Landfire Existing Vegetation Cover

Metadata Updated: June 30, 2020

LANDFIRE's (LF) Image Services can be accessed here.EVC is generated separately for tree, shrub, and herbaceous cover lifeforms using training data and other geospatial layers. Percentage tree, shrub, and herbaceous canopy cover training data are generated using plot-level ground-based visual assessments and lidar observations.Once the training data are developed, relationships are then established separately for each lifeform between the training data and combination of Landsat and ancillary data. Each of the derived data layers (tree, shrub, herbaceous) has a potential range from 0-100 percent which are merged into a single composite EVC layer.Disturbance data were used to develop LF Remap products for LFRDB plot filtering and to ensure 2015 and 2016 disturbances were included that were not visible in the source imagery.The EVC product is then reconciled through QA/QC measures to ensure life-form is synchronized with both Existing Vegetation Height and Existing Vegetation Type products.LF uses EVC in several subsequent layers, including the development of the fuel layers.Modeling Dynamic Fuels with an Index System (MoD-FIS)- refined EVH classification based upon current estimates of EVC from Landsat imagery for the current growing season.
