Summary: The study in the Cuenca Mountains in Spain investigated the short-term post-burn tree growth of Pinus nigra and Pinus pinaster, revealing that prescribed burning had minimal impact on tree growth. Stand type and individual tree characteristics were significant factors affecting tree growth. The inclusion of fire severity variables in tree growth models showed that maximum scorch height played a key role in variability of tree growth.

Summary: Retention forestry, specifically green tree retention, has long-term positive effects on avian diversity, even several decades after final felling in conifer dominated production stands. The presence of broadleaf green tree retention can benefit bird assemblages by increasing their abundance, species richness, and supporting important guilds such as broadleaf-associated birds and cavity nesters. However, factors like the number and species composition of retained trees, as well as their environmental context within the stand, may affect the effectiveness of green tree retention.

Summary: This study aimed to investigate the short-term effects of forest gap size on soil enzyme activities in Platycladus orientalis plantations. The results showed that medium and small gaps had significantly higher soil peroxidase activity in April and October, respectively, at the outside position compared to no gaps. Additionally, large gaps had significantly higher soil dehydrogenase activity in April at the outside position compared to no gaps. Moreover, large and small gaps had significantly higher soil urease activity in July and October, respectively, at the outside position compared to no gaps.

Summary: This study investigated the ecology of climbers and the influence of soil characteristics on diversity, richness, and indicator species distribution in the Changa Manga Forest Plantation, Punjab, Pakistan. A total of 29 climber species were identified, with herbaceous climbers being the dominant life form, showing peak flowering in August and September. Soil factors significantly influenced the diversity and distribution pattern of climbers. The research provides insights into climbing plant ecology in response to soil variables, impacting policy and practice in the Himalayan region and beyond.

Summary: Insect outbreaks have significant effects on forest ecosystems, including changes in soil arthropod communities. This study aimed to understand the effects of forest tent caterpillar outbreaks on ant communities in temperate and boreal forests in Canada. The results showed that outbreak sites had decreased ant species richness and increased evenness in boreal forests, with significant changes in species composition. In the temperate forest, similar but weaker patterns were observed. These findings highlight the importance of disturbances like insect outbreaks in driving changes in ant communities.

Summary: There is growing interest in implementing Continuous Cover Forestry (CCF) to mitigate the negative effects of traditional rotation forestry on biodiversity, although the impacts of CCF on forest growth, yield, and biodiversity are not well understood. This qualitative review compared biodiversity and long-term yield between the selection system (a type of CCF) and traditional rotation forestry in Picea abies-dominated forests. The majority of simulation studies found higher long-term yield in rotation forestry, but the most productive system remains uncertain. Biodiversity comparisons showed differences between clearcuts and stands managed with the selection system, but more research is needed to determine the long-term effects on biodiversity.

The results reveal that average stem size, harvest unit size, and harvesting process are important variables influencing both cost and productivity. Furthermore, tree height and country significantly affect harvesting cost, while machine rate and utilization have a major impact on harvesting productivity. The study provides valuable insights for forestry stakeholders regarding the variance structure of harvesting cost and productivity.

Summary: This study examined the long-term effects of pre-commercial and commercial thinning on the growth of balsam fir and red spruce in spruce-fir forests. The results showed that thinning treatments significantly increased the growth of balsam fir in stands without pre-commercial thinning, while the growth of red spruce was more moderate. In stands with pre-commercial thinning, both species showed similar growth responses. Thinning treatments effectively reduced mean height diameter ratios and improved growth efficiency.

Summary: Stand density management is crucial for achieving diverse silvicultural objectives. Decision-support tools in this domain range from expert opinion to sophisticated computer models. Graphical frameworks like density management diagrams and stocking guides are well established and balance quantitative rigor with user accessibility. Advances in statistical modeling and data availability are overcoming limitations in developing reliable charts, encouraging more widespread use. The adoption of relative density based on stand density index is proposed as a logical metric for linking different formats.

The results showed that the Random Forest algorithm performed better in modeling. The red-edge spectral vegetation indices played a significant role in the estimation of both leaf area index and basal area per ha. These models are important for evaluating the dynamics of the eastern spruce budworm, as red spruce and balsam fir are its primary host species.

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.

Through soil charcoal analysis in the Lorraine Plateau in France, the presence of Fagus and Quercus in mature Quercus stands was confirmed.

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.
