Ash Tree Identification and Emerald Ash Borer Symptom Checklist
Identify Your Tree
Ash trees are easiest to identify when leaves are on the trees; however, it can be identified by looking at the bark in the wintertime.
Leaves oppositely arranged on twig, pinnately compound (leaf is made up of several leaflets attached to a leaf stem), and has 5 to 9 dark green leaflets (usually 7 or 9)
Leaflets either no stalks or very short stalks attached to the leaf stem; smooth or sometimes finely serrated on the upper half
Autumn color green ash yellow and orange; white ash red and purple
Bark young bark is usually flaky; forms tall, interlacing ridges and deep furrows with age
For more information, visit the Ohio Department of Natural Resources web site at www.dnr.state.oh.us .
Check for Symptoms
After you have determined that you have an ash tree, check for the following symptoms:
_____ Have you or your neighbors purchased or received firewood, landscape trees, logs, timber, or branches from Michigan in the last 5 years? (At this time, all EAB finds in Ohio are believed to be directly related to importation of ash tree material from Michigan.)
_____ Distinct, D-shaped exit holes in the bark
_____ Serpentine-shaped tunnels under the bark on the surface of the wood
_____ Young sprout growth clustered at the base of the tree
_____ Unusual activity by woodpeckers
_____ Die-back on the top third of the tree
_____ Vertical splits in the bark
If you answered yes to the first question and your tree has two or more symptoms, contact the Ohio Department of Agriculture at 888-OHIO-EAB or go to www.ohioagriculture.gov .
If the answer to the first question is no, but your ash tree has four of the symptoms (especially the first 3 or 4 listed), you should also contact ODA.
