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 The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

Forest fires can be divided into two broad classes-wildfires and prescribed fires. Wildfires, whether caused by nature (lightning, etc.) or by the accidental or malicious acts of man, are not planned by forest managers and do not occur under controlled conditions. They can be…

The major condensible products (-45ºC) from smoldering combustion of ponderosa pine sapwood have been identified and quantified. Methylene chloride extracts of the condensate, as well as nonextracted condensate, were analyzed by gas chromatography/mass spectrometry (GC/MC). Non-…

Chemicals from glowing fires in highly decayed conifer logs may be useful for detection of small fires by spectroscopic methods. Two major chemical constituents were tentatively identified as methanol and furfural (2-furaldehyde). Additional materials tentatively identified were…

Today biomass burning is accepted to be an important source of many trace gases affecting atmospheric chemistry (Crutzen et al., 1979; Cofer et al., 1988a; Radke et al., 1988; Crutzen et al., 1990). Despite its global significance and in contrast to fossil fuel use, where…

BIOMASS burning is a primary source of many trace substances that are important in atmospheric chemistry. More than 80% of the world's biomass burning takes place in the tropics as a result of savanna fires, forest-clearing activity, and the burning of agricultural waste and…

Emission factors for several trace gases were determined using airborne measurements from 13 biomass fires in North America. Emissions of methane (CH4), nonmethane hydrocarbons (NMHC), hydrogen (H2) and ammonia (NH3) were found to be positively correlated with the ratio of…

Agricultural practices and land use modification were estimated to produce 14% and 9%, respectively, of the total greenhouse gas emissions contributing to global warming in the decade preceding 1990 (Marshall, 1989). Carbon release rates from tropical forest conversion have been…

We used an airborne Fourier transform infrared spectrometer (AFTIR), coupled to a flow-through, air-sampling cell, on a King Air B-90 to make in situ trace gas measurements in isolated smoke plumes from four, large, boreal zone wildfires in interior Alaska during June 1997.…

Open sources are those stationary sources of air pollution too great in extent to be controlled through enclosure or ducting. Open sources of atmospheric particles include: wind erosion, tilling, and prescribed burning of agricultural cropland; surface mining and wind erosion of…

Ecosystems driven by wildfire regimes are characterized by fire size distributions resembling power laws. Existing models produce power laws, but their predicted exponents are too high and fail to capture the exponent's variation with geographic region. Here we present a minimal…

Climate change appears to be altering boreal forests. One recently observed symptom of these changes has been an apparent weakening of the positive relationship between high-latitude boreal tree growth and temperature at some sites (D'Arrigo et al 2008). This phenomenon is…

For millennia, peatlands have served as an important sink for atmospheric CO2 and today represent a large soil carbon reservoir. While recent land use and wildfires have reduced carbon sequestration in tropical peatlands, the influence of disturbance on boreal peatlands is…

Twenty-five C-band Radarsat-1 synthetic aperture radar (SAR) images acquired from the summer of 2002 to the summer of 2005 are used to map a 2003 boreal wildfire (B346) in the Yukon Flats National Wildlife Refuge, Alaska under conditions of near-persistent cloud cover. Our…

Understanding the relationship between species diversity and productivity is central to linking compositional and functional aspects of terrestrial ecosystems, and little is known about such issues in boreal forests. We used structural equation modelling (SEM) to test several…

Recent warming at high-latitudes has accelerated permafrost thaw in northern peatlands, and thaw can have profound effects on local hydrology and ecosystem carbon balance. To assess the impact of permafrost thaw on soil organic carbon (OC) dynamics, we measured soil hydrologic…

A new algorithm for mapping burned areas in boreal forest using AVHRR archival data Long Term Data Record (LTDR) (0.05°, ca. 5 km, version 3) was developed in Canada using burn records for the period between 1984 and 1999 and evaluated against AVHRR 1 km and AVHRR-PAL 8 km…

Fire is an important disturbance in the forest ecosystems of Canada. On average, 18,471 km^2 of forest burn annually, 92% of which burns within the boreal forest. Due to the long history of fire in the boreal forest, many boreal tree species have evolved to rely on fire to…
