    Emerald ash borer (A. planipennis) (EAB) has had a devastating effect on ash (Fraxinus) species since its introduction to North America and has resulted in altered ecological processes across the area of infestation. Monitoring is an important tool for understanding and managing the impact of this threat, and the use of common methods by the many groups engaged in monitoring increases the value of monitoring data. We provide detailed methods for monitoring populations of ash trees, emerald ash borers, and lingering ash trees. These comprehensive methods can assist ecologists and managers in understanding the dynamics and effects of EAB infestations. Choice among these methods depends on the scientific and policy questions of interest and the stage of infestation being monitored.
