Phenology-based, remote sensing of post-burn disturbance windows in rangelands

► A novel remote sensing phenology indicator for burned rangelands was developed. ► Indicator was used to evaluate current fire regime changes and post-fire management. ► Contemporary increase in fire season length could influence ecosystem degradation. ► Early season fires resulted in longer time that soils were bare of vegetation cover. ► Reemergence of vegetation did not occur more quickly after post-fire seeding.
