Abstract:	To achieve the proposed objectives researches were conducted in 16 experimental blocks where intensive treatments were applied. These experimental blocks were located in all forest formations and geographic areas where these treatments have a high percent of application. Measurements and observations concerning regeneration, particular the regeneration rate on the one hand and factors influencing regeneration such as “openings” (plots), crown density of the stand, percentage of tree volume removal etc. on the other hand were made. Quatro+ multiple regression analysis was use for statistical analysis. After determining the main factors which influencing regeneration, it was establish their optimal size and recommendations for production have been made.
Keywords:	intensive treatments, natural regeneration, openings, stand condition, crown stand density
