Abstract
This article presents the results of a research study into the dynamics of mammal populations in the Nizhnesvirsky Nature Reserve during the 2014–2024 period. The research was conducted using the authors’ field observations and archival data. The influence of a number of factors, i.e., snow cover depth and spruce and pine cone yield, on the mammal populations in the area under study is analyzed. A weak snow cover was shown to be favorable for maintaining high numbers of wild boar populations, while a thicker show cover was more favorable for predators (wolves). The weather conditions favorable for harvest of spruce and pine cones was found to have a positive effect on both herbivores and predators. In the dynamics of relationships between predators and their prey, regular interrelated fluctuations in population numbers are observed.
