Fire History
Year of Publication
2023
Publication Type
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.
Evidence for multi-decadal fuel buildup in a large California wildfire from smoke radiocarbon measurements
Year of Publication
2023
Publication Type
In recent decades, there has been a significant increase in annual area burned in California's Sierra Nevada mountains. This rise in fire activity has prompted the need to understand how historical forest management practices affect fuel composition and emissions.
Contemporary wildfires are more severe compared to the historical reference period in western US dry conifer forests
Year of Publication
2023
Publication Type
Dry conifer forests in the western US historically experienced frequent fire prior to European American colonization. Mean fire return interval ranged from about 5–35 years, with the majority of fires burning at low-to-moderate severity.
Does large area burned mean a bad fire year? Comparing contemporary wildfire years to historical fire regimes informs the restoration task in fire-dependent forests
Year of Publication
2023
Publication Type
Wildfires and fire seasons are commonly rated largely on the simple metric of area burned (more hectares: bad). A seemingly paradoxical narrative frames large fire seasons as a symptom of a forest health problem (too much fire), while simultaneously stating that fire-dependent forests lack sufficient fire to maintain system resilience (too little fire).
Vegetation type change in California’s Northern Bay Area: A comparison of contemporary and historical aerial imagery
Year of Publication
2023
Publication Type
The North Bay area of California is a populous and ecologically diverse area that has experienced significant changes in the past century, as well as a series of recent wildfires, after over a century of fire suppression practices.
Consistent, high-accuracy mapping of daily and sub-daily wildfire growth with satellite observations
Year of Publication
2023
Publication Type
Background: Fire research and management applications, such as fire behaviour analysis and emissions modelling, require consistent, highly resolved spatiotemporal information on wildfire growth progression.
Changes in wildfire occurrence and risk to homes from 1990 through 2019 in the Southern Rocky Mountains, USA
Year of Publication
2023
Publication Type
Wildfires and housing development have increased since the 1990s, presenting unique challenges for wildfire management. However, it is unclear how the relative influences of housing growth and changing wildfire occurrence have altered risk to homes, or the potential for wildfire to threaten homes.
Cross-boundary cooperation in wildfire management during the custodial management period of the US Forest Service: A case study of the eastern Cascades of Oregon, USA, 1905–1945
Year of Publication
2023
Publication Type
In the U.S., federal, tribal, state, local, and private land management entities seek to implement a wildfire management strategy that spans large spatial extents and multiple ownerships to achieve wildfire risk reduction and forest restoration. This strategy requires cross-boundary cooperation.
Postglacial vegetation and fire history with a high-resolution analysis of tephra impacts, High Cascade Range, Oregon, USA
Year of Publication
2023
Publication Type
The postglacial history of vegetation, wildfire, and climate in the Cascade Range (Oregon) is only partly understood. This study uses high-resolution macroscopic charcoal and pollen analysis from a 13-m, 14,500 years sediment record from Gold Lake, located in a montane forest, to reconstruct forest vegetation and fire history.
Lizards' response to the sound of fire is modified by fire history
Year of Publication
2023
Publication Type
Highlights • Lizards surviving wildfires are more alert to fire sound than those in unburned areas. • Lizards living in urban areas reacted to fire sound similarly to wildfire survivors. • Both natural and human-driven disturbances can shape the behaviour of animals. • Fires are likely to be an important selective pressure on animal behaviour.
