Yard JM disease?

[BrightsideB]

I recently moved and this place has a jm in the yard about 15ft tall. I noticed this tissue trying to heal. Any idea what is going on and how to deal with it? I’ve thought about cutting the branches with this at a lower point. Not sure though

Do you have deer in the area?
Is the wounded area about antler height?
Based on the single photo it appears to be healing reasonably well.

What side of the trunk is this damage on? If on the southwest/southern/western side. It might be Southwest disease. Sounds fictional but it is a thing. In winter the suns rays fall directly on the bark. Thawing out the sap in it. If it’s cold enough that sap refreezes when the sun sets. Repeated the process severely damages the cambium resulting in split bark and dead tissue

If it happens in the summer I hear they call it sun scald
Sorry, I had to look that one up and it is official according to AI and the location is spot on.
Looks just like what happens during the "rut"
Something new every day.

@rockm thanks for the link! This in the photo is the most severe. And it is actually facing southwest. But there are other injuries less severe facing other coordinates I believe. I’ll look more into it though. And check it out later when I can.

@River's Edge it looks like it is at the height of a deer antler. I’ll get a better look at the other less severe injuries and see if they are all at similar height. I just moved in a couple months ago and noticed a fawn sleeping in the backyard and grazing a couple times. But didn’t seem interested in my trees in pots. My last place didn’t have a deer problem so this is going to be a learning experience.

I’ll upload some other photos. The tree is healthy so that is good. It’s a pretty big one.
