"The experimental stand was established as a monoculture by planting Norway spruce on a clear-felled area in 1925. In 1958, research thinning experiment was established there. Con-trol plots and the study of their development without human interventions are of interest in particular. The spruce monoculture has nearly disintegrated and a stand-forming role was taken over by species which occurred there originally as admixed ones. The stand became sparser and it was associated with the spontaneous regeneration of broadleaves. Of eight control plots three were selected differing significantly in stocking and extent of natural regeneration. In the plots, the development of regeneration was studied in detail. Undergrowth was formed by 24 woody species in a total number of 6000 individuals per hectare and about two thirds of them belonged to trees. Results of the study show a possibility to convert spruce monocultures to a broadleved commercial forest using the spontaneous regeneration of trees." . .
