Starting in 2017, Seasonal MoD-FIS has provided adjusted fuel model (Scott and Burgan 2005) map data in the Great Basin and Southwest regions based on season specific assessments of herbaceous cover acquired from a comparison of current year Normalized Difference Vegetation Index (NDVI) and Web-enabled Landsat Data (WELD). NDVI values quantify the density of vegetation greenness. Higher NDVIs indicate the presence of more live “green” vegetation, while lower values indicate less live or “brown” vegetation (either not present or dry/dead). These values can fluctuate throughout the fire season and substantially affect fuel availability.

Every year, LANDFIRE analyzes the most recent 10 years of NDVI data to determine the historical average and range of vegetation greenness values for each pixel across the southwest region. These values are correlated with measures of LANDFIRE herbaceous cover to quantify the abundance of fine fuel. A seasonally updated ruleset developed in the LANDFIRE Total Fuel Change Tool (LFTFC), systematically updates static Scott and Burgan Fire Behavior Fuel Model assignments to fuel models that best represent the current fine fuel cover or herbaceous abundance as indicated by the NDVI. Modeling exercises are used to evaluate the final map output.

In addition, MoD-FIS vegetation cover and height products are generated using a current season herbaceous cover layer created from pre-fire season NDVI imagery and LANDFIRE cover data. Seasonal MoD-FIS products are available for viewing and download on the LANDFIRE Map Viewer. Users may also download mosaic layers by available extent and season. See each season's mapped area.
