This document provides guidance on how to conduct salvage harvesting in areas affected by the mountain pine beetle in the Southern Interior Forest Region of British Columbia while maintaining habitat structure and wildlife diversity. It emphasizes that salvage logging, while economically important, can negatively impact ecosystems already disturbed by beetles. The core idea is to use within-stand retention practices like leaving live trees, snags, and downed wood, along with strategically placed partial harvesting, to mimic natural disturbance patterns and create habitats that support a variety of species and aid forest recovery. The report discusses five key issues to consider: loss of mature forest attributes, connectivity, riparian areas, access management, and habitat homogenization, offering strategies to address them.

This document details the SADO management system, a conservation-focused approach specifically designed for sustaining old-growth characteristics in aspen, birch, and cottonwood forests within British Columbia's SBS zone. Recognizing the relatively short lifespan and successional vulnerability of these deciduous stands, the system provides a step-by-step guide for forest managers. Its core principles revolve around monitoring regeneration, selectively removing conifers, managing herbivore browsing, ensuring adequate light, and addressing regeneration capacity to promote the development of self-sustaining, all-aged stand structures that continuously exhibit old-growth attributes, with a particular emphasis on maintaining ecological values and biodiversity.

This document explores the impact of broadleaf cover, specifically aspen stands, on the size of wildfires in British Columbia.

This document reviews existing research on the relationship between aspen forests and wildfire, particularly in the context of British Columbia. It explores aspen's inherent fire-resistant characteristics, such as high moisture content and unique regeneration, which contribute to reduced wildfire spread and intensity. The document examines the potential for utilizing aspen in wildfire management strategies, including as natural fuel breaks, while also acknowledging conditions like drought that can compromise this resilience. The author identifies knowledge gaps and suggests preliminary strategies for promoting and managing aspen to mitigate future wildfire risk in a changing climate.

This paper investigates the effectiveness of different forest fuel treatments, such as thinning and prescribed burning, in reducing the severity of subsequent wildfires. Leveraging a unique 1200-hectare experiment that was later impacted by a significant wildfire, the authors compared various treatment approaches, including thin-only, burn-only, and a combination of both, against an untreated control. Their analysis of fire severity metrics, considering pre-fire fuel conditions and fire weather, provides strong evidence that proactive fuel management, especially combining thinning and burning, significantly mitigates wildfire intensity and damage to trees, even decades after the treatments were implemented and under a range of weather conditions. The study supports the continued use of these treatments as valuable tools for forest restoration and enhancing resilience to increasingly severe wildfires.

This paper explores the opportunities and limitations of forest thinning as a strategy to enhance the resistance and resilience of trees and forests to global change. The authors reviewed existing literature to assess how thinning impacts forest vulnerability to key stressors like drought, fire, insects and pathogens, and wind. While the study identifies several instances where thinning can be beneficial, particularly in mitigating drought and fire risks, it emphasizes that thinning is not a universal solution and its effectiveness varies depending on the specific stressor, forest type, and management practices. The paper highlights the need for more research, especially in underrepresented regions, to better understand the long-term effects of thinning and to develop effective adaptive forest management strategies in the face of increasing global environmental challenges.

This extension note presents findings from investigations into how the mountain pine beetle infestation and subsequent salvage harvesting near streams impact small stream and riparian zone health in British Columbia's Sub-Boreal Spruce zone. The research focused on understanding the riparian stand structure in these affected areas and assessing the influence of both the beetle infestation and harvesting on riparian zones, particularly shade levels and overall stream function. Through basal area studies and a stream health evaluation protocol, the authors aimed to provide short-term answers to guide forest management practices in regions heavily affected by the mountain pine beetle.

This extension note details a study on windthrow in partially cut lodgepole pine forests in west-central British Columbia. The research was motivated by concerns that partial harvesting, a strategy used to manage habitat for the blue-listed northern caribou, might increase windthrow to levels that negatively impact caribou habitat, timber supply, and forest health. The study compared windthrow rates in different partial cutting methods to uncut control areas over a 5. 3-year post-harvest period to assess the risk of increased windthrow associated with these silvicultural systems.

This paper investigates how diversifying managed forests in British Columbia could enhance their ability to recover from disturbances, specifically a recent mountain pine beetle epidemic linked to climate change. The authors used computer simulations to compare different forest management strategies over an 80-year period, assessing their impact on ecological resilience, timber supply, and economic outcomes. Their findings suggest that a strategy focused on proactively harvesting dominant, susceptible tree species and promoting a greater variety of planted and naturally regenerating trees leads to improved forest health, higher long-term harvest rates, and more stable economic returns without compromising economic viability. The study advocates for incorporating diversification as a key approach to increasing the resilience of managed forests in the face of future environmental challenges.
