Wildland fuels are a critical factor in fire management because they are the one factor that managers can control. However, fuels have always been defined, described, and quantified in the context of inputs to fire behavior models. Wildland fuel…

Very large fires (VLFs) have important implications for communities, ecosystems, air quality and fire suppression expenditures. VLFs over the contiguous US have been strongly linked with meteorological and climatological variability. Building on…
Year Published:
It is hypothesized that climate impacts forest mosaics through dynamic ecological processes such as wildfires. However, climate-fire research has primarily focused on understanding drivers of fire frequency and area burned, largely due to scale…
Year Published:
Wildfire can affect soil hydraulic properties, often resulting in reduced infiltration. The magnitude of change in infiltration varies depending on the burn severity. Quantitative approaches to link burn severity with changes in infiltration are…
Year Published:
Although there is acute concern that insect-caused tree mortality increases the likelihood or severity of subsequent wildfire, previous studies have been mixed, with findings typically based on stand-scale simulations or individual events. This…

From a fire policy of prevention at all costs to today's restored burning, Between Two Fires is America's history channeled through the story of wildland fire management. Stephen J. Pyne tells of a fire revolution that began in the 1960s as a…
Year Published:
Forests that historically burned in mixed-severity fire regimes prove difficult to manage, especially when they border homes and prized recreation areas. This management challenge was the focus of the Fuels Reduction and Restoration in Mixed-Conifer…
Year Published:
Wildfire activity is predicted to increase with global climate change, resulting in longer fire seasons and larger areas burned. The emissions from fires are highly variable owing to differences in fuel, burning conditions and other external…

The Forest Service has declared its intention of becoming a learning organization. As a means to that end, the Forest Service has borrowed and adapted the staff ride concept from the military. This paper describes the staff ride product and compares…
Year Published:
Fuel treatments have been widely used as an effective fire management tool to mitigate catastrophic wildland fire risk in forested landscapes. Fire research efforts of the last two decades have significantly advanced fire behavior modeling and fuel…
Year Published:
Forest restoration efforts require thinning operations to reduce tree density, wildfire risk, or insect and disease conditions to improve ecosystem processes and function. However, one issue with the thinned stands is to dispose of the residues.…
Year Published:
Time-varying fire-climate relationships may represent an important component of fire-regime variability, relevant for understanding the controls of fire and projecting fire activity under global-change scenarios. We used time-varying statistical…
Year Published:
Federal fire management plans are essential implementation guides for the management of wildland fire on federal lands. Recent changes in federal fire policy implementation guidance and fire science information suggest the need for substantial…

It is hypothesized that climate impacts forest mosaics through dynamic ecological processes such as wildfires. However, climate-fire research has primarily focused on understanding drivers of fire frequency and area burned, largely due to scale…
Year Published:
The U.S. Department of Agriculture (USDA), Forest Service is recognized as a leader among Federal land management agencies in partnering collaboratively with American Indian and Alaska Native governments and indigenous communities. The Forest…

With just over 3 months remaining, it looks like 2015 could be a record-breaking year for wildfires in the United States. So far this year, more than 8.5 million acres have burned and severe fires often happen in October. For the first time, the U.S…

There is no uniform means for assessing social impact from wildland fires beyond statistics such as home loss, suppression costs and the number of residents evacuated. In this paper we argue for and provide a more comprehensive set of considerations…
Year Published:
More than a century of forest and fire management of Inland Pacific landscapes has transformed their successional and disturbance dynamics. Regional connectivity of many terrestrial and aquatic habitats is fragmented, flows of some ecological and…
Year Published:
Climate change is expected to drive increased tree mortality through drought, heat stress, and insect attacks, with manifold impacts on forest ecosystems. Yet, climate-induced tree mortality and biotic disturbance agents are largely absent from…
Year Published:
Humans cause more than 55% of wildfires on lands managed by the USDA Forest Service and US Department of the Interior, contributing to both suppression expenditures and damages. One means to reduce the expenditures and damages associated with these…
