Common questions about the Emerald Ash Borer

How do I identify an Ash tree?
Ash trees have an opposite leaf arrangement  (leaves and buds are located directly across from each other). Ash leaves are compound and typically consist of five to 11 leaflets. The edges of the leaflets may be smooth or toothed. Mature ash bark is rough and blocky, with a nearly diamond-shaped pattern. Younger trees have smoother bark. When seeds are present, they appear in paddle-shaped clusters that stay on the tree until late fall or early winter.Emerald Ash Borer on a penny
