The effects of two silvicultural methods (shelterwood and selection methods) on quality and quantity of forest trees (along skid trails) in two beech (Fagus orientalis) stands were studied. Asalem forests in the north of Iran were selected for the research and belt transects of 10 x 100 m were used to collect the data. The plots were classified as those with low traffic, medium traffic, high traffic and control. The analysis of data showed that the degree of damage to forest stand, quality and quantity of trees on control plots was lower than along skid trails. In addition, there was a significant difference between high-quality trees in the two methods used. Furthermore, silvicultural methods showed significant differences in skewness and plummeting of low-quality trees. In general, it can be concluded that trees in selection method were in better shape than those in shelterwood method. The results suggest that the damage caused by a silvicultural method can be reduced by using better methods and pre-harvest planning.
