Encyclopedia Article

 

Map of Iowa showing current distribution of confirmed EAB infestations as of April 10, 2018.

Brown circles on the distribution map indicate a 15-mile radius around confirmed discoveries of EAB.  Ash trees within 15 miles of a confirmed EAB site are considered to be at risk of attack and preventive treatments are suggested for healthy, vigorous and valuable trees within this risk zone.  It may be premature to treat ash trees outside these areas.  Click here to learn more about the emerald ash borer.
