Fraxinus spp.
Ash

Fraxinus (Ash) is a genus of about 65 species of deciduous trees native to the northern hemisphere, including North America, Europe, and Asia. Until recently, plants of this genus had been very popular for use in the landscape, and commercially, as timber trees, given their very hard wood. Unfortunately, this genus is now being severely affected the Emerald Ash Borer (EAB). Damage can be prevented with the appropriate pesticide, but the treatment cost will eventually exceed replacement cost.
