Every fact cited
Canopy thinning, D-shaped exit holes, bark splitting over S-shaped tunnels, and heavier woodpecker activity remain the signs to know. Pierre’s Missouri River corridor trees can also show stress from water-level fluctuations around Lake Sharpe — look for the more EAB-specific markers before assuming that’s the cause.
Frequently Asked
01
Could Lake Sharpe water levels affect my ash tree's canopy?
Fluctuating water levels can stress root systems near the shoreline, which can look similar to early canopy decline. An arborist can distinguish that from EAB-specific signs like exit holes.
