On October 20, 2008, Cleveland Metroparks Forestry Division staff encountered the first confirmed Emerald Ash Borer (EAB) infestation in the Park District along Big Creek Parkway south of Bagley Road. Follow-up inspections by Natural Resources Division staff determined that the infestation might span an area from Baldwin Lake northeast towards the Kiwanis Drive intersection along Big Creek parkway. In April 2008, a notable population of EAB was confirmed adjacent to Park District property in the vicinity of Brecksville and Broadview Heights near Seneca Golf Course and the Ohio Turnpike Plaza.
The USDA Forest Service has been collecting seed from all species of ash for long-term storage and future research. Cleveland Metroparks, the Holden Arboretum, Lorain County Metroparks, Lake Metroparks, and Geauga Park District are participating in the project by helping collect seed from ash trees in the region. Background information on the Forest Service's ash seed collection program can be found here.
Ohio Department of Agriculture Expands Emerald Ash Borer Quarantine - 1/14/10
Emerald Ash Borer Background
The Emerald Ash Borer is a small but destructive exotic beetle from Asia. It was first discovered in July 2002 feeding on ash trees in southeastern Michigan, probably arriving in wooden packing material at a harbor near Detroit. Evidence suggests that the Emerald Ash Borer has been established in Michigan for at least ten years. More than 3,000 square miles in southeastern Michigan are infested and more than 6 million ash trees are dead or dying from this pest.
Metallic green in color, EAB adults measure 1/2 inch in length and 1/8 wide. The average adult beetle can easily fit on a penny. Adult beetles lay eggs in the bark of any ash species (White, Green, Black, Blue), and after hatching, larvae feed in the cambium between the bark and wood. Larval feeding results in galleries that eventually girdle and kill branches and entire trees.
Emerald Ash Borer was identified in Ohio in February 2003. Since then, it has moved progressively across the state, and on October 3, 2006 the Ohio Department of Agriculture (ODA) confirmed the presence of emerald ash borer (EAB) in Cuyahoga County. Subsequently, ODA to placed the county under EAB quarantine prohibiting the movement of harvested ash wood products, including firewood, from quarantined counties into non-quarantined counties. The Ohio Department of Agriculture EAB web page has up to date information and distribution maps concerning EAB in Ohio.

The USDA Animal and Plant Health Inspection Services have additional information about EAB and the quarantine.
