Emerald Ash Borer
One of the major concerns of the Ottawa National Forest, at this time, is the invasion of the Emerald Ash Borer (EAB). This exotic beetle from Asia was discovered in July 2002 feeding on ash trees in southeastern Michigan.
Larvae feed in the cambium, between the bark and sapwood, which disrupts transport of nutrients and water in a tree, causing dieback of the branches and eventually death of the tree. Infestations have been confirmed in all or parts of 24 States and the Canadian Provinces of Ontario and Quebec.
Tens of millions of ash trees in forest, rural, and urban areas have already been killed, and many more are rapidly declining from this pest. The broad distribution of this pest in the United States and Canada is primarily due to commerce and the inadvertent transport of infested ash firewood, unprocessed logs, nursery stock, and other ash commodities. Federal and State quaratines now regulate the movement of these products from the infested areas to areas not known to have EAB.
A quarantine has been established which encompasses 83 Michigan counties. View the Emerald Ash Borer Quarantine Map and Fact Sheet here. Possessing, storing or transporting any firewood of any species originating from outside the Upper Peninsula of Michigan is prohibited, please see the Forest Order for more information.

To stop the potential movement of these exotic pests, which are a major threat to Michigan's 19 million acres of forestland, please follow this recommendation:
- Buy or collect firewood once you reach your destination and burn it, do not transport it to another location!
