In the paper, the results of the complex cuttings were presented in the secondary hornbeam stands with the aim of regenerating the natural beech stands in the northern regions of Azerbaijan. For this purpose, three complex cutting procedures were carried out with a recurrence at 5 and 10 years in four sites of the secondary hornbeam stands in the northern regions. The experimental plots were characterised with: a stand density of 0.5–0.7, the age of the forest stands of 60–130 years, undergrowth of 12–25 years, a stand volume of 130–200 m3·ha–1, the beech percentage in the composition of stands of 17–28%, hornbeam 62–79% spread over the southern and northern slopes of the mountains. As a result of the complex cuttings, the share of beech trees in the composition of the parent stands increased 2.2–3.0 times. During cutting, the share of beech trees, as a part of undergrowth, increased 3.8–4.3 times. Based on the data, mathematical models were established reflecting the dynamics of the numbers of the undergrowth and the total stand volume of the forest stands depending on the participation percentage of beech trees in the parent stand.

Fagus Orientalis Lipsky

Biological invasions threaten global biodiversity and forest ecosystems; therefore, it is necessary to use appropriate strategies for combating the spread of invasive species. Natural regeneration of eastern beech (Fagus orientalis Lipsky) is considerably limited by an aggressive invasive shrub, pontic rhododendron (Rhododendron ponticum L.), in the Black Sea Region of Turkey. Therefore, the future character of the region’s forests is uncertain. The aim of this research was to evaluate the structure of beech forests with different management regimes of rhododedron and to determine the interaction among tree layer, rhododendron cover, and natural regeneration in Düzce Province using the FieldMap technology. The following variants of forests were compared: without intervention (control) and three and six years after rhododendron clearance. The results showed that tree density ranged between 175–381 trees ha−1 and stand volume between 331–589 m3 ha−1. The horizontal structure of the tree layer was mostly random, and the spatial pattern of natural regeneration was aggregated. Recruit density and height in the beech stands were significantly differentiated due to the influence of presence or absence of invasive rhododendron. Rhododendron cover ranged between 81%–97%, and woody stems amounted to 72,178–86,884 ha−1 in unmanaged forests. Canopy in the overstory did not have a significant effect on the density of regeneration and rhododendron cover. Tree layer had a significant negative influence on natural regeneration within a 4 m radius on the plots without rhododendron. However, on the plots with dense rhododendron cover, tree layer had a positive influence on regeneration within a 1.5 m radius. Natural regeneration density was significantly higher when rhododendron was cleared than the plots without intervention. On the plots without woody clearance, there was an insufficient regeneration (113–619 recruits ha−1); however, they had higher mean height compared to the sites without rhododendron. After three and six years of rhododendron clearance, the numbers of recruits in natural regeneration were 63,981 ha−1 and 105,075 ha−1, respectively. In conclusion, invasive spread of rhododendron was a limiting factor of the prosperous regeneration and tree species diversity, and manual clearance of rhododendron is recommended in managed beech forests of the study region.
