The number one way you can stop an insect invasion or pathogen from spreading is by stopping it from ever starting. Who says geneticists and ecologists can’t act in the same way—taking action before a tree is ever in danger?

With ash, proactive and collaborative breeding is already taking place, and it could be a roadmap for the future of combating tree species restorations.
