An experimental stand had been established as a monoculture by planting Norway spruce on a clear-felled area in 1925. A research thinning experiment was established there in 1958. The development of control plots without anthropic interventions was studied. The spruce monoculture nearly disintegrated and the stand-forming role was taken over by species which occurred there originally as admixed ones. The stand became sparser, a spontaneous regeneration of broadleaved trees occurred. Three plots out of the 8 control ones were selected because they differed significantly in stocking and extent of natural regeneration. The undergrowth of these plots consisted of 24 woody species present in a total number of 6,000 individuals per hectare, two thirds of which were trees. Our results show that it is possible to convert a spruce monoculture to a broadleaved commercial forest using the spontaneous regeneration of trees.
