The size of each plot was 25x25m. It was established that a higher percent of dead and damaged trees of the I and II biological position was found in the unsuitable site conditions in which also appear the reduced height and diameter increments. A larger number of trees per surface unit has shown a positive effect in respect to dieback occurence. For that reason in the existing plantations a more dense canopy should be preserved and by establishing new plantations it should be necessary to apply the procedures enabling the most rapid formation of full canopy.
