Аннотация: Researches of forest vegetation, forest soil, and features of the historical land use in the boreal region showed that most of the boreal forests have developed as a result of repeated forest fires and cuttings during the last millennium. These impacts simplified the structure of boreal forests and led to the wide occurrence of forests dominated by green mosses and dwarf shrubs in the ground layer of the vegetation with a relatively low species diversity and the prevalence of soil with moor and moor-moder humus horizons. At the same time forests dominated by tall herbaceous species in the ground layer and moder-mull humus in the soil have been found in fire refuges which are located in river valleys and on watersheds as well. Tall herb forests dominated by Picea spp. and Abies sibirica (in the east) have developed in areas without fire and clear-cuttings for more than 500 or 600 years, and they are the richest forest type in terms of species and structural diversity of the vegetation, in phytomass values of the ground layer, and in soil fertility. Treefalls with uprooting, pit-and-mound topography, and deadwood at different stages of decay and overgrowing are the main features of these forests. Dark coniferous forests dominated by tall herbs in the ground layer are forests at the latest successional stage that we observed in the boreal forest region of European Russia.
