AI method reveals millions of dead trees hidden among the living before California's historic 2020 wildfires

University of Copenhagen scientists may have found a new explanation for the California wildfires of 2020. Applying AI to detailed aerial photos, they created a unique dataset detailing mortality down to single trees for all of California State. This revealed individual and clustered tree death spread out among the living on a large scale. The new AI-model will increase understanding of tree mortality and give us a chance to prevent droughts, beetles and flames from destroying the world's forests.
