Selection cutting, a key method within CCF, presents unique challenges for forest growth modelling due to its complex structure and distinct growth dynamics.

This study assessed the short-term (i.e., up to 15 years) predictive accuracy of the Swedish Heureka Decision Support System for stands managed with selection cutting. It assessed growth models for tree recruitment, growth, and mortality using data from 27 CCF field experiments covering a broad latitudinal and environmental range across Sweden. A linear mixed-effects modelling approach was used to analyse differences between observations and model predictions. Findings revealed potential species-specific biases, with an average underestimation of volume growth by 2 m³ ha⁻¹ yr⁻¹ after ten years of simulation, driven predominantly by underestimations in Norway spruce growth. While mortality predictions were generally accurate, they exhibited slight underestimation after recent cutting and overestimation otherwise. Ingrowth density predictions demonstrated minor biases, with spruce being underestimated and birch overestimated, but displayed high residual variability. Sensitivity analysis revealed correlations of residuals with stand variables, including site index, proportion of spruce, and stand basal area. The study faced limitations due to data scarcity and the short observation periods. Although most observed biases were not statistically significant, the findings underscore potential discrepancies when applying current Swedish models to selection cutting stands.</div></div>","PeriodicalId":12350,"journal":{"name":"Forest Ecology and Management","volume":"582 ","pages":"Article 122560"},"PeriodicalIF":3.7,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143445673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is unclear whether forest AGB is also regulated by the varying proportions of dominant species within a community. Based on nine relative density gradients (10 % - 90 %) of <em>Quercus aliena</em> var. <em>acutiserrata</em> populations, this study explored the spatial pattern in forest AGB and the underpinning drivers using generalized linear mixed models (GLMM) and structural equation modeling (SEM). Our results showed that as relative density of the dominant oak species increases, the community AGB, soil nutrients, intraspecific competition intensity and evolution diversity significantly increased, whereas tree species diversity, intraspecific and interspecific diameter at breast height (DBH) variation and interspecific competition intensity all significantly decreased. Soil nutrients could exert an important positive effect on forest AGB accumulation by mediating tree species diversity (Simpson index) and interspecific exclusion stress (interspecific DBH variation and competition intensity). Species diversity and interspecific DBH variation had negative impact whereas the interspecific competition intensity exerted positive contribution on forest AGB. We found that the density-dependent selection effect may be the fundamental cause of biodiversity loss and aboveground biomass accumulation, which highlights the significant influence of dominant species density on community development.

We simulated litter conditions that pine seeds may encounter along the edges of invasive pine-dominated areas, including post-fire scenarios. We examined the response of <em>Pinus radiata</em> seed viability to the combined effects of litter origin (native forest <em>vs</em>. pine-invaded forest), litter burn status (burned litter residue <em>vs</em>. unburned litter), and time since deposition in the field (4 months, 1 year, and 2 years). Burned litter generally reduced viability, though the effect was less pronounced in native litter than in pine forest litter. <em>Pinus radiata</em> seeds remained viable for at least one year in burned forest substrates, indicating that forests affected by fires are highly vulnerable to pine invasion. Burned litter residue, particularly from pine, promoted germination shortly after seeds were left in the field (pine litter: 30 % ± 1.4 <em>vs</em>. native litter: 17 % ± 1.1), compared to no germination in unburned litter, suggesting that burning accelerates pine colonization. The differing impacts of burned litter from different habitats on seed viability and germination emphasize that microcontext influences on regeneration are specific to each reproductive process.

Lastly, deadwood VCF appears systematically lower than that in live wood, indicating that live wood VCFs may not be good approximators of the VCF in deadwood. Our results suggest that failing to account for the VCF of deadwood in forest C estimation studies, especially in the early stages of decay, results in errors in deadwood C stock estimates of ∼0.9 % on average.

Accurately capturing masting variability is important for effective forest management, conservation efforts, and predicting ecosystem responses to environmental changes. The adoption of low-cost methods facilitates the large-scale data acquisition needed in this time of unprecedented environmental upheaval, but it is important to understand the reliability of such methods. We investigated the relationship between the timed count method and the quadrat-based method for monitoring seed production in European beech (<em>Fagus sylvatica</em>). The timed count method is fast, cost-effective, and suitable for areas with public access. These characteristics make time counts a practical choice for large-scale seed monitoring. However, the method has not been cross-calibrated with more traditional ground-based methods like quadrat sampling, which involves exhaustive seed collection from designated plots under tree canopies. Our research reveals a loglinear relationship between seed counts obtained by the two methods, and shows that the timed count is an effective method of estimating seed production. We also found that seed production exhibits greater dispersion in patchiness at lower levels of seed fall, which explains why the timed count method, covering a larger area, captures greater variability in seed fall compared to the quadrat method in such contexts. This highlights the importance of choosing an appropriate sampling strategy to accurately assess seed fall. The differences between the two methods introduce variability into derived masting metrics, such as the coefficient of variation and synchrony, with individual-level seed production variability metrics being more affected than population-level ones. The findings underscore the importance of understanding how different sampling methods can impact long-term ecological studies, particularly those focused on masting behaviour.</div></div>","PeriodicalId":12350,"journal":{"name":"Forest Ecology and Management","volume":"581 ","pages":"Article 122551"},"PeriodicalIF":3.7,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143395611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 1st IUFRO Wind and Trees Conference was held in 1993 in Edinburgh, Scotland and this latest publication allows us to reflect on how the subject has developed over the last 30 years. Familiar themes continue to be important including the interaction between trees and forests and the wind, and predicting the risk of damage to forests and trees. However, there has been an increased awareness of the importance of wind disturbance in shaping the ecology of many forests including broadleaf forests and forests in tropical and subtropical regions. Furthermore, there is now more emphasis on trying to understand the response of individual trees to the wind and together with the increased research on wind impacts on broadleaved trees this is allowing a better understanding of the risk that urban trees, trees in rural landscapes, and mixed species forests are facing. A new development has been the emergence of clear evidence of genetic differences in the wind resistance of different clones of the same species. This gives us the opportunity to breed trees with greater resistance to wind damage. At the same time a paper in this special issue shows that Scots pine (<em>Pinus sylvestris</em>) trees across Europe adjusted their wind resistance to the local wind environment, demonstrating the high plasticity of this and other tree species. Understanding the interaction of genetics and environmental influences on tree resistance to wind remains a major challenge for future research. Further challenges are to develop a better understanding of tree dynamics, root fatiguing, and the interaction of roots, soil and moisture. It is clear that we need to take a holistic view of forest disturbance by understanding the interaction of wind with other disturbance agents such as drought, bark beetles, and fire. In this way we can hopefully help to develop forest ecosystems that are more resilient to our future climate.</div></div>","PeriodicalId":12350,"journal":{"name":"Forest Ecology and Management","volume":"581 ","pages":"Article 122556"},"PeriodicalIF":3.7,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143395608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
