Emerald ash borers are an invasive species that arrived in the United States from Asia.

Roosevelt Island, which lies between D.C. and Arlington in the Potomac River, recently reopened after the removal of about 200 diseased trees that were under attack by an invasive bug species — the emerald ash borer. The problem isn’t limited to the island: the first emerald ash borer was detected locally in 2003 in Prince George’s County, Maryland. Since then, the ash borer has spread across the region attacking and killing ash trees, which are a significant part of the local tree canopy. Kojo talks with experts about the local battle against the ash borer and how people can protect the trees in their own yards.
