I reread your thread, about going 2/3 up the tree. I would think it would
depend on the roots that you leave on the remaining live tree material. You state
that it is partially rotted at the base The remaining material has to have
enough root to support the tree. I would only be concerned if you plan to remove
more mateial from the base. The I would just make sure you leave enough roots
to support the tree growth
