This review uses a case study based on an executed afforestation project to comprehensively describe the administrative procedure regarding afforestation of agricultural land in the Czech Republic, Central Europe. We consider the official proceedings for obtaining a permit to land-use change (i.e. changing the nature of land use and the mode of land use in the real estate cadastre) as a very complex and protracted procedure, which can substantially reduce the motivation of people to establish new forests. Therefore, we propose a simplification of the administration process of land-use change. The main idea is to make the procedure as simple as possible in those areas where afforestation is desirable, especially from the environmental point of view. It assumes the possibility of quick, precise and, if possible, automatic distinction whether the afforestation is suitable or not. The situation in the Czech Republic is compared with the surrounding Central-European countries: Poland and Slovakia. In these countries, the official procedure connected with afforestation seems to be rather less complicated.

In recent decades, the interest in searching for procedures and strategies to make energetic and economic use of residues from different industries has been an important part of the political agenda. There are several methods to determine the volume of residues from the forestry industry, but they are too time-consuming to apply. The objective of the present study was to establish a simpler and more efficient method to quantify the volume of residues from the forest industry. Ten controlled piles were made with residues from a private sawmill in the city of Durango, Mexico. To calculate the volume, two manual methods and one automatic method were used to calculate the stacking coefficient of the piles, while the water immersion method was used to calculate the real volume. A completely random experimental design was used for the analysis, where an analysis of variance and mean comparisons were performed at a significance level of P ≤ 0.05. The results of the study show that the threshold segmentation method is faster, more practical and efficient than the other methods used. The estimation of the volume of these residues will contribute to generating sustainable alternatives for the development and use of forest industry resources.

A lack or, conversely, an excess of water during the first growing seasons can bring about a slowdown in the growth of plants, their stagnation or even death. The necessary amount of water is not known for most hybrids of Paulownia. Therefore, one species and four hybrids were subjected to three regimes of watering to find out their impacts on plant height, radial growth, the amount of leaf biomass and leaf area. We planted 30 plants of each species/hybrid into plant pots under a shelter. At the end of the growing season, we measured the above-mentioned parameters. Our results showed that: (i) generally, a mean precipitation of 50 mm per month in the growing season ('per month') seems to be insufficient for optimal growth of Paulownia plants in the first years after planting; (ii) each species/hybrid reacts differently to the amount of water – P. Shan Tong grows better with 100 mm per month, P. tomentosa with 150 mm (and more) per month and the growth parameters of the others did not change (and remained low) with different amounts of water (P. Hybrid 9502, P. Bellissia^® and P. Clon in vitro 112^®).

The sustainable management of European forest ecosystems necessitates innovative mechanisation solutions to address operational challenges in hilly, mountainous, and ecologically sensitive terrains. Hybrid-drive unmanned vehicles (HDUVs) present a transformative potential by integrating fuel-electric powertrains with autonomous navigation systems, enabling energy-efficient operations with minimal environmental impact. This review synthesises and critically analyses advancements in three critical domains: (i) dynamic modelling and chassis design for enhanced terrain adaptability, (ii) hybrid powertrain optimisation for reduced emissions and extended operational range, and (iii) the integration of unmanned systems for precision forestry tasks. By examining multi-body dynamics, power management strategies, and AI-driven navigation algorithms, we elucidate the role of HDUVs in improving operational efficiency while mitigating soil disturbance and carbon footprint. The review identifies prevailing research gaps and suggests that future work should prioritise the development of standardised testing protocols and foster cross-disciplinary collaboration to align HDUV development with EU biodiversity and climate objectives.

Coppice is the oldest form of systematic and sustainable use of forests, and is currently applied on about 29 million ha (about 14% of total forest land area) in Europe. It had its maximum spread in the 16^th century, when an estimated 36% of all forested land in Europe was managed for coppice. Coppice forests were the most important source of fuelwood until the mid-19^th century, when firewood and charcoal were substituted by alternative fuels, and the demand for construction wood increased. Consequently, coppices (both low and coppice-with-standards) started to be converted to high forests, and the process was driven by national policies and/or subsidies, which is still the situation in some European countries. During the 20^th century, coppicing was abandoned in many places across Europe due to the abandonment of the countryside and population migration into cities, as well as changes in socio-economic conditions, technical advances and political restrictions. However, coppicing is still important in many European countries as the main source of firewood for the rural population, who has limited access to other sources of energy. In this context, this paper presents the most important characteristics of this complex abandonment/management/conversion picture, emphasising the pros and cons for the future of coppices across Europe.

