EMERALD ASH BORER IN INDIANA

New infestations of emerald ash borer (EAB), a devastating exotic insect pest of North American ash trees, continue to be found in Indiana. As of March 2006, seven counties are quarantined for EAB and ash products: Adams, Hamilton, LaGrange County, Marion, Randolph, Steuben, and Huntington.

Until recently, when an EAB infestation was found in Indiana, the Indiana Department of Natural Resources (IDNR) with funding from the USDA followed a management goal of eradication and removed ash trees in a one-half mile radius of any known infestation. In January 2006, because of limited federal funding for EAB eradication and the difficulty of determining infestation boundaries for eradication projects, the IDNR decided against eradication as a primary management tool and will no longer require nor fund the removal of trees in an infested area. With these policy changes, the IDNR will continue to survey for and monitor EAB infestations to support quarantines and management guidance to landowners.
