Forest Canopy Height

LANDFIRE's (LF) Forest Canopy Height (CH) describes the average height of the top of the vegetated canopy. CH measurement units are meters * 10. These data are provided for forested areas only.

A predictive modeling approach relating Landsat imagery and spatially explicit biophysical gradients to calculated values of average dominant height from field training sites is used to generate Existing Vegetation Height (EVH). CH is assigned the midpoint of the EVH forested classes at non-disturbed locations.

LF 2008 first incorporated Annual Disturbance products into CH production. The introduction of this information allows for informed changes to the assigned CH 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 Existing Vegetation Type (EVT), Existing Vegetation Cover (EVC), and EVH in fuel model assignment.

CH is used in the calculation of Canopy Bulk Density and Canopy Base Height. CH supplies information to fire behavior models to provide input in the spotting model and calculate wind reductions.
