Abstract
Two new associations of wet woodlands with Picea abies from the Western Carpathians are described. Stands of the first unit, Leucobryo glauci-Piceetum abietis, are located on dryer margins of mires, on plains where water from snow melting and rains remains considerable long above the soil surface. The most characteristic sign of the species-poor flora of this forest plant community is the dominance of moss Leucobryum glaucum accompanied by constant presence of Sphagnum spp. Two subassociations are distinguished in respect of the ecological differences. The second described plant community, association Stellario nemorum-Abietetum albae, occupies quite different habitat of spring areas and other more wet localities. Abies alba plays an important role in the canopy, field layer is characterised by constant presence of Stellaria nemorum, Equisetum sylvaticum, Oxalis acetosella, Senecio ovatus, Chaerophyllum hirsutum, Lysimachia nemorum and other species. Three subassociations and five variants are distinguished.
Highlights
Wet woodlands with Norway spruce are one of the groups of water-determined forest plant communities
Natural occurrence of Picea abies in these azonal woodlands is preserved by soil conditions which are determined by high level of ground-water causing reduced vitality of other tree species: it is an extragradal natural occurrence of Picea abies, outside of the main natural species distribution which lies in the supramontane belt in the Western Carpathians (Kučera 2012)
The overall syntaxonomical evaluation of wet woodlands with Picea abies of the Western Carpathians is prepared within another study (Kučera 2019 in red.)
