Chapter 6: Monitoring Forest Disturbances across Seasons Using the ForWarn Recognition and Tracking System

National-scale satellite-based forest monitoring can provide uniform and timely insights into forest health. Monitoring across jurisdictions satisfies a basic need, since disturbances such as insects and diseases, wildfire, or severe weather do not respect Federal, State or local boundaries. Monitoring across seasons at high frequency satisfies a second basic need, because early detections can affect the choice of actions that managers take, such as altering the progress of a defoliator or deciding where to prioritize post-disturbance remediation.
