Pale, blond patches on ash bark this fall are often an early sign of emerald ash borer in Baltimore County and York County. Woodpeckers strip the outer bark while feeding on the larvae underneath, and the flecking is easiest to see once the leaves drop.
Other signs include thinning at the top of the crown, small D-shaped exit holes, and new sprouts along the trunk. By the time dieback is obvious, damage beneath the bark is usually well advanced.
Healthy, valuable ash trees caught early can sometimes be protected, while trees already in decline become brittle quickly and are safer to remove before limbs start to fail. Crass Tree Experts inspects ash trees across Baltimore County and York County to help property owners understand which situation applies.
Fall and winter are the easiest seasons to check ash trees, since bare branches reveal both canopy thinning and bark damage clearly. Early detection gives property owners more options and more time to plan.

A close-up of an ash trunk showing woodpecker flecking (pale patches where outer bark has been stripped), ideally from a real Baltimore County or York County property. A wider shot showing a thinning ash crown also works. Authentic job photos from real crews and real properties strongly preferred over stock images.
