Service State Foresters helping Ohio Landowners
Prepare for the spread of Emerald Ash Borer

The threat of the emerald ash borer (EAB) to Ohio’s ash trees is not going to go away. But two state foresters have been specifically assigned to provide private landowners in 28 central and northern Ohio counties with advice on how to manage their woodlots to minimize the impact of this destructive insect.

Landowners with five or more acres of woodland can work with these foresters to develop a stewardship plan that will describe the ash component on their property, the potential impact of EAB, and how to best prepare for the invasion of this pest.

Those with private woodlots outside of these two regions can contact their Service Forester to obtain information about EAB assistance.
An invasive species from Asia, the insect’s creamy white larvae are up to one-inch in length. They feed on the ash trees’ live tissue under the bark, killing the tree within three to five years.

Notable symptoms/signs of an EAB infestation include: branch die-back, sprouting around the base of the tree; small, D-shaped exit holes in the bark, and – if the bark is peeled back – a serpentine pattern packed with sawdust.

According to data from the U.S. Forest Service, Ohio has more than 254 million ash trees – white, green, blue, black, and pumpkin – that are one-inch in diameter and greater.

Ohio’s first EAB infestation was discovered in Lucas County in 2003. Today, the borer has been found in over 1/3 of the state’s 88 counties.  Click here to view Ohio's current infestation map.
