Learning Lessons from Emerald Ash Borer (EAB)

Perhaps the greatest lesson we can learn from EAB is that it indiscriminately attacked all ash trees irregardless of which species it was. White Ash, Blue Ash, Green Ash, Pumpkin Ash, Black Ash, etc. are all different species of ash and they all have been hit by EAB. The genetic predisposition of all ash trees was similar enough to make room for EAB to thrive.

Next time you decide to plant a tree, don’t just plant multiple different species from the same genus (ie. Red Maple, Sugar Maple, Norway Maple, Freeman Maple, Autumn Blaze, etc.). Consider planting trees from completely different genera altogether such as Gingko, Kentucky Coffee, and Katsura. Such trees are known to have few pest issues and perhaps that is because they stand alone or nearly alone in their very own genus.
