Where Emerald ash borer has been found

EAB has not become established in every corner of the impacted states and provinces, including Missouri. There are still many EAB-free locations and it is very important that we do all we can to prevent the further spread of EAB. Below is a map of the states affected by EAB.

EAB distribution
 

While EAB has spread significantly since its original detection in the Detroit area back in 2002, as one can see from the map below, there are still a lot of vulnerable locations across the United States. (Download a PDF of this map.)

Ash tree range
 

The first detection of EAB in Missouri was in 2008 at the U.S. Army Corps of Engineers' Greenville Recreation Area in Wayne County. Since that first detection, the insect has been found in 11 counties. Below is a map showing the counties in Missouri that have been affected by EAB. (Download a PDF of this map.)