In recent years, hyperspectral imaging has been widely adopted in agriculture and plant phenotyping, while its application in forestry has been increasing. From that point onward, hyperspectral imaging has become a valuable tool for plant phenotyping, enabling the assessment of a broad range of plant traits. Given that seedlings of forest trees are one of the most widely used types of forest planting stock, advancements in hyperspectral technology have created new possibilities for improving seedling quality assessment. High-quality forest seedlings are important for the successful establishment of forest stands, especially after outplanting within restoration initiatives. Even though hyperspectral imaging brings numerous advantages, continued technological improvements are necessary to address its several limitations and challenges. Despite its widespread use in agricultural phenotyping, applications in forest nursery production remain limited. Therefore, this review focuses on research involving hyperspectral imaging in forest seedling production and its potential for assessing seedling quality parameters.

Uneven-aged forest management and Continuous Cover Forestry (CCF) are increasingly discussed as adaptive silvicultural approaches capable of improving forest resilience under climate change, increasing disturbance frequency, and growing uncertainty in forest ecosystems. However, the conversion of structurally homogeneous stands into uneven-aged structures represents a complex optimisation problem involving economic performance, structural stability, regeneration continuity, and long-term sustainability. This study presents a multi-period optimisation framework based on size-class dynamics, transition matrices, and Liocourt-based structural regulation. The model is formulated as a quadratic optimisation problem that maximises net present value while simultaneously minimising deviations from a target uneven-aged diameter distribution. A hypothetical case study was developed to analyse the conversion of structurally homogeneous stands toward uneven-aged structures regulated by Liocourt distributions. The optimisation experiments included extensive sensitivity analyses involving combinations of q-ratio, target basal area, recruitment intensity, growth dynamics, and mortality parameters. Results demonstrate that recruitment and lower diameter class dynamics represent the dominant drivers of successful structural conversion, while harvesting alone cannot compensate for insufficient regeneration inflow. The analysis further confirms that Liocourt distributions should not be interpreted as universal biological equilibria but rather as regulatory and optimisation targets dependent on ecological, silvicultural, and economic conditions.

Adequate assessment of ecosystem services is important for the development of policies and management plans related to forestry activities and the environment. Carefully identified ecosystem values can determine which options policy makers should prioritize to provide the greatest benefit. There are numerous methods used by researchers to evaluate ecosystem services. The most widely applied methods are monetary valuation methods, they are often deemed to be the most pragmatic language when it comes to communication with political and business institutions. The main goal of this review is to analyse available literature using the methodology particular to the scoping review approach in order to identify and describe valuation methods that can be applied for monetary assessment of ecosystem services. As a result of the scoping review, over 20 monetary valuation techniques (including several less common methods such as willingness to sell and Delphi method) were derived from 16 literature sources. In the process of compiling the range of different methods, a few flaws and gaps in the communication of methods were observed such as lack of consistency in the names of different methods and mixing up concepts. In addition, a few areas for future research are suggested.

Forest cover plays an important role in terms of biodiversity and the environment. The Beni Salah national forest in its part which is located in the Guelma province in the extreme northeast of Algeria is an illustrative example where forest fires represent the chronic phenomenon which weighs heavily on this forest. The present study comes after a forest fire that occurred in 2021, when 3 000 ha of this forest were ravaged by forest fires according to the conservation of forests of Guelma. The main objective of this research is to map the severity of burns and estimate the severely burned area using Sentinel-2 satellite images based on remote sensing indices such as Normalized Difference Vegetation Index (NDVI), Differenced Normalized Difference Vegetation Index (dNDVI), Normalized Burn Ratio (NBR), Differenced Normalized Burn Ratio (dNBR), Green Normalized Difference Vegetation Index (GNDVI), Differenced Green Normalized Difference Vegetation Index (dGNDVI), Burn Area Index (BAI) and Relativized Burn Ratio (RBR). The result obtained revealed that 28.23% of the study area represents a seriously burned area. The established burn severity map is a real decision-making tool, but it still has certain limitations.

