PHYTOCOENOTIC SURVEYS ON SOME MESOTROPHIC – EUTROPHIC MARSHES IN EASTERN ROMANIA

This study is a contribution to the knowledge of the vegetation of some mesotrophic - eutrophic marshes, of topogenic origin, which are located in the hilly area of Neamt county, namely: Unghi, Bahna Mare, Rascolnita, Borseni, and Bornis (Dragomiresti commune). The vascular flora of these marshes is characterized by the presence of some fairly rare plant species, into the Romanian flora, e. g.: Angelica palustris, Dactylorhiza incarnata, Ligularia sibirica, and Menyanthes trifoliata. Among the plant associations identified in the field, the next ones are rather rare in the region: ass. Caltho laetae – Ligularietum sibiricae Stefan et al. 2000, ass. Salicetum cinereae Zólyomi 1931, ass. Carici flavae – Eriophoretum latifolii Soó 1944, and so forth. The floristic and phytocoenologic richness of these marshes of Moldavia, their authenticity, their character not yet altered by the human activities, the surprising presence here of some rare relict species into the Romanian flora, are true reasons to promote all of these areas as protected ones, in the near future. Also, for the marshes of “Unghi” and “Bahna Mare”, we would like to make proposals as these to be included under the “Natura 2000” European network of protected areas.
