I think that many were trees planted over 100 years ago and it was not well thought out as to the possible drawbacks once they became mature.
When we first moved into our home 45 years ago, I planted 3 conifers each about 1ft. tall. I never considered how big they would become. All were felled some years ago and they were enormous!