This paper deals with the verification of models for the calculation of the contact area with the soil using data measured during the testing of a tractor-and-trailer unit. The main emphasis was put on the method of calculating the contact area by means of a super ellipse. The comparison included calculation models with the input parameters of contact length and contact width of the tyre. These parameters were compared with values measured in the field where the main variables were tyre dimensions, inflation pressure and load. Results of comparisons show that the method of calculating the contact area using a super ellipse exhibited the best match with the measured values of all compared calculation models (81% in super ellipse with measured half-axes and 75% in super ellipse with calculated half-axes). As to trailer tyres, the match of measured values and those calculated using a super ellipse was even 95%. In the second step, also some empirical models for calculating the contact area were compared with the measured data, not entered by contact length and contact width as variables. Some of these models show a very good match with the measured data, which can be compared, or it is even higher than the calculation by means of a super ellipse. With the specified tyre deformation, however, we consider the model of calculation using a super ellipse as more appropriate for determining the size of contact area as it focuses on the geometry of tyre contact with the ground.

This study aimed to evaluate ozone (O₃) phytotoxic potential using AOT40F (accumulated O₃ concentration over a threshold of 40 ppb for forest protection), document visible foliar O₃ injury across eight forest monitoring plots, analyse MDA (malondialdehyde) content in leaves and needles, and assess the relationship between visible injury and plot conditions. Initial findings are based on data from the 2021 and 2022 vegetation seasons. AOT40F values exceeded the critical level of 5 ppm·h^–1 at all plots, with higher values in 2022. The correlation between AOT40F and visible injury was inconsistent; in 2021, minimal visible O₃ injuries were observed, while these were more frequent in 2022, notably on Fagus sylvatica leaves. The altitude effect on O₃ concentration indicates greater vegetation damage at higher altitudes. In contrast, the AOT40F-altitude relation was not significant. The 2021 vegetation season was characterised by lower temperatures and higher relative air humidity and soil moisture in comparison to 2022. Stomatal conductance conditions were similar in both years, except for lower soil moisture in 2022. Soil moisture, air humidity, and temperature together accounted for about 50% of the variance in visible injury in 2022. The findings suggest that the AOT40F capability for predicting damage to vegetation is limited and highlight the importance of future research focusing on stomatal O₃ flux-based approaches.

A root detector is a non-destructive technology developed to indicate the radial distribution of tree roots, which are not often visible on the surface. This study aims to assess the accuracy of the root detector in estimating the radial distribution of both exposed and buried tree roots. Six Agathis loranthifolia Salisb. trees were selected, three with exposed roots and three with buried roots. The Fakopp® root detector, an acoustic-based tool, was used in this study. Root estimation was based on a combination of threshold values (> 400 m·s^–1), average values, and the peak of the sound wave velocity. Soil excavation was manually conducted at a depth of 30 cm within a 100 cm radius of the tree trunk. The results showed that under similar soil conditions, the root detector achieved an accuracy of over 80% in detecting the actual radial root distribution, as validated by the excavation method. Root diameter exhibited the strongest correlation with sound velocity in detecting lateral roots. However, root depth and inclination angle contributed to detection inaccuracies in estimating the radial distribution of lateral roots.

