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 The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

Major patterns of plant communities and species distribution are induced by various disturbance regimes operating at a different spatial and temporal scales (Loucks 1970; White 1979; Bormann & Likens 1979b; Delcourt, Delcourt & Webb 1983). The development of temperate…

Forest insect and disease populations and related damage increased throughout Alaskan forests in 1991. Spruce bark beetle populations increased for the third consecutive year. 375,000 acres were impacted in 1991. Hardwood defoliator activity increased for the second year and…

[Intro first paragraph] Human activities are increasingly affecting the relation between the biota and the physical environment. That has long been true of resource developments that have transformed vegetation on a regional scale. Now, however, the scale of human influence has…

Techniques are described for locating and estimating the areas of fires in the boreal forests of Alaska using satellite imagery from the Advanced Very High Resolution Radiometer (AVHRR). The basis for these techniques is the normalized difference vegetation index (NDVI) derived…

An improved method to estimate the amounts of carbon released during fires in the boreal forest zone of Alaska in 1990 and 1991 is described. This method divides the state into 64 distinct physiographic regions and estimates areal extent of five different land covers: two forest…

Initial observations on effects of wildfires in black spruce [Picea mariana] forests in Alaska on radar backscatter are presented. Airborne and spaceborne SAR imagery are utilized to illustrate two distinct fire signatures. A theory is presented to explain these differences.

Models for moose density were developed using subsets of remotely sensed habitat variables in north-central Alaska. Macro-habitat factors explained from 60-70% of the variation in November moose densities using a regression model. Use of logistic regression allowed correct…

The spruce beetle, Dendroctonus rufipennis (Kirby), has had a major effect on the spruce forests of southcentral Alaska. In one area of the Chugach National Forest, 51% of the Lutz spruce, Picea lutzii Little, or nearly 90% of the commercial stand volume was killed by spruce…

Heart rot fungi cause substantial economic loss in many forests, but their ecological roles in altering the speed or direction of succession are frequently overlooked. As heart rot induces trees to die standing or, more commonly, by bole breakage, the fungi that cause heart rot…

Success of spruce beetle attacks in pruned and unpruned boles of Lutz spruce in south-central Alaska
Pruning live branches from different heights and sides on the boles of long-crowned Lutz spruce (Picea + lutzii Little) baited with frontalin reduced successful spruce beetle (Dendroctonus rufipennis Kby) attacks in pruned sections of most trees. The benefits of pruning seemed…

The impact of competitors, parasites and predators on spruce beetle Dendroctonus rufipennis (Kirby) broods was studied at an endemic population site near Fairbanks, Alaska, as well as at an epidemic area near Summit Lake and Cooper Landing. Logs of white spruce, Picea glauca (…

The results of a study using satellite imagery to map boreal forest fires in Alaska in 1990 and 1991 are presented. Composite AVHRR data detected >80% of fires greater than 2000 ha in size. Additionally, using a two season method, 78% of the area of all boreal forest fires in…

Taiga dominates the northern two-thirds of Sweden. In the province of Halsingland it covers 83% of the land area, but only 0.01% of this is virgin forest. The vascular flora of the main part of the taiga is dominated by a few species. Scots pine (Pinus sylvestris) and Norway…

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…

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…

Wildfire in the boreal forests at the Experimental Lakes Area in Ontario caused significant losses of nitrogen and phosphorus in streams. Both watershed type and fire intensity appear to determine the extent of losses. The Northeast wetland basin lost more N and P, especially…

'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…
