Back in 2003 the ISW posted about the discovery in Maryland of an ash tree infested with the emerald ash borer (Agrilus planipennis). Now, almost three years later, Maryland's Department of Agriculture has issued a press release stating that the EAB has been found once again in that state. The beetle larvae were discovered in "trap" trees specifically monitored for the presence of the insects. It's good to see Maryland being extra cautious even after so many months with no sign of the invasive insects. The state is now expanding their tree surveys to a much larger area and has instituted a quarantine on all ash trees or any hardwood firewood in Prince George's County, where the beetles were discovered.