This paper analyses the accounting and tax treatment of forests as biological assets in the Czech Republic under Act No. 563/1991 Coll., on Accounting, and its implementing regulations. It compares national approaches with the International Financial Reporting Standards (IFRS), focusing on the International Accounting Standard IAS 41 – Agriculture. A comparative-analytical method was used to identify key differences in classification, valuation, and reporting practices. Czech legislation values forests at historical cost and classifies them as non-depreciable land, whereas IFRS requires fair value measurement, capturing biological transformation and the economic potential of forest ecosystems. The findings show that while the Czech framework ensures legal clarity and tax alignment, it lacks integration with environmental accounting frameworks such as the United Nations System of Integrated Environmental Economic Accounts (SEEA) and does not reflect ecosystem services or ESG (environmental, social, governance) reporting needs. In contrast, IFRS provides a dynamic representation of forest assets, supporting transparency and comparability in international contexts. The study contributes to the ongoing harmonisation debate by offering recommendations to improve the alignment of Czech accounting with international standards, thus supporting sustainable forest management and enhancing investment credibility. Its originality lies in combining legislative analysis with international practice review, highlighting the gap between ecological value and financial reporting in forestry.

This article presents a doctrinal legal analysis of judicial practice concerning criminal tax offences in the Czech timber trade, with a primary focus on VAT fraud. Court decisions were examined thematically to identify key categories of fraud schemes, recurring evidentiary challenges, and patterns of judicial reasoning. Administrative and regulatory frameworks, such as the EU Timber Regulation (EUTR), have played only a marginal role in Czech judicial practice, with a single decision explicitly referring to the EUTR. The findings highlight how courts rely on indicators such as fictitious supply chains, economically irrational transactions, and incomplete documentation to establish fraudulent intent. The study contributes to a better understanding of judicial reasoning in tax fraud cases and offers evidence-based recommendations for strengthening enforcement practice. The article focuses on Criminal Tax Law, i.e. examples of tax fraud in the timber trade that were not dealt with by the tax authorities as administrative offences but were assessed as criminal tax offences falling within the jurisdiction of criminal courts. Criminal Tax Law is a subfield of Czech Tax Law dealing with criminal activity in the area of tax and fee administration. (Lichnovský et al. 2020). The article contains all court decisions in the field of Criminal Tax Law dealing with the issue of timber trade. The article deals only with the criminal law aspects of tax law. No other court decisions were found in the Automated Legal Information System (ASPI). The ASPI legal information system contains only one court decision relating to the EUTR Regulation, which is cited below. Criminal cases in the field of forestry and timber industry constitute only a small part of the entire criminal tax law. In terms of the method of committing the criminal activity (issuing fictitious invoices, fictitious deliveries of goods), these are common frauds common to all economic activities.

Disturbance regimes in Central European mountain forests are changing under the ongoing climate change, raising questions about how protected areas should respond to increasingly frequent windthrow and bark beetle outbreaks. In Tatra National Park, a major windstorm in 2004 triggered a landscape-scale bark beetle eruption that challenged long-standing expectations that non-intervention alone could safeguard forest ecosystems. Using the Socio-Ecological Systems framework, we combined long-term field observations with archival sources and stakeholder interviews to examine how ecological dynamics, governance structures, and actor perspectives interacted during and after the outbreak. We show that warming, abundant post-storm breeding substrate, and legacy Norwegian spruce (Picea abies) monocultures reduced forest resilience and enabled successive beetle waves. Governance fragmentation led to delayed decision-making, allowing large volumes of wind-felled timber to remain untreated and facilitating its spread into high-naturalness stands. In contrast, evidence from other European countries suggests that timely, spatially focused measures can reduce outbreak duration without compromising conservation values. Our results indicate that in disturbance-prone, spruce-dominated forest systems experiencing climate change, a combination of strict protection in core areas and timely, selective measures in adjacent zones is more likely to maintain resilience and support conservation outcomes than strictly passive or fully interventionist approaches.

