ld growth Beeches are susceptible to the insect/
--001a1141f6da5e0aaa052fb0e772
Content-Type: text/plain; charset=UTF-8
We have a very old beech, about a metre diameter breast height, that is on
a property line in South Berwick and is not noticeably infected. All the
beech in the woodland that once would have been filled with our old beech's
cohort are junk..infected usually just after the whip stage and dying
before 15cm DBH. Imagine if grandparents of the junk beech had not been cut.
There is a collection of beech almost our ancient one's size along Miner's
Marsh, on that south slope that goes up to Belcher Street just up from the
Catholic Church. These have had a hard time in recent years but they
probably were set up before the disease came. It does seem that when the
beech gets past a given diameter (30cm?), its main trunk is mostly
resistant; you'll see chancres on the upper smaller branches but not the
main trunk.
Jamie Simpson wrote an article about this syndrome and resistance. Some
trees seem to be resistant. It is hard to tell in the field because of
factors like wind direction and proximity and infection density etc. I
think we have a couple of resistants on our property but I wouldnt want to
inoculate and test them. We are seeing hemlocks spread into former beech
woods and it makes sense and has been written on that this long-lived
shade tolerant queen would replace the diseased beech..that or sugar maple.
Donna Crossland had some resistant beeches developed by Forestry Canada, if
I recall right.
The diseased trees keep at it. They are shade resistant but they seem to
get out some nuts so young diseased beech keep stepping up and replacing
the dead.
Miner's Marsh old growth beech slope is a valuable spot ..only one I know
like it..and we should alert Kentville town that one of the houses is
dumping fill and waste down this slope from Belcher street, much to his
neighbour's dismay.

Good luck with the Beeches. Here in Waverley they are being wiped
out by an introduced beetle, the <a href=3D"https://www.invasiveinsects=
.ca/blmw/blmw.html" target=3D"_blank">beech
leaf-mining weevil (Orchestes fagi)</a>. Many of our trees have
been defoliated year after year and are now dead.<br>
