Oregon Ash Disease – transient, we hope

Full account here.

12 September 2023: Leaves with distorted shape and size dominate parts of many of the forest’s Oregon Ash trees. Total foliage in some is sparse. I think the initiation of further distortion ended with the summer dry period. The trees otherwise seem healthy. And if protracted spring/early summer rain recurs only infrequently, in future years, I predict no lasting harm to this species. I will continue to watch.
