Forest Canopy Base Height

LANDFIRE's (LF) Forest Canopy Base Height (CBH) describes the average height from the ground to a forest stand's canopy bottom. Specifically, it is the lowest height in a stand at which there is a sufficient amount of forest canopy fuel to propagate fire vertically into the canopy. These data are provided for forested areas only. CBH unit measurements are meters * 10.

LF 2008 first incorporated Annual Disturbance products into CBH production. The introduction of this information allows for informed changes to the assigned CBH from disturbance type, severity, and time since the disturbance.

For LF Remap, Fuel Vegetation Type (FVT), Canopy Cover (CC) and Canopy Height (CH) is incorporated in place of Existing Vegetation Type (EVT), Existing Vegetation Cover (EVC), and Existing Vegetation Height (EVH) for CBH assignment.

CBH provides information for fire behavior models to determine areas in which a surface fire is likely to transition to a crown fire.
