“…In this study, the results indicated a decrease in the rate of growth of both the aboveground and belowground biomass; this finding could be linked to a decrease in the forest sequestration capacity from forest age as well as the changes in growth rates due to the climate responses [51,52]. In addition, the activity of microorganisms in the soil may be attributed to the climate-related changes in the regional precipitation and humidity [53,54].…”

Forests play a crucial role in South Korea’s carbon neutrality goal and require sustainable management strategies to overcome age-class imbalances. The Generic Carbon Budget Model (GCBM) offers a spatially explicit approach to simulate carbon dynamics at a regional scale. In this study, we utilized the GCBM to analyze the carbon budget of forests in South Korea and produce spatiotemporal maps for distribution of the forest biomass. The growth parameters of five representative tree species (Pinus densiflora Siebold & Zucc., Larix kaempferi Carr., Pinus koraiensis Siebold & Zucc., Quercus mongolica Fisch. ex Ledeb., Quercus variabilis Blume), which are the main species in South Korea, were used to operate the model. In addition, spatial data for harvest and thinning management activities were used to analyze the effects of anthropogenic activities. In 2020, the aboveground and belowground biomass were 112.98 and 22.84 tC ha−1, and the net primary productivity was 8.30 tC ha−1 year−1. These results were verified using comparison with statistics, a literature review, and MODIS NPP. In particular, broadleaf is higher than conifer forest in net primary production. The Canadian GCBM with Korean forest inventory data and yield curves successfully estimated the aboveground and belowground biomass of forests in South Korea. Our study demonstrates that these estimates can be mapped in detail, thereby supporting decision-makers and stakeholders in analyzing the carbon budget of the forests in South Korea and developing novel schemes that can serve regional and national aims related to forest management, wood utilization, and ecological preservation. Further studies are needed to improve the initialization of dead organic matter pools, given the large-scale afforestation efforts in recent decades that have established South Korea’s forests on predominantly non-forest sites.

Forestry is an important component of Canada’s economy with British Columbia (BC) contributing almost half to the national roundwood production. Yet, the country’s timber supply and forest economy are threatened by climate change, with increased frequency and severity of natural disturbances and changes in forest productivity. Mountain pine beetle ( Dendroctonus ponderosae) outbreaks are endemic in BC, but the latest climate change-driven outbreak has resulted in a cumulative loss of over half of all merchantable pine, leading to a mid-term timber supply shortage. In this study, we investigate the potential of commercial thinning and alternative planting regimes based on species diversification and assisted species migration to mitigate the anticipated decrease in timber supply in BC. We simulated the long-term effects of these management options in a case study area in interior BC, using a toolbox that combines management- and research-oriented data and models. We found that combining commercial thinning and species diversification has the best potential to mitigate future timber supply shortages in BC. We discuss the limits of this toolbox approach and identify research needs and recommendations for future studies aiming at modelling cumulative effects of management, climate change, and natural disturbances on timber supply.

In 2012 <i>A Blueprint for Forest Carbon Science in Canada:2012–2020</i> was published to guide policy and research and to support Canada’s obligations for climate change mitigation and adaptation, sustainable forest management, and international reporting. Over the past decade, the body of scientific research focused on forest carbon dynamics in Canada has significantly evolved, providing crucial insights into the intricate interplay between various forest ecosystems and the global carbon cycle. This comprehensive review synthesizes key findings from this period, highlighting improvements to Canada’s estimates of current forest greenhouse gas emissions and removals, the effects of global changes on Canada’s future forest carbon, and forest contributions to mitigate climate change. Collaborating with the forest carbon science community, we identified 426 peer-reviewed published articles on landscape-scale forest carbon research for Canada from 2012 to 2021. The review emphasizes anthropogenic influences and natural disturbances in contemporary GHG emissions and removals for managed forests in the national GHG inventory, highlights the existing dichotomy between management and research models, and stresses the need for integrating disturbance and climate effects for comprehensive GHG estimates. Despite significant progress in estimating and tracking forest carbon using modelled, remotely sensed and ground-based observations, challenges remain in reducing uncertainties, particularly regarding climate impacts on forest growth, decay, and disturbances. Furthermore, the review showcases recent advancements in climate change mitigation strategies and the use of a systems approach that includes forest ecosystem emissions and removals, wood product emissions and substitution benefits of avoided fossil emissions. Through comprehensive scenario analyses, the review underscores regional variations in assessing GHG reductions and notes a shift towards a more holistic approach that considers environmental, economic, and social values. By providing a nuanced understanding of the complexities underlying forest carbon dynamics in Canada, this review sets the stage for future research and policy initiatives aimed at fostering sustainable forest management practices and mitigating the impact of climate change on these vital ecosystems.
