RESEARCH AND ANALYSIS OF THE COMPOSITION HERBAL CREATION OF PHYTOCENSOSIS M. VINNYTSYA BY EXAMPLE OF INDIVIDUAL PARTS OF FOREST PARK AND BOTANICAL GARDEN VNAU

Since herbaceous vegetation is one of the most plastic elements of the forest and the first one responds to changes in the natural environment, we decided to detect changes in the structure and dynamics of the grass cover of forest ecosystems under conditions of complex anthropogenic impact on the example of the botanical garden «Podillya» and the forest park in the city Vinnytsia. In the course of the research, we found that at the accounting registration area number 1 the largest coverage is observed 12.04 and is 35%, and the lowest 18.06 – 10%. At the registration area number 2, the total coverage on 12.04 amounted to 40%, and as of 18.06 – 60%, that is, there is an increase in plants at the site, which indicates a low level in plant plutonium within the area. At the registration area 5, we found that the total projective coverage of 09.04 was 35%, 14.05 was a favorable period for these plant groups and was the largest (50%), and 17.06 phytocenoses went down and amounted to 20%. This process is associated with an increase in the vititopivity of living aboveground cover, due to an increase in the number of visitors and low throughput of individual sections of the botanical garden VNAU. We found that forest ecosystems undergo transformation of grass cover in grass-ruderal xerophytic groups due to the influence of a complex of negative biotic and abiotic factors – anthropogenic violation of forest vegetation conditions, planting weakening, recreational and man-made liquefaction of tree tents, heliophilization and xerophytization of forest conditions, which leads to reralization, adventitia of the grass cover. Anthropogenic changes in ecological regimes determine the domination of species that are more tolerant to transformed forest-based conditions.
