This extension note details the Prince George Small Streams Project, an initiative launched to evaluate the effectiveness of policies aimed at protecting the riparian functions and fish habitat values of small streams. The study assessed how a minimum riparian retention prescription impacted various stream characteristics. While the policy successfully met four of its five management objectives, it ultimately failed to maintain overall fish habitat values, particularly concerning the long-term supply of large woody debris, a significant decrease in litter fall, and an increase in stream temperatures due to reduced shade. Therefore, the authors recommend retaining all trees within 10 meters of the stream bank to better achieve desired environmental outcomes.

This document presents a synoptic assessment of stream and riparian conditions in the Bowron River watershed, conducted 20-30 years after extensive salvage logging. The study investigates the long-term impacts of harvesting, prompted by a spruce beetle outbreak in the 1970s and 80s, on stream health and surrounding riparian areas, which are crucial for ecological balance. Using the Routine Riparian Effectiveness Evaluation, the assessment compares current conditions to historical watershed assessment procedure rankings, revealing that while some recovery has occurred, the lack of mature vegetation in riparian zones continues to significantly impact stream characteristics, particularly the supply of large woody debris whcih is vital for stream morphology and fish habitat. The authors conclude by offering guidance statements to improve forest management practices, emphasizing the importance of riparian buffers, proper road deactivation, and minimizing soil compaction to mitigate ongoing adverse effects.

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.

This study investigates how commercial thinning impacts the growth, yield, and mortality of natural lodgepole pine forests in Alberta, Canada. Faced with a predicted timber shortage due to fires and mountain pine beetle infestations, the research explores thinning as a strategy to increase mid-term sawlog supply by accelerating tree growth and enabling earlier timber access. The findings reveal that while thinned stands initially show less volume, they ultimately demonstrate a greater cumulative volume gain when factoring in the wood removed during thinning. This benefit stems from increased individual tree diameter and live crown ratio for remaining trees and a significant reduction in overall tree mortality, particularly among smaller trees.

This technical report explores the viability of commercial thinning as a forest management strategy within the Arrow and Cranbrook Timber Supply Areas of British Columbia. The primary goal was to investigate if commercial thinning could help offset projected wood supply reductions resulting from new forest policies and land-use plans. The study involved a multi-stage methodology: identifying potential forest stands using Geographic Information Systems theming, conducting field inventories and reconnaissance surveys to assess suitability, and modeling the impact of thinning on wood flow. While the project successfully identified potential thinning volumes, it also highlighted significant challenges such as limited road access, unsuitable stand structures, and the need to balance timber extraction with other resource management objectives.

This document on the 26-year assessment of the Montane Alternative Silvicultural Systems study focuses on natural regeneration and understory species within various managed forest environments. The MASS study is highly structured, comparing distinct silvicultural systems such as clearcut, shelterwood, and old growth by utilizing three separate replicates for each treatment type.

This paper presents the long-term ecological effects of forest fuel and restoration treatments from the ongoing national Fire and Fire Surrogate study, analyzing data collected over approximately 20 years across four diverse sites in the Western and Eastern United States. The central goal of the original FFS study was to evaluate how mechanical treatments and prescribed fire impact forest ecosystems by reducing fire hazard, promoting desirable fire-adapted species, and improving understory diversity. Key findings reveal that the most effective treatment varies significantly by region: mechanical treatments combined with fire yielded better long-term outcomes in Western pine-dominated forests, while prescribed burning alone proved more beneficial in Eastern hardwood-dominated forests. The authors conclude that to maintain these desirable conditions and achieve long-term resilience, treatments must be adapted to the specific ecosystem and followed up with repeated applications.
