Human Dimensions of Fire
Access resources.
After a catastrophic wildfire, quick action must be taken to minimize social, environmental, and economic devastation. Responsive action requires navigating a complex maze of diverse landowners, community organizations, and numerous local and federal requirements.
Given enough time, forests eventually heal from wildfire. But that healing process can take decades, or even centuries. They simply won’t heal quickly without human intervention. Timely rehabilitation efforts reduce environmental impacts of fire, and can have a positive impact on the community’s social and economic situation in the months and years after the fire. Perhaps most importantly, quick and effective rehabilitation efforts improve public health and safety.

This study involved a statewide survey of participants in Oregon forest collaboratives to examine differences in motivations, perceptions of success, and satisfaction among Forest Service participants (“agency participants”), who made up 31% of the sample, and other respondents (“non-agency”) who represent nonfederal agencies, interest groups, citizens, and non-governmental groups. This study found that agency participants differed from non-agency participants. They typically had higher annual incomes, and were primarily motivated to participate to build trust. However, a majority of all respondents were similar in not indicating any other social or economic motivations as their primary reason for collaborating. A majority also reported satisfaction with their collaborative— despite not ranking collaborative performance on a number of specific potential outcomes highly. Together, this suggests that collaboration in Oregon is currently perceived as successful despite not achieving many specific outcomes.

This study compared fire size, seasonality, and environmental conditions (e.g., wind speed, fuel moisture, biomass, vegetation type) of large human- and lighting-started fires that required a suppression response. Mean large fire size varied by three orders of magnitude: from 1 to 10 ha in the Northeast vs. >1000 ha in the West. Humans ignited four times as many large fires as lightning, and were the dominant source of large fires in the eastern and western U.S. (starting 92% and 65% of fires, respectively). Humans started 80,896 large fires in seasons when lightning-ignited fires were rare. Large human-started fires occurred in locations and months of significantly higher fuel moisture and wind speed than large lightning-started fires.

Let us unpack an “uncomfortable” question: Why don’t women in fire universally encourage more women to join fire? This discussion will be based on the following premise: “fitting in with the firefighter culture is essential for safety and a positive work environment.” I will explore the firefighter culture, how women do this “fitting in,” and implications of the associated lost opportunities for truly diversifying the firefighting workforce. Personal anecdotes, experiences, and woman-related oral tradition will be used to illustrate challenges and highlight possible opportunities for future improvement.

Projections of worsening wildfire conditions under climate change are a major concern in policy and management, but there is little understanding of geographical variation in fire-climate relationships. This analysis relating climate variables to historical fire activity across the United States showed substantial variability in the importance of different seasonal temperature and precipitation variables and of climate overall in explaining fire activity. Climate was significantly less important where humans were more prevalent, suggesting that human influence could override or even exceed the effect of climate change on fire activity. Although climate change may play a significant role in altering future fire regimes, geographical context and human influence should also be accounted for in management and policy decisions.

Fire Adapted Communities Network published 100 blogs in 2017, each one offering a combination of insight, resources, stories and sometimes even humor. Our authors flooded your inboxes with so much wisdom that your biggest challenge may very well have been making time to read it all. In case you’ve missed a blog, or a few (dozen), here are 17 community wildfire resilience takeaways from the last year.

This was a study of ranchers in southeastern Arizona and southwestern New Mexico using Q Methodology to understand their views and motivations about ranching, conservation, and the government. Our results show three complex viewpoints, which we term radical center ranchers (20% of variance), innovative conservationists (19% of variance), and traditional ranchers (12% of variance). A commitment to conservation and corresponding lack of anti-conservation sentiment is held across these viewpoints. Mistrust of government coexists with conservation values for two groups. This information is useful for finding common ground between ranchers and government officials, conservationists, and extension agents on range management and conservation goals.

Human land uses are the primary cause of the introduction and spread of exotic annual Bromus species. Initial introductions were likely linked to contaminated seeds used by homesteading farmers in the late 1880s and early 1900s. Transportation routes aided their spread. Unrestricted livestock grazing from the 1800s through the mid-1900s reduced native plant competitors leaving large areas vulnerable to Bromus dominance. Ecosystems with cooler and moister soils tend to have greater potential to recover from disturbances (resilience) and to be more resistant to Bromus invasion and dominance. Warmer and drier ecosystems are less resistant to Bromus and are threatened by altered fire regimes which can lead to Bromus dominance, impacts to wildlife, and alternative stable states.

In the United States, multi-jurisdictional fire suppression demand is met by a national-scale pool of suppression resources that come from a variety of jurisdictions and provide a wide range of skills, experience, and associated mobility limitations and logistical needs. We designed and implemented an online survey of U.S. Forest Service employees who hold direct or indirect responsibility for ordering suppression resources; our main research objective was to identify the field’s perceptions of resource importance, scarcity, and substitutability. Importantly, we asked questions to help distinguish between resources that are high value, scarce, and without substitutes versus ones that are low value, readily available, and highly substitutable. We hypothesized that resource ordering patterns change with elevated resource scarcity and that, because of this, true resource demand and frequent resource associations and substitutions are not reflected in dispatch summary reports. In this webinar, we will present an overview of our survey results, including future research and analysis plans. Additionally, we will relate the discussion back to firefighter risk, exposure, and risk transfer themes.

This study found evidence of a gap between risk perceptions of WUI residents and wildfire professionals. On average, residents underestimated the overall risk of their property. One third of the study participants reported having a neighbor that they think is increasing their risk. Perceived likelihood of fire reaching the property and causing damages was positively correlated with perceiving a neighbor is not taking action. The only consistent predictor of defensible space was the level of defensible space on neighboring properties. Our results suggest that programs that are effective in getting single homeowners to mitigate risk may have benefits that spillover to neighboring properties, and risk neutral/tolerant individuals lived on parcels that were rated by the professional as having less defensible space and more ignitable structure materials.
