The distribution of Viscum album L. in the Bryansk region has been studied. The distribution assessment was performed on a grid basis. In the 20th century, mistletoe was noted in 8 cells, and at present the species has been registered in 95 cells out of 378 squares of grid mapping. Recently, the species range in the region has significantly expanded in the north-eastern direction. Most often, mistletoe was noted in the central, southern and south-eastern regions of the Bryansk region, in the south-western regions on the border with Belarus in the 21st century the species was not found; finds north of Bryansk in the region have not been found. In the Bryansk region, mistletoe has been noted on 29 species of woody plants, most often in natural habitats it is recorded on Betula pendula. Within the boundaries of populated areas, V. album is most often found on Betula pendula, Sorbus aucuparia, Acer platanoides, Populus tremula, Pyrus communis, Prunus domestica and Malus domestica. V. album has been occasionally found on Pinus sylvestris and Picea abies. V. album attacks young plants with unformed bark, weakened old-growth trees with soft wood, confined to forest belts along highways, river valleys, old manor parks, and urban plantings. In parkland, V. album is found mainly on isolated trees that are well lit by the sun. The main distributor of mistletoe in the region is Bombycilla garrulus. The features of V. album dispersal in a model settlement - Dobrun village, Bryansk district, are considered, where the species has spread over the plantings of the entire village territory in 20 years. Pregenerative and young generative plants predominate in the studied population.
