Efficiency of Thinning in Deciduous-Spruce Forest Stands in the Northern Taiga Forest Region of the European Part of the Russian Federation
Research on permanent sample plots (Arkhangelsk, Northern district forestry, Obozerskoye forestry) in birch and spruce stands with an understory layer of spruce was carried out. The sample plots were established since 1966 and differed in the intensity of thinning. The results were analyzed by corre...
