How much damage does the Emerald Ash Borer typically do to trees?

The Emerald Ash Borer is known for causing extensive damage to ash trees. This invasive species, native to Asia, primarily targets trees in the genus Fraxinus. When the larvae of the Emerald Ash Borer tunnel beneath the bark, they disrupt the tree's vascular system, which is essential for transporting nutrients and water. This damage often kills the tree within a few years of infestation.

As such, the notion that the Emerald Ash Borer does little to no damage is incorrect. It is one of the most destructive pests in North America, significantly impacting ash tree populations and the ecosystems dependent on them. Therefore, understanding the severe impact of this pest is crucial for forest management and conservation efforts.
