Wildfire Risk to California Communities

We assessed wildfire risk to homes and communities in California as part of a larger assessment of wildfire hazard across the state. In July 2019 the Pacific Southwest Region of the U.S. Forest Service contracted with Pyrologix to conduct a spatial wildfire hazard assessment across all land ownerships. This summary of wildfire risk to California […]

A fuelscape for all land ownerships in the state of California

The Pacific Southwest Region of the USDA Forest Service contracted Pyrologix to complete an assessment of wildfire hazard across all land ownerships in the state of California. The foundation of any wildfire hazard assessment is a current-condition fuelscape, updated for recent disturbances and calibrated to reflect the fire behavior potential realized in recent historical wildfire […]

USFS Region 4 Wildfire Hazard Report: methods and results

The purpose of the USFS Region 4 Quantitative Wildfire Hazard Report is to provide foundational information about wildfire hazard across the geographic area. Such information supports wildfires, regional fuel management planning decisions, and revisions to land and resource management plans. The R4 analysis considers: likelihood of a fire burning, the intensity of a fire if […]

FSim: the large-fire simulator — Guide to Best Practices version 0.3.1

FSim—the large-fire simulation system—is a comprehensive wildfire occurrence, growth and suppression simulation system that estimates wildfire probability and intensity across a large landscape (Finney and others 2011). Because large fires are rare, FSim generates many thousands of years of simulations, in order to capture a long enough time period to generate burn probabilities for the […]

Region 2–San Juan National Forest Quantitative Wildfire Risk Assessment: Methods and Results

The purpose of the Region 2: San Juan National Forest Risk Assessment (R2SJ) is to provide foundational information about wildfire hazard and risk to highly valued resources and assets across the geographic area. Such information supports wildfires, fuel management planning decisions, and revisions to land and resource management plans. A wildfire risk assessment is a […]

Region 2–Rio Grande National Forest Quantitative Wildfire Risk Assessment: Methods and Results

The purpose of the Region 2: Rio Grande National Forest Risk Assessment (R2RG) is to provide foundational information about wildfire hazard and risk to highly valued resources and assets across the geographic area. Such information supports wildfires, fuel management planning decisions, and revisions to land and resource management plans. A wildfire risk assessment is a […]

USFS Region 5–Southern California Quantitative Wildfire Risk Assessment: Methods and Results

The purpose of the USFS Region 5 Southern California Wildfire Risk Assessment (SCRA) is to provide foundational information about wildfire hazard and risk to highly valued resources and assets across the geographic area. Such information supports wildfires, regional fuel management planning decisions, and revisions to land and resource management plans. A wildfire risk assessment is […]

Exposure of human communities to wildfire in the Pacific Northwest

At the request of the United States Forest Service Pacific Northwest Regional Office, Pyrologix1 assessed the exposure to wildfire of housing units within named human communities across the Pacific Northwest Region (Oregon and Washington). The purpose of the assessment was to identify the communities most threatened by wildfire. The fifty most-threatened communities in each state […]

Teton Interagency Wildfire Hazard Report: Methods and Results

The purpose of the Teton Interagency Wildfire Hazard Report is to provide foundational information about wildfire hazard across the geographic area. Such information supports wildfires, regional fuel management planning decisions, and revisions to land and resource management plans. The TIARA analysis considers: likelihood of a fire burning, the intensity of a fire if one should […]
