Saving the world’s ash forests calls for international cooperation now

Nature Ecology & Evolutionvolume 3pages141144 (2019) | Download Citation

Ash forests in North America and Eurasia are rapidly being lost to two invasive alien species: the emerald ash borer and Chalara ash dieback fungus. We argue that better regulatory policy and science-based intervention can help slow losses, and recommend an international consortium to coordinate science-based intervention.
