Summary: Widespread forest mortality has been observed in recent years, possibly due to changes in forest water content. This study explored the dynamics of forest water content in boreal forests based on remote sensing data and found a declining trend from 1988 to 2016. The study also revealed a strong negative correlation between atmospheric water demand and forest water content, with a greater decline in areas with higher water demand.

Summary: The study developed a spatially-distributed nutrient balance model which can help forest managers identify current and future nutrient export hot spots and compare different logging scenarios. Results show that the model can effectively assess the impact of logging on nutrient export and find suitable scenarios that balance wood supply and acceptable levels of nutrient export.

Summary: The study found that continuous cover forestry can reduce pollutant concentrations and CO2 emissions from boreal peatlands, providing better environmental protection for inland waters.

Summary: This study combines clustering and classification methods to investigate the regional patterns and drivers of total nitrogen trends in the Chesapeake Bay Non-Tidal Monitoring Network. Results show that improved agricultural nutrient management has led to declines in agricultural nonpoint sources and water-quality improvement. The developed models are also used to predict fine spatial information for the entire Chesapeake Bay watershed, facilitating targeted watershed management.

Summary: This study investigated the impact of forest clear-cutting on nitrogen and phosphorous export in water systems, finding that the location of clear-cuts had different effects on nutrient export and only 5% of the forest area could contribute to half of the total export. A conceptual planning framework was proposed based on the findings to identify areas with high nutrient export, aiming to improve the effectiveness of water protection measures in forestry.

Summary: The research shows that aquatic carbon emissions in boreal Quebec vary with the average slope of the watershed, rather than the size of the watershed or the total surface area of aquatic systems. These emissions could offset terrestrial carbon sinks by as much as 38% in boreal Quebec, highlighting the significant impact of aquatic systems on the carbon budget in this region.

Summary: The study highlights the significant influence of soil characteristics on a soil's sensitivity to increased forest biomass harvesting in the long term. Different types of soil respond differently to whole-tree harvesting and stem-only harvesting, with site productivity being lower after whole-tree harvesting in two coarse-textured granitic soil provinces.

Summary: Balancing clean water and economic growth remains a challenge for achieving the Sustainable Development Goals (SDGs) set by the United Nations. This study proposes a new watershed management framework (WAM-SDGs) that integrates water quality impacts and cost-effectiveness analysis of catchment actions. The method was tested in two catchments in China, showing improved cost-effectiveness and reliability compared to traditional methods. Priority should be given to urban catchments for water quality improvement, while agricultural catchments are more cost-effective.

Summary: The global forest carbon stock is mainly found in soil organic matter and understanding the effects of forest management practices on soil carbon stocks and greenhouse gas emissions is crucial for effective climate change mitigation strategies. This study synthesized literature on forest management practices that increase soil carbon stocks and reduce greenhouse gas emissions. Soil processes, such as nitrogen fertilization and peatland hydrology management, play a significant role in soil greenhouse gas balance.

Summary: Global concern over water quality, demonstrated by UN Sustainable Development Goals, has led to a case study focusing on the Piabanha River rehabilitation. The main issue identified in the watershed is sanitation, particularly in urbanized regions and during dry seasons with low river flows. Through computational modeling, reductions in organic load have been suggested in certain sub-basins to improve water quality.

Summary: In this paper, the process of browning in boreal lakes surrounded by managed forests and wetlands is reviewed, and the ecological consequences and ecosystem-based management of browning are discussed. Survey data on public perceptions of water quality in Finland are presented to understand the impact of browning on recreational fishing tourism. The need to go beyond the EU's Water Framework Directive and improve understanding of microbial processes within lakes is highlighted.

Summary: Natural disturbance-based management (NDBM) aims to preserve specific structural and compositional attributes of natural forests in managed stands. The Sylvicul-ture et Amenagement Forestier ecosystemique (SAFE) project in northwestern Quebec, Canada has evaluated the potential of NDBM in hardwood, mixedwood, and coniferous stands. The results confirmed that partial harvesting (PC) can maintain stands with mixed structure and composition, complementing clearcuts (CC) as a management option.

Summary: Previous studies have shown that the impacts of harvest on stream chemistry in deciduous forests with seasonal snow cover vary and may take different recovery times. In this study, we investigated the interactive effects of forest harvesting with regional and global environmental changes on stream solute concentrations and other parameters. The results showed that the impacts of harvest on stream chemistry were greatest in clearcut areas, moderate in selection cut areas, and least in shelterwood cut areas. The impacts typically lasted for one to six years, although some solutes were impacted for the entire 21 year post-harvest period. Different solutes showed different response patterns, which were consistent with expected changes in nutrient demand, sources, and transport due to harvesting. Comparing harvest impacts to long-term climate change and acidification recovery revealed antagonistic or synergistic effects depending on the solute. These findings highlight the importance of long-term monitoring to accurately understand the consequences of forest harvesting practices in the face of environmental change.

Summary: Mercury is a widespread contaminant that poses risks to wildlife and human health. This study focuses on boreal forests and quantifies factors influencing mercury export from these areas. The research shows that mercury concentrations are relatively low, but there are significant differences in mercury export. Coniferous forest cover is an important predictor of mercury loads, and wet forest cover can be used as an effective alternative metric.

Summary: This study investigated the effects of different slash loadings and treatments on soil physical, chemical, and biological processes. The findings suggest that retaining moderate amounts of slash can maintain a suitable balance of soil conditions for promoting forest regeneration.
