Emerald Ash Borer in Southern Nevada?

Emerald ash borer damage to
Green ash. From Wikipeida.

Q. Each summer when I vacation I note the westward movement of the Emerald Ash Borer, now in Eastern Nebraska.  Is it safe to assume this menace will make its way to Nevada and, if so, is there any defense against its damage?  It seems that Ash trees make up a large portion of the urban canopy here, many of which are already stressed by lawn removal.  Do you anticipate a problem? 

A. There is a good chance it will not reach southern Nevada and become a problem. It is currently restricted to lower Canada and the northern tier states extending as far south as Missouri as far as I can tell. Our climate may not be favorable for its spread. But we will not know until it gets here and it will get here. Also the ash trees it favors seems to be northern zone ash trees. Let’s keep our fingers crossed on this one.
