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:

• Compound leaves with 5 to 9 leaflets
• Leaflets, buds and branches growing directly opposite from one another
• Diamond-shaped bark ridges on mature trees

To see these and other features of ash trees, pass your cursor over the images in the grid below. Or watch the video to have a CSFS urban forester walk you through ash tree identification.
