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 The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

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…

Changing climate and land use appear to importantly affect the biosphere by way of impacts on fire regimes. Feedback effects on climate and air quality are likely through emissions of trace gases, aerosols, and particulates that affect radiation budgets, stability of the…

We compared the thermoregulatory capabilities of tropical and subarctic bees to determine whether bees from higher latitudes have greater thermoregulatory capabilities. The data indicate that thermoregulatory capability is a function of size and wing loading, and there is no…

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…

Larvae of the midge Metriocnemus knabi and of the mosquito Wyeomyia smithii feed on decaying invertebrate carcasses inside the water-filled leaves of the purple pitcher plant. I examined the interaction between these two species in natural populations in Gros Morne National Park…

Prescribed burning is being used at Pinery Provincial Park in southern Ontario to restore an oak savanna community which has been changing into a closed oak woodland due to a past policy of fire suppression and conifer reforestation. Quercus muehlenbergii, a shade-intolerant…

To determine whether there are persistent differences in fire frequency in Picea glauca and Pinus banksiana forests, we examine dendrochronological and palynological records of fire history. The time since the last fire at 165 stands located in Wood Buffalo National Park (44,807…

In circumstances where species vie for limited resources, disturbance can preclude competition by lowering population densities and thereby relieving pressure on resources. For that reason, competition is believed to be unimportant in the establishment of plant seedlings…

The problem of fire protection in the urban/wildland interface is a complex combination of three components: fire behavior and combustion, social and political factors, and the cooperation of property owners. By examing the problem's component parts, it is easier to understand…

This study assessed the variability of sample estimates for downed and dead woody fuel weight in natural lodgepole pine (Pinus contorta Dougl) stands using line-intersect sampling procedures. Equilateral triangles (30 m/side) were established at each of 40 sample sites with…

To determine the effect of stage of bud development on heat tolerance, overwintered black spruce seedlings (Picea mariana (Mill.) B.S.P.) were (i) maintained in a dormant state, (ii) allowed to grow new shoots under favorable greenhouse conditions, or (iii) induced to initiate…

The Kirtland's warbler (Dendroica kirtlandii) is an early succession, area-sensitive species seldom found in stands smaller than 30 to 40 ha. This warbler occupies dense jack pine (Pinus banksiana) stands where trees are from 6 to 23 years old and from 1.7 to 5.0 m high growing…

In many cases, fire is not an effective thinning tool. However, under certain conditions, stand density and composition can be manipulated by the prescribed use of fire. The factors that determine tree survival are reviewed along with how to effect changes in the fire situation…

This report describes use of increment borers for interpreting fire history in coniferous forests. These methods are especially useful in wildernesses, parks, and other natural area where fire history is needed for fire management planning, but where sawing cross-sections from…

The effect of climate on tree rings may change over time as a result of stand dynamics or environmental stress. These dynamic effects can be studied using theory and computer programs and further information on their use are availabe from the authors.

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…

An extension of the simple ellipse model of a vegetation fire is presented. This facilitates numerical implementation, and can therefore incorporate irregular topographical features and temporal changes in burning conditions. The model has been encoded into an interactive PC…

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…
