Climate & Fire & Adaptation
View article.
Here, we focus on the elevational distribution of forest fires in mountainous ecoregions of the western United States and show the largest increase rates in burned area above 2,500 m during 1984 to 2017. Furthermore, we how that high-elevation fires advanced upslope with a median cumulative change of 252 m (−107 to 656 m; 95% CI) in 34 y across studied ecoregions. We also document a strong interannual relationship between high-elevation fires and warm season vapor pressure deficit (VPD). The upslope advance of fires is consistent with observed warming reflected by a median upslope drift of VPD isolines of 295 m (59 to 704 m; 95% CI) during 1984 to 2017. These findings allow us to estimate that recent climate trends reduced the high-elevation flammability barrier and enabled fires in an additional 11% of western forests. Limited influences of fire management practices and longer fire-return intervals in these montane mesic systems suggest these changes are largely a byproduct of climate warming. Further weakening in the high-elevation flammability barrier with continued warming has the potential to transform montane fire regimes with numerous implications for ecosystems and watersheds.

This Symposium:
- Examined agency/utility wildfire safety, mitigation measures and resiliency planning for future fire weather
- Promoted learning about research focused on wildfire effects on water quality (sediment, contaminants) and water supply in our region and how we can improve our practices
- Discussed how forests, shrublands and rivers are recovering or being impacted by invasive plants and biodiversity loss
- Promoted understand how state and local agencies are preparing and responding to increased threat of wildfire

Hagmann et al. (in press) review a century of observations and multi-scale, multi-proxy research evidence that details widespread changes in forested landscapes and wildfire regimes since the influx of European colonists. Over the preceding 10 millennia, large areas of wNA were already settled and proactively managed with intentional burning by Indigenous tribes. Prichard et al. (in press) then review the research on management practices historically applied by Indigenous tribes and currently applied by some managers to intentionally manage forests for resilient conditions. They address ten questions surrounding the application and relevance of these management practices. Here, we highlight the main findings of both papers and offer recommendations for management. We discuss progress paralysis that often occurs with strict adherence to the precautionary principle; offer insights for dealing with the common problem of irreducible uncertainty and suggestions for reframing management and policy direction; and identify key knowledge gaps and research needs.

Fire and Climate 2022 will bring attention to one of the most important forces shaping wildfire and better prepare how we can focus and respond to this formidable challenge in the new decade. This conference will feature insights, case studies, innovations and opinions from around the world to begin to form a collective, global approach to the wildfire challenge. California has been at the forefront of innovation in wildland fire management and holding a conference in California to fully leverage the lessons learned and adaptive behaviors that will continue to emerge after the Camp Fire will benefit the entire international wildland fire community.

Here, we describe a training approach that we developed to help managers effectively plan to execute intentional, climate-informed actions. This training approach was developed through the Climate Change Response Framework (CCRF) and uses active and focused work time and peer-to-peer interaction to overcome observed barriers to using adaptation planning tools. We evaluate the effectiveness of this approach by examining participant evaluations and outlining the progress of natural resources projects that have participated in our trainings. We outline a case study that describes how this training approach can lead to place and context-based climate-informed action. Finally, we describe best practices based on our experience for engaging natural resources professionals and helping them increase their comfort with climate-informed planning.

This four-hour, virtual Summit was an abbreviated, rescheduled version of ‘Building Bridges and Solutions: Partners in Facing Fire-Science Challenges’ that was cancelled in April due to COVID-19. We assembled scientists and fire practitioners/leaders in an interagency effort to identify fire science and management needs and to discuss decision-making tools and approaches that address resource assessments and adaptation strategies for fire dynamics in future climates in the Southwest (Department of Interior [DOI] Regions 8 and 10 [CA, NV, AZ]). This overriding goal threaded together the Summit’s talks, Q&A, and break-out sessions. Speakers from various agencies, institutes, and academia focused on fire management and planning in future non-analog landscapes and climate-fire-ecosystem impact relationships in western forest (e.g., mixed-conifer, subalpine), desert (hot and cold, grassland, pinyon-juniper, sage-steppe), and Mediterranean/chaparral bioregions. Syntheses from talks, Mentimeter-conducted discussions, and break-out groups on management and actionable-science needs will be summarized in a white paper and posted on the Southwest, Great Basin, and California Fire Science Exchange websites. Let’s work together to address fire science and management in an uncertain future!

Wildland research, management, and policy in western democracies have long relied on concepts of equilibrium: succession, sustained yield, stable age or species compositions, fire return intervals, and historical range of variability critically depend on equilibrium assumptions. Not surprisingly, these largely static concepts form the basis for societal expectations, dominant management paradigms, and environmental legislation. Knowledge generation has also assumed high levels of stasis, concentrating on correlational patterns with the expectation that these patterns would be reliably transferrable. Changes in climate, the introduction of large numbers of exotic organisms, and anthropogenic land conversion are leading to unprecedented changes in disturbance regimes and landscape composition. Importantly, these changes are largely non-reversable; once introduced exotic species are seldom eradicated, climates will continue to warm for the foreseeable future, and many types of land conversion cannot be easily undone.

Studies such as those highlighted in this Research Topic showcase that models provide advances in understanding and provide outcomes that can inform management while being critically challenged and improved by collaborations with field practitioners. Ongoing changes in environmental and societal landscapes and their collective impacts on fire regimes reinforces the need to develop tools that provide guidance how fire management can be used to mitigate fire risk. Bringing together modelers, field ecologists, managers, and practitioners to share their respective knowledge will not only facilitate the development of effective adaptation strategies but also create better science. As Thomas Kuhn simply stated it, the answers you get depend upon the questions you ask and managers do have many questions for the scientists.
