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.
