Changeover from use of the Intermountain Model-8 Burning Index Meter to use of the Spread Index of the National Fire-Danger Rating System required a comparative analysis of both systems. This note describes a program written in SPS to calculate…

Problems being encountered in implementing fire prevention programs were explored by studying the organization for fire prevention at the Fish Lake, Uinta, and Wasatch National Forests in Utah. The study focused on role congruency in fire prevention…

The main purpose of this publication is to summarize the most important aspects of fire behavior as we now know them. The author recognizes that there are still many unknowns in the behavior of forest and range fires. These unknowns will be the…

The investigation of the causes of a fish kill in waters containing ferro‐ and ferricyanide at concentrations far under those generally accepted as non‐lethal have shown these low concentrations to be lethal due to photo‐decomposition and release of…

[Excerpt from text] Measurements of meteorological conditions prevailing during the rapid spread of forest fires are greatly needed so that when their recurrence seems probable, fire weather forecasters may issue warnings of the danger.

[Excerpted from text] It is not often that a large forest fire occurs conveniently near a weather station specially equipped for measuring forest-fire weather. The 13,000-acre Quartz Creek fire on the Kaniksu National Forest…

Risk in the Forest Service. There is risk in everything we do. Risks taken to do our jobs are evaluated individually and collectively multiple times every day. Some actions we take to control risk require very little thought and are based on habit…
Recreation: Social Aspects of Fire: Fire events often have a large impact on recreation and tourism. Local and visiting populations are affected by the impacts, which include short and long-term biophysical effects, indirect effects of fire…
Smokepedia is a continuously updated glossary that defines smoke and air quality terms in the world of wildland fire. The terms and information contained herein come from a variety of sources, including the National Wildfire Coordination Group,…
The objectives of quantifying canopy fuels is to develop practical, validated methods for obtaining quantitative estimates of canopy fuel characteristics, notably bulk density, crown height, and fuel loading, all needed to predict fire behavior and…
FlamMap software creates raster maps of potential fire behavior characteristics (ROS, flame length, crown fire activity, etc.) and environmental conditions (dead fuel moistures, mid-flame wind speeds, and solar irradiance) over an entire FARSITE…
In many forested landscapes across western North America, past fires often act as barriers to fire spread for a time and then, as live and dead fuels accumulate, reburn but with much lower severity than surrounding forested areas. In this project,…
EROS work on fire activity in the United States includes the creation of an atlas of fire perimeters for fires occurring on U.S. National Wildlife Refuges from 1984 through 2013. Fire Atlas perimeter data provide information to refuge managers as…
Firefighter and public safety is the highest priority of fire management activities. The National Park Service incorporates risk management principles into all aspects of our wildland fire program, from planning documents to operational tactics.
The Fire Leadership Toolbox links to the professional reading program, online courses for leadership skills, a staff ride guide and library, a tactical decision games workbook and library, examples of sand tables, standard operating procedures…
In the spring of 2017 the Advanced Fire Environment Learning Unit asked Mark Finney to provide some thoughts regarding different topics related to fire behavior modeling. There are pitfalls analysts can run into when running the models, Mark has…
Wildfire Risk to Communities is a free, easy-to-use website with interactive maps, charts, and resources to help communities understand, explore, and reduce wildfire risk. It was created by the USDA Forest Service under the direction of Congress in…
The Fourth Fire Behavior and Fuels Conference was held in Raleigh, North Carolina, USA, February 18-22, 2013. The theme for this conference was At The Crossroads: Looking Toward the Future in a Changing Environment. Joint sponsorship of the…
