This document is a part of a long-running Levels-of-Growing-Stock (LOGS) Cooperative Study in Douglas-fir stands, specifically detailing findings from installations at Sayward Forest and Shawnigan Lake in British Columbia. The core objective of the LOGS study is to understand how different thinning intensities impact cumulative wood production, individual tree size, and growth ratios in young Douglas-fir stands. This progress report summarizes data from these two Canadian sites, showing that volume growth is strongly tied to the amount of growing stock retained, and that thinning significantly influences tree size distribution and live crown development, suggesting potential for future productivity gains. The study also offers comparisons between various thinning regimes and unthhinned control plots, revealing the long-term implications of silvicultural practices on forest stands.

This document delves into the critical aspects of aspen silviculture, addressing the increasing complexity of managing aspen forests due to greater utilization and evolving approaches to mixedwood management. The authors review the mechanisms of aspen regeneration, both through root suckering and seeds, and offer preliminary guidelines for managing the density of aspen stands in their early development. The paper aims to synthesize existing knowledge and identify knowledge gaps to better inform management decisions aimed at achieving various forest composition objectives.

This paper presents a comprehensive analysis of various strategies to reduce greenhouse gas emissions within British Columbia's forestry sector. The study uses a systems perspective, evaluating the impact of different forest management and wood utilization practices not only on forest ecosystems but also on harvested wood products and the potential for wood to substitute for more emission-intensive materials. By quantifying GHG reductions alongside economic, socio-economic, and environmental consequences, the authors aim to provide an integrated framework for decision-makers to understand trade-offs and plan for long-term climate change mitigation in the land sector.

This paper investigates the interplay between future wildfire risk and the greenhouse gas mitigation potential of rehabilitating forests in British Columbia, Canada. Using modeling that simulates future fire scenarios and tracks carbon in forests and harvested wood products, the study assesses whether post-fire salvage logging and replanting can lead to a net reduction in GHG emissions compared to natural regeneration. The authors explore the conditions under which these rehabilitation efforts yield climate benefits and compare this potential mitigation against the substantial GHG emissions from the projected increase in wildfires, questioning if resources might be better directed towards preventing fires in the first place.
