Researchers have unveiled a new framework for understanding wildfire risk in the southeastern United States, classifying the region into nine distinct “firescapes.” Each of these firescapes represents different landscape types that share similar ecological, sociopolitical, and fire threat attributes. They provide important guidance for policy makers and fire management practitioners. This comprehensive study aims to enhance strategic fire management in the South, addressing the complex dynamics of wildfire risks that vary even within localized areas.
Nicholas Gould directed the research, with very strong support from the USDA Forest Service. Using over 70 datasets, they assessed a wide range of factors that affect wildfire risk, including the impacts of fire and smoke, community vulnerability, forest conditions, climate, and land use. This study takes a look at the impacts of wildfire hazards to our critical infrastructure and communities. Further, it exposes the disproportionate amounts of danger that people experience throughout the South.
Understanding Firescapes
These newly defined firescapes present a more complex and textured picture of wildfire risk. Each firescape includes areas with similar ecological characteristics and community risks. Likewise, the mountain forests of the Ozarks and southern Appalachians do best under wetter, cooler, mountain climates. Under those conditions, the likelihood of extreme-intensity wildfires is usually reduced.
Researchers are especially clear to highlight that not all people living in the same geographical space are at equal risk from wildfires. “The social vulnerability aspect is driven by wanting to understand what makes people more or less vulnerable to wildfire,” said Lars Pomara of the USDA Forest Service. “We didn’t want to look at risk in a general way, but really define who is most at risk.”
This distinction is important for efficient resource allocation and strategic decision-making in the fight against wildfires. Policymakers at the local, regional, and state levels can use the lessons learned from this analysis to customize interventions that mitigate the most acute vulnerabilities in their communities.
Collaborative Efforts and Data-Driven Insights
The project represents a significant collaborative effort among various stakeholders dedicated to fire management and research. Pomara described it as the most collaborative project he’d ever worked on. He couldn’t stress enough the need for communication – not just to other academics.
“This is one of the most collaborative projects I’ve been involved with. To the extent that this is a well-communicated project, available outside of the research bubble, I think that can be credited to our partners.” – Lars Pomara
We know this study requires heavy data collection. It creates an important bedrock for understanding wildfire risk all across the wildland-urban interface and beyond. Incorporating social vulnerability metrics into wildfire risk assessments is an important step forward in informing more holistic fire management strategies. This multi-pronged strategy allows decision-makers at all levels to determine areas at the highest risk most efficiently and carry out tailored risk mitigation efforts.
Implications for Fire Management
The ramifications of this study reach many actors in the wildland fire and land management arena. As the Southeast experiences a growing wildfire threat, new tools are needed to be on the cutting edge of strategic fire management. Our research uncovered that places with the highest potential for risk reduction tend to overlap with the most high-risk areas. Nowhere is this more true than in places like Florida and southeast Texas.
By utilizing these updated tools, policymakers and fire managers can better navigate the complexities of wildfire risks while promoting community resilience. The research offers a roadmap for understanding how ecological factors intersect with social vulnerabilities, ultimately leading to more informed decisions regarding resource allocation and disaster preparedness.
