Summary: The sustainable management of highly productive eucalypt plantations requires the use of fertilizers to balance nutrient exports. Our study aimed to assess the impact of management practices in these plantations on nutrient losses through deep leaching. We found that while concentrations of certain ions increased significantly after clear-cutting and fertilizer application, leaching fluxes remained relatively low throughout the rotation.

Summary: Nutrient resorption efficiency changes with stand development, with certain nutrients increasing and others decreasing with stand age. Needle nutrient concentrations and ratios also show different patterns between green and senesced needles as stand age increases. Nutrient resorption efficiency is correlated with nutrient concentrations and ratios, playing a role in tree growth and development along the plantation chronosequence.

Summary: This study focused on the effects of harvesting residue removal practices and repeated fertiliser addition on selected wood quality attributes. It found that different levels of harvest removal had little to no effect on wood quality measures, but repeated fertiliser addition throughout the rotation could negatively impact wood density, stiffness, branch size, and heartwood content. The impact on forest growers and end-product performance will depend on the market segment logs are sold into, suggesting a need for nutritional strategies that consider potential adverse impacts on wood quality.

Summary: This study observed the effects of alder retention on the growth of lodgepole pine in a logged area in British Columbia, Canada. The results showed that alder retention had modest reductions on the height and diameter increment of lodgepole pine, and its effects on soil nitrogen were limited to the forest floor organic horizons. The nutritional benefits of alder retention for lodgepole pine were no longer detected after 6 years. These findings suggest that limited intervention to control Sitka alder in similar stands is justified.

Summary: Saginaw Forest in Ann Arbor, Michigan is the second-oldest eastern white pine plantation in the United States, which has conducted pioneering thinning experiments. Despite no silvicultural treatments occurring for several decades, the previous thinning treatments still have effects on the current tree growth. Management efforts should focus on controlling invasive species and hardwood ingrowth, as well as regenerating native tree species to preserve this important cultural and historical landmark.

Summary: This study investigated the carbon and macronutrient cycling in cocoa and teak plantations in Central-West Cote d'Ivoire, revealing that cocoa plantations had lower inputs of carbon and nitrogen compared to the forest, while teak plantations had similar phosphorus inputs and greater potassium inputs. Cocoa leaf litter decomposed at a rate similar to the forest but faster than teak, with significant declines in soil carbon mineralization rate and mineral nitrogen concentration observed in both tree plantations. Teak was identified as a good candidate for shade to compensate for the deficit in carbon and nitrogen inputs exhibited by cocoa relative to the forest.

Summary: This review paper summarizes the application of hyperspectral remote sensing in vegetation assessment, particularly in the detection of foliar nutrients. The study found that near-infrared technology can provide reasonably accurate results by utilizing appropriate preprocessing data methods and statistical models that reduce spectral noise. However, sample sizes, latent variables, and leaf water content are the main factors affecting the outcomes. Further research is needed to understand the effects of epicuticle wax and trichomes on leaf optical properties.

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: 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.
