It took me a while to get back from vaca but,  If your are involved in second, or 
third, crop forestry I can understand the root damage induced heart rots you keep 
seeing.  I *do not* see the same conditions around here during clearing for 
construction.  Most of the forests I see removed are second or third phase 
succession after farm abandonment, and so have not suffered through previous logging 
operations. In htses operations the rotted log is the oddball.
