Increasing area burned across western North America raises questions about the precedence and magnitude of changes in fire activity, relative to the historical range of variability (HRV) that ecosystems experienced over recent centuries and millennia.
Assessing the effectiveness and measuring the performance of fuel treatments and other wildfire risk mitigation efforts are challenging endeavors. Perhaps the most complicated is quantifying avoided impacts. In this study, we show how probabilistic counterfactual analysis can help with performance evaluation.
Yellow pine and mixed-conifer (YPMC) forests of California’s Sierra Nevada have experienced widespread fire suppression for over a century, resulting in ingrowth and densification of trees, heavy fuel accumulation, and shifts in species composition.
The increasing frequency of severe wildfires demands a shift in landscape management to mitigate their consequences. The role of managed, low-intensity fire as a driver of beneficial fuel treatment in fire-adapted ecosystems has drawn interest in both scientific and policy venues.
As wildfires are increasingly causing negative impacts to communities and their livelihoods, many communities are demanding more proactive and locally driven approaches to address wildfire risk. This marks a shift away from centralized governance models where decision-making is concentrated in government agencies that prioritize reactive wildfire suppression.
While increased length and intensity of wildfire seasons in many places have led to more concern about wildland firefighter safety, we believe ethnography has been underutilized as a method within this domain. In response, we begin building a shared idiom for ethnographic engagement with wildland firefighter safety and similar occupations.
Media provide crucial information about wildfires and can be key messengers about fire’s role in our landscapes and communities. This summer, the Oregon State University Extension Fire Program and University of Oregon School of Journalism and Communication collaboratively published a new resource guide to support effective media coverage of wildfires and related topics. Although developed for Oregon, the guide’s insights and suggestions are applicable across the Northwest. Join the authors to learn more about how media in all forms can report diverse stories of fire, including strategies for physical and mental preparedness, engaging with incident personnel, and using scientific knowledge.
To enhance Oregon’s wildfire resilience, the State Legislature passed the 2021 SB 762 Omnibus Wildfire Bill that enacted recommendations from the Governor’s 2019 Wildfire Council. This included a $220M investment in landscape resilience, suppression response, as well as some new regulations for the home ignition zone for community protection. Upon release of a map showing statewide hazard, there was a significant public outcry, often based on misunderstandings or misinformation, that ultimately led to the map being rescinded and reworked. Join us for this webinar, where we will explore the broader intent of the legislation, its requirements for mapping, where the effort stands today, and what we continue to learn from the public’s reaction.
Objectives. To describe demographic and social characteristics of US communities exposed to wildfire smoke.
Snags, standing dead trees, are becoming more abundant in forests as tree mortality rates continue to increase due to fire, drought, and bark beetles. Snags provide habitat for birds and small mammals, and when they fall to the ground, the resulting logs provide additional wildlife habitat and affect nutrient cycling, fuel loads, and fire behavior.
