Good morning!
I am sorry to hear about your oak - do those lighter green spots turn brown or do they just stay the light green and dry out?
Would you be able to send a few more photos of the entire tree? Including the base of the tree.
Has the treatment for silkworms helped the tree in the past and this year it is just not bouncing back?
Did your neighbor take any photos of the holes when they climbed it?
If I cannot diagnose on the follow-up photos you send, we have a diagnostic team at our office that can take a look and run a few tests to see if we can diagnose it!
Thanks so much for reaching out,
Rachel

Susan, thank you for reaching out to us. I am sorry you are having issues with this beautiful oak. The pics are very helpful.
This year we are seeing damage similar to this cropping up on oaks on the front range. Our CSU professionals are trying to sort this out.
I would highly recommend you bring a sample to our office so our diagnostic professionals could make an accurate determination. This is especially important since we are seeing this damage to other oaks this summer. With an accurate diagnosis’s we would be able to give you a helpful recommendation.
Our office is at 9595 Nelson Rd, Longmont. We are on the eastside of the fairground complex. Our office hours are 8:00 to 4:00. Our office is located in the basement.
You can drop the sample off and fill out a question sheet. Our team will examine the damage and get back to you.
Some questions to provide answers to when you come in.
- How old is the tree, if known.
- Do you know the variety of oak
- How long have you lived at the property
- Do you have other oaks on the property, or nearby property, that are being similarly affected

The holes appear to be woodpecker damage based upon the pattern. There could be other sources of the damage. However, if you are seeing woodpeckers around it is likely damage from them.
