This just in... Would be interested to know if anyone sees this in their woods come spring.
Will keep an eye out next growing season, Brett. Does it ultimately result in any mortality? In the meantime, it might reduce effectiveness of glyphosate foliar spray due to compromised leaf and conductive tissue in twigs/branches.
I only know what the articles say (which isn't much). Sounds like mortality is quicker in smaller trees, and less so in larger ones. This may be a welcomed "natural correction" in areas overrun with beech brush, but would be a real threat to the few large healthy (presumably, beech bark disease resistant) beech that are still out there. At the Arnot, we've been working this year with some plant geneticists at Cornell to map the genome of large, healthy American Beech in hopes that we can eventually propagate and distribute offspring from these trees.
Nice to hear that work is being done with apparently resistant trees. Clear beech boards are attractive when finished and of course beech nuts are fabulous wildlife food.
I hope beech leaf disease doesn't become a landscape-wide scourge. We have enough of such problems already.
