Abstract :This research was done in density stage stands of of spruce in nearly 15 hectare in Kapuköy suburb of Maçka Forest District that regenerated in different periods. 1.30 m. diameter, height, age and the longest subterminal branches of the trees in four direction were established on five trees which were most closive to the 60 points that were confirmed by systematic sampling. 1.30 m. diameter-canopy square and height-canopy square graphics were formed according to these datums. By the help of these graphics two tables were developed. One of these table was arranged according to the diameter levels with 1 cm. periods and the other was arranged according to the height levels with 0.50 m. periods. Each table shows the covered area of each tree and the numbers of the trees that must be take place in an hectare after tending, according to the diameter levels and height levels. With this research, it is suggested that in density stage spruce stands, in every 4-6 years, there must be tending cuttings in three times and the numbers of the trees that must be take place in an hectare with a decrease from thin diameter stage to thick diameter stage must be 9188 in the stands that have 1 cm breast height and 970 in the stands that have 14 cm breast height. On the other hand it is suggested that with a decrease from low heights to high heigths the number of the trees that must be take place in an hectare must be 9900 in the stands that have 1.50 m height and 1302 in the stands that have 7.50 m height.
