Summary: Many jurisdictions have proposed guidelines to identify sites at risks of soil degradation during the extraction of logging residues. These guidelines are often based on expert opinion and the precautionary principle due to the lack of clear understanding of site sensitivity to intensive biomass removal. Different indicators assess different processes and aspects of site sensitivity, suggesting the need for indicators based on long-term monitoring results and leaving a substantial proportion of harvest residues on sites evaluated as sensitive.

Summary: Research suggests that integrated systems that produce roundwood and energy chips simultaneously are the most cost-effective for producing energy chips. However, these systems are only feasible on a limited number of sites. Post-harvest chipping, where roundwood is harvested separately from energy chipping, may allow for chips to be produced from a wider range of harvest sites. This study evaluates the feasibility of using post-harvest systems to recover logging residues and non-merchantable stems.

Summary: The increasing global energy requirements and the negative impact of climate change have led researchers to focus on developing cleaner technologies for energy production. Microbial fuel cell (MFC) is an emerging method for generating clean energy. However, the burning of agricultural wastes by farmers in India and other East-Asian nations has caused significant air pollution. Innovative research on MFCs using post-harvest agricultural residue as a feed source could contribute to a cleaner and more sustainable society. This paper provides a summary of such research and discusses the economic and commercial challenges associated with it.

Summary: The input of acidity to Swedish forest soils from forestry activities has shifted over time, with forestry now being the dominant source compared to atmospheric deposition. The increase in standing forest biomass has led to the net uptake of cations, while whole-tree harvesting has had minimal impact on acidity input. The geographical gradient in acid input is reflected in the proportion of acidified soils in Sweden.

Summary: There is a growing societal demand to increase the use of forest biomass for substitution of fossil fuels, but the Critical Biomass Harvesting (CBH) indicator is criticized for not accounting for all relevant processes and exaggerating sensitivity, correlating poorly to actual forest soil conditions. It is suggested that the risk assessment and policy implications for forest biomass harvesting guidelines need to be based on solid scientific methods and data availability may not allow the indicator to be calculated at a high enough spatial resolution for forest management advice.

Summary: Litter decomposition is influenced by environmental factors, substrate quality, microbial communities, and N deposition. Climate impacts on global-scale decomposition are general but become more significant as decomposition progresses, while N deposition effects are litter-specific and significant in certain biomes. Climate changes are expected to increase litter mass loss, while N deposition changes may dampen climate-driven increases in decomposition, depending on biome and substrate stage.

Summary: This study analyzed the effects of site and climate on the self-thinning line in Scots pine forests in Europe. The results showed that species tolerance, temperature, and precipitation influenced the slope of the self-thinning line. In terms of the intercept, latitude and radiation had compensating effects. Time did not show significant trends in the self-thinning line. The study highlights the need to adapt management strategies and models based on self-thinning to different latitudes. Climate change has not yet significantly impacted the self-thinning trajectory, but a continuous rise in temperature and high precipitation may accelerate the self-thinning process and result in increased biomass accumulation.

Summary: Secondary forests play a crucial role in ecosystem dynamics and biodiversity recovery. This study investigated the mechanisms underlying secondary succession in a restored secondary forest and found that deciduous tree species transition from diversity accumulators to repellents as they progress through different life history stages, while evergreen tree species can act as accumulators or remain neutral. The study also revealed the effects of density dependence on the mortality and regeneration of different tree species, and highlighted the importance of early-arriving tree species in facilitating the establishment and diversity of late-arriving counterparts.

Summary: Fagus sylvatica L. is a competitive tree in European temperate deciduous forests, but often sporadic or absent in present-day stands where Quercus spp. are dominant. Through soil charcoal analysis in the Lorraine Plateau in France, the presence of Fagus and Quercus in mature Quercus stands was confirmed. Radiocarbon dating results indicated that historical forest management caused the replacement of Fagus by Quercus, starting from the Bronze Age.

Summary: This study examines the influence of canopy structure on tropical tree growth using data collected through unmanned aerial vehicles (UAVs) and field measurements. The results show that combining UAV and field data can improve the prediction of tree diameter increment. Diameter at breast height and crown area are complementary predictors, and crown-based competition indices significantly enhance prediction models. The calibrated model at one site can accurately predict growth at another site.

Summary: Regeneration failures in the closed-crown boreal forest, resulting in the creation of open lichen woodlands, can be restored through clear-cutting, scarification, and natural seeding. Clear-cutting combined with scarification promotes seedling establishment, and scarification creates suitable microsites for germination. Seedling growth in lichen woodlands is higher when logging and scarification are combined, but lower compared to feather moss stands. Afforestation through natural seeding following scarification could be a cost-effective option for restoring lichen woodlands.