Forest ecosystems provide multiple ecosystem services (ES), including timber production, carbon sequestration, biodiversity conservation, soil protection, and cultural functions. Integrating these often conflicting objectives into forest management planning represents a complex multi-criteria decision-making (MCDA) problem. This study proposes a practical MCDA framework for evaluating selected ecosystem services within the Czech forest management planning system (LHP/LHO). The framework integrates forest growth simulation, ecosystem service indicators, GIS data, and MCDA methods. Five indicators were evaluated: wood production, carbon stock, erosion risk, biodiversity, and cultural ecosystem value. Criteria weights were derived using the analytical hierarchy process (AHP), while management scenarios were ranked using TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) and PROMETHEE methods. A pilot simulation over a 100-year horizon compared four forest management scenarios: clear-cutting, shelterwood, selective, and non-intervention management. Selective management achieved the highest multifunctional sustainability [composite sustainability index (CSI) = 0.855], combining relatively high production with strong ecological and cultural performance. Clear-cutting management maximised short-term production but showed higher erosion risk and lower biodiversity. The study demonstrates the potential of MCDA to support transparent multifunctional forest management under Central European conditions.

The study aims to identify the difference between the current and future strategic management of forest ecosystem services (FES) portfolios in public enterprises of Slovakia. The case studies focus on forest enterprises in Košice, Banská Štiavnica, Kremnica, and Bratislava, representing the best practice examples of providing cultural services in the country. A marketing decision-making model, Boston Consulting Group (BCG) matrix, was used to analyse each company's current FES portfolio. Content analysis assessed the data collected from interviews with managers of the public forest enterprises. Duncker's forest management approaches classification was applied to evaluate the future strategic management of the FES portfolio, and a horizon of 10 years was set. According to the results, the urban forest enterprise in Bratislava is an example of receiving a subsidy from the capital for building and reconstructing recreational facilities. Therefore, this FES portfolio is and will be the most balanced. The portfolio of the forest enterprises in Košice, Kremnica, and Banská Štiavnica will remain unchanged for the next decade, and they plan to use a combination management approach that caters to economic, ecological, and social needs and objectives. Urban forests in Bratislava will focus even more on close-to-nature forestry.

Results obtained from the research study focused on the functional parameters of five saw chains tested on a test bench equipped with an electrically driven chain saw brought a number of findings. One of the most important of them is the significant difference between the cutting rates of round and square chains. The cutting rate of square chains R = 27.9 cm²·s^–1 is about 12% higher than the cutting rate of round chains. The influence of the chain construction on the chain cutting rate was conclusively demonstrated – the cutting rate of chains with a square profile is higher than the cutting rate of round-profile chains. It was further found out that although the specific energy E_m = 77.8 Ws·cm^–2 is by ca. 7% lower in the square chain than in the round chain, Student's t-test did not reveal any statistically significant difference in the data on the specific energy consumption of round and square chains, i.e. the influence of the chain design on the specific energy consumption of the chain at cutting was not clearly demonstrated. Other findings, for example, showed that working with a loose saw chain on the guide bar impairs parameters of the chain operation or that energy demands of cutting with the saw chain are directly proportional to wood density (hardness) and increase with the decreasing wood moisture. Yet another finding was learning the energy flow structure, which indicated that 46% of total power input is consumed by the electric motor alone for its operation while only about 7% goes for driving the chain movement along the bar (without cutting) and power input required for cutting is approximately 46%.

This study investigates differences in carbon storage between managed and unmanaged forests in the growth conditions of Central Europe. Norway spruce (Picea abies), European beech (Fagus sylvatica) and pedunculate oak (Quercus robur) dominated forest types were considered, as these are the most common forest species in the Czech Republic. Scots pine (Pinus sylvestris), as the second most common species, was excluded due to lacking relevant reference data on unmanaged forests. Managed and unmanaged variants of each forest type were assessed in terms of carbon sequestered in biomass, dead wood and harvested wood products (in the managed variant). Harvested wood products yielded during two rotation periods were considered, including their substitution effect as well as respiratory losses, to fully assess their contribution to carbon balance. Average carbon storage in the above-ground biomass and deadwood was lower in the managed forest compared to the unmanaged forest in comparable growth conditions. However, this difference is in our model examples compensated by carbon stored in the harvested wood products including their substitution effect in the managed forests of Norway spruce and pedunculate oak. Contrarily, managed European beech forests showed, in our case, slightly lower carbon storage compared to the unmanaged alternative. The estimates for all species are considered to be rather conservative due to the assumed factors affecting the results. Due to generally limited comparative data on unmanaged forests in the region, the results should be interpreted with caution.

