The present study was conducted in the central Rhodope mountains of north-eastern Greece. In order to analyze the Fagus sylvatica regeneration formations under open canopies, 20 plots of 2 m x 2 m were established. The plots were established, in F. sylvatica stands that were under a regeneration process using the shelterwood method, but the completion of the process has been significantly delayed. The establishment of plots was made using the simple random sampling method. In each plot, for all the F. sylvatica plants the height and diameter at the ground level (stem base) were recorded. Moreover all the F. sylvatica plants were cut and a cross section was taken from each plant, at the stem base. The number of annual growth rings (tree age) was counted in each cross section using a stereoscope. The age difference of regeneration plants inside a plot ranged from 11 to 37 years, while the height difference ranged from to 1.1 to 5.65 m. Moreover the highest mean annual height increment of all plants that were cut (and measured) was 0.31 m and the lowest was 0.035 m. The relationships of height (h) and age (t) and height and base diameter (d) of plants that were cut were found been better expressed with the equations: h= 0.105t+0.001t2 and h=0.794d-1.655/(d+1)+1.3, correspondingly. The better knowledge of growth characteristics, as well as other ecological features of F. sylvatica regeneration plants established under open canopies, will contribute to having improved silvicultural systems regarding the species as well as to more efficient silvicultural treatment of F. sylvatica regeneration formations.
