A public engagement protocol: Social science support of planning efforts

USFS webinar recording.

Description: Forest planning and management efforts, including both forest plan revision and comprehensive river management planning, require extensive public engagement. Social science approaches that are practically applied by practitioners within the public engagement process are limited. Armatas and colleagues have developed a “social vulnerability” protocol focused on peoples’ human-nature relationships that can support both decision-making and public relations.

Presenter: Chris Armatas, RMRS research social scientist

4th Annual National Cohesive Wildland Fire Management Strategy Workshop

Visit the workshop website for more information.

The 4th Annual National Cohesive Wildland Fire Management Strategy Workshop theme was: Hard truths, fantastic failures and magnificent successes of cross-boundary, landscape level and community-wide implementation and focused on the following themes:

  • Significant wildland fire events that are changing the way future fires are addressed,
  • “Fantastic Failures” where alignment of ideas and resources did not produce the desired outcomes,
  • “Magnificent Successes” where collaborative, cross-boundary collaboration, prioritization and investments have led to better wildland fire and landscape scale outcomes.

Perceptions of land use planning to reduce wildfire risk in eight communities across the US

View article.

Wildfires are increasingly common in the United States, the result of climate change, altered wildfire regimes, and expanding residential development in close proximity to wildland vegetation. Both suppression expenditures and damages are increasing as a result. Accelerating wildfire losses have been observed in other countries as well: Australia, Canada, Chile, Greece, and Portugal have all experienced record destruction due to wildfires in the past decade. Reducing wildfire losses is a daunting goal requiring a multi-part strategy across all levels of government. In the U.S., federal fire policy seeks to: create resilient landscapes and vegetation; use effective and efficient suppression; and promote fire-adapted communities where human populations and infrastructure can withstand wildfire, reducing loss of life and property.

Exposure complexity and community capacity to manage wildfire risk: Analysis of 60 western US communities

Access article.

We analyzed the relationship between predicted housing exposure to wildfire and local self-assessment of community competence to mitigate wildfire risks in 60 communities in the western US. Results generally demonstrate that (1) the number of sources of wildfire risk influences local housing exposure to wildfire, and (2) perceived community-competence is associated with predicted exposure to wildfire. We suggest that investments in ongoing updates to community risk planning and efforts to build multi-jurisdictional risk management networks may help to leverage existing capacity, especially in moderate capacity communities. The analysis improves the social-ecological understanding of wildfire risks and highlights potential causal linkages between community capacity and wildfire exposure.

Colorado Wildland Fire Virtual Conference

Visit conference website.

This year’s conference, Discover Your Role: Reducing Wildland Fire Risk will provide an in-depth exploration of how community members across the spectrum can effectively contribute to better fire outcomes and provide community wildfire resilience leaders with new knowledge and tools for engaging partners and the public.

Understanding homeowners’ decisions to mitigate wildfire risk and create defensible space

View article.

This article analyses homeowners’ decisions to undertake fire-safe investments and create defensible space on their property using a unique dataset from 35 wildland–urban interface communities in Nevada. The dataset combines homeowner information from a mail survey with their observed fire-safe investments obtained through parcel-level hazard assessments. We find that homeowners’ self-reported mitigation expenditures are driven by their subjective beliefs about their wildfire risk, whereas observed defensible space status is driven by their costs of investment. We develop a theoretical model of a homeowner’s fire-safe investment decision that accounts for our empirical results.

Factors associated with structure loss in 2018 CA wildfires

View study.

This study compiled and analyzed an extensive dataset of building inspectors’ reports documenting homeowner mitigation practices for more than 40,000 wildfire-exposed structures from 2013–2018. Comparing homes that survived fires to homes that were destroyed, we investigated the role of defensible space distance, defensive actions, and building structural characteristics, statewide and parsed into three broad regions. Overall, structural characteristics explained more of a difference between survived and destroyed structures than defensible space distance. The most consistently important structural characteristics—having enclosed eaves, vent screens, and multi-pane windows—were those that potentially prevented wind-born ember penetration into structures, although multi-pane windows are also known to protect against radiant heat. In the North-Interior part of the state, active firefighting was the most important reason for structure survival. Overall, the deviance explained for any given variable was relatively low, suggesting that other factors need to be accounted for to understand the full spectrum of structure loss contributors. Furthermore, while destroyed homes were preferentially included in the study, many “fire-safe” structures, having > 30 m defensible space or fire-resistant building materials, were destroyed. Thus, while mitigation may play an important role in structure survival, additional strategies should be considered to reduce future structure loss.

Severe Fire Danger Index: Informing firefighter and community risk

View article.

This study presents the development and evaluation of a spatial fire danger index that can be used to assess historical events, forecast extreme fire danger, and communicate those conditions to both firefighters and the public. It uses two United States National Fire Danger Rating System indices that are related to fire intensity and spread potential. These indices are normalized, combined, and categorized based on a 39-yr climatology (1979–2017) to produce a single, categorical metric called the Severe Fire Danger Index (SFDI) that has five classes; Low, Moderate, High, Very High, and Severe. We evaluate the SFDI against the number of newly reported wildfires and total area burned from agency fire reports (1992–2017) as well as daily remotely sensed numbers of active fire pixels and total daily fire radiative power for large fires (2003–2016) from the Moderate-Resolution Imaging Spectroradiometer (MODIS) across the conterminous United States. We show that the SFDI adequately captures geographic and seasonal variations of fire activity and intensity, where 58% of the eventual area burned reported by agency fire records, 75.2% of all MODIS active large fire pixels, and 81.2% of all fire radiative power occurred when the SFDI was either Very High or Severe (above the 90th percentile).

Acknowledging the presence of decision biases amongst emergency managers

Access brief.

This study specifically surveyed county emergency managers; the individuals who are responsible for mitigating and responding to disaster events. The results suggest that emergency managers are subject to decision biases and by knowing this, we can improve emergency management and decision-making processes.
