Background. Study of Bobak Marmot populations state is an important environmental and scientific problem as it is a landscape-forming species of steppe ecosystems and actively supports it. Objective of this study is to research Bobak Marmot’s present-day distribution, it’s populations state and ecological features on the territory of Samara Region.
Materials and methods. Field data on Bobak marmot’s distribution in Samara Region was collected in 2010–2012 by route-area-method of families’ accounting. During the accounting of family range the researchers used proper topographic and micro relief apartness. Accounting was performed with photo- and video equipment, navigation equipment and cartographical materials to fix study results. To clarify Bobak marmot’s present-day distribution in Samara Region different sources were used (literature sources, materials of hunting inspections for bag quota definition and other departmental information).
Results and conclusions. 107 habitats of 12 subjects of Samara Region suitable for marmots were studied. As a result 88 marmot’s colonies were found. In 19 points of research marmots weren’t found. Total number of the accounted family ranges is 2026, with total evaluative number of individuals of about 7806. Population density in colonies is high – about 43,6 individuals per km2. However with recalculation taking into account the area of habitats suitable for marmots it displays the decrease to 1,88 individuals per km2.

Key words

Bobak marmot, metapopulation, Samara Region.
