About 4 years ago oak wilt really became noticeable here. The progression here was west to east, so western WI had 50% oaks dead 10yrs ago (total red and white). 5yrs ago saw the first white oaks die here. Now, there are a dozen dead on 20ac. All white. Plus all the red oaks from before. Seems they show signs a decade before according to the last 10 tiny rings left behind. Look for many tiny water sprouts, dead branch tips, leaves that just never seem glossy green and healthy, then shrooms on the trunk. If you don't see it now in southern Indiana, chances are you will shortly.
Yep, Reds getting slaughtered in our part of the country. I'll have to ask my brother what he's seeing in WI. He has some land out near the Mississippi in western WI, and resides northwest of Milw. He may also be seeing the progression that you've observed, Sawset.I havent noticed a widespread white oak disease here but the red oaks have really been hit hard here. I have tons of standing dead that i will sadly never get to. Im not sure what it is but from judging pictures from what i can make of it the disease is called hypoxylon canker. It literally has killed tons of mature red oaks in this part of country.
