Risk Assessment and Analysis

In this study we illustrate the value of social data compiled at the community scale to guide a local wildfire mitigation and education effort. The four contiguous fire-prone study communities in North Central Washington, US, fall within the same jurisdictional fire service boundary and within one US census block group.

Fire risk management is at a crossroads. The last three fire seasons worldwide, dotted by extreme fire behavior and “megafire” events, highlighted the need for a shifting mentality towards a novel and integrated fire management framework, flexible, adaptive, and responsive to the changing environmental and societal conditions.

Indigenous fire stewardship enhances ecosystem diversity, assists with the management of complex resources, and reduces wildfire risk by lessening fuel loads. Although Indigenous Peoples have maintained fire stewardship practices for millennia and continue to be keepers of fire knowledge, significant barriers exist for re-engaging in cultural burning.

Background. In wildland–urban interface (WUI) fires, particulates from the combustion of both natural vegetative fuels and engineered cellulosic fuels may have deleterious effects on the environ- ment. Aims. The research was conducted to investigate the morphology of the particulate samples generated from the combustion of oriented strand board (OSB).

Purpose The way that disasters are managed, or indeed mis-managed, is often represented diagrammatically as a “disaster cycle”.

This report focuses on a critical aspect of working towardscommunity fire adaptation: analyzing effective land use policy and regulatory solutions in thewildland-urban interface (WUI). The WUI is any area where the built and natural environmentscreate a set of conditions that allow for the ignition and continued spread of wildfire.

Wildfire is an annual threat for many rural communities in the Pacific Northwest region of the United States. In some severe events, evacuation is one potential course of action to gain safety from an advancing wildfire.

Supporting wildfire management activities is frequently identified as a benefit of forestroads. As such, there is a growing body of research into forest road planning, construction, andmaintenance to improve fire surveillance, prevention, access, and control operations.

Optimized wildfire risk reduction strategies are generally not resilient in the event of unanticipated, or very rare events, presenting a hazard in risk assessments which otherwise rely on actuarial, mean-based statistics to characterize risk.

Large-scale, high-severity wildfires are a major challenge to the future social-ecological sustainability of fire-adapted forest ecosystems in the American West. Managing forests to mitigate this risk is a collective action problem requiring landowners and stakeholders within multi-ownership landscapes to plan and implement coordinated restoration treatments.
