Believe it or not, not all forest tree problems from 2021 were from drought. Some of them stemmed from the floods of 2019 and others had to do with hungry squirrels! The drought certainly aggravated stresses of the past, caused problems of its own, and set up many trees for problems in 2022. Drought-related tree problems like leaf scorch, twolined chestnut borer, and pine engraver beetles will be covered. Other forest health items we observed will be sprinkled throughout the talk as well.
