abstract

The article analyses survey data of small mammals collected by the method of live trapping on two trap lines, the dynamics of beaver numbers in one of the colonies, and random encounters of roadkill mammals in the Homilshanski Lisy National Nature Park and nearby areas. The data were collected in 2015–2022 during field research. Small mammals were studied on the second, pine barren terrace of the Siverskyi Donets River. Two trap lines (trapping trenches with five traps in each, made of two-litre PET bottles) were laid in the pine forest. The first was in an undamaged area of the forest, and the second was in an area damaged by a grassland fire in 2005 and currently undergoing natural forest ecosystem restoration. A total of six species of small mammals were recorded during the survey period, including Sylvaemus uralensis, Myodes glareolus, Sylvaemus tauricus, Mus musculus, Sorex araneus, Crocidura suaveolens, as well as an unidentified Sylvaemus sp. The research has shown that, during the years of peak numbers, not only the abundance of individual species increases, but also the number of recorded species. The beaver colony, where the surveys were conducted, is located in a floodplain on the left bank of the Siverskyi Donets River in a system of three small lakes interconnected by channels. There are also seasonal peaks in the numbers of roadkill species. In total, 17 species have been recorded dead on the roads, which is almost a third of all mammalian species of the Homilshanski Lisy National Nature Park (as of 2020, 60 species have been registered in the Park). It was found that there is a positive correlation between population increase in different groups of mammals and the frequency of deaths of different groups of mammals and the number of species killed on roads. We identified the places where certain anthropogenic factors (poaching, road repairs) are superimposed on natural phenomena and how this affects the state of fauna protection in the National Nature Park. In general, the population dynamics of mammals over the years correlates with the dynamics of encounters of roadkill birds, reptiles, and amphibians, which we also studied during this period. We have proposed a number of recommendations for developing a strategy for the protection of various species in the National Nature Park and its protected area: measures to reduce the risk of animal death on highways.
