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 The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

Saprotrophic microbes are typically credited with producing extracellular enzymes that recycle organic matter, though roots and mycorrhizal fungi also can contribute and may compete with the saprotrophs. We examined extracellular enzyme activity associated with the…

In this study we characterized spatial heterogeneity of soil carbon and nitrogen pools, soil moisture, and soil pH of the first 15 cm of the soil profile; depth of the organic horizon; forest floor covers; and understory vegetation abundances in three sites (1999, 1987 and 1920…

When white spruce is infested with spruce beetle broods, Dendroctonus rufipennis (Kirby), more beetles are produced than when Lutz and Sitka spruce are infested. In spite of host suitability differences, outbreaks of the spruce beetle have been more frequent and severe in stands…

We observed forage habitat selection in radio-collared moose at feeding sites in southeast Norway. Use of older forest increased from spring to autumn. Birch Betula spp. and bilberry Vaccinium mrytillus accounted for c. 75% of the diet. Occurrence of important forage plants,…

During the summer of 1987, 500-1000 caribou became stranded on Rideout Island in Bathurst Inlet, Northwest Territories. The 40 km2 island did not have sufficient forage to support the animals until freeze-up, and the caribou eventually died from malnutrition after severely…

Alaska yellow-cedar (Chamaecyparis nootkatensis (D. Don) Spach) has been declining and dying for a long, but undetermined, span of time in remote and undisturbed forests of southeast Alaska. Aerial photographs indicate mortality was widespread by 1927. The dates of death for…

Alaska-cedar, Chamaecyparis nootkatensis (D. Don) Spach, has been dying in undisturbed forests throughout southeast Alaska for the last 100 years. To determine if decline spreads, boundaries of mortality at seven sites with decline were mapped using aerial photographs taken in…

The interior of Alaska is a vast area characterized by cold soils which are often underlain by permafrost; a continental climate with great extremes in temperature; and the taiga, a pattern of boreal forest and tundra which is largely the result of past wildfires (Viereck, 1973…

Successional processes within northern Swedish boreal forest are investigated for the last 2000 years by analysis of pollen, charcoal fragments and insect remains preserved in a deep mor humus layer on a small island in a large lake. Frequent disturbances by fire, blow-down,…

A gap model of environmental processes and vegetation patterns in boreal forests was used to examine the sensitivity of permafrost and permafrostfree forests in interior Alaska to air temperature and precipitation changes. These analyses indicated that in the uplands of interior…

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…

A model of carbon and nitrogen cycling developed with ecological relationships from upland boreal forests in interior Alaska was tested with forest structure and forest floor data from several bioclimatic regions of the North American boreal forest. Test forests included black…

Vegetative reproduction, above-ground biomass and nutrient pools, and litterfall and substrate nutrient conditions were evaluated in eastern Ontario immature (age 20 years) aspen (Populus tremuloides Michx. and P. grandidentata (Michx.) ecosystems which had been subjected to the…

Wildfires after prolonged drought consume quantities of fallen trees and soil organic layers. We hypothesized that conflicts within the literature about establishment success of conifers on the resulting ash were a result of the different types of ash used (from wood or peat)…

'The United States obtains approximately 2.7 quads of energy per year from biomass while producing 1.5-3.0 million tons of ash. In the future, energy from biomass should increase to 4 quads, and perhaps it will go as high as 10-20 quads (1). Most of this energy comes from paper…

Consistent success in prescribed underburning requires managers to specify acceptable levels of fire injury and to describe the fuels, weather, and fire behavior necessary to accomplish the objectives. Information is assembled to assist managers in this process. Relationships…

Robinia pseudocacia stem annual growth rings from 1958 to 1987 were analyzed for 14C content. The radioactivity of annual rings was found to be strongly correlated with 14C concentration in the atmosphere, which showed a very sharp rise until 1963 due to nuclear weapon tests…

Carbon uptake by forests is a major sink in the global carbon cycle, helping buffer the rising concentration of CO2 in the atmosphere, yet the potential for future carbon uptake by forests is uncertain. Climate warming and drought can reduce forest carbon uptake by reducing…

Boreal forest fires are an important source of terrestrial carbon emissions, particularly during years of widespread wildfires. Most carbon emission models parameterize wildfire impacts and carbon flux to area burned by fires, therein making the assumption that fires consume a…
