National Vegetation Classification

LANDFIRE's (LF) National Vegetation Classification (NVC), a new existing vegetation layer, represents the current distribution of vegetation groups within the U.S. National Vegetation Classification circa 2016. These groups are defined as combinations of relatively narrow sets of diagnostic plant species, including dominants and co-dominants, broadly similar composition, and diagnostic growth forms.

The NVC product also includes ruderal or semi-natural vegetation types. The LF Ruderal NVC Groups Descriptions for CONUS provides descriptions for each ruderal NVC Group including species, distribution and classification information.

NVC groups are mapped using decision tree models informed by field reference data, Landsat imagery, elevation/topographic, and biophysical gradient inputs.
