The development of natural succession was observed in a 70-year-old Douglas fir (Pseudotsuga menziesii Mirb. Franco) stand which had been damaged several times by stormes (1984-1986) and the late winter hurricane of 1990. The results of the survey performed in 2005 reveal that: a total of 10 different tree species comprising more than 3.000 trees per ha are present on the regeneration area; birch is the tree species which is represented by the highest number of individuals and which also includes the thickest and highest trees in the stand being followed by the tree species larch, Douglas fir and wild cherry; the quantity of more than 200 trees per ha of pre-selected future crop trees is sufficient to be able to meet in future a final future crop tree selection; the future stand is formed predominantly by the four tree species Douglas fir, birch, larch and wild cherry; releasing early and consequently birch and cherry if prerequisite for a sensitive combination between the utilization in the early stage of birches and wild cherries and the utilization in the final stage of Douglas firs and larches.
