Forest Canopy Cover

LANDFIRE's (LF) Forest Canopy Cover (CC) describes the percent cover of the tree canopy in a stand. Specifically, canopy cover describes the vertical projection of the tree canopy onto an imaginary horizontal surface representing the ground's surface. These data are provided for forested areas only.

A predictive modeling approach relating Landsat imagery and spatially explicit biophysical gradients is used to generate Existing Vegetation Cover (EVC). CC is assigned the midpoint of the EVC forested classes at non-disturbed locations.

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

For LF Remap, Fuel Vegetation Type (FVT), Fuel Vegetation Cover (FVC), and Fuel Vegetation Height (FVH) is incorporated in place of EVC, Existing Vegetation Type (EVT), and Existing Vegetation Height (EVH) in fuel model assignment.

CC is used in the calculation of Canopy Bulk Density and Canopy Base Height. CC supplies information to fire behavior models to determine the probability of crown fire initiation, provide input in the spotting model, calculate wind reductions, and calculate fuel moisture conditioning.