An unprecedented bark beetle outbreak has led to a significant decline in forest cover in Central Europe in the last 10 years, affecting an area estimated at more than 200 000 ha in the Czech Republic. Among the many ecological threats associated with extensive clearings, the potential alteration of hydrological processes is one of the most important. Therefore, after 2022, the precipitation–runoff balance in three catchments in the Jeseníky Mts. area was studied. This study focuses on the rainfall variability within the area, which was measured using 24 rain gauges deployed to cover different altitudes as well as the geographical exposures of the mountain catchments. Precipitation data was evaluated based on seven-day totals within the frost-free period. There was a significant increase in precipitation with altitude (12% increase for every 100 m a.s.l.) but only in less than half (48.7%) of the evaluated periods. No significant trend was demonstrated in the remaining periods, and a negative trend in precipitation with altitude was identified in 8.9% of cases. Additionally, the role of exposure was insignificant, although a tendency towards slightly lower precipitation was found for the eastern exposure at altitudes up to 1 000 m a.s.l., which may be related to the prevailing wind direction. We concluded that even a relatively dense monitoring network is not necessarily sufficient to provide accurate precipitation data in forested catchments, especially in mountain areas. Under such conditions, the use of complex models that also use radar data is recommended.

The increasing global demand for energy and the negative environmental impacts of fossil fuel exploitation have driven interest in sustainable energy solutions, such as wood. The Russian Federation, as one of the world's largest pellet producers, has an opportunity to utilise pellets domestically. This study addresses the lack of publicly available life cycle assessment (LCA) studies on pellet production and utilisation in Russia, specifically examining the environmental impact of residential heat production from locally produced wood pellets. Utilising primary data from the Northwest region, the study follows ISO 14040 and 14044 standards and employs the ReCiPe 2016 (H) Midpoint v. 1.1 method to assess environmental impacts. The results indicate that the production of pellets is the dominant contributor to the global warming impact category, marine eutrophication, and fossil resource scarcity, while transportation has the least impact across all categories. Sensitivity analyses confirm the robustness of these findings, revealing that using natural gas for pellet drying increases emissions for global warming and fossil resource scarcity, and increasing transportation distance significantly raises emissions across all categories. The findings provide valuable insights for policymakers and stakeholders aiming to enhance the sustainability of similar bioenergy systems.

Understanding society's demand for forest ecosystem services (FES) is crucial for effective forest management and the development of supportive instruments, such as payments for ecosystem services (PES). This study surveyed visitors at 'Forestry Days 2024' in Slovakia through face-to-face questionnaires, capturing their views on FES and necessary management changes. Results show that regulating services and biodiversity are prioritised over cultural and provisioning FES. Respondents indicated a clear need for changes in forest management to reflect their FES preferences. Notably, perceptions of specific FES varied by gender, age, forestry background, and forest ownership but not by residence type. Public PES were considered the most acceptable policy for enhancing FES management, providing valuable insight for aligning public preferences with sustainable practices in Slovakia.

Dragon trees, arborescent members of the genus Dracaena (Asparagaceae), provide a wide range of ecosystem services and have been ethnobotanically important plants since ancient times. Currently, their relictual distribution is fragmented, populations are isolated and often under threat. We provide a brief overview of scientific studies and the state of knowledge on dragon trees published since 2020, when the last review was published. More than 120 papers dealing with dragon trees have appeared, indicating a significant interest in their research, cultural uses and conservation. The most intensively investigated species are Dracaena cochinchinensis, D. cinnabari, D. draco and D. cambodiana. Almost half of the papers deal with the chemical composition of resin and its bioactivity, in addition to studies on ecology, conservation and genetics. Only a few studies are devoted to taxonomy and ethnobotany.

