Coenoses are often flooded, regularly, soil being well soaked with water so that it remains wet throughout the year. Due to the dominance of Scirpus sylvaticus populations (Table 1), floristic diversity remains reduced, so that their phytosociological characterization is often difficult. Besides the edifying species, species of Molinio-Arrhenatheretea class are also found: Juncus inflexus, Equisetum palustre, Lychnis flos-cuculi, Lythrum salicaria etc. Association is frequently met in the studied area, at altitudes between 430—580 m. The phytocoenoses of this association, while showing no economic importance, they fructify make the most of a swampy ecotope unsuitable for other useful vegetation formations, having a role in maintaining the ecological balance.
