Mediterranean Oak Borer (Xyleborus monographus) on Sep 20, 2023

Submitter does not have a specimen
EDRR Status: Population assessed

Description of specimen

Certified arborist Morgan Holen assessed the tree on 9/19/2023. She observed frass at the base of the tree, significate crown die back, small borer holes and what appeared to be a MOB specimen in a spiderweb on the tree. The oak trees health has declined rabidly since last year.


As of 9/26/23: evidence of MOB found onsite on the one tree but not the others.
