How to measure, describe, and map wildland fuels

Science Spotlights Posted on: September 30, 2015
Researchers with the Rocky Mountain Research Station investigated a number of fuel characteristics across major surface and canopy fuel components that comprise northern Rocky Mountain forest and range fuelbeds. They found that most fuel components have high variability that increases with fuel particle size.

Mastication effects on fuels, plants, and soils in four western U.S. ecosystems: Long-term trends

Projects Posted on: September 16, 2015
Fire managers have increased their use of mastication, the on-site disposal of shrubs and small-diameter trees through chipping and shredding, a practice that alters the chemical and physical conditions of the forest floor and may influence vegetation regrowth for years or decades. We evaluated a network of 18 masticated sites to assess the effects of mastication treatments on plants and soils, and convey how these effects vary over time.

Intercomparison of Fire Size, Fuel Loading, Fuel Consumption, and Smoke Emissions Estimates on the 2006 Tripod Fire, Washington, USA

Publications Posted on: September 09, 2015
Land managers rely on prescribed burning and naturally ignited wildfires for ecosystem management, and must balance trade-offs of air quality, carbon storage, and ecosystem health. A current challenge for land managers when using fire for ecosystem management is managing smoke production.

Wildland Fire Management Research, Development & Application Program

Pages Posted on: August 14, 2015
The Wildland Fire Management Research, Development & Application Program (WFM RD&A) was initiated in 2007 to provide exemplary fire science integration and wildland fire management support to management agencies and partners. The program sponsors and guides the development and application of wildland scientific knowledge, develops decision support tools, and provides science application services to the interagency wildland fire community.

Influence of weather factors on moisture content of light fuels in forests of the northern Rocky Mountains

Publications Posted on: August 12, 2015
The necessity of forest-fire protection is generally recognized in the United Slates. The tremendous damage done by forest fires each year to valuable timber, watershed cover, forest range, wildlife, recreational facilities, and personal property has impressed upon the people the need for preventing and controlling forest fires so far as this is humanly possible.

Measuring forest-fire danger in northern Idaho

Publications Posted on: August 10, 2015
In most of the forest regions of the United States the fire problem is the greatest forest problem. Wasteful methods of logging and lumbering may result in the loss of a large proportion of the remaining forest growth, but the land will usually produce a new crop of timber without undue delay, unless fire occurs.

Do mastication treatments enhance exotic invasive species?

Projects Posted on: April 13, 2015
Mechanical mastication is a fuel treatment that is increasingly prescribed to reduce aerial fuel continuity in forests or to remove encroaching trees in shrublands. Mastication shreds trees and shrubs and distributes the resulting woody debris across the topsoil, moving aerial fuels to the soil surface. This practice can inadvertently create ideal habitat for some exotic plant species that are highly invasive.

Composite Burn Index (CBI) data and field photos collected for the FIRESEV project, western United States

Datasets Posted on: March 27, 2015
This set of Composite Burn Index (CBI) data was collected from 2009 to 2011 and supports several products created during the FIRESEV project, which was funded by the Joint Fire Sciences Program. FIRESEV (FIRE SEVerity mapping tools) is a comprehensive set of tools and protocols to deliver, create, and evaluate fire severity maps for all phases of fire management. This CBI data describes fire effects for the western U.S.

Field measurements of ground, surface, ladder, and crown fuels 2-32 years following Dendroctonus ponderosae epidemics in the Pinus contorta zone of south-central Oregon

Datasets Posted on: March 27, 2015
Mountain pine beetle (Dendroctonus ponderosae, MPB), a bark beetle native to the western North America, has caused vast areas of tree mortality over the last several decades. The majority of this mortality has been in lodgepole pine forests (Pinus contorta) and has heightened concerns over the potential for extreme fire behavior across large landscapes as forest structure and fuels are altered following these MPB epidemics.
