New and noteworthy bryophyte records in Greek mountain wetlands and at woodland ecotones with notes on the phytosociological affiliation

The diversity and abundance of bryophytes in the vegetation of wetlands is significant but the habitats are understudied in the Greek mountains. This paper provides new data on bryophytes in mountain wetland habitats and at woodland edges recorded as new or reconfirmed occurrences in the administrative regions of Epirus, West Macedonia, Central Macedonia, and Central Greece. Scorpidium cossonii and Sphagnum russowii were found new to Greece. Most of the species belong to northern and high-altitude floristic elements and were encountered in moderately acidic fens, base-rich fens, flushes, nutrient-poor pools, wet meadows, mountain heaths and tall-forb vegetation. Many of the encountered species characterize Annex I habitats of the EU Habitats Directive, specifically 7230 'Alkaline fens', 7220 'Petrifying springs with tufa formation (Cratoneurion)', 7140 'Transition mires and quaking bogs', 6430 'Hydrophilous tall herb fringe communities of plains and of the montane to alpine levels', 4060 'Alpine and boreal heaths', and 3160 'Natural dystrophic lakes and ponds'.
