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 The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

From the Introduction ... 'It is a well known fact that the presence of moisture exerts considerable influence on the difficulty of ignition and the subsequent rate of combustion of forest fuels. Its effect on ignition is primarily a result of the fact that the water must be…

Modelling of the wind effect on the rate of spread of a flame in a forest fire usually employs a wind velocity measured at mid-flame height. An alternative formulation is proposed in this paper, based on the wall shear-stress produced by the wind on the fuelbed in the absence of…

The forecast skill of the National Meteorological Center's medium range forecast (MRF) numerical forecasts of fire weather variables is assessed for the period June 1, 1988 to May 31, 1990. Near-surface virtual temperature, relative humidity, wind speed and a derived fire…

The Minimum Acceptable Visibility (MAV) table was originally provided by the California Highway Patrol in response to an inquiry relative to acceptable highway visibility reduction caused by smoke. The table was included in chapter two of the 1991 edition of the National Park…

From the text...'The measurement of temperature in forest fires is complicated by the tendency of thermocouples to radiate heat to cooler surroundings outside the flame, and thus to register less than the true flame temperature. In the United States, this problem has been…

The tables presented here contain forest fire statistics for the calendar year 1984, 1985, 1986, and 1987 as reported by all Canadian forest fire control agencies. The statistical data are presented separately for each province or other major jurisdiction, and for Canada as a…

Lightning causes one third of the 9000 wildfires that occur in Canada. Annually, these lightning-caused fires account for 90% of the area burned and cost Canadians at least 150 million dollars in suppression costs and values destroyed. Unlike the fires caused by human negligence…

Breeding bird populations were monitored for three years after an October prescribed burn in a fescue grassland near Saskatoon, Saskatchewan. Breeding populations of 12 species were recorded on a 12.9 ha burned plot and an adjacent 5.6 ha unburned plot, each with similar…

Prescribed fire has traditionally been used to create and maintain Elk habitat in the Tuchodi River area of northeastern British Columbia. Elk use of post fire vegetation was examined. Elk wintered primarily on younger postburn vegetation dominated by grasses or shrubs, except…

This paper looks first at the kind of forest fire statistics that are currently available in Canada. The main statistics are number of fires area burned, causes, and control costs. Good inventory data on burned areas are not available. The recent rising trend in national burned…

Because cribs of wood are widely used to produce experimental fires it is sometimes necessary to predict their burning behavior especially when their burning rate is not controlled primarily by some other factor such as the window opening in a compartment. If the window is large…
