Signs of EAB: Woodpecker Activity. Native woodpeckers are the primary predators of emerald ash borer (EAB) in North America and are the most important source of EAB biological control. Patches of light-colored bark on upper portions of ash trees are likely locations where woodpeckers have recently peeled away bark to remove EAB larvae. "Blonding" is often the first evidence that EAB is present in a local area.

As leaves begin to fall, bark "blonding" becomes increasingly visible. Look for these marks from woodpeckers that often indicate the presence of #EmeraldAshBorer.

A recent study from UIUC shows that #EmeraldAshBorer and #DutchElmDisease have driven declining biodiversity in the sampled woods—and likely beyond—through impacts extending beyond just the loss of these two tree species.
