Human Dimensions of Fire

We evaluated the prominence and function of feedback loops embedded in cognitive maps—beliefs about patterns of causal relationships that drive system dynamics—elicited from a diverse cross-section of stakeholders in a fire-prone region in the U.S. West. We demonstrate that cognition of feedback loops is rare among individuals, but increasingly prominent within aggregations of cognitive maps, which underscores the importance of collaborative decision-making. Our analysis further reveals a bias toward perception of amplifying feedback loops and of loops in which management actions result in desirable outcomes, which points to areas where progress may be made in reforming wildfire risk governance.

Increasing wildfire size and severity across the western United States has created an environmental and social crisis that must be approached from a transdisciplinary perspective. Climate change and more than a century of fire exclusion and wildfire suppression have led to contemporary wildfires with more severe environmental impacts and human smoke exposure. Wildfires increase smoke exposure for broad swaths of the US population, though outdoor workers and socially disadvantaged groups with limited adaptive capacity can be disproportionally exposed. Exposure to wildfire smoke is associated with a range of health impacts in children and adults, including exacerbation of existing respiratory diseases such as asthma and chronic obstructive pulmonary disease, worse birth outcomes, and cardiovascular events. Seasonally dry forests in Washington, Oregon, and California can benefit from ecological restoration as a way to adapt forests to climate change and reduce smoke impacts on affected communities.

By mobilizing a timely and safe initial response, early detection technologies, strategic networks of fuel breaks, and Rangeland Fire Protection Associations help “minimize the bad days” on the fireline and improve suppression success on a vast and remote landscape.

Research organizations like Rocky Mountain Research Station may be able to institutionalize co-production by adjusting the way they incentivize and evaluate researchers, increasing investment in science delivery and scientific personnel overall, and supplying long-term funding to support time-intensive collaborations. These sorts of structural changes could help transform the culture of fire science so that coproduction is valued alongside more conventional scientific activities and products.

In this paper, researchers seek to address this question based on interviews with leaders engaged in the management of jurisdictionally complex wildfire incidents. They propose a multi-level framework for conceiving co-management as strategic efforts of individual actors to cooperatively manage perceived interdependencies with others through one or more formal or informal institutional arrangements. They then demonstrate the value of the proposed framework in its ability to organize a series of questions for diagnosing co-management situations within the context of jurisdictionally complex wildfires.

Federally owned public lands, originally designated to properly manage natural resources, are prone to wildfire in the southern Rocky Mountains, a risk which has increased as a result of environmental conditions and historical land management. Outdoor recreation has become increasingly prevalent since the twentieth century, providing greater access to fire-prone lands. Using San Juan National Forest as the study site, this presentation explores research analyzing the influence outdoor recreation and human access have on anthropogenic wildfire occurrence and size in the southern Rocky Mountains. GIS methodologies and statistical analysis demonstrate the impact designated outdoor recreation locations have on anthropogenic wildfires, giving insight into specific usage patterns that result in human-caused wildfire ignitions.

Description: In the southwestern US humans and ecosystems share a history of fire. Here, contemporary ecological patterns and processes that are thought to be natural may be highly influenced by past human land use legacies, at millennial time scales. The Jemez Mountains of central New Mexico provide a landscape laboratory rich in archaeological, ethnographic, and ecological data sets, within which to study the reciprocal, long-term interactions of humans and fire. Evidence from tree-rings, fire scars, and charcoal sediments suggests that prior to the 20th century, southwestern pine forests sustained frequent, low-severity surface fires. During a period of dense occupation in the 13th and 14th centuries, land and resource use may have significantly influenced forest structure, fuel properties, ignitions, and landscape fire dynamics. We developed complex spatial models, informed by rich archaeological, ethnographic, and dendroarchaeological data sets, to examine how plausible scenarios of human activities influenced forests and fire regimes ca. 1200-1900 CE. We found that prehistoric populations influenced forest and fire patterns at broad spatial scales, with feedbacks that maintained ecological resilience. Our results highlight the complexity and extent of long-term human-environment interactions and can be used as a comparative framework within which to evaluate the significance of contemporary and predicted anthropogenic impacts on landscapes and ecosystems.
Presenter: Rachel Loehman is a landscape and fire ecologist with the US Geological Survey. Her research focuses on the role of natural and anthropogenic disturbances in shaping ecological patterns and processes. Her current research projects include developing strategies for enhancing ecosystem and forest resilience to changing climate and disturbance regimes (western U.S.) and monitoring and modeling fire impacts to archaeological resources (southwestern U.S.).

Over the past decade, government policies and programs to incentivize “all-lands approaches” to reducing wildfire risk have emerged that call for collective action among diverse public, private, and Tribal landowners who share fire-prone landscapes. This presentation draws on research from Oregon and California to offer insights into what collective action looks like, when it is desirable, and how to promote it to increase the resilience of fire-prone forests.

Here, we use lands administered by the US Forest Service as a study system to assess the causes, ignition locations, structure loss, and social and biophysical factors associated with cross-boundary fire activity over the past three decades. Results show that cross-boundary fires were primarily caused by humans on private lands. Cross-boundary ignitions, area burned, and structure losses were concentrated in California. Public lands managed by the US Forest Service were not the primary source of fires that destroyed the most structures. Cross-boundary fire activity peaked in moderately populated landscapes with dense road and jurisdictional boundary networks. Fire transmission is increasing, and evidence suggests it will continue to do so in the future. Effective cross-boundary fire risk management will require cross-scale risk co-governance. Focusing on minimizing damages to high-value assets may be more effective than excluding fire from multijurisdictional landscapes.
