What types of trees does the Emerald Ash Borer affect?
To the best of our knowledge it has only been found on ash trees, hence its name. Trees in wood lots as well as landscaped areas are affected. For the most part, affected trees appear to be at least 2 inches in diameter and larger. NOTE: An ash tree can be identified by its distinctive leaves and bark. Ash trees have several leaves per leaf stem and the leaves are located directly across from each other.
