These data were compiled for/to estimate predicted pre-fire burn severity for estimating hazard of post-fire debris flow for conservation populations of blue-lineage Colorado River Cutthroat Trout. Objective(s) of our study were to predicted burn severity. These data represent predicted pre-fire differenced Normalized Burn Ratio (dNBR) for portions of Colorado, Utah, and Wyoming and were created for the extent of historic distribution of blue-lineage Colorado River Cutthroat Trout in 2016-2022. These data were created by the U.S. Geological Survey, Southwest Biological Science Center using remote sensing and ecological modeling processes and techniques. These data can be used to compare observations of post wildfire burn severity and/or observed post-fire dNBR for independent validation and for estimating potential post-fire debris-flow in unburned areas.
