Preparing for the Emerald Ash Borer in Iowa

G Mark H. Shour, P&S, Entomology


Situation:

The emerald ash borer is a new, significant threat to the urban and rural forests of Iowa. First identified 2002 in southeastern Michigan, this exotic beetle has destroyed millions of ash trees in southeast Michigan, and adjacent parts of Indiana and Ohio, as well as Ontario, Canada. It has also been found in northeast Illinois, as well as nursery trees shipped to Maryland and Virginia. The threat for an Iowa invasion is significant because statewide, there are over 400,000 acres of ash trees (green, white and black) in bottomland and upland forests (2004 USDA Forest Service, forest inventory data).  Moreover, an estimated 20-25% of public trees in Iowa cities are green ash; in some communities (e.g. Cherokee, IA) green ash comprises over 70% of the public trees.

Objective:

To bring together various agencies and organizations to develop a readiness plan that prepares urban and rural forestry stakeholders for the activities and impact of the emerald ash borer. The plan will reduce the likelihood of an emerald ash borer introduction into Iowa, and to find, contain and eradicate emerald ash borer if it arrives. 

Activities/Output:  

A response plan for Illinois was transformed by MH Shour to fit Iowas situations and organizations. Several meetings and drafts of the document brought together the following forestry stakeholders: Iowa Arborists Association; Iowa Association of County Conservation Boards; Iowa Department of Agriculture and Land Stewardship State Entomologists Office; Iowa Department of Natural Resources Forestry Bureau; Iowa Horticultural Society; Iowa Nursery & Landscape Association; Iowa State University; Iowa State University Extension; United States Army Corps of Engineers; United States Department of Agriculture Animal Plant Health Inspection Service, Plant Protection Quarantine; U.S. Department of Agriculture Forest Service; and U.S. Department of Agriculture Natural Resources Conservation Service.

Impact/Outcomes:

The following outputs and outcomes were realized from this project:
