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 The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

'Two studies were undertaken. An initial study in 1974 produced results that indicated significant losses of nitrogen and some other elements. The study was repeated 1981 as a check on the results of the 1974 burn, and to provide an assessment of the methods used in the first…

'Fires are natural in boreal coniferous forest ecosystems, occuring every 100-200 years. Burning of the humus and forest vegetation (mainly spruce and understory) raises the pH of the humus of the podzolic soil and leads to new succession of the forest plant community. The…

The calculation of heat release rate by oxygen consumption is based on the assumption that all materials release approximately the same amount of heat per unit mass of oxygen consumed. This technique is now being employed to determine the heat release rate of materials in…

The nitrogen-containing products of smog chamber reactions have been the subject of much controversy. Concern has arisen over nitrogen products because of the almost universally poor nitrogen balance reported for irradiated mixtures of hydrocarbons and nitrogen oxides. Some…

We present estimates of nitrogen oxide (NOx) emission from worldwide biomass burning totaling ~13 Tg N yr-1 on a 1 degree longitude by 1 degree latitude grid. Roughly 80 percent of these emissions occur in the zone from 25N to 25 degrees S. The inventory presented here is…

Prescribed burns usually have minimal hydrologic impact on watersheds because the surface vegetation, litter, and forest floor is only partially burned. Wildfire can, however, have a pronounced effect on basic hydrologic processes, leading to the increased sensitivity of the…

Development of humus layer soil microbial biomass C (Cmic) and N (Nmic), fungal biomass (as soil ergosterol content), microbial respiration activity, and the soil organic C (Corg) and N (Ntot) were determined in coniferous forest soils that had received a single prescribed fire…

Fire fighters in Canada's navy must undergo regular training with fires from simulated helicopter crashes. Visible emissions from these fires often create health concerns in surrounding communities. This paper presents air quality implications of plume dispersion associated with…

During a 3-year study, soil microbial biomass C and N, length of the fungal hyphae, soil respiration, and the percent mass loss of needle litter were recorded in coniferous forest soil humus layers following a prescribed burning (PB) treatment or a forest fire simulation (FF)…

Grass fallow shifting cultivation is an important land use practice in the highlands of Bhutan. Part of the nutrient pool contained in soil organic matter is made available for the traditional buckwheat (Fagopyrum tataricum) crop through a highly labor intensive system exposing…

A diffusion flame burner was operated to determine the effect of several parameters on the quality of NOx and unburned hydrocarbons produced. The statistical analysis indicated the unburned hydrocarbon emissions to be dependent upon the rate of heat release in the system, the…

The relative importance of nitrogen inputs from atmospheric depositions and biological fixation is reviewed in a number of diverse, non-agricultural terrestrial ecosystems. Rates of both symbiotic and nonsymbiotic fixation appear to be greater during early succession stages of…

An overdense logdepole pine (Pinus contorta) stand was knocked down and the site was prepared by broadcast burn, windrow burn, or mechanical forest floor removal. Inoculated alsike clover (Trifolium hybridum) was seeded at 0, 10, 20, and 30 kg/ha for the three different site…

The annual species occurring after fire in the chaparral can be loosely grouped into two categories. Generalist species are found in disturbed areas other than burns and these species remain a part of the post-fire flora for up to five years. Fire-specialist species only occur…
