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 The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

Yellow-cedar (Callitropsis nootkatensis (D. Don) Oerst.) is a valuable tree species that is experiencing a widespread decline and mortality in southeast Alaska. This study evaluated the relative importance of several potential risk factors associated with yellow-cedar decline:…

One predicted positive feedback of increasing temperatures in the boreal region is carbon (C) loss through enhanced microbial decomposition of soil organic matter (SOM). The degree to which temperature sensitivity for decomposition varies across a range of C-substrates remains…

Fires in boreal forests frequently convert organic matter in the organic layer to black carbon, but we know little of how changing fire frequency alters the amount, composition and distribution of black carbon and organic matter within soils, or affects podzolization. We…

Laminated sediment (presumed varved) from Greenleaf Lake was examined for evidence of forest fires. A 500-year section dating approximately 770-1270 A.D. was analysed for influx of pollen, charcoal, aluminum, and vanadium using decadal samples. Intervals showing concurrent peaks…

One hundred and sixty-six samples of moose (Alces alces) rumen contents from the Fairbanks and Kenai areas of Alaska were analyzed to quantify regional and seasonal moose habitat interactions in Alaska. We are 95% confident that the frequency of major food items from 44 to 51…

International protocols, such as those of the Montreal Process (MP), specify desired outcomes without specifying the process and components required to attain those outcomes. We suggest that the process and its components are critical to achieve desired outcomes. We discuss…

The frequency of caribou, Rangifer tarandus, crossing of roads, pipeline, and pipelines along roads was studied in the Prudhoe Bay and Kuparuk oil fields on the Arctic Coastal Plain of Alaska. Caribou crossed an elevated pipeline or a road with a frequency similar to the control…

The structure and dynamics of buoyant plumes arising from surface-based heat sources in a vertically sheared ambient atmospheric flow are examined via simulations of a three-dimensional, compressible numerical model. Simple circular heat sources and asymmetric elliptical ring…

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…

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…
