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 The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

The antiaggregation pheromone MCH was ineffective in preventing spruce beetle infestation in felled spruce near Hope, Alaska. The lack of reduction in spruce beetle attacks in treated trees is thought to involve a lower than desired elution rate of MCH. Cooler temperatures in…

Agricultural burning in an intensively farmed region within Manitoba's pothole district is shown to affect the nesting activities of ground-nesting ducks. All species, except Blue-winged Teal (Anas discors), preferred unburned nest cover, although success was higher in burned…

There has been considerable interest in the recent literature regarding the assessment of post-fire effects on forested areas within the North American boreal forest. Assessing the physical and ecological effects of fire in boreal forests has far-reaching implications for a…

The uncertainty in carbon emissions from fire was estimated for the boreal region of Alaska over the 50 years of recorded wildfire. Building on previous work where carbon emissions were estimated using a geographic information systems-based model, the uncertainty attached to the…

A study was carried out to assess the variability in trace gas emission from several factors and to estimate the immediate impact of fire on carbon exchange. Using geospatial data, a model of emission was developed for three carbon-based gases, CO2, CO, and CH4, released during…

Previous research has shown that the wet soil conditions found at fire-disturbed sites in the boreal region produce bright backscatter on ERS imagery compared with the surrounding unburned forest. A study was undertaken to examine ERS and standard beam Radarsat imagery over fire…

Studies of ERS-1 synthetic aperture radar (SAR) imagery have shown that fire scars in Alaskan forests are significantly brighter (3-6 dB) than surrounding unburned forest. The signature varies seasonally and changes as vegetation re-establishes on the site over longer time…

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…

This essay discusses three potential models relating disturbance severity to post-disturbance stand composition in the boreal forest: (1) continuous, where changes in disturbance severity cause a proportional and continuous change in stand composition; (2) discontinuous, where a…

The majority of burning in the boreal forest zone consists of stand replacement fires larger than 10 km2 occurring in remote, sparsely populated regions. Satellite remote sensing using coarse resolution (~1 km) sensors is thus well suited in documenting the spatial and temporal…

Biomass burning releases significant amounts of trace gases and smoke aerosol into the atmosphere. This has an impact on the Earth's radiation budget, the magnitude of which has not yet been well quantified. Satellite remote sensing is well suited to assessing the area of…

It has been recently suggested that droughts induced by climate warming reduce the catchment export of colour-forming, and therefore, UV-B protective, dissolved organic carbon (DOC) to boreal lakes, which in turn may influence the health of resident biota. The concentration of…

Intervals between fires, tree blowdowns, and other large and small forest disturbances are often estimated by dating tree rings. Dates are taken from living trees, fallen logs or stumps, or other indicators such as peaks in tree age distributions and ages of understory plants…

This paper shows that there is a reasonable coincidence between the Canada lynx cycle and the occurrence of forest and brush fires. Fires set in motion plant succession, potentially leading to an increase in snowshoe hares (Grange, 1965). Snowfall is also correlated with the…

(1) The Betula papyrifera (paper birch) forest of the wilderness of south-eastern Labrador is described. (2) B. papyrifera forests range in size from less than 1 ha to several km2, display sharp borders with the adjoining conifer forests and are restricted to steep slopes that…

For 21 study sites in the Acadia Forest Experiment Station, near Fredericton, New Brunswick, 34 common understory species were studied to determine the depth of underground plant organs capable of growing shoots. Depth of these plant parts tended to be species specific. These…

Despite increasing temperatures since the end of the Little Ice Age (ca. 1850), wildfire frequency has decreased as shown in many field studies from North America and Europe. We believe that global warming since 1850 may have triggered decreases in fire frequency in some regions…
