Species composition variability of the thirteen plant communities identified. NMDS based on Hellinger-transformed vegetation cover dissimilarities (Bray-Curtis distance) between 2017–2019. Left panel: Example of variation in plant composition of three plant communities present at 149+270 bofedal. Number indicates the same sampling location. Right panel: Variability of species composition across years. Filled symbols represent plant communities significantly different from each other. Plant communities: 1: Distichia muscoides, 2: Rockhausenia pygmaea, 3: Plantago rigida, 4: Plantago tubulosa, 5: Lachemilla diplophylla, 6: Aciachne pulvinata, 7: Juncus stipulatus, 8: Calamagrostis rigescens, 9: Calamagrostis chrysantha, 10: Distichia filamentosa, 11: Lobelia oligophylla, 12: Mixed community 1, 13: Mixed community 2.
