The purpose of the experiment is to have long term measurements of growth and stand development of the two species in monoculture vs mixture. The first treatments are initiated after regeneration on sites with planted Norway spruce and naturally regenerated birch where the two species are within the same average heights. First treatment is a pre-commercial thinning aiming for stand composition in four different levels : Every block is divided in four treatments with 100 % Norway spruce (NS), 100 % Birch, mixture 33 % NS and 66 % Birch, mixture 66 % NS and 33 % birch.
