We describe a model that estimates the optimal total expected cost of a wildland fire, given uncertainty in both flame length and fire-line width produced. In the model, a sequence of possible fire-line perimeters is specified, each with a forecasted...
Alaska Reference Database
The Alaska Reference Database originated as the standalone Alaska Fire Effects Reference Database, a ProCite reference database maintained by former BLM-Alaska Fire Service Fire Ecologist Randi Jandt. It was expanded under a Joint Fire Science Program grant for the FIREHouse project (The Northwest and Alaska Fire Research Clearinghouse). It is now maintained by the Alaska Fire Science Consortium and FRAMES, and is hosted through the FRAMES Resource Catalog. The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.
PLUMP is a general-purpose, one-dimensional plume rise model for wildfire and prescribed fire planning. It calculates the characteristics of fire plumes, including vertical velocity, water content, excess temperature, rain, and ice. The model can also...
This paper is intended to broaden awareness and help develop consensus among USDA Forest Service scientists and resource managers about the role and significance of disturbance in ecosystem dynamics and, hence, resource management. To have an effective...
Fire management of grasslands is best executed based on an understanding of the fundamental properties of grassland components, structures, and environments, and the nature of fire behavior in grassland fuels. The art of controlled burning combines...
A new Forest Service policy, effective February 1978, allows some wildfires to burn under prescribed conditions, urges a multidisciplinary approach to fire control, and has applications to rural and urban situations.
A nylon tent designed for firefighters was placed in a smoky environment in a wind tunnel. The close knit fabric screened out 95 percent of the particulate matter but none of the gases in the smoke. There was no oxygen depletion in the tent when a...
Spontaneous and piloted ignitions of rotten wood samples from ponderosa pine (Pinus ponderosa) Douglas-fir (Pseudotsuga menziesii) and subalpine fir (Abies lasiocarpa) were investigated in a specially designed ignition furnace. Minimum heat flux...
This conference brought together scientists and managers from federal, state, and local agencies, along with private-sector interests, to examine key concepts involving sustainable ecological systems, and ways in which to apply these concepts to...
There are four major questions affecting the future of ecological restoration. The first and most serious question is philosophical. Should we attempt to restore ecosystems? Some people want to separate humans from nature because they believe that...
Effects of wind velocity and slope on fire spread rate and flame length were examined. Fuel beds of vertical sticks (13.97 cm x 0.455 cm x 0.1 10 cm) and coarse excelsior were burned in an open-topped tilting wind tunnel. Mean fuel moisture content of...
