The emerald ash borer (Agrilus planipennis) is a devastating pest of ash trees. For the first time, it has been found outside of its current regulated area in Nova Scotia, Canada.
The continuous spread of emerald ash borer highlights the need for more public education on not moving any ash tree materials. While not currently in Florida, this pest poses a serious threat to Florida ash trees. It is already responsible for the destruction of millions of ash trees in the USA.
