Maps of invasive annual grasses were created using multi-season Landsat imagery over a 12 years period (2009-2020), and validated using an extensive network of plot data. Annual maps were used to identify persistent and productive populations of invasive annual grass, called hot spots, across entire Mojave Desert ecoregion. The data provided include a 12 band raster geospatial data file (.tiff) that represents classified early season invasive (ESI) grasses for each year from 2009-2020, and a single .tiff file of ESI hot spots made using the Getis-Ord Gi* Hot Spot classification method.
