Crown bulk density
n. The mass of available canopy fuel per unit crown volume (Scott and Reinhardt 2001).
Crown bulk density is a property of an individual tree, not of a plot, stand, or group of trees (see Canopy bulk density). Crown bulk density can be estimated directly using allometric equations or indirectly using separate allometric equations for estimating available crown fuel and crown volume.
Crown bulk density as defined here is not directly used in any fire model (see canopy bulk density); however, methods exist to predict canopy bulk density from crown bulk density.
