The beech leaf-mining weevil was first identified
<https://cfs.nrcan.gc.ca/publications?id=37778> as the insect
responsible for foliage damage on American Beech trees in the Halifax
area in 2012. I have a photo of damaged leaves on a tree near my house
in Waverley from 2011.
There are now very few beech trees still alive here, and the woods have
opened up markedly with the loss of so many trees. As far as I can tell,
all remaining beech trees are infected.
As long as there are living beech trees in Nova Scotia, I don't think we
can say that this has ended.

At Long Lake Prov. Park (Halifax), the majority
(>3/4) of Beeches had
most leaves eaten away or severely damaged. Some trees were nearly
bare. Unaffected trees were mostly isolated from other beeches,
typically young, scattered trees.
In a forested area in Cape Breton (Lime Hills), nearly all (>95%) of
the beech trees in the forests were dying or dead. Those were beech
dominated hardwood forests (other dominant species were yellow birch
and sugar maple), and the area was some 1 km from the next road (i.e.,
spread of the miner was unlikely by people).
I think the leaf miners have been around for at least 5 years. I think
to assess the impact, one would have to choose a sample area, and do a
bit of counting (# trees in area / # of trees affected / # of trees
healthy) and follow for a few years.

Dear All,
Early in 2021 there was concern about a Beech tree leaf
miner. Can
someone tell me how that ended.?
In the Kentville area, except for one patch of trees in a
location
normally wet year round and entirely dependent upon rainfall but bone
dry when I walked to it,they have fared well.
