They talk about oak wilt, but I have no idea on how to diagnose it.
I suspect last summer’s drought caused many things to flare up.

We have oak wilt hear in Bloomington and depending on the variety of Oak can take a number of years for a tree to die. Longer for whites and shorter for reds. Their leaves get very thin at the top and work their way down the tree. I have a white that has been dying for 6+ years.

Two lined Chestnut borer was the name mentioned by the forester in our area.

The trunk damage on the first picture makes me think lightning damage. A big oak in my parents yard was hit by lightning and it looked like that. It kills a section of the bark and then the tree tries to heal over it.
Oak wilt is pretty common down here in our area. It tends to hit the red oak family (red, black, pin) hardest and spreads slowly from one tree to the next. Often the trees will leaf out and then die, so it is pretty easy to recognize. I logged my woods last winter since it was clear most of the black oaks weren't destined for this world.
I don't know the cause of your oak issues, but I don't think there is much you can do about it one way or other.

The wound in the first photo looks like an injury scar that did start to heal. Possibly a logging injury or lightning strike?? Probably not the cause of it dying but, certainly didn't help. It's tough losing older trees. I lose an old apple every 2-3 years. |

I've got some large burr oaks dying not far from the house. No visible trunk injuries. I talked with another old guy not long ago about oaks dying and he has some old burr oaks dying too. He blames three successive years of drought. I have no idea what's killing them. If I heated with wood I suppose I'd be happy.

bad enough losing so many red oaks to oak wilt, now this happening. I am seeing the same thing here and up north.
I am going to have only buckthorn left for cover some day the way its going.

There was a huge white pine up north that was my Dad’s favorite stand. It was big when I was a kid. It went down two years ago.
These things remind me of where we are all headed.

I'm worried about the invasives more than ever. We have Japanese knotweed all over the roads in NH and the state DOT is the cause of the spreading. Throw in buckthorn that has emerged around my town the past couple years and the invasive vine plants. Then I have to chuckle when the USDA drags out the Darling 59 chestnut approval while all of the invasives and diseases roll in from China. |
