The NC Forest Service has just shared that Wake, Orange and Durham counties are joining the quarantine area for emerald ash borer. This has wiped out millions of trees in Ohio and Michigan. Locally I have noticed that with new road construction often shade trees are not replaced. This needs to change. The easiest way for the ash borer to spread is to move firewood from one county to another. This also needs to change.

Addition information about the emerald ash borer and the quarantine can be found at these websites.
