Did you notice any beech trees with any resistance to the
Foresters should strive to retain "smooth barked beech" or beech
that show partial to full resistance to the disease. They may only
represent a small percentage of beech so it's important we try and
promote these resistant trees.
Beech is a small component of the white pine, hardwood
forest where most of my work is in north central MA but in the
Berkshires of western MA there's often a lot of that miserable beech
regeneration. The only way to control it is through herbicide
None stick out in my memory. I only mention 90% in that not all
of them had
succumbed, but whether the remaining ~10% will survive is still
be seen. It appeared that all mature/ancient beech had it, it just
as to what extent.
I totally agree with beech in the forest setting. We may often
hear to just
cut them all down, but that means removing any chance of any
to survive. At Cook Forest, they've decided to leave the "forest
beech go, but a couple of years ago they removed any beech that had
disease around heavily used public areas (campground, etc.) because
safety issues. It's still working through beech around the
were spared on the first wave.
Large disease free beech is a rare sight. But what a sight they
you are lucky to see one. More common are beech that are partially
resistant. While you may see most beech trees ravaged by the disease
covered by hideous and decaying cankers, in the midst of those you
see beech that is mostly smooth barked and where smaller cankers are
appearing to heal over. On those beech trees that appear mostly
resistant, is there something in the bark that the European Beech
doesn't like? Fewer openings by the scale insect mean less
for Nectria canker to colonize which means the tree doesn't have to
and fight on too many fronts so they are more successful in walling
the cankers that do become established.
The US Forest Service have done some studies which suggest ways
and limit beech regeneration during timber harvesting like logging
winter when the ground is frozen so as not to disturb the beech
which sprout prolifically and you may not get as much stump
from the beech either.
European beech was a commonly planted ornamental and I see big
occasion when I go to suburbia. How are they able to resist Beech
In the years I 'forested' in SE Kentucky, I saw many smooth-barked,
either disease-free or -resistant beech, in the 18" to 30" diameter
classes. While I hated getting whipped in the face by the little
sapling branches where regeneration was thick, I liked them as a
species...they did have a weakness in mountainous country with a lot
of wildfires...their thin bark did little to protect them, and it
was real common to have the topside of the base burned out from
fires that would get 'captured' there. Eventually after repeated
exposure to fires, they'd two-, three-, or four-legged from being
hollow inside. I hated to see them along fire-lines as they were a
challenge to fall, on-fire or not.
That was in the late-80's, don't know how they're doing these
RE: [ENTS] Re: Hearts
You write, "While you may see most beech trees ravaged by the
disease and covered by hideous and decaying cankers, in the
midst of those you might see beech that is mostly smooth barked
and where smaller cankers are appearing to heal over." I spend
a fair amount of time hiking around and would like to be able to
distinguish beech trees that are resistant. I can mostly
visualize the effect you are describing and will watch for it.
I am familiar with unaffected beech, and with beech dying from
canker and infection. I am just not sure I have seen any with
the canker scars healing. Do you have, or are there photos on
the web that illustrate this phenomena?
You know how it is; you never have a camera when you need one. I
you guys carry cameras with you all the time and maybe I should too
I go in the woods. Iíll try and take some shots of beech trees this
Earlier in the year I wish I had my camera to take some shots of
rather extraordinary beaver girdling. There was a 24Ē+ DBH white ash
that was girdled and then I saw an oak where the beaver made a notch
the way through nut somehow the tree didnít drop!
I'm in the same boat as Ed when it comes to being able to
I either see them clean in sites with no disease, or see some
clean in sites
with the disease. But, since Cook is likely somewhere in the
the "wave", I'm not sure what disease resistant ones look like after
wave has passed.
I have seen a few beech over the years that show a series of
the lower section of trunk. Kind of like a warty/healing texture on
bark, say about slightly smaller than a golf ball, and many of them
tightly together. But, this type of character was present on beech
the disease "wave" got here. I figured it was healing from some
attack, be it insect or otherwise, but still haven't had anyone be
tell me exactly how they got there. Maybe this is the character, or
something similar, that you're trying to describe to look for
I saw a similar "noduled" 18" DBH beech on a woodlot
yesterday. It was covered in these small bumps all up and down and
around the tree like little ski moguls. The crown of this large
looked very good. So I would consider that beech to be partially
resistant because those nodules are actually healed over cankers. I
would retain a tree like that because large mast bearing beech trees
with decent live crowns are rare in these parts.
"ski mogels"... yeh, that's the character. I agree, they should
be left in tact.
