Looked at this 21" DBH hickory today. My recommendation was to remove the chain link fence and fell it, as it's all the owner's property. (Would obviously need to avoid barber chairing it.) I am not too keen on climbing it and rigging down the heavier pieces. And I don't think piecing it down is cost effective.
Anyhow, anyone have insights as to why a mature hardwood would suddenly start uprooting? There's a definite hump opposite the lean due to the roots lifting. It has not been abnormally wet or stormy lately.
