Bazhenov Yu.A. STATUS OF THE POPULATIONS OF TARBAGAN (MARMOTA SIBIRICA RADDE, 1862) IN THE DAURIAN RESERVE AND THE FEDERAL NATURE RESERVE “DZEREN VALLEY” // Arid ecosystems. 2019. V. 25. № 2 (79). P. 64-69. | PDF
From 2010 to 2017 a field study of the location and number of tarbagan (Mongolian marmot) on the border with Mongolia and China of the TRANS-Baikal region (Russia) was conducted. The territory under consideration is part of the Federal specially protected areas: the Daurian reserve and the dzeren Valley reserve. It is shown that by 2017 the number of tarbagan in this area reached more than 2000 families. The best recovery is in those areas where the population density of tarbagan has historically been the highest (Nerchinsky ridge near the border with Mongolia). Engineering and technical facilities at the border and a special border regime favored the preservation of the original settlements of marmots. Migration of marmots from Mongolia has ceased to play an important role in maintaining the border populations of marmots on the considered section of the border of Russia and Mongolia.
