Tennessee Department of Agriculture.

Three Tennessee counties have been quarantined for Emerald Ash Borer (EAB) after detection of the forest-devastating insect, bringing the total number of Tennessee counties under a state and federal EAB quarantine to 62. Cheatham, Giles, and Maury counties have been added to the list of areas restricted for the movement of firewood, ash nursery stock, ash timber, and other material that can spread EAB. The tree-killing beetle was recently found in these three counties through the United States Department of Agriculture’s EAB detection program.

Note: In 2021, TDA repealed the existing Emerald Ash Borer, Pine Beetle, and Thousand Cankers Disease Quarantines. See current quarantine information.

Humans adores trees. But humans also migrate and trade, habits that led to the accidental introduction of insects and diseases that harm trees and alter the landscape. Examples are easy to find and may be outside your front door: American elms that once dotted streets across America succumbed to Dutch elm disease. Now all colors of ash species – black, green, white, pumpkin, and blue – are threatened by emerald ash borer. The already uncommon butternut tree, also known as white walnut, faces the possibility of extinction from a mysterious attacker. Many invasive insects and fungi come from regions where native trees have evolved to resist their attacks. When these species enter the United States, they find trees that lack this resistance. There's no immediate end to this dismal pipeline, but there is hope on the horizon.

Emerald ash borer (EAB) is an invasive insect from Asia that kills ash trees. EAB was first detected in North America in 2002. Several tiny wasp species are helping to control EAB.

A destructive, invasive beetle that kills ash trees, the emerald ash borer (EAB), has been confirmed in Delaware, making it the 28th state to have found the insect, the Delaware Department of Agriculture announced today. Delaware will be added to a federal quarantine already in 27 other states restricting the interstate shipment of all ash wood and wood products - ash nursery stock, green lumber, waste, compost and chips - as well as hardwood firewood of all species.

Despite the devastating impact of the invasive emerald ash borer on forests in the eastern and midwestern parts of the United States, climate change will have a much larger and widespread impact on these landscapes by the year 2100, according to researchers.

Discover the importance of using local firewood to avoid spreading harmful forest pests. The Don’t Move Firewood campaign is an outreach partnership managed by The Nature Conservancy. The overarching goal of the campaign is to protect trees and forests all across North America from invasive insects and diseases that can travel in or on contaminated firewood. The central tenet of the Don’t Move Firewood campaign is that everyone has a role to play in slowing the spread of invasive tree killing insects and diseases, through making better informed firewood choices. For more information on how you can do your part, please see Frequently Asked Questions.

• Firewood Month Toolkit -- During Firewood Month (October), reduce firewood movement to slow the spread of forest pests and diseases via the firewood pathway.
• Emerald Ash Borer Awareness Weed Toolkit -- During Emerald Ash Borer Awareness Week (May 19-26, 2024) everyone is encouraged to take a few minutes to learn about the signs and symptoms of emerald ash borer infestation on ash trees so that the infestations can be better managed by local tree professionals and foresters.

Native to Asia, the Emerald Ash Borer is an exotic beetle that was unknown in North America until June 2002 when it was discovered as the cause for the decline of many ash trees in southeast Michigan and neighboring Windsor, Ontario, Canada. It has since been found in several states from the east coast spanning across the midwest and in June 2006, we discovered that it had taken up residence in Illinois.

The emerald ash borer is a half-inch long metallic green beetle with the scientific name Agrilus planipennis Fairmaire. Larvae of this beetle feed under the bark of ash trees. Their feeding eventually girdles and kills branches and entire trees. Emerald ash borer was first identified in North America in southeastern Michigan in 2002.

The emerald ash borer (EAB) is a highly destructive invasive beetle which attacks and kills all species of ash, but not mountain ash, which in spite of its name, is a completely different species of tree. To help prevent the spread of EAB, the movement of ash logs and firewood out of regulated areas is restricted. Report any detections outside of regulated areas to the Canadian Food Inspection Agency (CFIA).

Maine Department of Agriculture, Conservation, and Forestry.

The emerald ash borer was found in northern Aroostook County in May 2018, western York County in September 2018, and Cumberland County in September 2019. See the current quarantine areas in Maine.
