This may be too late for the tree in question, but if a guy can dig a trench around it pretty deep and fill it w/peat moss a year ahead of time, it will allow roots to grow back where you dug the trench. When its ready to move, then the taproot can be cut, and hopefully the new roots can take over. 'Course it may still die. I have, in the past,(before 9-11) blown out saplings w/dynamite after having dug around, and (mostly) had good luck. A blasted spot where you aim to transplant it will loosen up the soil and get the tree off to an easier start. We ain't talkin' Heroshima here, just "loosening" the soil, which could be done w/BP.
