Flush Cut Dissected

We were recently contracted by a family in Newberg to evaluate their trees and perform the indicated work. I noticed that a large Oregon White Oak which leaned over their bedroom had a large flush cut wound on the central stem that was not closing. Upon inquiry I learned that the tree had been pruned about six years ago. Given the size of the oak, its proximity to their bedroom, and the advancing decay in the stem a recommendation for removal was given. Here are photos to confirm our judgment. It is also confirmation that improper pruning can cause serious damage to a tree, which can in turn present us with potential hazards.

A large flush cut with a poorly sealing wound has here been ripped down the center

Notice the decay extending downward into the stem
