions are influenced by the position of the groundwater table in the surface peat layer, which is partly related to the extent of past peat-cutting over the site. The main plant community of the mire surface is formed by an extensive mixed sedge sward dominated by bottle sedge Carex rostrata and including species such as common sedge C. nigra, star sedge C. echinata, ragged-robin Lychnis flos-cuculi, marsh pennywort Hydrocotyle vulgaris and water horsetail Equisetum fluviatile. These species grow over a carpet of brown mosses dominated by Calliergon cuspidatum and C. cordifolium. In places where the water is more acidic, bog-mosses such as Sphagnum squarrosum and S. subnitens replace the brown mosses. Much of the central area of the site is dominated by common reed Phragmites australis. Other, more localised fen communities include a mixed sedge sward dominated by lesser tussock-sedge Carex diandra, floating mats of bogbean Menyanthes trifoliata and ‘soakways’ with the notable marsh St John’s-wort Hypericum elodes prominent.
