Abstract
The article presents the results of a long-term monitoring study of small mammals inhabiting the territory of the Buiratau National Park, specifically within the “Belodymovka” branch. The research was conducted across various biotopes, including steppe, meadow, mountain-forest, forest, arable land, enclosure boundaries, the Karagash tract, and shrub areas, which allowed for a comprehensive characterization of the fauna and assessment of ecological diversity. Standard trapping methods for small mammals were employed, and fieldwork was carried out from May to September 2025. The species diversity and relative abundance of rodents and lagomorphs were identified. The study determined the species composition, analyzed community structure, identified dominant species, and examined the features of their spatial distribution and habitat ranges. Seasonal and interannual dynamics of abundance were assessed, and biotopic preferences and habitat use patterns were revealed. The influence of natural and biotic factors on the formation, stability, and reproductive potential of populations was considered. Special attention was paid to the role of small mammals as indicators of the ecological state of natural ecosystems and as key components maintaining trophic relationships, soil fertility, and biocenotic balance. Comparison of current data with previous studies made it possible to identify trends in population abundance and community structure under conditions of climatic fluctuations and human activities. The presented materials have both scientific and practical significance, forming the basis for long-term ecological monitoring, assessment of ecosystem stability, and the development of effective measures for biodiversity conservation and sustainable management of natural resources within the Buiratau National Park.
