Description
Spring mires of calcareous, often petrifying, springs. Their specialised communities, usually dominated by bryophytes, belong to the Cratoneurion commutati. Characteristic species are the mosses Cratoneuron filicinum, Cratoneuron commutatum, Cratoneuron commutatum var. falcatum, Catoscopium nigritum, Eucladium verticillatum, Gymnostomum recurvirostrae, with Equisetum telmateia, Equisetum variegatum and flowering plants including Cochlearia pyrenaica, Arabis soyeri, Pinguicula vulgaris, Saxifraga aizoides. The associated swamp communities belong to the Caricetalia davallianae, see units D4.13-D4.15. Large petrifying springs form tufa cones that constitute singular habitats with several interacting plant and animal communities, which are described as subunits.
