Drone Technology Helps Scientists Detect Early Drought Stress in Trees, Offering New Hope for Forest Protection
Rising temperatures and frequent droughts are placing forests under increasing pressure, making it harder for trees to survive changing climate conditions. Scientists at the Swiss Federal Institute for Forest, Snow and Landscape Research have developed a new method to detect drought stress in trees using drone-based multispectral imaging, allowing them to monitor forest health from the air across large areas.
During the unusually hot summer of 2023, researchers studied how seven native tree species respond to water shortages. Using drones equipped with special cameras, they were able to identify early signs of stress that are not visible to the human eye. These findings could help forestry experts better understand which tree species are more resilient to climate cha...
