Research Highlights

Damage from Hurricane Michael assessed at high resolution. Purple and red areas are most affected. Damage varied across this timber production landscape, depending on forest age and structure. The background air photo shows conditions in summer of 2017; overlaid color relates vegetation change from winter 2018 to 2019.
