Abstract: 
The aim of this research was to determine the number and volume changes after the implementation of a 10 years forest management plan period and comparing of these changes with the aimed purposes. Inventories have been done systematic random sampling in 1000 m2 area plots. Diameter at breast height, control trees height and quality of first 6 m trunk length of trees with dbh more than 42.5 cm is measured and estimated. Volumes of inventoried trees were calculated based on forest management plan Taryf. To compare the mean volume and number of trees per hectare in the two inventories volume table, t test was aplicated. In order to compare trees height curves at the beginning and end of period, cloud points of control trees was drawn and then modeling with regard to it. The results showed that during the implementation, mean volume has increased 10 sylves per hectare and 47 trees has decreased in hectare, but these changes were not significant regarding to t test (d.f=32, P<0.05). After implementation, the height curve of tress and volume of trees with high degree of quality has increased. Percent volume per hectare of beech species is passed from planned mode (ideal mode) and the species hornbeam and oak nears to ideal mode. The other species have not only failed to approach the ideal goals, but also we are far from it. Reforestation rate performed is almost 50 percent of planned.
