Kentucky Lingering Ash Project

Some untreated ash trees, known as lingering ash, still remain on the landscape years after surrounding, untreated ash trees have succumbed to EAB.  These lingering ash may play an integral role in eventually returning ash trees to the landscape.  The University of Kentucky and the Kentucky Division of Forestry are working to: 

  • Identify lingering white and green ash in Kentucky,  

  • Collect seed from these ash trees 

  • Grow white and green ash trees from these seeds  

  • Determine whether these trees might carry some resistance to EAB

In areas where greater than 95% of native white and green ash trees have succumbed to EAB, lingering ash are those trees that remain in good health.

Lingering ash trees cannot be treated for EAB with and insecticide to be considered lingering ash. Rather, they must be untreated, naturally growing (not planted) trees to be classified as lingering ash.
