Originally reported as Emerald Ash Borer (Agrilus planipennis)
Submitter does not have a specimen
Description of specimen
An Oregon ash growing along a cement "dock" at a barn. No signs of the exit holes for the borer, but suckers coming up from the base and vertical cracks (photo)
It's possible that the tree is growing so close to a cement block that it is stressed. It's also adjacent to a crumbling and decaying 100-year-old barn, so it could be another pest.
