This paper investigates the differential ecological impacts of an extreme 2017 wildfire versus ongoing prescribed burns in Waterton Lakes National Park, AB. The core objective is to understand how reintroducing historical land-use processes, particularly through Traditional Ecological Knowledge, can enhance ecosystem resilience against modern stressors like climate change and invasive species. The study focuses on the Kenow wildfire's high-severity effects on a native-grass prairie compared to lower-severity prescribed burns, suggesting that while prescribed burning is beneficial, incorporating the full historical eco-cultural context, including the role of free-ranging bison and late-season Indigenous burning practices, is crucial for effective ecological restoration. The authors conclude that extreme disturbance is not necessarily catastrophic and that combining TEK with adaptive co-management can create landscapes more resilient to pervasive change.

This document investigates how partial harvesting strategies, designed to enhance mule deer habitat and allow timber extraction in British Columbia's dry Douglas-fir forests, impact complex interactions with natural disturbances like insect outbreaks and wildfires. The study, spanning 30 years, found that while short-term harvesting altered forest structure and reduced the immediate risk of crown fires and Douglas-fir beetle infestations, many of these structural and susceptibility changes reverted over the long term. The removal of harvesting residuals proved more significant in mitigating long-term disturbance risks, particularly for Douglas-fir beetles and intense surface fires, than the time elapsed since the treatment itself. The authors conclude that sustainable forest management integrating timber extraction and mule deer habitat conservation is achievable if partial harvesting occurs at intervals of 30 years or less and residuals are promptly cleared.

This paper introduces walking on two legs, an Indigenous framework for ecosystem restoration and reconciliation in fire-adapted landscapes, particularly in Western Canada. The concept advocates for balancing Indigenous knowledges with Western scientific knowledge, ensuring that Indigenous perspectives and stewardship ethics guide the interconnected processes of restoration and reconciliation. The authors argue that genuine reconciliation requires Indigenous-led restoration of lands, knowledges, and cultures, moving beyond simply integrating Indigenous knowledge into existing Western frameworks. This approach aims to rebuild respectful relationships between people and the land, addressing the legacies of colonialism and revitalizing Indigenous practices like fire stewardship.

This paper highlights the crucial role of boundary spanners in addressing the escalating challenge of wildfires in Western Canada. These individuals and organizations bridge critical gaps, spanning different knowledge systems, organizations, and geographical areas, to foster collaboration and implement proactive fire management strategies, such as cultural and prescribed burning. The authors emphasize that despite the vital work of boundary spanners in building trust, sharing knowledge, and developing capacity, their contributions are often undervalued and lack sufficient institutional support. The piece concludes by asserting the urgent need for dedicated investment in boundary spanning roles to effectively integrate diverse expertise and facilitate collaborative, equitable solutions for wildfire management.

This report compiles over 80 years of fire research to explain how human interventions have altered natural fire regimes, particularly in dry Western U. S. forests. The document emphasizes that accumulated fuels and dense forest structures, a departure from historical conditions, lead to more intense and severe wildfires, posing risks to both ecosystems and human communities. It details various fuel treatments, such as thinning and prescribed fire, as crucial strategies for restoring fire-resilient forests by reducing surface, ladder, and crown fuels. The report advocates for a landscape-level approach to fuel management, acknowledging that while models and observations inform these efforts, uncertainties remain in predicting exact fire behavior.

This paper reviews the effectiveness of stand-level fuel reduction treatments in Canadian boreal conifer forests, specifically focusing on black spruce, jack pine, and lodgepole pine. These treatments, which involve thinning trees, pruning lower branches, and removing understory vegetation, aim to mitigate the risk of fast-spreading, high-intensity crown fires that are naturally prevalent in these ecosystems. While these fuel treatments generally reduce modeled and observed fire behavior under low to moderate fire weather, evidence suggests they become ineffective under very high or extreme fire conditions, especially when combined with high surface fuel loads and the relatively short stature of boreal conifers. The authors highlight the need for further research into managing surface fuel loads, exploring alternative fuel configurations, and integrating these treatments with broader fire suppression strategies.

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.

This presentation focuses on managing forests for resilience as a crucial method for achieving both forest sustainability and value.

Through case studies and management principles, it demonstrates practical ways to enhance forest resilience at various spatial scales, acknowledging the inherent trade-offs in managing for future uncertainties like fire, insects, drought, and climate change.

This study investigates different methods for assessing the effects of controlled burning in a harvested forest area. The study compares the utility of satellite imagery, fire behavior modeling, unmanned aerial vehicle image analysis, and ground-based measurements in evaluating burn severity, fuel consumption, and impacts on surface conditions and vegetation. The report aims to identify accurate and efficient techniques for understanding and managing the ecological consequences of broadcast burning for land management purposes.

This paper synthesizes the disparate groundwater responses to wildfire, noting that post-fire effects range from significant increases to decreases in water fluxes like recharge and baseflow. The authors evaluate this variability across five primary categories: climate, vegetation, hydrogeology, fire characteristics, and the cryosphere, focusing on both short-term and intermediate recovery periods. A critical finding is that post-wildfire responses often align with hydroclimatic settings where water input and evaporative demand are out of sync, while the pre-wildfire groundwater regime significantly influences the expected outcome and recovery trajectory. This paper provides a collection of testable hypotheses and identifies key areas, particularly the influence of snow dynamics and cryospheric processes, for future monitoring and modeling efforts to improve the prediction of groundwater recovery after fires.

Finally, it outlines five interconnected categories of progress being made toward wildfire resilience in BC including planning, operations, networking, research and knowledge generation, and public engagement, highlighting the need for an all-of-society approach and proactive, dynamic management.

This paper investigates how wildfires influence the upward migration of tree species in California's subalpine forests, a phenomenon often linked to climate change. Researchers examined post-fire tree regeneration across various fire severities, focusing on the contrasting responses of shade-tolerant and shade-intolerant conifer species. While overall montane species regeneration decreased in burned areas, shade-intolerant Jeffrey pine showed increased success in severely burned plots, aligning with predictions of higher climatic suitability. Conversely, shade-tolerant red fir regeneration declined significantly with higher fire severity, suggesting that the specific regeneration niche of a species, its ideal post-fire conditions, is critical in determining whether fire facilitates or hinders its range expansion.
