Could be improper pruning such as flush cuts.

I have 2 Maple trees that are probably 25 years old & 40-50 ft high.
They both have slices in the bark going up about 8-10 feet from the
ground & the bark is peeled away from the trunk about 4-5 inches on
both sides. What has caused this and why only these 2 trees and not
the others?

Hi Mike,

Just guessing, but could it possibly be lightning strikes? I
know of several trees around my area that have been hit by
lightning that look something like this.

Also tree may have been planted too deep and have girdling roots. Do you
have any cracks coming from the base?
