Forest fires are increasingly becoming the cause of the destruction of a particular ecosystem or landscape, the restoration of which takes quite a long time. Research on pyrogenic succession is one of the urgent tasks in modern science. In the course of this work, an analysis of vegetation restoration on the territory of the Barguzin Nature Reserve was carried out. After a grass-roots fire on the ecological trails of the Shumilikha River valley and on the Davshinsky pillars, the course of pyrogenic succession was monitored from 2016 to 2019. The study of the progress of vegetation restoration was carried out on the laid test sites on each of the trails. In the course of the work, geobotanical descriptions were made, an abundance of species diversity was revealed, and the total projective cover was also taken into account. In the first year after the fire, such species as Chamerion angustifolium L., Calamagrostis korotkyi L., Bergenia crassifolia (L.) Fritsch., Calamagrostis obtusata Trin., etc. were found on trial sites. During the first three years of succession, it was revealed that the species composition and wealth were not constant and changed every year. At the same time, there was an increase in the projective coverage during the first three years (from 10 to 30% in the valley of the Shumilikha River, from 15 to 45% on the Davshinsky pillars). An increase in the total projective coverage in the studied areas indicates a general restoration of the landscape.
