Monitoring ash for EAB
EAB Identification
You can help our efforts out by scouting for EAB in forests near you. Report a suspect to the State here and your observations will help inform wood quarantine boundaries and other regulations regarding ash.
However, it is somewhat rare to see the beetle itself on an ash tree. You can identify that an ash tree is hosting EAB if it is showing signs of woodpecker activity, crown dieback, epicormic shoots, d-shaped exit holes and s-shaped feeding galleries underneath their bark. Check out this infographic made by the State, What are the signs and symptoms of an EAB infestation? for more information and pictures.
Help us Monitor Ash for EAB by Participating in the Trap Tree Network
If you have an ash tree on your land, you can help out State monitoring efforts by participating in the Maine Trap Tree Network (view the link for detailed instructions). Through this program you will be asked to girdle an ash tree in May or June, which causes the tree to release stress hormones that attract any EAB in the area. If you choose to participate, please use this on-line form to report it to the Maine Forest Service. You can also reach out at foresthealth@maine.gov or (207) 287-2431 if you have trouble with the form. The Maine Forest Service will follow up with instructions in the fall for processing the tree.
