Basal Area Loss

In the context of RAVG analysis, the percent change in basal area relative to the pre-fire condition. Basal area loss does not describe a permanent loss of basal area within a forest, but simply describes the amount of change in live basal area at the time of assessment. Also called basal area mortality or percent change in basal area.
