Storm damage, Boston vs Montreal?

I've lived in the Boston area for 60 years; been thru 8 hurricanes and tropical storms (including a category 3 and two category 2s)


and several super winter nor'easters with hurricane force wind gusts and sustained winds of 60mph or so. Then, a few years ago, I began a 2nd residence in Montreal. I have noticed that trees are broken and blown down in Montreal by storms less severe than those in Boston, such in the storm last week (29-30 November) that had highest winds (as reported) of 63km/hr (about 40MPH) with gusts to 78km/hr (less than 50MPH). Many trees were uprooted or broken, and large branches of others torn off, in spite of there being no umbrella effect from leaf canopies as the leaves had fallen in autumn. In Boston a similar storm would do no more tree damage than blow off a few twigs. Both cities have preponderances of maples, oaks and firs. Has genetic selection


so hardened trees in coastal New England to almost make sub-species that endure the more violent storms?

Storm damage, Boston vs Montreal?
I think you are right.
