“…Research developed in the Southern Carpathians has shown that uneven-aged forests are superior to even-aged forests due to their greater continuity, stability, and protection for trees [16]. In uneven-aged forests from the Southwestern Carpathians, Ciceu et al's equations have been developed in order to predict the diameter distribution.…”

In this paper, uneven-aged stands from two important Romanian mountain areas—the Southern Carpathians and Banat Mountains—are compared with the purpose of studying the stationary conditions of uneven-aged forest stands in order to determine which management strategies are best suited to these forests and other Romanian forests with a similar structure. The study is based on silvicultural practices and natural growth conditions related to uneven-aged forest stands. The analysed surface represents 20% of Romania’s forests and includes all uneven-aged forest stands in the Southern Carpathians and half of the Romanian Western Carpathians. It has been concluded that the Southern Carpathians and Banat Mountains contain a relatively reduced percentage of uneven-aged stands compared with the total number of stands due to their composition and less favourable stationary conditions of the stands. This section highlights the novelty of the work carried out in this study on uneven-aged forest stands from two landscape reliefs in Romania.

“…Structural characteristics of old-growth forests are important starting points for defining the goals in forests that are managed on a regular basis (Vasic et al, 2018) and represent a worthy model for management and structuring of managed forests. Natural selection in primary forests may provide solutions for forest management that could lead to stands with higher stability and superior wood quality (Chivulescu et al, 2019). The significance of this research according to Bosela et al (2015) is also resembled in the fact that there is modest knowledge about competitive and facilitative interactions between trees and species in the mixed spruce-fir-beech forests.…”

Biogradska Gora National Park in Montenegro is part of the Bjelasica Mountain which belongs to the montane region of the Dinaric Alps. Biogradska Gora is one of the largest long-term preserved forests in the Southeast Europe. In this paper there were compared the main structural characteristics of the old-growth mixed forest of spruce (Picea abies L.), fir (Abies alba L.) and beech (Fagus moesiaca (Domin, Maly) Czecz.), from the preserved area of the Biogradska Gora, with similar managed forests from the same mountain. Basic insight into the structural characteristics of forests of spruce, fir and beech was obtained by analyzing tree species composition and two basic structural elements - number of trees and wood volume per unit area. The obtained data provides overview of the structural characteristics of these forests. The results revealed the production potential of the studied mixed forests. The average quantity of standing volume in old-growth forests of Biogradska Gora indicates very valuable and productive forest ecosystems. Presented data shows that forest ecosystems of spruce, fir and beech in the protected area of the National Park Biogradska Gora are characterized by structurally irregular forests with presence of old trees with relevant growing stock and optimal balance of beech and conifer species, while in managed forests on the same mountain, growing stock is very low and with structure which is far from optimal.

“…Old-growth stands have developed for a long period of time without relevant human impact. Structural characteristics of old-growth forests represent a worthy model for management and structuring of managed forests (Motta et al, 2015;Vasic et al, 2018;Chivulescu et al, 2019;Curovic et al, 2020). Mixed coniferous and deciduous forests in the area of beech, fir and spruce forests in Bosnia and Herzegovina occupy 716.200 ha.…”

The research was carried out in primeval forest stands of beech, fir and spruce (Piceo-Abieti-Fagetum illyricum) on brown dolomite soils (Janj) and dominantly shallow limestone soils (Lom). The diameter structure is typical for primeval forests with the participation of large trees in which physiological weakening is visible, especially in the Lom primeval forest. At the same time, the stands are characterized by the specifics of the transition from the terminal to the initial development phase, with a very pronounced lower floor of the stands where beech and fir dominate. Significant differences in the size of the diameter increment are characteristics for fir, which in the Lom primeval forest has a significantly higher diameter increment at the same diameters than in Janj. The current diameter increment of fir in Janj is 2.3 mm/year and in Lom 4.5 mm/year. The average current thickness growth of spruce in Janj is 0.2 mm higher on average than in Lom and amounts to 2.9 mm/year. The current thickness growth of beech in Lom is significantly higher (4.9 mm/year) than in Janj (2.3 mm/year). The average time of passage is the highest for fir in the Janj primeval forest and for the whole stand is 45 years, and the lowest for spruce in the Lom primeval forest 22 years. Beech trees in the lowest diameter classes have a significantly shorter time of passage than fir and spruce. Fir in the Janj forest has an average relative age of 85 years higher than in Lom. Spruce shows the largest difference in relative age between primeval forests in thinner diameter classes, and unlike fir, the difference in age decreases with increasing diameter.
