This extension note focuses on best management practices for riparian areas following salvage logging after wildfires, aiming to minimize negative impacts on aquatic habitats. It acknowledges that while current regulations permit harvesting fire-damaged timber in riparian zones, this can harm both water and land ecosystems by increasing erosion and reducing crucial large woody debris. The document proposes specific guidelines for managing these sensitive areas based on factors like burn severity and the connection of slopes to streams, striving to balance timber recovery with the protection of vital ecological functions and downstream resources.

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.

Ultimately, the report emphasizes the need for a deliberate and informed decision-making process to select and implement effective adaptation measures, advocating for ongoing monitoring and collaboration among stakeholders.

This paper investigates the long-term effects of post-wildfire logging in dry coniferous forests east of the Cascade Range. It addresses a key debate by presenting findings that post-fire logging effectively reduces future surface woody fuel levels over several decades, thereby potentially mitigating the severity of subsequent wildfires. Furthermore, the research indicates that when best management practices are employed, post-fire logging has minimal lasting negative impacts on the recovery of understory vegetation. The purpose of this publication is to provide scientific information to land managers making decisions about post-fire forest management, particularly regarding fuel reduction and ecological impacts.

This paper investigates the impact of long-term fire suppression on the drought sensitivity of mixed-conifer forests in the Western United States. The study utilizes tree-ring analysis of stable carbon isotopes to demonstrate that the exclusion of frequent, low-severity wildfires has led to overcrowded forest stands. This increased density results in heightened competition for water and nutrients among trees, making them more susceptible to drought stress, insect outbreaks, and disease compared to historically open forests maintained by fire. The findings emphasize the importance of reintroducing fire and managing stand density for forest restoration and increasing resilience to future climate conditions.

This paper analyzes the record-breaking 2023 wildfires in British Columbia, detailing their significant ecological and social impacts, which are seen as the result of a century of altered relationships with fire intensified by climate change. The authors argue for an urgent transformative shift towards coexisting with wildfire, moving beyond suppression to embrace its ecological role and Indigenous stewardship practices. The paper proposes six interrelated strategies to achieve this coexistence: diversifying wildfire response, increasing suppression capacity, mitigating community risk, implementing landscape fire management, transforming wildfire governance, and strengthening expertise. This paper emphasizes the need for a holistic, all-of-society approach involving policy changes, sustained funding, and collaboration to build resilience against future extreme wildfires.
