The emerald ash borer (EAB) is a new, significant threat to the urban and rural forests of Iowa. First identified in 2002 in southeastern Michigan and recently found in Illinois in 2006, this exotic beetle is responsible for the death and decline of more than 25 million ash trees in southeast Michigan and adjacent parts. It is a great concern because of its close proximity to Iowa and Interstate 80. According to ISU Extension entomologist Mark Shour, Iowa has an estimated 50 million rural ash trees and 10 million urban ash trees that are potentially threatened if and when the EAB enters Iowa. The public needs to be informed as to possible actions to take to prevent its arrival in Iowa, such as preventing the transport of firewood into the state from infested states.
To provide ISU county extension offices, DNR, and other organizations and agencies with display materials to inform the public of this serious threat to landscape trees and forests in Iowa and how they can prevent its arrival.
In January, 2007, three sets of two posters (banners 3 ft X 7 ft), Emerald Ash Borer- Understanding the Threat and The Emerald Ash Borer Dilemma- Knowing Your Insects and Tree, were developed. All county and area Extension offices and other agencies were notified of their availability for free loan and delivery on a first-come, first serve basis. The intended use is for open houses, fairs, field days, and other large, public events. Publications and support material is also available upon request.
In the past six months, EAB posters were used by city foresters and horticulturist, and parks and recreation coordinators, county conservation centers, ISU Extension field crop specialists and county extension education directors for a city expo, county fairs, an Earth Day expo, and an annual child fair. Over 4,000 attending these events viewed the posters. In addition, 200 brochures and 250 fact sheets were mailed. The posters remain in high demand through the next six months.
