A global index for mapping the exposure of water resources to wildfire

Publications Posted on: November 18, 2016
Wildfires are keystone components of natural disturbance regimes that maintain ecosystem structure and functions, such as the hydrological cycle, in many parts of the world. Consequently, critical surface freshwater resources can be exposed to post-fire effects disrupting their quantity, quality and regularity. Although well studied at the local scale, the potential extent of these effects has not been examined at the global scale.

Assessing spatially heterogeneous forest structure impact on fire behavior in ponderosa pine and dry mixed conifer forests

Projects Posted on: August 17, 2016
Restoration projects are being implemented across large scales in fire-frequent forests to simultaneously modify forest structure complexity and reduce potential crown fire hazards. However, there has been little assessment of the ability for these projects to simultaneously meet the objectives of increasing spatial diversity and reducing wildfire hazards.

Integrating pixel- and polygon-based approaches to wildfire risk assessment: Application to a high-value watershed on the Pike and San Isabel National Forests, Colorado, USA

Publications Posted on: July 28, 2015
We develop a novel risk assessment approach that integrates complementary, yet distinct, spatial modeling approaches currently used in wildfire risk assessment.

Restoration of fire in managed forests: a model to prioritize landscapes and analyze tradeoffs

Publications Posted on: January 26, 2015
Ongoing forest restoration on public lands in the western US is a concerted effort to counter the growing incidence of uncharacteristic wildfire in fire-adapted ecosystems. Restoration projects cover 725,000 ha annually, and include thinning and underburning to remove ladder and surface fuel, and seeding of fire-adapted native grasses and shrubs.

Quantifying the threat of unsuppressed wildfires reaching the adjacent wildland-urban interface on the Bridger-Teton National Forest, Wyoming

Publications Posted on: September 20, 2012
An important objective for many federal land management agencies is to restore fire to ecosystems that have experienced fire suppression or exclusion over the last century. Managing wildfires for resource objectives (i.e., allowing wildfires to burn in the absence of suppression) is an important tool for restoring such fire-adapted ecosystems.

Wildfire risk and hazard: procedures for the first approximation

Publications Posted on: February 25, 2010
This report was designed to meet three broad goals: (1) evaluate wildfire hazard on Federal lands; (2) develop information useful in prioritizing where fuels treatments and mitigation measures might be proposed to address significant fire hazard and risk; and (3) develop risk-based performance measures to document the effectiveness of fire management programs.

Foliar Moisture Contents of North American Conifers

Publications Posted on: February 02, 2007
Foliar moisture content (FMC) is a primary factor in the canopy ignition process as surface fire transitions to crown fire. In combination with measured stand data and assumed environmental conditions, reasonable estimates of foliar moisture content are necessary to determine and justify silvicultural targets for canopy fuels management strategies. FMC values reported in research publications are best used for this purpose.
