Processed-based fire models: New tools for an era of novel conditions

Publications Posted on: June 17, 2020
The first few years of the 21st century brought a series of unprecedented natural disturbances to the southwestern U.S. A severe drought, later tagged as a “global change type drought,” triggered the mortality of 1,000 of native trees. For some species, such as the ponderosa pine, the drought was especially lethal due to high tree densities which were the outcome, in part, of the impacts of past management practices.

Consequences of an endless summer: Untangling the link between summer precipitation and western wildfires

Documents and Media Posted on: September 25, 2018
Understanding the linkage between decreasing wetting rain days and increased risk of wildfires will enable fuels managers and forest managers to better anticipate wildfire severity and where wildfires may occur. The number of wetting rain days (WRDs) is expected to decrease throughout the West, which could lead to more burned acres. Document Type: Other Documents

BehavePlus fire modeling system: Past, present, and future

Publications Posted on: December 17, 2008
Use of mathematical fire models to predict fire behavior and fire effects plays an important supporting role in wildland fire management. When used in conjunction with personal fire experience and a basic understanding of the fire models, predictions can be successfully applied to a range of fire management activities including wildfire behavior prediction, prescribed fire planning, and fuel hazard assessment.

Evaluation of a Dynamic Load Transfer Function Using Grassland Curing Data

Publications Posted on: February 02, 2007
Understanding and calculating fire behaviour in various fuel types is essential for effective fire management, including wildfire suppression and fuels management. Fire spread in grassland fuel is affected by the curing level, the amount of dead fuel expressed as a percentage of the total (live and dead fuel combined). The influence of live fuel is included in various fire models in different ways. U.S.
