Gafta and Mountford [18], describe the habitat 7220* as found around springs with hard (high conductivity) water and active travertine or calcareous tufa formation; sites are generally small (point or linear formations) and dominated by bryophytes (Cratoneurion commutati). This European habitat includes two Romanian habitats (R5417 and R5419) [16]. The vegetation associations within the habitat include: Cratoneuretum filicino-commutati (Kuhn 1937) Oberd. 1977 (syn.: as. Cratoneuron commutatum Puscaru et al. 1967); Cochleario pyrenaicae-Cratoneuretum commutati (Oberd. 1957) Th. Müller 1961 (syn.: Carici flavae-Cratoneuretum cochlearietosum pyrenaicae $tefureac 1972); Doronico carpatici-Saxifragetum aizoidis Coidea (1986) 1990. Corresponding to the description format within the EU27 interpretation manual [2], the plant species present are: Arabis soyeri, Cochlearia borzaeana (i.e. C. pyrenaica) on areas rich in heavy metals, Pinguicula vulgaris, Saxifraga aizoides, Carex appropinquata and Juncus triglumis. Bryophyte species include: Catoscopium nigritum, Cratoneuron commutatum, C. commutatum vat. falcatum, C. filicinum, Eucladium verticillatum, Gymnostomum recurvirostrum, Drepanocladus vernicosus, Philonotis calcarea, Drepanocladus revolvens, D. cossonii, Cratoneuron decipiens and Bryum pseudotriquetrum.

A particularly relevant source of information on habitat 7220* is found in the “Habitat 7220 Fact Sheet for Natura 2000 in Romania” [15], covering Romanian habitats R5417 and R5419 [16]. The author describes the habitat as hydro-hygrophilous, developing on calcareous substrates comprising basophilous plant communities, poor in species and dominated by bryophytes from the generas Cratoneuron and Philonotis. The water of these springs is rich in bases, often form calcareous tufa due to calcium sedimentation.

Characteristic and dominant species of the Natura 2000 habitat 7220*: Silene pusilla, Saxifraga aizoides, Cochlearia pyrenaica ssp. borzeana, Pinguicula vulgaris, Doronicum carpaticum, Chrysosplenium alpinum, Cratoneuron commutatum, Cratoneuron filicinum, Philonotis calcarea, Bryum pseudotriquetrum and Calliergonella cuspidate [18].

For each of R5417 and R5419 Romanian habitats both of which with very limited occurrence in Romania, are describes the correspondence to other classifications, component plant associations and their habitat structure [16].
