Managing Future Risk of Increasing Simultaneous Megafires

Our overall research goal is to understand current and future wildfire characteristics to support fire-related decisions throughout the 21st century in the face of resultant suppression resource scarcity and competition in the US. This project will model future patterns and uncertainty in the simultaneous co-occurrence of megafire events to inform risk management.  

 Research Questions:  

1. How will climate change alter future patterns of wildfire, particularly co-occurring megafires?  
2.  What implications does this hold for risk management decisions?    

We are developing statistical models to represent relationships between biogeophysical and human factors (e.g., ignitions, suppression policy, land and fuel management) and firefighting resource demand at geographical scales relevant to firefighting management decision-making. These resource demand and risk management models will be based on wildfire characteristics, climate, weather, and land history covariates. We are evaluating climate change impacts on ignition patterns and on wildfire risk with regional climate model projections from NA-CORDEX, and observations from the gridMET dataset, by looking at fire danger indices in concert with projected spatiotemporal patterns in anthropogenic activities associated with human-caused fires, as well as diagnostics for lightning activity.

Hypotheses: 

1. We hypothesize that ignition efficiency will increase further with warming, facilitating increased lightning-ignitions, and consequently increases in simultaneous wildfire events.  
2. We hypothesize that a positive feedback may occur where fire suppression resources at the national level become strained, reducing the efficacy of managing active fires and new ignitions, and further increasing resource strain and relative burned area.  
3. We hypothesize that short term fire management decisions (e.g., both fuel management and fire suppression) have significant delayed impacts, and demand innovative scientifically supported decision tools that explicitly account for climate change and the continuing interaction of natural and human systems.

Climate Projections and Simultaneous Wildfires

• Fire weather meteorologists can make better near-term predictions of the number of daily ignitions and the occurrence of large wildfires if they take into consideration synoptic-scale weather patterns (Humphrey et al. under revision, 2024).
• Unless we take steps to address the situation – most of the Western US is projected to see numbers of simultaneous, 1000+ acre fires that historically occurred once every ten years happening once every five years – or even more frequently (McGinnis et al., 2022).
• In the US, the median number of large fires (i.e., greater than the historic 75th percentile) occurring simultaneously from July to September was about 3 times higher in 2010-2019 than it was in 1984-1993 (Podschwit and Cullen, 2020; Cullen et al., 2023).
• During the month of peak fire intensity in the US, the number of large fires (i.e., greater than the historic 75th percentile) occurring simultaneously was twice as high in 2010-2019 as it was in 1984-1993 (Podschwit and Cullen, 2020; Cullen et al, 2023).
• In Alaska, the average number of large fires (i.e., greater than the historic 75th percentile) during peak fire activity months approximately doubled in 2002-2019 compared to 1984-2001. In the Northwest US, the average number of large fires during peak fire activity months increased almost 30% between these two periods (Cullen et al, 2023).
• In the Northern Rockies region, conditions of more than 35 simultaneous wildfires 1000+ acres in size, which historically occurred once per decade, are projected to occur on average every two years by the end of this century (McGinnis et al., 2022).

Preparing for Future Wildfire Seasons – Resource Preparedness

• Federal firefighters are earning up to 50% less per month than state firefighters in four western states, despite spending more time on the job. This pay gap poses a substantial barrier to hiring and retaining firefighters for federal roles, which has been reflected in a large percentage of open positions in some locations. (Alkhars et al. 2023)
• As periods of co-occurring wildfire increasingly overlap across US regions, competition for suppression resources has been increasing, a trend which is expected to continue and intensify. (Podschwit and Cullen, 2020; Cullen et al., 2020).
• The current capacity, in terms of hiring, staffing and preparing, of fire operations organizations is insufficient for responding effectively in the coming decades given the projected number and intensity of impactful fires. (Podschwit and Cullen, 2020; Cullen et al., 2020).
• In the Western US, the season during which wildfires compete for suppression resources is projected to begin 2-4 weeks earlier and end 2 weeks later in 2040-2070 than it did during 1980-2010. Overall, wildfire season length will increase by 4-6 weeks. (McGinnis et al, 2022).
• In 2021, the US national preparedness level reached its maximum (PL=5) at the earliest point in the year ever recorded, 14 July, indicating that suppression resources were already fully committed in response to simultaneous active fires at that date. (Abatzoglou et al., 2021).
• With increasing intensity of wildfire seasons, national resources will be subject to ever higher levels of competition, necessitating increased reliance on international resource-sharing relationships. (Bloem et al., 2022).

Proactive Forest Management (Mitigating fire risk under climate change)

• Fire management in the US must become proactive rather than reactive in the face of the lengthening of the simultaneous wildfire season by several weeks, alongside a notable increase in the risk of extreme fire weather.
• In recent decades, increased area burned by western wildfires has been associated with uncharacteristically large patches of high-severity, stand-replacing fire. (Parks and Abatzoglou 2020, Hagmann et al. 2021).
• Because high-severity fire events can be catalysts for vegetation change, trends in large wildfires and burn severity have implications for rapid ecosystem shifts and declines in valued resources. (Kemp et al. 2019, Stevens-Rumann and Morgan 2019, Coop et al. 2020).
• Combining western science and Indigenous knowledge systems is foundational to intentionally restoring and adapting western forest ecosystems (Kimmerer and Lake 2001, Lake et al. 2017, Roos et al. 2021).” (Prichard et al. 2021)
• Adaptive management is a learning-by-doing method of responding to ecosystem changes, informed by effectiveness monitoring. (Lyons et al. 2008, Larson et al. 2013b).
• Restoring open forest structure and composition, favoring larger tree sizes, and reducing surface fuels can effectively mitigate future wildfire severity in dry, fire-prone forests, including oak and pine woodland and semi-arid mixed conifer forests of the western US.
• Despite calls to restore fire as a cultural and ecological process (e.g., The U.S. National Wildland Fire Cohesive Strategy), the dominant approach to wildfire management continues to be aggressive suppression. (Prichard et al. 2021)
• Under active fire suppression, forest infilling and fuel accumulation predisposes forests to high-severity fire when fire inevitably returns to the locations where it has been previously suppressed. (North et al. 2015b)
