Emerald Ash Borer is severely affecting all species of this genus. Damage can be prevented with the appropriate pesticide, but the treatment cost will eventually exceed replacement cost. See the Purdue Landscape Report article: Should ash trees still be protected from emerald ash borer? for more information
