Among 288 recorded taxa (50 plant families), the most frequent representatives belong to Asteraceae (13.88%), Lamiaceae (9.37%), Poaceae (9.03%), Fahaceae (9.03%). Hemicryptophytes dominate among life forms of investigated plants (44.8%). Analysed plants belong to 29 floristic elements, and the most frequent among them are: Eurasian (19.80%), submiddleeuropean (17.71%) and subeurassian (12.85%). Considering adaptations to moisture, light, temperature, soil acidity and richness of soil in nitrogen, most of investigated plants belong to groups of submesophytes (42.36%), hemisciophytes and heliophytes (51.74%), mesothermophytes (60.76%), neutrophylous plants (61.81%) and mesotrophic (44.44%) species, respectively.
