Restoration of tree species on fallow lands of North-West Russia

The study of the regeneration processes on the postagrogenic lands in different landscape conditions of the North-West region was carried out. The main factors for the successful regeneration of spruce and pine on postagrogenic lands are the distance to the source of seeds and the amount of deciduous tree-shrub species. The significant influence on the regeneration of tree species on the sandy postagrogenic lands has a pyrogenic effect. Depending on the landscape characteristics, the process of forming the species composition of the stand will have its own succession line of development. The growth of spruce and pine in most plots is more intensive than on the lands of the forest fund. It is necessary to regulate the regeneration processes of economically valuable species in order to involve the postagrogenic lands in economic circulation.
