Assessment of changes in the structure of the forest ecosystems for example sanitary woody plantations in the Steppe Dnipro

Abstract The main acceleration of climatic changes is considered to be the main consequences of existing anthropogenic influences and transformations in the wood ecosystems of the Steppe Dnipro industrial areas. Now, the preparation of science-based programs for the restoration and development of artificial tree plantations, which can increase the stability and diversity of forest ecosystems in the steppe zone under these conditions, is very important. However, artificial tree and shrub plantations are formed according to certain natural laws. It is necessary and urgent to study the current state of phytodiversity to ensure the effective protection of biodiversity, and implement nature conservation management on this basis, including the expansion of the areas of nature reserves. The purpose of this research work was to assess changes in the structure of the Dnipro Steppe woody ecosystems using the example of dust-protection and water-protection sanitary plantations. Modern biodiversity, formed in the natural ecotopes of the Steppe Dnipro region of Ukraine, is quite specific, primarily due to the combination of natural and anthropogenic landscapes in these territories. Depending on the ecological location territory conditions, taking into account the vitality indicators of the plantations, the further development of woody ecosystems according to the vectors of progress or regression is possible. Hence, there is an urgent need to study the biometric indicators of the Kryvyi Rih district’s woody ecosystems under different growth conditions. The work carried out will become the basis for the development of the main directions of preservation and reproduction of phytodiversity in the woody ecosystems of the territory, which will make it possible to plan the necessary vectors for the protection and restoration of biological diversity of artificial trees and shrub plantations of the Kryvyi Rih districts. identifying the features of local guarantee of rare species from various protection lists. It will also contribute to the provision of ecosystem services by natural, spontaneous and artificial woody plantations of the Middle Dnipro region. The received recommendations form the basis of complex measures to preserve and restore the stable state of artificial tree plantations of the Kryvyi Rih district, located on the steep slopes of mine dumps and rafter-beam systems near the rivers and water reservoirs of the Dnipro Steppe.
