Summary: Predicting tree growth is essential for understanding the carbon sink role of forests and their ability to mitigate climate change in the short term. This study used large-scale data and mathematical models to forecast tree growth in monospecific forests, demonstrating accurate predictions of tree diameter growth and aboveground tree biomass stocks trends.

Summary: The long-term effects of harvesting on carbon pools in a dry pine forest were assessed, revealing significant impacts on coarse woody debris and soil carbon pools, while live tree carbon pool showed little change. This highlights a tradeoff between harvesting and environmental conservation.

Summary: The continuous decline and degradation of tropical rainforests are mainly driven by land-use change, and climate change will exacerbate the situation. This study investigated the regeneration of woody species in different habitat types along an elevational gradient in Tanzania. It found that natural regeneration of woody species occurs in all disturbed habitat types, indicating the powerful tool of natural regeneration for forest diversity recovery after disturbances.

Summary: This study assessed the uncertainty in tree aboveground live carbon estimates at different scales using small area estimation approaches, guiding users in selecting appropriate scales for application. Results showed that model-assisted estimation was generally supported, except for small areas with limited data for generating accurate estimates. Users should be cautious when interpreting model-based estimates of error, as they may not account for model mis-specification and induced bias.

Summary: Downed woody material (DWM) plays a crucial role in the forest carbon cycle, with diverse carbon drivers and high variability making it difficult to predict. New models developed using nationwide DWM inventory in the US have substantially improved predictions of DWM carbon density at stand level.

Summary: This study provides a comprehensive global-scale assessment of the impact of forest harvest on soil N2O flux. It found that intensive forest harvest significantly increased soil N2O flux, which lasted for approximately six years. The effect of forest type and time since harvest on soil N2O flux were also identified.

Summary: This study proposes an integrated methodology to estimate changes in forest carbon pools at the level of forest stands by combining field measurements and ALS data. The results demonstrate that ALS data can be used indirectly through a chain of models to estimate soil carbon changes at the primary level of forest management.

Summary: The study compared FAS and LIS methods for estimating volume or biomass of fine woody debris (FWD), and found LIS to be more efficient. Diameter measurement was identified as the main source of error, while wood density measurements could be simplified without much impact on accuracy. The length and number of transects were also found to greatly influence the estimates.

Summary: Statistical confidence in estimates of timber volume, carbon storage, and other forest attributes is influenced by uncertainty in field measurements. This study compared measurements made by field crews and quality assurance crews in the US Forest Service's Forest Inventory and Analysis program. The results showed that measurement uncertainty is generally small, but higher for certain variables requiring judgment. Uncertainties in basal area, timber volume, and aboveground biomass were negligible when scaled up to larger areas. Understanding sources of uncertainty is important for forest monitoring, inventory management, and policy decision making.

Summary: The Atlantic Forest is highly threatened, leading to fragmented and heterogeneous landscapes. This study utilized remote sensing to estimate the carbon stock in different successional stages of the forest, finding significant variations. High-resolution multispectral data performed best in the rainy season.

Summary: This study examined the annual basal area growth and mean height of Scots pine and Norway spruce in Swedish forests from 1983 to 2020. The results showed a significant increase in mean height at a given age for both species, while the annual basal area growth remained stable. The findings suggest that trees in Swedish forests have become taller and slenderer over time.

Summary: This study examined the main factors contributing to the CFP of 33 Italian wines and compared the results obtained using full inventory data versus a simplified model. Key contributors to GHG emissions include glass bottles, electricity use in the winery stage, transport of final products, heat use in the winery phase, and fossil fuels used in vineyards.

Summary: Analyzing tree size-density dynamics in the past 20 years in the US forests, it is found that while the forest land area remains stable, timber volume and tree biomass have greatly increased. 90% of US forest land has reached a biologically-relevant density threshold, particularly in areas prone to future drought conditions.

Summary: Live woody vegetation is the largest reservoir of biomass carbon, with its restoration considered one of the most effective natural climate solutions. Although live biomass is responsible for more than 80% of gross terrestrial fluxes, gross emissions and removals in the tropics were four times larger than temperate and boreal ecosystems combined.

Summary: The study found that total biomass stocks of downed dead wood, standing dead, and live trees all increased, with large live trees contributing to biomass accumulation and smaller sized down dead wood also increasing. There was a significant positive skew of biomass change across all components and size classes, indicating the impact of severe but episodic disturbance events in providing substantial biomass inputs to standing dead and downed dead wood pools with long-lasting effects. Overall, the incorporation of dead wood-focused analytics into broader forest carbon and biomass monitoring efforts is essential in light of future global change and the importance of maintaining the terrestrial forest carbon pool.

Summary: Species distribution models predict shifts in forest habitat in response to warming temperatures associated with climate change, but actual tree migration rates lag behind, resulting in misalignment of current species with future climate conditions. Forest adaptation strategies involving deliberate adjustments in species composition by planting climate-suitable species have been proposed, but practical evaluations are limited, especially in relation to ecological memory and extreme climate events.

Summary: The study found that the relationship between tree species richness and aboveground productivity shows a unimodal response in grasslands but to a lesser extent in forests. Increasing species richness can lead to higher carbon stocks in forests but does not necessarily result in higher timber volume production. Different factors, such as abiotic factors and management regimes, may influence this relationship.

Summary: This study analyzed two decades of forest plot data in the Great Lakes region of the eastern U.S. and found that shifts in forest communities have important implications for carbon dynamics. The carbon content of live trees varied with different communities, while the carbon content of standing dead trees was influenced by community composition and stand structure.

Summary: Global change drivers have an impact on tree survival and development, especially during the early stages of growth. By analyzing forest inventory plots, it was found that the survival rate of seedlings is influenced by environmental and ecological factors. The results suggest that a comprehensive understanding of the complex and interacting effects on seedling survival is important for predicting and managing successful tree recruitment and future canopy tree composition.
