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 The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

Species diversity in the Arctic varies dramatically across abiotic gradients, including topography, moisture, pH and nutrient availability. We hypothesized that vascular plant species density, richness and diversity in Alaskan tundra would be correlated with: (i) site age, (ii)…

Evaluating the effects of prescribed fire and wildland fire requires a greater understanding of the fire behavior of organic soils. Determining the ignition limit of organic soils over a wide geographical area is the subject of this study. Side ignitions were attempted with an…

Smoldering ground fires spread slowly (about 3 cm h-1) and can raise mineral soil temperatures above 300 degrees C for several hours with peak temperatures near 600 degrees C, resulting in decomposition of organic material and the death of soil organisms. Smoldering ground fire…

Laboratory experiments were conducted to investigate how both mineral soil and moisture content affect the smoldering combustion in forest duff. Peat was used to represent the fermentation and humus horizons (Oe and Oa soil horizons) of a coniferous forest floor nominally called…

Patterns of disconnected fuel treatment patches that overlap in the heading fire spread direction are theoretically effective in changing forward fire spread rate. The analysis presented here sought to find the unit shape and pattern for a given level of treatment that has the…

This paper reviews methods used for testing the fit of the cumulative form of a negative exponential distribution to the cumulative distribution of forest age-classes. It is shown that existing methods can lead to a greater chance of falsely rejecting the fit of the negative…

Fine-root (diameter 10 mm) standing biomass, length, distribution, production, and decomposition were studied in mixed conifer/broadleaved forest stands 48, 122, and 232 yr after fire on clay soils in the southern boreal forest of Quebec. A combination of ingrowth bags, soil…

Wildland fire is the dominant large-scale disturbance mechanism in the Alaskan boreal forest, and it strongly influences forest structure and function. In this research, patterns of burn severity in the Alaskan boreal forest are characterised using 24 fires. First, the…

Fire is the keystone disturbance in the Alaskan boreal forest and is highly influenced by summer weather patterns. Records from the last 53 years reveal high variability in the annual area burned in Alaska and corresponding high variability in weather occurring at multiple…

Emissions from forest fires in Alaska and the Yukon Territory were observed at Chebogue Point, Nova Scotia (43.7°N, 66.1°W), between 11 and 13 July 2004. Smoke aerosols were first detected in the free troposphere by a Raman lidar and extended up to 8 km altitude. The plume was…

The redistribution of nutrients after fire was examined under laboratory conditions by igniting samples of spruce needles, birch leaves and lichen and leaching the ash through a soil column. Nitrogen was lost from the tissue samples at temperatures above 200 deg C, and 52-88% of…

A model was developed to predict the ignition of forest crown fuels above a surface fire based on heat transfer theory. The crown fuel ignition model (hereafter referred to as CFIM) is based on first principles, integrating: (i) the characteristics of the energy source as…

The rate of spread of crown fires advancing over level to gently undulating terrain was modeled through nonlinear regression analysis based on an experimental data set pertaining primarily to boreal forest fuel types. The data set covered a significant spectrum of fuel complex…

The unknowns in wildland fire phenomenology lead to a simplified empirical model approach for predicting the onset of crown fires in live coniferous forests on level terrain. Model parameterization is based on a data set (n=71) generated from conducting outdoor experimental…

Application of crown fire behavior models in fire management decision-making have been limited by the difficulty of quantitatively describing fuel complexes, specifically characteristics of the canopy fuel stratum. To estimate canopy fuel stratum characteristics of four broad…

Boreal regions are an important component of the global carbon cycle because they host large stocks of aboveground and belowground carbon. Since boreal forest evolution is closely related to fire regimes, shifts in climate are likely to induce changes in ecosystems, potentially…

Diversity of passerine birds and mammals was estimated in well-drained areas located at proximity of the hydroelectric reservoir La Grande-3, where natural fire regime still prevails in the absence of forest exploitation. Forest stands were divided up into four post-fire stages…

The range used for calving and for the first month of lactation by the Riviere George Caribou Herd (RGH), which peaked at over 600,000 individuals in the mid-eighties, showed signs of overgrazing, in contrast to that used by the adjacent Riviere aux Feuilles Herd. Density of…
