Short summary
Alpine treelines reflect the impacts of climate and land use changes on ecosystems. Using low-cost drones and deep learning, we developed a method to map treelines at fine scales across diverse environments. Our results reveal accurate detection and delineation of trees maps over 90 ha of treeline ecotones. This efficient, adaptable approach enables enhanced ecological analyses of treeline processes, aiding global efforts to assess treeline dynamics and their responses to global change.
