Biodiversity centers of fauna in the urbanized landscape of Eastern Podillia: taxonomic richness and conservation prospects

Abstract

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.
