I need to take more photos and break the twig more cleanly, but this is what I have so far. Since we now have an RG "Zapatella herberti" I am posting these.
Most of the "twigs" in reach that seemed similar to JKehoe's observation had healthy twigs with leaves branching out from them, but I found one that had only a total of five leaves attached to its several branches.
There seemed to be a lot of types of insect damage to this one tree's branches, while the adjacent tree and the one across the path were much healthier.
Ok, just when I’m on my “baby blue oaks, no acorns, near the crown,” method for finding these, this bozo shows up.