The aim of the study was to find out whether and how the forest soil compaction resulting from the traffic of forest logging machines results in the increased soil air concentration of CO₂, occurring over a longer period of time and in different seasons of the year. Changes in the soil air CO₂ concentrations were monitored in two periods: in winter (cold period) and in summer (warm period). CO₂ concentrations were measured in compacted and non-compacted soil using a certified measurement. In addition to the soil concentration of CO₂, air temperature, soil temperature and soil moisture content were measured. The research was conducted in the Czech Republic. The obtained data was subjected to statistical analyses (Student's t-test; correlation analysis). The results of the study confirm the long-term influence of soil compaction by the traffic of forest machinery on the CO₂ concentration in soil in both seasons (cold and warm). The concentration of CO₂ in the air of compacted soil was always significantly higher in both periods than the CO₂ concentration in the air of non-compacted soil (control). Thus, the negative influence of soil compaction was clearly demonstrated as a result of a single pass of forestry machines over the soil surface.

The forest certification is a voluntary programme to ensure that the timber harvested from forests is processed in a sustainable manner by following specific standards. The Programme for the Endorsement of Forest Certification (PEFC) was introduced in 1999 using the bottom-up approach, and it gives flexibility for a country to set up their own PEFC standard based on current practices in sustainable forest management (SFM), regulation, and governance. This practice has led to the development of various PEFC standards for each country; thus, the impact of PEFC certification differs from country to country. In accordance with that, this study aimed to evaluate the PEFC standard application in developed and developing countries, namely in Sweden and Malaysia. The study also analysed the impact of forest certification on governance and economic aspects within Asia Pacific and Europe. The outcome of this study indicates that the PEFC standards developed by these countries showed similarities; for example, both countries are focusing on social and environmental requirements. Meanwhile, the differences were shown in the criteria, terms used, and the focus area. The impact analysis exhibited that countries are facing similar issues, especially market access and premium prices. This study revealed that each country develops different standards based on current practices, forest diversification, and regulations.

The forest dynamics of the Ore Mountains (Krušné hory), Czech Republic, reveal a historical decline of natural mixed forests, especially those dominated by the Hercynian mixture and European beech (Fagus sylvatica L.), due to the expansion of metallurgy and glassmaking in the 15^th century. This led to large-scale reforestation with Norway spruce [Picea abies (L.) Karst.], resulting in single-layered monocultures. Although these monocultures provided valuable timber, they proved highly susceptible to both biotic and abiotic stressors. Throughout the 20^th century, the stability of these forests further deteriorated due to air pollution (notably SO₂ emissions), the unsuitable selection of substitute species, and the proliferation of pathogens. The cumulative impact of these disturbances caused soil acidification, degradation, and weed encroachment, severely limiting the regenerative capacity of forest ecosystems in this region. This article presents model examples of species composition shifts, spatial structure changes, and evolving management practices in the Ore Mountains. It discusses strategies for establishing diverse and resilient stands that align with long-term forest planning goals. These approaches aim to maintain both productive and ecological functions of forests under changing environmental conditions while minimising restoration costs. Importantly, forest management and conversion strategies must also account for economic optimisation, ensuring that ecological goals are met in a financially viable manner. The strategies and case studies presented here offer promising, albeit preliminary, directions for future forest management. Their broader application will require further refinement and long-term experimental validation to ensure sustainability in both ecological and economic terms.

Forest bathing is gaining attention for its health and well-being benefits, leading to growing interest among academics, policymakers, and practitioners. While most studies have focused on its physiological and psychological effects, less is known about how different stakeholders perceive the characteristics that make forest bathing effective and meaningful. This study explored expert and non-expert perspectives on forest bathing in Italy through the Q-methodology, aiming to identify shared and divergent views on key aspects such as site features, accessibility, and perceived benefits. The results highlighted four distinct viewpoints: a scientific-health-oriented perspective emphasising medical efficacy (mainly experts); a preference for more naturalness and ecological integrity (mainly non-experts); a possible socio-economic opportunity (mainly non-experts); and a preference for a more managed forest environment with supporting structures (mainly experts). Despite differences, consensus emerged on several points, including the cultural and physical relevance of forest bathing and the importance of inclusive accessibility while preserving low-impact environments. The findings highlighted the potential of Q-methodology to capture the plurality of stakeholder voices, offering a basis for more inclusive planning and policy development in the context of nature-based well-being initiatives.

