Hosts:

In North America, all 14 types of North American ash trees are equally vulnerable to attack by emerald ash borer.

 

Commodities Affected:
Forestry and Natural Areas, Nursery, Ornamentals, and Turf

 

Threat:

Emerald ash borer kills ash trees throughout eastern North America affecting upland, mesic, and wetland habitats, in addition to rare and threatened Fraxinus species. Represent threats to approximately 300 million ash trees in Indiana, and 8 billion ash trees in the forests in North America, at an estimated value loss of $20 to 60 billion dollars nationally (USFS statistics). Estimates of costs incurred by Indiana residents, cities and towns could be as much as $90 billion over the next 25-30 years.

 

Distribution:

Emerald ash borer is known to occur in 14 Indiana counties: Adams, Allen, DeKalb, Hamilton, Huntington, Lagrange, Marion, Porter, Randolph, St. Joseph, Steuben, Wells (03-19-2007), White, and Whitley (05-09-2007). In the U.S., emerald ash borer is known to occur in various Ohio counties and all of lower Michigan. (See <www.emeraldashborer.info> for updates). Originally known from eastern and southeastern Asia, including, e.g., China, eastern Mongolia, far eastern Russia, Japan, and Korea among others.
