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 The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.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 radiant energy income of a slope influences its ambient temperatures and water movements, both of which are important controls on the growth behaviour, species composition and structure of its vegetation cover. Therefore, information about the radiation environments of…

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…

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 Report is a technical comparison of the American and Canadian systems of forest fire danger rating. It deals with the three fuel moisture indicators in each system, as well as the indexes of spread and energy release or buildup. The final comparison is between the American…

Changing the display format is the least painful way for the fire manager to reduce the cost of AFFIRMS. Some ways to cut costs: •Suppress the headings only if 7 more than three headings can be saved •Pick the shortest display consistent with your needs •Don't use the special…

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…

Spontaneous and piloted ignition of ponderosa pine (Pinus ponderosa Laws.) needles were investigated in an isothermal atmosphere. Four levels of sample moisture content were tested and minimum heat flux intensities required to produce ignition, times to ignition, and surface…

The objective of this work is to illustrate the potential of discrete-event simulation methodologies and object-oriented hierarchical models to simulate landscape dynamics. We formalized the Noble and Slatyer vegetation replacement scheme in a modular, object-oriented formalism…

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 Canadian Climate Centre's General Circulation Model provides two 10-year data sets of simulated daily weather for a large array of gridpoints across North America. A subset of this data, comprised of only those points within the forested part of Canada, was selected for…

This paper examines two sets of decision rules for planning-the economic benefit-cost analysis and the sociological approach-and points the way toward a useful integration. A synthesis provides the means, both conceptual and practical, to aid the decision-maker in selecting…

Normalized difference vegetation index (NDVI) composite image data, produced from AVHRR data collected in 1990, were evaluated for locating and mapping the areal extent of wildfires in the boreal forests of Alaska during that year. A technique was developed to map forest fire…

Surface fire intensity (kW m[-1]) and crown fire initiation were predicted using Rothermel's (1972) and Van Wagner's (1977) models, with fuel data from 47 subalpine conifer stands and 35 years of daily weather (moisture contents and windspeeds). Rothermel's intensity equations…

We have constructed a model for the transient heating of cones showing that there is a logarithmic relationship between the time (sec) to cone opening (releasing viable seeds) or cone ignition and temperature (°K) in the convective column above a fire. The slope of the curve is…

A series of laboratory fire experiments were conducted in fuel beds consisting of either excelsior (wood wool), or 6.35 mm sticks, or a mixture of these. Tests were done both with and without wind. Various characteristics of the fire, including rate of spread and fireline…
