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 to three main geobiotope (GBT) sites per FT. Forest growth was simulated with the density-dependent stand-level matrix transition model. Financial optimisation of harvest was sensitive to an interest rate. Long-time optimisation stabilised in a steady state equilibrium characterised by a stable diameter distribution. Target diameters were specific for site and tree species, and were highest for fir, a dense crown, a good stem quality, and a lower interest rate. Standing timber volume varied from 150 m 3 ha–1 (oak forests, 2% interest rate) to 400 m 3 ha –1 (beech and fir-beech-spruce forests, 0.5% interest rate). Harvested volume varied from 38 to 93 m 3 ha–1 per 10 years, stand basal area (ba) varied from 19 to 36 m 2 ha–1 depending on the site, timber price, and interest rate. The discussion pointed out that the relative low volume of the oak FT resulted from the light-demanding characteristics of oak. The mean of oak mosaic structures was lower compared to the high level of more storeys present in the single tree selection structures in beech and mixed fir-beech-spruce forests.

Abstract The purpose of the study was to determine quantitative and relative indicators that significantly affect the physical properties of gray forest soils within the park ecological trail, to show changes in the compacted soil during natural recovery. Physical properties were determined in 3-fold repetition with the help of three-dimensional cylinders, followed by the calculation of their density and porosity. Population of physiologically active roots of the upper 0.5-meter layer of gray forest soils was determined by the monolith method in 5-fold repetition. It was found out that under the influence of anthropogenic trampling, the greatest degradation changes of the studied physical indicators are manifested in the upper 10-centimeter layer of gray forest soils. An increase in the density by 32.1–38.0% and solids content of the soil by 14.1–22.8%, as well as a decrease in the volume of pores by 32.0–44.3% was recorded and mass of physiologically active roots of woody plants by 84.6–91.2%. The natural restoration of soil occurs most intensively in the upper 5-cm layer. At the same time, over a 15-year period, the following changes were observed – a decrease in density by 19.5%, the content of solid particles by 9.9%, an increase in the content of pores by 39.1% and physiologically active roots woody plants by 330.0%. Quantitative and relative indicators of their physical properties obtained for anthropogenically compacted gray forest soils explain the changes in the mass of physiologically active roots of deciduous woody plants that grow in the centers with anthropogenically compacted soils.

Abstract Norway spruce is expected to suffer from drought stress and other manifestations of climate change. This study relies on a manipulative experiment with drought-stressed and well-watered (control) seedlings, comprising five provenances of Norway spruce distributed along a steep elevational transect from 550 to 1,280 m a.s.l. within the natural range. Seedlings were subjected to measurement of physiological traits (content of phytohormones and monoterpenes, slow and fast chlorophyll a fluorescence kinetics, gas exchange, hyperspectral indices), and genotyping at 8 nuclear microsatellite loci. Comparison of the coefficient of differentiation at neutral loci ( F ST ) vs. differentiation at phenotypic traits ( P ST ) was used to identify traits underlying divergent selection. In total, 18 traits exhibited a significant P ST – FST difference. However, the consistency in differentiation patterns between drought-stressed and control plants was limited, only three traits exhibited signals of selection under both treatments. This outcome indicates that the identified differentiation patterns can only be interpreted in the context of environmental setup of the experiment, and highlights the importance of common gardens in adaptation research, as they allow both elimination of environment-induced phenotypic variation and studying genotype-by-environment interaction in physiological responses to environmental stresses.

Abstract Forestry faces the challenge of balancing the increasing demand for timber, carbon sequestration, and biodiversity protection. Biodiversity plays a crucial role in the stability and adaptability of forest ecosystems, enabling them to withstand disturbances and recover from them. Preserving biodiversity is essential for long-term survival and well-being. Enhancing biodiversity in managed forests is important because they occupy a significant area of forests in Europe. Understanding the relationships between forest production and biodiversity from various perspectives is crucial for developing effective multi-taxa management concepts. Biodiversity loss due to management practices can result in habitat destruction, fragmentation, and species displacement. Biodiversity enhances ecosystem services linked to biomass production, such as pollination, nutrient cycling, and carbon sequestration. This study reviews the relationships between biodiversity and production in Europen forests, emphasising the impacts of biodiversity on ecosystem functioning and production, as well as the effects of production indicators on biodiversity. The effects of biodiversity on productivity are often studied in the same population, most often in the tree layer. However, a lack of knowledge on how biomass production affects the diversity of other ecosystem components limits our understanding of the multifacet relationships. Forest management significantly impacts biodiversity and production, and different management systems have varying effects on forest ecosystems. Diverse ecosystems exhibit niche complementarity, resulting in increased biomass production. Sustainable practices, including land-use planning, habitat protection, agroforestry, and non-invasive species use, can mitigate the adverse effects of biomass production on biodiversity.

