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 The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

The 'bloom' of annual and perennial plants following fire in the chaparral is well documented, but there is controversy over what factors cause this burst of new growth. I examined the relative importance of fire, competition, and herbivory in seedling germination and…

The Mann Gulch fire, which overran 16 firefighters in 1949, is analyzed to show its probable movement with respect to the crew. The firefighters were smoke-jumpers who had parachuted near the fire on August 5, 1949. While they were moving to a safer location, the fire blocked…

Modelling of the wind effect on the rate of spread of a flame in a forest fire usually employs a wind velocity measured at mid-flame height. An alternative formulation is proposed in this paper, based on the wall shear-stress produced by the wind on the fuelbed in the absence of…

The forecast skill of the National Meteorological Center's medium range forecast (MRF) numerical forecasts of fire weather variables is assessed for the period June 1, 1988 to May 31, 1990. Near-surface virtual temperature, relative humidity, wind speed and a derived fire…

Lightning causes one third of the 9000 wildfires that occur in Canada. Annually, these lightning-caused fires account for 90% of the area burned and cost Canadians at least 150 million dollars in suppression costs and values destroyed. Unlike the fires caused by human negligence…

Studies of anticipated effects of global warming tend to concentrate on the physiological limits of individual organisms, and imputed modifications to biome distributions expresed as climax ecosystems. Changes in distributions of individual species and of tree species…

We develop a simple analytical model to estimate the thickness of a smoke layer formed by a plume of a large area fire and to account for crosswinds. We take advantage of the dominant flow features in the upper part of the rising plume and in the smoke layer far from the plume…

We correct the variance for the rate of spread of a fire through a non-homogeneous fuel as described in Catchpole et al. (1989, Ecol. Modelling, 48: 101-112). The spatial dependence of the fuel types can greatly influence this variance; a phenomenon not expressed by the analysis…

This paper looks first at the kind of forest fire statistics that are currently available in Canada. The main statistics are number of fires area burned, causes, and control costs. Good inventory data on burned areas are not available. The recent rising trend in national burned…

This is a review of the essential ingredients needed to make a mathematical model of fire spread through a fuel bed. The physical problem is outlined in general terms. Previous models are classified as statistical, empirical, or physical in accordance with the methods used in…

Equations for predicting duff and large woody fuel (7.6+ cm) consumption are summarized. Dependent variables are duff depth reduction, percentage duff depth reduction, percentage mineral soil, large fuel diameter reduction, and percentage large fuel reduction. Opportunities to…

Predictions of soil heating for two models were compared with temperatures and moisture contents measured in laboratory experiments. Columns packed with soil of different water contents and bulk densities were placed under a radiant gas heater. Temperature and water content were…

The moisture content of the litter is one of the most important environmental factors affecting the ignition and propogation of a forest fire. The concept of equilibrium moisture content has proven utility in making a meaningful connection between weather and litter moisture.…

Fire managers currently use simple elliptical models to predict the perimeter of a fire when the fire starts from a single point. However, when examined closely wildland fire perimeters are highly irregular. We tested the hypothesis that a fire is actually fractal in nature and…

Knowledge of fire behavior is critical for those who control wildfires. Fire managers must know spread rates and intensity-not just to eventually contain and extinguish the fire but also to keep their fire control personnel safe. Managers realize that weather is paramount in…

We describe a mathematical model for the probability that a fireline succeeds in containing a fire. The probability increases as the fireline width increases, and also as the fire's flame length decreases. More interestingly, uncertainties in width and flame length affect the…

Traditionally, in the Southwest, ponderosa pine (Pinus ponderosa) red slash has not been treated with fire to meet resource objectives until all slash has fully cured, usually a 2-to-4-year wait. Waiting for slash to cure is still the widespread practice on most forests in the…

A prescribed fire was ignited near Chapleau, western Ontario, Canada, on the afternoon of August 10, 1989. The fire, covering approximately 400 ha, burned vigorously over a period of 3 hours, from 1400 to 1700 EDT, generating a plume cloud structure including a portion…

Spatial changes in tree and upland tundra cover in response to a complex environmental gradient and to landscape factors were investigated in the high subarctic forest-tundra of NW Canada. Vegetation and terrain studies provided ground truth for a grid of 1314 air photos which…

The acceleration phase of a forest fire, from ignition to the equilibrium rate of spread, is perhaps the most important phase of fire behavior because often it represents the only time period in which suppression efforts could be effective. A series of experimental fires in a…
