Research in derivative forests of the southern taiga on the sites of the northern forest experimental station of the Institute of forestry RAS

The directions and results of researches at the forest objects of the Institute of Forest Science RAS Northern experimental station for a 60-year period are considered. The role of various environmental factors on the development of forest phytocenoses has been determined. Peculiarities of the physicochemical properties and water regime of soils, the structure of root systems, nitrogen and carbon nutrition of phytocenosis elements in connection with forest types and cutting of stands have been revealed. As a result, a detailed characterization of the southern taiga biocenoses types was given and the soil-ecological foundations of forestry for the research region were developed. Investigations of the birch forests succession process with understorey spruce population remain relevant. This is due to insufficient knowledge of the late stages of birch forests development. The basis of forming under the canopy of birch spruce forest - the first generation or, renewed during the first 25-30 years of life of birch...