Abstract The carbon stock in living forest biomass was quantified based on first-cycle State Forest Inventory (SFI) measurements in permanent sample plots. The total carbon stock in above- and below-ground living biomass was assessed to be 46.9 ±0.4 × 10 9 tons C and average carbon stock at 52.1 ±0.5 t C ha–1 as of 2020. The State Forest Register (SFR), the primary source of consolidated information on Russia’s forests, estimates the forest growing stock to be 83.1 × 10 9 m 3 . The total growing stock volume in the forests, according to the SFI amounted to 113.1 × 10 9 m3. Owing to the updated and significantly higher growing stock volume, the estimate of carbon stock in living bio-mass is approximately 35% higher than previously reported. The uncertainty of the total and average carbon stocks based on SFI data was substantially lower (approximately ±1%) than that reported in previous studies (±15–30%). Methods of accounting for the carbon stock in living biomass, the results of calculations for forest lands throughout the country, units of the administrative division, and forest zoning were considered. Assessment of living biomass based on representative sampling can substantially improve the relevance and reliability of national forest reporting.
摘要采用国家森林资源调查(SFI)方法，对常住样地的森林生物量碳储量进行了定量分析。截至2020年，该地区地上、地下生物量总碳储量为46.9±0.4 × 10 9 t C，平均碳储量为52.1±0.5 t C ha-1。国家森林登记处(SFR)是俄罗斯森林综合信息的主要来源，估计森林蓄积为83.1 × 109平方米。根据SFI，森林的总蓄积量为113.1 × 109 m3。由于更新和显著增加的蓄积量，对活生物量碳储量的估计比以前报道的高约35%。基于SFI数据的总碳储量和平均碳储量的不确定性(约为±1%)明显低于以往研究报告的不确定性(±15-30%)。考虑了生物生物量碳储量的计算方法、全国林地计算结果、行政区划单位和森林区划。基于代表性抽样的活生物量评估可以大大提高国家森林报告的相关性和可靠性。

Abstract Non-native tree species – defined as those species intentionally or unintentionally introduced by humans – have long been a part of the Alpine Space, providing numerous benefits, but also posing a potential threat to native biodiversity and related ecosystem services. Compared to the urban space where non-native trees comprise most tree species, the number of non-native trees in forests and plantations is relatively low. To evaluate potential risks and benefits of non-native trees in the Alpine Space, a transnational strategy for the responsible use and management of non-native trees is needed. The goals of the strategy are to tailor management practices for a sustainable and responsible use or admixture of non-native trees, to reduce the risks connected with the invasive potential of some non-native tree species, to help forests and urban areas to adapt to climate change, and to improve coordination and cooperation regarding best practices between different regions of the Alpine Space. A proposal was developed in a four-step process including expert-based assessment, stakeholder mapping, an extensive data review, and a public consultation. For implementing the strategy fully, strong collaboration among diverse stakeholders is anticipated and robust governance and an adequate long-term and fair funding scheme is needed.

Abstract Introduced tree species have become increasingly important in the context of the ongoing climate change. This paper focuses on the dendrochronology of the most widespread introduced tree species in the British Isles – Sitka spruce (Picea sitchensis [Bong.] Carr.) – in comparable soil conditions in England, Czechia, and Slovakia. The research aims to evaluate the growth dynamics and the influence of climatic factors on this tree species while comparing it with economically main tree species in Europe – Norway spruce (Picea abies [L.] Karst.). Based on the analysis of 150 increment cores, the radial growth of Sitka spruce was on average 24.2% higher than that of Norway spruce. The highest increments in 52 to 62-year-old stands were achieved in England by both Sitka spruce (8.7 mm) and Norway spruce (7.0 mm). In terms of negative pointer years (NPYs), there was no difference in the number of years with a significantly low increment between the two species at any site. The lowest effect of climatic factors on growth was found in Czechia, while the highest was in England. Higher resistance to climate was found for Sitka compared to Norway spruce. In general, the main limiting factor for the growth was the lack of precipitation in the previous year’s vegetation season, or heavy frost in England. In Central Europe, due to low precipitation, Sitka spruce will not be a substantial introduced tree species in the future, but on suitable sites, it can achieve high production potential and play a significant role for increasing stand diversity in the face of climate change.

