National Research Highlights
Understanding Long-Term Impacts of an Invasive, Tree-Killing Pest
Year: 2019
The emerald ash borer has been killing ash trees in the United States for more than two decades. What does that mean for ash populations and the forest ecosystems? Long-term monitoring plot data collected by USDA Forest Service scientists and partners is helping to elucidate the impacts of this invasive pest and to plan management and conservation strategies.
