Short summary
Tree falls along power lines cause safety, cost, and environmental issues. Drones can map individual trees to improve risk management. We applied the ForestGALES wind-risk model to individual trees along power lines in southern Norway. It performed moderately alone but combining it with machine learning greatly improved accuracy, offering managers precise guidance for safer vegetation management.
