The Emerald Ash Borer

The emerald ash borer is an insect that is rapidly closing in on almost all of North America's ash trees, threatening to destroy all but 0.3% of them, all except for a select species called the blue ash. So, rather than injecting all of our ash trees with pesticides, or chopping them all down, we should look further into this resistant species.

The emerald ash borer kills ash trees by eating the layer underneath the bark of the tree, or the Cambium, but that’s the same thing many native North American insects do. The problem isn’t how the emerald ash borer is killing the ash trees, it’s the circumstances. The emerald ash borer is an invasive species with no natural predators, and since our ash trees have never seen the insect before, they have no defenses yet. Also the emerald ash borer, though it does not move very far on its own, moves easily because of humans.
