There is little doubt that fire effects are greatly
dependent upon fire behavior. Because there are many
aspects of fire behavior, there are also many quantitative
descriptors. The fire-behavior characteristic(s) selected
as a correlation parameter must have a logical relationship
to the effect being studied. For example, nutrient
effects are probably best gauged by the degree of fuel
consumption, a measure directly related to the quantity
of organic matter ashed by the fire process (Van Wagner
and Methven 1978).
