Canopy base height (CBH) and canopy bulk density (CBD) are calculated using the program FuelCalc designed by Elizabeth Reinhardt of the Missoula Fire Sciences Laboratory. This program ingests plot data — including species, diameter at breast height (DBH), height, height to live crown, canopy cover, and trees per acre — and computes CBD using species-specific allometric relationships. CBH is assumed to equal the height at which CBD becomes 0.012 Kg m-3. Full descriptions of the CBH and CBD products can be found in the Data Products: National section of this website.
