Abstract:

The effects of management of even-aged beech stands on the quality of beech timber assortments by type of cut were investigated in the region of Bjelovar. The research was carried out using Croatian timber standards. Assortment tables were developed separately for thinning and intermediate felling, and separately for regeneration and final felling in accordance with the interventions of management. The average shares of assortments maintained the same ratios by quality classes regardless of the applied standards (HRN or HRN EN). The research identified the problems in production of assortments

Abstract The reclamation of landscape disturbed by mining is a topical issue in the Czech Republic and elsewhere.

Abstract:

Abstract The decline of pure spruce forests in the Beskydy Mountains in the Czech Republic and Slovakia is mainly driven by bark beetle attacks and storm events. Salvage-harvest records based on timber volume on the forest-stand level document the extent of stand failure processed by salvage logging. On the basis of these records, the stand failure proportion was expressed as the proportion of timber volume processed by salvage harvest divided by the standing timber volume over a period of 10 years (sf). Two null hypotheses to be tested are that sf is not influenced by (H1) the size of trees e

Abstract The study presented a bioeconomic modelling approach for an uneven-aged mixed forest management planning. Regression models for transition (increment), and ingrowth (regeneration) used the National Forest Inventory (NFI) of Slovakia and regional inventory data. Mortality was based on salvage logging records. Models were specific for five tree species within three forest types (FT) (oak with hornbeam and beech, beech, mixed fir-beech-spruce). Net timber prices were calculated with regard to stem quality. Tree growth depended on crown characteristics. The regression models were adjusted

Accurate information on the timber quality of hardwoods is often lacking, in particular for standing trees. In situ measurements of timber quality have the potential to improve the economic yield of a stand and may contribute to the optimal timing of a harvest and, in general, to improving forest management. Here, we used terrestrial laser scanning (TLS) to assess external timber quality metrics nondestructively. We investigated how competition intensity affected the metrics of 118 European beech (Fagus sylvatica L.) trees. We found that two newly developed TLS-based measures of external stem

The results show that these kinds of thinnings reduce volume productivity by approximately 6% compared to the maximum volume growth. The reduction in volume growth is mostly caused by the fact that the strongly released crop trees have reduced their hei

Abstract:

The efficient planning and control of timber harvesting operations is crucial to growth productivity and reducing costs, and different systems or methods are applied to obtain elevated performance. In particular, cable yarding is a highly appreciated and very efficient wood extraction method in areas that are difficult to access with ground-based extraction machines. Combined logging systems are not diffuse and not often implemented. For this reason, the use and the application of innovative methods are limited. However, some combinations have recently been observed in forest operations. This

Abstract:

Although an important part of the ecosystem, large wild herbivores (LWH), especially red deer (Cervus elaphus L.), cause significant damage to economically valuable timber in forests of Central Europe. Recent work has demonstrated that less valuable softwood broadleaved trees can act as “biological control” that helps reduce bark browsing on more valuable trees in a mixed stand. To better understand the factors that influence how much bark area and mass are removed by LWH from these broadleaved trees, we took advantage of a novel “natural” experiment that occurred after a breach in a herbivory

AbstractResearch on mixed forests has mostly focused on tree growth and productivity, or resistance and resilience in changing climate conditions, but only rarely on the effects of tree species mixing on timber quality. In particular, it is still unclear whether the numerous positive effects of mixed forests on productivity and stability come at the expense of timber quality. In this study, we used photographs of sawn boards from 90 European beech (Fagus sylvatica L.) trees of mixed and pure forest stands to analyze internal timber quality through the quality indicator knot surface that was qu

Managed forests occupy the great share of the Carpathian Ecoregion. They provide timber and other products as well as important climate- and water-regulating ecosystem services.

Therefore, there is an urgent issue of defining ecologically sound methods and volumes of forest harvesting and planting under progressing climate change. Hence, this paper describes the framework and the main methods for the study of the forest landscape prospective evolution under different scenarios aimed at the dev

The ongoing shifts in natural vegetation zones predict the expansion of European beech (Fagus sylvatica L.) into the Eastern Baltic region, suggesting it will become a potential alternative to birch (Betula pendula Roth. and Betula pubescens Ehrh.) in forest regeneration. For a successful application of alternative forest regeneration material, an evaluation of susceptibility to natural disturbances (e.g., wind) is necessary for reliable projections of timber yield in the long term.

All measured trees had already reached the age of felling. Thus, beech was over 120 years old, birch was over 70 years old, and oak was over 140 years old. On each plot, the same morphological features were measured for all trees: diameter at breast height, tree height, height of the first dead branch, height of the first live branch, and crown base.

Abstract:

As European forests face increasing threats from climate change and disturbances, diversifying tree species can be a crucial strategy to safeguard their ecological functions and climate mitigation potential. European beech is a valuable tree species with a wide distribution across Central and Western Europe. While the current natural distribution of European beech does not extend to the Baltic states, climate change models indicate a potential northward range expansion. This suggests the possibility of introducing beech to Baltic forests as a proactive measure to enhance the future resilience

Beginning around 600 AD, the predominant beech (Fagus americana) forest was partially replaced by maple (primarily Acer saccharum), oaks (Quercus spp.) and eastern white pine (P. strobus).

The use of formative pruning has been widely recommended; however, this guidance lacks a scientific basis. The experiments described here examined the effects of four levels of formative pruning on precanopy closure stands of European ash (Fraxinus excelsior L.), cherry (Prunus avium L.), European beech (Fagus sylvatica L.), and English oak (Quercus robur L.). For the faster growing ash and cherry, two prunings were applied over a 3-year period; f

In the Mediterranean area, the most common management of beech forests relies on the shelterwood system. However, more effort has been put into developing alternative silvicultural treatments to enhance the forests’ capacity to provide the higher ecosystem services. The crop-tree management system seems to perform well, particularly under the economic point of view. Moreover, it can provide higher quality timber from thinning interventions which are carried out before the end of the rotation period.
