Canopy thinning starting at the top, D-shaped exit holes, bark splitting over S-shaped tunnels, and heavier woodpecker activity are the signs to know. Prairie wind and periodic drought are common, less serious causes of thinning in Huron — look for the more specific markers before assuming EAB.
Frequently Asked
01
What's the difference between drought stress and EAB damage?
Drought stress tends to affect the whole canopy fairly evenly and improves with better conditions; EAB damage typically starts at the top and progresses even when water and weather conditions are otherwise fine, and comes with exit holes or larval tunnels an arborist can confirm.
