In this study, naturally regenerated succesfull oriental spruce (Picea orientalis (L.) Link) and fir (Abies nordmanniana Spach. subsp. nordmanniana) mixed stand which encompass 5.8 ha area was examined. For that, seedlings in the area were studied for their relationship between growth and age. In addition, the amount of seedlings reached to area after the cuttings with large shelterwood system were determined. The age and height of fir and oriental spruce seedlings in 24 sampling areas each covering 25 square meters are measured according to square method and sampling areas systematically distributed so that samples could represent the regeneration area. Evaluating gathered data, seedlings reached to the area orderly after 1975 preperation cutting. Measurements and counts showed that orieantal spruce hold rich seeds every 4 years, however, this differentiation is not evident for fir. Evaluating height growth depending on age, correlation coefficients are found 0.9993 for oriental spruce and 0.9973 for fir, therefore the seedlings of fir and oriental spruce realized similar growth during their regeneration stage
