The diversity of mesic and wet grasslands for the north part of the steppe zone in the Southern Bug River basin is characterized by the example of Buzkyi Gard National Nature Park and adjacent territories. I classified 39 vegetation relevés with quantitative classification methods (JUICE, TWINSPAN modified algorithm) and obtained seven clusters, which represent three associations, three communities and one derivate community within six alliances (Agrostion vinealis, Althaeion officinalis, Arrhenatherion elatioris, Convolvulo arvensis-Agropyrion repentis, Potentillion anserinae, Veronico longifoliae-Lysimachion vulgaris). Using Canonical Correspondence Analysis (CCA), Detrended Correspondence Analysis (DCA) and Didukh’s ecological scales, I determined the main environmental factors, which explain differentiation of the resulted vegetation units: variability of damping, salt regime of a soil, soil moisture, soil aeration, carbonate content in a soil, light. Characterized vegetation corresponds to six habitat types of the EUNIS classification (R21, R22, R35, R36, R55, V38). I also reviewed the major factors of negative impact on the meadow vegetation of the territory, in particular the changes of traditional land use in the last decades and their consequences. The main measures of management for studied communities should be mowing, moderate grazing, and removal of tree and shrub species if necessary.

Primary field floristic studies of synanthropic species with a high invasive capacity are an important basis for broad, generalizing analyzes of the problems of flora transformation of ecotopes of different levels of anthropogenic transformation. Acroptilon repens is one of the species that has a high invasive capacity and is a quarantine plant on the territory of Ukraine. The aim of the work was to identify the localities of Acroptilon repens in the in the interfluve of the lower Dnister–Tiligul rivers, to characterize the conditions for the growth of plants of this species. Acroptilon repens is a herbaceous perennial plant, a xerophyte and a heliophyte; comes from Central and Asia Minor. It reproduces well both generatively and vegetatively (by root sprouts). According to the degree of naturalization, it is an epecophyte, according to the chronotype, it is a kenophyte. According to the method of spreading, the seeds are anemochorous. It is able to grow in areas with a wide range of environmental conditions and different levels of anthropogenic transformation (from natural to fully transformed). Preventive, agrotechnical, chemical, biological control measures are used to combat this species. Ecotopes with different levels of ecotope transformation were examined. According to herbarium materials of the herbarium (MSUD) of Odesa National University named after I.I. Mechnikov the species had not previously been noted in the Odesa region. The author found four localities of Acroptilon. Three of them are on transformed sections of transport routes: the village of Avangard, on the side of the Odesa — Reni Road and in the vicinity of S. Yehorivka. These are sections of highways and abandoned railway tracks. Another one is on a natural steppe slope. On the transformed areas, the participation of other plant species in the «spots» with steppe mustard is small: up to four species. In the natural area (in the vicinity of the village of Kholodna Balka), a total of 44 species coexisted with steppe mustard. Among them, only 23 (or 52.27%) species are synanthropic and only three (Bromus squarrosus, Descurainia sophia, Sisymbrium loeselii) are invasive species. They are mainly represented by a small number of specimens, but among them there are two species of local protection level: Kohlrauschia prolifera, Ephedra distachya. In the spring, in the «contour of the spot» with Acroptilon repens, the following plants of state protection level were found: Gymnospermium odessanum, Crocus reticulatus. These plants are ephemerals, and the terms of their growth and the beginning of vegetation of Acroptilon repens do not coincide.

The currency of evolution of researching alien flora from the beginning of its systematic studies to our time is analyzed. It is stressed on some regularities of its development. Six stages of development of investigations of the marked fraction of the flora and phytoinvasions are separated. It is marked that on the first stage which lasted from the beginning of the XX-th century to the end of the World War I, theoretical fundamentals of studying alien flora are created with the same-time providing a couple of regional researches. The most famous researchers of this period whose works made an influence to further development of the alien flora investigations are M. Rikli and A. Thellung. On the second stage (between two world wars) relatively not numerous studies mostly on the macroregional level are realized. The works by M.I. Kotov dedicated to the alien flora of № 1, 2023 BULLETIN OF UMAN NATIONAL UNIVERSITY OF HORTICULTURE ECOLOGYUkraine played an outstanding role on this stage of researches. The third stage (the second half of 1940-th -50-th years) was characterized by growing of quantity of the investigations and deeping their theoretical fundamentals. The works by W. Kreh that had a theoretical and methodological context were the most significant on this stage. The fourth stage (60-th years) was signed by creating developed classifications of invasive species. The most perfect throw them was a classification created by J. Kornaś that didn't lose its significance to today. The main contents of the fifth stage (70-90-th years) was appearance of numerous publications of the results of investigations on the meso-and microregional levels. An outstanding place throw them occupies the investigation of Ukrainian scholar V.V. Protopopova that fully characterized the alien flora of the bigger part of the territory of Ukraine and perfected the classification of invasive species by J. Kornaś. On the sixth, current, stage, from the one side, regional studies of phytoinvasions are actively lasting; from the other side, the theoretical base of studying alien flora is optimizing. Especially, the conclusive works of Ukrainian researchers S.L. Mosyakin and M.V. Shevera and foreign scientists M. Davis and C. Thompson dedicated to issues of terminology of invasive floristics have an important significance. As a perspective direction of next investigations may be studying phytoinvasions on the level of regions of Ukraine and also enforcing emphasis on researching geographical aspects of alien flora distribution.
