Ash Tree Identification

Learn How to Identify Ash Trees

The first step to protecting your property from emerald ash borer is determining whether you have ash trees on your property. Key attributes of ash trees include the following:

• Compound leaves with 5 to 9 leaflets
• An opposite leaf arrangement: buds and their leaves and stems grow directly opposite from each other on the branch
• Diamond-shaped bark ridges on mature trees
