Phytosociological relevés of Juncetum subnodulosii wet meadows in northern Poland (1973–1983)

The data originate from field surveys conducted between 1973 and 1983 and represent historical vegetation records from fen and wet meadow habitats. The dataset consists of seven phytosociological relevés, each documenting the complete species composition of vascular plants recorded within homogeneous vegetation plots.

Species abundance was estimated using the Braun–Blanquet cover-abundance scale. The dataset is published in a standardized format compatible with GBIF and includes both relevé-level data (sampling-event information) and species occurrence records derived from phytosociological tables.
