Abstract
Steppe ecosystems in Ukraine are currently fragmented, largely transformed by anthropogenic activities and characterized by violations of the use regime in the territories of nature reserves, which makes the protection and conservation of steppe biodiversity, in particular, plant species that form a unique steppe phytocoenosis, an important area of research. Legumes play an important role in meadow-steppe phytocenoses, ensuring their stability, productivity and biodiversity. Population studies make it possible to assess the status and structure of populations of typical steppe species and, based on the results, to develop an action plan for their protection and reproduction. The article presents the results of the vitality analysis of six populations of Trifolium medium L. and three populations of Trifolium montanum L. growing in the conditions of meadow-steppe phytocenoses of the Nature Reserve “Mykhailivska Tsilyna”. The vitality analysis was carried out according to the generally accepted method by Yu.A. Zlobin. During the vitality analysis, it was found that, according to the vitality type, among the six populations of T. medium, four belonged to depressed (Q index values ranged from 0.0435 to 0.1250) and two populations were balanced (Q index values ranged from 0.2500 to 0.3250). None of the six populations of T. medium belonged to the prosperous ones. Among the three populations of T. montanum, two were depressed by vital rate (Q index values ranged from 0.0625 to 0.0938), and one population was balanced (Q index value was 0.3126). No populations of this species of prosperous type were found. The dependence between the mode of territory use and the quality index of T. medium and T. montanum populations was established. It was noted that populations under the haying regime had a higher quality index compared to populations growing in areas without haying, where populations had a significant proportion of individuals of the lower vitality class (c) and a lower quality index. The absence of populations of the thriving type indicates a deviation from the optimal growth conditions of the studied species on the territory of the Nature Reserve “Mykhailivska Tsilyna”. As part of the effective management of protected steppe areas, haymaking can contribute to the conservation of certain plant species, including legumes. At the same time, this process should be balanced, scientifically grounded and implemented, taking into account the specifics of a particular territory and its species diversity.
