“…Cutting practices have a considerable effect on the stand structure, but changes in the horizontal distribution are quite slow. More notable changes might be found in the vertical structure with the intensive natural regeneration (Vacek et al 2018).…”

The right timing for replacing mature and over-mature forest stands with a young generation of trees is evident as it ensures continuity in forest management. The study aimed to assess the efficiency of cutting practices in mature stands of Tilia cordata Mill. Mono-dominant and poly-dominant, even- and different-aged linden tree forests in the southern Urals were studied. The study found that in the first years following the small scale forest cutting practices (the Murakhtanov method), retention trees of Tilia cordata Mill. showed longer crowns (by 0.3 ± 0.01 m) and higher crown diameter indices (by 0.11 ± 0.04 m). A single selection showed that nectar secretion potential was 2.1 ± 0.06 mg/flower in the first assessment year, the index was 1.8 ± 0.03 mg/flower in the control forest area where no trees were cut. In the third assessment year, nectar secretion potential rose to 4.1 ± 0.04 mg/flower, while the index fell to 2.0 ± 0.01 mg/flower in the control forest area. The comparative analysis of the shoot growth capacity in stools of different diameters showed that shoots regrew from 82% of stumps. Shoots did not regrow from stumps affected by rot, those ones destroyed in the cutting process, and also from stumps of 59 – 62 cm in diameter.

“…In Europe, attention has recently been paid to mixed oak and beech stands as important timber production species (del Río et al 2014;Vacek et al 2018Vacek et al , 2019a. In oak-hornbeam stands, the number of trees ranging between 1 268 and 1 512 individuals per ha in 1998 indicates very variable medium-aged stands and a significant influence of the original way of pasture management.…”

“…Slightly different results were given by Rozas (2003), who presented a clustered structure for old-growth beech-oak lowland stands, mainly due to gaps in the canopy that arise after the death of dominant trees. Vacek et al (2018) also presented relatively heterogeneous results for oak stands, where the high forest showed predominantly random distribution while the low forest was characteristically clustered. In spruce and herb-rich beech stands, spatial distribution of trees was random with tendency to regular https://doi.org/10.17221/96/2020-JFS distribution.…”

The paper presents the results of a study on the impact of forest stand structure and development in 1998 to 2018 on the occurrence of dog’s tooth violets (Erythronium dens-canis L.) in the Medník National Nature Monument, Czech Republic. The research was carried out in mixed European hornbeam and sessile oak stands, herb-rich European beech stands and the Sázava-river Norway spruce ecotype stands. The site and stand characteristics of the following three forest stand types were compared: 1) oak-hornbeam forests, 2) herb-rich beech forests and 3) secondary spruce forests. The results showed that the ratio of sterile and fertile plants was 2.9 to 1. The occurrence of E. dens-canis was higher in older stands with differentiated structure. On the contrary, stands characterized by a higher number of trees and basal area negatively affected the population size of E. dens‑canis. Significantly, the density of E. dens-canis decreased with increasing stand density index (SDI) and increased with increasing diameter differentiation index in relation to tree neighbours (TMd). During the period of 20 years, the E. dens-canis population increased by 40.4% on permanent research plots, while the highest changes were observed on spruce plots (+92.1%) and the lowest increase was in oak-hornbeam forests (+18.0%). The highest numbers of E. dens-canis plants were found in herb-rich beech forests (1 774 plants·ha–1), lower numbers occurred in oak-hornbeam forests (784 plants·ha–1) and minimal in secondary spruce forests (51 plants·ha–1).

“…Conditions of habitat, species composition, age, density of stand, configuration of stand, economic activity in forest, environmental drivers, natural catastrophes, in particular fires, hurricanes, are the factors influencing diameter distribution in forest stand. Diameter distribution changes over time (Vacek et al 2018).…”

Natural-production conditions determine operational efficiency of logging machines. This influence needs to be taken into account at different levels of forest management. It is necessary to allocate areas with similar natural-production conditions for effective forest management. It allows simplifying the decision making process for selecting logging technology and machines. The purpose of this study was to establish areas with similar natural and production conditions in the European North of Russia (ENR). In addition, for small enterprises, we recommend logging technologies and logging machines that can be used in established areas. We determined the indicators of the natural-production conditions of ENR regions and compared them. Cluster analysis was used to compare the indicators. We found that ENR can be divided into three main zones A, B, C and two subzones B1 and B2 with similar natural-production conditions. In the zones A, B and the subzones B1 and B2, small logging enterprises should use a harvester and a forwarder. In the zone C, the enterprises can use a logging system including a harvester and a forwarder or a logging system including a feller buncher, a skidder and a processor. The logging system should be based on the light class of logging machines for the zone A, the medium class or the heavy class for the zones B, C and the subzones B1, B2, the heavy class of machines for the zone C.
