When the emerald ash borer was discovered at Lake Wappapello last year, it seemed certain the green beetle would fan out across Missouri, leaving dead ash trees in its wake.
But so far, surveys conducted across the state this summer suggest Missouri's infestation is confined to the immediate area in Wayne County where it was discovered in 2008.
For now anyway.
