Ash: A Clear Sign

Emerald Ash Borer has been on the march for many years, and now the trees at our place are obviously infested.  This is classic.  The tips are dead, the leave coming out are the normal green color. (Not yellow, as trees with Ash Yellow Disease.) There are lots of epicormic sprouts, similar to the response to Ash Yellow.

Ash is prolific, and when you see the amount of reproduction ash trees produce, you would expect it to dominate. It usually is poorly represented in mature stands of timber, and I blame Ash Yellow for that.  Now we have the borer, and it attacks trees of all ages.  I don't know the future for ash in future eastern hardwood forests, but it looks as though it will be an extremely rare commodity.