Abstract This paper presents non-native (NN) coniferous and deciduous tree species growth and vitality assessment on experimental research plots established in 1980, 1982 and 1985 in the Danube Lowland over an extended time period. For NN coniferous tree species, Douglas fir, grand fir and eastern white pine reached significantly higher values of diameter at breast height (dbh) and height (H) than Austrian pine. For NN deciduous tree species markedly higher values of H and dbh for black walnut compared to sweet chestnut and red oak were recorded. Damage observed in larger extent on examined NN tree species stands included illegal removal of top of stem for grand fir and presence of necrosis on trunks of sweet chestnut. Comparison of NN coniferous and deciduous tree species growth with native reference tree species showed that NN Douglas fir, grand fir, eastern white pine, red oak and black walnut were capable to achieve similar or even higher values of assessed parameters than native reference tree species. The results suggest, that cultivation of NN coniferous, including Douglas fir, eastern white pine, as well as NN deciduous tree species, including red oak and black walnut in Danube Lowland could contribute to diversification and stabilisation of wood production potential of local forest formations.

Abstract Only 1.82% of the Czech forests are covered by the introduced (exotic, non-native) tree species, they represent only a very minor part of the forest area in the Czech Republic. Despite this fact under certain circumstances and locally, they can play an important role in the forest restoration of declined forests. The main non-native tree species used in the Czech Republic are: black locust (Robinia pseudoacacia L.), Douglas-fir (Pseudotsuga menziesii [Mirbel] Franco), grand fir (Abies grandis [Douglas ex D. Don] Lindl.), black walnut (Juglans nigra L.), northern red oak (Quercus rubra L.), and blue spruce (Picea pungens Engelm.). Other tree species are cultivated on very small areas, despite their much larger potential. The aim of the presented review paper is to summarize information on the introduced tree species, available especially from national sources, and give comprehensive information concerning the potential and risk of their use in the conditions of the Czech Republic. The authors mention also other tree species eligible for silviculture under current as well as future climatic circumstances. The current area and silvicultural potential in the climate changing conditions are analysed and summarized.
捷克只有1.82%的森林被引进的(外来的，非本地的)树种所覆盖，它们只占捷克共和国森林面积的很小一部分。尽管如此，在某些情况下和当地，它们可以在森林退化的森林恢复中发挥重要作用。捷克共和国使用的主要非本地树种有:刺槐(Robinia pseudoacacia L.)、道格拉斯冷杉(Pseudotsuga menziesii [Mirbel] Franco)、冷杉(Abies grandis [Douglas ex D. Don] Lindl.)、黑核桃(Juglans nigra L.)、北红橡树(Quercus rubra L.)和蓝云杉(Picea pungens Engelm.)。其他树种的种植面积很小，尽管它们的潜力要大得多。所提交的审查文件的目的是总结关于引进树种的资料，特别是从国家来源获得的资料，并提供关于在捷克共和国条件下使用这些树种的潜力和危险的全面资料。作者还提到了在当前和未来气候条件下适合造林的其他树种。分析和总结了气候变化条件下的现有面积和造林潜力。

Abstract The impacts of climate change on forest stands are manifested in different ways and intensity. Changes in the species composition of forest stands due to the different tolerance of forest species to the effects of climate change are one of the consequences too. In this context, introduced tree species are often mentioned as a possible replacement for dying autochthonous species. Of the deciduous species, it is mainly northern red oak. The aim of this paper is to compare selected quantitative (number of trees, basal area, merchantable volume, basal area increment and volume increment) and qualitative (crop trees) characteristics in one stand of the northern red oak at the age of 54 years and in two stands of durmast oak (age 57 and 58 years) in comparable site conditions. Achieved results showed higher values in all investigated quantitative parameters in the northern red oak stand compared to durmast oak stands. The merchantable volume in the northern red oak stand was 473 m3 per hectare in the tended subplots and 742 m3 ha–1 in the control ones. On the subplots with durmast oak, it was only from 228 to 289 m3 ha–1 in the subplots with thinning and 226 to 357 m3 ha–1 in the control areas. The same results were obtained for the category of crop trees. It means 230 m3 ha–1 for the northern red oak and 28 to 121 m3 ha–1 for durmast oak. The well-known fact about the higher quantitative production of the northern red oak compared to durmast oak was confirmed.
