Tundra communities are widespread in the northern part of Russia, in particular on the Yamal Peninsula in the registration of Siberia, where research was carried out. For the study, we used plants of the species Betula nana and Salix lanata, these species are among the most common in the southern tundra of Yamal. Sampling sites were located on various morphological elements of the relief with the identification of patterns in the distribution of natural resources that determine the radial growth of the trunks of Betula nana and Salix lanata. At each site, at least 30 samples of each species were taken to obtain a sufficient sample. The sampling sites were located on different morpholog-ical parts of the relief. In the course of the study, general growth trends are highlighted, as well as absolute values of growth for 5 years. This age corresponds to the minimum age of the selected plants. As a result, data were obtained on the distribution and growth characteristics of Betula nana and Salix lanata shrubs along the relief profile; the most and least favourable areas of the profile for the growth of shrubs were identified. To compare the general trends of radial growth, a faster slowdown in growth was found in Betula nana. In addition, it was found that the species Salix lanata has a stronger effect on mechanical impact (winter road).
