Concept: Rich fens, including eutrophic tall-herb fens and calcareous flushes and soaks in the eunishabitats vocabulary

Concept URI http://eunis.eea.europa.eu/eunishabitats/D4.1
Preferred label Rich fens, including eutrophic tall-herb fens and calcareous flushes and soaks
Definition Wetlands and spring-mires, seasonally or permanently waterlogged, with a soligenous or topogenous base-rich, often calcareous water supply. Peat formation, when it occurs, depends on a permanently high watertable. Rich fens may be dominated by small or larger graminoids ([Carex] spp., [Eleocharis] spp., [Juncus] spp., [Molinia caerulea], [Phragmites australis], [Schoenus] spp., [Sesleria] spp.) or tall herbs (e.g. [Eupatorium cannabinum]). Where the water is base-rich but nutrient-poor, small sedges usually dominate the mire vegetation, together with a "brown moss" carpet. Hard-water spring mires (D4.1N) often contain tufa cones and other tufa deposits. Excluded is the water body of hard-water springs (C2.1); calcareous flushes of the alpine zone are a separate category (D4.2). Rich fens are exceptionally endowed with spectacular, specialised, strictly restricted species. They are among the habitats that have undergone the most serious decline. They are essentially extinct in several regions and gravely endangered in much of central and western Europe.
