Biotopes of the «Romanivka Mire» Botanical Nature Sanctuary of the National Importance

The classification of the biotopes of the «Romanivka mire» nature sanctuary, including 5 types of biotopes of a higher hierarchic level (C, D, E, G, and I) and 15 types of biotopes of a lower hierarchic level, is given in the paper. The largest territories are occupied by the biotopes of the D (50-60%) and G (about 30-40%) types. The characteristics of biotopes include the list of associations, species number in each biotope and rare species, soils, humidification mode, climate peculiarities, and watercourse regulation. The factors exerting an adverse effect on the spread of typical sedge communities were revealed. Thus, constant monitoring of this nature sanctuary will ensure valuable communities and species conservation.
