Characterizing large airtanker use in United States fire management

Publications Posted on: September 30, 2015
The appropriate role of large airtankers (LATs) in federal fire suppression in the United States has been the source of much debate and discussion in recent years as the U.S. Forest Service (USFS) has faced impending decisions about how best to address an aging fleet of contracted aircraft. Questions of fleet efficiency are complicated by inadequacies in historical data on airtanker use.

Regional likelihood of very large wildfires over the 21st century across the western United States: Motivation to study individual events like the Rim Fire, a unique opportunity with unprecedented remote sensing data

Publications Posted on: September 30, 2015
Studies project that a warming climate will likely increase wildfire activity in many areas (Westerling and others 2002; Flannigan and others 2005, 2009; Littell and others 2009). These analyses are often of aggregate statistics like annual area burned, which are insufficient for analyzing changes in seasonality of fire events, the temporal resolution useful for fire management and understanding what drives individual events.

Near real-time wildfire mapping using spatially-refined satellite data: The rim fire case study

Publications Posted on: September 30, 2015
Fire incident teams depend on accurate fire diagnostics and predictive data to guide daily positioning and tactics of fire crews. Currently, the U.S. Department of Agriculture - Forest Service National Infrared Operations (NIROPs) nighttime airborne data provides daily information about the fire front and total fire affected area of priority fires to the incident teams on the ground.

Initial results from a field experiment to support the assessment of fuel treatment effectiveness in reducing wildfire intensity and spread rate

Publications Posted on: September 30, 2015
Hazardous fuel reduction treatments conducted both through prescribed fire and mechanical means are a critical part of the mitigation of wildland fire risk in the United States. The US Federal Government has spent an average of $500t million each year on fuel reduction, from 2002-2012 (Gorte 2011).

Temporal changes to fire risk in dissimilar WUI communities

Publications Posted on: September 30, 2015
Despite increasing proportions of governmental budgets allocated to fire suppression resources, wildfires annually destroy great numbers of homes and critical infrastructure in the wildland-urban interface (WUI).

Manitoba Health's emerging work on wildland fire smoke

Publications Posted on: September 30, 2015
Smoke caused by wildland fire events is an important public health issue, involving major risks to the health of people and the environment. Smoke from wildland fires can travel hundreds of kilometers, affecting air quality far from the flames.

A tale of two fires: The relative effectiveness of past wildfires in mitigating wildfire behavior and effects

Publications Posted on: September 30, 2015
The incidence of large, costly landscape-scale fires in western North America is increasing. To combat these fires, researchers and managers have expressed increased interest in investigating the effectiveness of past, stand-replacing wildfires as bottom-up controls on fire spread and severity. Specifically, how effective are past wildfires in mitigating the behavior and effect of future fires, and for how long?

Characterization of the large fire regime in SE France

Publications Posted on: September 29, 2015
Southeastern France is the most wildfire prone region of the country, covering 14.7 percent of its land area-entire country, is the region most affected by wildfires, with 55 percent of the total number of fires recorded in the whole country from 2006 to 2008. It is a typical Mediterranean climate with hot and dry summers, often with strong NW wind, and includes plant communities well adapted to these drastic climate conditions.

Influences of previous wildfires on change, resistance, and resilience to reburning in a montane southwestern landscape

Publications Posted on: September 29, 2015
Land use legacies and climate have altered fire regimes across montane forests of much of the southwestern US (Allen and others 2002), and several recent wildfires have been extremely large and severe (Dennison and others 2014).

Enhancing scientist-manager relationships to foster ecosystem resilience

Publications Posted on: September 29, 2015
This extended abstract describes the preliminary results of a study that sought to determine the most effective ways to develop and apply scientific information about resilience for on-the-ground management. Interviews were conducted with scientists, managers, and other stakeholders in the Southwest U.S. following a workshop on ecosystem resilience held in Tucson, Arizona in February 2014.
