Distribution and population size of the siberian roe deer and wild boar in the Sairam-Ugam state national nature park

Abstract

Background and Aim. Studying the population status of even-toed ungulates in specially protected natural areas is essential for the conservation of biodiversity. This article examines the distribution patterns of roe deer (Capreolus pygargus Pallas, 1771) and wild boar (Sus scrofa Sus scrofa, Linnaeus, 1758), as well as the dynamics of their population sizes in the Sairam-Ugam State National Nature Park. Analysis of their distribution patterns and population dynamics is important for the scientific substantiation of effective conservation measures for populations.
Materials and Methods. The study was conducted in 2024-2025 within the territory of the park. The study focused on populations of Siberian roe deer and wild boar inhabiting the park. In accordance with the research program, the spatial distribution patterns of these species, population assessment indicators, food resources, and population structure were determined. To identify the distribution characteristics of the Siberian roe deer in the Sairam-Ugam State National Nature Park, field observations were
supplemented by the results of specially designed questionnaires distributed among foresters and hunting management specialists.
Results. Observations revealed differences in the biotopic distribution of males and females. The survey results also demonstrated inter-branch differences in the sex and age structure of the Siberian roe deer and wild boar populations. It was established that these differences were associated with the spatial heterogeneity of habitats within the park, as well as with patterns in the distribution of food resources.
Conclusion. The results obtained allow for a deeper understanding of the ecological characteristics of Siberian roe deer and wild boar populations within the Sairam-Ugam State National Natural Park and provide an important scientific basis for the conservation of these species, their sustainable use, monitoring, and the development of management strategies. Furthermore, the findings contribute to the improvement of conservation measures aimed at reducing anthropogenic pressure and preserving key habitats.
