This little beastie has been making its way east (at my lattitude) for several years, and it's here. I have a few Ash trees out behind my house, and up on my rural property as well. I called NYS DEC and the county cooperative extension (and also Cornell cooperative extension) a few years ago to see if there is any way I could protect the trees (and help stop the spread of the borer). To make a long story short, the answer was "no". They've been spreading for a while, and the people studying it hope that the various species of Ash trees can be preserved (by saving seeds to repopulate), but existing Ash trees are all expected to be goners. Devastation of the Ash tree population, much like what happened with Dutch Elm disease a generation ago (but spreading much more quickly than that did).

p.s. Rich, you're missing an "r" on the name of the pest in your thread title. It's a borer, not a bore. (Well, maybe it's a bore too, to some anyway, but its name is Emerald Ash Borer).
