The main objective of this study is to analyze the structural production and dynamic changes of mixed forests of fir, spruce and beech on Mt. Tara, in permanent sample plots which were exempt from the regular management over a period of more than 60 years (1955-2017). The results of the research indicate that during the analyzed period mixed forests of fir, spruce and beech have undergone a number of changes in structural and production terms. The significant presence of trees of large dimensions (volume accumulation) slowed down the developmental dynamics of these stands and made regeneration and recruitment difficult, which had a negative impact on their structural development and, in general, on the stability of these stands. The results show that selection forests are possible to achieve only with a permanent management approach and adherence to the modern principles of close-to-nature forest management. In this sense, selection cutting in the context of close-to-nature forest management is imposed as a means of accelerating the dynamics of development of these forests, repairing their structural development (by achieving and preserving their selection structure), ecological stability and functional values. On the contrary, the absence of activity and spontaneous development of these stands leads to a general devitalization and a deviation from the desired goals.
