LANDFIRE 2024 Existing Vegetation Cover (EVC) CONUS
LANDFIRE's 2024 update (LF 2024) Existing Vegetation Cover (EVC) represents the vertically projected percent cover of the live canopy for a 30-m cell. EVC is produced separately for tree, shrub, and herbaceous lifeforms. Training data depicting percentages of canopy cover are obtained from plot-level ground-based visual assessments and lidar observations. These are combined with Landsat imagery (from multiple seasons), to inform models built independently for each lifeform. Tree, shrub, and herbaceous lifeforms each have a potential range from 10% to 100% (cover values less than 10% are binned into the 10% value). The three independent lifeform datasets are merged into a single product based on the dominant lifeform of each pixel. The EVC product is then reconciled through QA/QC measures to ensure lifeform is synchronized with Existing Vegetation Height (EVH).
In LF 2024, the vegetation products are updated using rulesets similar to LF 2022 Update (https://landfire.gov/data/lf2022) but only for 2024 disturbances since prior disturbances were brought current using machine learning and 2023 satellite imagery during the LF 2023 Update (https://landfire.gov/data/lf2023). LF uses EVC as an input for LF 2024 Fuel Vegetation Cover (FVC).
