I have a real leaner that needs to be taken down and I'm a little unsure how to proceed. The tree is a yellow/paper birch with a few rotten top branches but the butt & trunk looks sound. I'm felling in the direction of the lean and, besides adjacent trees, there are no obstructions below.
Attached is a quick sketch. I was thinking of putting a narrow v-cut on the lower edge and then proceeding to back cut to the hinge. I also thought about boring to leave a hinge + strap and then cutting the strap to fell. My concern is that the sapwood of a yellow birch might not be strong enough for the strap given the weight of the tree and the extent of the lean.
Thanks,
Graham
