Two tables prepared for use with the National Fire-Danger Rating System replace 10 tables previously used with the Model-8 Fire-Danger Rating System. They provide for the conversion of Spread Index values at various altitudes, aspects, and times of…

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…

On August 21, 1937, the tragic Blackwater Fire caused the death of 15 firefighters, burning approximately 1,700 acres of National Forest System lands on the Shoshone National Forest, near Cody, Wyoming. An electrical storm occurred in the general…

[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…

Ground, surface, and canopy fuel characteristics serve as essential inputs to computer models of fire behavior and fire effects. FuelCalc is a fuel characteristics simulation software application that calculates initial canopy fuel characteristics…
For thousands of years, the Salish, Pend d’Oreille, and other tribes of the Northern Rockies periodically set fire to the land, pro-foundly shaping plant and animal communities. On this website, you can hear elder interviews and learn about fire…
Wildfire affects the health and well-being of people, yet the science behind its management grapples with uncertainties that have led to sometimes contentious scientific debate. Diverging views over how “natural” high-severity fire is in dry conifer…
This system is intended to assist fire managers and analysts in making strategic and tactical decisions for fire incidents. It is designed to replace the WFSA (Wildland Fire Situation Analysis), Wildland Fire Implementation Plan (WFIP), and Long-…
The primary objective of the National Landslide Hazards Program is to reduce long-term losses from landslide hazards by improving our understanding of the causes of ground failure and suggesting mitigation strategies.
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…
Wildfire directly changes the physical properties of Earth’s critical zone, which leads to catastrophic changes in ecological and hydrological processes (Shakesby & Doerr, 2006). Uncontrolled wildfire in forested headwater catchments often…
The Fire and Fuels Extension (FFE) to the Forest Vegetation Simulator (FVS) simulates fuel dynamics and potential fire behaviour over time, in the context of stand development and management. The Fire Effects Model Extension is a new extension to…
Our Mission: Individuals, neighborhoods, organizations, and agency wildfire professionals working to create Fire Adapted Communities in the Flathead area by providing leadership, technical assistance, education, and resources. We:

This site is hosted by the National Institute for Occupational Safety and Health (NIOSH), which conducts independent investigations of both structural and wildland firefighter line-of-duty fatalities. The website provides access to the NIOSH…
Fire resistance traits drive tree species composition in surface‐fire ecosystems, but how they covary at different scales of variation and with the environment is not well documented. We assessed the covariation of bark thickness (BT), tree height,…
