The purpose of the study is to reveal the influence of European bison (Bison bonasus) on flora and vegetation change in Krasnikovsky forestry of “Orlovskoe Polesie” national park. In August-September of 2019, floristic and geobotanical studies of flora and vegetation were carried out at self-feeding stations, in the locations of salt licks, as well as in the bisons’ passage points in Krasnikovsky forestry of “Orlovskoe Polesie” national park. There were identified 142 species of vascular plants of 9 phytocenotic formations according to G. Zozulin’s classification: nemoral, birch forest, helobious grass, alder, boreal-willow, boreal forest, pine forest, meadow and anthropogenic. The number of phytocenotic groups and the percentage of species in each of them varied. A direct relationship was established between the time of self-feeding stations formation and the participation of non-forest species in the corresponding phytocenoses: the earlier self-feeding station was formed, the higher the participation percentage in the coen of non-forest species. When assessing geobotanical descriptions according to the Ramensky’s pasture digression ecological scale it was revealed that the greatest digression degree is observed in the locations of self-feeding stations: from a moderate influence of grazing (semi-pasture stage, 5 points) to a weak influence of grazing (hay stage, 4.5 points). In places adjacent to feeding self-feeding stations, or bisons’ passages, a weak influence of grazing was noted, a haying stage (3.7-4.0 points). In the places solonetzic soil locations, the influence of grazing does not affect (2 points) or there is a weak influence of grazing, haying stage (3-4 points).
