I hope there is something symbiotic going on here. A silver lining to this opportunistic invasion for the oak tree. Some benefit. I assume something living emerges from these things? What?
There are hundreds of critters who call Quercus food. I arrived at Oak Grove after the banquet. Trying to figure who was at the table by the patterns of foliar destruction and what kind of poop is lying around. Then they are microscopic opportunists. Viruses, blights, bugs on bugs… Tooth and claw.
