Some of you may remember the devastation that Dutch elm disease wrought on elm trees across the country. Well, something similar is happening now with ash trees and the emerald ash borer. The insect can kill a tree in as little as three years The emerald ash borer is an exotic insect. It was first documented in the United States in Michigan in 2002, and has been spreading since. Our native ash trees are very susceptible to this insect pest, which can kill a green ash in as little as three years. I have not seen any statistics on the mortality rate, but it appears to be comparable to that of Dutch elm disease.
