A visualization tool that tracks changes to the nation's forests in near-real time is helping resource managers pinpoint areas with the most damage from Hurricane Helene in the US Southeast.
The ForWarn visualization tool was co-developed by the Department of Energy's Oak Ridge National Laboratory with the U.S. Forest Service. The tool captures and analyzes satellite imagery to track impacts such as storms, wildfire and pests on forests across the nation.
When staff with the Forest Service's Eastern Forest Environmental Threat Assessment Center in Asheville, North Carolina, were unable to work in the immediate aftermath of Helene due to utility outages, the ORNL-hosted ForWarn system continued monitoring the storm's impact and providing reports. ForWarn indicated areas of severe disturbance to the forest canopy that were later confirmed by aerial photography.
"ForWarn helps quickly identify areas that may need remediation such as timber harvesting or prescribed burns as piles of felled trees dry out and potentially pose wildfire hazards," said ORNL's Jitendra Kumar.
