Fire Behaviour In Aspen Slash Fuels As Related To The Canadian Fire Weather Index, M.E. Alexander
Fire Behaviour In Aspen Slash Fuels As Related To The Canadian Fire Weather Index, M.E. Alexander
Aspen Bibliography
The characteristics and short-term results of experimental prescribed fires in 2-year-old trembling aspen (Populus tremuloides Michx.) logging slash in northern Minnesota have been described by D. A. Perala (1974. Can. J. For. Res. 4: 222-228). The associated burning conditions are expressed here in terms of the weather-dependent numerical fuel moisture codes and fire behavior indexes of the Canadian system of forest fire danger rating.
Effects Of Annual Burning On Grassland In The Aspen Parkland Of East-Central Alberta, Howard G. Anderson, Arthur W. Bailey
Effects Of Annual Burning On Grassland In The Aspen Parkland Of East-Central Alberta, Howard G. Anderson, Arthur W. Bailey
Aspen Bibliography
Annual early spring burning has markedly altered the physiognomy and species composition of aspen parkland vegetation of east-central Alberta. Burning was conducted in April for at least 24 years when soil moisture was normally high. The number of herbaceous species per quadrat doubled while a number of woody species declined slightly.

Calibration Of Electric Moisture Meters For Jack And Red Pine, Black Spruce, Paper Birch, Black Ash, Eastern Hemlock, And Bigtooth Aspen, W.L. James
Aspen Bibliography
Direct current electrical resistance and radio frequency power absorption indexes were obtained at a temperature of 80°F, and at moisture content values from about 6 percent to bear the fiber saturation point for seven native American species: jack pine (Pinus banksiana), black spruce (Picea mariana), paper birch (Betula papyrifera), black ash (Fraxinus nigra), eastern hemlock (Tsuga canadensis), bigtooth aspen (Populus grandidentata), and red pine (Pinus resinosa).
