The objectives of this study were to estimate the quantitative damages on regeneration, comparison of industrial and traditional skidding operations and determine how to reduce utilization damages on regeneration and selection of the best method in North of Iran. In this research, the damages to the regeneration were investigated and compared by using of industrial skidding and traditional methods in Kheirood-Kenar forest (North of Iran). Also, according to this research, rates of damage to the increment groups (cores) of seedling, juvenile and sapling was surveyed. Results from this research showed that the rates of damages were 6.48,5.34 and 9.57% in industrial skidding and 3.78,5.34 and 2.13% in traditional skidding, respectively. As perceived, the largest rates of industrial skidding were on sapling group and also rate of the damage to the whole regeneration was 6.45% in industrial skidding and 3.48% in traditional skidding. In these two states most of the damages were in the shape of destroyed and the percentages of wounded samples were the same.
