Abstract
  • This study analyzes past forest fire behavior on a selected area in the Oregon Cascades in an attempt to evaluate level of fire hazard on selected vegetational areas. Vegetational areas were defined in five broad classes: Merchantable Douglas-fir Stands, Non-merchantable Douglas-fir Stands, Oak- Madrone Stands, Non- forest Lands, and Non-stocked Forest Lands. Rate of spread, difficulty of control, and final size were used as indications of fire behavior. Fire weather severity, slope steepness, aspect, and the vegetational cover type in vicinity of the fire were the environmental factors considered. Five hundred twenty-four fires were sampled in this analysis. The data were fitted to a statistical model for analysis. From this analysis, the importance of the environmental factors on rate of spread, difficulty of control, and final size was tested; tri-variate response surfaces were developed, representing rate of fire spread and difficulty of control according to each vegetational cover type. There were marked differences in the rate of fire spread and resistance to control of a fire in the five generalized cover types studied. Each vegetational cover type, therefore, possesses certain characteristics that suggest a certain level of fire hazard existing during the fire season.