Soil nitrogen (N) cycling plays a pivotal role in forest ecosystem productivity and nutrient regulation. This review synthesises recent advances in understanding how forest management practices influence soil nitrogen cycling and highlights future research priorities for elucidating underlying mechanisms and optimising forest ecosystem functioning (Figure 1). Management interventions such as thinning, species composition adjustment, and understory vegetation control have been shown to affect N inputs and transformation pathways by modifying litter quality, microbial community structure, and N-cycling enzyme activities. However, current findings remain inconsistent, and mechanistic insights are still limited. Future research should focus on disentangling the multi-scale, multifactorial interactions through which forest management regulates soil N cycling. Integrative approaches that link molecular biology with ecosystem-level processes are needed to clarify the interplay among microbial dynamics, enzyme activity, root exudates, and soil physicochemical properties across spatial and temporal scales. In addition, research should explore how forest management affects community structure, litter inputs, soil aggregation, and subsurface biochemical processes to reveal the synergistic regulation of nitrogen cycling by biological, physical, and chemical drivers. Establishing long-term monitoring networks across a range of forest types and climatic regimes, combined with tools such as metagenomics, high-throughput sequencing, and stable isotope tracing, will enable the precise characterisation of key nitrogen-cycling genes and fluxes. In the context of global environmental change, it is also crucial to assess how forest management modulates the coupling of nitrogen, carbon, and water cycles and the resultant ecological feedbacks.

The large number of charcoal kiln sites (CHKS) preserved as cultural heritage monuments demonstrates how extensive forest management for charcoal production has influenced the present forest dynamics and contributed to industrial expansion. Therefore, it is necessary not only to have a reliable methodology for detecting and documenting individual kiln sites for management and protection purposes but also to present the results in a meaningful way to the public. The aim is to optimise the data processing workflow from airborne laser scanning (ALS) point cloud to printable model (from LAS format to STL), determine the influence of vegetation cover at the time of data collection on the quality of the resulting model, verify the quality of printed models using photogrammetry, and finally, produce printed models of CHKS as cultural heritage objects in a form that can be effectively presented to the public. After comparison of different ground filtering methods, we conclude that the most accurate method for creating a precise ground representation for our area of interest was the Cloth Simulation Filtering (CSF) algorithm. From the filtered point cloud, a high-resolution raster surface was generated, which served as the basis for CHKS detection. Using our proposed methodology – combining the topographic position index (TPI) with a 0–5% slope threshold – we achieved a significant improvement in detection performance compared to using a zero-slope threshold alone, with the F1 score increasing from 0.667 to 1.000. Subsequently, the most representative kiln site was selected, which was then processed and optimised using various software tools, resulting in an exchangeable STL file suitable for dissemination and 3D printing. The accuracy of the printable model was then evaluated. We conclude that point cloud from the winter flight campaign achieved higher accuracy. The average height differences were similar; however, the spatial distribution varied between the two clouds. The model from the winter flight campaign had more evenly distributed deviations and overall was better for modelling the CHKS.

Mountain ecosystems, especially those at the highest altitudes, are sensitive to current climate change. Proxy archives may provide an insightful tool to better understand ongoing changes and evaluate future scenarios. Trees have traditionally been used as such archives, as they often respond sensitively to environmental change. Thus, we studied tree-ring records of forest-line species Abies densa Griff. growing in the Eastern Himalayas, central Bhutan, to evaluate the effect of climate on the growth of this species. The annual chronologies were generated using standard dendrochronological methods and then compared with climatic data from the CRU TS database. The results demonstrate a negative effect of summer temperatures on the width of the annual rings, suggesting possible stress caused by higher temperatures during the monsoon season. On the other hand, a positive effect of temperatures on tree growth was observed during late winter months. The response to rainfall was mixed, with a positive effect on growth in November and a negative effect in May and January, suggesting a later onset of the vegetation season. To our knowledge, we present the first dendroclimatological study on this long-lived species in central Bhutan, portraying its potential for future climate and environmental research and applications.
