[from the text] Our steering committee is dedicated to advancing federal policy to support wider use of prescribed fire and wildfire managed for resource benefits. Both these uses of fire are essential tools for fuel reduction, community protection…

As the wildland–urban interface continues to expand into fire prone areas, future wildfires will likely result in the burning of more built structures, such as the recent Marshall Fire in Colorado, which increases the complexity of the wildfire…

Year Published:

Wildland fire behavior models are often initiated using the detection information listed in incident reports. This information carries an unknown amount of uncertainty, though it is often the most readily available ignition data. To determine the…

The suggestion has been made within the wildland fire community that the rate of spread in the upper portion of the fire danger spectrum is largely independent of the physical fuel characteristics in certain forest ecosystem types. Our review and…

Prescribed fire is an increasingly important tool in restoring ecological conditions and reducing uncontrolled wildfire. Prescribed burn techniques could reduce public health impacts associated with wildfire smoke exposure. However, there have been…

Year Published:

Belowground bud bank regeneration is a successful strategy for plants in fire-prone communities. It depends on the number and location of dormant and viable buds stored on belowground organs. A highly diverse belowground bud-bearing organ system…

Year Published:

Fires are widespread disturbance events with many implications for different aspects of plant persistence and vegetation properties. Changing fire regimes can profoundly affect vegetation dynamics and ecosystem properties. Recent steep increases in…

Year Published:

Mechanical mastication is a fuel management strategy that modifies vegetation structure to reduce the impact of wildfire. Although past research has quantified immediate changes to fuel post-mastication, few studies consider longer-term fuel…

Year Published:

In fire-dependent forest landscapes, frequent low- to moderate-severity fire maintained vegetation patterns that limited the severity of droughts, wildfires, and insect and pathogen activity. More than a century of fire exclusion, in combination…

Composition of pyrolysis gases for wildland fuels is often determined using ground samples heated in non-oxidising environments. Results are applied to wildland fires where fuels change spatially and temporally, resulting in variable fire behaviour…
