Table 1 Summary data for delayed mortality predictions based on a 5-year NBR decline threshold of 105 in the six study fires in Oregon, Washington, and California. The total area burned and area of delayed mortality exclude non-forest cover and areas that were salvage logged. Areas and percentages in parentheses exclude stand-replacing fire (immediate RdNBR > 828). The delta severity metric (Δ SM) represents the change in severity distributions between one and five years post-fire as measured with the severity metric (Lutz et al. 2011). Larger values indicate greater shifts towards higher levels of burn severity
