LANDFIRE's (LF) Forest Canopy Bulk Density (CBD) describes the density of available canopy fuel in a stand. It is defined as the mass of available canopy fuel per canopy volume unit. These data are provided for forested areas only. CBD unit measurements are kg m-3 * 100.
LF 2008 first incorporated Annual Disturbance products into CBD production. The introduction of this information allows for informed changes to the assigned CBD from disturbance type, severity, and time since the disturbance.
For LF Remap, Fuel Vegetation Type (FVT), Canopy Cover (CC) and Canopy Height (CH) in place of Existing Vegetation Type (EVT), Existing Vegetation Cover (EVC), and Existing Vegetation Height (EVH) for CBD assignment.
CBD supplies information for fire behavior models, such as FARSITE, to determine the initiation and spread characteristics of crown fires across landscapes.
