Statement of the problem and goal. Vinnytsia region now demonstrates one of the lowest indicators of provision of natural protected areas and objects (2.27% of the region’s area). The regional figure for Vinnytsia is even lower, which is 1.65% of the city’s area. The need of the day is to study the localities of rare species of biota, rare biotopes, and migration routes of animals in an urbanized environment as potential objects for the development of protected areas. Materials and methods. Determination of the optimal methodology for identifying the taxonomic structure and ecological groups of the studied fauna based on the analysis of literary, cartographic, and stock materials. To assess the geocomponent representativeness of the fauna of the urban environment, expedition research methods were used. Systematization of terrestrial and terrestrial-aquatic taxonomic groups of fauna was carried out using empirical methods. Identification of characteristic traces and remains is used to record animals through visual observation. Audio Moth v.1.2.0 recording devices and an Echo Meter Touch 2 active bat detector were used to record owls (Strigiformes, Aves) and bats (Chiroptera, Mammalia). With the help of control catches, as well as through analysis of the catches of amateur fishermen, the species composition of fish was established. Results and discussion. Under conditions of significant technogenic transformation of the biotopes of the tract and nearby aquatic landscapes, a relatively rich zoocenosis has formed. This zoocenosis unites synanthropic and local species of birds, reptiles, mammals, amphibians and fish. This is facilitated by the combination of a wide range of facies that provide the trophic and topical needs of animals. The territory of the tract, thanks to the rich species composition of animals and stable interspecies connections, can effectively serve as a center for the conservation of biodiversity and an educational, ecological and aesthetic mission in an urban landscape. Scientific novelty. A specific faunal complex of the park, the mouth of the town of Tyazhilivka and the adjacent part of the Sabarovskoe reservoir has been identified. It includes 104 species of animals of the genus Chordata: class Mammals (Mammalia) - 14 species, class Birds (Aves) - 66 species, class Reptiles (Reptilia) - 4 species, class Amphibians (Amphibia) - 4 species, class Orthoptera (Actinopterygii) – 16 species. Research materials are the basis for the creation of a nature conservation area and the expansion and optimization of the existing natural reserve network of the urban environment.

Formulation of the problem. The urgency of the problem put forward is associated with the growth of anthropogenic development of the unique valley-river landscapes of the East Podolsk Transnistria is still taking place without a comprehensive geographic justification for the organization of nature management of the territory. These valley-river landscapes are unique in terms of the richness of bio- and landscape diversity. The purpose of the article is to assess the landscape and biotic diversity of the valley-river landscape of the lower reaches of the Nemiya city of the Mogilev-Podolsk-Yampolsky physical-geographical region in order to form priorities for the environmental activities of Transnistria. Materials and methods. To achieve the goal, a visual survey of the territory of the Nemia basin was carried out. The studies were carried out on the basis of: hydrological-geographical, biogeographical, botanical and zoological generalizations of the results of route observations in the Nemia River valley. Materials were used, including remote and field observations carried out in the Dniester basin. Also, data from various organizations and institutions were used (Vinnitsa Regional Department of Forestry and Hunting, Basin Water Resources Management of the city of Southern Bug, etc.). In particular, data from rural councils of settlements of the Mogilev-Podolsky urban territorial society were used. In the course of the study, such traditional methods as: statistical, literary and cartographic methods, the method of analogies, the method of comparisons and the method of generalizations were used. At the same time, such specific methods were used: a system of modeling, analysis, synthesis methods, cartographic and mathematical methods and methods of forecasting, expeditionary, continuous survey of natural areas, geophysical, identification of landscape components, etc.). Results. The study made it possible to study the ecotone of landscape and biotic diversity, including the high vulnerability of anthropogenic valley-river landscape complexes, primarily under the influence of mining and industrial developments. The features of the influence on the formation of these landscape complexes of natural and historical and social conditions were also revealed. At the same time, it was possible to establish the modern anthropogenized structure (landscape, phyto- and zoocenotic) of natural and anthropogenic landscapes within the Nemia River valley. Scientific novelty and practical significance. The conditions for the functioning of the valley-river landscape, the trends and intensity of its changes under the influence of natural and anthropogenic conditions and factors are analysed. The problems of protective belts and water protection zones are considered to assess the possibility of the Nemiya River performing the function of an eco-corridor in the projected regional ecological network. The factors influencing the ecological state of the valley-river landscape are determined. At the same time, microfoci are identified, with which successional, material-energy, transformational and destabilization changes are associated. Based on the studies carried out, proposals were made for the implementation of environmental protection measures for the Nemia River. The results of these researches can become the basis for monitoring the dynamics, development and evolution of landscapes, primarily for the formation of priorities for the environmental activities of Transnistria.

The main purpose of the research is to improve the efficiency of management decisions in the field of environmental protection through using the methods for assessing the public health risk at the current level of air pollution. Methodology. The article presents a hierarchical methodological approach for determination of the level of air pollution hazard at the state, regional and local levels. The state of atmospheric air is greatly affected by emergencies associated with accidents at chemically hazardous facilities, which result in burst releases of hazardous chemicals into the environment. When determining the environmental risk of deterioration in the state of atmospheric air, the chemical hazard indicator was taken into account. Results. On the territory of the East of Ukraine there is the largest number of potentially dangerous enterprises. A new methodology of determination of the hazard level of air pollution is presented at the existing trends of anthropogenic load and the possible occurrence of technogenic emergencies. Assessment of public health risk due to air pollution in the Mariupol city showed an extremely high level of danger. The determination of the risk as a macroecological indicator according to the new method shows a high level of hazard of air pollution in the industrial developed regions of Ukraine. The shortcomings of the methodical approach of the United States Environmental Protection Agency (EPA US), widely used in many countries of the world, are shown. An analysis of methodological approaches to assessing the public health risk has shown the promise of using the methodology for assessing potential risk in determining the level of environmental hazard of industrial enterprises. The assessment of the public health risk in the current quality state of air is given by two different methods for the regions of Ukraine with a high level of ecological and chemical hazard. The improvement of the methodology for assessing the risk to public health due to air pollution is proposed, which is presented as a scientific novelty. Currently when Ukraine has been affected by hostilities and the economic crisis, the issue of priority funding for environmental protection is very important. The implementation of the proposed methodological approach will make it possible to scientifically determine regions with an increased level of hazard to public health and minimize financial resources for improving the air quality, which has actual practical significance.
